Title: Electrical liquid-contact switches
IPC: H01H29/20
Filed: 1940-10-09
Abstract: 544,435. Mercury switches. O'BRIEN, J. F. Oct. 9, 1940, No. 15051. Convention date, Oct. 26, 1939. [Class 38 (v)] A mercury switch is rotated in steps, in one direction by manual operation through gearing connected to a reciprocating plate, there also being means for determining the degree of rotation at-each operation. In the example, a push button 10, or pull chain, operates a bellcrank lever 39, the other arm of which slides back a plate 35 against the pressure of a spring 38, pulling, through a' lost-motion connection, 35a, 34b, a hooked drag-link 34 to move one of four studs 33 on a gear wheel 31 meshing with another 23, in a ratio of two to one, secured to a rotary mercury switch 21. Unless the pull is sufficient to take a stud past the pointed end 35b of the plate, on release of the button &c. the return of the plate will return the mercury unit. The unit 21 is of the type having two metal cups 21a, 21b joined at their edges by an' insulating disc 21c with an aperture 21<SP>1</SP> enabling mercury on the two sides to make contact. One cup 21a is driven through a locating feather 21e on metal seating aid secured to a stud 22 spring - pressed by a contact blade 24 on a conductor 25. The other cup 21b rotates on a pressed-out button 26<SP>1</SP> on a yoke 26, the arm 27<SP>1</SP> of which is wedged in a spring clip 28 on the other conductor 29. The casing lid 11d may have a window through which an indicator lamp 14 can be seen. Preferably this is a neon lamp and the mounting and connecting parts 46, 47 are arranged that either electrode can be brought near to the window by rotating the lamp. Lugs from these parts engage spring clips on the conductor wires such as 29, embedded in the casing, when the switch is used with sectional conductor wiring.

Abstract: 878,085. Checking arrangements for magnetic drum data stores. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. April 23, 1959 [May 12, 1958], No. 15202/58. Class 106 (1). Information read at R1 from track 1 of a magnetic drum store is written back into its original position at W1 after processing at M1 (as described in Specification 826,230 in connection with telephone charge registers) a delay track 2 with write and read heads W2, R2 providing the appropriate delay and an erase head W3 preventing delay track information being read more than once in the event of failure of write head W2. Switches TS enable the delay track to be associated with any of a number of main tracks, and a unit Z detecting unsatisfactory read-out (as by failure of write head W2) then inhibits writing at W1. Fig. 3 (not shown) illustrates a modification in which information from R1 in addition to being entered at W2 is processed by a unit identical with M1 and the result entered on a sector of track 2 to be read off and compared with the processed data reentered by head W1, any discrepancy giving an alarm and preventing further writing at W1. Fig. 4 (not shown) illustrates the simultaneous use of a number of sectors of delay track 2, one for each of a number of main tracks. Specification 868,317 also is referred to.

Title: Analogue information storing device
IPC: G11C27/02
Filed: 1965-04-09
Abstract: 1,086,249. Electric selective signalling. INTERNATIONAL STANDARD ELECTRIC CORPORATION. April 9, 1965 [April 14, 1964], No. 15240/65. Heading G4H. [Also in Division H4] A multiplex analogue to digital converter comprises feedback loops for correcting losses in the circuitry. In the embodiment described 25 analogue signals are time-division multiplexed, channel 25 comprising a reference voltage equal to half the maximum analogue voltage range. The multiplexed signal passes via a storage capacitor and summing circuit to the converter which provides a serial-bit output. Due to variations in circuit parameters the voltage appearing at the converter input during channel 25 may not equal the reference voltage. To correct for this the most significant digit of the converter output during channel 25 is stored and controls a circuit which generates a positive or negative bias, as appropriate, over the next frame period, the bias being added to the analogue signals by the summing circuit. The second feedback loop counteracts the discharge of the storage capacitor during each channel time slot by comparing the state of charge of the capacitor at the beginning and end of channel 25 time slot. The store fed by the converter output controls a bias-generating circuit which responds to the -relative magnitudes of the most and least significant digit during channel 25 and passes an appropriate bias to the storage capacitor for the duration of one or more frames.
