Patent GB-182228-A (GB)
Title: Improvements in and relating to reversing gear for internal combustion engines
IPC: F01L13/00
Filed: 1921-04-06
Abstract: 182,228. Marks, E. C. R., (Marswerke Akt.-Ges.). April 6, 1921. Reversing.-In an engine in which reversing is effected by means of an additional fuel-pump, working out of phase with the normal fuel-pump, the stroke of the additional pump actuates means for stopping the additional pump and re-starting the normal pump. In the form shown, the pumps I, II are actuated by rollers 3, 4 on a common rocker g. Between the roller 3 and the picton v of the normal pump I are interposed a plate 19 and a rod b slidable in a guide 20 and in a hollow toothed wheel 8 with an externally threaded hub c. Between the roller 4 and the piston w of the pump II is a piston a carrying a striker n for engagement with an inertia tappet m pivoted at o on the piston w. Reversal is effected by a spindle u adjusted by means of a handle Y and bevel-gearing 11, 13. The spindle u carries a slidable coupling-member f held by a spring 22 in engagement with the hub of a pinion 7 on the upper end of a spindle h, which is held in the normal position by a torsion spring t. A cam d on the lower end of the spindle h normally engages beneath the piston a and holds it clear of the roller 4. When the shaft u is turned into the reversing position, the pinion 7 rotates the pinion 8, the threaded hub of which causes the pinion to lift the plate 19 out of the range of the rod b so that the pump I ceases to act. The cam d is withdrawn from beneath the piston a, which is brought by a spring 14 into contact with the actuating roller 4. A cam p on the pinion 7 releases an arm 18 on the tappet m, which is moved by a spring 15 into the path of the striker n and is actuated thereby when the speed has fallen sufficiently. The resulting stroke of the piston w reverses the engine and also lifts the coupling member f by means of a disc i, allowing the spindle h and associated parts to be returned to the normal position by the spring t.

Title: Injection moulding machines
IPC: B29C45/70
Filed: 1961-03-21
Abstract: 960,638. Injection moulding machines. TOS RAKOVNIK NARODNI PODNIK. March 21, 1961 [March 24, 1960], No. 10193/61. Heading B5A. In an injection moulding machine, hydraulic cylinders 3, 7 for the operation of the injection piston 4 and for closing the die parts 26, 27 respectively, are mounted on the same side of the die, the die part 26 being fixed to a plate 10 which is directly connected to piston rods 12 actuated by hydraulic cylinders 7. When fluid under pressure is supplied to spaces 20 in the cylinders 7 the die part 26 is closed against the die part 27 causing it to move against springs 11 until stopped by adjustable inserts 21. This brings the die part 27 into engagement with the nozzle 6 of the injection cylinder, and the piston 4 is then actuated to fill the die. To open the die fluid under pressure is supplied through bores in plungers 25, which are fixed inside the cylinders 7, to cylindrical spaces 24 formed inside the piston rods 12.

Title: Improvements in telegraph printer systems
IPC: H04L15/12
Filed: 1937-04-09
Abstract: 493,467. Type - printing telegraphy. FINCH, W. G. H. April 9, 1937, No. 10217. Convention date, April 10, 1936. [Class 40 (iii)] A telegraph transmitter suitable for use with the receiver described in Specification 437,303 or other code telegraphy system generates, on the depression of any key, a predetermined number of short impulses some of which, according to the key depressed, are modified to become long impulses. A number of permutation bars 12, are arranged beneath the key bars 10 so that on depression of a key they are either held or capable of lateral movement when urged successively by rotating cams 14 on a shaft 60 driven through a friction clutch 63, 64 by a constantly rotating motor 69. The permutation bars, when so moved, close contacts 16, 17 by means of a common bar 41. The construction of the central permutation bar is such that it is not held by any of the key bars and its associated cam has twelve equally spaced projections so shaped as to send eleven dots and one dash per revolution. The remaining cams each have one projection only corresponding to a dash and are arranged helically so that each is in a position corresponding to one of the projections on the central cam. Thus any bar which is not held by a key, when moved, converts the corresponding dot of the central bar into a dash. A detent, Fig. 4 (not shown), operated directly by the depression of any key releases the cam-shaft, and allows it to make one revolution and a mechanism operated through a lever 88 by a cam 62 holds the keyboard locked until the revolution of the cam-shaft is almost completed.

Title: Magnetic device
IPC: G11C19/08
Filed: 1972-03-06
Abstract: 1367474 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 6 March 1972 [12 April 1971] 10270/72 Heading H3B Bubble domains are propagated in a magnetic sheet 10, Fig. 2, by current pulses in straight conductors 12-1 to 12-N. The magnetic field associated with a conductor such as 12-1 opposes the domain stabilizing field Hz on one side of the conductor and enhances it on the other; this effective variation of bias field causes a domain to move, and if alternate conductors are pulsed 180 degrees out of phase the domain will move along the sheet, following the region of least bias field. The stable domain positions are to one side or the other of the conductors as shown by numbers 1-8 on Fig. 2. Because the conductors pass to and fro across the sheet bipolar propagation pulses are used, the motion from positions 1-8 being as shown in Fig. 3; propagation in the opposite direction occurs if the currents I 1  or I 2  are reversed. In Fig. 2, a domain generator 16 has four current hoops 16L, 16S, 16R and 18. Initially 16S is pulsed to create a domain, then 16L and 16R are pulsed with loop 18 and the domain splits into two portions which move under loops 16L and 16R. The latter portion is offset by permalloy dots 20 and can be propagated by currents I 1  and I 2 . The portion under loop 16L may be returned to loop 16S and split to form another domain for propagation, the process being repeated as required. At the other end of the sheet a bubble busting loop 32 is provided. Readout is by a magnetosensitive resistor 26 connected to constant current source 28 and voltmeter 30 as described in Specifications 1,334,603 and 1,358,546. Parallel propagation paths may be used along the sheet with an appropriate number of generators, detectors and busters. The one set of propagation conductors remain sufficient however, though permalloy keeper regions are applied to them to prevent the domains drifting sideways, Figs. 4 and 5 (not shown). The keepers also raise propagation efficiency. The conductors may be arranged to give a closed recirculating path. A looped conductor may be provided adjacent the input of each path to collapse a domain when it is desired to write a binary 0.

Title: An Automatic Time Switch Mechanism
Inventor: TROXLER LEO
IPC: G04C23/06
Filed: 1967-03-06
Abstract: 1,185,705. Retarding action of switches. L. TROXLER. 6 March, 1967 [5 March, 1966], No. 10404/67. Heading H1N. Operation of a latching push button closes a microswitch and engages a clutch to a time drive which after a preset interval releases the latch to open the switch and disengage the clutch to allow the mechanism to return in readiness for subsequent operation without resetting. A frictionally restrained setting knob (8, Figs. 1 and 3, not shown) is rotatable between 180-degree limits to predetermine a time interval and directly moves a coaxial limiting member 22 carrying an integral abutment 25. A member 24 having an actuating nose 27 and an internal abutment 24a is carried on a loose shaft 16b and is coupled to member 22 by a spring 26 such that abutment 24a is normally held against abutment 25. Depression of the end of a lever (9, Figs. 1 to 4, not shown) urges a pin 6 axially inwards against a lever (5) which actuates a microswitch (3) and clutches shaft 16b to a drive from a geared synchronous motor (1, Fig. 3, not shown). Pin 6 is latched in this position by a shoulder 21 thereon engaging behind a spring-urged lever 19, until the drive to shaft 16b has rotated nose 27 to engage the extension 28 and thereby disengage lever 19 from shoulder 21. The pin 6 is thus released, the microswitch opens and the clutch to shaft 16b is disengaged, whereupon spring 26 returns abutment 24a to its starting position (preset by abutment 25) in readiness for another operation without resetting abutment 25 unless it is desired to change the time delay interval.

Abstract: 934,113. Loading silos on to vehicles. PORTASILO Ltd. March 22, 1962 [March 22, 1961], No. 10502/61. Class 78 (4).  A strut 10 pivoted at 11 to a concrete silo 1 or similar container can bear on the load surface 8 of a vehicle to control tilting of the silo on to and from the vehicle. In the form illustrated the strut 10 is a U-shaped member carrying rollers 12, and its movement is controlled by a cable 14 connecting it to the legs 4 of the silo and operated by a winch 13 mounted either on the strut or on the silo. A removable brace can be connected from the legs 4 of the silo to the lower end of the strut 10 to locate it while the silo is tipped to effect initial engagement with the vehicle. This tipping may be effected by connecting a chain 17 to a line passed round a pulley (not shown) at the forward end of the load surface 8 to the winch 13. The chain 17 is subsequently connected as illustrated. After a cross brace 6 on the silo has engaged on the load surface 8 the silo pivots about the cross brace 6, still under the control of the winch 13. The winch 13 is similarly used to raise the silo from the vehicle. Jacks may be provided under the feet 5 of the silo to effect the initial tipping. The winch 13 may be replaced by a chain-puller. The keel 9 of the silo may be continued to reach the ground, and may form a skid for engagement with the load surface 8. Further lashings may be provided for preventing undesired movement of the silo. The loading and unloading operations may be assisted by movement forwards or backwards of the vehicle.

Abstract: 610,290. Feeding sheets to machines. CRABTREE & SONS, Ltd., R. W., and BURLS, J. A. E. April 6, 1946, No. 10672. [Class 100(i)] For feeding folded signatures to sewing- machines the folded edges of the signatures are opened out so as to permit pushing devices 9 with pushing fingers 7, 8 to engage between the centre pages of the signature. This is effected as shown in Fig. 2 by causing grippers 2 to engage the folded edge of a signature near the edges thereof, and striking devices 6 with inclined surfaces 4, 5 are moved to contact the folded edges and by movement away from the fold to cause the edges to bulge which permits the pushing fingers 7, 8 to move between the centre pages and when the motion of the fingers is reversed and the grippers 1, 2 opened, the pushers 7, 8 carry the signature to a position in which it can be engaged by a V-shaped stitching head 34, Fig. 5, which is oscillated on a guide 36 by an oscillating lever 37. As shown in Fig. 5 the signatures are fed singly from the bottom of a hopper 12 by means of oscillating,suction devices 16, which withdraw the bottom sheet past a flexible support 15 through an aperture in the bottom 13 of the hopper, and deposit the fold of the signature on a fixed gripper 2 against which moves a gripper 1 carried by a member 41 mounted yieldingly in an oscillating carrier 21. The member 41 assists separation of the signatures as it passes between the separated one and the pile. The gripping action is followed by advance of the striking devices 6 which are moved against the action of springs 33 by advance of the pushing rod 9 which finally is moved so that the pushers 7, 8 engage the opened fold of the separated signature. The rod 9 is reciprocated by a slitted lever 30 which engages a pin 29 on the rod, and the lever 30 also actuates link work which effects oscillation of the lever 17 carrying the suckers 16. The rod 9 also by means of a block 46 actuates a pivoted member 47 connected to a tappet shaft 25 which lowers the gripper member 1.
