Preferably, the outer layer is formed using a filament winding process while the inner layer is molded of wear resistant urethane. Each boom section is formed by centrifugal molding a urethane tube then secondarily winding carbon fiber onto the exterior of the tube. The centrifugal force created by the rotating mold provides a bubble free urethane tube. The filament winding provides the hoop strength needed to withstand the internal pressures of the concrete pumping process.Type: ApplicationFiled: May 11, 2004Publication date: November 18, 2004Inventors: Martin G.

Patent number: 6626646Abstract: An in-line gas compression system, comprising a vehicle, preferably a truck, having a drive train, with a gas compressor mounted on the vehicle and driven by the drive train of the vehicle. The gas compressor is connected through a filter to a gas inlet and has a compressed gas outlet line. When a rotary screw gas compressor is used, an oil and gas separator is provided on the compressed gas outlet line, with the oil and gas separator being connected to return oil to the rotary screw gas compressor. The in-line gas compression system is typically connected into a gas pipeline system through the compressed gas outlet line, and is connected to a source of gas, for example a well at a well site.Type: GrantFiled: December 21, 2001Date of Patent: September 30, 2003Inventor: Robert C. Rajewski

Patent number: 6120258Abstract: A tire pump, which is adapted to be secured on a bicycle, includes an elongate mounting frame, a cylinder, a piston, a hinge member, and a lever. The mounting frame has first and second ends. The cylinder has a rear end pivotally secured to the second end, and a front end spaced apart from the rear end and disposed to be proximate to the first end. The piston is disposed to reciprocate within the cylinder so as to pump air out of an outlet in the rear end to inflate a bicycle tire. The cylinder further has a piston rod with a fixed end secured to the piston in the cylinder and a coupling end extending axially and outwardly of the front end. The hinge member includes a fixed knuckle member and a movable knuckle member. The fixed knuckle member is disposed on the coupling end.Type: GrantFiled: January 27, 1999Date of Patent: September 19, 2000Inventor: Pai-Chou Chen

Patent number: 6004107Abstract: A water removal apparatus is provided which enables the user to remove water from a wet surface, such as a back yard lawn or sports field. The apparatus includes a frame structure, a press member, and a water removal system. The press member is rotatably mounted to the frame structure. The press member has openings through which water passes. The water is temporarily collected within the press member as the press member is rolled across the wet surface. The water removal system removes the water from the press cylinder and places it in a storage member. The water may then be transported to a different area, and the storage member drained.Type: GrantFiled: June 27, 1997Date of Patent: December 21, 1999Inventor: Gary L. Johnston

Patent number: 5635805Abstract: A hybrid vehicle has a clutch between the engine and the rotational electrodynamic unit. A driving energy transmission mechanism is provided between the clutch and the rotational electrodynamic unit for transmitting driving energy to an appliance such as an alternator. When driving the engine, the clutch is closed by a clutch controlling unit, and the engine makes the rotational electrodynamic unit function as a generator to operate the appliances. When the engine is stopped, the clutch is opened by the clutch controlling means, and the rotational electrodynamic unit is caused to operate as a motor to operate the appliances. In the system where the appliances are driven by the engine, the appliances are kept being operated even after the engine stops. This structure is applicable to both a series hybrid vehicle and a parallel hybrid vehicle.Type: GrantFiled: June 26, 1995Date of Patent: June 3, 1997Assignee: Toyota Jidosha Kabushiki KaishaInventors: Ryuji Ibaraki, Yutaka Taga, Yoshihiro Kawashima
