Patent GB-2202236-A (GB)
Title: Manufacture of electronic devices comprising cadmium mercury telluride involving vapour phase deposition
Inventor: BURNS GORDON PETER
IPC: C23C16/30
Filed: 1987-03-09
Abstract: In the manufacture of an electronic device, for example an infrared detector, from a crystalline layer (11) of cadmium mercury telluride, as illustrated in Figs. 4 & 5, a surface (9') of a substrate (10) is irradiated to apply a heat pulse (20) which removes surface material (8) so as to leave a clean surface (9) suitable for the growth of the crystalline layer (11). During the application of the heat pulse (20) and the deposition of the layer material (11), the substrate (10) is maintained in a non-oxidising ambient, for example a stream (5) of hydrogen, nitrogen or a noble gas. This gas (5) may carry Hg vapour to the substrate (10'), and volatile Cd and Te compounds may be introduced into the gas stream during the deposition. Although at least most of the material for the cadmium mercury telluride layer is deposited below 550 DEG C (and preferably below 450 DEG C), the substrate surface (9') may be heated rapidly by the pulse (20) to a temperature in excess of 800 DEG C (even in excess of 1000 DEG C) to permit the removal of silicon dioxide surface layers (8) from silicon substrates (10). Due to its short duration, the pulse (20) can effect the cleaning without degrading the quality of the deposited layer (11) or degrading circuit elements (55) in the substrate (10). In a modification a buffer layer (12) of CdTe may be grown on the clean surface (9) before the cadmium mercury telluride layer (11), after which the cadmium mercury telluride layer (11) may be grown on this CdTe buffer layer (12) by liquid phase epitaxy. The heat pulse may be produced by switching a radiant heat source directed at the surface of the substrate or by directing a pulsed laser. The substrate treated may be monocrystalline silicon or monocrystalline germanium. Electronic devices manufactured may be photoconductive infrared detectors, photodiode infrared detectors and bipolar transistors. <IMAGE>

Title: Low fat spread and process for producing same
Inventor: BRINKERS BERNARDUS HUBERTUS CO
IPC: A23D7/015
Filed: 1987-06-19
Abstract: A low fat spread comprising an emulsifying agent and protein comprises gelatin and unmodified or modified starch in the disperse waterphase. The gelatin used is preferably gelatin capable of forming a 3 wt%'s gel in water having a melting range of 20-30 DEG C; the preferred starch is physically modified starch. The process for producing such low fat spread is essentially a process in which the waterphase is prepared in a one vessel operation whereby all ingredients are added while maintaining the pH at a value from 5.5-6.0.

Title: Method and apparatus for making an electrical contact
Inventor: ANDERSEN STEPHEN VERNER
IPC: H01R43/16
Filed: 1987-07-08
Abstract: An apparatus for controllably shearing a thin workpiece (W) of electrically conductive material to make electrical contacts having specially configured spaced apart tongues (75, 77) arranged to mate with plug connectors of standard design. The apparatus rigidly supports the flat faces (14, 16) of the workpiece (W) except in the precise area (46a, b, c) at which the tongues (75, 77) are to be formed. Thus, during the shearing step the material to form the two tongues (75, 77) is separated by shearing and the material for each tongue (75, or 77) is also separated from adjacent, rigidly supported regions of the workpiece (W) by shearing. This double shear control the shearing step to ensure that the tongues (75, 77) are correctly formed. The y-section portion thus formed is blanked from the surrounding material and the tongues 75, 77 are formed to final shape (Fig. 8). <IMAGE>

Title: Gain control circuit
Inventor: SELF DOUGLAS
IPC: H03G1/04
Filed: 1988-01-06
Abstract: A gain control circuit PL has positive feedback means A1, R1 coupled to the output of the circuit PL so as to increase the gain of the circuit PL. The positive feedback provided by A1, R1 compensates for the wiper resistance of the potentiometer PL. Described is a sound control circuit having substantially identical circuits for both the left and right channels. The signal is fed in each channel through a respective potentiometer (PL, PR) for varying the gain of each channel. The output of each potentiometer (PL, PR) is fed back by way of a positive feedback circuit (A1, R1 : A2, R2) incorporating a buffer amplifier (A1; A2) configured to have a small gain. The positive feedback increases the off-ratio of the circuit and optimises the control law. <IMAGE>

The invention comprises diphenyl ether derivatives of the general formula where R 1  is a methoxy or acetylamino group, R 2  and R 3  each represent a hydrogen; or iodine atom or a methyl or acetylamino group and R 4  represents a chlorine, bromine or iodine atom. The compounds may be prepared by reacting in the presence of a tertiary organic base, e.g. pyridine, a 5-nitro-4-hydroxy benzaldehyde halogenated in the 3 position with an aliphatic or aromatic sulphonic acid halide and reacting this intermediate product, without isolation, with a phenol of the formula at an elevated temperature, e.g. at reflux. The first reaction preferably takes place at room temperature using benzene sulphonyl chloride which is added to a suspension of the aldehyde in the tertiary base so that the temperature does not exceed 40‹C. The second step preferably takes place below 130‹C., the tertiary base then removed and the residue taken up in a neutral organic solvent for further purification.

Title: Coin checking apparatus
Inventor: DRINKWATER RAYMOND JOHN
IPC: G07F1/04
Filed: 1989-06-23
Abstract: Coin checking apparatus has a coin fall path, a timer 21 which is enabled in response to passage of the coin past a first point 31 in said path and disabled in response to passage of the coin past a second point 22 in said path. A validation signal is generated in response to a predetermined count of said timer when disabled. An alarm may be sounded if a different count is achieved. The apparatus may be used in conjunction with conventional coin validating unit 12 and is useful to sense a coin fall which is slower than a free fall, due to the attachment of an extracting cord to the coin. The timer 21 is an inductive oscillator operating at low frequency, passage of a coin affecting the inductance of the oscillator and its operating frequency. A counting circuit (23, Fig.2) counts the beats of the oscillator and compares it with a reference frequency. The passage 26 between the validating unit 12 and the storage channels 14, 15 may be provided with a shutter to prevent a coin on a thread being pulled out again, or with a guillotine to cut any thread present. <IMAGE>

Title: Golf bags
Inventor: QUELLAIS JACQUES
IPC: A63B55/00
Filed: 1990-03-26
Abstract: A golf bag is provided with a strap (2) to be carried over the carrier's shoulder. The strap (2) is connected to the bag at a top point (3) and a lower point (4). The position of the lower point (4) can be adjusted longitudinally with respect to the bag and the strap (2) is also connected to the bag at an intermediate point (7) with respect to which it can slide (8). Sliding at this point (7) makes it possible to adjust the working length of the strap (2) to suit the carrier and the corresponding displacement of the lower point (4) makes it possible to tauten the unused portion of the strap (2) and hold it against the bag. This device avoids the formation of undesirable loops or lugs in the unused portion of the strap (2). <IMAGE>

Title: Database correction and conversion.
Inventor: BIDDLE MARTIN
IPC: G06F17/27
Filed: 1992-02-04
Abstract: A process 1 is disclosed for conversion of an input database to an output database having an improved data structure and corrected data words. A set of lexicons is stored, 2, for each field of the input database. For each word position in a particular field, a search priority order is set, 3, for the associated lexicons based on the probability of the lexicon containing a word at that position. Each lexicon contains reference words and associated control rules. When a processor matches a word in a field with a lexicon, 7, it verifies the word, 9, by use of the control rules. If incorrect, the word is re-written, 11. If no match is found in the lexicon set a flag is inserted in the field, 12. According to an indicator, 13, processing may be interrupted, 14, for manual input of an instruction, or the flagged field may be written to a print file, 15, for later attention. Efficiency is considerably improved by use of a number of lexicons as opposed to a full data dictionary, by assigning lexicon priority orders, and by insertion of additional fields, 18, according to the contents of existing fields, 17. <IMAGE>
