Title: Glass passivated high power semiconductor devices
Inventor: OSTOP JOHN ANTHONY
IPC: H01L29/06
Filed: 1982-06-30
Abstract: A process for producing a glass passivated semiconductor device, such as a thyristor, comprises forming a first groove 56 in a large area body of semiconductor material, forming regions 62,64,66, of alternating type conductivity within the area enclosed by the groove and then forming a second shallower groove within the area enclosed by the first groove, the second groove then being coated with glass 84 to passivate the surfaces exposed by the second groove. Electrodes 90,96 are then affixed to preselected regions to form a semiconductor device. A plurality of such devices may be made in a single semiconductor body and separated by cutting through the body outside the first groove. <IMAGE>

Title: Gas liquid contact apparatus
Inventor: NUTTER DALE EDWARD
IPC: B01D3/16
Filed: 1982-07-10
Abstract: Vapour-liquid contact apparatus, includes a plurality of grids which are arranged in a vertical stack. Each grid is formed of a plurality of parallel, horizontal elongated segments (4) orthogonal to those in the grid therebeneath. Each segment has an upstanding flange (4) which supports a downflowing film of liquid, and a trough portion (10) for receiving liquid which has flowed from the flange. The trough portion is provided with liquid drain openings (14) located to release liquid directly onto contacting upper edges of the flanges (4) of the next lower grid. The gas flows upwardly through openings provided between the flanges and troughs of the segments; ascending gas strikes the lower surface of the trough giving the gas a slight angular velocity without a substantial pressure drop, promoting the contact of the gas with the liquid film on the flange. <IMAGE>

Title: Circuit arrangement for coupling and demagnetizing of electromagnets fed by direct current
Inventor: KARJALAINEN VAINO
IPC: H01F7/18
Filed: 1982-08-16
Abstract: A circuit arrangement for enabling the magnetization and demagnetization of electromagnets operated by direct current utilising the self induction current produced in the coil of the electromagnet has two polarized capacitors (C1, C2) connected in parallel with the coil (L) of an electromagnet (M), the capacitors being series connected such that their like poles are connected to each other and a reverse direction diode (D1, D2) is connected in parallel with each capacitor (C1, C2). The magnetizing voltage charges one of the capacitors (C1) through diode (D1) so that it will not be damaged by the self induction voltage produced in the coil (L) of the electromagnet (M) after the magnetizing current has been cut off, the voltage being opposite to the polarity of the capacitor (C1). The electrical energy produced by self induction in the coil (L) of the electromagnet (M) after the magnetizing current has been cut off will become charged and levelled out into the capacitors (C1, C2), producing a low resistance to the self-induction voltage and thus causing strong demagnetizing current in the coil (L) of the electromagnet (M). In alternative circuits only one diode is used (Figs. 2, 3, not shown), and one or both of the capacitors may be a non-polarised capacitor. <IMAGE>

Patent GB-2132047-A (GB)
Title: Frequency divider circuits
Inventor: CHIVERS HOWARD ROBERT
IPC: H03K23/66
Filed: 1982-12-04
Abstract: A frequency divider circuit allows a desired long-term output frequency (with acceptable short-term deviations) to be generated from a master crystal oscillating at a higher frequency. A digital monostable divider unit D1 is connected in cascade with another such unit D2 and is supplied with a stable oscillator-controlled frequency input at I. The unit D1 has a period of N cycles, providing the major frequency division component, and the unit D2 provides the desired lower output frequency at O and is controllable for alternative switching after 1 or 3 cycles instead of the normal 2, the sum of the periods (N+2) representing the basic division ratio of the circuit. The output O is connected to the input i of a digital M counter which resets automatically after a count of M, when an output "modify" signal from an output o of the counter is applied at m to the divider unit D2. This signal renders operative a control signal applied to a fast/slow control signal input c1 of the unit D2 so that this unit switches after 1 or 3 cycles, instead of the basic 2, according to the value of the control signal. The M counter is programmable by a programme control signal at c2, so that the value of M can be varied to vary the long-term output frequency. <IMAGE>

Patent GB-2131377-A (GB)
Title: Apparatus and method for replacing conveyor belts
Inventor: HOLLIS KENNETH G
IPC: B65G15/00
Filed: 1983-11-17
Abstract: For replacing a worn conveyor belt (10) a take-up end of the belt is taken-up by a take-up mechanism (14) and a pay-out end of the belt is payed-out by a pay-out mechanism (16). In so doing, the belt (10) imposes a take-up resistance tending to resist the taking-up of the take-up end and a draw-out force acts to draw-out the replacement end. A force-transmitting mechanism interconnects a take-up tensioner (18) and the pay-out tensioner (20) for transmitting the take-up resistance and the pay-out force into counteracting relationship. At least a substantial portion of the take-up resistance and pay-out force is thus cancelled-out, thereby greatly reducing the power requirements of the take-up mechanism. <IMAGE>

Patent GB-2132017-A (GB)
Title: Semiconductor device array
Inventor: WILLIAMS GERALD MARTIN
IPC: H01L29/221
Filed: 1983-12-12
Abstract: A semiconductor device array comprises a substrate 10 on which a single crystal semiconductor layer (13, Figure 2) may be grown, an intermediate material layer 11 on the substrate 10 defining individual island regions 12 of the substrate 10 for device formation, and a semiconductor layer (13, Figure 2) upon the intermediate layer 11 and island substrate regions 12. The substrate 10, intermediate layer 11 and semiconductor layer (13, Figure 2) are chosen such that the semiconductor layer (13, Figure 2) is polycrystalline on the intermediate layer 11 but single crystal upon the island substrate regions 12. Since polycrystalline material generally has lower conductivity than single crystal material, this construction provides a device array with inter- device electrical isolation. The substrate 10 may be InSb, the intermediate layer 11 polycrystalline ZnS and the semiconductor layer (13, Figure 2) CdTe or CdxHg1-xTe. The device may form an array of infra-red detecting diodes. <IMAGE>

Patent GB-2142498-A (GB)
Title: Earth horizon sensor
Inventor: SODEIKAT DIETER
IPC: G01S3/786
Filed: 1984-05-15
Abstract: An earth horizon sensor 1a for a geostationary satellite has a chopper disc 3a (e.g. a disc with the apparent diameter of the earth) in the image plane of optical system 2a and which oscillates at a constant frequency so as to allow light from opposite earth horizons to fall on a single infra-red detector 9a. If the two earth horizons emit different amounts of infra-red radiation, an anomaly constituent is contained in the detector output signal. This can be determined by utilizing signals corresponding to different amplitudes of oscillation of chopper disc 3a. Since the anomaly-dependent component in the detector output signal depends on this chopper amplitude, the correction for the anomaly component can be determined. <IMAGE>

Title: Measurement of chamber volume
Inventor: FISHER HARRY W
IPC: G01F25/00
Filed: 1984-07-24
Abstract: The invention relates to a method and apparatus for measuring the volume of a chamber, for example a variable volume chamber 12 of regular geometry defined by a movable element, particularly the chamber of a meter prover. Electromagnetic waves are generated in the chamber, the frequency is varied to establish a resonant wave standing condition in the chamber; the mode of generation being selected so that at said resonant condition, the electric and magnetic components of the field generated are related to the dimensions of the chamber. By determining the capacity of the chamber at first and second positions of the piston or other movable element a displacement volume is determined with great accuracy and this is compared with the high resolution signal to determine the incremental volume of fluid displaced by incremental measured movement of said element, e.g. relative to a single pulse of the train. <IMAGE>
