Abstract: ABSTRACT           An electrical connector has a coupling nut provided with ratchet teeth on one end thereof for cooperating with a spring, so that the coupling nut is harder to rotate in one direction than the other. The spring is formed as a leaf spring having an elongate arm which cooperates with the forward and rearward faces of the ratchet teeth extending from the coupling nut. The relation between the leaf spring and the ratchet teeth is such that any compressive force acting on the spring during turning of the coupling nut is relatively light, and so the spring does not buckle as the coupling nut is turned. In one embodiment, the spring is in tension during rotation of the coupling nut in its uncoupling direction, and in compression only during rotation of the coupling nut in its easy direction, when the force is light. In another embodiment, compressive forces during rotation in the uncoupling direction are minimized by a rounded surface on the spring.

Abstract: ABSTRACT OF THE DISCLOSURE            An improved child resistant end closure wherein most of the pull tab for an easy opening end is mounted within a bead formed on the end panel which obstructs access to the ring or lift portion of the tab and prevents grasping and lifting it.          The tab and/or the end panel are slightly bowed in such manner that the tab upon fastening by the rivet to the end panel is sprung toward the end panel so that the ring portion of the tab is biased toward the panel below the bead.  The shape of the bead and the ring or grasping portion provides a digitally operable structure which permits an adult to insert his nail between the tab and external bead to lift the ring while flexing the end panel so that the ring may be further lifted to break free the tab hinge and then break the score defining the openable segment of the end panel, or alternatively the lift portion may be pried up by a tool entered into a slot provided beneath the ring.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved remote control assembly for mechanically con-trolling the operation of a hydrostatic pump which may be used to power the attachments on a tractor-like vehicle.  The assembly in-cludes a first control unit positioned at a first remote location on the tractor and a second control unit positioned at a separate and distinct remote location.  The assembly includes a control arm secured to a pump control element whose rotation controls the pump operation.  A pivot arm is pivotally carried by the control arm and has a first control cable from the first control unit connected to one end and a second control cable from the second control unit connected to the opposite end.  The assembly is con-figured such that when the first control unit is locked in a neu-tral position, the second control unit is operable to rotate the pivot member about its first end to operate the control arm and when the second control unit is locked in a neutral position, the first control unit is operable to rotate the pivot arm about the opposite end to operate the control arm thereby enabling the pump to be selectively controlled from either of the two remote locations.

Abstract: MASTER CYLINDER HAVING A PROPORTIONING AND METERING      VALVE ENCAPSULATED IN SEPARATE OUTLET PORTS                        ABSTRACT OF THE DISCLOSURE A tube seat assembly for retaining a proportioning valve which is located in an outlet port of a master cylinder.  The tube seat assembly has a cylindrical body with an axial bore having first, second and third diameter sections.  A radial bore is located in the second diameter section adjacent a shoulder which separates the second and third diameter.  A sleeve has a first diameter section concentric to said second diameter section of the axial bore and a second smaller diameter section which extends past the shoulder into the third diameter section of the axial bore.  A seal surrounds the second diameter section of the sleeve and separates the second diameter section from the third diameter section of the cylindrical body.  A spring connected to the cylindrical body urges the sleeve toward the shoulder in the axial bore.  Fluid from a pressurizing chamber in a master cylinder enters the third diameter section of the cylindrical body, passes through the sleeve and out the first diameter section of the cylindrical body for communication to the brake fluid distribution system.  When the pressure of the fluid from the pressurizing chamber reaches a predetermined value, the force created by the pressurized fluid acts on the first diameter of the sleeve and overcomes the spring to move the sleeve toward a seat in the third diameter section to interrupt the flow through the sleeve.  Thereafter, any increase in the fluid pressure from the pressurizing diameter acts on the second diameter of the sleeve and moves the sleeve toward the shoulder in the cylindrical body to allow a portion of this increase in fluid pressure to be communicated to the brake fluid distribution system.  The increase in fluid pressure in the second diameter section acts on the first diameter of the sleeve to again move the sleeve into engagement with the seat and interrupt communication through the sleeve.  During movement of the sleeve, the radial bore in the cylindrical body communicates any fluid which flows past the seat to the reservoir to avoid any fluid losses in the brake system.                                       -?-

Abstract: UNDERSPEED ACTUATOR FOR A HYDROSTATIC TRANSMISSION HAVING A SHUNT VALVE An underspeed actuator has a piston connected to a control means of a first pump driven by a prime mover and is movable between a first position at which the first pump is at minimum displacement and a second position at which the first pump is at maximum displacement.  The underspeed actuator has first and second actuating chambers at opposite ends of the piston and a biasing device urging the piston toward the first position.  The piston is movable between the first and second positions in response to pressure differential in said first and second chambers.  A signal device controllably develops first and second control signals in response to the operating speed of the prime mover.  First and second conduits deliver said first and second control signals to said first and second chambers, respectively.  A shunt valve is connected to the first and second conduits for passing fluid expelled from the first chamber to the second chamber in response to said flow of fluid exceeding a preselected flow rate.

Abstract: ABSTRACT OF THE DISCLOSURE      Four poppet valves are mounted in a common machined body which has a single inlet port, a pair of working ports and a pair of exhaust ports.  The body interior has four valve ports, two of which connect the inlet port to the two working ports and the other two connecting the working ports with the exhaust ports.  The housing also has identically sized guide supports and piston chambers for the poppet valves.  These may be chosen either as normally closed or normally open straight way valves in a variety of arrangements.  With each arrangement one or more pilot valves, either straight way, three-way or four-way, normally closed or normally open, may be connected to the piston chambers.  Thus, the valve system may be arranged to have a four-way function as controlled by a single normally closed three-way pilot valve, operate two independent fluid motors using two three-way pilots, or can be arranged for various other control functions.
