Title: Training apparatus for radar operators
Inventor: CUTLER ALBERT ERNEST
IPC: G01S7/40
Filed: 1953-10-01
Abstract: 750,628. Photo electric radar trainer. COMMUNICATIONS PATENTS, Ltd. Sept. 29, 1954 [Oct. 1, 1953], No. 26970/53. Class 40 (3). [Also in Group XL (c)] A radar trainer which includes means for providing on a viewing screen synthetic representations of echoes received from features on the earth's surface comprises a chart 3 on which radar features of the terrain are represented by areas which transmit light to different extents, a source of light, and means for detecting the energy transmitted by portions of the chart and applying corresponding signals to effect corresponding areas of the display means. The light may be generated by scanning the screen of cathode ray tube 4 with a constant intensity beam under control of scanning generator 5. Photo-electric cells 6 on the opposite side of the chart pick up the light transmitted by the chart at the point opposite the screen spot and provide electric signals which are amplified at 7 and applied to display cathode ray tube 8 which is scanned in synchronism with tube 4. A reproduction of the terrain chart is therefore obtained on display tube 8 where it may be combined with other indications. If the radar is assumed to be moving the map may be moved with respect to the tube 4 by means of suitably controlled lead screws. If the radar aerial support is assumed to be a vehicle capable of turning tube 5 may be arranged to rotate in accordance with the supposed angular movement of the vehicle. In a modification (Fig. 2, not shown) the chart surface is made to vary in reflecting power and the spot from the scanning tube is projected on to it and the light reflected determined by photo-cells. The map for this embodiment can be made much larger than in the first embodiment. The arrangement of the present invention does not take distance variations, due to the supposed altitude of the radar above the terrain, into account. Means to do this are described in Specification 750,685.

Title: Improvements in and relating to apparatus for use in the manufacture of endless belting
IPC: B29D29/00
Filed: 1931-09-28
Abstract: 390,163. Driving-belts. GOODYEAR TIRE & RUBBER CO., 1144, East Market Street, Akron, Ohio, U.S.A. Sept. 28, 1931, No. 27023. Convention date, Feb. 27. [Class 80 (i).] Relates to the manufacture of flat or V-belts having a tension-element of cords applied under tension to the surface of belting, which is preferably of rubberized fabric and is finally wrapped around and encloses the cords. A motor 14 drives pulleys 12, 20. A conveyer belt 13 is carried upon pulleys 11, 20. The spindle 21 of the pulley 20 is carried in bearings 22, 23, one 23 of which may be disconnected from the spindle and moved aside to allow access to the pulley 20. A second pulley 51 is carried in similar disconnectible bearings on a member adjustably secured in a slide 33 adjustably secured on the frame 10. An endless band 52 of rubberized fabric, preferably bias-cut, is placed around the pulleys 20, 51, and the slide 33 is adjusted until both sides of the band are supported on the conveyer belt 13. Cords 57, 66, wound on braked drums 54, 55, pass through tensioning-means to pulleys 61, 69, Fig. 9, on a stationary axle 62, on which they are braked by blocks 70, 71, and thence to pulleys 64, 73 loose on a shaft 65 driven from the motor, the pulleys 61, 64 and 69, 73 being interconnected by gears 110, 111. The cords then pass on to support in their loops tensioning-discs 81, 98 sliding in vertical grooves 82 in the frame. The discs maintain a constant tension in the cords, but, when they fall into contact with the ends of levers 90, 99, solenoids are excited and move clutch-operating levers to remove clutch discs 75, 76 from their normal engagement with the pulleys 64, 73 and thus stop the cord feed. The cords 57, 66 are stitched to the centre of the face of the band 52 and are guided to form a layer of convolutions, contiguous or spaced, as the band 52 is carried around the pulleys 20, 51 by the conveyer belt 13, by grooved rollers 162 carried in spring-pressed levers 160 pivoted to nuts 152, 153 on a right- and left-hand screw 145 turned by a hand crank 158, which is reversed as the levers 160 reach the limits of their movement. During the winding of the cord, the band 52 is gradually tightened by slight buckling action. When the cord layer or layers is complete, the ends of the cord are out and the edges of the band 52 are manually folded about the cords, overlapped, and stitched together. The belt is then vulcanized. The nuts 152, 153 may be provided with pivoted screw-engaging parts to facilitate their rapid adjustment along the screw. A cord may be wound upon a band closely fitting a collapsable mandrel, the guiding-screw being driven by a belt, instead of by hand. The belt is subsequently cut into narrow strips to form V-belts.

Title: Preparation of glycerol
IPC: C07C29/66
Filed: 1960-08-04
Abstract: Glycerol is prepared by the hypochlorination of allyl alcohol with chlorine in aqueous solution to produce aqueous glycerol chlorohydrins which are then hydrolysed with sodium carbonate to produce aqueous glycerol from which anhydrous glycerol is separated by vaporisation of the water and separation of the salt, the aqueous glycerol chlorhydrins from the hypochlorination step, before being submitted to hydrolysis, being neutralised with sodium hydroxide or sodium carbonate to a pH of about 4 to 5 and then fractionally distilled so as to remove impurities which distil out with water at temperatures up to the boiling-point of water.  The glycerol obtained after vaporization of the water and separation of the salt may then be distilled to remove overhead unreacted glycerol chlorhydrins which may be recycled to the hydrolysis stage.

Filed: 1972-06-12
Abstract: 1356751 Digital transmission; master and slave systems HYDRIL CO 12 June 1972 [29 June 1971] 27441/72 Heading H4P In a system having remote units each identified by a separate address and working to a central station, to reduce the number of bits retransmitted to the central station the prime data plus address is operated on by a polynome embracing a code such as Bose Chaudhuri (B.C.) to produce a remainder which is transmitted after the data to form a continuous message ending with the BC code. Before retransmission of a message back to the central station the remote unit cycles its own address through a BC generator the remainder from which is retransmitted to the central station, which then performs a BC check on the incoming message having already processed the remote station address during initial transmission time hence if the correct remote station responds there is agreement between the two sets of signals. If there is no agreement incoming data is rejected and the operation is repeated. At the transmitter, a source (10) (not shown) produces a message D1 (x) which is transmitted together with address data An (x) plus a check character R1 (x) which is derived as a "remainder" by dividing D1 (x) and An (x) by a prime polynome, e.g. BC code. The two parts are divided on reception by a polynome G (x) in generator 19 hence if the message is received without error then the remainder due to this division equals zero at output 20. This process is described in USA Specification 3,336,467.  Message data source 16 produces return data D2 (x) and address generator 17 produces An (x) this being operated on by means (not shown) to produce R2 (x) the parts D2 (x) + R2 (x) being retransmitted to the central station for check. If the remainder is not zero i.e. an incorrect station has responded the original message may be repeated.

[Also in Group XXX] A homogeneous emulsion consisting of liquid containing gas and flocculatable solids and produced, e.g., by the process of Specification 730,632 is fed down an inclined plane 2 to a tank 1 for the separation and removal of solids containing foam. The foam collecting at the surface is removed by scrapers 4 on two endless chains 5, Fig. 1, passing over sprocket wheels 6, 7, whose axes lie in a plane slightly inclined to the horizontal so that the lower edges of the scrapers emerge from the liquid surface half way along the tank. Beyond the inclined plane 2 a horizontal surface 3 is provided of length sufficient to accommodate two adjacent scrapers 4, between which the foam rises. The rate of advance of the chains 5 is equal to or less than the rate of drainage of liquid from the foam (e.g. 40 cms/min.), and the drained foam is removed over a ramp 16. Liquid containing siliceous and like solids passes down conduits 12 to a pipe 10. The tank floor may comprise(s) inverted square pryamids followed by a trough-shaped portion, Fig. 1, or followed by a flat portion ; or a row (or several juxtaposed rows) of inverted pyramids ; or two parallel troughs 29, Fig. 14, each communicating by a continuous gutter 27 with a pipe 28 ; or by a single trough of the same kind having steep, shallow or horizontal sides. To ensure removal of the heavier solids the pipes 12 have different cross-sections or inserted entrance-rings while the pipe 10 has progressively-increasing cross-sections from the righthand end to the liquid discharge, Fig. 5. The pipe 12 may have valves. The liquid level may be controlled by immersed electrodes or by a photo-electric cell 23, Fig. 10, illuminated at 21 through a transparent member 20 extending from the ramp 16 and through either foam (relativley opaque) or clear liquid passing over it. The scrapers 4 may be spaced at conventional intervals or at short intervals (8 to 10 cms.), in which case they are provided with backwardly-directed spacers 24, Fig. 12 (plan), which ensure the collection and removal of the foam in the form of cubes. The scrapers may be washed in a container beyond the foam-shoot 8 and they may be provided with slots 31 in their lower parts or in covering plates 32 on flanges 33, Fig. 16. The pipes 28, Fig. 14, may accommodate Archimedean screws. The tank 1 may be surrounded by a closed chamber in which heating fluid (e.g. steam) or cooling fluid may be circulated. The horizontal surface at the inlet 3 may be preceded by a transverse trough, Fig. 17 (not shown), The collected foam may be de-aerated by a centrifugal pump followed by a heated rotary filter.
