Abstract: 360,240. Endless belt conveyers. PURVIS, G. A. E., Waterville, Strawberry Vale, Twickenham, Middlesex. Dec. 11, 1930, No. 37391. [Class 78 (i).] Relates to an endless conveyer for letters and other flat articles of the kind provided with one or more gripping devices the members of which are moved apart by stationary cam means against the action of spring means to receive from a holder an article to be transmitted, the said members then being released and caused by the spring means to hold the article which is then transmitted by the conveyer to a delivery position in which the members of the gripping device are again moved apart by cam means to release the article. According to the invention the gripping device comprises two spring-controlled members adapted to be moved away from and towards each other-in a rectilinear direction to receive, hold and release an article bv two rollers which are moved away from each other in a rectilinear direction and afterwards released by stationary cam means. The conveyer band a, Fig. 1, passing round sheaves b, c, is provided with three gripping devices and is driven by a motor i connected by a belt k to a pulley s which drives the sheave c through a belt r. Each gripping device comprises a pair of rollers 1, 2, Fig. 3, on pins 3, 4, secured to plates 5, 6 respectively. The plates are connected by springs 8 and slide horizontally in a casing 7 fixed to the band a. Rollers 11, 12, on pins 9, 10, secured to plates 5, 6, co-operate with stationary cams 13, having tapered faces 13a, at the required time to move the rollers 1, 2, apart. When a gripping device is moving in a clockwise direction round the sheave c, its rollers 1, 2, are moved apart by the cam 13 at A and are held apart by the flanges of the sheave c until they come opposite an article x supported in a holder 21. This holder comprises two metal strips 15, 16, Fig. 5, supported on pins 15a, 16a, in brackets 17, 18, and pressed together by springs 19, 20. The rollers 11, 12, now run off the tapered surfaces of the cam 13 at'x permitting the rollers 1, 2 to move towards one another and grip the article which is then carried upwards and forced between the strips 15, 16 of the holder at C. The rollers 1, 2 are now moved apart by the cam 13 at C and the article is left in the holder to be removed by hand.

Title: Formation of coatings on ferrous metal substrates
Inventor: STURGEON GEORGE MCHARDY
IPC: C23C10/54
Filed: 1963-10-04
Abstract: A stainless steel coating is formed on a ferrous substrate by applying a coating of Ni powder to the substrate compacting the powder and finally diffusing Cr into the coating at a temperature high enough to allow interdiffusion of the Ni, Fe and Cr.  In a modification a coating of Ni and Cr powder may be applied, compacted and then heated to effect interdiffusion.  It is preferred to add Fe powder with the Ni powder, the mixture containing 10%-20% Ni and the powder being applied dry or wet, as a paste or slurry from a metering device or by electrostatic or electrophonetic deposition.  The coating is compacted by rolling and is sintered at 750 DEG C. in hydrogen or cracked ammonia prior to chromising.  The chromising process is the conventional halide pack or gas process at 800 DEG -1400 DEG C.  In addition to Cr, Fe may also be deposited by using Fe/Cr in the diffusing pack. In the modified process a powder coating of a Fe/Ni alloy and Cr powder is preferred and after compacting, diffusion is effected at 1000 DEG C. for 6 hours in hydrogen or cracked ammonia.  The metal powders should have a particle size of 5-100 microns and the ferrous substrate a maximum C content of 0.15%. The chromising inter-diffusion step is preferably carried out using H.F. heating which causes less grain growth.  The final coating has a thickness of 0.001 inch -0.004 inch.

[Also in Group XXVI] A turbine driving a variable-pitch propeller has a brake associated with the turbine shaft and an electromagnetic clutch for engaging and disengaging the brake operated by means dependent upon variations in the number of revolutions or in the turbine load. A fluid-filled hydraulic brake 11 is connected to the shaft of the turbine 3 through an electromagnetic clutch 12 engaged and disengaged by a contactor 13. The contactor 13 is operated by a switch 18 controlled by a torque meter 19. The torque meter 19 comprises a U-shaped iron core magnetized by an alternating current, the poles of which are located a few millimetres away from the surface of the turbine shaft. At right angles to this core and combining to form a measuring head is a similar U-shaped iron core which is also equipped with a winding. A variation in the load or stress condition of the shaft affects the balance between the two fluxes produced by the two magnets thereby deviating the direction of the combined fluxes, which deviations are utilized for measuring or actuating purposes. In a modification, the contactor 13 is actuated by a speed governor. The hydraulic brake may be replaced by an electromagnetic or electrodynamic brake.
