IPC: B01J19/18
Filed: 1969-01-29
Abstract: 1,235,981. Alkyltrihalosilanes. DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT. 29 Jan., 1969 [9 Feb., 1968], No. 4881/69. Heading C3S. Alkyltrihalosilanes are prepared by passing a gaseous olefin and a trihalo hydrogeno silane into a boiling mixture of the alkyltrihalosilane to be prepared and a platinum catalyst at a temperature of 30 to 150 C. and a pressure not substantially above atmospheric. The reaction may be continuous and an apparatus is described in which the reactants are introduced at the base of a column containing the boiling mixture and the reaction product is removed at the top and unreacted starting materials are recycled. The initial mixture is obtained by refluxing trihalohydrosilane, olefin and catalyst, the delivery of reactants beginning when the temperature approaches the boiling point of the reaction product. The catalyst may be platinum metal or compound, e.g. H 2 PtCl 6 , or those described in Specification 1,158,510. Propyl and butyl trichlorosilanes are prepared in the examples.

Abstract: 415,458. Barometric altimeter. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Feb. 24, 1933, No. 5680. Convention date, Feb. 25, 1932. [Classes 106 (ii) and 106 (iv).] An indicating-instrument is provided with means for setting it to indicate under a different condition and to indicate, independently of the indicating action, the condition for which it has been set. As applied to an aircraft-navigating instrument such as an altimeter the aneroid capsules 7, 8 are carried by a supporting member 9 and the movement in response to pressure variations is transmitted through a temperature compensating element and link 10 to a rock shaft 15. The capsules are also connected by links to a pivoted counterweight and spring to balance the system in order to prevent movement due to vibration, acceleration forces &c. The movement of the rockshaft 15 is transmitted to a countershaft 39 by gear sector 37 and pinion 38 and hence by gears 41, 42 to a hollow shaft 43 at the end of which is secured a large pointer 44 moving over a dial 45 having a scale marked in hundreds of feet. A concentric scale is provided marked in thousands of feet and co-operating therewith is a small pointer 47 driven by gears 48, 49 and a shaft 50 passing through the shaft 43. The capsules 7, 8 are carried by a screwed stem 9 which is prevented from rotation by a stop 65 sliding in a hole 67 but which may be moved axially together with the capsules by turning a nut 63 mounted for rotation without axial movement. The nut has secured to it a worm gear 62 operated by a worm on a shaft 57 which may be turned through gears 53, 54, 55 operated by a turn button 60. The shaft 57 is extended and actuates a Veeder counter 68 through bevel gear 71, 72. In use, before a flight the altimeter is adjusted to read zero at the height of the ground at which it is intended to land. To do this the knob 60 is turned so that the device reads, say 4000 ft. which is the height of the landing ground, this being registered on the counter. On approaching the landing ground the aviator will know exactly at what height above the landing ground he is flying.

Title: Salts of thiodiglycolic acid and their preparation
Filed: 1958-02-21
Abstract: The invention comprises cadmium thiodiglycolate and stannic thiodiglycolate.

An oil level dipstick having a closure body 20 for closing the oil filler pipe of an internal combustion engine comprises a resilient, compressible plug 23, upper and lower compression plates 27 and 26 respectively and a rotatable rod 22 to which the dipstick 21 is attached. The rod 22 is secured to a knob 31 and is located in a bore 24 in the plug. The plate 26 is secured to the plug 23 by tongues 52 and has a screw threaded sleeve 28 so that rotation of the knob 31 cause the plate 26 to compress the plug, sealing ribs 25 on the plug engaging the inner wall of the filler pipe. A weld 34 secures the dipstick to the rod 22 which is crimped at 33 to prevent downward movement of the plate 26. A longitudinal groove is provided in the closure body 20 to vent the engine crankcase. In a modification a screw threaded plug is secured to the bottom of the dipstick to receive a magnet for extracting bits of metal from the oil. Several modifications of the method of securing the dipstick to the closure body, including a flexible coupling, are described. Guide washers attached to the dipstick are also described.

Feb. 26, 1932, No. 5768. Convention date, Feb. 27, 1931. [Class 100 (iv).] In duplicating-arrangements comprising a number of ribbons carried by a pair of spools, means is provided for equalizing the tension on the ribbons, and thereby preventing formation of slack, during the winding movement. Means may also be provided for equalizing the unwound lengths of ribbon, and thereby taking up excessive slack, when the ribbons have been wound off either spool, the ribbons being connected together for movement relatively to this equalizing-means. In the arrangement shown in the Figure, an endless ribbon having the plies 22, 23 guided along the printing line is carried by spools 20, 21 provided with feed and reversal mechanism. The loops of the ribbon pass through openings in the spool-cores 51 and engage the spool-shafts 50. The means for equalizing tension during the winding movement consist of large studs 40 which are carried by pivoted arms 41 and are arranged between the plies. When the tensions are equal, the plies are equally diverted by the studs, but if either ply becomes slack, the other ply displaces the studs and the slack is taken up. If excessive slack forms, it is taken up by the pull of the ribbon when the ribbon has been wound off either spool, one of the loops running over the shaft of the empty spool. Specification 397,518 is referred to.

Abstract: 796,798. Grinding. CREEK, J. O. Feb. 24, 1956 [Feb. 24, 1955], No. 5822/56. Class 60. A device for removing burrs from the toothed edges 34 of a member such as a gas turbine part 32 comprises a movable worktable 13 and a member 49 which has the external contour of a spur gear and is arranged for its teeth to interengage with the teeth of the workpiece so that, upon movement of the workpiece, the spur gear rotates and an abrasive-carrying surface passes over the edges of the teeth 34. The de-burring action may be produced by an abrasive band 54 which acts upon the edges of the teeth 34 by its passage over a sprocket 49 arranged so that its teeth 55 extend into the slots 33 between the teeth 34 and cause rotation of the sprocket when the workpiece is rotated. Alternatively, instead of the abrasive band, the sprocket may have abrasive-surfaced teeth or be formed of rubber &c. which is either impregnated with an abrasive or used with an abrasive paste. As shown, three abrasive units 36A, 36B, 36C are arranged to operate, respectively, upon the two transverse edges, two vertical outer edges, and two vertical inner edges of the teeth 34. Each unit consists of a plate 39 adjustably carried on a post 35 and mounting four pulleys 47, 48, 50, 51 and the sprocket 49 for the passage of the abrasive band 54 ; the pulley 48 is outwardly spring urged to tension the band. The table 13 is mounted on a shaft 14 carrying a verticallyadjustable disc 17 by which it is driven by a motor driven friction disc 28 engaging the edge of the disc 17 ; vertical adjustment of the disc 17 by means of a screw-threaded shaft 21 engaging a yoke 18 carrying the disc varies the point of contact of the latter with the disc 28 and therefore the speed, and direction of rotation, of the table.
