Patent number: 4221446Abstract: An electrical connector assembly (800) in which two mateable housings (200, 500) each have electrical contacts (100, 400) mounted therein. Each contact has a forward mating portion with a plurality of axially aligned wires (120, 420), each wire having an acutely angled forward end surface (122, 422). The axially aligned wires of each contact are surrounded by a shroud or sleeve (130, 430) which extends around the wires and forwardly of the end surfaces to protect them and allow the contact to be inserted into the housing from the rear through a rear-mounted grommet (300, 600). The sleeve (130) on the one contact has a larger diameter forward end than the sleeve (430) on the other mating contact to allow the sleeves to interfit together in telescoped relationship when the housings and contacts are mated. The housing (200) having the contact with the larger diameter sleeve (130) has a contact retention system which includes a forward stop (214) to captivate the contact by engaging the forward end of the sleeve.Type: GrantFiled: October 2, 1978Date of Patent: September 9, 1980Assignee: The Bendix CorporationInventors: Paul D.

Patent number: 4125374Abstract: A wide range combustion mixture air/fuel ratio sensor in which an electrochemical cell supplies hydrogen gas to a palladium sensor element at a rate regulated by the output of a Wheatstone bridge circuit incorporating the sensor element. This generated hydrogen gas combines with any oxygen present in the exhaust gas through catalytic action and also maintains the level of absorbed hydrogen, and therefore the electrical resistance of the palladium sensor element, at a preselected value. The magnitude of the current applied to the electrochemical cell necessary to maintain this balance is a measure of the combustion mixture air/fuel ratio.Type: GrantFiled: November 21, 1977Date of Patent: November 14, 1978Assignee: Bendix Autolite CorporationInventors: James D.

Patent number: 4109990Abstract: An electrical connector assembly in which the electrical connectors are capable of being quickly and easily coupled and decoupled with mechanism for preventing accidental decoupling of the connector through vibration. The coupling and decoupling is accomplished by a coupling nut mounted to one electrical connector, with the coupling nut having a screw thread adapted to receive a screw thread on a second connector. The connector assembly is adapted to remain coupled to said first housing by a spring mounted to the coupling nut and engaging ratchet teeth carried on an edge of the housing. The ratchet teeth are more steeply angled on the leading edge engaged during decoupling and more gradually angled on the leading edge during coupling, allowing for an ease in coupling and a greater resistance to decoupling.Type: GrantFiled: May 26, 1977Date of Patent: August 29, 1978Assignee: The Bendix CorporationInventors: Clifford R. Waldron, Carl L. Knapp

Patent number: 4092854Abstract: A multi-axis load cell of the type adapted to generate signals corresponding to each of the various force and moment components exerted on the load cell is disclosed, comprised of a hub and a housing interconnected by three flexure arms, each flexure arm fixed at one end to one of the hub or housing and at the other end to a beam flexure element fixed to the other of the hub or housing. Each flexure beam is designed to be readily deflected in directions aligned with its respective flexure arm but offers substantially greater resistance to deflection in other directions, so that a centering bias force is provided without restricting the bending deflection of the flexure arms relied on to measure the force and moment components.Two sets of displacement transducers are provided, each set consisting of three transducers, with the first set arranged in pinwheel fashion about the load cell axis to measure the XY displacement components and torsional about the load cell axis.Type: GrantFiled: April 20, 1977Date of Patent: June 6, 1978Assignee: The Bendix CorporationInventors: James L. Henry, Carl F. Ruoff, Jr.
