Title: Improvements in or relating to apparatus for applying predetermined loads to objectsfor testing hardness and other purposes
Inventor: JONES JAMES THOMAS EYCOTT
IPC: G01N3/42
Filed: 1950-05-11
Abstract: 667,919. Testing physical qualities. VICKERS-ARMSTRONGS, Ltd. May 11, 1950, No. 11795/50. Class 106 (ii). [Also in Group XXIX] Apparatus for applying a predetermined load to a test-piece for hardness determination of the kind comprising a piston for applying pressure to a liquid and a second piston responsive to the liquid pressure for applying the load, with means for controlling the maximum pressure applied and its duration, is characterized in that a valve assembly is provided whereby one of a number of predetermined pressures may be preselected prior to a test. A body 1, fixed in relation to the test-piece, is provided with a reservoir 2 containing a piston 6. The piston carries a non-return valve 10 and is urged by means of springs 16, 17 towards the bottom of the reservoir as shown in Fig. 1. Movement of the lever 20 compresses the springs 16, 17 and withdraws the piston to the top of the reservoir, liquid passing freely through the valve 9, 10. When the lever 20 is released the piston is returned by the springs 16, 17 and compresses the liquid, causing it to flow through conduit 42 where a valve 43 is adjusted to control the rate of flow and hence the time of application of the pressure. The liquid passes into conduit 40 downwardly to the piston 51 in the chamber 41 and thereby applies pressure to the rod 54 carrying the indenter, and also upwardly to a spring-loaded relief valve 24 which is arranged to lift at a predetermined pressure and so limit the maximum load applied to the test-piece. In order to provide a number of predetermined pressures which may be preselected before a test, the valve is provided with three seats 31a, 31b, 31c (Fig. 3), one of which is brought into operational relationship with the valve tip 24a by rotation of the sleeve 31 by means of a suitable knob 35 secured to the sleeve 31 and retained by a screw 35a riding in a slot 34a in the stationary flange 33. A spring-loaded ball 36 co-operating with suitably-located indentations ensures correct positioning of the sleeve in one of the operational positions. Liquid passing the valve 24 is returned to the reservoir above the piston via conduit 38. At the end of its stroke the piston uncovers a port 45 which releases the pressure exerted by the piston 6, allowing the loading piston 51 to be returned upwards by the spring 52. A flexible bellows 55 is provided to minimize leakages of liquid from the body 1 and liquid inside the piston 51 is allowed free access to the reservoir via conduits 57, 58, 59, to minimize still further any leakage of liquid.

Abstract: A method of applying a coating of thermoplastic material to elongated articles wherein the plastic in powder form is fluidized within a chamber by passage through the powder mass of a current of gas is characterized in that the article in a heated condition is continuously drawn into the chamber, and through the mass of fluidized powder therein.  The term "elongated articles" includes articles having their longitudinal dimension greatly in excess of their cross-sectional dimensions such as wire, metal strip or wire mesh sheet.  The thermoplastic powder may be polythene.  Heating may be by means of a gas flame, a wire heating oven, constant electrodes, induction or infra-red means.  An example describes the coating of wire-mesh-netting with fluidized polythene powder.  At the point of entry into the coating chamber the path of the article may be in a horizontal direction and it may be passed out in a vertical direction through the top of the chamber.  The porous base supporting the fluidized powder mass or the chamber containing the game may be subjected to agitation. The gas stream by which the powder mass is fluidized may be caused to pulsate.  Means may be provided for removing any excess of powder adhering to the coating layer on leaving the chamber.  The coated article may be subjected to heat treatment to sinter the coating as leaving the chamber. Specifications 759,214, 834,284 and 852,638 are referred to.
