Abstract: A bracket (10) is utilized to mount a mailbox (11) to a wide variety of stanchion configurations (39, 41, 42). The bracket (10) includes opposed side walls (18), opposed end walls (20) and a bottom surface which includes rib members (25). Spaced flanges (35) depend from the bottom of the rib members (25) and have aligned bores (37) therein permitting the bracket (10) to be mounted to a stanchion (42) of one configuration. Apertures (38) in the flanges (35) permit the bracket (10) to be mounted to stanchions (39, 41) of other configurations. Lug members (22) on the side walls (18) are received in apertures (55) in flanges (48) depending from the bottom wall (47) of the mailbox (11) to attach the mailbox (11) to the bracket (10). Holes (56) formed in the flanges (48) and holes (57) formed in additional flanges (52) depending from the bottom wall (47) of the mailbox (11) allow the mailbox (11) to be directly affixed to various stanchion configurations.

Abstract: A hydraulic valve of the type having a plurality of flow directing spools and valve bodies, normally disposed in a stack, or sectional control valve assembly, with registering like passageways on adjacent valve bodies in fluid communication. An open center pilot arrangement is provided to initially control the pressure of fluid supplied to an output passageway of an individual valve when its spool is moved to a position to supply fluid to a load connected thereto. A balanced flow control is disposed in each valve body between an inlet passageway and an outlet passageway and to a loop and an output passageway. The flow control is operative in response to the pressure in one of the output passageways of the valve body to control the proportionate flow of the fluid to the output passageway and the outlet passageway of the valve body. A number of individual valves may be operated in a stack in such a manner that an "upstream" valve will have "priority".

Abstract: A fluid pressure device comprising a pump or motor having a rotating internal assembly comprising linear pistons and cylinders operated through a "swash" plate to actuate the pistons to provide output pressure. The swash plate is mounted to the drive shaft through a universal connection and the cylinder and piston assemblies are coupled to their component parts through universal swiveling ball and socket connections. Special spring washers are provided for insuring a sliding seal between the internal cylinders and a valving plate, and the valve ports are designed for noise minimization.

Abstract: An orbital device in which the effective roots of the internally extending teeth on an orbital member is equal to the radial dimension of the fluid ports. This is achieved by providing grooves in the surfaces of the orbital member adjacent the roots of the teeth. The shape of the ports is complimentary to that of the internal teeth on the orbital member.
