摘要： An improved pressure transducer to measure and indicate fluid pressure levels including a housing in which a piston assembly is movable in response to pressure changes, the housing being of a composite material of metal and plastic and having grooves therein, the piston having bosses formed thereon to be engaged within the grooves of the housing to prevent rotation of the piston. The transducer is also designed to facilitate grounding of an electrical contact assembly located within the housing. The external portion of the housing may be formed in a hexagonl shape to facilitate installation and removal of the unit.

摘要： A molded one-piece elastomeric anchor member for securing and apertured workpiece to a mating edge of a normally extending panel by means of a fastener. The anchor member has an elongated body comprising a pair of opposed arcuate wall portions defining a central bore for receiving a threaded shank of the fastener. The arcuate wall portions are interrupted by a pair of diametrically opposed living hinge gaps bridged by an arcuate web portion and a wedge-shaped portion, respectively. A cut-out, formed in the panel mating edge, is adapted to receive the anchor member therein. A flange section extends from each juncture of the web portion with the body so as to contact one side of the panel. The wedge-shaped portion defines a pair of cam shoulders adapted to snap outwardly and lock the anchor member in the cut-out after being manually compressed about its living hinges during insertion in the cut-out. Upon the threaded shank being inserted through the workpiece aperture and threaded in the central bore the anchor member is mechanically locked in the panel cut-out while the workpiece is secured to the panel mating edge.

摘要： A fluid pressure transducer having a hollow enclosure with an elongated tubular guide supported therein around which a tubular piston moves in response to fluid pressure forces acting on one piston end. A spirally-wound wire resistance coil on the guide is contacted by one end of a conductor carried by the movable piston to effectively charge resistance through the conductor and parts of the coil. The conductor is connected to one end of a metal spring which opposes piston movement due to pressure forces. An opposite end of the metal spring is connected to a terminal to transmit the resistance changes.

摘要： A coupler to connect spaced apart ends of a pair of aligned shafts of an odometer assembly, for example, a shaft supporting permanent or total mileage indicating wheels and another shaft supporting trip indicating wheels. The coupler has a generally tubular body with spaced side walls, each side wall having a slot to receive an adjacent shaft end which is configured with a pair of ground flats. The coupler also has an integral catch portion with a movable end portion adopted to pass between the spaced shaft ends when the coupler is inserted over the shaft ends and subsequently to expand outward for preventing removal of the coupler.

摘要： A shaft retainer or support means adapted to encircle a midportion of a shaft without need of axial travel over the shaft end portions includes a body portion having a circular channel means of more than about 180 degrees circumference so that the shaft can be inserted laterally into the channel means by slight flexing which is of sufficiently flexible material to allow this. The body portion also includes a second channel extending parallel to the circular channel and interconnected therewith for receiving a locking key member which axially moves along the shaft in the second channel means thereby completing a 360 degree engagement with the circumference of the midportion of the shaft. The preferred embodiment also includes axially locking means for the slideable key member to maintain it in a desired axial position within the second channel of the body.

摘要： In a vehicle having an internal combustion engine, it is usual to monitor the oil pressure of the engine's lubrication system to prevent damage to the engine in the event the oil pressure decreases to an unacceptable level. In this regard, a gauge or a warning light on the vehicle dashboard indicates when the oil pressure is low in response to a signal from an oil pressure transducer connected to the engine lubrication system. Herein is described an improved oil pressure transducer with a relatively easily crushable thin metal base housing member. The base housing portion is generally hollow and includes a threaded male support portion adapted to be received in a threaded aperture of the engine and fluidly communicated with the lubrication system. The base includes a molded wrenching portion of elastomeric material formed about the housing for contact by an installation tool. The molded wrenching portion is shaped on its outer circumference so as to facilitate rotation of the transducer by tool means without damage to the thin metal wall thereof.

摘要： A method for automatically controlling headlamps in response to windshield wiper controls is provided. A microcontroller senses the voltage levels of signals from a windshield wiper switch and a headlamp switch. If the microcontroller senses that the vehicle operator has turned on the windshield wiper switch, the microcontroller turns on the headlamps of a vehicle unless the windshield wipers are in intermittent mode or the operator of the vehicle has turned off the headlamps within a predetermined period of time.
