Title: Capacitance displacement transducers
Inventor: ASBERY JOHN HARRISON
IPC: G01D5/241
Filed: 1984-01-03
Abstract: A capacitance displacement transducer, exemplified by a rotary type in Fig. 3, comprises a pair of members in the form of discs one of which 12, is fixed and the other of which is rotated by a shaft. The disc 12 has two series of conductive strips 16,17 the strips being radially disposed and alternately arranged. The strips of each series are connected to respective connection points 18, 19 which in use are of opposite electrical polarity. The rotary disc has a further series of strips arranged in like manner to the series of strips 16,17, but the number of strips on the rotary disc being half the number on the disc 12. The discs are in close proximity so that as the rotary disc rotates the polarity of the strips thereon will vary. <IMAGE>

Title: Optical Data Retrieval System Using Multi-Spectral Light Sources
Inventor: DREXLER JEROME
IPC: G11B7/24
Filed: 1984-02-09
Abstract: An optical data retrieval system features probe beams of different wavelengths directed onto an optically reflective recording medium 11 having different spectral responses to the probe beams. A first probe beam 19 is directed onto the reflective medium 11 in a manner such that the amount of light reflected from the medium 11 may be detected while a second probe beam 29 is directed through the medium 11 in a manner such that the amount of light passing through the medium 11 may be measured. Different amounts for both beams 19, 29 are detected at pits 23 in the medium 11 and in the reflective field surrounding the pits 23. The redundancy provided by two probe beams 19, 29 eliciting different spectral responses from the medium 11 reduces errors due to dirt and media defects. <IMAGE>

Title: Ink drying apparatus
Inventor: PALMER ARTHUR ROLAND
IPC: F26B3/28
Filed: 1984-04-24
Abstract: Apparatus for drying printed ink comprises an emitter of infra-red radiation at a wavelength of between 2.5 mu m and 12.5 mu m. The preferred wavelength emitted is between 3 mu m and 6 mu m, and the infrared emitter is advantageously a ceramic radiation element 4 heated to a temperature between 300 DEG C and 700 DEG C. The apparatus comprises a conveying means 1 for transporting T-shirts and other garments to be printed with ink past the emitter, and the conveying surface is advantageously sloped off each of its opposite longitudinal edges so as to present for example the printed front of the garment closer to the emitter than the unprinted arms of the garment. Uniform curing of the ink is promoted by a fan which circulates air over the printed material. <IMAGE>

Title: Arrangement in a swivel connection between two fluid transporting conduits
Inventor: ANDVIG TORE
IPC: F16L39/06
Filed: 1984-04-30
Abstract: In a swivel connection between two fluid transporting conduits 3, 7 rotatably mounted on one another, a connection between hydraulic control conduits (14, 16 Fig. 4) rotating together with the fluid transporting conduits is provided through a slim shaft 18 which is coaxially positioned within one conduit 3 and extends into a sleeve (17) supported by the other conduit. Thereby the diameter of the coaxial sliding surfaces for transmitting control fluid may be made substantially smaller than the diameter of the fluid transporting conduits, which substantially reduces the problems associated with obtaining a reliable swivel connection between hydraulic high pressure conduits. <IMAGE>

Title: Diagnosis of malignant tumours by fluorescence
Inventor: KUN ZENG
IPC: A61B5/00
Filed: 1986-07-07
Abstract: In a non-invasive apparatus for the diagnosis of malignant tumours by intrinsic fluorescence UV light from a source 1 is transmitted by quartz optic fibres 2 to the surface of the living tissue 3, stimulating its intrinsic fluorescence which is transmitted by ordinary optic fibres 4 for signal processing and subsequent display of the intrinsic fluorescence spectrum by graphical means. The presence of the characteristic wave peak in the graph corresponding to evidence of malignancy permits appropriate diagnosis. The colour of the intrinsic fluorescence of the living tissue which determines the presence or absence of malignancy, may also be made with the naked eye. The apparatus may be used clinically to diagnose body surface malignant tumours, as well as those in body cavities within the reach of the optic fibres. <IMAGE>

Title: Improvements relating to parachutes
Inventor: AVIS KEVIN PAUL
IPC: B64D17/14
Filed: 1988-08-12
Abstract: A parachute having a canopy which has inherent drive means which provides lateral thrust in use and which supports a load or parachutist through rigging lines has means 10 for causing the canopy to descend to ground or sea level when the load/parachutist lands with the initial orientation of the canopy such that the drive means acts to urge the canopy upwardly. This may be achieved in several ways by for example causing the canopy to rotate about the rigging lines, e.g. by a non- symmetrical slot 12, so that the thrust from the drive means no longer acts to urge the canopy upwardly. It is also possible to reduce or remove the drive thrust upon landing by suitable means to allow the canopy to descend. <IMAGE>
Patent GB-2209070-A (GB)
Title: Humidity and ventilation control
Inventor: HUDSON ALAN CHARLES
IPC: G05D22/02
Filed: 1988-08-23
Abstract: To prevent dam and mould in a well-insulated modern house, humidity control is often necessary, but causes customer concern. In the invention, humidity control is provided by using a fan 14 in a cooker hood 10, venting to an outside wall 13. The fan is turned on when the general house humidity rises too high, as sensed by a humidity sensor 20, which is preferably of a self-cleaning type. It is also controlled by a conventional manual 4-position (off plus 3 speeds) control switch 15, and by a cooking temperature sensor 22. The humidity trigger level may be varied in dependence on the ambient temperature (sensed by a temperature sensor 21). A second humidity sensor (40, Fig. 2) may be located e.g. in or near a bathroom. This preferably has low sensitivity, but sets the fan to high speed; the sensor 20 will then sense the damp air being drawn from the bathroom and continue extraction (at low speed). Any suitable type of heat exchanger can be used in place of the simple wall vent 12. <IMAGE>
