Title: Well tubing mandrel with welded side pocket housing
IPC: E21B23/03
Filed: 1971-08-30
Abstract: A high pressure mandrel for insertion in a well tubing string has an oval cross-section intermediate circular pin or box-ends, and a side pocket housing for a valve is welded to the mouth of a window cut into the minor side of the intermediate section.

Title: Fuel flow control system for internal combustion engine - has piston damper with resistance decreasing as stroke increases
IPC: F02D1/04
Filed: 1975-10-03
Abstract: The fuel flow from the pump (10) is controlled by the lever (12) which in turn is controlled by the centrifugal governor (13, 14) so that increasing speed reduces the flow. The lever (12) is also connected by the tension spring (15) to the rod (16) of the piston damper (17). The piston damper is operated by the lever (23) which is connected to the vehicle accelerator pedal. Fluid is supplied through the non-return valve (25) into the cylinder (18). When the accelerator pedal is initially depressed the motion of the piston is opposed by the fluid which can only escape through the hole (26) and a small groove in the piston (17). When the piston uncovers the hole (26) the flow resistance decreases sharply.
