Patent number: 4745707Abstract: A plant pot assembly characterized by a container covered by a substantially impermeable cover such that water may be drawn upwardly through a capillary space between the covering and the container to irrigate a plant disposed within the container. The assembly also includes an outer enclosure which distills irrigation water, and which further aerates the growing medium within the container by forcing vapor saturated air into the medium. Due the combination of a capillary pumping action and an evaporation/condensation cycle, the plant pot assembly provides continuous irrigation for a plant at most ambient temperatures.Type: GrantFiled: June 4, 1986Date of Patent: May 24, 1988Inventor: John Newby

Patent number: 4745709Abstract: A building drain gutter has a flexible liner disposed in the trough of the gutter and connected in sealed relationship with upper edges of the gutter, the liner being loosely disposed within the trough and conforming to its configuration between the edges. A conduit is connected into the trough and communicates with an air compressor which when activated forces the liner to balloon upwardly out of the trough to remove debris which has accumulated thereon. The liner is a relatively thin plastic film such as vinyl. A downspout connected into the gutter communicates through a hole in the liner which is sealed with the trough about the hole. The liner acts to channel water to the downspout, yet can be lifted by the compressed air when necessary.Type: GrantFiled: July 10, 1987Date of Patent: May 24, 1988Inventor: Douglass M. Johnson

A central variable capacity hydraulic fluid pump supplies the steering system and a secondary consuming device via separate respective compensated pressure maintaining valves. The steering system and secondary consuming device are controlled by respective load report lines which are brought together at a changeover valve which is operative to permit the higher reported pressure to be delivered to a volume governor for the pump. Upon the secondary consuming device entering a neutral condition or a fluid loss condition, the changeover valve moves to block the load report line to the secondary consuming device; and a control circuit, including a branch line from the feed line to the steering system, maintains a higher pressure in the load report line of the steering hydraulic circuit than in the line of the secondary consuming device.Type: GrantFiled: April 15, 1986Date of Patent: May 24, 1988Assignee: Mannesmann Rexroth GmbHInventors: Wolfgang Krausse, Norbert Mucheyer

Patent number: 4745749Abstract: A Stirling engine design which is solar powered is disclosed. A solar receiver converts solar radiation to thermal energy, which is stored in a storage chamber. The engine includes a displacer chamber with a displacer piston which divides the chamber into hot and cold subchambers, the hot subchamber being heated by the storage chamber. A mechanism is provided for cooling the cold subchamber. The engine also includes an alternator chamber with an alternator piston which divides the chamber into working and bounce subchambers, the working subchamber being in fluid communication with the cold subchamber of the displacer. The working fluid circulates through the cold subchamber and the working subchamber and obtains heat from the storage chamber. The working fluid is displaced by the displacer piston to drive the alternator piston, and work output is obtained from the alternator piston.Type: GrantFiled: October 7, 1986Date of Patent: May 24, 1988Assignee: New Process Industries, Inc.Inventor: Glendon M.

Patent number: 4745750Abstract: An auxiliary-energy-supplied brake slip control system of a vehicular hydraulic brake system with a brake-pedal-operable master cylinder arrangement (12) and with auxiliary energy supply into the working chamber (16) of the master cylinder. The master cylinder piston (23) portion facing the working chamber (16) is enclosed by a sleeve (58) which is longitudinally displaceable with respect to the master cylinder piston (23) and the master cylinder bore (63). The master cylinder piston (23) having radially extending projections or a collar (66) which, in the brake release phase, rests at the working-chamber-side front face of the sleeve (58) and moves the same back into its initial position. The booster-side front face of the sleeve (58) confines an annular space or a chamber (69) provided in the master cylinder housing and communicates with the booster chamber (21) by way of a pressure line (64).Type: GrantFiled: September 18, 1986Date of Patent: May 24, 1988Assignee: Alfred Teves GmbHInventors: Juan Belart, Wolfram Seibert, Norbert Ocvirk, Juergen Schonlau, Guenter Trach

Patent number: 4745751Abstract: The master cylinder (10) comprises a housing (12) having a longitudinal bore (14), a housing end (16) enclosed by a bearing member (18) which retains a sleeve member (20) within the bore (14), a reservoir (70) mounted on the housing (12) and a pair of pistons (30, 40) received slidably within the bore (14), one piston (30) extending through an end (24) of the sleeve member (20). The one piston has an end (32) which provides seating for a fast fill valving mechanism (110). The fast fill valving mechanism (110) comprises a piston support guide (120) supporting a fast fill seal (150) and seal retainer (160) between the support guide (120) and the surface (23) of the sleeve member (20). The seal retainer (160) engages one end (142) of a spring (140), the other spring end (143) located at the end (32) of the piston.Type: GrantFiled: February 3, 1987Date of Patent: May 24, 1988Assignee: Allied CorporationInventor: Robert F.

Patent number: 4745752Abstract: An exhaust gas turbine type supercharger in which a casing of a turbine is divided into two chambers along a flow direction of the exhaust gas to form an open scroll and a closed scroll. The open scroll feeds the turbine with the exhaust gas over a full operational range of the engine. The closed scroll is opened to increase a flow rate of the exhaust gas to the turbine when the supercharged pressure is high as in a high load/high speed operation of the engine. A port is formed through a partitioning wall between the open scroll and a downstream exhaust gas passage of the turbine and an opening/closing valve is interposed thereat to thereby bypass the exhaust gas to a downstream portion of the turbine with the port being opened, when the supercharged pressure becomes high.Type: GrantFiled: November 1, 1985Date of Patent: May 24, 1988Assignee: Hitachi, Ltd.Inventor: Satoshi Suzuki

Patent number: 4745755Abstract: A supercharger associated with an internal combustion engine has a rotatable shaft on which there is mounted an electric rotary machine operable as an electric motor or an electric generator. When the motor vehicle driven by the internal combustion engine is braked so as to be decelerated, the rotary machine is operated as the generator to enable the supercharger turbine to act virtually as a load on the exhaust manifold of the engine, thereby increasing the force of an engine brake. When the motor vehicle is to be further decelerated, the rotary machine is operated as the motor to reverse rotation of the turbine impeller for further increasing the load on the exhaust manifold to add to the engine brake force. While the rotary machine is being operated as the generator, electric power generated thereby is used to charge a battery. When the rotary machine is operated as the motor, the stored electric power is supplied from the battery to the rotary machine.Type: GrantFiled: July 23, 1986Date of Patent: May 24, 1988Assignee: Isuzu Motors LimitedInventor: Hideo Kawamura

Patent number: 4745756Abstract: A HDR closed loop geothermal steam generating system comprises of three large vertical bores driven in solid rock to a depth of 2 to 3 miles and terminating in an enlarged bottom chamber from which a series of horizontal tunnels radiate. A plurality of small bores are then driven down from each horizontal tunnel to a depth where the rock temperature is high enough for steam generation. A steam generating chamber is placed at the foot of each small bore to which feed water is supplied. Steam is piped from the steam generating chambers to a common header in each horizontal tunnel. Each header feeds into a steam riser in one of the large vertical bores which conveys the steam to the surface. Steam condensate is recycled as feed water without the need of pumps.Type: GrantFiled: October 6, 1987Date of Patent: May 24, 1988Inventor: Robert Sederquist
