Title: Improvements relating to the manufacture of water gas
IPC: C10J3/00
Filed: 1932-04-20
Abstract: 391,603. Water-gas generators. HUMPHREYS & GLASGOW, Ltd. and GLASGOW, A. G., Humglas House, Carlisle Place, London. April 20, 1932, No. 11369. [Class 55 (i).] In the production of water gas, wherein the blast gases are used to store heat in recuperative chambers, and for steam production, the amount of steam produced is regulated by varying during back-running the point or points of steam admission so that the steam recovers none or a varying amount of the stored heat before entering the generator. Blast gases from a generator a are used to heat a carburetter b, superheater c and steam boiler d, primary air being admitted by a pipe e, and secondary air to the chambers b, c and d. Steam is admitted from a main l through branches m, n and o each having a separate valve, so that the amounts of steam supplied by each branch may be controlled, and all the steam for a down run may be admitted through any one of two branches. A suitable steam control, Fig. 2, comprises a pair of valves 4, 5 on a common stem 6, by movement of which one valve is completely closed when the other is open, and both branches n and o may be put in communication with the steam supply, the proportion of steam passing to each being regulated.

Title: Improvements in or relating to circuit arrangements for checking variations in the thickness or mass of textile threads
IPC: B65H63/06
Filed: 1965-03-22
Abstract: 1,103,474. Detecting faults in yarn electrically. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 22, 1965 [March 25, 1964], No. 11991/65. Headings G1A and G1N. An output signal V 1  from a slub detector (not shown) e.g. capacitive or photo-electric, is fed to an amplifier V having a load resistance R b  (Fig. 2), which may be a heating element in thermal engagement with two N. T. C. resistors R 2 , R 4 , or it may be a lamp co-operating with cadmium sulphide photo-electric resistors. A voltage V u  is applied to a relay (not shown) which co-operates with a cutter to cut the thread or operate a counter if a slub e.g. in excess of double the mean mass/ cm length of normal thread, is detected. The amplifier load R b  causes the amplifier output signal V u  to be a function of gradual variations of the input V 1  and forms a so called "slow control." Because of thermal inertia however, rapid variations in V 1  due to the appearance of a slub will not cause a corresponding variation in the heat or light transmission from R b  to resistors R 2  and R 4 , so that the output V u  will vary rapidly causing operation of the cutter. The amplifier has a constant output for a wide range of thread thickness between A and B on curve Fig. 1. When no thread is present at the detector, for a period during a tying operation, the amplification factor will increase to a high value so that the relay and cutter would be caused to operate immediately a thread is inserted. To prevent this, in Fig. 3 (not shown) the amplifier is provided with a positive feedback coupling including an L. C. circuit whereby the amplifier is caused to oscillate when a thread is removed for tying, the amplifier being switched from one state to another by a Schmidt trigger.

Title: Improvements in the production of mono-filaments
IPC: D01F6/08
Filed: 1942-08-26
Abstract: A bundle of thermoplastic vinyl resin filaments, which have been stretched in excess of 50 per cent of their original length and twisted is converted into a monofil by coalescing the constituent filaments by heating while preventing longitudinal contraction of the bundle.  Coalescence may be partial or complete.  The vinyl resin may be a copolymer of vinyl acetate and vinyl chloride, a chlorinated copolymer of vinyl acetate and vinyl chloride, polyvinyl chloride, or a chlorinated polyvinyl chloride.  The bundle of filaments may be in the form of a tow, a continuous filament yarn, or plied yarns, e.g. a cord.  Heat may be applied by means of a fluid, e.g. hot air, live steam whether wet, saturated, or superheated hot glycerine, or hot ethylene glycol.  The bundle may be treated while it is wound on a spool or bobbin, or is in a similar package form, and fusion of the constituent filaments of the bundle may be effected without adhesion of the several convolutions of the bundle.  Monofils of circular or other cross-section may be obtained.  They may be used in the production of hosiery, tennis-racket strings, bristles, violin strings, or artificial horsehair.

Abstract: 864,582. Kinematograph projectors; synchronizing with tape recorders. SPECTO Ltd. April 14, 1958 [April 12, 1957], No. 12019/57. Class 40 (2). [Also in Groups XX and XXXV] To enable the speed of projection of a kinematograph film to be maintained substantially in step with a separately-driven tape recorder providing pre-recorded associated sound, a projector comprises an electric driving-motor, centrifugally operated contacts for maintaining the speed of said motor substantially constant, and a three-state electric switch means manually operable from a normal state in which said constant speed is maintained to each of two other states in which said means is effective respectively to increase or decrease said speed. In the embodiment shown, the projector shaft is driven by an electric motor 10 and is controlled by a switch 13. The speed is kept constant by a centrifugal speed governor 16 which is bridged across the resistance 12 and switch 14 and is in parallel with capacitance 18 and resistance 17. The motor speed can be temporarily increased by closing switch 14, which is in series with the motor, and adjusting the resistance 12. To decrease the speed temporarily switch 15 is opened, thereby including the variable resistance 17 in the circuit. The switches 15, 14, which may be push-buttons, are biased to a position corresponding to the motor's constant speed.

Abstract: 559,753. Sealing electric lamps &c. MARCONT"S WIRELESS TELEGRAPH CO., Ltd., Aug. 28, 1942, No. 12115. Convention date, Jan. 31, 1941. [Class 39 (ii)] [Also in Group XL] A device for exhausting and sealing an envelope 1 having an exhaust tube 2a includes a plate 4 supporting the envelope and having a port through which the exhaust tube passes with heating means 9 in the plate around the port. When these means, which may be an electric heating resistance are energised the exhaust tube becomes heated and collapses and when the plate 4 is-raised by a plunger 12, the tube 2a is severed and the envelope sealed off. The lower part of the tube remains in the rubber block 14 which serves as the seal connecting the tube 2a to the exhaust pump tube 15 until expelled by an electromagnetically operated plunger within this latter tube 15. Cooling air is passed through a chamber 21 above the plate 4 in order to prevent the heat of the sealing operations harming the envelope 1 and the connections in its lower part. The top of this chamber 21 is covered by pivoted lids provided with a notch each, which under spring pressure swing together to hold the envelope 1 and seal the top of chamber 21. The electrodes in the envelope may be provided with leads 3 passing through further ports in the plate 4 into contact with fingers 8 and thus may be energized to de-gas them during exhaustion.

IPC: F04B9/14
Filed: 1967-03-15
Abstract: 1,209,182. Syringes. PYE Ltd. March 14, 1968 [March 15, 1967], No. 12122/67. Heading F1R. An injector for injecting measured microquantities of liquid samples into chromatographic equipment, comprising a sampling tube 1, Fig. 2, with a close-fitting wire-like plunger 6 therein, has means for substantially preventing rotation of the plunger in a gland 7 at one end of the sampling tube. The rotation may be prevented by a tube 9 co-operating with members 8, 10 fixed to the plunger and sampling tube respectively, or by making the co-operating surfaces of tubes 3 and 5 of non-circular cross-section, e. g. hexagonal. A screw 11 prevents accidental withdrawal of the plunger from the sampling tube. A resilient scale member 12, Fig. 4, is locked by a finger screw (not shown) in a channel in the member 8 in a position corresponding to the volume of sample required, and normally rests on the side of the member 10. However, during filling of the sampling tube, the scale member moves clear of the member 10, See Fig. 4, and can therefore be flexed into a position in which, on subsequent movement of the members 8 and 10 towards one another, the bottom of the scale member will abut the top of member 10. Thus the required volume of sample in left in the sampling tube and can be discharged therefrom when the scale is released from its flexed position. In an alternative embodiment, Fig.5 (not shown), the scale member is located in slots in both members (8 and 10), and the lower end of the scale is bent inwardly below the member (10) to form an abutment (15) which, after locking of the scale in its required position to the member (8) and during filling of the sampling tube, contacts the bottom of the member (10) to prevent further filling when the sampling tube contains the required sample volume. The injector may have a compression spring surrounding the tube 9 between the member 8, 10, have finger grips, and be made wholly of metal.
