Title: Seat supporting assembly and wheelchair including same
Inventor: DUGAS ERIC
IPC: A61G5/10
Filed: 2006-10-17
Abstract: A seat supporting assembly (24) for supporting a seat (18), the assembly comprising a base (25) including a substantially elongated guiding rod (58), a seat support (36), a seat support-to-base linking member (56) pivotally coupled to the seat support (36) and sliding on the base guiding rod (58), a substantially elongated tilting member (60) having a guiding groove (66) and being pivotally attached to the seat support (36) and to the base (25). An actuating assembly (44) is coupled to the base (25) and includes a motion transmitting member (68) mounted within the guiding groove (60). The force from the actuating assembly moves the tilting member (60) according to the geometry of the guiding groove (66), which causes the seat supporting assembly (24) to move between tilted and upright configurations by pivoting the tilting member (60) relative to the seat support (36) and the base (25) and substantially simultaneously moving the seat support-to-base linking member (56) longitudinally relative to the guiding rod (58). The assembly is designed to maintain the location of the center of gravity of a user as the seat tilts rearwardly by automatically moving the seat forwardly during tilting. The guiding groove (66) in the tilting member (60) may be curved such that the tilting motion occurs with a constant angular velocity The seat assembly is particularly useful for wheelchairs.

IPC: B60W50/06
Filed: 2008-10-09
Abstract: A clutch control apparatus for a vehicle provided with a hydraulic clutch in the middle of a power transmission path between an engine and a drive wheel.  Before the clutch of the vehicle is brought into an engagement state, intermittent hydraulic pressure Y is applied to the clutch while maintaining the clutch in a disengagement state, and thereafter a predetermined hydraulic pressure is applied to the clutch to bring it into the engagement state. A solenoid valve is provided to control hydraulic pressure supplied to the clutch. Before the clutch is brought into the engagement state, a pulsed drive current D is supplied to the solenoid valve.  The clutch control apparatus so configured suppresses a motion delay at the time of engaging the clutch, thereby allowing a quick and smooth start and shifting of the clutch.

Abstract: A process for calcined-gypsum production which attains a reduction in the amount of water to be mixed and does not prolong setting time. A raw-material gypsum is calcined after a carboxylic acid is incorporated thereinto, whereby calcined gypsum can be obtained which necessitates a smaller amount of water to be mixed therewith and needs no prolonged setting time. Even when recycled gypsum, which leads to an increase in the amount of water to be mixed, is used in a large amount as a raw material for gypsum, the calcined gypsum produced by the process is reduced in the amount of water to be mixed therewith and needs no prolonged setting time. Consequently, ordinary gypsum boards can be produced without lowering the productivity thereof.

Filed: 2007-03-28
Abstract: The invention is based on the principle relating to the formation of cyclones to produce electrical power that is environmentally-friendly, clean, inexhaustible and abundant to the extent that current consumption is insignificant. The invention makes use of the acceleration imparted by the earth to the fluid that passes transversely through the latitudes, directing same to the closest pole. The invention comprises a duct which can be straight, in the form of a doughnut (toroid) or have any geometrical shape, conforming to the principle that, when level in one of the hemispheres, the fluid is directed towards the pole in the case of the straight duct and rotated in the direction of rotation of the earth in the case of the doughnut. The initial movement is forced and subsequently accelerated and sustained by the rotational movement of the earth. As a result of said movement, the fluid drives the turbines which produce electricity.

Abstract: Carbonyl compounds generated and accumulated in the peritoneal dialysate can be inactivated or eliminated by a carbonyl compound-trapping agent such as aminoguanidine. Carbonyl compounds generated during sterilization and storage of the peritoneal dialysate can be eliminated by pre-contacting with the trapping agent. Further, it is possible to eliminate carbonyl compounds transferred from the blood to the peritoneal cavity of the patient during peritoneal dialysis treatment, by adding the trapping agent to the peritoneal dialysate or by circulating the fluid through a carbonyl compound-trapping cartridge. Intraperitoneal protein modification by carbonyl compounds is inhibited by the present invention, thereby sufficiently reducing peritoneal disorders associated with peritoneal dialysis treatment.
