Title: Improvements in or relating to plant for producing a flow of gas under pressure and to aircraft including such plant
IPC: B64C29/00
Filed: 1962-05-17
Abstract: 972,561. Controlling aircraft. D. B. SPALDING. April 29, 1963 [May 17, 1962], No. 19147/62. Heading B7G. [Also in Division F1] A plant for producing a flow of elastic fluid includes a sliding-vane air motor coupled to rotary fan or compressor. For the purpose of stabilizing a vertical or substantially vertical lift aircraft, air, by-passed from the compressor of gas turbine engine 17 in wing 18, is fed through a control apparatus 9 to a sliding-vane air motor 11 driving an axial-flow fan 13 which delivers air at a pressure of 1 to 3 p.s.i. (gauge) through a stabilizing nozzle 14. The control apparatus 9 contains an instability sensing device which meters the required correcting flow of air to the motor 11 which may exhaust direct to atmosphere or through the nozzle 14. Two or more nozzles 14 may be provided each with a motor 11 and fan 13. The air for the motor or motors 11 may be supplied by more than one compressor and, provided a non- return valve is included in each high-pressure air supply duct, this reduces the possibility of loss of stability on the failure of one engine. The fan of the sliding-vane air motor and fan unit may be employed as an anti-torque rotor of a helicopter. In an alternative embodiment shown in the Provisional Specification, the air flows from the engine compressor direct to a sliding-vane air motor driving a fan which delivers air through a control apparatus to a series of stabilizing nozzles.

Title: Process for preparing organohalosilanes
IPC: C07F7/16

Abstract: Organohalogenosilanes are prepared by passing a mixture of an organic halide RX. wherein R is a monovalent hydrocarbon radical and X is halogen atom and 0.1 to 10 mole per cent. of AlCl3 through heated powdered silicon, which silicon is the residue produced by heating a mixture of powdered silicon, a metal catalyst and an organic halide until 50% to 90% of the silicon has been reacted.  The silicon powder may have a particle size of 20 to 200 microns. Specified organic halides are of the formula RX where R is methyl; ethyl; propyl; butyl; octyl; phenyl; naphthyl; tolyl; xylyl; phenylethyl; benzyl; vinyl; allyl; alkenyl; propynyl; cyclohexyl; cycloheptyl; cycloheptenyl and cyclohexenyl and X is halogen e.g. chlorine or bromine. Specified organohalogenosilanes are of the formula <FORM:0947841/C3/1> where n is 1 to 3 and include methyltrichlorosilane; dimethyldichlorosilane, diphenyldichlorosilane; trimethylchlorosilane; phenyltrichlorosilane; triphenylchlorosilane; diethyldichlorosilane; dibenzyldichlorosilane and vinyltrichlorosilane.  A reaction temperature of 250 DEG  to 350 DEG C. is used. In the example a reactor is charged with a silicon powder, 60% of which had already been reacted and having 30% by weight of copper as catalyst, and methyl chloride is passed in at a temperature of 260 DEG C. and the product gases analysed. A sublimation chamber containing AlCl3 was then heated to 106 DEG C. and a mixture of CH3Cl and AlCl3 vapours was passed through the silicon powder.  Percentage yields of dimethyldichlorosilane in the product stream with variation in temperature of the sublimer and mole per cent. of AlCl3 in the gas mixture are given.

[Class 98 (ii)] A bi-pack material comprising one support bearing two silver halide emulsion layers sensitive to two different spectral regions and separated by a filter layer stable to the photographic baths, and another support bearing a single emulsion layer sensitive to the remainder of the spectrum is developed, and in the twolayer element the silver is dissolved out and the silver halide images are converted into colour images by means of separate exposures using the filter layer and monochromatic light. The filter dyestuff is bleached out after the production of at least one coloured image. The filter dyestuff may be 1 (para-sulphophenyl)-5- pyrazolone-3-carbonic acid-ethyl ester in a two layer element consisting of a blue sensitive layer and a green sensitive layer, the former layer being exposed to blue light and developed to yellow as in Specification 459,665. The green sensitive layer is developed to purple with diethyl-para-phenylenediamine and an isooxazolone. The red-sensitive single layer of the bi-pack is developed to a negative or by reversal to a positive, and either in black and white or in colour. The black and white developed image is toned or dyed in known manner. If one of the two superimposed layers is red-sensitive, it can be developed to blue green by using indoxyl or indoxyl derivatives. If the red-sensitive layer is alone on one side of the support, the blue green picture is produced by iron-blue toning. Specification 486,424 also is referred to.

Abstract: 202,974. Venditti, G. Aug. 26, 1922, [Convention date]. Addition to 185,401. Hand sewing-tools. - The pawl for locking the spiked supporting wheels against rotation while the needle makes its stroke as described in the parent Specification is released by a member on the needle-supporting arm itself and also has a third arm which effects the disconnection of the needle-operating disc from the flywheel. Arrangements are also provided for disengaging the needle from the fabric and for varying the length of stitch. The needle-carrying arm g is actuated through a pin and slot connection by a disc f locked by a pawl e<1> to rotate with a flywheel rotated in one direction by the movement of a lever b<2> acting through sector gears b<5>, b<6>, c and a pawl and ratchet-wheel on the shaft of the flywheel. The arm g carries a projection g<3> which at the forward end of the needle stroke engages an arm j<3> of a three armed pawl, another arm j of which engages a ratchet-wheel i<2> fast on the shaft of the spiked wheels i. A third arm j<4> carries a ramp j' which is moved into the path of the pawl c<1> to lift it from its locking engagement while a projection j<6> comes into the path of a stud f<3> on the disc f so as to stop it positively. When means are provided for lifting the needle from the work the pivot g<2> of the slotted needlearm g is mounted on a lever o constrained by a spring p to keep the needle arm in a withdrawn position as shown in Fig. 6. A cam q is operated by a finger-lever q<2> to move the lever o and arm q forward into operative position. When the needle is in withdrawn position the movement of the apparatus over the material is allowed owing to the lifting of the pawl j by the engagement with the pawl-arm j<4> of a finger 0<SP>3> on the lever o. Variation of the length of stitch is effected by the employment of a ratchet having half the number of notches of the ratchet i<2> and axially movable so that it mav mask alternate notches of the ratchet i<2>, thus doubling the period during which the spiker wheels i are locked. The material to be stitched is placed on a board supporting a piece of sheet metal covered by a layer of swan-skin and a piece of cloth.
