Patent GB-783084-A (GB)
IPC: H02K5/14
Abstract: 783,084. Brush-gear for dynamo-electric machines. GENERAL ELECTRIC CO. Feb. 28, 1956, No. 3255/56. Class 35. Relates to equipment such as a forced aircooled dynamo-electric machine for use in aircraft and comprising an integral assembly of brush-holder segments 20, vapour chambers 42 being intimately associated with the brushholders so as to operate at approximately the same temperature as the brushes for producing lubricating vapour and preventing rapid brushwear. As shown, each brush 18, is urged towards the commutator 17 by springs 19 and each brush-holder segment is made of aluminium alloy, or other material having good heatconductivity. A brush-holding box 21 of stain. less steel surrounds three sides of the associated brush and is screwed to the brush-holder. A sealing chamber 29 is defined about the periphery of the commutator by means of the brush-holder segments and is sealed on one side by ring 22 secured to the frame of the machine and made of insulating material, a close running clearance being provided between the ring 22 and a commutator shrink-ring 25. A similar running seal is provided at the opposite end of the commutator between the surfaces of the commutator segments 24, including their risers 27, and a stationary ring 33 of insulating material. A labyrinth seal is provided by slot 33s. The arcuate body portions forming the brush-holder segments 20 are interspaced by insulating members 36 to form a complete circle around the commutator and thereby define the space 29 thereabout. A spring 37 minimizes leakage between one face of each brush and the associated. box 21, and the opposite face is sealed by reaction pressure caused by spring 19 which bears against the inclined surface 18t at the top of the brush. In each of the brush-holder segments is provided the vapour reservoir chamber 42 in which brush-lubricating vapour is generated or to which such vapour is supplied, each chamber being joined with the space 29 through holes 43. As shown, the vapour generating devices each comprise a substance 40 of liquid-saturated wool or a solid capable of vaporizing, surrounded by a cylindrical screen 41. During operation, the cooling air flows over the outer surface of each segment 20 and, since the chambers 42 are formed in the metal of the segments, the rate of vaporization is closely matched to load requirements. Specifications 764,765 and 783,085 are referred to.

Patent GB-2006983-A (GB)
Title: Improvements in or relating to slide projectors
IPC: G03B23/04
Filed: 1978-11-10
Abstract: A magazine type slide projector usable with a rotary slide magazine has a sensor 25 responsive to vacant chambers of the magazine to switch a microswitch 24 into condition to supply power to a motor 11 driving an auxiliary magazine drive mechanism engagable with the magazine indexing rack 21. A second microswitch 27 is responsive to the condition of the slide change mechanism 5 and is connected in circuit with the first microswitch 24 and the motor 11 so that the motor 11 will be powered only when the sensor 25 detects a vacant magazine chamber and the slide change mechanism 5 is retracted so as not to impede movement of the magazine. The auxiliary magazine drive mechanism is controlled by a solenoid actuator 18 which is arranged to be energized slightly after power is supplied to the motor 11 and moves a spur gear of the auxiliary magazine drive mechanism into mesh with a worm gear 12 on the motor 11 output shaft. This causes drive to be applied from motor 11 to a spur gear meshed with the magazine indexing rack 21 so that the magazine is rotated quickly past vacant chambers thereof, the slide change mechanism 5 being inhibited during such fast movement of the slide magazine. When the sensor 25 again senses an occupied magazine chamber, the motor 11 is stopped and normal projector operation resumes. <IMAGE>

Title: Manufacture of sanitary fittings
IPC: B29C51/30
Filed: 1978-11-30
Abstract: A process for the manufacture of sanitary fittings and other bathroom fittings involves forming a thermoplastic blank 16 previously heated to its softening temperature by placing it onto a metal mould 1 and applying suction through perforations 9 in the surface of the mould 1 to draw the blank onto the inner surface of the mould while eliminating air between the blank and the surface of the mould. A metal former 5 is then applied to the blank 16 to press it against the mould 1, while air trapped between the former 5 and the blank 16 is allowed to escape through perforations 12 in the former 5. After the blank has been compressed between the former 5 and the mould 1, the former 5 is withdrawn while compressed air is applied through the perforations in the mould and in the former in order to facilitate separation of the finished fitting therefrom. <IMAGE>

Title: Recoverable neutron absorbers
IPC: G21C19/46
Filed: 1981-01-23
Abstract: In the reprocessing of irradiated nuclear fuel elements the nuclear fuel material is separated from the material which forms the remainder of the elements by dissolving the nuclear fuel material in nitric acid. Neutron absorbers are added to control criticality. The neutron absorbers comprise pellets each having a core of neutron absorbing material encased in a sheath of a material which is resistant to attack by acid, the core or sheath being magnetic. The sheath protects the core of neutron absorbing material from attack by the acid and the magnetic content of the core or sheath enables the absorbers to be recovered for reuse by magnetic separation techniques.
