Abstract: 601,617. Trueing grinding wheels. NORTON CO. Aug. 1, 1945, No. 19818. Convention date, Dec. 28, 1944. [Class 60] Trueing apparatus for a grinding-machine includes a pivotally-mounted frame arranged to swing in a circular path, a pivotally mounted housing on said frame, a trueing tool slide slidably supported on said housing, and means including a cam and follower mechanism, to move said slide relative to the housing and frame and to swing said housing as the frame is swung about its pivot to cause the trueing tool to true a predetermined shape on the grinding-wheel while maintaining the axis of the trueing tool in a predetermined relationship with the face being trued. On a vertical shaft 17, journalled in arms 11a, 11b of a bracket 11 fixed to a grinding-machine footstock 10, is pivoted a frame 14 guided in its circular pivoting movement by an arcuate shoe 18 sliding on an internal cylindrical surface 19 on the footstock 10. In the frame 14 is piyotally mounted at 60, 61 a casing 39 in which, on adjustable bearings, slides, without rotating, a spring-pressed slide 30 having an arm 31 carrying an adjustable diamond tool 32 for trueing a grinding-wheel 23. This slide 30 is constrained to move the diamond in the required path, and the casing 39 is pivoted to keep the diamond axis normal to the grinding- wheel face as the frame 14 is swung about its pivot 17, by means of a pair of spaced, adjustable, staggered followers 63, 64 formed on a downward extension 62 of the slide 30 which engage upper and lower suitably shaped cam faces 65, 66 respectively. Each cam face is preferably formed in two overlapping halves which are adjustable towards or away from each other by screw means 70 ; thus, in the extreme positions when it is desired to true the side faces of the grinding-wheel, the position of the tool may be adjusted accordingly. A gauge block 80 is provided to position the tool accurately relative to the pivot.

Abstract: 834,484. Batch mixing-machines. POURE, E. E. June 24, 1957 [June 26, 1956], No. 19845/57. Class 86 A mixing apparatus Figs. 1 and 2, comprises a tank 1 formed of lower and upper parts 2, 3, end walls 15 and a cover 4, the tank being supported by crossstays 12, 13 from two circular end-plates 9, 10 rotatable on fixed sets of rollers 11. Rotatable in the bottom 5 cf the tank is a pair of helixes 6 whilst a pair of helixes 8 is rotatable in the top 7 of the tank. The shafts 14 of the helixes pass through packing glands 16 in the end walls 15, the glands being made in halves, as described with reference to Fig. 3 (not shown), in order to facilitate their assembly or removal. The lower pair of helixes 6 are rotatable by a separate motor through a belt and pulley 37 on a shaft 32 coaxial with the plates 9, 10, the cross stays 12 and the longitudinal central axis of the tank. A pinion 31 on the shaft 32 driving a gear 29 on one shaft 14 the pinion 31 driving the other shaft 14 of the pair through an idler gear at a higher speed. Similarly the upper pair of helixes 8 are driven from a separate motor through a belt and pulley 38 on a shaft 33 coaxial with the shaft 32. The idler wheel 34 is shown in this instance and is mounted on a shaft 39 carried by the end plate 10. If desired the tank 1 may be rotated at the same time as one or both pairs of helixes. Owing to the separate drives of different speeds for the pairs of helixes the apparatus can be used for two stage and/or two speed mixing. For example for one stage of mixing the lower pair of helixes 6 is used. When the drive is stopped the tank is rotated through 180 degrees and the drive for the pair of helixes 8 is started. If desired only a single upper helix may be provided symmetrically above the bottom pair of helixes and the top part 3 and lower 4 modified accordingly. The driving motors may be mounted on the end plates 9, 10, or there may be a single driving source driving the pairs of helixes through clutches. In the case of separate driving motors these may rotate at different speeds or they may transmit their drives through reduction gearing of different ratios.

Filed: 1938-07-05
Abstract: 520,526. Vapour engines power plant. TAILLEFERRE, H. July 5, 1938, No. 19854. [Class 122 (iii)] A power plant for submarines, torpedoes &c. is operated by liquefied or solidified gas raised in temperature by exothermic reactions involving the medium in which the apparatus moves the exhaust being soluble in said medium, thereby not revealing its presence. As shown in Fig. 1, a reservoir A contains liquefied ammonia and a heating-coil B. An engine M is supplied from the dome F. The engine exhaust passes from a pipe R into an absorber-heater O. The liquid in which the vessel moves, e.g. sea water is introduced into the tank O by a floatcontrolled valve. The hot solution of ammonia is driven by the pump V through the coil B which exhausts to the sea. In the construction shown in Fig. 2, the reservoir has two heating- coils B, C. A tube D surrounds the end of a pipe E. A reservoir of sulphuric anhydride G with an air chamber H at the top is arranged as shown. An engine I actuates pumps J<1>-J<3>. A mixer K and a superheater L are shown between pumps J\ J<2>. The pump J<1> draws sulphuric anhydride from the tank G and passes it into the mixer K where it unites with water from the reservoir O supplied by pump J<2>. The generated heat superheats the ammonia driven through the boiler L by the pump J<3>. The ammonia passing to the engine M entrains in an injector P the exhaust of the engine I thereby reducing its back pressure. Liquid is introduced into the base of the reservoir A in equal volume to that removed to maintain the balance of the machine. The excess water in the reservoir O and the hot solution of ammonium sulphate from the superheater L are used in the coils B, C.
