Patent GB-764171-A (GB)
Title: Improvements in or relating to surface treating apparatus
IPC: B24C3/06
Filed: 1955-02-23
Abstract: <PICT:0764171/III/1> <PICT:0764171/III/2> In a surface coating apparatus, a jet of coating material is directed at a surface to be coated by a blast gun to which the material is fed by suction in a material supply conduit leading to the gun, and additional suction means are provided to reverse the flow of coating material in the conduit when the suction feeding the material to the gun is cut off. The mobile apparatus comprises a source of compressed air 14.  The air passes through a valve V and aridifier 18 to pipes 21, 22.  The pipe 22 leads to a valve G, controlling the supply to a gap 62 between a material supply jet 60 and an outer tube 61 whereby the coating material is drawn through the jet towards the surface to be coated.  Coating material is supplied to the jet 60 from a pipe B having a T connection 90 with an orifice 85 connected to a suction pipe F and a coating material supply chamber 30.  A pipe E conveys coating material from the surface treated to a reclaimer R. Compressed air passes along the pipe 21 to an ejector P.  Suction at the orifice 23 draws any dust from a cyclone S connected to the reclaimer.  The reclaimer has a passage between members 33 and 41 and a screen 42.  The coating material passes into a chamber 31 from the pipe E, the chamber having baffles 34, the material falls on to the member 33.  The compressed air passes to a chamber 35 and then to chamber 38 the outlet from which flows air across the flow of material whereby heavy particles fall on to a screen 42 and descend to a chamber 30 (coarser particles being retained by the screen) fine particles are blown into a space between members 41, 33 and up passage 48 to the cyclone S.  Particles collect at the base 29 of the cyclone and can be removed, the residue being either evacuated to the air or a dust bag is attached to the ejector P to remove the remaining particles.  To adjust the air velocity in the passage between members 33 and 41 for particles of various densities the member 41 is adjustably mounted.  The orifice is also changeable to obtain the correct flow of material in the tube B.  The gap 62 is also adjustable by screwing the jet to obtain the required force of material.  In operation, the valve V is first opened and the air cycles through the tube F and reclaimer.  When the valve G is opened, suction at the jet 60 causes material to be impelled down the pipe B through the shell 72 to impinge with great force on the surface. Surplus coating material passes up the pipe E to the reclaimer R drawing in air through an air permeable skirt 63 contacting the surface.  On closing the valve G the suction in the line F draws coating material from the tube B into the reclaimer and when the pipe B is cleared, the material continues to cycle until either the ejector pump P is shut down or the valve G is opened and coating is resumed.  The apparatus can be used without the reclaimer and cyclone.

Title: Improvements in electric high-frequency vibrator
IPC: H01H50/76
Filed: 1946-02-21
Abstract: 632,642. Electromagnetic interrupters. PLESSEY CO., Ltd. Feb. 21, 1946, No. 5475. Convention date, Feb. 22, 1945. [Class 38 (v)] A vibrating armature 35 secured in a stack 12 passes through a driver coil 29 supported on an iron bracket 31 attached to an iron frame 10. The free end of the armature 35 co-operates with the end 11 of the frame 10 which forms a pole-piece of the magnet system. The armature carries two moving interrupter contact arms 36, 39 and two moving rectifier contact arms 37, 38, all of which engage stationary contacts supported in the stack 12. The two stationary contacts on each side of the armature are insulated from one another and situated side-by-side, being shaped as shown at 24 in Figs. 2 and 5 to enable them to be secured to the single bolt which holds the stack together. In order to avoid the use of heavy contact pieces on the moving arms the connections are so made that current always passes from the fixed contacts to the moving contacts as metal tends to be transferred from the positive to negative contacts. Heavy contact pieces are therefore used on the stationary contact arms, the moving arms being provided with a thin layer of contact metal by spraying or other means. The moving arms may for example consist of spring steel. coated with silver or platinum, the fixed contacts being of silver alloy or discs of tungsten. Only the interrupter contacts need be made in this way as the rectifier contacts are alternatively positive and negative and no transfer of metal takes place. Fig. 4 shows a modification of the moving contact arms in which free oscillations of the arms are damped. A phosphor bronze or beryllium copper spring 52 carrying a thin layer of contact metal 53 is engaged by a steel spring 51, the two springs being separated at their lower ends. When the springs are in vibration the friction between their upper engaging ends tends to damp free oscillations. Specification 594,862 is referred to.
