Abstract: 1,260,801. Radiators; hot-plates. S. G. A. SWALES. 9 Oct., 1970 [21 Jan., 1970], No. 2966/70. Headings F4S and F4W. A panel-type radiator 1 is pivotally mounted so that it can be swung from its normal vertical position into a horizontal position to serve as a hot-plate. The radiator inlet and outlet connections are embodied in swivel couplings 5 mounted on brackets 6 secured to a supporting surface 7. The radiator can be retained in a horizontal position by a folding strut 12 of Y-form having a knuckle joint 13. The strut is folded upon itself and accommodated behind the radiator when the radiator is in its vertical position. A releasable spring-loaded catch 15 locks the radiator in the horizontal position. In an alternative arrangement (Fig. 3, not shown) a telescopic spring-loaded articulated strut can be used to support the radiator. A detachable sheet (18) of mesh or grid structure may be provided to facilitate the radiator's use as a hot-plate, the sheet being stored behind the radiator when not required. A supplementary tank (20, Fig. 1) incorporating an immersion heater may be located in the radiator inlet line for bringing the hot-plate into service when the radiator system is inoperative. The radiator includes an internal baffle arrangement (4, Fig. 1).

Abstract: 546,548. Feeding articles in succession. BRITISH THOMSON-HOUSTON CO., Ltd. March 7, 1941, No. 3100. Convention date, March 9, 1940. [Class 117] [Also in Groups XXXV and XXII] In a transformer or reactor, the core comprises stacks of E-shaped laminations 13 of which the outer elements are crimped or bent as at 20 so as to provide a self-clamping structure when inserted within the winding structure. The method of assembly comprises stacking two groups of laminations on opposite sides of the winding structure, pushing a sufficient number from the bottom of the stacks towards each other with the outer elements in advance of the central groups, applying benders 38, 39, Fig. 23, to the overhanging tips of the outer elements, continuing to push them until they meet or abut against a gap spacer, and forcing the central group into registry with the outer elements so that the bent portions of the latter in the case of the middle legs grip the inside of the winding structure and, in the case of the outer legs, hold the central laminations firmly together. Cement 23, introduced through a duct 45, may also be used to assist in firmly securing the laminations within the winding structure. A machine for carrying out the above steps and comprising cam-operated pusher and bender elements, a gauging means for ensuring that a correct number of laminations are delivered from the stacks, an escape block designed to ensure that only laminations securely engaged by the pushers are fed forward to the bending positions, and a pump delivering cement in appropriate quantities is described in detail in the Specification.

Title: Improvements in or relating to the production of lubricating oils
IPC: C10G50/02
Filed: 1931-01-30
Abstract: Catalysts for use in the production of lubricating oils by the polymerization of olefines, and comprising finely divided nickel, an absorbent earth such as Florida earth and anhydrous aluminium chloride, are prepared by evaporating to dryness a mixture of Florida earth and nickel nitrate solution, heating to convert the nitrate to oxide, reducing the oxide with hydrogen at 200-250 DEG  C., impregnating the product with a solution of anhydrous aluminium chloride in ethyl alcohol, and removing the alcohol by evaporation. Reference has been directed by the Comptroller to Specification 326,322, [Class 2 (iii), Dyes &c.].ALSO:Lubricating oils are obtained by polymerizing olefines under pressure in the presence of a catalyst comprising an intimate mixture of an absorbent earth and finely divided nickel, with or without other inert substances or catalysts. Preferably the catalyst consists of Florida earth impregnated with finely divided nickel and also with anhydrous aluminium chloride. Fuller's earth, kieselguhr, or bauxite may also be used as absorbents.  The catalyst may be prepared by evaporating to dryness a mixture of Florida earth and nickel nitrate solution, heating to convert the nitrate to oxide, reducing the oxide with hydrogen at 200-250 DEG  C., impregnating the product with a solution of anhydrous aluminium chloride in ethyl alcohol, and removing the alcohol by evaporation.  According to an example, ethylene is forced at 70 atmospheres pressure into an autoclave containing a catalyst prepared as described above, and the temperature is maintained at 15 DEG  C. while the pressure falls during 10 hours.  Distillation of the liquid product yielded some lubricating oil; and a further quantity was obtained by treating the catalyst with water and distilling off the oil thus liberated.  Reference has been directed by the Comptroller to Specification 326,322, [Class 2 (iii), Dyes &c.].
