  • Patent number: 4732671
    Abstract: A separating device for separating a pair of immiscible components from a fluid mixture, such as separating water from a diesel fuel oil/water mixture, includes a housing and a filter cartridge mounted on the housing such that the filter cartridge is oriented substantially horizontally. The housing includes an inlet fitting, an outlet fitting, and a sump for receiving the fluid component separated from the mixture. Because of the orientation of the housing, the coalesced water or heavier component of the fluid mixture tends to collect in the lower portion of the filter cartridge and drains into the sump, where it may be drained periodically. The lighter component or fuel oil is communicated to the outlet port or fitting.

  • Patent number: 4733216
    Abstract: In microprocessor based control systems wherein several analog sensors are used to generate control signals of N bits, the system herein generates a digital signal having an N+1 bit resolution of the information. The N+1 bit resolution is generated from an N bit A/D converter by means of a network changing the reference voltage input to the A/D converter by an offset voltage which is a function of the least significant bit position. The network, in the absence of a control signal, generates a first range of reference voltages and in the presence of the control signal generates a second range wherein the limit voltages are changed by the offset voltage. The microprocessor reads and stores each N bit digital word from the same sensor and under the command of the control signal, sums the two digital words and the result is an N+1 bit digital word.

  • Patent number: 4732677
    Abstract: A fluid filter is disclosed which consists of a stack of discs which are formed form an air laid, nonwoven batt of randomly arrayed fibers. The batt includes a thermoplastic component to give the disc a self-supporting stiffness when molded. Each of the discs have radially extending contaminant collecting surfaces on the opposite sides thereof, and each have axially offset portions circumscribing the inner and outer diameters of the disc. Alternate disc in the stack are inverted, so that the axially offset portions on the inner and outer circumferences of the disc are brought into registration with one another. Accordingly, radially extending flow paths are defined between the disc to communicate fluid toward and away from the contaminant collecting surfaces. Ribs are provided on the contaminant collecting surfaces to maintain separation of the disc under dynamic flow conditions.

A ring-shaped stator is secured to the housing and is concentric and between the legs of the U-shaped rotor. The stator is formed by a continuous strip of magnetic material wound and laminated in a toroid and having helical windings therearound. On the inside of the legs of the rotor are mounted a plurality of permanent magnets forming the poles of the motor. Radially opposite magnets are of the same polarity. Control of the switching of the current through the windings is by means of Hall Effect devices sensing the change in polarity of a ring shaped magnet means having the same number of poles as does the permanent magnets.

  • Patent number: 4729285
    Abstract: A brake booster (42) having a hub (78) with control valve (56) located therein. The control valve (56) has a plunger (106) connected to an output rod (62) through a reaction disc (60) and to a brake pedal. A sleeve (112) which surrounds the plunger (106) is urged toward a shoulder (110) on the plunger (106) by a first resilient member (112). An input applied to the brake pedal moves the plunger (106) to allow air to enter into the booster (42) and create an operational pressure differential across a movable wall (50) to develop an output force. The output force is carried through the reaction disc (60) and a reaction force is carried through the plunger (106) to balance the input force. On termination of the input force, the reaction force and first resilient means (126) move the plunger (106) to define a gap between an annular seat (102) and a poppet (117) member to allow vacuum to evacuate air from the booster (42).

  • Patent number: 4729607
    Abstract: A dual circuit brake valve is provided with a delivery differential control mechanism which controls the differential between the delivery pressures of the primary and secondary braking circuits. The delivery differential control mechanism includes a spring retainer which is mounted on the end of the stem of the relay valve and which receives a spring-biased plunger. The plunger engages with the actuating member during the brake application to thereby transfer the force of the spring to the relay member and therefore to the valve members of the secondary circuit. This transfer of the spring force reduces the crack open pressure of the valve members controlling communication through the secondary circuit, to thereby reduce the differential between the pressures generated and the primary and secondary circuits.
