A method and an apparatus for measuring the wall thickness of a plastic article, particularly of a hollow rotation-symmetrical plastic article. According to the method, the wall of the plastic article is subjected to infra-red radiation and the intensity of, e.g., the continuously transmitted radiation is measured at preselected points, said intensity being a function of the wall thickness to be m...

Flexible polyurethane foam having reduced tendency to form burning embers when it is ignited and burned is provided by incorporating into the reaction mixture before foaming a ketone or benzaldehyde. In a preferred embodiment, flexible polyurethane foam of increased flame retardance is provided by also incorporating a flame retardant into the reaction mixture before foaming.

The toe abutment member comprises a jaw unit pivotally mounted on the ski and consisting of two lateral arms adapted to cooperate with the front portion of the ski boot in order to maintain the boot in the axis of the ski, and a resilient device housed within the body of the abutment member for locking the arms in the boot-retaining position with a predetermined stiffness of release. The toe abutm...

The present invention relates to an indicating device for the setting of the initial squeezing of the elastic member of the release mechanism for a safety ski binding. This device is characterised in that the index or indicator (8) is mounted on the setting member itself (6) or on an intermediate part and is fixed in the correct position corresponding to the previous calibration.

The axis of rotation of a plate which carries the heel-holding member of a ski binding is forwardly inclined at an angle approximately between 8 DEG and 20 DEG with respect to a vertical axis perpendicular to the top ski face. This angle of slope is close in value to the forward slope imposed on the skier's tibia by the shape of the ski boot. The top surface of the rotary plate nevertheless rema...

In addition to a boot-retaining jaw unit controlled by a spring having an adjustable degree of stiffness, the safety ski binding is fitted with a force transducer for detecting the effort exerted by the spring on the jaw unit and delivering a signal which is a function of the effort thus detected to an electronic display device of the digital type. The display device is supplied via a normally-ope...

PURPOSE:To prepare water-impermeable foamed polyolefin molding by the bead method by a method wherein a heated, fused foamed-bead molding is left between dies for some time when the resin keeps fluid. CONSTITUTION:Foamed beads are filled in the dies, heated and fused. Then, when the temperature is high and the resin keeps fluid, the molding is let alone between the dies (in this case, preferably, ...

In an electro-mechanical control system for controlling all the movements of one or more slides on a single workhead grinding machine, a programmable controller is interfaced with a digital-to-analog converter or feed control which in turn controls a drive motor that is directly connected to a screw actuator means that directly controls the movements and positions of a slide. The positioning accur...

The unit comprises a cylinder housing (8) and a piston (7), which latter is axially movable out of the open end (13) of the cylinder housing (8), as well as an annular seal (9) in an annular groove (10) in the cylinder housing (8). The radially outer wall (22) of the annular groove (10) extends like a truncated cone and is enlarged towards the open end (13). The annular groove (10) is confined by ...

Each end of the rods surrounding the positioning sensor is provided with a coil, through which passes a current, whose intensity is automatically regulated as a function of the sensor readings in order to make the gradient of the magnetic field due to the rods and to the field itself zero within the sensor area.

The invention relates to a multi-disc brake comprising a stationary rotary disc (1) and a moveable rotary disc (2) which is mounted on a splined sleeve (5) sliding on a splined part (3a) of a hub (3) of axis (4) and with which the disc (1) is solid. An assembly of friction pads (6 to 9) can interact with the discs (1,2) under the action of a hydraulic jack (13). The splines (23,25) of the hub and ...
