Title: Machine for manufacturing vibrated, moulded, cored bodies
IPC: B28B1/093
Filed: 1944-11-10
Abstract: 594,963. Moulds for concrete &c. blocks. LILJENBERG, O. B., Nov. 10, 1944, No. 22212. [Class 87 (ii)] When a hand lever 15 is operated to release a latch 14, weights 13 (or springs) pivot levers 12 about fulcra A and raise both the mould 4 and the discharge table 29 from the position shown in Fig. 1 to the position shown in Fig. 2, the moulded article being thus stripped off stationary vibrated cores 2a. A transverse shaft 22 on the mould is then engaged in the forked upper ends of uprights 21, a handle 25 on the mould is grasped, and the mould, with a cover-plate 24 attached thereto by a strap 25a, is swung over through 180 degrees and lies bottom uppermost on the ends of standards 26. The cover-plate 24 is then released by loosening strap 25a, and a discharge plate (not shown) is depressed to push the article on its cover-plate out of the mould on to spring plates 31 on the table 29, the perforated bottom plate 4a being retained in the mould by means not shown. The weight of the article and cover-plate on the table causes it to descend to the position shown in Fig. 1, whereupon the levers 12 are locked by latch 14 and the coverplate and article removed. During filling and vibration the mould is supported by a frame 5, and when the mould is lifted (by rods 9 co-acting with trunnions 7 on the mould) weights or springs (not shown) raise the frame to the Fig. 2 position. A treadle (not shown) is used to exert pressure on levers 12 to loosen the article from the mould.

Abstract: 379,830. Targets. WIEDECK, M., 27, Koppenstrasse, Berlin. Aug. 7, 1931, No. 22400. Convention date, Dec. 19, 1930. [Class 20 (i).] A pivoted target which drops on impact by a bullet has means operated from the firing point to raise it, the parts being so disposed that the impact of the bullet is not transferred to the raising mechanism and means being provided to operate by the raising means to trip the target when upright. The target 8 is clamped to a carrier 5 pivoted at 4 to brackets 3, the carrier being retained with its lower end contacting with an adjustable stop 13 so as to expose the target in upright position by means of a gravity catch lever 16 pivoted at 15, a shoulder 18 on the lever engaging a recess 24 in an eccentric segment plate 21 fixed to the carrier. The catch lever is also provided with an inclined slot 19 and the end of a rod 27 is provided with a free pawl 35 and engages an eccentric slct 22 in the segment plate.. An operating lever 29 is pivoted at 30 and is pinned to the end of the rod 27 at 28 by a spring connection which allows vertical movement of the rod with respect to the lever. Stops 31, 32 are provided to limit the movement of the operating lever. When the target is struck by a bullet the gravity catch 16 is shaken loose and drops, and the target falls forward to the position shown in Fig. 6, the pin 36 sliding in the slot 22 to the front end. To restore the target, the lever 29 is actuated so that the rod 27 is pushed forward, thus raising the target, a stop 38 on the rod engaging the end 17 of the gravity catch and pushing the catch into position to retain the carrier in upright position, Fig. 8. On the return of the rod it may lift to pass over the end 17 of the gravity catch, the spring 37 allowing this, and the position shown in Fig. 2 is attained. If now the operating lever be again actuated, the pawl 35 will engage the inclined slot 19 in the gravity catch and depress it and so trip the carrier.

Title: Improvements in electric protective and/or fault locating systems for polyphase alternating current power-transmission networks
IPC: H02H3/40
Filed: 1951-10-01
Abstract: 743,323. Protective cut-out systems. GIBSON, A. B'., and CENTRAL ELECTRICITY AUTHORITY, [formerly BRITISH ELECTRICITY AUTHORITY]. Jan. 1, 1953 [Oct. 1, 1951], No. 22868/51. Class 38(5) A polyphase distance protective system has current transformers 1a, 2a, 3a supplying a static network indicated at 4 which provides single-phase quantities I 1 , I 2  and KI o , the quantities I 1 , I 2  and I 0  being posi- .tive, negative and zero phase sequence current components respectively and K being the ratio of the zero sequence impedance to the positive sequence impedance. Voltage transformers 1b, 2b, 3b supply a further static network indicated at 5 which provides single-phase quantities V 1 , V 2  and V 0 , these quantities being positive, negative and zero phase sequence voltage .components respectively. These current and voltage components are supplied through transformers 12 to rectifiers 6 ... 11, the rectifiers 6, 7, 8 being connected so as to energize the direct coil 13a of an impedance relay 13 with a direct current proportional to 1, + I 2  + KI 0  and the rectifiers 9, 10, 11 being connected so as to energize the voltage coil 13b with a direct current proportional to V 1  - V 2  - V 0 . The arrangement so far described is stated to give equal distance response under singlephase-to-earth, phase-to-phase and threephase fault conditions. To provide equal response under two-phase-to-earth fault conditions, a double-earth fault selector relay 18 has one winding energized by the rectified positive phase sequence current I, and a second winding energized by the retified negative phase sequence current I 2 . When I, exceeds I 2 , the relay 18 opens contacts 19, 20 so that the relay 13 responds to the functions (I, + I 2 ) and (V 1 - V 2 ) only. A directional relay 16 energized by the alternating components V 1'  I, controls contacts 17 which short circuit the relay coil 13a except when the direction of flow of positive sequence power in the protected feeder 1, 2, 3 is away from the station bus-bars (not shown). In the example shown, the relay 13 is a first zone relay and closes contacts (not shown) to trip a circuit-breaker immediately on the occurrence of a fault within its zone. A further, second zone, relay 14 has contacts (not shown) which control a time-delay relay (Fig. 2, not shown). Other impedance relays in conjunction with time-delay relays may cover further zones. Alternatively,. a single impedance relay may be used to cover all the zones, the relay having its impedance setting varied by means of a time-delay mechanism. The location of a fault may be determined by observation of the number of zonal impedance relays which operate, or where the single relay is used by observation of the setting at which the relay operates.
