Filed: 1973-07-27
Abstract: 1398860 Impulse transmitters; substation equipment ITT INDUSTRIES Inc 27 July 1973 [3 Aug 1972] 35834/73 Heading H4K In a substation which is connected to line via a rectifier bridge, the speech circuits, an impulse repeating transistor and a power storage capacitor are connected in series across the bridge, and a transistor switch that serves as a dial off-normal contact is connected across the speech circuits. Digits produced by a keyset are stored in an integrated circuit S which is powered from the line charged capacitor C. When ready to "dial" circuit S produces a voltage on its terminal Z that turns-on transistor T8 and thereby turns-on an off-normal transistor pair T7, T9. During the dialling operation, circuit S pulses transistor T2 on and off so as to correspondingly enable the impulsing transistor pair T1, T6. Switch K, which may be a transistor, is actuated with the switch hook HU so as to connect the power source consisting of the capacitor C and Zener diode Z1 to the circuit S. A more rapid build up of charge in the capacitor may be produced by briefly energizing T7, T9 and T8 when the handset is lifted. Unless the bridge rectifier is composed of Zener diodes, it should be shunted by limiting diodes such as ZS and Z2. Transistor T6 of the Darlington impulsing pair may be replaced by a diode. In another arrangement (Fig. 2, not shown), the impulsing transistor (T3) is connected between the bridge rectifier and the speech circuit, and a diode connects the latter circuit to the storage capacitor.

Abstract: 1349108 Sanitary closets; treating sewage THETFORD CORP 3 Aug 1972 [31 Dec 1971] 36397/72 Heading C1C [Also in Division El] A sanitary closet, of the type in which liquid is re-circulated from a tank beneath the closet bowl for flushing the latter, uses liquid in the form of an electrolyte, e.g. sodium chloride solution, and includes first and second chambers which may either be incorporated in the tank, as shown, or be formed as a separate structure, means for circulating the electrolyte such that it passes from the second chamber to the bowl for flushing, from the bowl to the first chamber and, upon reaching a predetermined level in the first chamber, from the first chamber to the second chamber, and a pair of electrodes in each chamber between which current may be caused to pass via the electrolyte such that electrolysis of the sewage in the electrolyte in both chambers occurs. In the preferred embodiment, a plastics bowl 3 has a manually operated pivoted flap 4 normally closing an outlet which delivers to a splash pan 10, also of plastics material, moulded to provide a strainer 11 having slots 12, a macerating impeller 19 driven by an electric motor 17 comminuting the sewage for passage through the slots 12 into first chamber 24. The electrolyte can spill over from chamber 24 over the top of wall 25 into the second chamber which surrounds chamber 24 and extends to one side thereof where the surface of the electrolyte is radiated with ultra-violet light from a bulb 14. One pair of electrodes (27, 28, Fig. 4, not shown) is provided at the ends of chamber 24 and another pair 30, 31 as shown in the second chamber, an ion-permeable barrier 33 being positioned adjacent the negative electrode 31 to prevent the passage of visible particles which would otherwise cause cloudiness in the electrolyte. A pump 40, driven by electric motor 41, circulates the electrolyte via pipe 42 and flushing opening 43. In operation, a timer (Fig. 6, not shown) is set to provide for supply of current to the electrode and light bulb 14 for a predetermined period, e.g. half an hour, at any time during which the circuit may be broken and replaced by a circuit including the motors 17 and 41. This is effected by depressing a switch button on a handle for operating the flap 4, the switch operating a relay. This arrangement is intended to conserve current which is from a 12 volt D.C. supply, e.g. on a vehicle, or from a transformer-rectifier.

Abstract: 1442327 Vehicle supply systems LUCAS ELECTRICAL Ltd 23 July 1973 [4 Aug 1972] 36462/72 Heading H2H A vehicle electrical system comprises an alternator 11, a warning lamp 18, an ignition switch 19, a voltage regulator, a starter motor 41 and a control circuit which when energized enables the starter motor to be energized, the control circuit being de-energized when the alternator produces an output. When the ignition switch 19 is closed, the warning lamp 18 and an oil pressure warning lamp 52 connected to an oil pressure switch 53 are energized. The lamp 18 is extinguished when the alternator produces an output on line 17 and when the battery voltage reaches a predetermined value a Zener diode 24 in the voltage regulator conducts to switch on a transistor 25 thereby switching off transistors 27, 28 to cut off the current supply to the alternator field winding 29. The engagement of the switch 19 with a contact 21 enables energization of a relay 36 via conductive transistors 43, 44 thereby closing contact 37 and energizing a relay 38, the closed contact 39 of which allows the starter motor 41 to be energized. When the alternator produces an output the equality of the voltage on the line 17 and the battery voltage causes the transistors 43, 44 to be turned off thus preventing energization of the starter motor. The opening of the switch 53 when the engine is running also prevents energization of the starter motor.
