Abstract: 821,835. Impregnated electric contact brushes. STACKPOLE CARBON CO. Oct. 19, 1955 [Nov. 9, 1954], No. 29919/55. Class 140. A dynamo-electric brush, capable of prolonged life at high altitude, comprises a body of electrically conductive carbonaceous material having lithium carbonate distributed in the body. The brush may be produced by impregnating a block or plate of material for making dynamoelectric brushes, produced in accordance with standard practice, with a lithium compound that is convertible to lithium carbonate, after which such conversion is effected. Vacuum impregnation using an aqueous solution of lithium acetate may be carried out followed by drying at an elevated temperature and these steps may be repeated. The impregnated material may then be heated in a closed container packed with coke to convert the acetate to the carbonate. The material may then be subjected to further vacuum impregnation with an aqueous solution of ammonium carbonate, dried at an elevated temperature and then exposed to an atmosphere of carbon dioxide under pressure, followed by vacuum-drying. Alternatively the brush material may be vacuum-impregnated with an aqueous solution of lithium hydroxide monohydrate, dried at an elevated temperature, similarly impregnated with an aqueous solution of ammonium carbonate and then heated to convert the lithium hydroxide to the carbonate. U.S.A. Specification 2,414,514 is referred to.

Title: Improvements in brake mechanism
IPC: F16D65/52
Filed: 1932-10-26
Abstract: 414,338. Brakes. ROCKWELL, E. A., and EVANS, E. R., 1826, Diversey Parkway, Chicago, U.S.A. Oct. 26, 1932, No. 29955. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 27, 1932]. [Class 103 (i).] A vehicle - brake mechanism comprises two controls for applying the brake or brakes and means in the connection between one control and the brake or brakes for taking up slack automatically during a brake-applying movement of the other control. In Fig. 3, which shows a power unit 16 controlled by a pedal 18 and an independent emergency lever 40, brake rods 26, 30 are connected to a lever 24 having a lost-motion connection with the power-unit shaft 22 and the emergency lever is connected to the lever 24 by an adjustable link 46 embodying an automatic slack take-up device. The lever 46 has two parallel slots 50, 54 and normally a pin 52 on the lever 40 engages the lower slot 50. When the brakes are applied by the power unit and slack is excessive the link 46 is moved to the right until the pin 52 engages the slot 56; the link then drops under gravity about its pivot 44 together with the lever 24 and the pin engages the shorter slot 54 and thereby reduces brake clearance by limiting the return of the various parts. The device may be reset by means of a lever 68 pivoted to the emergency lever and actuating a rod 70 having a pin-and-slot connection 63, 65, Fig. 9, with a pawl 62 spring-pressed to engage a rack 60 to hold the emergency lever in any position. When the brakes are applied by the power unit the rod is lifted by the lever 68 and a projection 72 on the rod raises the slotted end 48 of the link 46 so that the pin 52 engages the slot 50 and on release of the brakes the pin returns to its original position shown in Fig. 3. To indicate to the driver that the slack has been taken up, the slot 54 has a corrugated face 55 so that when the pin 52 moves into the slot a warning noise is produced. In a modification, the pedal 96, Fig. 7, is connected by a slotted link 108 to a pin 116 on an arm 84 rigid with a shaft 80, which also rigidly supports a double-arm lever 86 connected by rods 90, 94 to the brakes, a second slotted link 126 connecting the pin 116 to a pin 122 on an emergency operating-lever 118. The operation of the device for taking up slack is similar to that already described, the link 126 corresponding to the link 46, Fig. 3. Operation of the brakes by the lever 118 will, if there is sufficient slack, cause the pin 116 to engage in the upper slot 114 of the link 108.

A process for making scintillation screens comprising the step of treating at least one surface of a light transmitting body with a liquid coating of a substance in solution, e.g. Silicone Resin M.S. 804 in toluene and having an absolute viscosity of 2À4 to 3À2 poises over the range 17‹C. to 13‹C., the coating having the properties of becoming tacky on evaporation, softening on subsequent heating and solidifying from the softened state by subsequent cooling, the solidified product being light transmitting, followed by the steps of adding solid phosphor material to the coating in the tacky state and heating to a temperature sufficient to soften the coating without changing its chemical composition so that the phosphor impregnates itself into the heat softened coating which on cooling creates a solid phosphor impregnated layer on the body. The light transmitting body can be a flat or curved, e.g. semi-cylindrical, sheet of methyl methacrylate, polystyrene or glass. The flat sheet can be coated on one side by dipping and the curved sheet by brushing the inner surface. The heating of the coated body can be from 80‹C. to 90‹C. for 5 to 30 mins. After cooling excess phosphor is blown off with compressed air. The phosphor particles can be caused to sink just below the surface of the coating by short heating at 135‹C. The surface density of the preliminary coating can be 4-12 or 8-14 mgm./cm.<SP>2</SP> and of the phosphor impregnated coating 20 mgm./cm.<SP>2</SP> The phosphor can be zinc-oxide, zinc sulphide or barium sulphate in the form of small crystals.
