Title: Compound pressure brake with automatic control
IPC: F16D65/74
Filed: 1957-01-15
Abstract: 819,222. Hydraulic brakes. GOODYEAR TIRE & RUBBER CO. Jan. 15, 1957 [May 4, 1956], No. 1478/57. Class 103 (1). In order to provide automatic adjustment of the friction members in a disc brake by hydraulic means, an apparatus is provided comprising large and small diametered tandem cylinders, pistons operating in tandem therein, valve means to introduce fluid into the small cylinder to effect brake clearance adjustment, and means associated with the valve means to introduce fluid under pressure through the large cylinder to apply the adjusted brake friction members. In the spot-type disc brake illustrated, a number of piston and cylinder mechanisms 11 is provided in a fixed arcuate support 7 extending over a portion of the periphery of a rotatable axially movable brake disc 2. Adjacent one of the piston and cylinder mechanisms 11 is a transfer cylinder mechanism comprising a large and small diametered cylinder 26 housing a large and small diametered piston 32 controlled by a pressure control valve 43 between a pressure supply line 42 and the cylinder 26. In operation, fluid under pressure from a manually controlled pressure source is admitted to manifold 70. Plunger 62 of pressure-controlled valve 43 is in the normal position shown in Fig. 3 and the fluid flows through the passages 65, 66, 56, 57 in valve 43 to duct 39 and advances piston 32 should clearance exist between friction members and the brake disc. This displaces a larger amount of fluid from the large end of the transfer cylinder to the piston and cylinder mechanisms 11 via ducts 41 taking up brake clearance. As pressure increases in manifold 70, plunger 62 is moved to its second position closing of duct 57 and sealing the liquid between smaller end of piston 32 and the fixed head of the cylinder 26. At the same time fluid under pressure is admitted to duct 61 by uncovering of that duct by the plunger 62 which is forced upwardly against the force of the spring 64 and fluid is supplied through duct 61 to the larger end of the transfer cylinder and the piston and cylinder mechanism 11. When the pressure supply is released, plunger 62 is forced back by spring 64 closing off duct 60 and opening space 56 to the bore 65. A cup gasket 71 will not now permit direct return to the duct 69 from bore 65 and duct 74 and by-pass valve 75 permit regulated slow release of pressure about the gasket 71.

Title: The manufacture of new aromatic polyhydroxy compounds containing mercury
IPC: C07F3/12
Filed: 1928-01-18
Abstract: 312,246. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Jan. 18, 1928. Insecticides and fungicides comprise neutralreacting aromatic polyhydroxy compounds containing mercury which are obtained by reacting a polyhydroxy compound of the benzene series with a mercury compound, e.g. mercuric chloride in a neutral medium such as water, and neutralizing any acid reaction of the product, due to hydrolysis, by the addition of alkali. A dry finely-divided mixture of the polyhydroxy compound and a mercurizing agent may be dissolved in water at atmospheric temperature, the resulting solution giving no precipitate of mercury oxide or hydroxide on the addition of alkali. The solution of the components of the dry mixture may be hastened by the addition of a halogen compound of an alkali metal, ammonia, or an alkaline-earth metal, e.g. sodium chloride. The compounds may be obtained in the dry form by evaporating the solutions thereof, and pulverizing the solid residues, and may be combined with other water-soluble disinfecting agents.

Abstract: 629,957. Packaging. NICOLLE, C. Jan. 20, 1947, No. 1765. Convention date, Jan. 22, 1946. [Class 94(i)] In the production of a multi-cellular package for tablets and similar objects, the latter are placed between two thin sheets of polyvinal chloride or other resilient thermo-plastic material, one or both of which are stretched closely about the objects whereby the latter serve as stamping means forming recesses in said sheet or sheets, and the two sheets are united under heat and pressure along contacting portions around the objects so as to form closed cells conforming exactly in shape and size to said objects. As shown, fixed dies 2 and movable dies 2a, with embedded electric heating resistances 9, have openings 5 to accommodate spring- urged plungers 6 with heads 11 matching the tablets 17. The sheets 12, 12a are fed to the press through spacing rollers 14, while the tablets are inserted between the sheets by grooved or recessed arms 15 controlled by springs 19. Objects from a supply receptacle are moved by a distribute, ing plate, such as that described in Specification 527,756, and fall into the recesses 16, being supported therein by a plate 30 (not shown). A handle 24 on a common actuating rod 23 then turns spindles carrying cams 20 to allow the springs 19 to close the arms 15 and grip the objects', and the distributing plate is returned to its original position. The arms 15 are then slid transversely of the sheets 12, 12a by means of a carriage 18, 18a movable on guides 25 under the control of limit screws 26. The die 2a is lowered until the sheet 12 engages the lower plungers 6, the cams 20 are operated to release the arms 15 which are then withdrawn from the sheets, and the die 2a is further lowered to the closed position, shown in Fig. 5, to complete the sealing. The die 2a is then raised, and the completed package withdrawn to feed a fresh portion of the sheets between the dies, spacing of the sheets being ensured by an arm 29, Fig. 12, tapered at its forward end and projecting from the carriage 18, 18a. Symmetrical or asymmetrical cells are obtained according to the relative compressions of the plunger springs 7. Either or both dies may be movable, the carriage may move with respect to a stationary distributing plate, the operations of the press and loading device may be synchronised automatically, the sheets may be provided with printed indicia and they may be formed in the press with strengthening corrugations.
