摘要:
A threaded assembling means to be tested is mounted between a rotatable annular plate and a stationary endpiece respectively carried by one end of a generally tubular fixture and the corresponding end of an extensometer gauge, the opposite ends of which are screwed to a common base member. Said gauge consists of a hollow cylindrical body, the internal space of which is filled with a liquid and communicates with an external capillary tube.

A telescopic hydraulic shock-absorber comprises inner and outer cylinders provided at their head and foot ends with respective closure members formed with conical bearing surfaces for selfcentering of said cylinders. The annular head closure member of the inner cylinder guides the rod of a piston through which are arranged, for each direction of motion, two valves opening at different pressures. The annular foot closure member of the inner cylinder carries coaxially arranged valve means, controlling selectively the flow of make-up liquid to and from said outer cylinder.

Modern high-performance combustion engines have the drawback of continuing to run at idling speed during a certain period when switched off. A known method used to avoid this phenomenon consists in shutting off the arrival of gasoline into the idling circuit of the carburetor. According to the invention when the internal combustion engine is fed by a dual-body carburetor, it is provided with only one member for stopping the feeding with fuel on only one of the two idling tubes of the carburetor and actuated simultaneously with the switching off of the engine ignition circuit.

A regulator provided with an inertia-block resiliently connected to a slidable pressure-responsive member controls automatically the feeding of fuel to the idling jet of a carburetor, in response to pressure variations in the inlet manifold of an internal-combustion engine. Consequently air pollution by unburnt fractions of the exhaust gases at idling speed and during deceleration is substantially prevented.

The invention has for its object a device for drilling sheet metal. According to the invention, the pressure with which the drill is applied on the sheet is determined by a resilient member which is located between two drive members solid in rotation but not in translation and which are mounted in a sleeve which, during operation, rotates and slides in a fixed body of the device.
摘要:
A device for the injection of secondary gases into the conduit for the intake of the gaseous fuel mixture of an internal combustion engine, comprising a nozzle mounted in said conduit the upstream mouth of which joins the said conduit in which it fits, and the downstream mouth of which is located in the said conduit with a certain clearance, forming a free annular space between said nozzle and said conduit, and duct for the supply of the said secondary gases, opening into said annular space, and communicating with a supply source of said secondary gases.

Assembling support for fixing two assemblies in desired positions and directions relative to each other in view of subsequent joining of the said assemblies to other parts or to each other. According to the invention the fixture comprises a tube at each end of which is welded a ball member fixed with a plate provided with means for temporarily fastening the said assemblies respectively to the plates.
