IPC: G06F13/22
Filed: 1965-10-21
Abstract: 1,075,170. Digital computers; buffer stores. GENERAL PRECISION Inc. Oct. 21, 1965 [Nov. 23, 1964], No. 44624/65. Headings G4A and G4C. One track of a rotatable magnetic disc store forms a buffer between an electronic digital computer and its input/output devices. As shown, a disc 10 includes, in addition to. 32 normal data tracks (each divided into 128 thirty one bit words including spacer bits), a clock track (3968 unity bits), an index track (single unity bit) and a buffer track F which is. divided into similar sectors to the data tracks and is provided with its own read and write heads 22, 24 respectively. Different portions of the F-track are assigned to different ones of the input/output devices 30-40 and gating of these devices (through AND gates 56-66) to their corresponding track portions for data transfer is controlled by a seven position counter 42 responsing to index pulses from. index pulse amplifier 18 and to, end-of-word pulses from a binary bit counter 20 coupled to clock amplifier 14. Data may be transferred between any. part of the buffer track and the. computer arithmetic unit 70 under, control of a control unit 72. Transfer of data from the input devices can be inhibited by using the write control leads into gates 62, 64 and 66.

Abstract: 894,486. Ironing-tables. NEWBY, R. L. (Proctor-Silex Corporation). Dec. 30, 1960, No. 44729/60. Classes 52(1) and 52(3) In an ironing-table, a folding underframe has a single pair of wheels 32, 33 which are free to rotate only when leg 22 is inclined to the vertical. The wheels 32, 33 are arranged to be self-braking when leg 22 is in a substantially vertical position and the folded table is leant against a wall. An axle 34 for wheels 32, 33 extends through tube 29 and is journalled in plate 37 fitted in the ends of the tube. Each plate 37 has a hole 42 only part 43 of which is concentric with the axis of tube 29. When leg 22 is moved to the vertical position (Fig. 5, not shown) part 44 of the hole is higher than part 43 and the axle 39 is thus constrained to move towards part 44. The overlying rubber side wall portion 36 of wheel 32 is forced against tube 29 so that the wheel cannot rotate. Reference is made to an alternative form in which the wheels extend within the tube 29 and engage its inner surface. Tube 28 carries non-rotatable rubber cups 30, 31. The legs 21, 22 fold flat against the underside of the table top 20 which may be adjusted in height by the arrangement described in Specification 781,829.

IPC: H03M1/00
Filed: 1969-09-12
Abstract: 1286490 Incremental measuring systems DR JOHANNES HEIDENHAIN 12 Sept 1969 [12 Sept 1968] 45199/69 Heading G4H In an incremental measuring system in which signals T4, T5 phase displaced by 90 degrees are counted positively or negatively according to the direction of movement in a counter 9, there being four counting pulses for each cycle of one of the signals T4, T5, to detect errors in the count the signals are additionally fed to logic circuitry for comparision with the count. As described signals T4, T5 are derived from photo-cells 14, 15 sensing a grating 20, 11. A bi-stable 20 delivers a "1" or a "0" input to an exclusive OR gate 16 which receives at its other input the signal T4 so that the output signal on conductor 21 fed to an exclusive OR gate 17 is either in phase or out of phase with the signal T4 in dependence on the bistable output. The gate 17 also receives the signal T5 so that it delivers an output signal on conductor 22 at twice the frequency of the signals T4, T5 to an exclusive OR gate 18, the phase of the signal on conductor 22 is inverted by a change in state of the bistable. The gate 18 also receives a signal on conductor 23 representing the state of the lowest stage of the counter (that is representing the instantaneous count mod. 2) this signal being of twice the frequency of the signal T4, T5. When the signals on conductors 22, 23 are in phase no output is obtained from gate 18 but when they are out of phase a lamp 28 is lit and bi-stable 20 is switched to bring the inputs to gate 18 in to phase. The lamp is extinguished by operation of switch 30. A pulse forming unit 34 delivers pulses of logical value zero on conductor 41 at the edges of pulses from gate 17 to prevent errors of the switching instants of the counting pulses. Capacitors or conductive or magnetic scanning may alternatively be used.

Filed: 1961-12-19
Abstract: 975,420. Twin-lens reflex cameras. FRANKE & HEIDECKE G.m.b.H., [trading as ROLLEI-WERKE FRANKE & HEIDECKE]. Dec. 19, 1961 [Dec. 22, 1960], No. 45429/61. Heading G2A. A twin-lens reflex camera having a rearward extension attachment for increasing the distance between the objective and the film plane has an intermediate member to provide a corresponding displacement of the focusing screen with simultaneous off-setting of the screen in its own plane to correct for parallax between the exposure and view-finder objectives. The intermediate member may be a spacing member which is fitted in a detachable manner between the focusing screen and the top of the camera. This is then used for a specific fixed rear extension member which may be a roll-film cassette which fits on to the back of the camera and which may have a built-in developing arrangement. Alternatively the intermediate and rear extensions may be adjustable. As shown in Fig. 3, a film or plate cassette 19 is connected to the back 20 of the camera by bellows 21 and a lazy tongs system 22, the extension being controlled by knob 23.- The focusing screen and light-hood 13 are connected to the camera by frames 24, 25 and bellows 26 and are displaced backwards in the plane of the focusing screen to correct for parallax. The frames 24, 25 are connected-by lazy tongs 27 which are connected by arm 28 to lazy tongs 22 so that movement of the latter causes a corresponding movement of the focusing screen parallel to itself. In a further embodiment, the lazy tongs 27 are operated by a knob similar to knob 23, which knob is connected to knob 23 by a flexible shaft, and the arm 28 is dispensed with. In this embodiment the front arm of the lazy tongs 27 also carries a pin which works in an inclined slot in the front of frame 24, and a further knob causes the lazy tongs to move the focusing screen in its own plane.

Abstract: 1,038,087. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 6, 1962 [Dec. 20, 1961], No. 45610/61. Addition to 981,423. Heading G6C. In a boiling water nuclear reactor, the water acts on both coolant and moderator and a rapid fall in the water level is used to cause shutdown during fault conditions. The fall in water level is effected by reducing steam pressure to cause a more rapid boiling or " flashing." The reactivity falls in proportion to the increase in steam voids and the consequent reduction in the moderating effect as the liquid level is reduced. During " flashing " the excess steam is directed into a dump condenser through a valve automatically adjusted in accordance with the coolant level, temperature, reactor reactivity and period. The control is adjusted so as to leave the spiral water level adequate to conduct the " decay heat " from the core.
