Abstract: 1353685 Lamp failure alarms PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 May 1971 [29 May 1970] 17239/71 Heading G4N In a circuit for supervising a load (such as the flashing lamps 1 of a motor vehicle) which is fed with direct current, interrupted by contacts 3, the contacts are bridged by the series arrangement of a capacitor 6 and resistor 5, the voltage across resistor 5 being supplied to a transistor amplifier 13 arranged to provide a signal in the event of a fault in load 1. At the onset of each break of contacts 3, the voltage across resistor 5 reaches a maximum as capacitor 6 begins to charge, the maximum value being a function of the potential division between the resistor 5 and the resistance of the load 1. Under normal conditions, the differential amplifier 13 will produce an output such as to maintain the control circuit 7 for the flashing relay 9 at ninety times per minute but if one of lamps 1 should fail, the amplifier 13 produces no output so that the flashing rate is doubled. Alternatively, a pilot lamp may be connected in series with the collector of one of the transistors of amplifier 13. Diodes and transistors may be connected across resistors 11 and/or 12 to compensate for changes in voltage of battery U. In Fig. 1 (not shown) amplifier 13 is formed by a single transistor, components 14, 19, 21 being omitted.

Title: Improvements in apparatus for extruding metal
IPC: B21C23/30
Filed: 1937-06-23
Abstract: 495,891. Squirting. BEAVER, C. J., FAIRFIELD, T. J., and GLOVER & CO., Ltd., W. T. June 23, 1937, No. 17478. [Class 83 (iv)] In apparatus for extruding plastic metal from two or more containers in which plungers operate successively at time intervals to produce a continuous output, a valveless passage leads from each container to a common extrusion chamber and back flow of metal is prevented by arranging the junctions between any two passages or between a passage and the chamber so that there is an angle of 90‹ or less between any two meeting streams of metal. The invention is shown applied to an apparatus for extruding a metal sheath 1 around a cable 2. The metal is forced into the extrusion chamber 21 alternately from containers 3 and 4 by means of rams 8, each of the containers communicating with the chamber 21 by two passages 17, 18 and 19, 20 respectively. In order to prevent back flow of metal into one container during the back stroke of the ram in that container and during the pressure stroke of the ram in the other container, the passages 17 and 19 and the passages 18 and 20 meet at an angle of 60‹. In a modified form the metal streams 32, 34 from the two containers pass directly into the extrusion chamber in a tangential direction. Specification 479,971 is referred to.

Abstract: 622,199. Valve generating circuits. SPERRY GYROSCOPE CO., Inc. July 9, 1945, No. 17518. Convention date, July 8, 1944. [Class 40 (vi)] A sawtooth generator comprises an intermittent discharge device connected across a condenser in series with a charging resistor, the linear sweep voltage output being produced across the common cathode resistance of a pair of discharge tubes connected so as to maintain a constant potential difference across a portion of the charging resistor to provide a constant charging current. In the Figure, discharge valve 12 is cut off intermittently by negative pulses applied to point 25, and condenser 11 then charges through resistance 15. The output of a unity gain amplifier comprising valves 28 and 29 is connected to a fixed point 16 on resistance 15 so as to maintain a constant potential difference across the lower part of resistance 15, and thus provide a constant charging current for condenser 11 to linearise the sawtooth waveform. The output voltage is taken from across the cathode resistance 31. A modification is described in which discharge valve 12 is replaced by a self-running multivibrator arrangement, the cathode of valve 29 is connected through an additional resistance to an adjustable tapping on resistance 31 to provide a gain control. Reference has been directed by the Comptroller to Specification 547,949.
Patent GB-182131-A (GB)
Title: Improvements in and connected with winches
IPC: B66D1/14
Filed: 1922-06-26
Abstract: 182,131. Nederlandsche Fabriek van Werktuigen en Spoorwegmaterieel Genaamd Werkspoor. June 25, 1921, [Convention date]. Winches ; driving-gear. - Driving- gear for winches is constructed so that by the manipulation of two disc clutches, the load is hoisted and lowered under brake control without the possibility of overrunning the driving-shaft, while light loads or the unloaded hook can readily be lowered by a positive drive. In the illustrated form, Figs. 1 and 2 are views of the right and left handed portions of the winch respectively. The driving-shaft 1 rotates constantly in the same direction. For hoisting, a sleeve 17 is moved towards the left by a lever 18 to engage the members of the disc clutch 20, thus driving the sleeve 23 which carries the drum 22. When the clutch 20 is disengaged again, the load can be held by a manually-applied brake acting on a drum 31. By applying the clutch lightly, it can be used as a brake when lowering moderate loads by gravity, such that there is no danger involved in their overrunning. For lowering the unloaded hook with a positive downward drive, the sleeve 17 is moved to the right to engage the members of the disc clutch 19. This connects a sleeve carrying the pinion 3 directly to the driving-shaft, and transmits a reversed drive to the drum through the countershaft 27. For controlled lowering of a heavy load, the sleeve 17 is brought back to mid-position after hoisting. The falling load drives the pinion 3 and the attached casing of the clutch 19 in the same direction as the driving-shaft. When the casing overruns the driving-shaft, a ring 7 rotating with the casing rotates a nut 5 by friction at a greater speed than the shaft, thereby overcoming the tendency of the screw 11 on the shaft to keep the nut against a stop 12, and thus moving the nut towards the left until projections 4, 6 on the casing and nut interengage and effect a quick positive drive of the nut towards the left to engage the clutch and lock the casing to the driving-shaft to prevent further overrunning of the load.

A device for smoothing the lateral edges of zip-fastener members which are clamped on a band of material includes two parallel opposed transport cylinders formed with screw-thread shaped grooves which engage said edges and which have no pitch over part of each circumferential turn, and a freely rotatable smoothing roller mounted eccentrically on or in each transport cylinder so as to roll on a fastener member edge while the fastener members are stationary in the no-pitch parts of the grooves. Fastener members 2 are clamped by means 3, 4 on a band 1 of material, the fasteners on the band being then engaged by generally helical grooves 6 on parallel rotated cylinders 5 and guided by a bar 12, Fig. 3 (not shown). These grooves have a part 6a extending over 90- 120 degrees of each turn with a pitch equal to the distance between adjacent fastener elements 2 or to a multiple thereof and a part 6b extending 270-240 degrees of each turn with zero pitch, so that the elements 2 on the band are advanced when engaged by the part 6a and are stationary, for smoothing thereof to be effected and to hold the band 1 while the elements 2 are clamped thereon, when engaged by the part 6b. A smoothing roller 7, channelled at 10 and freely rotatable on a pivot 8, is mounted eccentrically within each cylinder 5 and projects through slots 11 in the groove parts 6b thereof so as to engage and smooth the lateral edges of the fastener members 2 when they are stationary. The eccentricity of the rollers 7 may be adjusted and several rollers 7 may be arranged one behind the other on each pivot 8 or be joined into one smoothing roller. In another embodiment, Fig. 6, with the shaft ends of the cylinders 5 supported in bearings 5a, 5b, smoothing rollers 7 are mounted eccentrically on the upper end face of the cylinders 5. These rollers 7 may be wide enough to overlap two elements 2 and each be formed with two grooves, the first, 7a, Fig. 8, being shaped to provide a preliminary smoothing and the second, 7b, to provide the final smoothing. In this embodiment, further smoothing discs may be arranged next to the smoothing rollers 7 but inside the cylinders 5. Reference has been directed by the Comptroller to Specification 672,615.

Title: Improvements in and relating to the production of a horse hair substitute, particularly for stuffing purposes
IPC: D01C1/02
Filed: 1930-06-06
Abstract: A horsehair substitute suitable for stuffing purposes is produced from hard vegetable fibres such as coco nut or agave fibres, which have been freed from embedding substances by treating with alkaline lye of less than 10 per cent strength at a temperature below 100 DEG C.  The fibres are treated for such a time that the hard encrusting materials are removed without great loss of fibre, for example, 2-3 hours with a 2-3 per cent soda lye at 80-95 DEG  C.  The fibres are preferably subsequently treated with a hygroscopic material such as glycerine or magnesium chloride, also, or alternatively, with fatty or oily substances such as emulsions of fatty acids, the softness and elasticity of the fibres being thereby enhanced.  finally, the fibres may be dyed and used alone or with other suitable material, such as animal hair, for stuffing purposes.

Abstract: 463,229. Rock - drill valve gear. INGERSOLL-RAND CO. June 29, 1936, No. 17975. Convention date, July 19,1935. [Class 122 (ii)] The fluid supply to the cylinder of a fluidactuated rock drill is controlled by a differential slide valve with areas alternately put into communication with the cylinder and with the exhaust to reciprocate the piston. The valve has opposed, differential, holding-surfaces which control the supply of fluid to the ends of the piston, and are constantly in communication with the respective ends of the piston chamber. The distributing-valve 47 is arranged around a sleeve through which passes the rifle bar 38 connected to the ratchet mechanism at the rear of the tool. The back head 31 has a supply reservoir 37 and the main exhaust 24 is controlled by the piston 23. The valve -chest comprises a pair of plates 42, 43 with extensions 44, 45 adapted to form a chest 46 for the valve 47. A supply passage 50 opens into annular grooves 51, 52 from which pressure fluid passes to the ends of the cylinder chamber. The valve has a rear reduced portion 53 and a front enlarged portion 54 connected by lateral walls 55 with front and rear actuating-faces 56, 57 to which fluid is transferred from the cylinder through kicker passages 59, 58 arranged on each side of the port 24. The faces 56, 57 have atmospheric vents 60, 61. The portion 54 reciprocates in a groove 62 and controls the admission of pressure fluid to the rear ports 63. The front end 18 constitutes a holding-surface. Similarly the ports 53 controls the supply to the passage 65 and has a holding-area 19. A groove 66 in the portion 53 defines a restricted-flow area. The valve has an inner pressure surface 68 to facilitate starting. A leak port 70 permits fluid to pass to the front inlet 65 to move the piston rearwardly and start the valve operation. Seating surfaces determine the limiting positions of the valve. Compression also assists in actuating the valve.
