Abstract: 401,437. Pressure-regulating valves. LIDSEEN, G., 830, South Central Avenue, Chicago, U.S.A. July 15, 1932, No. 20127. Convention date, March 25. [Class 135.] A pressure regulator has a needle valve member loosely supported by a spring loaded abutment coupled through toggle link mechanism to a spring loaded actuating bellows. The actuating bellows 20 is secured to a flange 21 on a plug 19 screwed in the casing and at its closed end is fitted internally with a bearer plate 23 for a loading spring 25 arranged within a tubular adjusting screw screwed into the plug 19. Externally the closed end is fitted with an abutment plate 22 engaging one link 36 of the toggle link mechanism. This link which is substantially disc shaped with a convex upper surface has a projection 37 loosely engaging a hole 38 in the casing and is formed with passage ways 40. A second toggle link 42 is arranged between a projection on the link and a hole in a spring loaded abutment plate 30. This plate is loosely guided by a tongue 31 working in a groove in the casing and is provided centrally with a curved depression to receive a corresponding head on the valve spindle which is secured in position by a bifurcated clip engaging an annular groove 35. The tapered valve member co-operates with a seat 6 held in position by bending over a flange on the casing and is so arranged that the point never leaves the passage way 8. The passage way 8 leads by way of a larger passage 5 to an inlet chamber c fitted with a strainer 1. The exterior surface of a closure plug 27 preventing access to the screw driver slot 26 for adjusting the load is made cylindrical to prevent easy removal and the plugs 12 and 19 also have cylindrical outer surfaces but have a notch 67 to receive a special removing wrench.

Title: Improvements in and relating to the preparation of complex iron compounds
IPC: C07F15/02
Filed: 1936-07-24
Abstract: Hexa - acetato - dihydroxy - carbamidotriferric salts which are useful as tanning agents, are prepared by reacting ferric salts with soluble acetates and urea in aqueous solution and adding alkaline substances before, during or after the reaction. One to three molecules of urea may be introduced into the complex, an excess of the theoretical amount being preferably employed. The reaction is desirably effected in highly concentrated solution at a temperature below 35 DEG  C.  According to the example, a mixture of sodium acetate, urea and sodium hydroxide in water is slowly stirred into an aqueous solution of ferric chloride, whereupon hexa-acetato-dihydroxy-tricarbamido-triferric chloride is precipitated; it can be crystallized from alcohol.  Other alkaline substances, such as sodium carbonate, ammonia and amines, may be used in place of caustic alkali.

IPC: F04D29/10
Filed: 1956-07-03
Abstract: 795,628. Stuffing-box substitutes; centrifugal pumps. ALLIS-CHALMERS MANUFACTURING CO. July 3. 1956, No. 20547/56. Classes 110 (1) and 122 (5). A sealing means for the substantially horizontal rotary shaft 36 of a pump suitable for pumping corrosive or other liquids comprises a rotor 46 which is mounted on the shaft and provided on one side with an annular flange 48 and deflecting means 53 extending between the flange and the periphery of the rotor, and a groove 24 which is formed in the casing of the pump for the reception of the flange 48 and has an inner face 49 so disposed that the radial distance from the axis of the pump to at least one point on such face is less than the radial distance from the axis to the outer edge of the face. The inner face of the groove 24 may be of frusto-conical form as may also be its outer face. Liquid entering the pump at 11 is centrifuged by the impeller 37. Leakage from the casing is prevented first by a rotor 42 having a flange 43 and recesses 44 whereby the liquid is turned back radially, and then by the rotor 46. This rotor 46 may optionally be provided with an outer flange 47 and the ribs 53 constituted by blades provided between recesses 54. The casing of the pump is built up of separate parts 6, 7, 8 recessed to receive the two rotors. A sleeve 22 carried by the casing part 8 co-operates with an L-section silicone rubber packing 64 to seal the outer face of the sleeve when the pump is stationary. This packing is clamped against a flanged member 56 on the shaft 36 by a clamping nut 63 and, while urged against the sleeve 22 by a garter spring 66 when the pump is inoperative, is disengaged by centrifugal action when the pump is working. A drain conduit 69 is connected with the cavity in which the seal 64 is located. An oil-slinger 67 prevents contamination of the fluid being pumped by oil leakage from the bearing 28.
