Patent GB-2118344-A (GB)
Title: Coin testing apparatus
Inventor: DEAN ROBERT
IPC: G07D5/00
Filed: 1982-02-12
Abstract: The operation of a coin testing apparatus is checked by switching the apparatus to a test mode. In the test mode, the properties of items inserted into the apparatus are compared with stored «test» ranges, instead of «acceptability» ranges which are normally used to determine whether the item is a genuine coin. A specially designed non-genuine coin is then inserted into the apparatus. If the measured properties of the non-genuine coin fall within the «test» ranges, a signal is produced to indicate that the apparatus is operating correctly. If any of the properties falls outside a «test» range, but within a further, contiguous range, a signal indicates that the apparatus is working adequately, but not optimally.

Title: Tensioning device
IPC: F16G11/12
Filed: 1982-03-05
Abstract: In a tensioning device with a screw device consisting of a screw sleeve (2) surrounding a screw spindle, there is a rotation block which has a blocking element (9) permitting unimpeded tensioning of the tensioning device, but preventing undesirable release of the tensioning device by engagement with a groove (8) in the screw sleeve (2). The blocking element (9) is under the action of a spring (15), the force of which has to be overcome, when the tensioning device is released, by actuating an unlocking member (14). <IMAGE>

Patent GB-2130092-A (GB)
Title: Method and apparatus for illuminating cavities
Inventor: DIETRICH RALPH
IPC: A61B5/00
Filed: 1983-08-23
Abstract: The present invention relates to a method and apparatus for the uniform and simultaneous illumination by means of radiation of the interior surfaces of cavities for the purpose of observation and/or irradiation. In particular, such cavities may be not only hollow organ cavities, but also cavities in non-organic objects. The solution provides that the interior of the cavities is filled, at least in part, with a light scattering or dispersing medium and the dispersing medium is caused to shine or scatter light by means of one or a plurality of radiations or scattered light. With the integral irradiation used according to the present invention, two procedures are combined technologically, namely diagnosis and therapy of, for example, carcinoma in organ cavities which have been photosensitized by chemical substances, possibly on the basis of differences in decomposition of cancerous and normal tissue.

Patent GB-2461329-A (GB)
Title: Controllable transponder
Inventor: CHEKROUN CLAUDE
IPC: G01S13/75
Filed: 1984-03-06
Abstract: A microwave transponder has three wire-diode arrays 1,2,3 arranged in trihedral configuration, each array comprising a sub-array of parallel rows of wires interrupted at intervals by diodes controllable such that the array is reflecting when the diodes are reversed biased and transparent when the diodes are conducting. The array may be in the form of a grid having X and Y sub-arrays whereby it is insensitive to the direction of polarisation of the received electromagnetic wave and operates irrespective of the electric field in space. By modulating the coefficient of reflectivity of the three arrays, coded data may be added to a reflected signal so providing e.g. a means of identifications recognisable only by "authorised" equipment. Also supplementary arrays 7 preferably convexly curved may be used to render the transporter effectively invisible to search radar, when set in the reflective mode.
Patent GB-2140561-A (GB)
Title: Ultrasonic testing apparatus and a method of ultrasonic testing
Inventor: BOWYER WILLIAM HENRY
IPC: G01N29/06
Filed: 1984-05-24
Abstract: The apparatus comprises a flaw detector (1) and scanning head (2) for directing test ultrasonic pulses into a sample under test and for receiving ultrasonic signals from the sample. Analogue-to-digital converter means (4) are provided for converting analogue electrical signals from the flaw detector (1) into digital signals at the same rate as the ultrasonic signals are received by the flaw detector (1) and a plurality of memory means (6) are arranged to store temporarily digital signals output from the converter means. Control means (5) pass digital signals corresponding to the ultrasonic signals produced by a given test ultrasonic pulse into a respective memory means so that the digital signals corresponding to ultrasonic signals produced by successive ultrasonic pulses are stored in different memory means and means (7) are provided for comparing the digital signals temporarily stored in one memory means with the digital signals temporarily stored in one or more other memory means to produce output digital signals for producing an indication of any defect in the sample under test. The apparatus effectively reduces the "noise" or "grass" in the received ultrasonic signal, especially that due to grain boundaries in alloys. The received ultrasonic signal may be reduced in frequency before conversion to a digital signal. <IMAGE>

IPC: G01L27/00
Filed: 1985-06-07
Abstract: This method for the dynamic calibration of pressure measurement circuits comprising a piezo-electric quartz pressure transducer, a charge amplifier and a digitizing device consists in using a source 1 of inert gas under a determined high pressure which is slightly higher than the calibration pressure. The exact pressure of this gas is determined with high accuracy by using a dead weight tester 3. This source of inert gas is also employed to pressurize oil and the high oil pressure is transmitted to the pressure transducer, which is alternatively subjected to this high oil pressure and to atmospheric pressure by a device 10. <IMAGE>

Title: Infrared photodiodes, arrays and their manufacture
Inventor: JENNER MICHAEL DAVID
IPC: H01L27/148
Filed: 1985-09-11
Abstract: A compact infrared photodiode has its p-n junction (12) located in a plane to intersect the two opposite major faces as well as the two side faces of the diode body (10) and thereby to divide the body (10) throughout its width and thickness into the ptype region (1) at one end and the ntype region (2) at the opposite end. The body has small dimensions, e.g. a thickness of less than 5 mu m and a width and a photosensitive length of less than 20 mu m, as to avoid the provision of excess body material around this p-njunction plane, thereby reducing thermal generation of carriers which would contribute significant noise to the photodiode signal. These small body dimensions and the p-njunction orientation permit the formation of a cadmium mercury telluride photodiode operating at or near room temperature for the detection of infrared radiation (30) in the 3 to 5 mu m or even the 8 to 14 mu m wavelength band. The body thickness may be as small as 1 to 2 mu m, but preferably a reflector (21) is provided at one major face of the body (10) to increase the photoabsorption efficiency for infrared radiation (30) incident at the opposite major face. A wide optical immersion lens (40) may be coupled to a major face of the narrow photodiode body (10) to increase the radiation collection efficiency; a multiple lens arrangement is particularly suitable for arrays of the photodiodes. <IMAGE>
