Title: Memory organization
IPC: G06F7/02
Filed: 1964-08-17
Abstract: 1,059,268. Electric digital data-storage. SPERRY RAND CORPORATION. Aug. 17, 1964 [Aug. 29, 1963], No. 33560/64. Heading G4C. In a data storage device, whenever new data is to be entered in a location, the data previously stored in that location is sensed and compared with the new data, the write circuits being effective only in those bit positions where the new data and the old data differ. The repeated overwriting of identical data, which overwriting tends to produce undesired " creep " in magnetic thin film memories, is thus obviated. The memory described is a thin film wire memory (but may be a thin film plane or a magnetic core memory) one storage element 12 and its associated logical circuitry being shown in Fig. 1. To effect a write operation, the content of the memory element 12 is sensed, a flip-flop 22 being set if a " 0 " is stored, thereby inhibiting a NAND gate 20. The input bit is now read into flip-flop 24 and if the input digit is a " 1 ", a NAND gate 18 is enabled to cause a driver 14 to write a " 1 " in the memory element 12. If the input digit is a " 0 ", the gate 18 is inhibited and no writing into the element 12 takes place. The circuit is also effective to prevent overwriting of a " 1 " if a " 1 " is already stored in the element 12.

Title: Improvements in the construction of jetties, breakwaters, quays and other structures
IPC: E02B3/06
Filed: 1921-12-16
Abstract: 185,081. Constan, P. A. J. M., and Standaert, C. Aug. 26, 1921, [Convention date]. Breakwaters and the like.-Jetties, breakwaters, quays, &c. are constructed from hollow caissons of reinforced concrete, which are socketed, irreversibly wedged, and interlocked so as to form a solid and rigid structure. The socketing is effected by deep wedges of an angle less than 70‹. In constructing a jetty, three caissons M, N, P are employed having their ends formed as shown in Figs. 1 and 3, to provide the interlock. The caissons are hollow and are floated, the ends being then brought into proper relation and wedged by means of hydraulic jacks placed at the ridges of the wedges X; the jacks have cross-bars x, which can be turned vertically to enter the recesses C and then turned horizontally to lock the caissons together. The caissons are then permanently connected by metal framework and concrete which enter slots a, a<1>, #, #<1> and the recesses C in the ends of the caissons, and the jacks are removed. The jetty is then sunk on a prepared site, anchored thereupon by a device as shown in Fig. 5, or by a similar device, and filled with concrete, rock, &c. The construction also may be applied to submarine tunnels.

Abstract: 1,187,035. Controlling guided missiles. BRITISH AIRCRAFT CORP. Ltd. 1 Aug., 1967 [2 Aug., 1966], No 34692/66. Heading B7G. A missile adapted to be launched from a tube and subsequently steered during flight comprises an elongate, cylindrical body 2 having two diametrically opposed pairs of swept-back fins 6, each fin of which is retained in a folded position flat against the body 2 by the launcher tube (30, Fig. 3, not shown) and, as soon as the missile leaves the tube, is, due to air pressure acting on the fin, first erected to a position with the plane of the fin transverse to the longitudinal axis and then rotated through 90 degrees about a radial axis to a fore and aft aligned position, subsequent movement of the fin about the radial axis in order to steer the missile being effected by an electric motor 24. The fin is pivoted by a pin 12 to one of two hubs 10, journalled in opposite sides of the body 2, and is locked in the erect position (Fig. 5, not shown) by a lug 14 on the fin which co-operates with a spring-loaded detent 16 housed in the hub. The oppositely disposed hubs 10 are linked together by a bar 11 to provide a mounting member 8 which is rotated by the electric motor 24 coupled, by gearing 26, to a toothed quadrant 22 fast with one of the hubs. The radial axis about which the fin is caused to rotate constitutes an extension of the axis of the mounting member 8 and intersects the root 7 of the fin at midchord Due to the sweep-back angle of the fin, about 15 degrees, the centre of pressure of the whole fin is therefore off-set from the radial axis, in the rearward direction and provides the moment for rotating the fin. The missile is provided with foldable tail fins (4, Fig. 1, not shown) and longitudinal ribs (28) to guide the missile in the launcher tube.
