Title: Improvements in electric heating mantles
IPC: H05B3/00
Filed: 1960-02-01
Abstract: 939,664. Electric heating mantles. ISOPAD Ltd., and H. REIK. May 1, 1961 [Feb. 1, 1960], No. 3464/60. Class 39 (3). A heating mantle, shaped to receive and surround a vessel, includes a woven metal wire mesh heating element arranged on or near the inner surface of the mantle, and an external lagging of heatinsulating material The wire mesh 12, Fig. 1, to which contact is made by a metal band 15, and the strands of which may or may not be insulated from one another, is lagged by asbestos 13 contained within metal wall 14, a layer 11 of insulation forming the heating surface of the mantle, which may be applied to the wall 10 of a glass of water. A hemispherical mantle (Figs. 2 and 3, not shown), may be formed by sewing sectors of the mesh together with wire, and providing contact rings at the equator and near the bottom. A cylindrical mantle (Figs. 4 and 5, not shown), may have contact rings at its two ends or, if the mesh is not completely closed upon itself, contact bars extending axially along the unclosed edges. In a modification (Figs. 6 and 7, not shown), the heating current is supplied to an uninsulated heating conductor conductively attached to the mesh in a zig-zag or helical path, whereby the conductor and the mesh share the heating current. The metal current supply rings or bars may be formed by spraying; the provision of an insulating layer at the heating surface, as in Fig. 1, permits application to liquids or metals; and the wires of the mesh, of which details of size and loading are given, may be of stainless steel. The Provisional Specification also refers to the use of nickel, chrome, copper/nickel, or copper, and to heating panel and heating tape structures.

Classes 79(2), 79(3) and 79(5) [Also in Group XXXIV] A power unit for a motor driven truck consists of a frame 16, carrying a ground wheel 18, and a motor 17, drive connections from the motor to the ground wheel, a vertical upper pivot bearing 32 for the frame above the motor, carried by a support 40, a lower pivot bearing 23 located between the motor 17 and the ground wheel 18 and carried by a bracket 43 from the support 40. In the construction shown in Fig. 3, the frame 16 carries a fork formed of side plates 19, 20, and a plate 21, having bearings 45, 46 for the wheel 18. The drive from the motor 17 to the wheel 18 is by means of chain drives 61, 55, and a countershaft 51. Brake shoes acting on a drum 60 (see Group XXXIV) carried by the motor drive shaft, are adapted to be moved into braking relation by anti-clockwise movement of a lever 72 mounted at 74 in the frame 16, by the action of a push rod 77 passing through the axis of the bearing 32. The rod 77 is adapted to be depressed by the action of a cam 81 carried on the boss of a tiller arm 15 (Fig. 4), by means of which the power unit is rotated for steering the vehicle. In a modified construction (Fig. 6, not shown), the wheel 18 is mounted at one side only on the casing of a gear train which replaces the chain drive from the motor 17. The cam 81 is arranged so that 'braking occurs when the tiller arm is in a raised or lowered position, but the brakes are released when the arm is in a generally horizontal position.

Patent GB-374864-A (GB)
Title: Improvements relating to the production of ethylene oxide
Filed: 1931-02-10
Abstract: Ethylene oxide is produced from chlorhydrin by treatment with alkali, solutions of chlorhydrin and alkali being admixed at room or lower temperature and the ethylene oxide produced being removed at a relatively low temperature, e.g. between 30 and 60 DEG  C., and preferably at reduced pressure.  The solutions used may, for example, contain 16 per cent of chlorhydrin and 30 per cent of caustic soda. The oxide may be removed in a current of air or gas, or by distillation.  Thus solutions of chlorhydrin and caustic soda are mixed at 10-20 DEG  C., and the mixture admitted continuously to a packed column evacuated to 95-105 mm.  The liquid may be used as reflux liquid for the vapours passing up the column.  Most of the oxide passes off immediately, and the remainder is removed by heating slightly the liquid accumulating at the bottom of the column. Residual liquid is withdrawn from the bottom of the column.
