Title: Analogue-digital converter
IPC: H03M1/00
Filed: 1965-07-23
Abstract: 1,111,269. Analogue-to-digital converters. LICENTIA PATENT-VERWALTUNGS G.m.b.H. 23 July, 1965 [24 July, 1964], No. 31455/65. Heading G4H. In an analogue-digital converter, the input voltage is applied to a number of potential dividers, one for each digit of the output signal, each centre point being connected to a threshold device which when operated gives an output signal and causes additional resistors to be switched into the potential dividers of lower order digits. The threshold devices consist of transistors TrO, Tr1, &c. which respond when the voltage becomes zero or positive. The reference voltage + U is ten volts positive and the unknown voltage A is negative. The potential divider for digit 1 consists of resistor RO1 and rO, 1 in the ratio of 1/100. If the unknown voltage is 0À 1 volt or above, transistor TrO will conduct and operate output trigger TO. In parallel with resistor rO,1 are further resistors rO,2, &c., which may be switched into circuit under the control of triggers T1 &c. corresponding to higher digits. The embodiment illustrated is a two-decade, binary-coded decimal system. For an input voltage value of 0À5 volt, for example, the lowest three transistors TrO, Tr1 and Tr2 instantly respond. Trigger T2 switches resistors r1,4 into the " 2 " digit potential divider and rO,4 into the " 1 " digit potential divider. Trigger T1 switches resistor rO,2 into the " 1 " digit potential divider. These changes in the " 1 " and " 2 " digit potentiometers mean that 0À6 and 0À7 volts would now be necessary to operate the transistors Tr1 and TrO. Accordingly they both cut off and trigger T1 and TO reset. This causes resistor rO,2 to be switched out of the " 1 " digit potential divider so that the response level changes to 0À5 volts. Transistor TrO accordingly re-operates and sets trigger TO. Outputs are accordingly obtained from the " 1 " and " 4 " stages.

Abstract: 663,878. Metal-vapour lamps. BRITISH THOMSON-HOUSTON CO. Ltd. Dec. 6,1948 [Dec. 5, 1947], No. 31523/48. Class 39 (i). An electrical discharge device of the kind including an envelope containing an ionizable medium capable of supporting an arc discharge, and an unactivated hollow electrode providing the electron emission for the arc discharge and comprising a cylindrical portion positioned parallel to the discharge path and a substantially conical portion converging towards the end of the electrode which is connected to a coaxial lead-in wire, is characterized in that the side wall of the converging portion of the electrode is apertured to provide a gap in the surface of this wall, the width of which varies from point to point in the direction of the axis or generatrix of said wall or surface. A high-pressure mercury vapour arc lamp, wherein the arc is initiated by a glow discharge, comprises two main unactivated electrodes 3 and 4 and an auxiliary starting electrode 5 in the form of a refractory metal wire, which may be omitted if desired, mounted in a tubular vitreous envelope 2 having moulded ends somewhat reduced in diameter around the electrodes 3 and 4 and terminating in necks 7 and 8 which may embody graded seals, as shown. The electrodes 3 and 4 comprise a hollow cylinder 3, Fig. 3, of metal such as tantalum having one end slit to provide integral extension arms 19 which are bent so as to converge for connection to a lead-in wire 10. The arms 19 provide a diverging path of travel for a glow discharge, which may thus adjust itself automatically for the most favourable operating condition. On applying A.C. to the primary winding of the semi-auto type transformer 12, an auxiliary discharge starts across the gap 4, 5. This initiates a glow discharge across the main gap 3, 4, which in turn initiates the main arc discharge. Current flowing through the heating resistor 18 operates the thermal switch 17 which disconnects the auxiliary electrode 5. The gas filling comprises saturated or unsaturated mercury vapour and an inert starting gas such as argon, krypton or xzenon; argon at a pressure of 11 mm. of mercury being satisfactory.

Abstract: 446,109. Fastenings for lift gates. FOULDS, Ltd., E. A., and CATTERALL, H., Albert Works, Colne, Lancashire. Nov. 9, 1934, No. 32231. [Class 44] [See also Group XXX] Locking mechanism for lift gates &c. comprises a member the position of which is changed by the initial operation of the stopping and starting gear, and a rotary gate holding member the position of which is changed by the final closing and initial opening of the gate, but is held against rotation by an obstruction member when the lift is not stopped at a floor, the rotary member itself preventing the obstruction member from disengaging the starting mechanism when the gate is open. A gate can consequently only be opened when the lift is stopped at a floor and the lift cannot be started unless all the gates are closed. A casing a on the gate opening has a slot a<1> to admit the end of a catch bl on a sliding gate b and as the gate is closed the catch engages between teeth on a member c and turns it from the position shown in full lines to that shown in dotted lines. A rod i connected to the lift control cable is slidably mounted in the casing and has a V-notch i<1> to accommodate the enlarged end e<1> of a lever e loosely mounted on a spindle f. The lever e is connected by a spring h<1> and pin h to a lever g fixed on the spindle f and having an extension g<1> acted upon by a spring g<2> which urges the lever g, and with it the lever e, towards the position shown in chain lines where it engages beneath a projection c<3> on the member c when the gate is closed and prevents re-opening of the gate. The spindle f carries a second lever, not shown, carrying a roller jl adapted to be engaged by a ramp on the cage to move the lever e out of engagement with the projection c<3>, but unless the rod i is in the lift-stopped position so that the enlarged end e<1> of the lever e can enter the notch i the lever e is not moved, the spring h<1> merely being compressed. When the lift is stopped and the gate is open the member c prevents the lever e from being moved into the position shown in chain lines and consequently the rod i cannot be moved to start the lift. The rods i at each floor of the lift shaft may be connected by links l, Fig. 3, to a bell-crank lever m which is linked to a bell-crank lever n acted upon by a cam o on a pulley d. The control cables p are passed around this pulley and around tensioning pulleys q. The cable also passes around a pulley r having a cam s acting upon the lift control lever t<1>, the cam being so formed that the lift is only started or stopped when all of the rods i have been moved. The locking members may be duplicated on the opposite end of the lift, as shown, when gates are provided at each end of the lift.
