Title: Automatic control system for moulding presses
IPC: B30B11/00
Filed: 1965-11-24
Abstract: 1,127,647. Automatic control of moulding. LAEIS-WERKE A.G. Nov. 24, 1965 [Nov. 28, 1964], No.49984/65. Heading G3R. [Also in Division B5] In a system for press-moulding a succession of articles, the magnitude of the error in volume, height or ram pressure for each article relative to a desired value is measured and utilized to effect corresponding correction for the next article automatically. In Fig. 1, a brick 4 is formed in a moulding press actuated by a piston 2, travel of which is terminated when the fluid-pressure behind it reaches a value at which a pressureresponsive switch 16 closes a valve 24 to cut off the supply of fluid. The length of the brick so formed is measured by a potentiometer 26 detecting relative movement between the two ends of the press and any deviation of this length from a desired length is effective through an electrical follow-up controller 31 to operate a motor 12 adjusting the position of a back stop 11 for piston 2 so that the volume of material supplied for the next brick results in a brick of the desired size. In a modification, Fig. 2 (not shown), movement of the piston is terminated by a switch which operates when the length of the brick reaches a desired value, and a potentiometer, operated by the fluid-pressure which is then applied, controls the setting of the back stop so that the next brick has the desired density. Use of both length and pressure signals, which are combined electrically by a bridge circuit, or mechanically, to effect correction, is referred to. In order to allow for the compressibility of the moulding material, a potentiometer operated by a roller pressing on a stream of the material is associated with a bridge circuit which is periodically balanced and connected to the main control circuit to modify the control. Use of induction, capacity, magnetic or radiation type detectors in place of potentiometers is referred to. Correction may be effected by varying the weight or rate of feed of the moulding material instead of adjusting the piston back stop. The moulding machine may be of the vibrating type.

Title: Insulating tape for the windings of electrical machines
Inventor: KOECHLIN PAUL
IPC: H01B3/48
Filed: 1964-12-09
Abstract: An electrical insulating tape comprises a supporting material of synthetic fibre impregnated with a synthetic resin without solvent e.g. as a dust, or low viscosity resin, and coated on one or both sides with a layer of a thermohardening synthetic resin applied in the form of a fine powder which is melted on the surface of the tape. The impregnating resin may be an epoxy, a polyester, or an ethoxyline resin.  The thermohardening resin may be an epoxy resin containing a hardening agent, or a phenol-aldehyde or urea-aldehyde resin.  The supporting material may be a tissue of glass fibre cut on the bias, a tissue of polyester fibre, a tissue having glass warp fibres and polyester wool fibres, or a felt tape of polyester fibres which may be oriented or reinforced by a continuous thread of the same material as the fibres of the felt in order to give mechanical resistance in the direction of the length of the tape.  The powder may be applied to the tape by powdering over it, by projection from a gun, or by passing through a fluid bath.  A film of polyethylene terephthalate may be stuck to one side of the tape immediately after melting the layer of powder.

Title: Improvements in or relating to variable speed controls
IPC: H02P25/14
Filed: 1969-10-14
Abstract: 1286989 Automatic control of speed ACIERS ET OUTILLAGE PEUGEOT 14 Oct 1969 [12 Nov 1968] 50444/69 Heading G3R [Also in Division H2] The speed of a motor M (a series wound, commutater type) is kept constant by controlling the firing angle of a series connected triac T1 in response to the back e.m.f. The triac is triggered when the voltage on a capacitor C1 is sufficient to cause a diac D1 to conduct; C1 is charged from the A.C. supply via R1 and speed setting potentiometers P1, P2 but it is shunted by a transistor T2 whose conduction increases with increasing value of the back e. m.f., applied across its base/emitter via R3, thereby delaying charging of C1 and hence the firing of T1. Resistors R2, R4 determine the effectiveness of the shunt circuit and diodes D2, D3 protect T2.

Abstract: 1316468 Hand-knitting L D GILCHRIST 26 Oct 1970 [12 Nov 1969] 50710/70 Heading D1K In a method of hand knitting stitches are cast onto a first needle by placing a loop on the needle, working through it with a second needle and transferring the thus formed loop to the first needle. Stitches are worked through the pair of loops nearest the point of the needle-initially the only two loops on the needle-and the worked stitch transferred at each step. Knitting of the garment proceeds with courses formed by inserting one pin through at least two stitches on the other, and drawing a loop through all of them. The worked stitch nearest the point is removed. Each will thus be knitted through at least twice. The stitches may be worked as plain or purl, and into the front or back of the stitches. Increasing and decreasing may be effected by removing one fewer or one more stitch respectively.

Title: Improvements in or relating to Silver Halide Photographic Emulsions
IPC: G03C1/42
Filed: 1968-10-25
Abstract: 1,184,138. Sensitized silver halide photographic emulsion. CHEMISCHES LABORATORIUM FRITZ-WALTER LANGE. G. m. b. H. Oct.25, 1968 [Nov. 3, 1967], No. 50782/68. Heading G2C. The invention comprises a silver halide photographic emulsion containing, as a sensitizer, gold (I) mercapto glucose having the formula I: The emulsion preferably contains 1À5 mg. to 150 mg. of sensitizer per g. atom of silver. This emulsion may be prepared by precipitating the silver halide in the presence of gelatine by reaction of a water-soluble halide with aqueous silver nitrate, ripening the emulsion and chilling to set the emulsion, washing and remelting the emulsion and adding the sensitizer during a second, chemical ripening stage. Gold (I) mercapto glucose in the emulsion during the chemical ripening stage produces a substantial increase in sensitivity with extremely little fogging; it does not form an insoluble compound with hydroquinone and can therefore be used in emulsions containing hydroquinone as a developing agent; it does not form an insoluble product with silver chloride and can therefore be used in silver chloride emulsions; and there is no fading of the latent image in the exposed emulsion as there is with the gold rhodanide complex.

Title: Process and apparatus for controlling carbon residue content of oil
Inventor: COGGESHALL NORMAN DAVID
IPC: C10G7/12
Filed: 1963-12-27
Abstract: 1,068,327. Controlling hydrocarbon cracking. GULF RESEARCH & DEVELOPMENT CO. Dec. 27, 1963, No. 51072/63. Heading B1X, [Also in Division G1] Determination of the absorption by a petroleum product of light in a particular band, is sued to determine the carbon residue content of the product and to control operations in a catalytic cracker. Thus the transmitted light may be used to control a process for stabilizing the carbon residue content to a particular value in oil refining operations, or alternatively to control the regeneration of the catalyst, by varying the temperature, duration or amount of regeneration air used to bum the coke off the catalyst. In a method of controlling the cracker as shown in Fig. 3 the output 54 from the cracker is mixed with naphtha in proportioning pump 62 and submitted to spectrometric analysis by apparatus 68 which feeds a recorder-controller 72. The latter controls the valve 10 supplying the fuel to the heater 6 to vary the temperature of the mixture applied to the flash zone 14 of the cracker. Alternatively. the controller 72 may operate on valve 78, as that if the carbon residue is shown to be too high the valve is moved to a more closed position to increase the amount of recycled oil. Thus the amount of lower boiling point oil flowing downwardly to tray 18 increases and as some of this is recycled via line 48 more of this oil appears in the input to the cracker, so reducing the carbon residue. Calibration details for correlating absorption against carbon residues are given.

Abstract: 1,088,960. Regulating fluid flow. G. BURATTI. Dec. 22, 1964 [Jan. 4, 1964], No.51969/64. Heading G3H. [Also in Divisions F2 and G4/6] A diaphragm 2 (Fig. 2) is rotated on a central shaft 1 according to an input analog signal so that certain passages 5, 7, 8 in the diaphragm lie between pairs of lower blowing nozzles and upper receiving nozzles 4, a digital output being obtained from those upper nozzles which receive fluid under pressure from the blowing nozzles. In the form shown, for a decimal system of digital coding, holes 5 on an outer circumference of the diaphragm 2 represent the units from 0 to 9, slots 7 on the middle circumference represent the tens from 10 to 50 inclusive and slots 8 on an inner circumference the tens from 60 to 90. The passages are so positioned that the nozzles 4 may only simultaneously overlie one passage on each circumference. A pawl 19 meshing with teeth 18 of the diaphragm 2 prevents the diaphragm from taking up an intermediate position between two units. Each receiving nozzle is preferably connected to a two input logical circuit device in which a ball 63 (Fig. 5) can shut off one input so that flow from the other is directed to the output device. For values over 100 a similar device with three inputs may be used. Alternatively each input 62 (Fig. 7) may be directed into a chamber 64 bounded by a diaphragm 65 which when displaced against the action of a spring 66 raises a plug 67 to connect the output duct to a fluid source 68. Cams 39, 40 (Fig.4) are positioned on a rotating shaft 42 so that fluid is first allowed to flow through the slots 7, 8 by opening a valve 31 and then through the holes 5 by opening a valve 32 so that the keys of a pneumatically operated typewriter corresponding to the tens are operated before those corresponding to the units.

Abstract: 1,095,707. Pulse delaying circuits. FUJITSU Ltd. Dec. 24, 1964 [Dec. 28, 1963], No. 52487/64. Heading H3T. In a circuit for increasing the separation between too-closely spaced pulses, all pulses are delayed by a delay time control circuit 15, a further circuit (such as 13, 18, 23) being provided for increasing the delay applied to the second of two closely spaced pulses. As described, a monostable multivibrator 13 is triggered by an input pulse at 11, providing a longer duration output pulse at 21, enabling AND gate 18. If the next pulse at 11 occurs during the unstable period of 13, it is passed by AND gate 18 to set the bi-stable circuit 23, the output of which increases the delay imposed on the second pulse by a further monostable circuit 15. The invention is applicable to counting systems. Adjustable-duration monostable circuits.-Fig. 3 shows a circuit for use in block 15. Each input ulse at 17 is differentiated at 22 and turns off transistor 28, turning on transistor 29 for a time dependent on the charging time of 'capacitor 35. This is normally limited by attaching diodes 46, 52 to the potential at the junction of resistors 48, 49, but is limited to a lower potential (greater operating time) when diode 44 is turned on by operation of circuit 23 (Fig. 2). The pulses at the collector of 28 are differentiated at 56, so that output pulses are available at 12, corresponding to the trailing edge, being delayed by a time dependent on the state of bi-stable circuit 23.
