Patent GB-785292-A (GB)
IPC: H05B3/68
Abstract: 785,292. Electric grills and hot plates. SIMPLEX ELECTRIC CO., Ltd. Nov. 5, 1954 [Nov. 5, 1953], No. 30565/53. Class 39(3) An electric grill comprises a sheathed heating element 29 bent to fit into a rectangular strip metal frame 10 so that the element 29 lies adjacent the edge of the frame 10 at the corners of which the element is bent into open loops 31 facing inward so as to give a greater length of element at the corners to ensure more even downward radiation. The element is of uniform power per unit length and fits, into an aperture in a hob 16 which may be above an oven, and a cooking pot may be supported on or above the element. The looped corner parts of the heater may include spiral convolutions. The element may be of vertical oval cross section and the sheath may have ribs 32 as in Specification 592,124, so that if the cooking pot rests on the element, there is only line contact between them, in order that the heating of the pot does not interfere with the uniformity of the downward radiant heating e.g. for toast. The element 29 may be shaped as in Fig. 1 to give an inner heating line with loops 24, 27 as shown, the ends of the element being bent down at 25 to enter a contact box 18 with contact pins 19. The element may be in two parts with a switch for connection in series or parallel or singly and the corner loops are closer together than the straight or slightly curved side parts of the heater. A reflector 34 with a detachable wire handle 3 and comprising rectangular aluminium sheet with opposed flanges 35 is supported below the element on pins 37 and a collar on a stud 39 projecting below the hob or may be supported above the element. The frame 10 has reinforcing cross strips 11, which are slotted at intervals to support the element or elements 29.

Patent GB-2044198-A (GB)
Title: Rapid transit railway truck assembly
IPC: B61F5/38
Filed: 1979-03-21
Abstract: Known truck assemblies are not really suitable for rapid transit systems as they are too noisy, too heavy and are unable to negotiate sharp curves. The railway truck assembly of the invention overcomes these disadvantages by having a pivot connection between its bolster and the truck frame elements which, in co-operation with direct transmission of the load to the truck frame through the opposite ends of the bolster, allows the use a relatively thinner and centrally nonbulging bolster. This railway truck assembly has a bolster 3 which is substantially bodily displaceable with the car body 2. A pair of side frames 31 and 32 are laterally restrained by means of a link 37, relative to the bolster 3 and support the opposite ends of the bolster. A pair of steering yokes 13 and 14 are longitudinally restrained relative to the car body 2, and pivoted together for radial steering of the respective wheel axes 20 connected thereto. The side frames 31 and 32 are slidably supported by the yokes 13 and 14, and are laterally restrained relative thereto by means of links 38 and 39. The bolster 3 is connected to the side frames 31 and 32 by a centreless pivot connection. <IMAGE>

Patent GB-2052463-A (GB)
Title: Chlorination of Aluminous Material at Superatmospheric Pressure
IPC: C01F7/60
Filed: 1980-05-29
Abstract: Aluminous material is chlorinated in the presence of a reducing agent at pressures greater than three atmospheres. A greater than linear increase in reaction rate obtained at superatmospheric pressures is a feature of the chlorination reaction which is employed to increase aluminum chloride production rate. Choice of pressure used is governed more by mechanical limitations than by an upper limit inherent to the chemical reaction. Alpha-alumina is preferably chlorinated to form satisfactory yields of aluminum chloride when pressures in excess of 10 atmospheres are used.

Title: An Electrical Machine, Especially an Alternator for Motor Vehicles
IPC: F01M1/00
Filed: 1981-01-08
Abstract: An electrical machine, especially an alternator for motor vehicles, is proposed, the rotor 12 of which is mounted in at least one roller bearing 30. The outer track ring 44 of the bearing consists of sintered steel and is impregnated with an oil as a lubricant. Moreover, a supply of lubricant (50) can be provided in the housing of the machine from which the lubricant can arrive at the periphery of the outer track ring 44 of the bearing under the action of centrifugal force. Due to the capillary action in the track ring 44 and its deformation occurring periodically during operation, the lubricant is transported to the bearing surface of the outer track ring 44 and from there is transported to the inner track ring of the bearing by the rollers 30. In that manner, used lubricant is continually replaced by fresh lubricant and the life of the bearing is increased. If necessary, the roller bearing can also be filled in the usual manner with a grease compatible with the lubricating oil. <IMAGE>
