Each valve unit (26) has a valve body (48) and a shiftable piston-type sealing member (56).Type: ApplicationFiled: February 27, 2003Publication date: October 7, 2004Inventors: Bradford T.

Publication number: 20040194978Abstract: A fire protection and extinguishing device for a water-conducting domestic appliance. When a malfunction occurs that in the appliance that could potentially result in a fire, the device protects the appliance from further damage, prevents the danger of a fire starting and can extinguish a fire, which has already started. The device includes a fault current circuit breaker, which will disconnect the electric supply to the appliance, when a fault current occurs. The device further includes a gas sensor and a water sprinkler, which will disconnect the electric supply to the appliance and activate the water sprinkler, when a specific amount of control gas occurs in the appliance.Type: ApplicationFiled: December 18, 2003Publication date: October 7, 2004Applicant: BSH Bosch und Siemens Hausgerate GmbHInventors: Helmut Jerg, Stefan A.

Publication number: 20040194986Abstract: It is an object of the present invention to provide a reciprocating power tool having a further improved power transmission mechanism for converting a rotating output of a driving motor into linear motion in the axial direction of the tool bit. According to the present invention, a representative reciprocating power tool may comprise a tool bit, a driving motor, a power transmission mechanism. The power transmission mechanism converts a rotating output of the driving motor into linear motion in the axial direction of the tool bit. The power transmission mechanism includes an internal gear, a planetary gear and a power transmission pin. The internal gear is allowed to rotate by a predetermined degree in relation to a load applied to the tool bit. As the result of rotation of the internal gear, the relative position of the power transmission pin is changed with respect to the point of engagement between the internal gear and the planetary gear.Type: ApplicationFiled: January 9, 2004Publication date: October 7, 2004Applicant: Makita CorporationInventor: Hiroki Ikuta
