Abstract: 228,551. British Thomson-Houston Co., (Assignees of Stewart, G. E.). Jan. 28, 1924, [Convention date]. Systems depending on the use of two or more machines.-In systems in which an independently energized circuit 3, is to be supplied also from a source such as a generator 1, means are provided to allow supply from the generator but only when its voltage exceeds that of the circuit by a predetermined amount. With the circuitbreaker 2 open and switch 28 closed, the ungrounded side of the generator is connected to the mid-point 23 of the operating and controlling windings 11, 12 of a directional relay 7, such as is described in Specification 182.769, [Class 38 (v), Electrc switches &c.], the winding 12 is therefore across the terminals of the generator and the operating winding is between the ungrounded sides of the generator and the circuit 3. With these conditions the armature 8 will turn counterclockwise against the spring 21, if the generator voltage exceeds the circuit voltage by the predetermined amount, and close the contacts 19. 20 to complete the circuit of the closing coil 6 of the breaker 2. so that the generator can now feed the circuit. But closure of the breaker opens the contacts 22, so that the generator no longer feeds the coils of the relay 7. which are then in series and fed from the circuit 3 so that the armature is turned clockwise to open the contacts 19, 20. Closure of contacts 24 as the breaker closes, completes a circuit for the closing coil 6 in shunt to that through the contacts 19, 20, and containing, if desired, the contacts 25 of an overload cut-out 26.

Filed: 1933-01-26
Abstract: 413,755. Ink - ribbon mechanism. MERCEDES STERLING BOOK KEEPING & CALCULATING MACHINES, Ltd., 51, Gracechurch Street, and LEEDER, F. J., 11, Hargrave Mansions, Highgate, both in London. Jan. 26, 1933, No. 2551. [Class 100 (iv).] In a typewriter or like machine a tensioning- device is provided for controlling the ribbon between the winding and unwinding spools comprising means arranged to permit a predetermined length of ribbon to be wound on to the winding spool without unwinding from the other spool, while maintaining the ribbon taut. The device comprises a ratchet-wheel 13 rotatable with the unwinding spool 10, and a spring- controlled lever 15 carrying a roller 18 around which the ribbon 11 passes and a pawl 20 for holding the ratchet-wheel against rotation. The winding spool is driven intermittently, for example by pawl and ratchet mechanism operated by the movement of the typewriter &c. carriage. The spool 10 is loosely mounted on a spindle 12 to which the ratchet-wheel 13 is secured, and is engaged for rotation by a pin 14 on the spindle. The lever 15 is pivotally mounted at one end on a bracket 16, and carries the pawl 20, which is held in engagement with the wheel 13 by a spring 21. The lever 15 permits the spool 10 to rotate through a distance governed by the pitch of the teeth of the ratchet-wheel 13 when the tension in the ribbon 11 is sufficient to overcome the tension of the spring 21. The pawl 20 may be retained out of engagement with the ratchet-wheel 13 by a spring stop pin 27, which is loosely mounted on a stud 25 on the bracket 16 and adapted to pass through a hole 29 in the bracket to rest normally on the lever 15. When the lever 15 has been moved to the position shown in chain lines, the pin 26 is free to fall behind the lever and prevent return movement thereof. The spindle 12 can be manually rotated by means of an operating handle 24 attached to a plate 22 carrying a pin for engagement with a hole in the adjacent flange of the spool 10. Specification 6731/96, [Class 97], is referred to.

With the vehicle at rest, the bolt is held raised by a spring A actuating a lever F one end of which engages under a stud G on the bolt. When the vehicle is in motion a governor, not shown, driven from a vehicle axle, pulls a wire C attached to lever F, moving the lever so that the bolt is free to fall into engagement under gravity.

[Also in Group XXI] An inertia responsive device, particularly for use in a missile fuze or fire-extinguisher, comprises a housing 13, in which a member 11 is located in a non-operative position by a magnet 10, and a ball 12 disposed between a conical surface of the member 11 and the magnet 10. The member 11 carries an operating pin 11a When the device is subjected to a deceleration in the direction of the pin, the inertia of the ball 12 applies a force to move the member 11 away from the magnet 10, thereby to fire an explosive charge or to open or close electrical contacts. Alternatively, the magnet may have a conical surface and the member 11 may have a flat surface, or both may be conical surfaces. Specification 898,950 is referred to.

Title: Improvements in or relating to the production of ductile molybdenum
IPC: C22F1/18
Filed: 1952-02-01
Abstract: Ductile molybdenum or molybdenum alloy is obtained by heating the metal to a temperature between 800 DEG C. and the recrystallizing temperature, deforming the metal an amount equivalent to a reduction in area of 5-50 per cent. repeating the process of heating and deforming to effect a total deformation equivalent to a reduction in area of more than 60 per cent.-preferably 60-90 per cent.-and then annealing the metal at a temperature above the recrystallization temperature completely to recrystallize the metal.  The reheating may be performed in steps at decreasing temperatures between 900-1300 DEG C. and the recrystallization at temperatures between 1150 and 1650 DEG C.  The metal may be formed by powder metallurgy methods or by casting the liquid metal; in the latter case the as-cast metal may be repeatedly heated to 1450-1650 DEG C. followed by a 15-50 per cent. reduction in area to produce a grain size of 1-3 ASTM before being treated to produce ductile metal.  The finished metal should have a grain size not coarser than No. 6 ASTM.

Title: Improvements in or relating to pulse counting circuits
Inventor: DAVISON ALAN
IPC: H03K23/82
Filed: 1954-02-03
Abstract: 781,855. Electronic counting apparatus. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Jan. 27, 1955 [Feb. 3, 1954], No. 2763/55. Divided out of 781,854, [Group XXXIX]. Class 106 (1). [Also in Group XL (c)] A pulse-counting circuit comprises a number of gas-filled discharge tubes arranged to conduct successively in response to successive pulses applied to the circuit, the conduction of a counting tube extinguishing the previously conducting tube and priming a pulse-repeating circuit which responds to the next pulse to strike the counting tube next to the first-mentioned counting tube. The circuit is used to pulse and bias leads in the automatic telephone system described in Specification 781,854 [Group XXXIX]. Assuming that counting tube VC1 is conducting, the application of a pulse to lead 10 strikes pulse-repeating tube VR2, the resistance-capacitance networks of which make it self-extinguishing. The cathode pulse from VR2 strikes VC2 which extinguishes VC1. Successive pulses on lead 10 step on the chains VR1-VR5 and VC1-VC5, VC5 priming VR1 to form a closed ring. As the tubes VCI-VC5 conduct they bias leads B1-B5. As the tubes VR1-VR5 conduct they pulse leads P1-P5. The counter can be set to zero with VR1 primed by a pulse either on lead 11 which strikes VR5A and VC5 or on lead 12 to strike VC5A. The pulse-repeating tubes VR1-VR5 may be made self-extinguishing by an alternating anode voltage synchronized with the pulse input. The auxiliary tubes VR5A or VC5A may be added at any stage of the counter so that the count may be started from that stage. The + 50 V. bias at the trigger electrodes of the counter tubes may be controlled by an external circuit so that operation of the counter tubes can be started and stopped independently of the pulses on lead 10.
