Abstract: 1,197,969. Voltage variable PN junction capacitor. SIEMENS A.G. 19 Dec., 1967 [22 Dec., 1966], No. 57493/67. Heading H1K. A voltage variable capacitor consists of a semi-conductor body with a plurality of mesas on one face each containing a single PN junction, all of the junctions being connected in parallel between the electrodes. Such an arrangement exhibits a much greater capacitance variation than a device with a single mesa of the same total junction area and the same inclination of its sides to the junction. In the preferred form a high resistivity N-type layer is formed epitaxially on one face of a P + layer which is then etched to form the mesas. The isolated N zones are then interconnected by soldering or thermocompression bonding them to a common foil or by means of a layer of metal deposited over an oxide coating provided with an aperture over each mesa. The N-type layer may alternatively be formed by diffusion.

Patent GB-625504-A (GB)
IPC: B60R16/02
Abstract: 625,504. Supply systems for discharge lamps. BUNN, E. W., and WRIGHT, W. J. Aug. 1, 1947, No. 21060. [Class 38 (iv)] Electric-discharge lamps for vehicle lighting are supplied from a low-voltage battery through voltage augmenting means such as rotary transformers. One such transformer is arranged to sup-, ply two lamps in series and an additional transformer is introduced by switching means in starting each pair of lamps, such switching means also introducing means to produce a starting surge of voltage, such as by a tapped choke through which flows the charging current of a condenser. The system shown comprises two rotary transformers RT1, RT2, each driven from a battery or other low-tension source. The circuits are arranged so that in the first position of ganged switches SW1 ... SW3, lamps T1, T2 in series are connected through both transformers, a ballast and voltageadjusting resistance VR1 and a step-up autotransformer winding CH to receive a starting surge due to the current which charges a condenser G as the switches are closed. In the second position of these switches the lamps T1, T2 are across the transformer RT1 through a ballast and voltage-adjusting resistance VR3 and switch SW2 prepares a circuit for operating the lamps T3, T4. To start the latter lamps, ganged switches SW4, SW5 are placed in their first position and a retractive switch SSW momentarily closed, whereby a surge due to condenser G is induced by winding CH in a circuit, including the lamps and both transformers RT1, RT2 with resistance VR2. In the second position of switches SW4, SW5 the lamps T3, T4 are run across transformers RT2 with resistance VR4 in series. Reversing switches PSW are supplied to reduce end blackening due to the D.C. lamp current. Each additional pair of lamps would be supplied from an additional rotary transformer, the switches causing one other transformer to supply the extra starting voltage.

Filed: 1969-12-31
Abstract: 1,234,915. Radio signalling. MOTOROLA Inc. 31 Dec., 1969 [10 Jan., 1969], No. 63447/69. Heading H4L. A radio transmitting and receiving apparatus uses common encoder-decoder equipment including a continuously operating oscillator for responding to or transmitting a calling tone. The encoder-decoder comprises a filter 18 coupled to the output of the receiver discriminator 16 for selecting the tone signal, the output of the filter being supplied via an amplifier 72 to a reed filter 32 which is resonant at the tone frequency. The output of the reed filter is supplied via an amplifier 36, feedback amplifier 41 and amplitude limiter 19 to the input of the amplifier 72 to form a tone signal oscillator which is coupled via potentiometer 45 to the modulator 11 of the transmitter to transmit the calling tone when the apparatus is switched to transmit. On reception, the received tone signals are of much greater amplitude than those supplied from the limiter 19, producing a much greater output from the reed filter 32 and causing a normally cut-off detector 58 to conduct and discharge a capacitor 62, whereby a transissistor 59 is cut off. This removes muting from the receiver amplifier 17 so that the output of the discriminator is coupled to the audio output circuits. Removing the microphone from the hang-up box 61 or operating a switch 60 also renders the amplifier 17 operative.
Patent GB-686894-A (GB)
Abstract: 686,894. Control of D.C. motors. BOSCH GES., R. May 28, 1951 [May 30, 1950], No. 12404/51. Class 38 (iii) [Also in Group XXXV] A two-stroke internal combustion engine is started by a reversible motor 14-16 of insufficient power to turn the engine over dead-centre. Operation of a starting handle 12 engages the starter pinion 11 with an engine wheel 13 and closes a switch 36, 37, whereby a battery 26 energises a starting contactor 18 over the contacts 33, 35 of a reversing switch 34. The motor then starts up (under the action of field 15) and turns the engine in a direction opposite to that in which it normally runs until the engine compression eventually causes the motor to stall. In the meantime a stepping magnet 38 of the reversing switch has been energized by closure of contacts 39, 42 of a relay 20 having opposing coils 40, 41 energized, respectively, by the voltages across the armature and field of the motor. When the motor stalls, the relay releases, magnet coil 38 is de-energized and the contact 35 of the reversing switch moves into engagement with contact 32. Ignition coil 70 is thereby energized, as also is contactor 17 which re-starts the motor in the reverse direction (under the action of field 14). The compression previously built up assists the motor in turning the engine over dead-centre, so that the engine should now become self-running. In modified arrangements the armature of the coil 38 operates contacts controlling the connection of the relay coils 40, 41 to the motor; or these coils may act directly on the armature of coil 38.
