Title: Semiconductor Devices
IPC: H01L29/00
Filed: 1968-03-12
Abstract: 1,152,156. Semi-conductor devices. RADIO CORPORATION OF AMERICA. 12 March, 1968 [22 March, 1967], No. 12002/68. Heading H1K. The reverse breakdown characteristic of a PN junction formed near the surface of a monocrystalline semi-conductor is improved by the provision on the surface zone of a layer of polycrystalline semi-conductor. Contacts are applied to the monocrystalline bulk and to the polycrystalline layer; the layer may be formed of the same or a different semi-conductor. The diodes 11 shown are held together by glass 12 during processing and when completed may be separated individually or in groups. (The formation of the assembly involves hot-pressing together a glass plate and a prepared semi-conductor structure.) Each diode has a low resistivity mono- or polycrystalline portion 13 carrying a monocrystalline body 14 of higher resistivity; a high resistivity epitaxial layer 16 is deposited on this and then, by more rapid deposition or by the use of a different temperature, low resistivity polycrystalline material 18 is deposited. The first three parts 13, 14, 16 may be silicon and the polycrystalline layer 18 germanium or vice versa or all parts may be silicon. Semi-conductors such as silicon-germanium alloys and A<SP>III</SP>B<SP>V</SP> compounds may also be used. A deathium impurity such as gold may be incorporated in the first portion 13. A transistor (Figure 2, not shown) may be formed as a standard planer transistor and polycrystalline semi-conductor regions are formed instead of the normal electrode metallization for the emitter and base regions. Emitter and base electrodes are then applied to the polycrystalline regions. The material of the polycrystalline regions each may be the same or different to that of the transistor body.

Abstract: 956,037. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. April 4, 1961 [April 4, 1960], No. 12069/61. Heading H4K. In a network comprising a main exchange KC and sub-exchanges EC1, EC2, UC, all calls from the sub-exchanges are directed in the first instance to a register at the main exchange which receives the dialled digits and, if the call is within the network, sends them back in VF form to a discriminator at the originating exchange, the connection to the main exchange being released if and when it is found not to be required. On a call from UC to EC2, for example, a connection is made via EC1 to KC, and the discriminator at UC determines the destination of the call in response to signals from KC. The connection is then set up either directly to EC2, or via EC1, or, if both these routes are unavailable, via EC1 and KC. A call outside the network is established under the control of the register at the main exchange. The connections at each exchange are preferably established by cross-bar switches operating under the control of markers. The circuits of the sub-exchanges are described with reference to Figs. 4a . . . 4c, 5a . . . 5c (not shown).

Filed: 1921-04-29
Abstract: 178,729. Evans, W. E., (Allgemeine Elektricitõts-Ges.). April 29, 1921. Fuel, feeding.-Pulverulent fuel is fed to furnaces bv a screw feeder b which forces the fuel through a thin annular space g between the cone d, rotating with the screw, and the nozzle-casing. The annular stream of fuel so formed meets a current of compressed air from the pipe f, causing an intimate mixing of the air and fuel before entry into the furnace nozzle l. A hand-wheel h, operating the cone d, regulates the supply of fuel, while the air is separately controlled bv the valve e. In a modification the cone d and the screw b are mounted on separate shafts and may be rotated at different speeds.

Title: Improvements in or relating to an Electronic Speed Regulator for Electric Motors
IPC: H02P7/291
Filed: 1967-03-17
Abstract: 1,175,096. Automatic control of speed. PAILLARD S.A. March 17, 1967 [April 4, 1966], No. 12532/67. Heading G3R. [Also in Division H3] The speed of a motor M is controlled by regulating the on/off periods of an electronic switch (a transistor 1) in response to the amplified difference in duration of pulses generated by a motor driven device e and that of reference pulses. As shown, the reference pulses are generated by a monostable multi-vibrator 8, 9 triggered by the output 6 of a Schmitt trigger 4, 5 which squares the pulses from generator e. The output 6 is also applied to the base of a transistor 12, the emitter of which is connected at 11 to the multivibrator so that 12 conducts only when a pulse is present at 6 and absent at 11, i.e. for a time equal to the difference in duration of the respective pulses. This difference is amplified by the circuit comprising capacitor 17; this is charged during the conduction of 12 (and 15, 16) and discharged through 19 for the remainder of the time, and a transistor 21 is conductive whenever the charge is above a low level. 21 is connected to amplifier stages 22, 23, 24 to directly control the conduction of transistor 1. Desired speed is adjusted by varying the time constant of the multi-vibrator 8, 9. Circuit 27, 29, 30 ensures conduction of 1 at starting, when pulses from e are absent. A further monostable multi-vibrator 33, 34 positively switches the first back to its stable state at the end of each pulse from the Schmitt trigger to prevent the motor being controlled at a multiple of the desired speed. The motor may drive a cine camera, and it is stated that the action of the multi-vibrator 8, 9 could be controlled by a separate signal source, e.g. to synchronize sound and vision.

[Class 118 (ii)] A lamp-failureindicating device comprises a perforated metal diaphragm, placed in the hot gases and controlling a pivoted contact arm, and a perforated plate mounted adjacent the diaphragm, between it and the contact arm, to shield the diaphragm from down draughts of cold air. A downwardly depending hollow metal cone may be rigidly attached to the diaphragm to concentrate the ascending hot gas. As shown in the drawing the perforated diaphragm 3 carrying the metal cone 7, is mounted in the lamp by supports 19, and is protected against cold downdraughts by an exactly similar metal plate 6, the diaphragm and plate both being dished and separated slightly at the centre as indicated. A contact lever 10 biassed by a spring and an arcuate weight 12 is pivotally mounted above the plate at 8 and passes down through holes in the plate and diaphragm to terminate in the contact member 11. As shown the contacts 11 and 16 are normally apart, the distance being adjustable by screw 17, but when the diaphragm expands due to the hot gas the contacts 11, 16 close to complete an indicating or alarm circuit. Alternatively expansion of the diaphragm may open a normally closed alarm circuit. Specification 166,734, [Class 118 (ii)], is referred to.
