Title: Improvements in Electric Ignition Systems for Internal Combustion Engines.
Filed: 1919-01-02
Abstract: 122,184. Dayton Engineering Laboratories Co., (Assignees of Hunt, J. H.). Jan. 2,1918, [Convention date]. Interrupters, mechanical.-Ignition is prevented on the accidental reversal of the engine by the employment, in addition to the main interrupters 65, 66, of an interrupter 67 having a resistance 84 in circuit. During normal running, the auxiliary interrupter opens prior to the opening of the main interrupters which register with the engagement of the distributor arm with its fixed contacts. On reversal, however, the main interrupters open first, and on account of the resistance 84 the current across the contacts 72, 75 is so small that an impulse of sparking strength is not produced. The interrupter contacts are supported on a bracket which may be rotated for the purpose of causing the main interrupter contacts to break simultaneously. Current is introduced by the spring which, secured to the casing at one end, encircles the pivot of the lever, and bears against it in the neighbourhood of the contacts, a cushion to prevent chattering being interposed. The other ignition and engine arrangements are identical with those deseribed in Specifications 121,739 and 122,185.

Title: Improvements in or relating to electrical code translators
Inventor: FREEDMAN ARYE LEIB
IPC: H04Q3/42
Filed: 1958-01-02
Abstract: 904,503. Automatic - exchange systems. ERICSSON TELEPHONES Ltd. Dec. 23, 1958 [Jan. 2, 1958], No. 233/58. Class 40 (4). In a translator in which a wire representing the number to be translated is threaded through one core in each of a group of cores, each group is enabled in turn whereby the digits of the translation are emitted in succession. As shown, Fig. 1, each group of cores is provided with a control wire K1 . . . K4, energized when its associated flip-flop is in its normal state which occurs when it is fed by a train of pulses Q. When a control wire is energized it saturates each of its group of cores with magnetization of the same sense as would be produced by current through one of the threaded windings such as A, and consequently such a core produces no output on its winding U when a lead such as A is pulsed. However, between pairs of Q pulses the flip-flops F1 ... F4 are successively changed over to their second states by pulses P1 . . . P4 so that control leads K1 K4 are de-energized so that pulses on lead A are in turn transmitted to the output windings of cores 2, 4, 1, 6 in the respective groups. Instead the control wire may, when energized, drive the core well into saturation and the wires A may be provided with A.C. which is introduced into the output winding of a core whose control winding is not energized at the time. In an alternative embodiment, Fig. 2, bistable saturable cores are provided, the control lead K1 . . . K4 being provided successively from gates G1 . . . G4 with half-set pulses. The threaded wires such as A are provided also with half-set pulses, so that each core, where these coincide, is fully set and produces an output on its winding U. The latter may be provided with a rectifier so that an output is provided either only on the setting or only on the resetting of the core which is effected immediately afterwards by a common pulsed reset winding. Alternatively the reset winding may be provided with continuous current, the core requiring the combined effects of current in a control winding and in an input winding such as A in order to overcome the reset current to a sufficient extent to set the core. In a further modification the reset lead is dispensed with, current from wire A being arranged to set one core in each group and the control wires are then pulsed in succession to restore the cores. Rectifiers in the core output leads ensure that an output is only obtained on the reset action.

Title: Improvements in or relating to electrical monitoring circuits
Inventor: WREN JAMES FRANK
IPC: G08B23/00
Filed: 1967-01-03
Abstract: 1,137,811. Monitoring circuits. TELEPHONE MFG. CO. Ltd. 3 Jan., 1967, No. 247/67. Heading G4N. [Also in Divisions G1 and H3] In monitoring apparatus for detecting the departure of an electrical quantity from a nominal value, a D.C. signal representative of the value of the quantity is compared with a D.C. reference potential corresponding to said nominal value and having superimposed thereon a square wave reference signal. The apparatus includes a differential amplifier TR1, TR2 to one side B of which is applied the D.C. reference potential, derived from Zener diode ZD1, and the square wave applied from C through capacitor C4, and to the other side A is applied to the D.C. input signal, derived by rectifying and smoothing at D1, C1 a signal applied at G, H. The output of TR1, TR2 is passed through a differential amplifier TR3, TR4 to a transistor switch TR5. When signal A has its nominal value, TR5 is biased to its threshold so that the square wave causes it to be switched on and off alternately, the output square wave from TR5 being amplified in TR6, TR7, rectified and smoothed at D4, C6 and thus energizing relay RL. Should the D.C. input signal at A depart either up or down from its nominal value to the extent that TR5 is either permanently cut-off or permanently saturated (i.e. depart by an amount greater than half the peak to peak amplitude of the square wave at B) then TR5 provides a D.C. output which is blocked by capacitor C5, and relay RL becomes de-energized. Amplifier TR1, TR2 is balanced by adjustment of resistor R13; the amplitude of the square wave at B, and hence the latitude of the D.C. input signal, is adjusted by resistor R9; and the bias of TR5 is adjusted to the threshold by resistor R16. D2 compensates for the temperature coefficient of D1. The circuit may be used to monitor quantities representative of, e.g. temperature, pressure or resistance.

Abstract: 156,478. Nitrogen Products Co., (Assignees of Hidden, C. P.). Jan. 27, 1919, [Convention date]. Gaseous-fuel furnaces.-In a furnace for "fixing" nitrogen by conversion into sodium cyanide, the solid material to be treated (namely, briquettes of sodium carbonate, and finely divided carbon and iron) pass downwardly by gravity through an annular retort heated externally in a furnace setting and internally by gaseous fuel and air supplied by concentric pipes 27, 34 respectively to the central chamber of the retort. A supply of heated nitrogen reaches the fused material as it leaves the zone of highest temperature. Part of the nitrogen is supplied upwardly to cool the finished product and mixes with the remainder which issues at a high temperature from a pipe 39 carried downwardly through the central heating chamber. The central chamber has a closed or thimble-like inner end which is protected by refractory material moulded in a plastic state to the shape shown. The upper part of the retort comprises a hopper-like mouth into which the briquettes are fed and which constitutes a preheating zone. Both inner and outer portions of the hopper portion are readily removable and are spaced apart by radial aligned ribs 16<1>, 25. The inner member of the retort hangs by a ring 18 from the inner member of the hopper. The retort itself is readily removable from the setting and makes joint therewith by packing powder 13 and rings 13<1>.

Abstract: 676,808. Two-way transmission; loudspeaker systems. SOC. D'ETUDES DES PROBLEMES. DE COURANTS FAIBLES S.E.P.C.O. Jan. 6, 1950 [April 25, 1949], No. 394/50. Class 40 (iv). In a two-way loud-speaker communication system each station has a microphone amplifier and an auxiliary control amplifier connected in parallel, the auxiliary amplifier controlling a relay for disconnecting the cathodes of a further auxiliary amplifier effective in the reverse direction and for connecting the cathodes of the microphone amplifier to earth. The cathodes of the line amplifiers 24, 25 and 33, 33a are normally disconnected at the contacts of relays R2 and R1, respectively, which relays are controlled when speech occurs simultaneously at both ends by the difference in the potentials produced across resistors 49, 55 in the case of R1 and resistors 60, 61 in the case of R2, resulting from the difference in inputs to the control amplifiers 38, 39 and 23, 29. The actuation of either relay renders the appropriate line amplifier active and the control amplifier for the opposite direction ineffective. Manual control of the effective direction is included in a modification described with reference to Fig. 4 (not shown). The system is described as applicable to a conventional intercommunication system and to a system in which a single instrument is used both as a microphone and a loudspeaker.
