Abstract: 363,632. Fluid pressure bra k e s. HOUPLAIN, G., 40, Rue Bargue, Paris. Sept. 16, 1930, No. 27626. Convention date, Nov. 2, 1929. [Class 103 (i).] Fluid-pressure brake mechanism of the kind comprising two pistons of which the smaller is first moved to take up the slack in the transmission, the second and larger being rendered operative subsequently comprises a small piston 9 the pistonrod 11 of which is connected to the transmitting mechanism and which is slidable in the tubular piston-rod 4 of the main piston 3. The central part of the piston 3 normally engages a seating on the end of the main cylinder 1 as shown, so that the inlet passage 2 for the compressed air is cut off from this piston but communicates through the passage 5 in the piston, with the piston-rod 4. When the compressed air is supplied to the passage 2, the small piston 9 therefore moves at first alone until upon contact of the brake shoes with the wheels, the pressure rises sufficiently to open a spring- loaded valve 22, thereby supplying also the chamber 8 of the cylinder 1. Clutch members 14 carried by the piston-rod 4 and normally held disengaged from a rack 12 on the piston-rod 11 by projections 21 on the cylinder 1 couple the pistons together upon initial movement of the piston 3. The application of the device to vacuum brakes is mentioned. The Specification as open to inspection under Sect. 91 (3) (a) describes also a construction in which the cylinders 4, 8 are connected by an open passage formed in the wall of the cylinder 4 and terminating at a point which is passed by the piston 9 during its initial outward movement. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in friction facings and process of making same
IPC: F16D69/02
Filed: 1920-10-01
Abstract: 174,685. Goold, L. W., (Raybestos Co.). Oct. 1, 1920, Clutches, friction.-Relates to clutch and brake facings made from felted and unwoven asbestos fibre saturated with a binder, and consists in a process which results in great tensile strength, hardness, and resistance to attack by oil or water. Short, or low-grade, asbestos fibre is ground and pulped, and to the pulp is added an oxidizing- agent, for example 1.6 per cent of red oxide of lead. The pulp is made into sheets, for example on a wet-board paper machine, pressed in an hydraulic press, dried, calendered to the required thickness, and cut to shape. The facings are then saturated for half-an-hour in a binder consisting of a drying oil and a bitumen, for example 94 per cent of linseed oil preferably double-boiled, and 6 per cent gilsonite or other asphalt, thinned with gasolene to 33‹ BÚ, after which they are steam-dried for 2-3 hours at about 200‹ F. to drive off the gasolene, which may be recovered, and baked for 12 hours at about 250‹ F. Thev are then immersed for 2-3 minutes in 66 per cent of linseed oil and 33 per cent gasolene, baked for 24 hours at 300‹ F., and sand-papered to size. During the baking, the solubility in gasolene of the linseed oil is reduced by oxidation in the presence of air and of the oxidizing-agent, and may ultimately approach zero. Care is to be taken to avoid overheating at this stage, as the reaction is exothermic. The tensile strength of these facings is stated to exceed 3000 lb. per sq. in., and their Brinell hardness-number to exceed 15.

Title: Improvements in or relating to methods of applying protective layers to reflecting metal surfaces
IPC: B32B15/08
Filed: 1951-11-30
Abstract: A protective layer is formed on a reflecting metal surface formed on a thermosetting layer of lacquer which has been hardened by heating, by covering the metal surface with a layer of a thermosetting lacquer which is subsequently hardened at a temperature at least 15 DEG C. lower than that at which the supporting layer of lacquer was hardened.  A preferred reflecting surface is a layer of aluminium applied to the supporting layer of lacquer by vaporization in a vacuum.  Preferably the same lacquer is used for supporting and protecting the metal surface; a specified lacquer is a mixture of a urea formaldehyde condensation product and a non-drying alkyd resin, this mixture being applied to the metal layer as a solution in xylol-butanol.  The coating may be applied to the reflecting surface, which is subsequently rotated rapidly, or it may be sprayed thereon. In an example, provided on a plate having a part-spherical surface, the supporting lacquer is muffled at 150 DEG C. and the aluminium mirror supported on this is coated with a solution of "Paralac (Registered Trade Mark) 6001," a urea formaldehyde condensation product, and "Sigmol 706," a non-drying alkyd resin, in a xylol-butanol mixture having a viscosity 9 to 9.5 degrees Engler at 20 DEG C. by application of a small quantity of the solution to the mirror with subsequent rapid rotation of the latter.  The coating is then dried at 60 DEG C. for 20 minutes and then muffled at 115 DEG C. for more than 1 1/2 hours.
