Abstract: 873,933. Cooling discharge apparatus. ASSOCIATED ELECTRICAL INDUSTRIESLtd. June 30, 1959 [July 28, 1958], No. 24243/58. Class 39(1). In an evaporative cooling system, for an electron tube in which at least the main anode 18b of the tube is immersed in a cooling liquid contained in a boiler, this boiler is constituted' by an insulating container 12 made of resinbonded fibre-glass material. The boiler may be made by applying successive layers of fibreglass, treated with an epoxy or other suitable' bonding resin, to a mandrel until the desired thickness has been reached, appropriate curing of the resin then being effected. If desired, one or more metallic strengthening members may be embedded in the boiler during the formation thereof, e.g. in the top cover, which may be formed with a central recessed portion 16 defining an aperture bounded by an annular ledge 17, the tube having a mounting flange 19 by which it is supported on the ledge. Two embodiments of the invention are described, the first (not shown) having a heat exchanger provided externally of the boiler and the second, operable at an internal pressure above atmospheric pressure,' having a cylindrical copper shield 21 surrounding the copper anode 18b, which is in turn surrounded by a tubular copper helix 22 forming an internal heat exchanger. The cover may be provided with a pressure actuated switch effective to disconnect the electrical supply if the internal pressure becomes too great, or a'valve safety switch of the kind described in Specification 809,170.

Title: Improvements in drying, heating or the like apparatus
IPC: D06C7/00
Filed: 1926-10-04
Abstract: 269,064. Wood, T. E., and Heymann, H. Oct. 4, 1926. Air, controlling circulation of; heating-fittings.-The materials, such as textiles &c., to be dried are conveyed on endless bands or otherwise through a chamber having zones maintained either at the same or different temperatures by independent currents of heated air which are admitted to the zones through concentric ducts. The chamber has drying-compartments 1, 2, 3 and a cooling-compartment 4. Cold air is drawn by a fan 5 through a valvecontrolled opening 20, upwardly through the cooling compartment, and into the perforated collecting-chamber 25, which extends throughout the length of the chamber, and thence through the valved-duct 21 to the fan which forces it, together with fresh air admitted through the valved-inlet 23 of the fan, through the heater 6, which may be of the kind described in Specification 230,612, [Class 64 (iii), Surface apparatus &c.]. From the heater, the air passes into concentric ducts 9, 10, 11 and thence through ducts 12, 13, 14 to the drying-compartments. The air then passes through the perforated floors of the compartments to the collecting-chamber 25 from which it exhausts through ducts 29 into a longitudinal flue 30 having an outlet 31 to the atmosphere. By closing the inlet openings 20, 23 and opening the dampers 27 in the collecting- chamber 25 and the opening 24 to the fan, the air may be continuously circulated. Further, the valves controlling the openings 20, 23 and the exhaust outlet 31 may be opened and closed intermittently.

Title: Device for use on sewing machines for the automatic production of ornamental stitching, sewing
IPC: D05B21/00
Filed: 1959-07-22
Abstract: 929,018. Sewing-machines. GEORG UTZ A.G. July 22, 1959 [July 23, 1958], No. 25076/59. Class 112. A sewing-machine attachment comprises a casing securable to the sewing-machine presser bar, an arm 9 engaging the needle carrier 14 on the needle bar to be oscillated thereby and turn step-by-step a shaft 6 pivoted in the casing. Rollers 24, 25 on a control slide 23 engage control cams 20A, 20B on the shaft 6 to reciprocate the slide as the shaft turns. A lever 27 pivoted to the casing at 28 carries at one end a foot 71, the other end being provided with a slide block 30 engaging a slide 26 disposed at one end of a shaft journalled in an eccentric bush 31 carried in the control slide 23. The angular position of the slide 26 can be varied by a knob 32 to vary the amplitude of the cross-wise oscillation of the foot 71 as the control slide 23 reciprocates. The bush may be rotated in the slide by a lever to vary the position of the centre of oscillation of the foot. The lever 9 is provided with a segment 66 and a slot 50 through which projects a lug of a balance member 48 freely pivoted on the shaft 6. The balance member is thus engaged and oscillated by the lever 9 as the needle bar reciprocates, and a bolt 51 (see Fig. 6) on the balance is embraced by the forked end of a lever 52 pivoted at 53 to one end of a lever 54 itself pivoted 60 to the casing. A slide block 56 carried on the lever 52 is engaged in a slide 57 pivoted to the casing. The angle of the slide is varied by a lever 63 to vary or reverse the movement given by the bolt 51 to the levers 52 and 54. A material feed bar 62 having at one end a feed foot 62<SP>1</SP> disposed in slots in the foot 71 is connected at its other end to the lever 54, so that the foot 62<SP>1</SP> may feed material as the balance 48 oscillates. To this end a pressure part 70 on one end of a lever 68 pivoted at 69 to the casing is periodically pressed down on to the foot as the segment 66 on the arm 9 engages a roller 67 on the other end of the lever 68. The Specification also describes (Figs. 16 to 20, not shown) other means by which cams can actuate the control slide, and (Fig. 21, not shown) an arrangement in which a cam replaces the balance 48. Fig. 22 (not shown) shows how a set of cams may be releasably fastened to the shaft 6.

Abstract: 744,602. Soil-stabilising apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 6, 1954 [Oct. 9, 1952], No. 25355/52. Class 68(1) [Also in Group XXX] In a soil - stabilizing apparatus cement is delivered from a hopper 28a to a screw conveyer 27 extending through a fixed axle 6, which is adjustably supported from a vehicle chassis and about which rotates an excavating rotor 5, to a hopper 28b. Cement discharges from the hub 6 through a slot 29 extending throughout the length thereof into the chambers 32 of a rotor 31 of a metering means. The speed of rotation of the rotor 31 and thence the rate of discharge of cement is related to the speed of rotation of the rotor 5 through suitable gearing, and the cement from the metering means is discharged through an adjustable nozzle 30 on to the soil, which is broken up and carried forwardly and then rearwardly over the rotor 5. Cement in excess of metered requirements is delivered by the conveyer 27 to the hopper 28b. In another construction of apparatus the cement delivery equipment is omitted. The rotor 5 consists of a number of blades 12 extending between aligned slots formed in the peripheries of discs 10 disposed along the axle 6.

A sheave J is mounted on each side of the nut D, and sheaves K, 0 are mounted on fixed parts of the trolly. The hoisting-rope L is anchored at N and is passed round the sheaves J, 0, J, K in the order named to the load-engaging hook M. In a modification in which two screws are used, the sheaves J are carried on a spindle between the two nuts, and the sheaves 0, K are mounted on a common spindle. In another modification, the lifting-apparatus is arranged symmetrically with respect to its point of suspension from the trolly, and the four sheaves are mounted in pairs on nuts working on the oppositely-threaded extremities of a single screw. In a further modification, the screw is arranged to traverse instead of the nut.

Fluid under pressure such as butane, propane &c. supplied from two or more sources connected at 2, 3 and delivered to an outlet 32 is controlled by valves 7, 8 actuated by a spring- loaded diaphragm 18 subject to outlet pressure and operating the valves through a cam 30 which can be rotated by a selector knob 23. The apparatus maintains a constant pressure in the outlet by actuating the valve situated below the deeper portion a of the cam until the corresponding source of supply is exhausted whereupon the diaphragm will descend sufficiently to operate the other valve to admit fluid from the other source. An operator can then turn the knob to a position corresponding to selection of the latter source so that the valve controlling the exhausted source will be closed and the exhausted supply cylinder can be replaced. An indicator visible through a window in a cover 19 or incorporated in the knob 23 is actuated by the diaphragm to indicate when the selected supply source is exhausted. Loose ball valves or lift valves may be provided in the inlets 2, 3 to prevent reverse flow.
