Abstract: 949,480. Electric phase measurements. DECCA Ltd. July 4,1962 [April 20,1961], No. 14336/61. Heading G1U. [Also in Division H4] In a phase comparison navigation system (see Division H4), wherein four stations normally transmitting frequencies 6f, 8f, 9f and 5f respectively, take turns to transmit all four frequencies simultaneously for a short interval, producing at a receiver a combined pulsed signal at a repetition frequency of 1f, the phase differences between the pulse signals from the four stations are measured on a long persistance C.R.T, Fig. 2, having a circular trace 28 produced by using as the X/Y deflection voltages, quadrature revolutions of the normal 6f transmission divided down six times in divider 26, Fig. 1. The pulse signals intensity modulate the C.R.T beam and the four stations therefore produce on the C.R.T screen, four spots 30, 31, 32 and 33, occurring at intervals but visible together due to the long persistance of the screen, and representing by their relative positions round the circular trace, the phase differences between the if output signals for each station. Such differences may be read directly as course lane positions by means of three suitably calibrated rotatable scales 35, 36, 37. The scales are all geared on the 6f spot 30. Specifications 656,108 and 765,573 are referred to.

[Class 97 (ii)] [See also Group XXXVI] A navigational compass comprises a magnetic element suspended universally at one end. The element aligns itself with the earth's magnetic field and indicates, preferably by a projected shadow, the azimuth direction and inclination of the supporting craft. In the form shown, a sealed hollow magnet 22 is attached at one end to a thread 33 passing through a fixed guide 27 and connected to a float 34. The guide 27 is fixed to a spherical glass receptacle 6, mounted in a cylindrical housing 1. The upper part of the housing 1, closed at the top by transparent plate 13 and at the bottom by a transparent plate 18 concave upwardly and the sphere 6 are filled with a liquid having a density equal to the mean density of the needle 22. A fixed graduated card 14<a> of translucent material and a transparent rotatable card 15 carrying a single radial mark are supported above the plate 13. A shadow of the needle 22 is projected on the card 14<a> by lamp 20 and lens 19. The inclination of the supporting vessel, e.g. an aircraft, is indicated by the length of the shadow and the direction of movement of the vessel by the direction of the shadow. A rolling ball 52 on the plate 18 may serve as additional means for indicating inclination. In a modification the lamp 20 may be arranged above the needle 22 and a shadow of the latter projected by a reflector and projecting lens on to a screen. The device is mounted in gimbals for use on ships and on the levelling screws 40 for use on land or on aircraft.

Title: Improvements relating to the production of corrugated sheets from plastic materials
IPC: B28B13/04
Filed: 1945-06-08
Abstract: 621,110. Moulding corrugated sheets of asbestos-cement. TURNER'S ASBESTOS CEMENT CO., Ltd., ROOKSBY, W. H., and BURGESS, T. June 8, 1945, No. 14586. [Class 87 (ii)] A preformed sheet 2 of material such as asbestos-cement is corrugated by feeding it, while in a plastic condition, from a conveyer band 4 on to a former 1 having corrugations extending transversely to the direction of movement of the conveyer band, and as a result of relative movement between the conveyer and the former the sheet is deposited without tension on the former. The sheet on the former is subjected, as the deposition continues, to vacuum from below, both to urge it into close contact with the former and to hold it in position, while a further part of the sheet is deposited. Additional pressure may be applied to the sheet by allowing a number of freely mounted rollers to pass over it, as it is being deposited (Fig. 5 not shown). Either the conveyer or the former may be moved to provide the relative movement. The speed of the conveyer band is so adjusted with regard to the relative speed of the conveyer and former that the rear end of the sheet is deposited on the rear end of the former. The suction unit 50, Fig. 4, of the former 1 comprises tubes 51 having holes 55 connected to the troughs of the corrugations and to the end wall of the first corrugation. The tubes 51 are connected by pipes 53 to a common suction pipe 54. Each pipe 53 has a manual control valve and a mechanically operated valve 57 which is normally closed. Each valve 57 is adapted to be opened by engagement with a shoe 61 fixed to the frame of the conveyer, so that as the frame moves to the right a number of pipes are successively put under suction. The shoe may be of such a length as to keep all the pipes under suction, until all the sheet has been deposited. Suction holes may also be provided in the crests or sides of the corrugations.

Title: New reaction products of epoxidized oils
Inventor: FYSH DERICK
IPC: C08G63/52
Filed: 1958-05-08
Abstract: Organic compounds containing antimony are prepared by reacting antimony trichloride with an epoxide obtained by epoxidizing an ester of an unsaturated fatty acid.  Preferred epoxides are epoxidized animal and vegetable oils such as epoxidized linseed, soya bean, sun flower, poppy seed, cotton seed and fish oils and esters other than glycerol esters of the fatty acids of these oils.  The antimony trichloride is preferably dissolved in a solvent and added slowly to a solution of the epoxide in a solvent such as chloroform or other chlorinated hydrocarbon.  The antimony-bearing product may be a tough rubbery gel.  It is considered that the epoxide ring opens whereby chlorine attaches to one side of the epoxide ring and the oxygen forms an antimony oxide link with the other side of the bridge.  The antimony chloride reaction products may be heated with an unsaturated polyester resin to produce non-inflammable polyester resins which contain antimony in the molecule.  The unsaturated polyester resins may be those produced from maleic or fumaric acid, or mixtures of the unsaturated acids and phthalic acid, with ethylene, propylene, diethylene or dipropylene glycols.  The antimony containing unsaturated polyesters may be cross-linked by unsaturated monomers such as styrene, other benzene derivatives, diallyl phthalate and methyl methacrylate.  Initiators such as cobalt naphthenate and methyl ethyl ketone peroxide are also used to facilitate casting of the resin.ALSO:Organic compounds containing antimony are prepared by reacting antimony trichloride with an epoxide obtained by epoxidising an ester of an unsaturated fatty acid.

Abstract: 557,207. Cracking oils catalytically. INTERNATIONAL CATALYTIC OIL PROCESSES CORPORATION. Nov. 20, 1941, 'No. 14948. Convention date, Dec. 26, 1940. [Class 32] In cracking oils in presence of a silicamagnesia catalyst suspended in the oil, the oil is fractionated to obtain a light gas oil fraction boiling in the range 550-750‹F and a heavier fraction have a mid-boiling point of above 725‹F; the light fraction is cracked at temperatures above 900‹F in admixture with the catalyst and the products obtained, after centrifugal removal of the greater part of the catalyst, are washed with the heavier oil to remove residual catalyst; the heavier fraction is then cracked in presence of the unregenerated catalyst from the first stage. Topped or reduced oil is vaporised in coil heated to 850‹F and the vapors are fractionated in tower 8 to recover the light gas oil fraction through condenser 22 and separator 24 and the heavy fraction through line 11, and bottoms through line 10. The light fraction is heated to 925-100‹F in coil 33 and mixed with catalyst from line 82 in an injector 36 is cracked in reactor 38. Catalyst is separated from the cracked products in separator 42 and the vapors pass to washer 16 where they are washed to separate residual catalyst by the heavy fraction supplied through line 15. This fraction is then heated to in coil 64 and mixed with unregenerated catalyst from the separator 42 supplied through injector 67 is cracked in reactor 72. The cracked products are separated from catalyst in cyclone 75 the catalyst being returned through regenerator 80 to the first stage while the vapors are mixed with the vapors passing from the washer 16 and fractionated in tower 49 to recover gaseous hydrocarbons, a heating oil, and a heavy gas oil through lines 50, 53, and 54 respectively. In an example an oil containing in suspension 1.65 per cent. silica-magesia catalyst (15-50 per cent. magnesia) is cracked at 911‹F for 12.4 seconds and a product is obtained comprising 48 per cent. gasoline and 51 per cent. gasoil.
