Title: Method and apparatus for pile fabric processing
IPC: D06C23/00
Filed: 1971-09-02
Abstract: 1361444 Finishing fabrics H HERGERT 2 Sept 1971 [27 May 1971] 40994/71 Heading D1S A pattern effect is produced on a synthetic pile fabric 21 by passing the fabric over a pattern roll 10 whilst it is brought into contact with a processing element 30, e.g. for heating, cooling, ironing, beating, brushing or electrifying the fabric, the roll 10 being mounted on means 29 pivotable about an axis 35 parallel to the axis of the roll 10. As shown in Figs. 1 and 3, the roll 10 is formed with longitudinal slots 12 in which desired pattern profiles are releasably mounted by bolts 15 and nuts 16. Preferably each profile has a concave surface shaped to conform to the roll surface, the roll 10 is heated internally and the profiles 13 are made of a heat conductive material.  In the apparatus of Fig. 2, the fabric 21 passes around idler rolls 22, 23, 24, 25 and driven feeder and delivery rolls 27, 28, respectively. A pile beater 26 is provided and the roll 10 is positioned close to an electrifier cylinder 30 disposed within an exhaust hood 31. The rolls 10, 23, 24, 25, 27, 28 and the beater 26 are mounted on a carriage 29 pivotable about an axis 35 and having a worm lifter screw 36. The roll 10 is slidable on a rail 39. The roll 10 and the rolls 27, 28 may or may not be driven from the same drive.  In modifications, the cylinder 30 is replaced by (a) a concave ironer plate, Fig. 8A (not shown), (b) two pressure heated cylinders mounted upon parallel: axes and which may have surface designs, Fig. 8B (n.s.), (c) a pressure roll which may have a contoured face with sculptured or plain profiles and may be heated, Fig. 8C (n.s.), (d) a rotary brush having its axis parallel to the axis of the pattern roll, Fig. 8D (n.s.), (e) swirling brushes rotating about an axis perpendicular to that of the pattern roll, Fig. 8E (n.s.), and (f) swirling electrifier units disposed along and perpendicular to the axis of the pattern roll, Fig. 8F (not shown). The fabric may be preheated before entry into the treatment zone and cooled upon exit therefrom. The non-pile surface of the fabric may be heated in the treatment zone. Two treatment zones may be provided to affect the lay of the pile fibres in different ways.

Title: Fuel spray nozzles
IPC: F23D11/24
Filed: 1961-11-16
Abstract: 928,629. Spray burners. GENERAL MOTORS CORPORATION. Nov. 16, 1961 [Dec. 12, 1960], No. 41025/61. Class 75 (1). [Also in Group XXIX] In a fuel spray nozzle, a finned valve body 62 slides in a cylindrical valve guide 56 and is moved by fuel pressure against the action of a spring 68 to allow the passage of fuel through the valve guide. The valve body 62 comprises four fins 78 on a stem 74 over which is fitted a valve head 64 having two V-shaped slots 84 which are aligned with two diametrically opposed fins. The spring 68 acts on the valve body through a seat 72 shaped to engage the contoured end of the head 64, and movement of the body 62 in the direction of action of the spring is limited by a pin 66 mounted in the valve guide. The nozzle comprises concentric low and high capacity spray tips 18 and 16, the former always being fed by fuel from a filter 20 via a passage 28, tangential ports and a swirl chamber. As the fuel pressure acting on the valve body 62 increases it moves the latter against the action of spring 68 causing the V-shaped slots 84 to emerge from the valve guide 56 so that fuel can pass from the filter 20 into a chamber 24 and thence through tangential ports to the high capacity spray tip.

Title: Improvements relating to turbine plant for marine propulsion
IPC: B63H23/00
Filed: 1959-12-03
Abstract: 887,054. Elastic-fluid turbines. HASENCLEVER, E. Dec. 3, 1959 [Dec. 5, 1958], No. 41119/59. Class 110 (3). A steam or gas turbine marine propulsion plant comprises at least one ahead turbine and at least one astern turbine which is normally disengaged from the former, means for accelerating the astern turbine in the ahead direction of rotation, and means for coupling, at or near synchronous speed, the astern turbine with the ahead turbine or reduction gearing associated therewith. A free piston gas generator 1 supplies working fluid either to an ahead turbine 2 which is normally disconnected from an astern turbine 3 or to the astern turbine 3 which has an auxiliary turbine 4 with ahead blading. A freewheel and coupling device 10 allows the astern turbine to be rotated in the ahead direction into synchronism with the ahead turbine by the auxiliary turbine 4 whereupon the freewheel is locked to provide a rigid connection therebetween. The auxiliary turbine may be replaced by a row of ahead blades on the astern turbine. In the freewheel device, Fig. 2, a shaft 11 is connected with the astern turbine 3 and a shaft 12 with the ahead turbine 2 or its gearing 5. When the astern turbine is accelerated by the turbine 4, rollers 14 of the freewheel device lock on synchronism and transmit a small residual torque from the turbine 4, whereupon a coupling sleeve 16 splined on the shaft 11 automatically establishes a positive-connection with the freewheel drum 13 through interengaging teeth 17. An overrunning clutch may replace the freewheel, in which case the teeth 17 have inclined faces to repel the opposing coupling parts except at synchronous speeds. These operations are preferably interlocked so that the coupling teeth cannot engage if a substantial speed difference exists between the ahead and astern turbines and the astern turbine receives no working fluid before the freewheel is locked. More than one ahead turbine may be installed for each astern turbine.

Title: Method of and apparatus for filling the tubular plates of lead-acid storage batteries
IPC: H01M4/20
Filed: 1973-09-04
Abstract: 1386056 Lead storage battery electrodes L BOHLE 4 Sept 1973 [4 Sept 1972] 41606/73 Heading H1B An electrode comprising a number of porous insulating tubes 15 arranged side-by-side, each tube having a lead spine 14, is filled with active material by adding to a conventional leadpaste mixture additional water to form a suspension, and forcing the suspension into the tubes. The quantity of additional water is approximately equal to the amount of water already present in the conventional paste mixture and serves to reduce the viscosity. The filling apparatus comprises a metering pump 8 containing the suspension connected to a distributer 9 through a quick-acting valve or gate 3/13, nozzles 10 at the outlet of the distributer being coupled to the inlet ends of the tubes 15. Actuation of a plunger 2 by a rod 5 and opening of the valve or gate 3/13 causes a measured quantity of the suspension to be injected into all the tubes 15 simultaneously.

Title: Apparatus for sampling gases
IPC: G01N33/497
Filed: 1973-09-05
Abstract: 1440785 Gas samplers CAND-AIRE INDUSTRIES INC 5 Sept 1973 [5 Sept 1972] 41652/73 Heading A5R A gas sampler, e.g. for breath sampling, comprises a partially evacuated canister 10 having a valved inlet fitting 12 to which is connected a flexilble sampling tube 14 at the inlet 20. The inlet is closed by a spring-loaded valve (18), Figure 4 (not shown). The wall of the tube 14 has a longitudinal slit 28 of length about 5 cm, acting as a pressure relief valve, which only opens when the pressure in the tube 14 is above atmospheric pressure. The canister may be made of any material of adequate strength such as metal, plastics, cardboard or glass, and a metal aerosol can is suitable. The sampling tube may terminate in a mouthpiece 16, and it may contain an inner tube 24, which senses to reduce the dead volume within the tube 14, and which passes through a seal 26 near the outer end of 24. In an alternative embodiment (Figure 2, not shown) the tube 24 is omitted. In use for breath testing, the subject exhales into the mouthpiece 16 and upper lung air escapes through the slit 28. Near the end of exhalation the inlet valve (18) is opened so that a sample of deep lung air is drawn into the canister. Then the inlet valve (18) is released, the fitting 12 and tube 14 are discarded, and, to secure the stem of the valve (18), a short length of tubing is crimped on to it. Preferably the device is prepared for use by purging with an inert gas such as nitrogen, followed by partial evacuation to a vacuum of not more than 15 inches of mercury. The degree of vacuum is chosen in relation to the vapour pressure-temperature characteristic of the component to be analysed so that condensation in the canister will not occur at the lowest temperature to which the sampler will be subjected. To permit hypodermic extraction of a sample from the canister after use a recess (36) (Figure 4, not shown) in the wall is provided, filled with a self-sealing material (34) such as room temperature vulcanising silicone rubber to seal the puncture. A suitable gaseous standard, such as methyl ethyl ketone for alcohol analyses, may be introduced into the sampler either initially or hypodermically through the recess (36) after the sample has been taken. The concentration of a gaseous constituent may then be determined by comparison with the concentration of the standard by a method such as gas chromatography.

Title: Improvements in or relating to the magnetic recording of data in analogue form
IPC: G11B20/16
Filed: 1966-09-19
Abstract: 1,134,472. Magnetic recording. COMPAGNIE DES COMPTEURS. 19 Sept., 1966 [13 Oct., 1965], No. 41697/66. Heading G4C. In a process for the magnetic recording of data in analogue form on a recording track, a digital signal is recorded on an auxiliary track prior to each of a succession of experiments to specify the experiment number, the current value of the signal being incremented by one for each new experiment. In Fig. 1, a quartz clock pulse generator 1 generates clock pulses H, from which pulses H/2 and /H32 are obtained by frequency division at 14, 15. When analogue data from an experiment (e.g. physiological) is to be recorded on a track of a magnetic tape, a manual or automatic signal, M or I c , to a control unit 2 causes an H/32 clock pulse to be recorded on a further track II of the tape, by gating at 12A, allows a ring counter 5 to start counting H/32 clock pulses, and triggers a monostable flipflop 7 to apply a pulse to an adder 8 to increment by one the number (binary) of the previous recorded experiment applied serially from a shift register 9. Each incrementation of counter 5, except the last, gates at 6 a corresponding bit of the adder output back to the register 9. The adder output is also recorded on track II via OR gates 4. The last incrementation of the counter 5 prevents further incrementation of the counter, at gate 5A, and triggers the experiment via I D . The H clock pulses are recorded on a track I, and whenever a manual or automatic signal M<SP>1</SP>, I M  is received at a circuit 3, one of the H/2 clock pulses is recorded on a track III In a playback circuit, the first pulse on track II causes the subsequent pulses (the experiment number) on the track to be gated to a register for decoding and optical display. A gating pulse for this purpose is obtained on each incrementation of a ring counter driven via a frequency divider (divide by 32) by the H clock pulses from track I between the time of arrival of the first pulse from track II to the reaching of counter capacity. The recorded experiment numbers facilitate selective copying of the various tracks to a second tape, control of a camera photographing an oscilloscope screen on which the analogue data is displayed, searching for the data of a given experiment using a digital comparator, and preparing from the tape above of a second tape bearing the digital equivalent of the analogue data (in this case the analogue waveform may be sampled by clock pulses from track I, and the number of the experiment and of the originating analogue track be also recorded on the second tape to facilitate processing of the second tape by computer). Digital recording may be as in Specification 908,547, it is mentioned.

Abstract: 1,198,009. Magnetic structures. KALLE A.G. 3 Sept., 1968 [4 Sept., 1967], No. 41854/68. Heading H1H. A magnetic tape comprises a biaxially stretched polyester film base, a layer of conductive carbon black particles attached to one or both film surfaces without an applied binder, and a layer of ferromagnetic particles in a polymer binder. The carbon black layer may be applied by treating the film surface with a dispersion of carbon black in a solvent or swelling agent for the film material, and removing the solvent or swelling agent by heat, e.g. at 120-200 C. Suitable solvents are phenols and their derivatives and halogenated hydrocarbons or low fatty acids (examples given), which may be employed as 5-30% aqueous solutions. Anionic or non-ionic dispersing agents may be used. The covered surface may have 0À05-2À5 g/m.<SP>2</SP> of carbon black, and a surface resistivity of 10<SP>8</SP>-10<SP>3</SP> ohms. The conductive layer may also contain graphite or P.T.F.E., and is preferably not more than 2Á thick. The ferromagnetic layer may be applied on the outside of, or on the opposite side to, the carbon black layer, using a dispersion of ferromagnetic particles in a solution of the polymer, and then heating to remove the solvent and optionally to harden the binder, e.g. in an air stream at 60-150 C. The ferromagnetic particles may be acicular #Fe 2 O 3 , ferrites, magnetite, or CrO 2 . The binder may be a vinyl chloride/vinyl acetate copolymer (Ex. 1) or a polyester urethane (Ex. 2); other polymers are mentioned. The base is preferably polyethylene terephthalate, produced at a stretching ratio of at least 1 : 6.

Title: Refrigerant evaporator assembly for air conditioning system
IPC: F25B39/02
Filed: 1973-09-06
Abstract: 1444609 Evaporators NISSAN MOTOR CO Ltd 6 Sept 1973 [6 Sept 1972 (2)] 41915/73 Heading F4H A refrigerant evaporator assembly for a vehicle air conditioning system comprises a fin and tube heat exchange unit 12 having a tube bank 22 projecting through an end wall 18, an expansion valve 14 through which refrigerant passes into a distributing chamber 34 and inlet  tubes 28 of the unit 12, and a pressure regulating valve 16 for receiving refrigerant from a collecting chamber 36 and from outlet tubes 30 of the unit. The valves 14, 16 and the chambers 34, 36 form part of a sub-assembly mounted on, or integral with, said end wall 18. In Fig. 1, the tubes 22 of the unit 12 are connected by tubes 23 to form several refrigerant coils. Each coil has an inlet end 24 and an outlet end 26, the ends 24, 26 being connected by the tubes 28 and 30 respectively to the chambers 34 and 36. The collecting chamber 36 houses a bulb 38 attached to a diaphragm operatively connected to the valve member of the expansion valve 14. In operation of the refrigeration system, as the temperature within the collecting chamber rises, the pressure of the gas increases to urge the diaphragm leftwardly (as shown) against the action of a spring to move the valve to increase the flow of refrigerant into the heat exchange unit 12. The regulator valve 16 is in the form of a pressure relief valve 44. If the pressure rises, the valve 44 is urged downwardly against spring pressure to uncover a passageway to an outlet nozzle 46 which permits the flow of refrigerant to the compressor. In another embodiment (Figs. 3-6, not shown) the assembly includes a plurality of U-tubes, and three plates bolted together and so apertured and recessed as to form the end wall 18 and the chambers 34, 36.

Title: Code translator
IPC: G11C15/04
Filed: 1970-09-03
Abstract: 1320370 Code translators WESTERN ELECTRIC CO Inc 3 Sept 1970 [3 Sept 1969] 42126/70 Heading G4H A code translator 10 comprises a number of input buses 27, 28, 29, 31, a set of output lines 33, 34 and diodes 36-39 interconnecting the input and output lines so that energization of any input bus produces a unique energization pattern of the output lines and means, responsive to a first unique pattern which, with a second unique pattern, would constitute a third unique pattern, for inhibiting the energization of the input bus corresponding to the second unique pattern. The input buses are normally held at earth potential by corresponding transistors 22-24 and 26, the "0" signal at input terminals 17, 18, 19 and 21 being a positive voltage serving to keep the corresponding transistors conducting. A "1" input signal of zero volts turns the corresponding transistor off and allows the input bus to go positive. Diodes 36, 37 connect the bus 31 to both output lines, diode 38 connects bus 29 to output line 33, diode 39 connects bus 28 to output line 34 and bus 27 is not connected to either output. If input 19 is marked, the output is 1, 0. The signal on lead 33 switches on transistor 41 to earth input bus 28. A further input on terminal 18 therefore has no effect. This prevents a double input giving a false 1, 1 output which is the pattern for input 21. The inputs are arranged in an order of priority, the highest priority being input 21 which energizes both outputs causing transistors 41 and 56 to conduct inputs 18 and 19, and transistors 52 and 53 to conduct to disable input 17. Similarly input 19 disables inputs 18 and 17 and input 18 disables input 17. The priority between inputs 18 and 19 is given by a resistor 56 which enables the effect of transistor 24 to overcome the effect of earthing transistor 54 should this have previously been turned on by input 18. If any input bus is energized an output is given through diodes 42, 43, 44 and 46 and transistor 47. Four circuits 10-13 as described may be connected to a fifth such circuit 14. Of the sixteen inputs only one should have a signal. The output leads 33, 34 &c. are combined to give final outputs on leads 48, 49. The outputs 417, 418, 419 and 421 which identifies the decoding circuit 10-13 which has the input signal, are taken to the fifth decoder 14. The outputs 433 and 434 of this circuit with outputs 48, 49 pass the recoded equivalent of the marked input terminal.

Abstract: 1,007,066. Container closures. BOUCHON RAPID. Oct. 25, 1963 [Dec. 22, 1962], No. 42154/63. Heading B8T. A metallic capsule for bottles and like containers has radial lugs 12, 14 and 15 formed by cuts 18 and 19. part in the skirt and part in the top of the capsule, extending from points short of the free edge 20 of said skirt towards the centre of said top, and at least one circular groove 22 formed in said top and intersecting the inner ends of said lugs. On crimping the capsule on to a bottle, the setting of the pleated skirt causes the inner ends of the lugs 12, 14 and 15 to be bent slightly upwards to a position from which they may easily be lifted and torn off to remove the capsule. The capsule may be used with a gasket to give tighter sealing. The gasket of Fig. 11 is a plastics flanged cup with the flange connected to the cup by means of a circular fillet 36 and by means of a groove 39, together providing a flexible hinge between the flange and the cup. To facilitate the removal of the gasket a circular tear-off line 47 may be provided which when torn leaves a gripping ring. The gasket may also be a disc formed with an integral depending cylindrical sleeve, the outer edge of the disc being formed with a bead or being connected to an external skirt over which the capsule fits. The top of the capsule may be provided with a plurality of concentric grooves, the main groove in all cases having an outer diameter approximately equal to the inner diameter of the bottle neck.
