Title: Improvements in or relating to data transmission systems
IPC: G11C11/06
Filed: 1964-06-29
Abstract: 1,061,265. Magnetic stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 29, 1964 [June 28, 1963], No. 26782/64. Heading G4C. [Also in Division H3] In a data transmission system, a group of bits is presented via array means to output means which combine the bits differentially in groups of at least two to minimize noise, coding means being connected to the presentation means to code the group complementary in effect to the coding in the output means. A binary word from a register (120) is recoded by EXCLUSIVE OR gates (121-1 to 121-n) a typical one of which receives one input from the corresponding stage of the register and one input from the output of the next-lower-order gate. The gate outputs are stored in a selected column (104-1 to 104-n) of a magnetic core (or film) matrix. On read-out, in order to reduce read-out noise, the matrix outputs are fed in pairs to differential amplifiers (A) each output going to two amplifiers. Since these amplifiers each perform an EXCLUSIVE OR function, the output of the amplifiers is in the same code as the original data in the register (120). Besides an input from the register (120), the lowest order gate (121-1) receives a reference voltage representing " 0 " on its other input, and each column of the matrix also has an extra core (or film element) storing " 0 " which provides one input to the lowest-order amplifier (106-1) during read-out. The register (120) and gates (121-1 to 121-n) may be interchanged in position. Data read from the matrix may be re-entered via the register (120).

Filed: 1937-10-06
Abstract: 498,618. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and ROSE, W. R. Oct. 6, 1937, No. 27016. [Glass 40(iv)] In a telephone impulse sender capable of emitting a group of impulse trains characteristic of the station, an example of which is described in Specification 466,301, the shaft 56, Figs. 3 and 4, carrying the operating handle, causes rotation of a shaft 41 by the engagement of a pivoted pawl 46 carried by the shaft 56 with a rocking pawl 43 pivoted on a member 42 secured to the shaft 41. This shaft is secured to a toothed wheel 45 which co-operates with impulse springs to emit a predetermined group of impulse trains as the shaft returns to a normal position after tripping of the pawls. The pawls are tripped when the projection 61 on the rocking pawl 48 encounters a fixed stop 64. The angle through which the shaft 56 can be turned is limited in both directions by a projection 54 on the member 49 and a stop 55. Another projection 57 on the member 49 engages with a projection 59 near the end of the operating movement to close contacts which enable impulsing to commence. In the modification shown in Fig. 1, the pivoted pawl 9 is carried by shaft 10 which is driven by a handle 1 through a toothed sector 6 and a gear wheel 8. The rocking pawl 11. is in this case pivoted to a toothed wheel 12 which is free to move relatively to the shaft 8 and is returned by a spring to a normal position determined by engagement of two stops, one 15 fixed to the case. and the other 16 fixed to the wheel 12. At the end of the operating movement a projection 21 on the pawl 11 engages a stop 23 and the wheel 12 is freed to return to its normal position. A governor 20 is driven by the wheel 12. To ensure that the handle 1 is always fully depressed before impulses are produced, a full-stroke pawl 28 and spring 26 are provided on a bracket 29.

Patent GB-866282-A (GB)
Title: Improvements in shifting registers
IPC: G11C19/28
Filed: 1957-08-30
Abstract: 866,282. Stepping registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 30, 1957 [Sept. 4, 1956], No. 27373/57. Class 106 (1). An electronic shifting register comprising a plurality of bi-stable trigger elements (stage 1, stage 2, stage n, Fig. 1) and a plurality of coupling devices (capacitors 22, 22a, 22n) arranged to connect said trigger elements together in a cascade chain, is characterized in that each coupling device includes an impedance having one terminal connected to a first pulse source and another terminal connected to a second pulse source, said pulse sources being synchronized to delivery simultaneously pulses of opposite polarity. As described each stage is constituted by a transistor flip-flop and is coupled to adjacent stages by a capacitor such as 22a. Each stage, for example stage 1, is referred to as " off " when transistor 24 is conducting and " on " when transistor 26 is conducting. When stage 1 is off (transistor 24 conducting) its base, point D, is at about 1.5 v. and the emitter of transistor 26, point E, is at 0 v. In these circumstances a negative common sync. pulse (going from 0 to - 5 v.) on the common sync. source line has no effect on stage 1 because it is blocked by a diode 25. When stage 1 is on, however, points D and E are at 0 v. and - 5 v. respectively and a negative common sync pulse allows point E to drop point D to - 5 v. thereby rendering transistor 24 conductive and turning stage 1 off. Thus the effect of a common sync pulse by itself is to turn every on stage off. Considering now the coupling capacitor 22a between stages 1 and 2, when stage 1 is on point F falls to - 5 v. and a positive forward shift pulse (from - 5 v. to 0 v.) on the forward sync source line will raise point F to 0 v. thereby applying a positive pulse to the base of transistor 24a tending to cause transistor 24a to become non-conducting that is tending to turn stage 2 on. When stage 1 is off point F is already at 0 v. and a forward shift pulse has no effect. Thus each forward shift pulse, by itself, will transfer any on state to the next adjacent stage. However the forward shift pulses and the common sync pulses occur together and the net result of this is that each stage only receives a pulse if it has to change its state. Thus when stages 1 and 2 are both off neither the common sync pulse nor the forward shifting pulse has any effect on point G, when stage 1 is on and stage 2 off the forward shifting pulse causes point G to rise and turn stage 2 on; when stage I is off and stage 2 is on, the common sync pulse drops point G and turns stage 2 off; when stages 1 and 2 are both on the forward shifting pulse tends to turn stage 2 on and the common sync pulse tends to turn stage 2 off, the result being that point G is unaltered in potential and stage 2 remains on. Entry of data to the register can be either serial via an input stage 10 or parallel via entry terminals 35, 35a, 35n. A second embodiment is described (Fig. 3, not shown) in which reverse shifting is also possible.

Abstract: 738,836. Valves. DEWRANCE & CO., Ltd- Oct. 30, 1953 [Oct. 31, 1952], No. 27413/52. Class 135. A valve, suitable e.g. as a blow-down valve for a steam generator, comprises a body having a fluid inlet 7, Fig. 1, and an outlet 8 connected by a bore 2 the flow through which is controlled by gate-type closure members 25, 26 disposed in series and actuated through rack members 30, 46 reciprocated by pinions mounted on shafts 92, 93 operable so that the valve member 25 nearer the inlet 7 opens before and closes after the valve member 26. The shafts are actuated through crank arms 122, 140, Figs. 3, 4, secured to the ends of the shafts 93 and 92 respectively and having pins 128, 141 carrying rollers disposed in a cam slot 168 in a disc 167 secured to the valve-operating spindle 158 which carries a hand-wheel. The cam slot comprises arcuate ports 168a, 168b concentric with the axis of the disc 167 and connected by a port 168c which effects the operation of the shafts 92, 93. With both valves closed, the crank arms 122, 140 are in the positions shown in Fig. 4, but upon anti-clockwise rotation of the valve spindle 158, the arm 122 on the shaft 93 remains at rest while the arm 140 on the shaft 92 moves clockwise, thus rotating the shaft to open the valve member 25. When the port 168a of the cam slot reaches the pin 128 the arm 122 is moved anticlockwise so as to open the valve member 26. Upon reversal of the direction of rotation of the valve spindle, the valve member 26 is closed before the member 25. Specification 204,804, [Class 122 (v)], is referred to.

Abstract: 1398012 Linear hydraulic motors VYZKUMNY USTAV OBRABECICH STROJU A OBRABENI 12 June 1972 27415/72 Heading F1A A linear hydraulic motor comprises opposed pairs of piston-and-cylinder units 30, 31 .... 38, 39 sequentially operated to cause relative movement between a body 3 which includes the units and a cam plate 1 against which rollers 20- 29 are urged by the units. The supply to the pairs of units 30, 31 .... 38, 39 is controlled by slide valves 50 .. .. 54, respectively, the valves being carried by the body 3. Each slide valve receives hydraulic fluid through whichever of channels 56, 57 is pressurized. This in turn depends on the position of a slide valve 59 urged to its mid position closing both channels but being displaceable therefrom by a pressure differential across its ends. The differential is established in dependence on the value of electric signals applied to magnets 60, 61 which position a reed 62. The reed 62 cooperates with nozzles 63, 64 through each of which escapes a throttled flow from a source at a pressure PO. Thus whichever of the nozzles is the more obturated by the reed 62 will determine the sense of the differential applied to the ends of the slide valve 59. A cam member 2 fixed to the cam plate 1 co-operates with the slide valves 50-54 to cause their changeover. The rollers 20-29 are mounted on bodies 70-79 slidable in bearings 80-89, the bodies being movable by the pistons 30-39. In a second embodiment Fig.2 (not shown), a rotary valve replaces the slide valves 50-54 and the rollers are mounted on cylinders (140-149) which slide on pistons (130-139) carried by the body 3, a rack (158) fixed to the cam plate 1 driving a pinion (157) on the rotary valve. In a third embodiment the cam plate 1 is in two parallel parts (201-202) with the piston and cylinder units arranged therebetween.
