Title: Radar simulation apparatus
IPC: G09B9/40
Filed: 1972-07-31
Abstract: 1371239 Radar simulation REDIFON Ltd 31 July 1972 [30 June 1971] 30672/71 Heading H4D Apparatus for simulatinga weather radar comprises an optical transparency having areas or different density, means for scanning the transparency and forming an image which is viewed by a photo-electric device which thus supplies corresponding electrical signals to an amplifier and display means, wherein betweeen the transparency and photo-electric device is placed a photo-chromic plate which is darkened or bleached locally by short or long wavelength light sources. The transparency, Fig. 2, has areas of differing density ranging from opaque 24 to transparent 25<SP>1</SP>, 28<SP>1</SP>. The plate thus represents a basic pattern of a storm complex. The cells 25-28 do not remain static however but decay on the downwind edge and form on the upwind edge of the squall line. In the apparatus, Fig. 1, used in a ground-based aircraft simulator, transparency 1 is scanned via lens 3 (or a fibre optic interface) by the radial PPI scan of CRT 2. The image is viewed by photomultiplier 4 which supplies signals to display tube 23, having a radial PPJ scan synchronous with tube 2. In order to effect the changing weather pattern, a CRT 11 having an ultra-violet emitting phosphor is used to darken photo-chromic plate 6, according to required patterns. CRT 14 has an infra-red emitting phosphor and is used to bleach out darkened areas if necessary. The scanning of these tubes 11, 14 may be of the TV type. Infra-red source 17 is used to flood the plate 6 at the start of the exercise. Filters 9, 18, 19 prevent unwanted radiation reaching the plate 6 and photo-multiplier 4. In order to represent motion of the aircraft, the origin of the PPI scans of tubes 2 and 23 may be variable. The display (Fig. 7, not shown) shows the areas of precipitation associated with the storm and may be provided with equisignal amplitude contours by data processing unit 22, Fig. 1.

Filed: 1926-12-06
Abstract: 288,352. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Dec. 6, 1926. Presser-bars with periodic control.-Means comprising co-operating wedge blocks provided for locking the presser-bar during the stitch formation. Fig. 1 shows the application to a boot-sole sewing-machine as described in Specification 23478/10. The presser-foot 8 is mounted on a lever 10 pivoted at 12 and having at its other end a pivoted link 16 which has pivoted to it a wedge block 14. One edge of the block bears upon a fixed guide 18, and the other bears upon the edge of a locking wedge block 20 which works against a fixed guide 22. The block 20 is connected by a link 24 to one arm of a lever 26 which is pivoted at 28 and is pulled by a strong spring 30. The gap between the guides 18, 22, diverges upwardly so that, under the action of the spring 30, the wedge block 20 forces up the block 14 to press the foot 8 upon the work and lock it there. The device is self-adjusting for different thicknesses of work. The lock is opened to permit of the work being fed by a bar 34 which, when depressed, acts on a pin 36 on the lever 26 in order to draw down the locking wedge 20. The foot 8 may then press lightly on the work, or may be lifted off the work. The bar 34 is depressed periodically by a lever 44 which is pivoted on a stud 46 and is actuated by a cam disc 50 on the main shaft 52. The connection between the lever 44 and the bar 34 comprises a gripping lever 42 pivoted to a loose sleeve 38. The lever 42 has an eccentric face which ceases to engage the bar when, at the end of the upward movement, the sleeve 38 contacts with a fixed stop 57. A light spring 54 is arranged between the sleeve 38 and a block 55 adjustably clamped to the bar. When it is desired that the foot 8 should be lifted off the work during each feeding movement, the block 55 is adjusted so that it will engage a pin 58 on the wedge block 14 connected to the presser-bar. If the block 55 is (adjusted so that it does not engage the pin 58 during the movements of the bar 34, the presserfoot will be held lightly in engagement with the work while it is being fed. The presser bar may be lifted manually by pressing upon a lever 72, or automatically upon stopping the machine by a link 78 which operates as described in Specification 1021/14. The lever 72, which is pivoted on the stud 12, has an arm connected to a link 74, the slotted end 76 of which engages the pin 36 of the unlocking lever 26. Governing needle thread.-The thread guiding eyes 60, 61, which co-operate with a pull-off arm 66, are positioned by an arm 68 and a link 70 connected to the presser-bar locking lever 26 so that the length of thread pulled off will vary with the thickness of the work.

Patent GB-621520-A (GB)
Title: Manufacture of carboxylic acids
IPC: C07C51/10
Filed: 1946-10-16
Abstract: Carboxylic acids are produced by subjecting halogenated hydrocarbons, carbon monoxide, and water to an elevated temperature in presence of a metal carbonyl.  Nickel carbonyl itself may be used to supply the carbon monoxide or carbon monoxide may be used with nickel carbonyl, a nickel halide, especially a hydrate such as NiI2.6H2O, or other carbonyl-forming form of nickel.  Nickel mixed with copper iodide is equivalent to nickel halide.  Other carbonyls specified are cobalt and iron.  Pressures may be 40-500 atmos.  With methyl chloride, temperature is suitably 250-350; with methyl iodide 180-200 DEG  C. Halogenated hydrocarbons of more than one carbon p  atom require lower temperatures.  With chlorinated or brominated hydrocarbons, the presence of iodine is advantageous, for example with methyl chloride, 1/2 -1\ba1/2 mole. per cent, added as such or as methyl, hydrogen or nickel iodide.  The molar ratio of water to halogenated hydrocarbon may be 1 to 3 : 1, and of carbon monoxide to halogenated hydrocarbon 2 to 4 or more: 1.  The reaction may be effected under acid conditions by adding organic or inorganic acids, for example acetic or hydrochloric.  The production of acetic, propionic, butyric and adipic acids from methyl, propyl or butyl chloride or 1,4-dichlorbutane respectively is referred to.  Methyl chloride may be obtained by reaction of methane with chlorine or, preferably, hydrogen chloride and oxygen or air in presence of such a catalyst as cuprous chloride. Preferably, excess of methane is used to suppress formation of more highly chlorinated products.  Ethyl chloride may be obtained from ethylene and hydrogen chloride with zinc chloride as catalyst.  In an example, methyl chloride is reacted in presence of nickel carbonyl and iodine at a temperature of 330 DEG  C. and a pressure rising to 350-450 atmos.
