Title: Triorganosilyl compounds
IPC: C07F7/18
Filed: 1955-08-29
Abstract: The invention comprises triorganosilyl methyl isothiocyanates of the formula X3SiCH2NCS where X is a monovalent hydrocarbon or hydrocarbonoxy radical, the compounds being useful as fungicides. They may be prepared by reacting amines of the formula X3SiCH2NH2 with carbon disulphide in the presence of alcoholic alkali metal hydroxide to form a dithiocarbamate X3SiCH2NHCS2M, M being the metal, which is then treated with lead nitrate to form the lead salt, which is decomposed on heating to give the isothiocyanate. Alternatively the amine and CS2 are reacted with trimethylamine in benzene solution giving a compound of the formula X3SiCH2NHCS2HNMe3 which is reacted with ethyl chlorocarbonate to give the isothiocyanate. The radical X may be alkyl, alkenyl, cycloaliphatic, aryl or aralkyl or their oxy derivatives.  The examples describe the preparation of (1) trimethylsilylmethyl isothiocyanate; (2) triethoxysilylmethyl isothiocyanate; (3) octadecyl vinyl phenylsilyl methyl isothiocyanate; (4) dimethyl phenoxy silyl methyl isothiocyanate.  In (1), the sodium and lead salts of N-trimethyl silyl methyl dithiocarbamic acid are isolated as intermediates, and the final product is reacted with aniline to give N-phenyl-N1-(trimethylsilylmethyl) thiourea.

Abstract: 767,338. Aircraft air brakes. COMMONWEALTH OF AUSTRALIA. Aug. 26, 1954 [Sept. 7, 1953], No. 24883/54. Class 4. Drag producing means comprises a plurality of curved members arranged substantially parallel to each other and spaced at intervals so as to form passages between them so that fluid flowing relatively to a body to which the means is attached, is deflected through a considerable angle. The angle may be less than, equal to, or greater than a right angle, the former case being shown in Fig. 5, where a plurality of curved members 31 are mounted between parallel plates so that their leading portions are substantially parallel to the direction of undeflected flow, the whole forming an aircraft dive brake at the trailing edge of a wing section, the brake being movable to a position inside the wing section of comparatively low drag. In Fig. 11, two members 38 are movable from the position shown to one inside the wing. Alternatively, the members may be pivoted forwardly for movement from and to the drag producing position or may have a sliding movement. Some of the curved members 31 nearest to the wing may be removed, or replaced by a flat plate. In Fig. 18, a plan view is given of a plurality of members 31 upstanding from the trailing edge of a wing, and similarly disposed beneath, so as to deflect the air to a spanwise direction.

Filed: 1950-10-12
Abstract: 703,693. Springs. WILMOT-BREEDEN, Ltd. Aug. 22, 1951 [Oct. 12, 1950], No. 24912/50. Class 108(3) [Also in Groups XXIII and XXIV] A rotary mop or abrasive wheel b is pressed against a work-piece of varying contour by a torsion bar q, or other spring or weight means, acting through linkwork wherein an effective lever arm decreases as the means is stressed so that a constant working pressure is maintained as the mop rises and falls. The mop is carried by a bellcrank pivoted about a shaft f and having a roller, or a pair of rollers, i engaged by a lever j which is pivoted on trunnions m and is linked to an arm p on the torsion bar q. The plane of the surface engaging the roller i contains the axis of the trunnions m, and the mean position of the link o is at right angles to the lever j. The pivot pin s of the link o is carried by a block slidably adjusted in the lever j by a screw t. During adjustment the link o is locked to the arm p (e.g. by a removable pin x) so that the bar q is correspondingly, adjusted along a slot v in which it is mounted. The mop is driven by a belt from a pulley; Fig. 2 (not shown), on the shaft f. The invention is also applicable to grinding or cutting machines. Alternative spring or weight means may replace the bar q, and, according to the Provisional Specification, a curved rollerengaging surface may be employed, or the lever j may carry a roller engaging a flat or curved surface on the bell crank.

Title: Helicopters
IPC: B64C27/04
Filed: 1944-12-12
Abstract: 590,514. Helicopters. BENDIX, V. Dec. 12, 1944, No. 24919. Convention date, Nov. 23, 1943. [Class 4] A helicopter comprises two coaxial counterrotating rotors 27, 28, with non-articulated variable pitch wings, each of which is provided with a control blade member 70 Fig. 12, which is projected cyclically from the wing during a portion of its revolution to furnish a propulsive force. The rotors are mounted on shafts 42, 46, driven in opposite directions from two engines through shafts 23a, 24a and bevel gearing 36, 40, 41, Fig. 5a. Overrunning clutches are provided to enable the rotors to autorotate in the event of engine failure. The pitch of the lower rotor wings is varied by means of a sleeve 60, Fig. 5b, movable in the vertical direction by a sleeve 62, the member 60 being formed with inclined cam slots which are engaged by projections 56c, 56d at the roots of the blade spars 56. A similar member 61 attached to a sleeve 63 effects pitch variation of the upper rotor wings. Vertical movement of the sleeves 60, 61, for simultaneous pitch adjustment is controlled by one or more hand levers 105, Figs. 18. 25, which are connected to a vertically movable shaft 66 through links 107, 108, 109. Differential pitch variation for steering or turning the aircraft is obtained by rotation of the shaft 66 by pedals 145a, 145b, and 146a, 146b, connected by cables 149, 151, to a tiller 150, Fig. 18. The control blade members 70 are actuated by longitudinal movement of threaded shafts 73, Fig 12, effected by conical cam lobes 93a, 93b and 100a, 100b, Fig. 5b, which engage rollers 92 connected to the shafts 73 by links 90. The larger cams 93a, 100a are used for effecting forward movement and the smaller cams 93b, 100b for rearward movement of the aircraft. The degree to which the members 70 are projected from the rotor wings is controlled by vertical movement of sleeves 96, 101, effected by fore-and-aft movement of a universally mounted hand lever 115, Fig. 25, through links 126, 127, 128, 129, 130 and 132. Lateral movement of the lever 115 results in the cam lobes being moved vertically by equal amounts, thereby causing the members 70 to be projected to different extents from the upper and lower rotor wings to control movement of the aircraft in roll. To control pitching, the cam sleeves 96, 101 may be rotated to vary the sector of the circle of revolution during which the members 70 are projected from the rotor wings. A hand lever 140, Fig. 25, is provided for this purpose, sprocket chains 137, 139, operating worm gearing by means of which the sleeves 96, 101. are rotated in opposite directions.

Abstract: In a modification of the process of the parent Specification for the preparation of dialkyl sulphoxides by the oxidation of dialkyl sulphides with a solution of nitrogen dioxide, the resulting gases are recycled and the dialkyl sulphide vapour entrained with the circulating gases is oxidized by reaction with a solution of nitrogen dioxide in dialkyl sulphoxide to form the corresponding dialkyl sulphoxide, which is removed as such from the gases before they are admixed with a quantity of oxygen or an oxygen-containing gas at least that required to form nitrogen dioxide by oxidation.  The dialkyl sulphide contained in the liquid reaction product may be expelled into the recirculating gas by means of an inert gas. Dinitrogen trioxide formed in the treatment of the gases containing dialkyl sulphide and left in the nitrogen dioxide solution may be re-oxidized to nitrogen dioxide with oxygen.  The nitrogen dioxide solution may be increased in concentration by using it to wash the waste gases.  Oxygen may be fed to the primary reactor.
