Patent GB-823609-A (GB)
Title: Improvements in or relating to delay storage device
Inventor: WOODS-HILL WILLIAM
IPC: G11C19/04
Filed: 1956-04-24
Abstract: 823,609. Electric digital-data-storage apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. March 19, 1957 [April 24, 1956], No. 12499/56. Class106 (1). Apparatus for registering input signals comprises a plurality of storage stages which receive the input signals over a common line, a pulse distributer having a plurality of output lines supplying control signals to the storages in turn, means operated upon coincidence of input and control signals to set associated storage stages, and means for reading out the settings in succession to a common line. As shown in Fig. 1, data entering in the form of a series-mode pulse train on line 2 is fed in parallel to all stages 1(a) . . . 1(d) of the store, distribution being effected by a pulse generator 6 which selects the stages in turn. Read-out on line 3 is also controlled by the distributer. All the stages can be re-set by a signal on line 5. In a more detailed embodiment saturable magnetic cores are used as the storage elements, each being settable either to two states or, as described in Specification 767,005, to ten states (Fig. 7, not shown). As shown in Fig. 2, data in the form of a binary pulse train passes through a gate 31 under control of a clock pulse source 32, and is applied to all the input windings 42(1), 42(2) .. 42(n) of a series of saturable magnetic cores 41(1), 41(2) . . . 41(n). The opposite end of each winding is connected to a pulse distributer 33 via a diode 26(1), 26(2) ... 26(n) which is normally blocked, but the diodes are unblocked by the distributer in succession to allow entry of significant digits by reversal of corresponding cores. The distributer subsequently supplies pulses of read-out current to successive cores via further diodes 27(1), 27(2) ... 27(n); this gives rise to a complemented pulse train in which the re-setting of each core storing a significant digit is represented by the absence of a pulse. This pulse train passes via a gate and complementer 34 to a utilization device. This read-out is destructive, but in a circuit using additional diodes (Fig. 3, not shown) a non-destructive read-out is achieved. Arrangements are also described whereby read-out can be started before read-in is completed, and may be performed in a different order. This last facility is accomplished by employing delay elements in the circuit.

Title: Improvements in or relating to Automatic Fire-arms.
Inventor: GORACUCHI FIORENZO DE
IPC: F41A3/26
Filed: 1918-08-06
Abstract: 123,002. Goracuchi, F. de. Aug. 6, 1918. Machine guns.-Relates to recoiling - barrel automatic guns with rotating and sliding breech-blocks, and consists in (1) forming the breech frame or casing with two camslots, one for rotating the breech-block and the other for rotating the firing pin to bring it into the cocked and firing positions, (2) providing a sleeve co-acting with the firing-pin to effect automatic firing, and acting as a safety device, and (3) special cartridge-feed mechanism. In the construction shown, the breech-block c, Figs. 8 and 9, which is locked to the barrel extension or breech-body b by forward locking-lugs f, g, has an arm m, projecting through a cam slot 3, 4, Figs. 1 and 5, in the breech-frame a. The firing-pin l, s, Figs. 12 and 13, has a stud t engaging a doubletracked slot 15, 16, 6<1>, 7, 8, 16, Fig. 5, in the breech-frame. Mounted on a tubular extension i at the rear of the breech-block is a sleeve m, Figs. 8, 14, and 15, which is prevented from rotating by a stud p .engaging a straight slot 5 in the breech-frame. The sleeve is formed with a slot o into which a rib x, Figs. 12 and 13, on the firing-pin enters when the firing-pin is in its foremost position. The firing-pin is also formed with a projection r having a cam surface engaging a corresponding cam surface j, Fig. 16, forming one edge of a recess in the tubular extension i of the breech-block. When the barrel recoils, the breech block is rotated and unlocked by the cam slot 3, and during this rotation, the firing-pin is retracted by the action of the two cams j and r. During the further recoil of the breech-block, the firing-pin is rotated by the inclined slot 6<1>, Fig. 5, so that the rib x bears against the rear edge of the sleeve n. On the return movement, under the action of the spring V, the breech-block is rotated and locked by the cam slot 3, and the firing-pin is rotated by the inclined slot 16, Fig. 5, to bring the rib x into engagement with the slot o in the sleeve n, whereupon the firing-pin completes its forward movement and fires the gun. The cartridges are raised into the loading position by a spring 30, Fig. 18, fixed at its rear end to a non- recoiling part 24 and at the front to a bar 22 which recoils with the barrel and breech frame b, the effect of the recoil being to bend the spring upwards and so raise the cartridge. A spring catch 26, by engaging a notch 25 in the bar 22, limits the recoil of the barrel and retains it in its rear position. The catch is released during the return of the breech-block and firing-pin by a projection 29 on the firing-pin.

Abstract: 1,042,721. Universal joints. LOHR & BROMKAMP G.m.b.H. April 1, 1963 [March 30, 1962; April 2, 1962; March 15, 1963], No. 12899/63. Heading F2U. In a constant velocity ratio universal joint of the kind having torque transmitting balls 29 in grooves 27, 28 in outer and inner members 25, 21, relative axial movement between the inner and outer members 21, 25 is permitted. As shown in Figs. 2 and 4, the balls 29 are retained in a part-spherical cage 30 between a cylindrical surface 26 of the outer member 25 and a spherical surface 31 of the inner member 21 and the axes of the grooves 27, 28 are oppositely indined to a plane through the joint axes, Fig. 5 (not shown). A small gap is preferably provided between the inner member 21 and cage 30 so that during axial movement of the outer member 25 the balls 29 roll until the cage 30 abuts the inner member whereafter the outer member slides relative to the balls. Axial movement between the inner and outer members 21, 25 is limited by a ring 32. In Figs. 1 and 6 (not shown), the outer surface of the cage has a central spherical part and outer conical parts which limit the angularity of the joint. In Fig. 7, the inner surface of the outer member 42 has a central cylindrical part 41 and outer spherical parts 43 which limit the axial movement of the jiont, and the inner member 45 has two part spherical surfaces 48 which permit greater rolling of the balls during axial movement between the inner and outer members. The axes of adjacent grooves in each member may be oppositely inclined to the plane through the axis, Fig. 8 (not shown). In a double joint, Fig. 10 (not shown), the axes of the grooves are arcuate, lie in a plane through the axis and are curved about centres which are axially spaced along the axis so that the grooves open in the form of an arcuate wedge, alternate grooves opening to opposite sides of the coupling members. The Specification describes an embodiment in which the axes of the grooves are straight, lie in a plane through the axis and are inclined to the axis so that the grooves open in the form of a wedge, alternate grooves opening to opposite sides of the coupling members. The axes of the grooves may be portions of helices, the helices on the inner and outer members having opposite pitch or pitched to the same hand with different lead. In Fig. 1 (not shown), the axes of the grooves are parallel with the axes of the coupling members.

Title: Magnetic-tape-record apparatus
IPC: G11B27/22
Filed: 1975-03-27
Abstract: 1492835 Tape transport control SHARP KK 27 March 1975 [28 March 1974 3 April 1974] 13097/75 Heading G5R [Also in Division H2] Magnetic tape apparatus has a tape drive motor 10, a recorded passage detection circuit 7 coupled to a tape head 2 and arranged when actuated by a manually operable switch 12 to produce a recorded passage detection signal when head 2 senses the presence of, and reproduces, information recorded on the tape 1, the detection signal ceasing if the signal from head 2 ceases for more than a predetermined period, and a circuit 9 controlling the motor 10 so that the tape speed depends on the production of the detection signal, the motor 10 rotating at a first speed when the detection signal is produced and at a second speed when the detection signal is not produced. During normal playback, signals reproduced by head 2 from tape 1 driven by motor 10 at playback speed pass via equalization amplifier 3, volume control 4 and amplifier 5 to loud-speaker 6. If a playback signal is present at the output of amplifier 3 when switch 12 is momentarily closed, circuit 7 gives an output to squelch circuit 8, thereby muting amplifier 5 and an outputto motor control 9 whereby motor 10 feeds the tape at fast forward speed until head 2 senses a silent period lasting for greater than a predetermined period, at the end of which predetermined period the output of circuit 7 ceases and tape playback at normal speed recommences. The length of said predetermined time period is set by an R-C circuit (22), (21), Fig. 3 (not shown), in detector circuit 7 which also includes an SCR (30) fired by momentary operation of switch 12 to turn on a transistor (28) and an LED indicator (29) for as long as head 2 provides a playback signal having silences shorter than said predetermined period. Motor control 9 has a conventional servocircuit (69), Fig. 5 (not shown), in which a transistor (65) has its loop gain altered, to cause motor 10 to feed the tape at a fast forward speed determined by the setting of a resistor (70), when a transistor (71) turns on in response to the input, at (73), to circuit 9 of the output of circuit 7. When the output of circuit 7 ceases, servo circuit (69) returns to its normal state and the motor 10 is decelerated by being shunted by a transistor (76) for a period set by R-C circuit (80), (81). When a power switch (74) is initially turned on, operation of braking transistor (76) is inhibited by means of a transistor (77) for a period set by R-C circuit (78), (79) having a longer time constant than circuit (80), (81).
