Title: Improvements relating to automatic gear changing mechanism
IPC: F16H61/02
Filed: 1934-07-27
Abstract: 441,291. Variable speed gearing. ECCLES, W., 15, High Lane, Chorlton-cum- Hardy, FLURSCHEIM, C. H., Rushmoor, Fleet, Hampshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. July 27, 1934, No. 22043. [Class 80 (ii)] [See also Group XXXI] Relates to automatically actuated gearchanging mechanism for automobiles controlled by a governor responsive to the speed either of the vehicle itself or of the engine, and more particularly to the mechanism described in Specification 432,981 wherein the gear changing is modified in accordance with throttle opening. According to the invention a connection is provided between the road brake control of the vehicle and the governor such that application of the road brakes varies the biassing of the governor so as to cause it to tend to introduce a lower gear, thus assisting the braking of the vehicle by the engine. The brake lever a acts through a pivoted arm b upon an arm c mounted on a shaft 49, which is indicated by the same reference numeral in Fig. 2 of Specification 432,981, and is the shaft which controls the leak from the liquid governor system and the change of gears. The arm b is connected by link d to a dashpot piston e, whereby release of the brake is immediate, but the action upon the governor is prolonged, thus preventing a change of gear occurring before the driver has had time to accelerate. The mechanism could be applied to the biassing of the spring of a centrifugal governor where such is employed. The Provisional Specification refers to Specification 419,906.

Abstract: 930,596. Grinding wheels. NORTON GRINDING WHEEL CO. Ltd. May 1, 1962 [June 19, 1961], No. 22067/61. Class 60. A grinding wheel, particularly for removing burrs from machined gears, has a continuous thread on the periphery thereof and a flame sprayed coating of an abrasive metal oxide such as alumina on said thread which forms the grinding surface. A metal disc, e.g. of mild steel, is provided with a continuous thread form of the desired pitch on the periphery. The container of the thread form is machined to allow for a coating of flame-sprayed oxide to be applied to the desired thickness, e.g. 0.020 inch. Preferably the periphery of the disc is preliminarily roughened by shot or abrasive blasting. A preliminary layer of flame-sprayed metal, e.g. nickel chrome or mild steel, may be applied to improve the mechanical adhesive of the oxide layer. The abrasive coating may be treated with a cold setting or thermosetting synthetic resin in order to increase the resistance to wear of the wheel. Epoxy resin may be used. Specification 745,257 is referred to.

Title: Improvements in and relating to pressure measuring devices for thrust blocks
IPC: G01L5/12
Filed: 1933-08-09
Abstract: 408,854. Dynamometers. DEUTSCHE WERFT AKT.-GES., Postfach 889, Hamburg, Germany. Aug. 9, 1933, No. 22297. Convention date, Aug. 10, 1932. [Class 106 (ii).] In apparatus for measuring the axial thrust of single thrust blocks, the measuring devices, manometer, and charging device are all mounted on a non-rotary thrust member, and are connected in a closed pressure system, each measuring device comprising a cylinder the piston in which is moved by a fluid-operated diaphragm to take up its share of the axial thrust, and a protective diaphragm for closing the cylinder. The thrust of the collar on the shaft is taken by a non-rotary horse-shoe collar s. Three measuring devices are arranged in the collar concentrically of the shaft and connected together and to a manometer by the pipe b in a closed pressure system. A charging device is provided for supplying the system with pressure fluid, for instance, glycerine. Fig. 3 shows the construction of each measuring device. A diaphragm e of rubber is held clamped in a housing g by means of a ring f. Housing and ring form a cylinder in which slides a piston k having a projecting pressure head r. The cylinder is closed by a protecting diaphragm i. When the system is not charged the head r lies inside the surface of the collar s. The pipe b communicates with a gauge and screw pump. To charge the device, the inlet valve to pressure supply is opened and the pump piston screwed back to fill the pump cylinder. This valve is now closed and a pressure valve opened to the device whereupon the return of the piston will charge the system with fluid to distend the diaphragm e. until the heads r of the pistons k project beyond the surface of the collar s until they make contact with a stationary part of the block and take up axial thrust of the block. The pressure on the heads will be indicated by the gauge. To render the device inoperative, both pump valves are opened together.

Title: Improvements in and relating to the heat-treatment of metal objects
Inventor: WILSON ERIC JOHN RYMER
IPC: C21D1/70
Filed: 1958-07-11
Abstract: A method of treating metal objects to prevent distortion during heat treatment comprises in vesting the objects in a slurry of cement-like refractory material which is allowed to harden in situ to form a rigid coating round the object.  The object or a number of objects, may be placed in a metal tray or mesh basket enclosed in a bag of impermeable material, e.g. polythene, and a slurry of 30% plaster of Paris and 70% silica powder poured in and allowed to set.  The tray or mesh basket with the objects embedded in the refractory may then be heated and quenched.  The quenching causes at least a part of the investment to be broken away and the objects may then be cleaned.

The spheroidizing anneal comprises heating the forgings in nitrogen just below the austenite forming temperature at 1380‹ F. for 3 hrs., after which the temperature is raised above the austenite forming temperature to 1420‹ F. so that austenite coexists with carbides. After 3 hrs. the temperature is lowered to 1380‹ F. and after annealing times of 3 hrs. the temperature is lowered in 20‹ F. intervals down to 1260‹ F. The carbon is thereby precipitated on the existing undissolved carbides. The tempering temperature may be 250-400‹ F.

Abstract: 500,978. Television. FERNSEH AKT.- GES. Aug. 20, 1937, No. 22868. Convention date, Aug. 20, 1936. Drawings to Specification. [Class 40 (iii)] In a television apparatus of the type in which the electron image produced by focusing the scene to be transmitted on to a photoelectric screen and focusing the electron image thus produced on to an electrode over which the image is deflected, means are provided for reducing the deflection, so as to transmit a portion of the screen on an enlarged scale. This may be effected by reducing the deflecting field or increasing the accelerating field, or by altering the position of the deflecting or accelerating fields. In another method the object and image distance of an electrostatic electron lens may be interchanged by interchanging the position of two electrodes. Again the focusing field, particularly an electromagnetic focusing field, may be increased so that the second image instead of the first is formed in the plane of the scanning electrode. Steady deflecting fields may be applied to vary the portion of the scene transmitted. The effective size of the scanning aperture may be altered as described in Specification 499,661, or the aperture of an iris diaphragm in the optical system varied in accordance with the size of the portion of the image scanned. An optical view finder may also be varied in the same way.
