Abstract: 1,033,830. Diagnostic X-ray apparatus. GENERAL ELECTRIC CO. Ltd. March 18, 1965 [April 13, 1964], No. 15161/64. Heading H5R. A serial changer 7 (Fig. 1, not shown) for diagnostic X-ray apparatus, comprises a pair of channel-section guide members 9 (Figs. 2 and 3, not shown), each member enclosing an endless band 13 mounted on flanged wheels 11 at each end of the guides, such that a cassette inserted between the guide members is supported between the bands 13 which are driven by a reversible electric motor M, controlled by a plurality of switches, to move the cassette to different operating (exposure) positions. The motor drives wheels 11 on whose spindles 12 are mounted toothed sprockets 16, by a chain drive 17, through an electromagnetic clutch 10, and is controlled by the switches mounted at the end of and along one of the guides. A cassette or cassette carrier inserted at the loading end of the guides, between bands 13 which are biased inwardly by spring-loaded idler rollers 14, actuates a switch S 1  which starts the motor causing the cassette to move to a rest position at the other end of the guide, where a switch S 2  is actuated to stop the motor. After setting the exposure controls &c., a radiograph is taken by pressing a push-button switch to energize the motor M and drive the cassette from the rest position to the first operating position such that the first third of the film is located beneath the aperture 20 in an X-ray opaque screen 19 located above the changer. As the cassette moves, a switch S 3  is actuated to stop the motor when the cassette has reached the required position and to operate the X-ray tube to expose the film, after which the motor is again energized to drive the cassette back to the rest position where the switch S 2  is operated and a step-by-step rotary switch is simultaneously actuated to isolate switch S 3  and instead connect switch S 4 . For the next radiograph, the switch S 3  is unaffected by the movement of the cassette from the rest position, the switch S 4  controlling the stopping of the cassette in the second exposure position. A further switch S 5  stops the film for exposure of the third area of the film. The final operation of the stepby-step switch, after the three exposures, is to cause the cassette to be driven to the unloading position where it can be removed for development of the film. An over-ride manual switch is provided to drive the cassette from the rest to the loading position before all of the three exposures have been completed. The changer is mounted transversely across rails 4, along which it or a Bushy grid can be moved longitudinally by a motor to a position above the image intensifier 3 or fluorescent screen.

Abstract: 1,267,294. Laminated fabric. E.I. DU PONT DE NEMOURS & CO. 1 April, 1970 [1 April, 1969], No. 15528/70. Heading B5N. [Also in Divisions D1-D2] A non-woven web of crimped fibres bonded by a resin present in diminishing quantities from one face to the other is incorporated in a filling material comprising a laminate of like webs. Staple length crimped fibres 1 of linear polyesters such as polyethylene terephthalate, polyethylene terephthalate/isophthalate, polyethylene terephthalate/5 - (sodium sulpho)- isophthalate (9713) or poly(p - hexahydroxylylene terephthalate are garneted by rolls 2-5, then transported as a thin web by apron 8 to the cross-lapper comprising aprons 9 and 10. The cross-lapper makes pendulous back-andforth movements to deposit the web on to apron 11 which travels in the horizontal plane. Nozzles 17, 18 are operated on alternate halfcycles in order to spray the previously deposited layer with resin, so as to produce a laminate with 4 to 70 layers of web. An additional resin coating of the laminate may be applied. The half of each web nearest the sprayed face contains at least 701 of the total resin content, which is said to produce a laminate which is soft to the touch but has a high degree of support bulk, i.e. the ability to maintain a high proportion of original thickness under an applied load.  The resin is preferably a solution or an aqueous emulsion of ethyl acrylate methylmethacrylate N - methylolmethacrylamide, methacrylic acid and a cross-linking agent. Alternatively it may comprise other acrylics, melamines, polyvinyl chlorides, polyvinylacetates, polyesters, polyurethanes, copolymers of ethylene with other monomers, silicones, and flame retardant systems e.g. polyvinyl chloride plus tris 2,3-dibromopropylphosphate may be added. Multilayer products prepared without binder, or which comprise fibres having a core and sheath of different polyesters, the sheath being softened by heat to produce autogenic bonding, are described for the purpose of comparison.

Filed: 1974-04-09
Abstract: 1448411 Irradiation with ultra-violet light ELECTRICITY COUNCIL 9 April 1975 [9 April 1974] 15663/74 Heading H5R [Also in Division H1] Ultra-violet light is produced by causing a spark discharge between two electrodes to take place substantially wholly along the surface of a liquid. The discharge can be in air or nitrogen introduced through one of the electrodes. In Fig. 2, the liquid is in the form of a column 26 flowing between the electrodes, one of which has a funnel portion 30 for collecting the liquid. As shown in Fig. 2 the device is used to irradiate another liquid flowing vortically around the discharge and within the device but not in contact with the discharge. In Fig. 1 (not shown) a similar vortical flow of liquid to be irradiated is provided but the spark discharge takes place along the surface of this liquid with which the electrodes are in contact in this case. The flow of irradiated material is controlled in dependence on the spark repetition rate. The device can be used to irradiate external material by the provision of a suitable window.

Title: Improvements in or relating to television apparatus
IPC: H04N5/21
Filed: 1950-06-23
Abstract: 685,483. Radio receiving circuits. GENERAL ELECTRIC CO., Ltd., and BIGGS, A. J. June 20, 1951 [June 23, 1950], No. 15804/50. Class 40 (v). [Also in Group XL (b)] The visual effect of the high-frequency components of noise in a television signal is reduced by applying the signal to apparatus having a transmission characteristic which in respect of the high-frequency components of the signal is a function of the magnitude of these components so that the transmission thereof is reduced when these components are absent or of small magnitude. The invention is based upon a realisation of the fact that these noise components, which produce a shimmering effect in the reproduced picture, have a more noticeable effect upon those parts of the picture having little or no detail, i.e. those parts corresponding to low-amplitude high-frequency components of the video signal. In one arrangement, Fig. 1, a filter 1 separates the video signal into lowfrequency and high-frequency components which are applied through delay networks 2 and 3, respectively, to an output circuit 10. The high-frequency channel comprises also a switching diode 5 to which is applied a switching bias from a circuit 8 which develops a positive or negative output potential according to the amplitude of the high-frequency components applied thereto, a negative potential being developed as a result of a low-amplitude input and so switching off the high-frequency channel under these conditions. The delay networks are used to ensure that the diode is not switched off at the commencement of a sequence containing high-frequency components. In an alternative circuit, Fig. 2, for use in receivers, the low-frequency components derived from the anode of pentode 15 are applied to the grid 19 of cathode-ray tube 20 and the high-frequency components filtered from the signal developed across resistor 21 by differentiating networks 27, 31 and 33, 35 are applied, with opposite polarity, to the cathode 23 of the tube. Diodes 25 and 26 are biased through resistors 31 and 35, respectively, to beyond cut-off so that only signals in excess of a certain minimum amplitude are passed thereby.
