Title: Circuit arrangements of highly integrated chips
IPC: G06F12/06
Filed: 1974-12-19
Abstract: 1469298 Data processing OLYMPIA WERKE AG 19 Dec 1974 [22 Dec 1973] 54997/74 Heading G4A A circuit arrangement has a chip 1 including a computing and control unit, and a number of memory chips 3, 4, 5 each of which includes a memory and an associated address register 6, 7, 8, each having stages for addressing all the locations in the associated memory and further stages for receiving address bits which identify the different memory chips. Each address register 6, 7, 8 normally counts clock pulses, but an address supplied from the computing and control unit is written into the address registers 6, 7, 8 in parallel to identify a specific memory location in a defined chip. Each memory chip includes additional registers (32, 33, Fig. 2, not shown or 160-162, Fig. 5, not shown); if an addressed byte contains a jump instruction the jump address is transferred into the address register 6, 7 or 8, and one of the further registers (32 or 160) contains the interruption address plus 1; this is extended by the use of one or two further registers if the sub-program contains a jump instruction. The computing and control unit includes a logic unit (117, Fig. 4, not shown) receiving a first operand from a first register (122) and a second operand from a second register (123) or a random access memory (110). The random access memory may be addressed by two threebit registers (111, 112), one (112) of which receives counting pulses, or by four bits in an instruction register (114). If the instruction register (114) provides the address "12" to the memory (10) this indicates that the memory is to be addressed with the contents of the three-bit registers (111, 112). If the instruction register provides the address "13" or "14" to the memory this indicates that the memory is to be addressed with the contents of the three-bit registers and that one of these registers (112) subsequently counts backwards or forwards, respectively.

Abstract: 1482765 Fuel elements INTERATOM INTERNATIONALE ATOMREAKTORBAU GmbH and BELGONUCLEAIRE SA 19 Dec 1974 [22 Dec 1973] 55025/74 Heading G6C An arrangement for spacing a plurality of fuel rods within a nuclear reactor fuel element casing 1 comprises a spacer element 2 having a plurality of curved leaf springs 4 distributed over its periphery, the springs 4 being parallel to the longitudinal axis of the casing I and contacting its inside wall, both ends of each spring 4 being fixed to the spacer element 2, as by spot welds. Each spring 4 is preferably convexly curved in its central portion and concavely curved between its central portion and each of its ends, in relation to the spacer element. The springs 4 may then be disposed in grooves in the spacer element 2 so that only the convexly curved portion of each spring projects from the surface of the spacer element, the springs thus being protected from damage when the spacer element is being fitted into the fuel element.

Title: Apparatus for and method of making pads of fibrous material
IPC: A47L13/07
Filed: 1966-12-16
Abstract: 1,108,728. Fibrous pads. C. J. DEMRICK. 16 Dec., 1966, No. 56490/66. Heading D1R. [Also in Division B3] A method of making a pad of fibrous material comprises the steps of separating a ribbon of the fibrous material into strips, forming each strip into a roll having a generally rectangular, longitudinal cross-section, forming each roll in a direction along the axis into an intermediate pad having a generally circular longitudinal cross-section, and pressing the intermediate pad transversely to the circular cross-section to form a finished pad. A continuous ribbon of steel wool 20 is passed between pairs of toothed rollers 24, 25 and 26. 27 in a work station 22 and liquid soap may be sprayed onto the ribbon from a nozzle 88 before it enters therein. The roller pair 24, 25 is driven intermittently via a Geneva wheel 73, so that when stationary the ribbon is torn into strips 28 of predetermined length. The strips then pass through a work station 30 on a belt 34. A leaf 116 catches and folds back the leading edge of each strip 28 which is then formed into a roll 32 between the belt 34 and an adjustable pressure; plate 36. A curved plate 130 deflects each roll 32 in a work station 40 and a leaf spring 134 slows down the rolls to reduce bouncing when the roll hits die sets 48. As the roll falls, it interrupts a light beam between a light (302) and a photo-cell (304), Fig. 11 (not shown) and thereby actuates an air cylinder 172. The cylinder 172 is connected to a cam plate 170. on which the roll falls. The cam track 252 in the plate 170 drives a shuttle 178, which has semi-cylindrical ends 196, 198, to compress the roll between itself and a fixed die 200. which has semi-cylindrical faces 202, 206 cooperating with the ends 196. 198 respectively Figs. 7a, (not shown) 7b. A cam track 254 in the plate. 170 drives die plate 180 in the opposite direction to the shuttle 178. The plate 180 has lower halves 186, 192 of vertical dies attached thereto, which form the bottoms of receptacles into which the rolls 32 are pushed by the shuttle 178. A stop 244 on a rod 236 alternately drips air valves 246. 248 to actuate punches 153. 163 respectively so as to form pads 42. When the pad is formed. the following roll 32 interrupts the light beam to actuate the air cylinder 172 in the opposite direction and as the shuttle 178 and die plate 180 move laterally in opposite directions. the pad finished 42 is freed to fall onto a conveyor 50.
