Abstract: 1525009 Memory system INTERNATIONAL BUSINESS MACHINES CORP 14 Nov 1975 [20 Dec 1974 (2)] 46968/75 Heading G4A A large scale integrated circuit device, e.g. a memory, includes a main circuit unit (the memory array) normally accessed from terminals on the device through auxiliary circuitry (associated logic circuits, decoders, &c.) and a by-pass mechanism operative so that the main circuit unit can be assessed directly from terminals on the device for test purposes. Two embodiments are described. In the first the integrated circuit includes a main memory array 15 incorporating switchable gates 19, 20, 21 responsive to control signals ATL, ITL, OTL fed in via device inputs selectively to connect address and data inputs to the array and data outputs from the array directly to terminals on the device and to associated logic units, decoders, &c. 12, 13, 14 which receive their inputs from terminals on the device. In normal operation the logic circuits are used to transfer inputs to the memory array in accordance with the design of the device. However for test purposes the array may be tested in isolation by feeding it data direct. Subsequently the various logic circuits may be tested by the appropriate choice of direct and normal input/output routes. In the second embodiment the array includes address, data input, and data output registers which may be clocked to receive data via the associated logic circuits. The data and address registers are formed as master/slave shift registers and may be clocked to receive data serially direct from and send data serially direct to external inputs and outputs of the device. The data output register may be connected to feed data directly to a comparator where it is compared with the expected output and to a shift register which is arranged to receive complementary output signals. The arrangement allows operation of the address and data input registers to be checked individually and the memory array itself to be checked by comparing the output with that exepcted.

Abstract: 1291502 Valves TEVES-THOMPSON GmbH 9 Oct 1970 [6 Nov 1969] 48130/70 Heading F2V  A poppet valve is rotated as it approaches its seat by a device disposed around the valve axis and having a number of rolling or sliding elements 2 (Figs. 2a, 2c) displaceable along tapered grooves 4 in a member 3. When the valve is open, its loading spring acts through a cage 6 to press an annular spring 1 into face-to-face contact with a base-plate 5 while springs 7 displace each element 2 to the position shown in broken lines. During the closing movement of the valve, the elements 2 are displaced against the springs 7 by the spring 1 and cause the spring 1 and cage 6 to rotate the valve through its loading spring. In a modification, the spring 1 and cage 6 are held against rotation and the member 3 is adapted to rotate a conical valve guide. A stop 8 for the cage may be replaced by a lip 12, Fig. 5, a raceway may be interposed between the elements 2 and the spring 1, and the spring 1 may be replaced by an annular plate resting on coil springs. In Fig. 7, two spring elements 15a, 15b rest on a thrust bearing 16 and a brake disc 20 prevents rotation as the valve opens.
