Vegetables such as bunches of radishes, onions, carrots, turnips &c. are washed in an open ended and slatted rotating drum 3 which is supported and rotated by means entirely external of the drum. The drum is partly immersed in the water level 4 in a tank 1, the vegetables being dropped from a shoot 11 into the drum, and drop from the other end on a conveyer 12 which carries them out to a delivery shoot 15. The shoot 15 may have alternative exits closable by a flap 17 while the other exit delivers into a bag placed at its mouth. The drum is mounted in a cage of rollers 5 and is driven by a belt 8 from a motor driven shaft 10 which also drives the conveyer 12. Rinsing liquid is supplied from a spray 19. The discharge end 3b of the drum may be partially closed by a hand adjusted shutter 20, Fig. 4, to regulate the size of the aperture 21 to suit the kind of vegetables being washed. Side plates 22 guide the vegetables on to the conveyer 12. A helical guide, e.g. pieces 30 of rubber tubing inside the drum may assist the feed of the vegetables through the drum.

Title: Working of high tensile sheet metal

Abstract: 612,280. Dimpling; punching. ENGINEERING & RESEARCH CORPORATION. May 23, 1946, No. 15595. Convention date. May 31, 1945. [Class 83 (iv)] A method of dimpling magnesium or other sheet metal which tends to crack when worked cold, consists in forcing a dimpling-tool against the metal with a pressure insufficient to dimple it while cold, maintaining such pressure and momentarily heating the metal at and adjacent the area of contact of the tool so that the pressure applied will effect the desired dimpling. High tensile sheets 30 are placed on a member 42 in electrical connection with a contact 44 and above an anvil 20 surrounding a punch 22. An upper dimpling die 2 connected to the other pole of a source of electrical energy is brought down on to the work and maintained at a given pressure until the heating effected by the flow of current softens the sheets in the area of the die which then descends on to the anvil causing the punching and dimpling of the sheets.

Title: Improvements in apparatus and process for treating diamonds by glow discharge
IPC: H01J37/34
Filed: 1965-04-13
Abstract: <PICT:1100560/C6-C7/1> A method of cleaning by glow discharge and coating by sputtering whereby diamonds are coated with Mo or Ti followed by Cu in an atmosphere of hydrogen and A, He or Kr.  The apparatus comprises a vacuum chamber 12 enclosing a bucket shaped cathode 11 containing diamonds to be coated, a movable sputtering cathode 17 of the same material, a second sputtering cathode (not shown) mounted on support 51 and an anode 16.  Cathode 11 contains a heating element flexibly connected to an A. C. supply by springs 31, 32 permitting the cathode to be rocked by a rotating electromagnet 47. Preliminary cleaning comprises heating the chamber with external infrared lamps 18, 19 and heating cathode 11 whilst evacuating the chamber and purging with hydrogen.  A voltage is then applied across the anode and cathodes 11, 17 in dotted position to effect glow discharge cleaning during which the cathode 11 is rocked to expose all the diamond surfaces and argon almost completely replaces hydrogen. Cathode 17 is swung beneath anode 16 and the potential of cathode 11 made continuously more positive than 17 causing sputtering to commence and increase and the glow discharge to continue but to decrease.  When sputtering starts the heater of cathode 11 is disconnected.  A second coating e.g. Cu may be deposited from the other sputtering cathode.  The diamonds may then be compressed and the Cu sintered or melted resulting in a compact of diamonds.  The method may be used to coat less than the entire surface.

Abstract: 332,338. Novak, I. J. May 21, 1929. Blocks and shoes.-Curved brake elements are produced by impregnating a flat blank of incombustible fibrous material with a saturant which becomes hard when heated, calendering the blank when the saturant has dried, and shaping it to a predetermined curvature and heating while it is positively held to this curvature under substantially no compression, whereby the saturant becomes hard and maintains the blank in its curved shape. The saturant may comprise phenolic resin of the infusible type and chinawood oil, or straight chinawood oil, or the liquid reaction product of cresylic acid, formaldehyde and ammonia, or the liquid reaction product'of phenol, formaldehyde and caustic soda. Short asbestos fibre is mixed with water, 5 per cent paper fibre, 2 per cent starch, and 10 per cent fine graphite. Sheets formed from this mixture are pressed with interleavings of burlap. After treatment with the saturant and drying, the sheets are given a short soaking in water to prevent sticking and then calendered to 0.0005 in. of the required thickness, die-pressed to size and laid in semi-circular forms and curved in ovens.

The male member 25 has a pin 26 formed with a spherical end-piece 27 of which the diameter is greater than the wall separation of the U of the female member, and which diameter is greater than that of the apertures 37. A connection between the members is therefore made by inserting the spherical end 27 into the U-shaped portion until the sphere surfaces engage the edges 36 of the apertures 37, thereby holding the members together (Fig. 6, not shown). Resilient projections 43 extending from the U-channel walls may be used to retain the connector in a body member. In an alternative form of female connector (Fig. 2, not shown) the aperture and slots are formed adjacent the top edge of the U-channel wall. Several such male, or female, connectors may be mounted in a single insulating body and the body may be formed by moulding it around the connectors (Figs 1-4, not shown).
