Title: Improvements in or relating to superconductive circuits
IPC: G11C11/44
Filed: 1962-12-04
Abstract: 1,006,684. Superconductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 4, 1962 [Dec. 7, 1961], No. 45738/62. Heading H3B. A superconducting path L comprising a series of cryotron gates 2, 4, 6 &c. controlled by conductors 28, 30, 32 &c. is combined with equipment for timing the fall of current in path L to a predetermined level. Constant current from a source IS is initially directed wholly to path L by a pulse applied to the control winding 14 of cryotron gate 12. When one or more of the gate conductors 2, 4, 6 &c. are driven resistive, the current is diverted to a parallel path R and the time taken by the diversion depends upon the number of resistive gates. The path R feeds in parallel a number of flipflop indicators 22, 24, 26 &c. through AND gates 16, 18, 20 &c. respectively. The AND gates are marked by timing pulses t1, t2, t3 &c. The first AND gate to operate is followed by a flip-flop to indicate when the critical operating current of the AND gates was reached. The gates 2, 4, 6 &c. may each have two or more control conductors to enable the signals on different sets of control conductors to be compared.

Abstract: 1440649 Shovelling machines MITSUI SHIP BUILDING & ENG CO Ltd 5 Oct 1973 [5 Oct 1972] 46611/73 Heading E1F A shovelling unit for mounting on a frame, e.g. a vehicle chassis, comprises a link mechanism mountable on the frame, a bucket pivoted at its base to the outer end of the mechanism, stop means adjacent the upper portion of the link mechanism for regulating backward tilting of the bucket, a ram pivotally connected between the link mechanism and the frame, and flexible means arranged to interconnect the upper portion of the bucket and the frame. The unit is so contrived that on the bucket being moved to an upper, predetermined position by operation of the ram, the bucket automatically tilts due to the weight of the bucket either rearwards to a dump position or forwards to a loading position. The flexible means is under tension when the bucket is being raised to said upper position and is relieved from tension and flexes as the bucket on reaching said positions tilts to the dump position. Preferably the link mechanism comprises links 13, 20, 21 although links 20, 21 may be omitted and the ram 22 is caused to act directly 'between links 13 and the frame F. The flexible means may comprise either links 15, 16 with link 16 co-operating with a stop 23 on the chassis or a chain or a wire.

Abstract: 1,164,628. Oil filter. BLACKSTONE & CO. Ltd. 4 Nov., 1966, No. 49501/66. Heading BID. [Also in Division F2] A filter for lubricating oil in a marine diesel engine comprises two filter elements (43, 44) in separate bowls clamped to a common head, the head comprising inlet and outlet connections 72, 73 and spool valves 67, 68, which are moved in unison by an external handle (21) to direct oil through one or other of the elements and may be arranged so that oil flows through both elements in parallel during changeover. Alternatively, a pressure operated by-pass valve (94-100), (Fig. 7 not shown) opens during changeover to maintain the flow. During running-in of the engine, flow may be through pleated paper element (43), after which the flow is transferred to coarser gauze element (44), while the element (43) is replaced by a further gauze element for reserve. The spool valves 67, 68 carry teeth engaging a cog rotated by the handle (21) which has a locking means (30-34) for holding it in either of two extreme positions in which the handle obscures characters indicating which filter element is in use (Figs. 1-3, not shown). Connections 72, 73 open into respective chambers 80, 78 communicating by passages 71, 70 with chambers 81, 79, and as shown flow is through bores 88, 89 to and from the left hand element which is enclosed in a removable bowl (41) in series between ports 35, 37. Connections 72, 73 could equally open into chambers 81, 79 by apertures shown closed by plugs 75, 74, or all four positions could be used, with the filter connected between two engines or circuits in one engine. The various lands 87, 91, 83 on the spool valves carry sealing rings and vary stepwise in diameter along the valve to facilitate manufacture. A three-way valve (110) is used to direct filtered oil from one element to fill the bowl of the other after replacement, valves (115) being unscrewed to permit the trapped air to vent (Figs. 4, 6, not shown). The filter also comprises a differential pressure alarm switch (117) and plugs (118), 77 providing access for cleaning the valve interiors.
