Title: Cadmium Mercury Telluride Deposition
IPC: C01B19/00
Filed: 1981-05-18
Abstract: A layer (20) of CdxHg1-xTe is grown on the surface of a substrate (21) by decomposing volatile compounds of cadmium and tellurium e.g. alkyls in a mercury atmosphere. The substrate (21) is placed in a vessel (16) containing a mercury bath (19) with the vessel and bath at a suitable pressure and a temperature below the alkyl decomposition temperature. Hydrogen is passed through bubblers (6, 7, 25) separately containing alkyls of cadmium, tellurium, and if required a dopant, into the vessel (16). The substrate (21) is independently heated (18) above the temperature of the vessel (16) so that the alkyls decompose on the substrate (21). The substrate may be CdTe, a II-VI compound or mixed II- VI alloy. The alkyls may be dimethyl cadmium, diethyl cadmium, dipropyl cadmium, dimethyl telluride, diethyl telluride, dipropyl telluride or dibutyl telluride, or hydrogen substituted tellurium alkyls such as hydrogen ethyl telluride. <IMAGE>

Title: Extracting energy from a body of flowing water
Inventor: MACGREGOR DANIEL
IPC: F03B17/06
Filed: 1981-07-25
Abstract: A floating structure comprises an inlet passage of reducing cross-section in the direction of flow communicating at its downstream end with a pair of channels (5a, 5b), Figure I (not shown), alternately opened and closed to the flow from the inlet passage via a pair of moving guides (3a, 3b) located at the sides of the passage. Each channel has a pair of rotary paddles 9a, 10a, Figure III, so arranged that they are in the positions shown when the inlet flow is communicated to the associated channel, whereby the water flows past the paddle 9a, impinges on the paddle 10a and thus moves up into chamber 11a to compress air therein and force it through a valve 12a into a reservoir. The paddles continue to rotate and the guides move so that the inlet flow is directed into the other channel to similarly compress air therein. <IMAGE>

Title: Integrated circuit infra-red detector array
Inventor: KANSY ROBERT J
IPC: H04N5/378
Filed: 1982-12-23
Abstract: Charge accumulated by a given detector in an infrared detector array during one dwell time is read out at the end of the dwell time and added to the charge accumulated by an adjacent detector during the preceding dwell time. In fig.1 the output signals (i.e. accumulated charges) from a column of detectors are read out by sequentially applying positive pulses from a multiplexer (not shown) to the gates 6 of sampling transistors 10, which turn the transistors 10 on to store the detector outputs in capacitors 12. Then pulses from the multiplexer are sequentially applied to gates 7 of transistor 11 to transfer the charges of capacitors 12 to "phase one" capacitors 15. The detector signals of capacitors 12 are added to reference voltages left when the previous cycle was completed. Then the summed outputs in capacitors 15 are sequentially shifted by pulses supplied to transistors 17. "Phase two" then begins, in which the charge of capacitors 15 are sequentially shifted to "phase two" capacitors 16 by pulses supplied to transistors 18. The process is then repeated until the right most "phase two" capacitor 16 contains a summation of all the dwell time samples. Finally, the transistor 19 is turned on by a positive pulse from the multiplexer to pass the summation of all the dwell time samples to a video signal processor (not shown) for processing.
Patent GB-2116432-A (GB)
Title: Improved method and apparatus for manufacturing an artificial limb
Inventor: THOMPSON HERBERT
IPC: A61F2/76
Filed: 1983-02-28
Abstract: In a method of making an artificial limb, a positive impression of an amputated limb stump is produced by first surrounding the stump with a hollow flexible jacket containing polystyrene beads in an inner compartment, inflating an outer compartment if necessary to compress the jacket against the stump, and evacuating the inner compartment so that the beads form a rigid mass moulded to the shape of the stump. The jacket is removed from the stump with the negative pressure in the inner compartment maintained, and is used as a mould for casting a positive plaster impression of the stump which may be used for vacuum forming a definitive thermoplastics socket. The evacuated jacket, whilst still fitted to the stump, can be used as a temporary artificial limb socket for alignment purposes. This is achieved by coupling a temporary distal artificial limb portion including an alignment device to a proximal end portion of the jacket, for example with a casting brim fastened to the jacket, to form a complete temporary limb for performing a dynamic trial. This enables the prosthetist to establish alignment settings which are preserved during the casting of the positive impression, and are automatically transferred to the definitive artificial limb.

Title: Improvements in or relating to ultrasonic array systems
Inventor: GREEN IAN MACDONALD
IPC: G01S7/52
Filed: 1983-03-02
Abstract: An ultrasonic array system comprises a linear array 3 of elements disposed adjacent to a piezoelectric layer 5, each element being connected to a transmitting or receiving channel 4. Circuit 6 selects the channels individually in sequence and passes an output signal from the selected channel, together with a reference signal, to a circuit 7, wherein a correction signal is generated and passed to microcontroller 8, which feeds calibration corrections to the selected channel to adjust certain parameters thereof. In a receiving mode, calibration timing board 9 causes a substantially uniform ultrasonic field to be received by all the elements, via piezoelectric layer 5 and amplifier Tx. In a transmitting mode, a calibration transmitting signal is transmitted through each channel 4 and subsequently from each element of array 3. <IMAGE>
