IPC: H03F3/40
Filed: 1971-05-05
Abstract: 1283172 Amplifiers IWASAKI TSUSHINKI KK 5 May 1971 [13 May 1970] 13323/71 Heading H3W In a direct-current amplifying arrangement signal is applied from terminal 1 over a switch 2 with an alternative earth position to the input of a direct-current amplifier 7. The output of amplifier 7 is applied to the out-of-phase input 8 of a differential amplifier which applies an output to the terminal 11. This output is applied to charge a capacitor 16 over switch 15 which is closed when the switch 2 is on earth position, so that the capacitor 16 is charged up to provide an input to the in-phase input terminal 9 which compensates for drift in the system. A further amplifier (13) may be included in the feedback path, either between the output terminal 11 and switch 15 (Fig. 1, not shown) or alternatively between capacitor 16 and the amplifier input terminal 9 (Fig. 3, not shown).
Patent GB-133357-A (GB)
IPC: F42C15/22
Abstract: 133,357. Semple, J. B. March 27, 1918, [Convention date]. Projectile fuses.-Relates to devices for preventing premature explosion of the charge in a projectile, and consists in the provision of a continuous train of detonation-transmitting material leading from the detonator to the bursting-charge, which train includes an unconfined section at a point where the direction of the train changes. In the fuse shown, a train 6, 7 leads from the detonator chamber to a chares 4, which may be regarded as part of the bursting-charge 3 of the projectile. At the point 8 where the direction of the train changes, it is practically unconfined, although a thin protective disk 9 may be provided. The detonator 5 is in a longitudinally movable carrier 10 which is normally held in the position shown by a centrifugal bolt 11 arranged in an oblique runway for the purpose described in Specification 133,356, and retained by a resilient inertia-ring 12. The bolt 11 escapes during the flight of the projectile, and, on impact, a hammer 14 is driven in directly, shearing a pin 15, forcing the detonator-carrier to the bottom of its chamber, and finally being driven in farther so as to ignite a percussion cap 13 and thereby fire the detonator. On account of the construction of the train 6, 7, a premature explosion of the detonator when in the position shown in Fig. 1 would merely explode or blow out the material in the channel 6; when, however, the detonator is exploded in its innermost position, the detonation is transmitted throughout the train 6, 7 to the charge 4.

Title: Voltage to pulse rate converter
IPC: H03M1/00
Filed: 1959-04-20
Abstract: 898,471. Voltage measuring. HEWLETTPACKARD CO. April 20, 1959 [April 28, 1958], No. 13452/59. Class 37. In a voltage to pulse rate converter, a pulse train output is provided, the pulse rate of which varies in accordance with the magnitude of a D.C. voltage input signal. The input signal at terminal 11 is applied through resistor 12 to a high-gain D.C. amplifier 14, having a capacitor 17 in shunt; the amplifier output feeds a pulseforming circuit 18, and feedback line 21 connects the output of circuit 18 to the amplifier input 13. The pulse forming circuit 18 generates a constant energy pulse whenever the input voltage thereto reaches a predetermined value; and this pulse, having opposite polarity to that of the input signal, is applied to the amplifier input whereby the charge on capacitor 17 is reduced by a constant amount corresponding to the fixed energy content of the pulse. The subsequent rate of charge of capacitor 17, and hence the time interval before the next pulse is produced by circuit 18, will be dependent upon the magnitude of the input signal. Thus a pulse train is provided at terminal 20, the rate of which is dependent upon the magnitude of the input signal.

Abstract: 784,589. Fuel injection pumps. C.A.V., Ltd. April 27, 1956 [May 13, 1955], No. 13854/55. Class 102(1). In a fuel injection pump for internal combustion engines of the type where fuel is fed from a feed pump to an injection pump, the two plungers of the injection pump are reciprocated by a cam so that the injection rate of the fuel varies. The cam c has equally spaced lobes f. Between the lobes are formed two shallow recesses g and two deeper recesses h. The body containing the plungers rotates in the direction of the arrow and the inward movement of the plunger in contact with the shallow recess g commences at i and the movement of the plunger in the deeper recess h commences at j. The latter point j is angularly in advance of i and consequently the plunger having the longer stroke commences its inward movement earlier than the other. In a modification the recesses are of the same depth but two adjacent lobes are retarded relative to the other two. The number of plungers or lobes may be varied to suit the number of cylinders in the engine and the cam may be angularly adjustable.

Title: Production of an improved acrylonitrile polymer yarn
IPC: D01D10/04
Filed: 1944-07-28
Abstract: <PICT:0585367/IV/1> An acrylonitrile polymer yarn, film, tubing, fibre, or similar article which has been treated, e.g. stretched so that it has a pronounced oriented micellar structure is heated in relaxed state to a temperature of at least 80 DEG  C. until it has substantially ceased to shrink and is then maintained at a temperature of at least 80 DEG  C. for 1 to 24 hours in relaxed state or under such a p  low tension that there is substantially no stretching.  The heat treatment may be effected in air or in an atmosphere of an inert gas or in an inert liquid.  The treatment improves the tenacity and elongation of the yarn or other article. The degree of orientation of the yarn to be treated is at least equal to that obtained by stretching a dry spun yarn of the polymer and subsequently stretching it to twice its original length while passing through glycerol at 130 DEG  C.  The initial heating in relaxed state causes the yarn to shrink 10-25 per cent of its length.  The second step involving a prolonged heating of the shrunken yarn produces an increase in tenancity without loss of elongation.  The acrylonitrile polymer may have a molecular weight of 7,000 to 400,000.  It may be a simple polymer or an interpolymer of acrylonitrile and a vinyl compound, an olefinic compound, or an unsaturated carboxylic acid, provided that such an interpolymer contains a major portion of acrylonitrile As shown in Fig. 1, the acrylonitrile polymer yarn 1 is unwound at constant weight from bobbin 2 by roller 3 and is led through the heating device 5 by roller 6.  The roller speeds are adjusted to that the yarn is heated in relaxed state.  The yarn is wound on to a bobbin under low tension and the wound package is placed in an oven at 80 DEG  C. or more for at least 1 hour.  As shown in Fig. 2, the heating device comprises a solid block provided with a slot 21 through which the yarn 1 is led and a bore 22 in which is placed an electrical resistance 23.  In an example, a solution of acrylonitrile polymer in tetramethylene cyclic sulphone is dry spun and the yarn obtained is stretched between rollers and while passing over a heated pin to 8 times its original length.  The yarn is then passed through a slot in a heated metal block while free to shrink, and after collection under low tension on a bobbin it is heated at 150 DEG  C. for 1 hour.  In another example, a solution of acrylonitrile polymer in dimethyl formamide is extruded into hot glycerine.  The yarn obtained is wound into skeins and suspended in relaxed condition for at least 1 hour in glycerine at 100 DEG  C. Specifications 579,887, 583,939 and 585,368 are referred to.
