One end of the telescopic hollow spindle is fixed on the housing. With its other end, the telescopic hollow spindle cooperates with a plunger containing a passage opening for lubricant. The telescopic hollow spindle has a lubricant passage channel in which at least one check valve is arranged on the inlet side. The telescopic hollow spindle alternately carries out setting strokes of different lengths that increase or reduce the length of the spindle. The setting strokes are coordinated with each other so that with a setting stroke of the telescopic hollow spindle increasing the length of the spindle, a preset amount of lubricant displaced by the movement of the plunger enters the lubricant passage channel through the opening check valve.Type: GrantFiled: October 18, 2001Date of Patent: August 5, 2003Assignee: perma-tec GmbH & Co. KGInventors: Michael Weigand, Armin Brand, Bernd Scheit, Thomas Hildenbrand

Patent number: 6503063Abstract: A portable air moving apparatus for providing personal air cooling includes a container with open top and supported by plural wheels attached thereto. The container encloses electrical components including a battery, a radial flow air moving device, and a switch. These components are interconnected by electrical conductors such that the switch can make and break a circuit for driving the air moving device with the battery. A removable container lid provides an aperture for receiving an air exhaust from the air moving device which is then directed toward an individual to provide cooling. The container lid is adapted for being set to allow air flow into the container so as to feed the air moving device.Type: GrantFiled: March 29, 2001Date of Patent: January 7, 2003Inventor: Willis Brunsell

Publication number: 20030002999Abstract: A compressor with a built-in electric motor has a compression mechanism and the built-in electric motor which are housed in a container. A suction port, a discharge port, inner and outer electric connection parts, and-mounting legs of the container are provided on the same side of a body of the container. A bearing part for supporting an end of a driving shaft for driving the compression mechanism is formed on an end wall integral to -the body of the container, where the end of the driving shaft to be supported by the bearing part is located in the direction opposite to the compression mechanism and the driving shaft is connected to the built-in electric motor. In addition, a pumping mechanism is provided in a pumping chamber opened to an external surface of the end wall and is connected to the end of the driving shaft in the direction opposite to the compression mechanism. The opening of the pumping chamber is closed by a closing member.Type: ApplicationFiled: June 10, 2002Publication date: January 2, 2003Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Tsutomu Sakurabayashi, Masahiko Makino, Yoshifumi Abe

Patent number: 6481983Abstract: A handless or footless operation of an electrical automatic water flow control apparatus for turning water on and off without touching the faucet lever of a faucet. The electrical water flow control apparatus is installed in line between the water shutoff valves from the wall and the water supply lines that descend from a faucet. The flow control apparatus includes a housing which houses a pair of solenoid operated valves. Each solenoid operated valve has an inlet port and an outlet port, where the ports are protruding through a wall of the housing. The inlet ports are connected to the hot and cold water shutoff valves by flexible hoses. The outlet ports are connected to the water supply lines from the faucet by flexible hoses. The electrical flow control apparatus further comprises an elongated bar switch actuator and a transformer which supplies power to the solenoid operated valves.Type: GrantFiled: June 14, 2001Date of Patent: November 19, 2002Inventor: Gerald W. Miller

Patent number: 6468057Abstract: A free piston pump has a pump housing defining a chamber, and a free piston located within the chamber. The free piston defines one (or more) pumping chamber(s). Each pumping chamber receives fluid from one (or more) inlet port(s) and delivers fluid to one (or more) outlet port(s). The pump has an electromagnetic drive system for moving the free piston within the chamber. Check valves or porting can be used to admit fluid into the pumping chamber(s) and release fluid from the pumping chamber(s). The pump can use three types of bearings and two types of seals. The pump has small heat leakage to the fluid being pumped. The pump is insensitive to cavitation, and has the potential for long-life. The pump has low leakage to the ambient environment.Type: GrantFiled: September 13, 2000Date of Patent: October 22, 2002Inventor: Douglas S. Beck
