Title: Improvements in or relating to recording apparatus
IPC: G07C1/08
Filed: 1959-10-30
Abstract: 907,894. Recording-apparatus. COPE, W. W., and COPE, W. D. Jan. 30, 1961 [Oct. 30, 1959], No. 36821/59. Class 106 (4). In apparatus for recording temperature or stress by means of a stylus 23 on a moving strip 1, the strip is driven through a selected one of several gear trains. The strip 1 is fed forward by a roller 2 whose axle 3 is driven from a shaft 4 by gear-wheels 5, 6 the wheel 6 being connected to the shaft 4 by a ratchet wheel and pawl to allow the strip to be drawn forward when required to tear off a recording thereon. The shaft 4 has secured thereon a pinion 7 connected through suitable gears to gear-wheels 10, 11, 12 mounted loosely on axles 13, 14, 15 and spaced round and meshing with a pinion 9 secured on the shaft 8 of an electric motor. Any one of the gear-wheels 10, 11, 12 can be coupled to its axle 13, 14, 15 by a clutch 16, 17, 18 engaged by energizing an associated solenoid 19, 20, 21. The gear ratios of the different gear trains are chosen so that a given length of strip will be used in different predetermined time periods e.g. the different periods required for sterilizing surgical bandages and other goods. To record which gear ratio has been selected, the strip has corresponding symbols A, B, C marked side by side along one edge and the position of a supplementary stylus is adjusted by the closure of the switch for selecting the gear train to make a line through the corresponding symbol. The stylus 23 may make an ink trace on the strip 1 or it may be electrically heated for recording on heat-sensitive paper. In the latter case three elements 24, 25, 26 in the form of wire loops may be provided the switch for selecting the gear train switching current to the appropriate element. A transparent cursor with a time scale appropriate to each gear train may be provided to facilitate reading the records.

Title: Feed control system for processing equipment
IPC: F26B3/08
Filed: 1971-08-06
Abstract: 1356037 Electric retroactive control of temperature; fluid-pressure servo systems FULLER CO 6 Aug 1971 [27 Aug 1970] 36974/71 Headings G3P and G3R The feed of material to be processed in a termal processing equipment, e.g. a fluidized bed reactor 1 Fig. 1 wherein heat is applied to the material to carry out a chemical reaction or alternatively a fluidized bed cooler, dryer or incinerator, is controlled in dependence upon the deviation in temperature or other characteristic of material 6 (e.g. wetness) within an upper chamber 4 and sensed by thermocouple 100, from a desired value thereof. Air from a blower 8 fluidizes material 6 on a porous grid 2. Processed material is discharged at 12 and unprocessed material is delivered from a hopper 20 via a conduit 44 and entrained in a pressurized air-stream applied at 42. If too much material is being supplied to the reactor 1 the temperature will decrease and vice versa. Thus a temperature error signal produced by a comparator 102 which compares the sensed temperature with a desired temperature, is used to control a reversible motor 105 which actuates a gate (74) Fig. 2 (not shown) in the air supply conduit 44. The amount of restriction imposed by the gate is dependent upon the temperature deviation, as is the pressure differential across the restriction. This pressure differential, which is a measure of the fluid-flow rate, is applied to a diaphragm operated valve 30 which controls the outlet from the hopper 20 and the amount of material entrained accordingly.

Title: Dewatering machine for manufacturing a fibrous web, and method of using the same
IPC: D21F9/00
Filed: 1968-08-02
Abstract: 1,247,013. Papermaking. J. M. VOITH G.m.b.H. 2 Aug., 1968 [2 Aug., 1967], No. 36978/68. Heading D2A. A machine for making a web of fibrous material from a suspension of fibres has a duct from which air can be excluded, and through which the suspension can flow, the duct being delimited on one side by a movable webforming wire, and on the other side converging towards the wire at an angle of 15‹. The duct has individual suction devices or groups of adjoining suction devices, the uppermost region of at least one suction device or at least one group of devices having a vacuum connection with a separating vessel at a pressure lower than that inside the suction device, or group. A device is provided to meter the rate of flow of water through the discharge line from the particular suction device or group, and a throttle with automatic means for varying it as a function of the rate of flow, to keep that rate constant. Several such devices or groups of devices can be controlled in this way, their vacuum connections leading to a common air-separation vessel. The side of the duct away from the wire may be defined by a water-permeable member, e.g. a second wire with its own suction devices or groups of suction devices controlled in the same way, but with the divisions between the devices or groups on one side of the duct staggered with respect to those on the other side. The velocity of the suspension at any point in the duct can thus be held constant, and the velocity profile along the duct can also be held at a desired form, e.g. constant. The invention can be applied to a twin-wire machine (Fig. 3, not shown), a multiple-wire machine with top drainage arrangements (Fig. 5, not shown), a cylinder machine (Fig. 6, not shown) or a rising-wire machine (Fig. 7, not shown). Reference has been directed by the Comptroller to Specification 1,143,604.

Abstract: 1,221,571. Pressure-sensitive copying sheets. CHAMPION PAPER CO. Ltd. 5 Aug., 1968, No. 37261/68. Heading D2B. [Also in Division B8] Transfer sheet materials are produced by coating paper or similar sheet material with an aqueous suspension of a microencapsulated printing ink, particularly colourless lenco dye intermediates, which has been prepared by mixing with brisk agitation on oily solution of the ink, water, and a solution of a hydrophobic, thermoplastic resin in a water- and oilmisci!ble organic solvent from which the resin precipitates on dilution with water so that the resin forms a coating about a nucleus of the oil. Suitable resins, solvents, resin stabilisers and emulsifiers are described in Specification 1,221,489, 37260/68, the emulsifier being added after formation of the microcapsules. A further coating of the same or another resin may be formed by adding a second solution. The inks to be encapsulated are dissolved in oils, e.g. cottonseed, castor, soybean, petroleum lubricating, fish liver, drying or essential oils, methyl salicylate, halogenated biphenyls or low melting fats or waxes, e.g. lard, sperm oil or lanolin; an inhibitor, e.g. N-phenyl 2-naphthylamine may be included, and a buffer material is preferably added to maintain the aqueous phase alkaline. Dispersions of the microencapsulated colourless inks in water with a binder material are applied to one side of paper to form a transfer sheet. The copy sheet is an adsorbent acidic electron-acceptor material so that when dye from the transfer sheet is applied by rupture of the capsules by pressure, the dye is converted to a visible form.

Filed: 1934-12-29
Abstract: Iodoquinine sulphate is prepared by precipitating a solution of quinine sulphate in dilute acetic acid containing a trace of concentrated sulphuric acid with a methyl alcohol solution of iodine. p   Iodocinchonidine sulphate is prepared by precipitating a solution of cinchonidine sulphate in aqueous N-propylalcohol containing a trace of concentrated sulphuric acid with a N-propyl alcohol solution of iodine.ALSO:<PICT:0450090/III/1> A polarizer comprises a supporting body, such as glass, coated without the use of adhesive with a layer of anisotropic material in the form of a single crystal. Suitable anisotropic materials comprise iodoquinine sulphate, iodocinchonidine sulphate, potassium nitrate, potassium bichromate, and iodine.  The single crystal film is deposited from a solution 21 of the anisotropic material contained in a deep seamless glass-lined tank 1 on to spaced vertical supporting plates 9, the level 21 of the solution being slowly lowered with respect to the plates.  This lowering may be accomplished mechanically or by controlled evaporation of the solution.  The depth of plate immersed at starting is preferably one tenth of the depth of liquid in the tank and the angle between the liquid level and supporting surface lies between 0--90 DEG .  The partial pressure of the solvent above the solution, the relative humidity of the atmosphere, temperature, pressure and draught are controlled to aid the deposition.  A temperature of 18--27 DEG  C. at atmospheric pressure are preferred. To prevent deposition of separate crystals the apparatus may be subjected to low amplitude vibration.  The anisotropic layer is coated with a layer of transparent varnish.  Suitable solvents comprise methyl, ethyl, or N-propyl alcohol mixed with water and in accordance with the law of mass action an extraneous substance is added to the solution, e.g. quinine sulphate to the iodoquinine sulphate solution.  The latter salt may be prepared by precipitating a solution of quinine sulphate in dilute acetic acid containing a trace of concentrated sulphuric acid with a methyl alcohol solution of iodine.  Iodocinchonidine sulphate is prepared by precipitating a solution of cinchonidinesulphate in aqueous N-propyl alcohol containing a trace of concentrated sulphuric acid with a N-propyl alcohol solution of iodine.

Abstract: 1516766 Beading foil lids; packaging containers; lids PEERLESS MACHINE & TOOL CORP 9 Sept 1976 [3 Oct 1975] 37428/76 Headings B8C B8D and B8T [Also in Divisions B3 and B5] Material is packaged between a container body and lid both formed from sheet material between male and female dies 20 and 12. Upon full formation of the lid (see Fig. 6) the inner periphery of the edge of the lid and body forming sheets are held fast between surfaces 18 and 34 of the female die and a piston 22 by which the male die is reciprocated respectively. The outer periphery of the sheets is deformed to make a tubular sleeve located between the outer surface of the female die and the inner surfaces of a pair of draw pads 52, 80. The draw pads together define an annular void 90. From this position the draw pads are moved upwardly relative to dies and the piston to cause the free end of the tubular sleeve to be engaged by an upwardly and outwardly sloping frustoconical surface 92 of the lower pad. Consequently the sleeve is buckled outwardly into the void 90 (see Fig. 7) to form a ring to seal the lid to the body of the container. In another embodiment, (see Fig. 4) the edge of a single sheet (102), drawn to form a lid or a container body, is similarly buckled to form a ring 118, which in the case of a lid forms a snapring enabling the lid to be attached to a container body.

In a television receiver in which the frame synchronizing pulse is separated from the composite synchronizing pulse train by an integrator circuit 1-4 and applied via an amplifier stage 7 to synchronize the frame blocking oscillator 23, the anode circuit of the amplifier includes a resonant circuit 8, 9, tuned to a frequency, e.g. 300 c/s., considerably higher than the frame frequency, and a damping circuit comprising a diode 10 and resistor 11 is connected across the tuned circuit, the pulse train generated in the resonant circuit and appearing at the junction of the diode and resistor being applied to synchronize the oscillator. A capacitor 20 serves to integrate the pulse train. Interaction between the frame oscillator and separator stage is avoided by applying the pulse train to the anode of the oscillator valve through a resistor 21 and capacitor 22. Amplifier 7 is operated with a short grid base characteristic, so as to limit the input signal excursions and thereby eliminate interference, by returning the grid to a positive potential via resistor 16 and providing a low screen voltage by way of potential divider 18, 19. A switch or relay circuit may be provided to reverse the connections to diode 10 to allow for operation with received signals bearing either positive or negative modulation.
