Title: Improvements in and relating to means for feeding ammunition to automatic guns
IPC: F41A9/49
Filed: 1944-08-19
Abstract: 739,039. Ammunition feed mechanism. WOODHOUSE, C. H. L., and WEBSTER, T. H. July 27,1945 [Aug. 19, 1944], No. 15880/44. Classes 92(1) and 92(2). In an automatic gun having a magazine 1 containing clips of cartridges 2 on an endless conveyer, means are provided for storing energy from a single recoil of the gun barrel and for releasing this energy after a given number of succeeding recoils in order to advance the conveyer by an amount sufficient to bring a fresh clip into the loading position. Upon each recoil, in the construction shown, the loading tray T rocks a lever A which, by the levers, links and shafts D. E. F. I. G. and L. shown in Figs. 1 and 2, rocks a shaft M ; a spring S connected to an arm K<SP>1</SP> of shaft M returns the links and levers to the initial position when the tray T moves forwards. An arm O, Figs. 2 and 9, on the shaft M has a nose P which is adapted to engage with a tooth U on a disc Q keyed to a shaft R which is co-axial with shaft M and is carried by brackets h on the magazine 1. By this means the rocking of shaft M by the tray T serves to rock the shaft R from the position shown in Fig. 9 to a position in which a tooth U<SP>1</SP> on the disc Q is held by the nose a of a toggle-mechanism, thus preventing anti-clockwise movement of the shaft R under the action of springs S<SP>1</SP>, S2 (see Fig. 3). With the shaft R thus held, the shaft M rocks idly under the action of the tray T during the firing of the next few rounds. When, however, the last cartridge 2 from the clip is fed to the gun feeler fingers 44, Figs. 1 and 2, which were resting against the rounds are freed thereby enabling a spring s to move downwards a rod y which, by cranks v, w, move to the right a link f carrying the togglemechanism. The toggle-joint is thereby broken and the shaft R rotates anti-clockwise, as seen in Fig. 9, under the action of springs S<SP>1</SP>, S2, and drives by a pawl and ratchet device v, w, a bevel wheel m which is suitably geared to the conveyer mechanism for the cartridge clips. Specifications 398,081 and 740,151 are referred to.

Title: Improvements in or relating to box wrapping systems
IPC: B31B15/00
Filed: 1944-08-21
Abstract: 598,469. Wrapping boxes. STOKES & SMITH CO. Aug. 21, 1944, No. 15937. Convention date, July 13, 1943. [Class 18] A box blank, stayed or unstayed, in erected position, is registered with and adhesively secured to a wrapper, label or other sheet material in a semi-automatic apparatus in which adhesive-coated wrappers &c. 27, Fig. 3, drawn, e.g., from a stack and passed through an adhesive-applying device, are fed on a suction conveyer 25 to a position in front of an operator's seat 15 where the conveyer comes gradually to rest for a predetermined period so that box blanks 42, fed by a second conveyer to the position shown on platform 44 may be moved by hand on to the wrapper, a corner 26a illuminated by a spotlight 52 being first positioned and the side of the blank being then brought against a stop 32. Conveyer 25 then gradually accelerates and conveys the assemblage forward. The stop 32 is carried on an adjustable cantilever arm 33. Wrappers are picked up from a stack S, Fig. 5, by a suction head 61 which passes them to rollers 64, 65 whence they pass through an adhesive-applying system and to the conveyer 25. The gradual acceleration and deceleration of the conveyer is effected by means of a drive embodying a link 108, cam follower 107 and pivot 109 which are so arranged that when the element 107 is engaging the driving element 92 of the conveyer it is, by reason of inclined surfaces on cam 101, travelling at an angular velocity different from that of driving hub 82 and pivot 109.

Title: Improvements in electric contact devices operated by rail deflection on the passage of a train
IPC: B61L1/04
Filed: 1936-06-08
Abstract: 458,657. Train -operated electric contact devices. FELTEN & GUILLEUME CARLSWERK AKT.-GES., M³lheim, Cologne, Germany. June 8, 1936, No. 15950. Convention date, June 8, 1935. [Class 105] Rail deflection causes a suction effect in a chamber thereby to close an electric contact at the moment of passage of a train. An intermediately spaced plate 4 is clamped between two plates 2, 3 to form upper and lower chambers 8, 9 communicating with the two limbs of a closed U -tube 16 having a mercury column adapted to effect a bridging of wire brush electrodes 19, 20 when a suction exists in the limb 18. Such suction arises when the plate 4 is moved downwardly by a plunger 10 operated through the intermediary of a double-wedge adjustment device 13, 14 from the rail. The pressure increase in the space below the plate 4 may be applied to the second limb 17 of the U-tube to aid the suction effect in the limb 18. A plurality of chambers may be connected in parallel. The plate 4 may only have a thin annular web near its periphery and in such case moves like a rigid piston.

Title: Improvements in and relating to the compensation of variations in the periodicity ofvibrating reeds or the like
IPC: H04L25/46
Filed: 1923-06-21
Abstract: 221,876. Higgitt, H. V., and Eastern Telegraph Co., Ltd. June 21, 1923. Constant-speed control systems. - Relates to apparatus for rendering constant the vibration periodicity of a vibrating reed &c. of the kind wherein a phonic motor rotates at a speed determined by the reed vibration periodicity and wherein a commutatory device and associated brushes are adapted to be rotated differentially from the shaft of the phonic motor, the arrangement being such that a current impulse is sent thrrough the reed-periodicity-varying device according as to whether the phase of the reed is ahead or behind the correct phase position with reference to a pendulum. The invention consists in means whereby an adjustment of phase is made simultaneously with actuation of the reedperiodicity-varying means. A make-and-break contact 2 connecting the battery 3 through the reed 1 to the phonic motor 4 ensures that the latter rotates at a speed determined by the periodicity of the reed. The shaft 5 is connected through suitable gearing to a shaft 6 carrying a brush 7 which contacts a commutator 8 on a rockable shaft 16. A pendulum 9 actuates contacts 10 sc that as momentary current is sent at fixed intervale through the brush 7, through the commutator 8 and through a device 14 which comprises any convenient arrangement, such as an electromagnetic motor device as described in Specification 221,844, [Class 35, Dynamo-electric generators &c.], to rock the shaft 16 and so move the permanent or electromagnet 15 to vary the reed periodicity. If the periodicity is normal, the brush 7 bridges the gap 17 between the two sections 18, 19 of the commutator, when current passes from the battery 11 and the device 14 is unaffected. If, however, the periodicity has changed, a current will pass down one or other of the sections 18, 19 and cause the magnet 15 to rock in ore direction or the other bv reason of the device 14 and thus restore the correct periodicity. The commutator 8 rocks with the magnet which restores the phase relationship as regards the brush 7 and pendulum 9, bringing the gap 17 beneath the brush 7 when the momentary current passes, and thus preventing " hunting ' or a continually-varying speed between two extreme positions. Instead of using the battery 11 directly a condenser may be used.

Title: An improved method for the manufacture of moulded articles from aqueous fibrous material
IPC: D21J3/00
Filed: 1949-06-17
Abstract: 695,354. Moulding fibrous pulp articles. MULLER, K. June 17, 1949, No. 16174/49. Class 87 (ii) The aqueous pulp is introduced through pipe c into cylinder f, at first under low pressure and then under high pressure. The water passes through the moulding sieve a into a casing i, which is secured to the sieve and rests on cylinder f. When the desired thickness of fibre b has been deposited on the inside of the sieve, a gas under pressure is introduced through pipe d (which is at this time in the raised broken-line position) and then pipe c is closed, whereupon the gaseous pressure discharges the pulp residue quickly through pipe e. Pipe d is then lowered and the sieve, casing g and moulded article are removed by lifting. The head of pipe d is so constructed that gas leaves it tangentially. Specification 691,853 is referred to.

Title: Method for making phosphonic acids or derivatives of phosphonic acids and products thereof
IPC: C07F9/40
Filed: 1947-06-19
Abstract: Phosphonic acid esters of the formula ROCH2PO(OR)2, wherein R is an alkyl group of not more than 4 carbon atoms are prepared by reacting a formal ROCH2OR with the trichloride or tribromide of phosphorus preferably in the presence of a Friedel and Craft catalyst, e.g. aluminium or zinc chloride.  The products which comprise an alkyl halide, an alkyl chloro (or bromo) methyl ether, a phosphonate ester and an undistillable residue, may be separated by distillation.  In an example butyl formal is reacted with phosphorus trichloride in the presence of aluminium chloride to give dibutyl butoxy methane phosphonate, which is insoluble in water and is used as a plasticizer. Dimethyl methoxy-methane phosphonate and diethyl ethoxy methane phosphonate are similarly prepared.  These compounds are water soluble.

Title: Circuit arrangement for processing data
IPC: G11B20/16
Filed: 1971-05-21
Abstract: 1344509 Clocking arrangements WESTERN ELECTRIC CO Inc 21 May 1971 [25 May 1970] 16228/71 Heading G4C A circuit for processing serial data read from a recording medium, e.g. a magnetic disc, having a timing track and a data track comprises means generating output pulses of a frequency n times that of the timing track pulses, a shift register connected to receive data read from the data track, a detector for detecting a significant data pattern in the shift register, gating means arranged to advance data through the shift register in synchronism with the output pulses, and a device responsive to the detection of the significant data pattern in the shift register and arranged to control the gating means to advance data through the shift register at a rate corresponding to the pulse repetition rate of the timing track.  As described clock 100 is phase locked to the timing track to generate pulses on lead 150 at a rate n times greater than the timing track. A signal on lead 110 indicates that a new sector of the memory tracks has come under the read heads and is operative to set flip-flop 111, and zero counter 120. Data is then advanced through shift register 125 at a rate corresponding to the frequency of the pulses or line 150 by means of AND gate 121 and conductor 123, the counter 120 being held in its zero state by a signal on line 119. At the beginning of each sector a preamble of a sequence of bit pairs "10" followed by a start pair "11" are recorded. As the shift pulse frequency is higher than the data rate the shift register is advanced n (e.g. eight) times for each data bit. At the point when the 1-0 transition in the preamble occurs a pair of adjacent shift register stages contain different bits. This is detected in stages 20, 21 by AND gate 129 which resets flip-flop 111 thus releasing counter 120. Because of the connection of AND 121 the shift pulse rate on line 123 is immediately reduced to that of the timing track (counter 120 serving as a divide by n circuit). The high frequency shift pulses divide each bit time into n phases and each bit is subsequently shifted into the shift register by a shift pulse one bit time after its predecessor, the first such shift pulse occurring one bit time after the detection of the preamble which is detected at the optimum time within a bit period by one of n shift pulses. Thus the time within each bit time at which the corresponding bit is read is optimized. Following detection of the preamble the 1, 1 start pattern is detected in stages 22, 23 by gate 130 which enables gate 114 causing flip-flop 112 to be set. AND 117 is thus enabled and each shift pulse is counted at 124 which is arranged to reset when a full word has been read into the shift register 125. When a full word has been read a signal on line 127 enables gates 128 which conduct to read out the word in register 125 at a time determined by counter 120 and gate 122, this time being shortly after the occurrence of the shift pulse for the last bit in the word.
