Abstract: 617,852. Cable-cutting guns. TEMPLE VELOCITY EQUIPMENT, Inc. Nov. 6, 1946, No. 32949. Convention date, Feb. 11, 1944. [Classes 9 (i) and 119] A hand-operated explosively-actuated tool for cutting cables under water and for like operations has, at the end of a handle, a frame with a cable-receiving recess communicating through a barrel in the frame with a chamber block having a plurality of chambers which can be selectively brought into alignment with the cable recess by sliding the block transversely through the frame. Further, each chamber is adapted to receive a projectile member propelled to cut a cable held in the recess by firing a cartridge in an opening behind the chamber. Furthermore, by a continuation of the sliding movement, the chamber or chambers are made accessible for loading. A metal frame 1 with a recess 2 has a transverse slot 3 accommodating a chamber block 4 having elongated chambers 6 and 7, the chamber 6 being in alignment with a barrel 8 communicating with the recess 2 and in alignment with a passage 12 in a cutting block 10 in the front of the frame 1. Each chamber 6, 7 contains a projectile held at its forward end by a shear pin projecting into a counterbore in the chamber block. Behind each projectile is an explosive cartridge 21, the cartridge in chamber 6 being aligned with a firing pin 22 slidable in a breech member 24 and held away from the chamber block by a spring 26. A spring 27 is compressed by a pull on a flexible line 38 attached to an actuating element 36 engaging with the free end of a cocking lever 32. The element 36 after moving the lever a certain distance slides over it whereupon the spring 27 is released and kicks the firing pin forward to detonate the cartridge 21. When the explosive pressure becomes sufficient to shear the pin, the projectile is driven forward through any obstruction in the recess 2. The lever 32 is recocked by sliding the actuating element 36 forward by hand and chamber 7 is brought into register with the barrel 8 by sliding the chamber block in the frame. A spring-pressed plug 48 in a transverse opening in the frame 1 can be brought into register with any one of sockets 45, 46 and 47 in the chamber block according as chamber 7 is being loaded, chamber 6 is in alignment with the barrel 8 or.chamber 7 is in alignment with the barrel. When chamber 7 is in alignment with the barrel, chamber 6 is exposed for reloading. A stop screw 52 on the opposite side of the frame is provided to limit the sliding movement of the chamber block. The firing pin may be locked by a safety key extending through the breech member and the firing pin.

Abstract: 307,448. Hadfield, G. H., and Sand & Shingle, Ltd. Dec. 8, 1927. Building-materials, special.-Coloured sand and the like is prepared by-mixing colouring matter, sand or other finely divided base, and a proportion of cement sufficient to bind the colouring matter to the particles of the base but insufficient to produce a stable solid body as a finished product. The mixture is allowed to set and is then broken down by slight-pressure into particles of approximately the same size as those of the original base. In making a tennis court, the cement mixture may be laid on a suitable foundation, allowed to set and then broken down by rolling. To form a composition specially suitable for hard tennis courts, the coloured sand is incorporated with from 3 to 6 per cent of an oil, grease, varnish, or other oily binder. For colouring matter, various earth or mineral colours, aniline dyes, and other organic colours may be used, provided they are fast to the action of cement. Examples of colouring matter giving a green colour are glauconite, copper sulphate mixed with the gauging water, and a mixture of Lake green B and Monolite yellow G_

Abstract: 1,198,803. Making electrical contact rivets; forging; extruding. JOHNSON MATTHEY & CO. Ltd. 12 July, 1967 [26 July, 1966], No. 33598/66. Headings B3A, B3H and B3P. A trimetallic rivet-type electrical contact is made by deforming a bimetallic billet to form an extruded shank and a forged head, the original cross-sectional area of the billet being greater than the cross-sectional area of the shank but less than the maximum cross-sectional area of the head. In one embodiment, Figs. 9 and 11, a billet 18 consisting of a copper cylinder 19 bonded to a silver cylinder 20, is partly extruded to form the shank, after which the blank is transferred to a die block 24 and the head 28 cold formed by a tool 27. In another embodiment, an extrusion die 36, Fig. 12, is moved downwards to extrude a shank from the billet 30 located on a plunger 35 in a spring-loaded die 32. After the billet has been expelled from the die 32 by the plunger 35, the extrusion die 36 carrying the partly formed contact is moved laterally and then downwards on to a cold forging die (41) (Fig. 15, not shown) to deform the unextruded part of the billet into the head. The contact head is removed from the forging die (41) by a plunger (43) and the contact expelled from the extrusion die 36 by a plunger 37. The contact head may be other than cylindrical such as square, frusto-conical or part spherical, or may be elliptical shaped, formed from a billet of rectangular section.

Title: Improvements relating to automatic slack adjusting devices for braking apparatus on railway and other vehicles
IPC: B61H15/00
Filed: 1935-12-04
Abstract: 466,792. Compensating for wear in brake mechanism. BRACKENBURY, A. G., and WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Dec. 4, 1935, No. 33618. [Class 103 (i)] In a slack-adjusting device of the kind comprising relatively movable parts having co-operating screw threads and mechanism for effecting the relative displacement of the two parts comprising a ratchet wheel on one of the parts engaged by a fixed pawl and a driving pawl, the parts and the mechanism are enclosed in a tubular casing. The internally screwed non-rotatable member 2, connected to the brake rigging 3<1> is slidable in a casing 1 in which the externally screwed member 4 is rotatable in bushes 5, 6. A housing 6 forming an extension of the casing encloses a ratchet wheel 8 secured to the reduced end 7 of the member 4 and engaged by a locking pawl 9 and a driving pawl 10 mounted in a member 11 rotatably mounted on the end 7. The casing is supported from the vehicle underframe by a link 17, the point 19 being normally slightly to the left of the point 18 so that the casing which moves to the left when the brakes are applied returns by gravity. The brake operating shaft 14 is connected by a lever 15 and bracket 16 to the casing 1. The lever 15 has an arm 13 connected by link 12 to the pawl casing 11 through a part 20 which is rotatable on the casing 11 so that the link 12 may extend upwardly if required instead of downwardly as shown. If in applying the brakes, by counter-clockwise rotation of the shaft 14, the slack in the rigging exceeds a predetermined amount, the pawl 10 slips a tooth of the ratchet wheel which is then turned on the release movement, thus turning the member 4 and causing the member 2 to slide farther into the casing 1 to shorten the effective length of the members. The pawls 9, 10 can be disengaged by levers 28, 29 from the ratchet wheel to permit re-setting of the device by turning the member 4 the end 7 of which extends from the casing for this purpose. In a modification, the link 12 is connected, instead of to the arm 13, to one arm of a bell-crank, pivoted on a bracket secured to the casing 1, the other arm being anchored by a link to the vehicle underframe. Indicators, applications of. A signal arm 21 pivoted at 22 to the casing 1 is connected by a link 23 to the member 2 at 24 whereby the arm 21 assumes a vertical position when the device requires re-setting.

Title: Masking arrangement for digital computer apparatus
Inventor: OBLONSKY JAN
IPC: G06F9/308
Filed: 1965-08-06
Abstract: 1,072,764. Electric digital computer; data storage device. VYZKUMNY USTAV MATEMATICKYCH STROJU. Aug. 6, 1965, No. 33794/65. Headings G4A and G4C. A digital computer has a memory, an arithmetic section 8 and a data modification section which includes a shift register 12, a masking register 3 having a controllable masking format and a control 2 for determining the format, the register acting to inhibit predetermined portions of a word stored in the register 12 and permitting only such portions of the word to be read out as determined by the content of the masking register. As described a 12-stage shift register is used having an output line 104 connected to stage 1 and an output line 103 connected to stage 7. Each output line plus a line from a null or zero generator 51 passes via AND gates 54, 53, 52 respectively to an OR gate, from where the combined signals pass to the arithmetic unit 8. A line from the arithmetic unit and a line from the masking register 3 are connected to the control 2 which in turn enables output gates 52, 53, 54 and input gates 62, 63. The control can choose one of three formats of the masking register. Predetermined numbers in a 12-stage word in the masking register, acting according to the determined format, inform the control which of the AND gates to open or close, and whether to shift the register 12. For instance in one format a " 9 " in the masking register causes a shift left, closing of gates 53, 54, 62, 63 and opening of gate 52, thus losing the digit in stage 1 of the shift register and replacing it with zero. A " 7 " does not shift the register but enables or inhibits the same gates. A " 0 " enables gate 54, inhibits the others and shifts left thus passing the 1st stage digit in register 1. A " 3 " enables gate 53 to pass the 7th stage digit. In one example a number 780326273105 is entered in register 1 and a mask 999999000999 in the above mentioned format is used to produce number 000000273000 to be entered into the arithmetic section. 346789876543 operated on by 707070707070 produces 080706050403.

Abstract: 1,260,239. Recording and playback. RCA CORPORATION. 4 July 1969 [11 July, 1968], No. 33886/69. Heading G5R. A magnetic storage drum assembly comprises an arrangement for pre-stressing the peripheral wall of the hollow magnetic drum of the assembly in the direction along the axis about which it is rotatable on bearings able to withstand axial thrust. The arrangement incorporates a flexible end wall for the drum which is resiliently deformable by an adjuster in order to -establish and maintain the prestress, the end wall being connected towards its centre to one race of one of the bearings, the other race of this bearing being connected to a drum support. Previous drums have normally been fixed to a bearing at one end and allowed to slide relative to a bearing at the other end. By the present arrangement, the maximum possible displacement of the-drum relative to recording playbackheads in the drum housing, due to thermal expansion etc., is halved relative to that which might occur in the previous drum assemblies. To effect the axial prestressing, the drum is provided with flexible dished end walls 24, 26 of the same material and thickness as the drum. These have threaded bosses which receive screws 34, 34a to adjust the position of the end walls relative to bearing support structures 30. The support structures are fixed to outer bearing races 31. The drum is driven by an induction motor at each end, the rotor coils 44 being mounted on the structures 30 while the stator coils 42 are mounted in the drum housing. Hollow bearing shafts 36, 36a are provided, to which the inner bearing races 32 are attached and through which the screws 34 may be adjusted. The recording playback heads 19a ... 19n are supported in the drum housing 18, their associated circuitry being disposed in apertures 20. The whole assembly is contained within a screening cover 12. The circumferential drum wall is thin relative to the housing thickness and is closely spaced therefrom so as to minimize possible temperature differentials between the two.
