Abstract: 1344503 Universal pivots ROBERT BOSCH GmbH 7 May 1971 [16 May 1970] 13660/71 Heading E2F [Also in Division F4] A pivotally adjustable mounting for a vehicle lamp having a housing 1, preferably of plastics material, containing a reflector 2 and a bulb 17 comprises a socket 5 made of elastic plastics material which abuts both the rear wall 4 of the housing and a vehicle body panel 6, a metal plate 7 which is fixed inside the socket 5 and is secured to the panel 6 by screws 10, and a holding plate 15 which is located inside the housing 1 and is secured to the plate 7 by a threaded sleeve 12 which extends through an opening 14 in the rear wall 4 of the housing. The rear wall 4 is of spherical or cylindrical form and. both -the plate 15, which abuts the inside surface of the wall 4, and a part 8 of the plate 7 which abuts the outside surface of the wall 4, are of complementary form so that pivotal adjustment can take place within limits defined by the size of the opening 14. The connecting cable for the bulb 17 passes through a boss 20 in the panel 6 and through the threaded sleeve 12. Both the housing 1 and the socket 5 may be asymmetrical with respect to their curved surfaces so that by inverting one or both of them various ranges of adjustment may be obtained. An aperture 21 for the discharge of condensation from inside the lamp is located at the junction of the housing and the lens 3.

Abstract: 459,601. Radiators. CROSS, R. C., 33, Midford Road, Odd Down, Bath. May 9, 1935, No. 13675. [Class 29] [See also Groups XXVII and XXXI] An internal-combustion engine is entirely surrounded by a heat-insulated casing 5 having inlets and outlets controlled by heatinsulated shutters, power-operated by fluid pressure under the control of a thermal device. On a motor vehicle the casing comprises the bonnet which has insulating material, e.g. silica wool, fastened to the interior thereof, further material being arranged under the sump and vertically at the rear of the engine. Radiator shutters 8, also covered with heatinsulated material, open simultaneously with air exit shutters 9 under the control of a thermal device 16. The device 16 acts through a relay device comprising a valve admitting lubricating oil under pressure from the engine to act on two pistons in a cylinder 10, the pistons being coupled to the shutters by linkage 11 ... 14. When the engine stops the shutters immediately close under the action of springs 17. The Provisional Specification describes the combination of ordinary radiator shutters, controlled by a thermal device, with heatinsulated shutters controlled by the oil pressure of the engine.

Filed: 1921-05-25
Abstract: 182,287. British Thomson - Houston Co., Ltd., (General Electric Co.). May 25, 1921. R÷ntgen-ray and like apparatus.-Relates to X-ray apparatus for use in radiography and especially to the kind in which the X-ray tube, together with the supply transformer, is immersed in oil within a container. In order that distinct radiographs may be obtained, without the use of a heavy supporting arm for the container, a member, yieldable in one direction only, is attached to the container and positioned in contact with the subject. The supporting-arm 5 of the container 1 comprises hinged members which enable the container to be moved, within limits, to any desired position. The weight of the container is counterbalanced by springs, in the hollow rods 14, 14<1>, connected to cables 15, 15 which pass over the eccentric drum 16. The tube 19 is in line with the X-ray beam passing through a window 3 in the container, and the tube 20 telescopes therewith and bears against a spring 21, which, when compressed, causes the tube 20 to remain in contact with the subject. The post 22 is pivoted at 24 and a spring is positioned at the pivot which, on the rotation of the post 22, imposes a torque thereon, so that pressure may be maintained between the container 1 and the subject.
