Title: Improvements in or relating to digital to analogue converters
IPC: H03M1/66
Filed: 1966-10-17
Abstract: 1,102,120. Selective signalling. HONEYWELL Inc. 17 Oct., 1966 [18 Oct., 1965 (2)], No. 46261/66. Heading G4H. In a digital-to-analogue converter a reference and a data counter are caused to cycle continuously by the application of clock-pulses but the phase of the data counter is varied selectively, in accordance with input data, either by inhibiting some clock-pulses that would normally be applied to it or by applying additional pulses interleaved with the clock-pulses, to it, and the carry outputs of the reference and data counters are used to turn a trigger on and off respectively so as to produce a constant frequency pulse train whose mark/space ratio corresponds to the input data, which pulse train is then integrated to provide a corresponding amplitude significant signal. Error preventing means are included which prevent the phase of the data counter leading or lagging the phase of the reference counter by more than one cycle. In a modification means are provided for determining the mark/space ratio by counting clock pulses for the duration of a mark.

Abstract: 1375059 Fire alarms CONSOLIDATION COAL CO 6 Oct 1972 [12 Oct 1971] 46315/72 Heading G4N [Also in Divisions H1 and H2] A fire alarm comprises a heat-sensitive device (a bimetal strip 18) closing contacts 29, 31 at a predetermined temperature, contacts 29, 31 being on conductive strips 28, 30 projecting into a receptacle 40 and being soldered or welded to conductive strips 54, 56 having barbs 58 which when receptacle 40 is closed plunge into conductors 50 of a two-conductor cord. Receptacle 40 comprises a base 44 to which is pivoted by hinge 64 a top part 45 carrying the strips 54, 56 and latched closed by spring 66. A number of fire alarms T 1 , T 2 , T n , Fig. 3, are connected in parallel across conductors 50 and also in parallel with a resistor 102. Normally a small current flows through relays R1, R2 and resistor 102, sufficient to energize relay R2 to hold contact R2 open but not sufficient to energize relay R1. If this current is interrupted, e.g. by a cable break, relay R2 is de-energized, contact R2 closes and alarm A2 is energized. The electrical connections of each fire alarm can be tested by prods 76, Fig. 2, inserted through holes 70 in base 44, prods 76 being connected to a voltmeter 72. If a fire breaks out, one of alarms T 1 , T 2 , T n  closes  and the new current through relay R1 is sufficient to energize it and close retaining contact R1 and also a contact R1 to actuate alarm A1. After the alarms T 1 , T 2 , T n  reopen after cooling down, relay R1 is de-energized by reset switch 104.

Abstract: 1,225,073. Coaxial cable for radioactive environments. COMMISSARIAT A L'ERERGIE ATOMIQUE. 3 Oct., 1969 [10 Oct., 1968], No. 48811/69. Heading H1A. A coaxial cable for use in regions of high radiation density has an outer sheath made up of lead or lead oxide sandwiched between concentric cylinders of stainless steel, an insulator comprising a mixture of alumina and magnesia, and a conductive core made of iron, nickel or stainless steel. The proportion of alumina to magnesia in the insulator, and the dimensions and materials of the sheath and core are so chosen that under conditions of steady irradiation the sheath and core are not readily activated by neutrons, and the deactivation reactions in the materials of the cable do not lead to any nett current in it. To avoid excessive transients when irradiation ceases, magnesia or magnesium metal may be added to the material of the core.

Abstract: 1528914 Fluid-pressure servomotor systems MASSEY-FERGUSON SERVICES NV 17 Nov 1975 [18 Nov 1974] 49871/74 Heading G3P A swash plate 12 for an hydraulic machine 10 is adjusted by a servomotor 11 controlled by a valve 13 operated by a manually adjusted spindle 27 while a second valve 53 receives a signal dependent on the product of machine output pressure and displacement and adjusts the valve 13 through a piston 47 when a predetermined value of the product is exceeded. To provide the signal, delivery pressure from a line 9 is applied through a duct 84 to a piston 83 incorporated in a block 81 which is displaced along a rod 82 by a pin 86 on the swash-plate. The piston tilts a lever 77 pivoted at 78 so that one of a pair of studs 75, 76 on a second lever 73 pivoted at 74 is engaged. A bell-crank 71 transmits the movement of the second lever to the valve 53 and causes piston 47 to adjust the valve 13 through a rod 46, links 36, 22 and a roller 24 co-operating with guides in a lever 14 and a lever 28. The latter is coupled with the spindle 27 through a pair of studs 33, 34 and a spring 32 and is pivoted about a different axis from that for the lever 14 so that movement of the roller 24 rotates the lever 14 and shifts the valve 13 until the product of pressure and displacement is reduced to the original required value. In the preferred embodiment, a pair of machines 10 is provided and each spindle 27 has an operating handle 29a. The arrangement of the links 77, 73 transmits movement to the bell-crank 71 for movement of the swash-plate in either direction from neutral.

The device may be mounted in a CO 2  pressurized beverage tank 12, a sleeve 21, having apertures 25, 125 and encompassing part of the bore, locating a sliding plug 24 through which the tube 28 passes. The valve seat is also located in the sleeve whilst a further valve member 36 with top apertures (38), Fig. 2 (not shown), and bottom conical walls (40) is urged upwardly against a block 34 by a spring 37. When a gas valve 18, at the top of the counterpressure tube 28, is opened, CO 2  under pressure is applied to the bottle, this pressure, acting upwardly on the bottom surface of valve member 26, together with the force exerted by the spring 33 lifting valve member 26 off its seat 29, as in Fig. 3 (not shown) causing beverage to flow from the tank via the apertures 25, 125 and the space between block 34 and a shoulder 23, through the apertures (38) forcing valve member 36 downwardly, as in Fig. 4 (not shown), and through the annular space between walls (40) and (41), the distributer 71 causing a helical flow into the bottle 17. Beverage flow stops automatically when the counterpressure in the bottle is equal to the pressure in the tank 12. The spring 37 then closes valve member 36 and valve member 26 is subsequently closed mechanically.
