Title: Vehicle oil sump drain or filler plugs with integral valves - involving heat and oil resistant rubber seals or plastic bodies
Inventor: JEANGUENIN CLAUDE
IPC: F16L19/00
Filed: 1976-11-08
Abstract: Plugs for draining or filling lubricant reservoirs comprise a hollow threaded coupling incorporating a coaxial mushroom head valve located on a bevelled seat by a spring loaded rod. Thrust on the rod from a cross member on a suitable hose coupling overcomes the valve spring to allow draining or filling. A variation comprises a banjo coupling allowing full bore flow through a hollow stud coupling and lateral draining/filling via a lateral spring loaded valve in the neck of the banjo coupling. The valve incorporates a heat-and oil-resistant 'O' seal of e.g. fluorinated rubber. The valve and plug body are pref. sized to fit conventional sump plug outlets in car engine sumps, gearboxes, rear axles, etc., may be moulded of material oil-resistant up to 200 degrees C e.g. polyimide or glass-filled polyamide. Facilitates draining and filling without use of elevating ramps or pits.

Title: Thermally operated fluid flowmeter - measures power required to maintain temperature gradient in fluid stream
IPC: G01F1/684
Filed: 1977-02-28
Abstract: The appts. measures the flow of fluids by thermal means. A flow meter of the heated conduit type is operated in a constant temperature mode to produce two output signals, one proportional to the differential temperature between two points in the fluid and the other proportional to the power required to maintain that temperature differential constant. The power is a measure of the mass flow and the heat capacity of the fluid. Consequently, by monitoring the power input to the flowmeter, the mass flow rate is determined.

Title: Cylindrical workpiece sorter and feeder - has adjustable piston actuated sensor on guide bar to accommodate wide size range
IPC: B07C5/02
Filed: 1977-06-14
Abstract: The unit controls the supply of workpieces to a machine tool and ejects those which are not within the given limits of length and diameters. It is suitable for sorting out cylindrical parts with smaller ends. The baseplate carries brackets for a pivoted stud which supports the escapement plate, abutment holder and locking lever. The workpiece reaches the escapement by contacting the abutment, and the deflection of plate frees the path to the sensors. Control cylinders press the tilted plates against the abutment pins to close the sensors so that the danger end of the workpiece is gripped when cylinder retracts the sensor. Opening of both sensors leads to the turning over of the workpiece in the sensor which gripped it previously.

Title: Telephone exchange connector for analogue and digital signals - has primary multiplexer and demultiplexer connected via bus to second multiplexer-demultiplexer group
Inventor: YVES
IPC: H04Q11/04
Filed: 1977-11-03
Abstract: The network connection system for a central exchange is able to multiplex both analogue and digital signals as may appear in a mixed system using 2/4 lines. The network uses a primary multiplexer and demultiplexer connected to both transmission and reception lines and also via a bus to a second multiplexer/demultiplexer group to which the corresponding multiple access points are connected. This forms a direct route and two further routes via a coder and decoder. The switching gates of the groups are controlled in time such that the routes carry either analogue or digital signals.
