Title: Improved Machine for Grinding the Blades of Pocket and Pen Knives.
Inventor: PRIESTMAN EDMUND
IPC: B24B3/54
Filed: 1917-05-16
Abstract: 115,691. Priestman, E., and Smith, H. C. May 16, 1917. Disk and wheel apparatus.-In a machine for grinding the blades of pocket and pen knives, grinding-wheels A, working rim to rim, are mounted in headstocks C adjustable on slides D, which are pivoted at E on the top of the pedestal S. The blade F is mounted in a rest G pivoted at P on a slide Q, which may be drawn outwards to enable the blade to be placed in the rest. The support for the slide Q is raised by a treadle J and rods H, I; the same movement is imparted by a rod L to a conical roller M, which works between friction rollers N on the slides D, whereby, as the blade is pushed upwards between the wheels, these are caused to swing apart about the pivots E in opposition to the pull of the spring 0; their rims then become inclined to each other and the blade is ground thinner at the point than at the shoulders. To grind the curved edge at the point of the blade, the tail of the rest G is tilted downwards about its pivot P. When it is desired to grind each side of the blade separately, one grinding-wheel only is used, and the blade is fastened in a holder having a slight rocking movement about an horizontal axis, so that the sides may be ground flat or convex.

The casing 1 carries end plates 2, Fig. 5, one of which is integral and the other threaded or both may thread into the casing, and each plate 2 has a threaded extension 3 receiving a cap 19 engaging a cover plate 18 to adjustably secure the casing in position. The spindle 13 is extended at 15 and threaded for the handle 16. A second latch may be combined with the same cover plates, the lower latch being key-operated on one side, the key rotating a disc carrying a cam 17.

Abstract: 1418807 Making extrusion dies SWISS ALUMINIUM Ltd 13 Feb 1973 [14 Feb 1972] 7032/73 Heading B3A [Also in Division C7] A method of increasing the wear resistance of the working surface of an extrusion die includes hardening the working surface by forming on it a layer of diffusion products of one or more hardening agents and the material of the die, on which layer is deposited a coating comprising a binder together with metallic material and/or solid lubricants. The diffusion products are formed by nitriding and boriding and these processes may be performed either simultaneously or successively. Prior to coating, the hardened surface is cleaned, degreased, polished and honed and the coating is applied in paste form together with an inorganic binder. The binder is cured either by heating the die or allowing it to cure at room temperature for several days. One or more metallic materials may be applied and the solid lubricant may be either graphite or molybdenum disulphide.

Filed: 1927-03-15
Abstract: 267,568. Dubilier Condenser Co. (1925), Ltd., (Assignees of Nyman, A.). March 15, 1926, [Convention date]. Condensers have the ends of the conductive elements 2, 3 projecting from adjacent sides of the stack, and a clamp consisting of a pair of bars 4, which may be of steel, is secured by loops 5 of wire or by bolts and nuts or the like.

Abstract: 589,637. Carburetters. BENDIX AVIATION CORPORATION. March 23, 1945, No. 7438. Convention date, March 23, 1944. [Class 7 (iii)] A carburetter is fitted with an unbalanced choke valve 7 which tends to be opened by atmospheric pressure and is normally biassed to a closed position which is varied according to ambient air temperature by a thermosensitive device, another thermosensitive device being provided to limit the valve opening due to engine suction during the warming-up period. A quadrant 9, Fig. 2, is fixed on the valve spindle 8 and is provided with a slot 17 engaged by a pin 16 projecting from an arm 12 loosely mounted on the spindle and connected to the quadrant by a spring 18. The choke is controlled during running by a thermally sensitive coil 24 mounted on the exhaust manifold and connected to the arm 12 by a link 26, and the extent to which the valve is closed is determined by a bimetallic strip 31 having an adjustable stop 33 which engages one of a series of teeth 30 in the arm 12. When the engine starts the increase of suction opens the valve 7 to an extent determined by the engagement of a stop 37 carried by a bimetallic element 34 mounted on the arm 12 with one of a series of teeth 38 on the quadrant. The Specification as open to inspection under Sect. 91 includes also a modification wherein the choke valve is symmetrically mounted on its shaft and carries a poppet valve which opens when the engine starts against the action of a spring which is loaded by a bimetallic element. In another modification a balanced choke valve 51, Fig. 6 (Cancelled) has a triangular opening 54 covered by a damper 55 controlled by a thermosensitive element 56. This subjectmatter does not appear in the Specification as accepted.
