Patent GB-1375029-A (GB)
IPC: G06F17/16
Filed: 1971-12-23
Abstract: 1375029 Vector computing system TEXAS INSTRUMENTS Inc 23 Dec 1971 [4 Jan 1970] 60072/71 Heading G4A A circuit, e.g. in digital electric computing system, is adapted to compare elements of two vector streams and to produce an ordered third vector stream. A vector x is defined as the ordered array of elements (X 1 , X 2 , X 3  ... Xv(x)). X 1  is the ith component of vector x, and the number of components V(x) is the dimension of X. A numerical vector X may be multiplied by numerical quantity k to produce the scalor times vector multiply kxX (or kX) defined as vector z where Z 1  = kxX 1 . A matrix M may be formed from a two dimensional array of elements. The hardware shown is part of the computer arthmetic unit and the inputs and outputs thereto lead to the memory buffer unit. The two streams A and B send respective first elements to registers 15 and 17 and thence to registers 19 and 21 where they are compared by comparator 29. If the A element is greater than the B element, the A element goes via register 23 and gate 24 back to register 19 and the B element goes to output register 27 as the first element of the third stream. The first A element is then compared with the second B element and so on. If a B element is greater than an A element, the A element passes via gate 26, registers 21 and 25, to the third stream while the B element passes to registers 23 and 19. Hexadecimal and decimal numbers are also mentioned.

Title: Semiconductor switching circuit
IPC: H03K17/10
Filed: 1978-06-16
Abstract: Owing to a semi-conductor switching element (with a switching path and a control electrode) having a break- down voltage, circuit arrangements comprising a plurality of such elements connected in series having to be used for application to high-voltage circuits. Power losses can become substantial, especially when the switching frequency of the circuit arrangement is increased. Improved operation can be achieved by connecting between one end of the path and the control electrode of each switching element a voltage limiting element and an electronic switch connected in series, whereby to limit the value to which the voltage will rise across each switching path on switching off the switching elements. Each electronic switch closes simultaneously with interruption or reversal of the control electrode signal, and all the switches open after the limiting values of all the voltage limiting elements have been reached. <IMAGE>

Title: Packaging elements
IPC: B65D59/08
Filed: 1979-12-31
Abstract: A packaging element, for example a shock-resisting end cap for an article, is made from a pad (10) of foamed rubber or plastics, preferably closed-cell foamed polyethylene. Parallel to each edge a plurality of colinear score lines (11 to 18) are cut into one face of the pad, and between adjacent ends of each pair of colinear score lines the material is cut through to make formations (21), preferably of dovetail shape. Also, cuts (25a and 27a) are made between adjacent edge portions (24 to 27). To set-up the packaging element the edge portions (24 to 27) are turned through 90 DEG  about their respective hinges formed by the scoring. The dovetail formations (21) leave apertures in the central portion (22) but because of their shape resist return to the apertures and thus hold the element in its set- up condition. in an alternative embodiment (Fig. 4) wherein the formations are rectangular in plan, the turned edge portions are held in position by strips of stiff card bridging the apertures formed in the central portion. <IMAGE>

Title: Lubricant Dosing Valve
IPC: F16N27/00
Filed: 1980-03-13
Abstract: A dosing valve comprising a housing (1) having an inlet port (4) and an outlet port (5) and divided internally into first and second chambers (18 and 14) by a movable member (6) having an elastically deformable portion (11). The first chamber (18) is in permanent communication with the inlet (4), and the second chamber communicates with the outlet (5) via a spring loaded non-return valve (19), which is adapted to be closed by movement of the movable member towards the outlet and to be opened when the pressure in the second chamber (14) reaches a predetermined level. The first and second chambers are arranged to communicate via a control port (15, 16) which is adapted to be closed by movement of the movable member (6) towards the outlet (5). In operation, with the valve filled with fluid at low pressure, an increase in pressure at the inlet causes the movable member (6) to move towards the outlet (5) so as to shut off the control port (15, 16) between the chambers and the outlet valve (19, 20), and a further increase in inlet pressure and therefore in the first chamber causes the elastically deformable portion (11) to deform so as to pressurise the second chamber and thereby open the outlet valve to deliver the dose defined by the second chamber (14). <IMAGE>
