Title: Improvements in or relating to automatic electric signalling systems
IPC: G08B25/00
Filed: 1931-11-05
Abstract: 372,249. Electric signalling systems. KIDDE & CO., Inc., W., 140, Cedar Street, New York, U.S.A.-(Assignees of Grant, H. C. ; 470, West 159th Street, Manhattan, New York, U.S.A.) Nov. 5, 1930, No. 33434/31. Convention date, Nov. 21, 1929. Divided on 371,954. Drawings to Specification. [Class 40 (i).] Relates to an electric signalling system, more particularly a fire-alarm system, wherein when any one of a plurality of switching devices connected in a single circuit is operated an alarm device is actuated. The system described is identical with that described in Specification 371,954, but the invention resides in the provision of means for supervising the alarm device. Normally the alarm is connected in series with a relay having high resistance and a small current flows through the circuit to effect supervision. In the event of a fault, cessation of the supervisory current causes release of the relay and operation of a trouble bell and lamp indicator. The trouble bell may be switched out by a manually-operated switch. When the main signal is sent, a relay is energized to operate the supervised alarm, the highresistance relay being short-circuited and the circuit of the trouble alarms being opened to prevent operation. Specification 372,248 is referred to.

Title: Magnetic core registering system
IPC: G06F7/52
Filed: 1954-11-22
Abstract: 788,994. Electric digital-data-storage apparatus; electronic counting-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 22, 1954 [Nov. 25, 1953], No. 33712/54. Class 106 (1). [Also in Group XXXIX] In a magnetic core registering system comprising two cores each having co-operatively associated therewith an input, an output and a drive winding, and core-coupling transfer circuit means comprising a unidirectional conducting device, a condenser and a resistor, the unidirectional device and the output winding of one of the cores being connected in series across the condenser, and the resistor connecting the condenser to the input winding of the other core, the drive windings of both cores are included in the discharge circuit of a further condenser associated with a thyratron circuit. Alternatively, the registering system may comprise a single core, the transfer circuit means coupling the core output winding to its input winding. The circuits described employ bi-stable magnetic cores of material having a rectangular hysteresis loop. In the self-restoring single-core device of Fig. 3, a core 12 may be driven from a normal " 0 " state to a " 1 " state by operating key 17 to apply current through winding 14. If a positive pulse is then applied over lead 18 to fire thyratron trigger tube 19, condenser 20 discharges through winding 13 thus returning the core to " 0 ". The current induced in winding 16 charges condenser 23. When condenser 20 has discharged, conduction in tube 19 ceases; condenser 20 is re-charged through resistor 21 and condenser 23 discharges through resistance 24 and winding 15, thereby restoring the core to the " 1 " state. Fig. 4 shows the output waveforms 1 and 2 at taps 26, 25; the first positivegoing part of waveform 2 may be used as an incoming signal to another device. In a binary counting device (Fig. 5, not shown), a pair of cores are switched alternately in response to triggering pulses. In a decimal counter, Fig. 7, a " 1 " state is stepped around a ring of ten cores, the first core 56 being set in the " 1 " state by key 54 to represent the initial or zero condition. For each trigger pulse on lead 40, condenser 42 discharges through coils 43-52, one for each of ten cores, to drive all the cores to " 0 ". The condenser such as 58 for the core previously in the " 1 " state is thus charged, and subsequently discharges through a resistor and coil, such as 59, 60, for the next core to drive it to the " 1 " state. As the counter is stepped, pulses appear in succession on the 1 to 10 output leads. The counter may be the first order of an accumulator, the carry output on the 10 lead 62 being used as a trigger input for the next higher order counter. The counter ring may be broken for clearing purposes by opening key 65. U.S.A. Specification 2,502,360 is referred to.
