Abstract: 146,479. Krupp Akt.-Ges., F. July 8, 1916, [Convention date]. Discharging by means external to breech mechanism.-Relates to means situated at a distant transmitting-station for obtaining the advance in ignition of gyroscopically-controlled electric firing-gear to suit the firing delay which occurs when the ship rolls. According to the invention, the sighting-telescope B<2>, stabilized on a trainable support A by a gyroscope B, carries on an arm B<1> a mark b<5> and a contact b<6>. Further, a mark e<1> and a contact c<1>, preferably carried by movable sectors E, C, are connected through gearing to a lever D for setting the mark e<1> to the maximum outward swing of the mark b<5>. When this has been done, the lever D is secured and the contact c<1> is then correctly set relatively to the contact b<6> to give the desired advance ignition. The contacts b<6>, c<1> are included in a firing-circuit passing through a coil g<1> on the gun breech and controlled by a switch F. The elevation for range is set up at the transmitting-station on a drum h<3> and communicated to dials H' at the gun or to the gun itself. A tell-tale indicator J<1> shows at the transmitting station when the gun has been properly elevated to accord with the setting on the drum h<3>. The heeling angle of the ship is read off on a scale a' 'by an index b<4> and applied to the drum H<2> to correct the gun elevation. Specification 30292/10 is referred to.

In an electrophonic musical instrument twelve cylinders 1, 2, ... 12 are coaxially mounted and rotate together at the same angular velocity. Each cylinder carries endless magnetic records of a fundamental frequency and one or more of its harmonics, preferably including octaves, the fundamental frequencies of two adjacent cylinders being a semitone apart. The cylinders have differing diameters so that each record contains an integral number of oscillations. On each cylinder the various sound tracks may lie side by side, Fig. 1, or be superimposed at varying angles, Fig. 2 (not shown), as described in Specification 683,090. Each sound track has an associated magnetic reproducing head 13 which may be of such a width and movable laterally, Fig. 1, or angularly, Fig. 2 (not shown), in such a way that it may cover two or more tracks simultaneously. In the case of superimposed sound tracks, a single rotatable reproducing head may be used. In modifications, the cylinders 1-12 may be replaced by discs or tapes. The output circuits may include means for producing transients. The instrument may be played by means of a keyboard, with stops for tone control, volume being controlled either by pedals or by the variation of pressure on the keyboard which in this case is pivoted and coupled to a variable resistance. One possible form of the instrument has two inclined surfaces, Fig. 3, one carrying the keyboard and the other carrying push buttons for stops or for bass notes as in an accordion. The instrument may have its own amplifier and loudspeaker or may be connected to a radio receiver.

Abstract: 1,029,652. Valves. BUTTERWORTH ENGINEERING CO. Ltd. May 25, 1962 [May 25, 1961; Jan. 25, 1962], Nos. 18853/61 and 2767/62. Heading F2V. [Also in Division F1] A gear pump has a passage 136 connecting the pressure and suction sides 102a, 102b respectively, a valve 127 for closing the passage, a spring 114 urging the valve to the open position, and means urging the valve to the closed position when the pump is operative comprising, as shown, a control rod 112 of greater area than the valve 127, so that a resultant force tending to close the valve is exerted by the pump delivery pressure. The valve is moved to the closed position manually by movement of the control rod 112 which extends out of the housing 109. A pressure relief valve is also provided and may comprise a spring-loaded plate in a bore inside the valve 127 (Fig. 2, not shown), or, as shown, the valve 127 is axially movable relative to the control rod 126, a piston 128 integral with the valve 127 sliding in a bore 124 and being integral with a rod 129, the valve then being biased to the closed position by a spring 131. The nut 132 retaining the spring 131 serves as a damper, to prevent oscillation of the pressure relief valve. The valve may be opened manually by first opening the pressure relief valve to relieve the differential pressure keeping it closed, and may be held open by the plunger 115c of a solenoid 115 engaging a groove 116 in the control rod. In another embodiment the pump has one or two pressure loaded end plates, the plate on one side, which may cover both gears (Figs. 13-15, not shown), or only one gear (Fig. 16, not shown), is fixed to the control rod to be moved axially to provide communication between the pressure and suction sides and a pressure relief valve is again formed in a bore in the control rod. The pump is connected to a reservoir by a tube 105 inside which is a further tube 107 through which oil returns to the reservoir when the valve 127 is open. The oil is thus cooled. The upper ends of the tubes 105, 107 are respectively inside and outside a filter in the reservoir. The pump is intended to be continuously driven by a motor vehicle engine and to be used for the intermittent operation of accessory equipment such as hydraulic jacks. The valve allows oil from such jacks to be returned to the reservoir.

IPC: F16D11/10
Filed: 1953-07-02
Abstract: 720,338. Shaft couplings. ROLLS-ROYCE, Ltd. July 2, 1953 [July 25, 1952], No. 18927/52. Class 80 (2) A shaft coupling, for connecting e.g. compressor and turbine shafts 10, 11 of a gas turbine, including spherical seating surfaces 15a, 19a accommodating slight malalignment and taking axial tension or compression due to gas loads on the coupled parts, comprises torque transmitting helical splines 14, 15 on the respective shafts which produce an axial component (arrows 16, 17) opposing the working axial load (arrows 12, 13) but differing therefrom by a predetermined amount which leaves a finite but reduced load on the spherical surfaces. The latter can thereby be reduced in size to such an extent that one coupling may be disposed concentrically within another for coupling different pairs of shafts, e.g. for connecting high and low pressure compressor-turbine shafts respectively, Fig. 4 (not shown). As shown the spherical surfaces 15a are formed on the interrupted ends of the helical splines 15 on the inner shaft 11 which are gapped to receive similar short helical splines 19 in a lock sleeve 18, carried by the shaft 10, the forward ends 19a of the splines 19 being also spherical to complement the surfaces 15a with which they are brought into butting relation by passing the splines 19 axially into the gap and there turning the lock sleeve 18 through half a spline-pitch. The sleeve is locked in this rotary position on the shaft 11 by a second shorter sleeve. 23 splined on the shaft and locked to 'the lock sleeve 18 by a spring-loaded peg 24, the sleeve 23 having a projection engaging a narrower portion 22 of stepped notch 21 in the lock sleeve 18. By releasing the peg 24 and withdrawing the short sleeve 23 axially into the wider step of the notch 21, the sleeve 18 can be turned to move the splines 19 out of butting relation, permitting axial separation of the coupled parts. The lock sleeve 18 is axially adjustable on the shaft 10 on a square-section screw-thread to permit relative axial adjustment of the coupled shafts. In Figs. and 3 (not shown) the shaft 11 with gapped internal splines is outside the shaft 10 and the lock sleeve 18 screws in an internal thread in the latter 10, being locked for rotation with the former 11 by an axially retractable internal sleeve having external splines engaging splines in the lock sleeve and in a collar fixed in the outer shaft 11 against the ends of its splines, by a screwed ring, the collar having frictional or splined engagement in the shaft.

Abstract: Metal anilides are formed by reacting anhydrus aniline with aluminium and one or more other metals or alloys at elevated temperatures, preferably in the presence of 0.01 to 1 per cent by weight of the metal, of a mercury catalyst, suitably mercuric chloride.  The reaction mixture may be boiled under reflux and hydrogen removed overhead.  Anilides produced with the aluminium anilide include those of magnesium, manganese, zinc, chromium and molybdenum.ALSO:Alumina-containing mixed metal oxide gels, the other oxide being magnesium, manganese, chromium, zinc or molybdenum, with silica as an optional additional oxide, are prepared by reacting aluminium and one or more other metals or alloys with anhydrous aniline at elevated temperature to form mixed metal anilides and hydrogen which is removed overhead and hydrolysing the anilides produced to form a hydrous mixed metal oxide complex which is dried to form a gel.  The hydrolysis may be effected with water, steam, silica hydrosol or hydrogel or with an impregnating solution of a metal salt such as ammonium molybdate or chromic acid at temperatures preferably between 212 and 400 DEG F.  The slurry obtained may be further impregnated.  According to an example equal parts of aluminium and magnesium were reacted with aniline in the presence of a mercuric chloride catalyst under reflux; on cooling the contents were poured into distilled water.  The aniline was removed and the mixed aluminium and magnesium hydroxide reaction product was freed from water by alcohol followed by ether extraction after which the gel was dried.  The gels may be employed as catalysts in hydrocarbon reforming and cracking.  Specification 719,723 is referred to.
