Abstract: 610,106. Blasting-cartridges. CENTRE D'ETUDES M.B.A. (MECANIQUE, BALISTIQUE, ARMAMENT.). March 23, 1946, Nos. 9037 and 9038. Convention dates, Feb. 6, 1945, and Dec. 27, 1945. [Class 9 (i)] A blasting-cartridge based on the " hollowcharge " principle has a light cylindrical casing 1 closed at the rear by a plug 2 having its forward face 5 substantially conoidal, the centre part 4 being rounded to accommodate a priming charge 7, the forward face 8 of which is in contact with an explosive charge 10 so hollowed out that it has approximately uniform thickness in the direction of the axis of the casing. In addition a firing device is placed at the rear of the casing. Attached to the forward end of the casing 1 is an extension piece 11 having a bracket 12 for attaching the device to the object 13 to be drilled, the said extension 11 being of such a length that the distance of the charge 10 from the object 13 does not exceed 1.5 times the diameter of the charge 10. In use a combined detonator and fuze 15 is inserted in an axial hole in the plug 2 to contact the priming charge 7. On firing, the shape of the charges tends to focus the detonation wave along the axis of the casing 1 towards the object 13. To increase this focussing effect a funnelshaped member 18 may be inserted in the extension 11 with its nozzle end extending into a small hole 19 previously bored in the object 13. Modifications in the number and shape of the successive priming and explosive charges may be made. Recesses may also be provided in an intermediate priming charge to enhance the focussing effect. When a plurality of priming charges are used they are so chosen that the velocity of detonation of the several charges progressively decreases from rear to front of the device.

Title: Pulse generator
IPC: G06F7/68
Filed: 1965-03-04
Abstract: 1,035,603. Pulse generating circuits. RADIO CORPORATION OF AMERICA. March 4, 1965 [March 11, 1964], No. 9361/65. Heading H3P. In a circuit for generating a set of output pulses during a given time period, from a smaller number of input pulses supplied during the given time period, an oscillator is controlled by at least one of the input pulses, the output pulses being derived from gates controlled by the coincidence of input pulses and outputs from the oscillator. As shown in Fig. 8, the first input pulse TP1 (Fig. 9, not shown) is inverted at 40 and used to set a bi-stable circuit 44, the output of which enables a NOR gate 74 which propagates a step along a delay device 76. The output from device 76 is inverted at 78 and 80 and fed back to the NOR gate 74 so that, as long as the output from 44 is low, the circuit 74 ... 80 behaves as an oscillator generating antiphased square waves OSC#A, OSC#B, the duration of each half cycle corresponding to the required output pulse. The antiphased outputs are fed to alternate NOR gates 42, 48, 54, 60 which are in turn enabled by outputs from bi-stable circuits 46, 52, controlled by further input pulses TP2, TP3. At the end of input pulse TP3, a reset signal A is generated and fed to bi-stable circuit 44 so as to inhibit further operation. The circuit has thus generated four output pulses CP1 ... CP4 during a time period in which three input pulses TP1 ... TP3 have been received. In Figs. 10-12 (not shown) eight 0.75 Ás output pulses are provided during the application of seven 1À0 Ás input pulses, a pause of 1À0 Ás occurring between the fourth and fifth output pulse. The invention is applicable to the control of peripheral data processing equipment requiring a different clock frequency from the main equipment.

Abstract: 436,148. Automatic regulation. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. March 26, 1934, No. 9418. Convention date, March 25, 1933. [Class 38 (iv)] Compensation for wattless current flowing in a circuit is obtained by a capacitative device under the control of a power factor relay which is dependent on the phase angle between the supply voltage and the vector sum of the load current and a constant current which is proportional to that in the compensating device. The compensating condenser battery 2 is connected to the circuit 4 through a switch 3. A power factor relay 5 has its two potential windings energized from the supply voltage whilst the current winding is energized through a current transformer 6 and also from the phase of the circuit connected to earth through a condenser 7. This condenser 7 is suitably dimensioned so that the current through the relay corresponds with that taken by the battery 2. The relay always indicates the power factor when both the consumer 1 and the device 2 are connected to the circuit, and controls the moving contact 8 to complete a circuit for either the closing coil 9 or the opening coil 10 of the switch 3. Reference has been directed by the Comptroller to Specifications 362,134 and 370,890.

Abstract: 1,067,637. Welding by pressure. CATERPILLAR TRACTOR CO. March 3, 1966 [April 22, 1965], No. 9431/66. Heading B3R. [Also in Division B5] A bonding machine in which two parts WP-1, WP-2, Fig. 1, of unspecified material, are engaged in rubbing contact at a common interface while kinetic energy stored in rotating weights 76, Fig. 3, is discharged into the interface through frictional heating and plastic working developed at the interface as the rubbing contact slows the rotating weights 76 to stop at the conclusion of a bonding cycle, comprises a rotary spindle 41 to rotate the part WP-2, means 82 to attach a selected number of weights 76 to the spindle 41, and means 77 encircling the spindle 41 to store weights 76 not needed for making a particular bond. The non-rotating part WP-1 is clamped between jaws 19 to lie against an adjustable stop 24. The jaws 19 are actuated by an hydraulic cylinder 26, Figs. 1, 5 and 6 (the latter two not shown), having a piston rod (27) jointed to a pair of links (28) connected by bell cranks (29) each pivoted at (32). Downward movement of the rod (27) moves the jaws (19) into engagement with the part WP-1. The part WP-2 is provided with a twelve point drive tang to engage in a twelve point socket 71, Fig. 3, in a rotatable and axially movable chuck 21 secured to rotate with the spindle 41 continuously driven by a motor 36, Fig. 1, through a gear train 37 and a spline connection 53, Fig. 3. Jaws 56 clamp the part WP-2 in the chuck 21 and are actuated by a cylinder (58), Fig. 7 (not shown), in the spindle (41) through a linkage (59). A ram piston 44, Fig. 3, is mounted by bearings 42, 43 on the spindle 41 and is mounted for vertical movement only in a fixed cylinder 46. A pressure chamber 48, 49 is formed on each side of a head 47 of the ram 44 and fluid pressure is supplied via conduits 51 by valves (not shown). A rotary seal 66 prevents loss of fluid between the spindle 41 and the ram 44. A cup-shaped container 77 is secured to the non-rotary ram 44 and is formed on its bottom wall with a stepped configuration 78. Each weight 76 has a corresponding stepped configuration so as to interlock with the wall and with one another to keep the stored weights out of contact with the spindle 41. Cap screws 82 are inserted through openings 81 in a flange 79 to pick up the desired number of weights 76 required for a particular bonding operation. In use, the parts WP-1, WP-2 are positioned between the jaws 19, 56, respectively, with the ram 44 and the spindle 41 in the lowermost position. Fluid is supplied to the chamber 49 to move the ram 44 upwards and the motor 36 is energized to bring the spindle 41 and attached weights 76 to the desired speed before contact is made between the parts WP-1, WP-2. A sensing mechanism de-energizes the motor 36 so that the spindle runs freely. The parts are brought into contact under pressure and the frictional contact therebetween slows the spindle 41 to a stop at the conclusion of the bonding operation.
