Patent number: 4442973Abstract: A rotatable or twist-on rail fastening assembly for securing a railway rail to an anchoring support therefor is comprised of a generally S-shaped torsional spring rail clip and a post-type mounting or chair adapted to cooperate therewith. The rail clip includes a central leg, a tie anchor portion and a rail bearing portion comprising a pair of loops spaced on opposite sides and extending from opposite ends thereof, each of the loops including an arcuate and a terminal leg. The chair is adapted to have the one loop of the S-shaped clip rotated around the post.Type: GrantFiled: January 27, 1981Date of Patent: April 17, 1984Assignee: True Temper Railway Appliances, Inc.Inventor: Graham M.

Patent number: 4442073Abstract: A method for recovering superalloy scrap is disclosed. The method involves oxidizing superalloy scrap in an aqueous acidic medium. The aqueous acidic medium has an oxidation potential sufficient to oxidize nonferrous additive superalloy elements to insoluble oxides thereof and to oxidize major superalloy constituents to aqueously soluble species. The insoluble solids from the aqueous solution are separated when the aqueous solution is extracted with an aqueously substantially insoluble tertiary amine to form an organic phase and an aqueous phase. The aqueous phase contains essentially nickel and chromium values. The organic phase is sequentially extracted with aqueous solutions which selectively solubilize individual metal value species to form individual aqueous solutions having substantially single metal value species therein. The metal value species solutions are processed to obtain substantially pure metals.Type: GrantFiled: May 21, 1982Date of Patent: April 10, 1984Assignee: University Patents, Inc.Inventors: Douglas J. Robinson, Aniedi O. Ette

Patent number: 4373835Abstract: An improved removable closure plate arrangement providing a liquid-tight seal in an elongated floatable offshore hollow tubular column structure. The closure plate being adapted for easy removal and including a centrally located pull member removably connected to the upper and fixedly connected to the lower portion of the closure plate with the closure plate being removably connected about its periphery to the inside surface of the column.Type: GrantFiled: June 23, 1980Date of Patent: February 15, 1983Assignee: McDermott IncorporatedInventor: James A. Haney

Patent number: 4373588Abstract: An apparatus for pneumatically actuating slave devices in direct response to the discharge of a dry chemical fire extinguishant is disclosed comprising at least one main fire extinguisher from which pressurized dry chemical fire extinguishant passes into a main discharge pipe, and a cartridge containing a pressurized gas connected to the main discharge pipe through an actuator valve. The actuator valve includes a resilient check closing the valve due to the pressurized gas in the cartridge and a piston having a head fit into the actuator valve at sufficiently close tolerance to minimize gas transfer therethrough. The piston head is disposed toward the main discharge pipe and an integrally connected base portion faces the tip of the check and is disposed such that depression of the piston head into the actuator valve moves the check, opening the valve and releasing the contents of the cartridge into a secondary discharge pipe.Type: GrantFiled: October 27, 1980Date of Patent: February 15, 1983Assignee: Chemetron CorporationInventors: Kenneth T. White, Harold F. Roberts

Patent number: 4361196Abstract: A quick release, high torque coupling for interconnecting the bit and drive member in a mine roof drill has axial-locking and torque-transmitting structure integral with the drill members. A plug on the drive member is adapted to be releasably received within a mating socket in the bit and has an axial-locking segment on its outermost end complementally configured with respect to an acircular constriction in the socket to permit insertion of the axial-locking segment into the socket beyond the constriction. A torque transmitting segment on the plug cooperates with the constriction to limit relative rotation of the bit and drive member between oppositely directed torque-transmitting positions. In one of the torque-transmitting positions, the constriction and axial-locking segment are misaligned such that the plug is restrained against axial retraction from the socket.Type: GrantFiled: July 11, 1980Date of Patent: November 30, 1982Assignee: Carmet CompanyInventor: Gettys D. Hoyle, Jr.
