Title: Improvements relating to intersecuring attachments and fibre and like building boards
IPC: E04B9/24
Filed: 1949-03-28
Abstract: 692,084. Building boards; wall &c. linings. HAY, H. M. June 27, 1950 [March 28, 1949; Aug. 12, 1949; Dec. 21, 19491, Nos. 8347/49, 20998/49 and 32708/49. Classes 20(iv) and 87(i) [Also in Group XXV] Relates to securing attachments to fibre and like building boards or to securing the boards to supporting or stiffening members and consists in so guiding the limbs of the staples during driving that at least the end parts thereof are mutually inclined. The method is particularly applicable in the erection of ceilings, roof and wall linings and partitions. In securing angle laths a, Fig. 1, to one face of a fibre building board b to act as stiffeners, the limbs of the staple c are driven through holes d in one flange of each lath causing the limbs to diverge. To allow for slight relative shifting under varying climatic conditions a T-lath g, Fig. 4, suspended by hangers i may be secured to the boards by joggled strips h secured by staples as in Fig. 1. In another form the holes in the flange are elongated and the spreader holes are formed in small plates applied over the elongated holes. The board-supporting lath may be of channel-section j, Fig. 5, and the boards are attached by resilientclips k slotted at l for stapling at c. The part of the clip spanned by the staple is wide enough to cause spreading. Various forms of stiffener bars are shown, all of which are spanned by the staples and are wide enough to cause spreading The staples may be of sheet metal with widely separated limbs driven through holes d, Fig. 12, notches being provided at p to facilitate bending at these parts. In a modification notches p are provided at five places to cause a corresponding number of bends, Fig. 18. The holes may be spaced so that the limbs first converge and then cross and diverge. In a further form the limbs are curved. Sheet-metal staples may be bent up from a stamped-out sheet-metal blank so as to have three or more limbs and these may be caused to spread by being driven through holes shaped as at u. Fig. 27. Specification 530,192 is referred to.

Patent GB-466977-A (GB)
Title: Process for refining hydrocarbon oils
IPC: C10G21/18
Filed: 1936-03-23
Abstract: Hydrocarbon oils are freed from aromatics, hydroaromatics, and unsaturateds by countercurrent or batch treatment with one or more of the following solvents: ethyl oxalate, lactate, nitrate, or aceto-acetate; ethoxy ethyl acetate; methyl salicylate, formanilid, or propionate; butyl furoate, phenyl borate, triphenyl phosphate, benzyl phthalate; or mono-, di-, or tri-acetin, -propionin, or -butyrin.  The selective solvents may be mixed with auxiliary solvents of the following kinds: (A) those miscible in any proportion with the selective solvents and with the oil treated; examples are aromatic and hydroaromatic hydrocarbons, and non-selective aliphatic and aromatic halogenated derivatives, e.g. chlorinated hydrocarbons; they increase the solvent power and so the amount of extract, leaving a more refined oil; (B) those miscible with the selective solvent but not or only slightly with the oil; examples are alcohols, water, and organic acids; they decrease the solvent power and so the amount of extract, which is desirable when treating naphthene-base oils; (C) those miscible only with the oil; examples are propane, butane, or other low-boiling paraffin; they sharpen the selective power. Dewaxing, before or after extraction, may be effected by chilling and centrifuging, filtering, or decanting, using as diluent a mixture of such proportions of a selective solvent and an auxiliary solvent of type A or C that the solvents do not separate from each other on chilling.  The slack wax may be refined by treatment with the same or other solvent mixture.  Recovery of the solvents from the raffinate, extract wax or dewaxed oil is effected by distillation or by extraction with solvents not dissolving the oils or wax. In examples, a dewaxed distillate is batchextracted at 86, 86, 120, and 160 DEG F. respectively with 1 vol. of ethyl acetoacetate each batch, and clay-treated at 450 DEG  F., or with 1 vol. of ethyl lactate each batch at 120, 160, 194, and 230 DEG  F. respectively.

Filed: 1951-04-13
Abstract: The ultra-violet light stability of polydienesulphur dioxide threads is increased by passing the thread during its manufacture in a number of consecutive turns over one or more thread-advancing, thread-storage devices and subjecting the turns of thread to an extensive washing treatment with a liquid consisting essentially of an alcohol.  The polydiene may be polybutadiene or natural rubber. The thread-storage devices are preferably reels of the type described in Specifications 413,413, 413,414, [Group IX], and 474,974.  The alcohol, which may be ethanol, methanol or isopropanol, on the thread-storage device preferably flows in counter-current to the direction of travel of the thread.  The washing step may be followed by the incorporation of heat-stabilizing agents such as those disclosed in Specifications 666,640 and 684,967.  In examples, masticated rubber in toluene is activated with tertiary butyl hydroperoxide and then extruded into a coagulant bath containing sulphur dioxide dissolved in a mixture of ethanol and toluene; the resultant thread is passed to a take-up godet and then over three cantilever thread-advancing reels on the first two of which the thread is washed with ethanol.  On the third reel the thread is washed with ethanol alone, or with ethanol containing either thiourea and hexamethylene tetramine or phenyl salicylate.  Specifications 527,075, 616,276, and 679,274 also are referred to.ALSO:The ultra-violet light stability of polydiene-sulphur dioxide threads is increased by passing the thread during its manufacture in a number of consecutive turns over one or more thread-advancing, thread-storage devices and subjecting the turns of thread to an extensive washing treatment with a liquid consisting essentially of an alcohol.

Abstract: 1,182,658. Measuring velocity and particle size. BRITISH AIRCRAFT CORP. Ltd. Sept. 30, 1968 [Oct. 4, 1967], No.45258/67. Heading G1A. In a method and apparatus for measuring the velocity or size of particles suspended in a moving fluid or affixed to a moving surface, a pair of coherent light beams produce a pattern of fringes in the fluid or on the surface and spaced apart in the direction of particle movement, and movement of each particle across the fringes produces a periodic fluctuation in the amount of light absorbed or reflected by the particle which is detected by a photo-detector, the constantly changing path length between the particle and the detector producing a Doppler variation in the frequency of the periodic fluctuations in the detector output to indicate particle velocity and the magnitude of the fluctuations being representative of particle size. The source may be two commonly supplied lasers, or a laser beam may be passed through a pair of slits or a thick beam splitter and focussed on to the surface or into the fluid. The apparatus may be applied to measurements in wind or water tunnels, or to steel strip emerging from a rolling mill. A mathematical analysis is included.

Abstract: 424,735. Valve circuits for wireless reception. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. March 22, 1934, No. 9024. Convention date, May 18, 1933. [Class 40 (v)] The grid bias of one or more of the valves of an amplifier is caused to vary according to the strength and the frequency of the signals to which the amplifier is tuned. As shown, the grids of the controlled valves are connected to a point e on a resistance R4, one end of which is connected to the load resistance R3 of a diode 3 which rectifies the signals and the other end being connected to a variable tapping d on a potentiometer R5, R1 connected across a D.C. source 1, 2. Thus the potential of the point e is dependent on the strength of the rectified current in the resistance R3 and on the position of the slider d which is ganged to the tuning control of the amplifier. A permanent positive potential is applied to the anode of the diode 3 from a point a on the resistance R1 through a resistance R2 so that the anode never becomes negative whatever the position of the slider d. A modification is described, Fig. 2, (not shown), in which the automatic gain control is applied to one only of the amplifying valves.
