Abstract: A resilient suspension system for the front wheel of a bicycle includes a steering column supported on the frame of the bicycle and supports a handle bar at the upper end and a resilient suspension assembly at the opposite end. The suspension system includes a pair of main forks which are carried by a crown member mounted on the bottom of the steering column and the forks are displaced to the rear of the longitudinal centerline of the column. A subsidiary fork assembly is mounted within the steering column and extends generally along a common longitudinal axis to cooperate with the main forks to support the front wheel of the bicycle in a resilient fashion. The subsidiary forks and the main forks are interconnected by a pair of pivotal links which will permit relative movement between the main forks and the subsidiary forks in response to surface irregularities and transmit such movement to a compression assembly disposed within the steering column.

Abstract: The invention relates to a rotary hydraulic pump comprising a housing defining a generally cylindrical pump chamber between axial end walls. The chamber is bounded radially by a mainly cylindrical wall interrupted by two recesses constituting inlet and outlet ducts of the chamber. A shaft passes axially through said end walls and the part of the shaft which is located within the chamber is constituted as a crank. A cylindrical pumping sleeve surrounds the crank and is adapted as the crank rotates to move eccentrically within the chamber and so that the external cylindrical surface of the pumping sleeve co-operates with the mainly cylindrical surface of the radial wall of the chamber whereby a crescent-shaped clearance between said surfaces rotates around the chamber and liquid introduced through the recess constituting the inlet duct is impelled around said chamber towards the recess constituting the outlet duct.
