Patent GB-653439-A (GB)
Abstract: 653,439. Ticket-issuing machines. TOTALISATORS, Ltd. (Automatic Totalisators, Ltd.). Oct. 16, 1947, No. 27716. [Class 106 (iii)] A selector assembly for a totalizator ticket issuing machine comprises a selection pointer casing 3 rotatable in a horizontal plane about a vertical axis, a stationary dial plate 1 associated with said pointer casing, a handpiece lever 9 fulcrummed about a horizontal axis for angular movement in a vertical plane, two brush fingers 20, 21 mounted on said lever, two arcuate rows of selector contacts 22, 23 associated with said brush fingers, and a thrust rod 12 manually movable, relative to said lever, between two positions to select one of two switches 43, 44 which are in circuit with the arcuate rows of contacts 22, 23 respectively. The invention is applied to the type of machine disclosed in Specification 441,422. and operates as follows. The pointer housing 3 is rotated about its axis until the nose 4 is coincident with the desired competitor number on an arcuate scale on the dial plate 1. This rotation is transmitted through a sleeve 6, a gear wheel 8 and associated gear train (not shown), to a competitor number type wheel and the two brushes 20, 21 are above the corresponding pair of contacts in the rows 22, 23 which rows correspond respectively to " win " and " place circuits. The rod 12 (if not already in the required position) is moved inwardly or outwardly so that through a bellcrank 31, a push-rod 34, lever arm 41 and a pin 42, the desired one of the switches 43, 44 is closed depending on whether the competitor is chosen for a win or place. Downward movement of the lever 9 will therefore through the brushes 20, 21, contacts 22, 23 and the already closed switch 43 or 44 select the " win " or " place " competitor integrator circuit. This downward movement is also transmitted to a tube 16 which effects closure of the integrator circuit and operates an interlock mechanism, not shown, whereby the lever 9 is kept down until a ticket is issued. The abovementioned downward movement of the rod 34 consequent to radial movement of the rod 12 serves through rods 38, 40 to select for operation " win " or " place " type wheels (not shown), and counters respectively.

Class 97(1) A stereoscopic instrument for plotting aerial photographs set parallel to the plane of measurement and having means which, in dependence on the co-ordinates of the point under observation, compensate the error due to central projection is characterized in that the distortion arising from tilt of the taking camera is at least approximately compensated by an arrangement which automatically adds a correction to the height or parallax value of the observed point obtained by the instrument which correction is a linear function of the co-ordinates x, y of the point. Fig. 3 shows a plotter in which the photographs I, II are on a table 10 movable in the x or y direction under measuring marks 12, 13, these movements being transmitted to a computer 15 by a rod 14. The distance between the marks 12 and 13 is varied, for plotting different heights by rotating a screwshaft 17 on which the mark 13 is carried; this rotation being communicated by a flexible shaft 19 to a differential gear 52 in a computer 20. The x and y components of the movement of the table 10 are also connected by the computer 20 by a shaft 21 which moves a slide 30, Fig. 4, in the x direction and a slide 31 in the y direction. Movement of the slide 30 is connected by a rod 34 and bellcrank 36, 37, pivoted at 35, to a bar 39 the position of which is adjusted by a screw 58 according to the constant W. Vertical movement of this bar moves the slotted bar 40 vertically which operates a rack to feed the movement into the differential 52. The rack is also moved vertically in accordance with the y co-ordinate by bar 41, lever 43 and rod 45 which is adjustable by a screw 63. The corrected parallax value emerging from the differential 52 is fed by a shaft 24 into the computer 15.

Patent GB-2018400-A (GB)
Title: Wedge gate valve
IPC: F16K3/18
Filed: 1979-03-19
Abstract: The valve includes a closure member- wedge assembly (30) with closure members (36, 38) engaging tapering faces (33, 34) of a wedge (32). Guide rails (60, 61) engaged by grooves (67) on the wedge extend longitudinally into the fluid passageway and terminate at ramps (64). The wedge (32) has transverse locking notches (76) which receive actuating rollers (73) in engagement with supporting surfaces of the closure members (36, 38). When the rollers (73) are in the locking notches (76) of the wedge (32) and engage the longitudinal edges of the guide rails (60, 61) they serve to lock the closure members (36, 38) to the wedge (32) thereby precluding lateral movement of the closure members (36, 38) during movement of the assembly between open and closed positions when the rollers (73) unlock the closure members (36, 38) from the wedge (32) by moving out of the locking notches (76) and out of contact with the rails (60, 61) due to the ramps (64) the wedge can move relative the closure members to force them sealingly against the valve ports, the closure members being restrained from further longitudinal movement by engagement with pins (78, 79). <IMAGE>

Patent GB-2038490-A (GB)
Title: Electrical Circuit Testing
IPC: G01R31/28
Filed: 1979-11-28
Abstract: A method of measuring parameters of an electrical circuit involves supplying a test signal to circuit terminals (1 to 4), which signal may be a pulsed signal, thereby to switch off a switch component (ZD1). When the circuit is in this condition, further test signals may be applied to the terminals (1 to 4) to measure other circuit components (11, 12, 13, ZD2). The method is particularly applicable to circuits, e.g. diode safety barriers, that are encapsulated and require testing after encapsulation, when only terminals (1 to 4) are exposed for connection into an external circuit. In operation, a current I1 is passed between terminals 1, 3 from a source 14, and is sufficient to ensure that the zener voltage of diode chain ZD1 is not exceeded. Current I2 applied at terminals 3, 4 by a source 15 then flows only through parallel diode chain ZD2 and current-limiting resistor 11. The voltage between terminals 3, 4 is then measured at two different values of I1 to allow resistor 11 to be measured, as well as the voltage drop across chain ZD2. Similar measurements at terminals 1, 2 with source 15A allow the resistance of a fuse 13 to be determined. <IMAGE>

Title: Interrupt system
IPC: G09G1/16
Filed: 1979-12-13
Abstract: In a system comprising a CPU4, memory 10 and first and second pluralities of peripheral devices coupled to a bus 16, interrupt request signals generated from the first plurality of devices (eg keyboard 8, CRT display 12) result in an encoder in the CPU generating a predetermined address which is sent out as the start address of an interrupt routine. If an interrupt is generated from the second plurality of devices (eg extend communications option 25 or peripheral options 14a-f) the device sends low order address bits, in response to an interrupt acknowledge signal from the CPU, which are combined with the high order address bits generated by the CPU to form the required routine address. <IMAGE>
