Abstract: The invention relates to a dosing pump comprising a chamber, an inlet valve located in an inlet pertaining to said chamber, and an outlet valve located in an outlet pertaining to said chamber. The chamber is divided into two partial chambers (2, 18) by a separating means. Said separating means comprises a separating valve (38) which opens in the direction of conveyance and which connects the partial chambers (2, 18). The separating means can be moved back and forth in the direction of conveyance and is connected to a drive device for this purpose. When the separating means is moved in the direction of conveyance, dosing liquid is sucked in via the inlet valve (6) and is simultaneously discharged via the outlet valve (28). This process is carried out smoothly and continuously.

Abstract: A door checking apparatus for an automobile comprising an array of needle bearings held in contact with a bearing surface comprising axially oriented grooves, by means of a resilient energy storage device; a cylindrical cage coaxially adjacent the bearing surface and comprising an axially oriented array of slots arranged to retain the needle bearings; means to impart rotary motion to the cylindrical cage to cause the needle bearings to move relative to the bearing surface to create a torque reaction in response to deflection of the resilient energy storage device as the needle bearings move into and out of the grooves; means to transmit the imparted torque from the bearing surface into an appropriate structure.

Abstract: The friction gear disclosed includes driven and driving shafts whose rotational axes are parallel to but spaced from each other. One of the shafts has an axial bearing surface mounted on its facing end. The other shaft includes means for mounting at least two rollers that are spaced from the rotational axis of the one shaft and that bear against the axial bearing surface. While several different embodiments are disclosed, the means for mounting and aligning the rollers holds each of the rollers such that its rotational axis is directed toward and intersects a straight line which extends parallel to the rotational axes of the shaft and which lies in a plane determined by the two rotational axes of the shafts.
