A toe piece for holding a ski-boot in a safety ski binding, which toe piece is pivotable against a biasing force when excessive side forces occur. The toe piece includes a base plate and a pair of elongated, generally parallel side members, each of which is pivotally mounted at one end of the base plate. A coupling member pivotally connects the other ends of the side members to each other to form ...

A thermoplastic film structure comprising a base portion of a thermoplastic resin which comprises polypropylene and a coating portion of an alkali metal salt of an alkyl sulfate is disclosed. The film is characterised by improved anti-blocking characteristics without the attendant problems associated with decreased clarity, adhesion and wettability common to films treated to improve their anti-blo...

Process for the production of expandable granules based on polyaryl ether sulphones and/or polyetherimides, containing 5 to 20% by weight of a physical blowing agent, the blowing agent and the polymers being mixed in an extruder and then being extruded directly into a medium at a temperature of less than 40 DEG C, and a process for the production of foams from expandable granules based on polyaryl...

PURPOSE: To keep complete seal of a piston and an inner bore forming a hydraulic actuator by fixing one end of a protective boot to the outer edge of the piston, extending it from the piston through a bore, and fixing the other end of the boot to a caliper. CONSTITUTION: A protective boot 23 is provided with two flexible boot portions 25, 27 and a bearing ring 29 made of less-frictional material. ...

A method of forming slots in the coupling disc (e.g., the armature or rotor) of an electromagnetic coupling such as a clutch or brake. The method is carried out by effecting relative movement between the coupling disc and a laser beam in such a manner as to cause the beam to trace the perimeter of the slot to be formed and to cut a slug of material from the disc. Also disclosed are coupling discs ...

An improved heavy-weight, nonapertured, nonwoven fabric of hydraulically entangled synthetic organic staple fibers has a unit weight of 200 to 850 g/m<2> [6 to 25 oz/yd<2>], a strip tensile strength of at least 0.26 (N/cm)/(g/m<2>) [5 (lb/in)/(oz/yd<2>)] and a resistance to disentanglement of at least 50 alternate extension cycles. The fabric is much stronger than such prior art heavy-weight nonwo...

The physical and mechanical properties of closed cell phenolic foam are improved by incorporating into certain foamable phenolic resole compositions small quantities of alkyl glucosides, particularly methyl glucosides. The alkyl glucosides also improve the process for preparing the closed cell phenolic foam.

In the production of a nonwoven fabric, for example for use as or in a papermakers fabric, an array of sheath core yarns of which the core has a higher melting point than the sheath, is fed in spaced parallel disposition to peripheral grooves (34) of a pinned roller (24) arranged in nip forming relationship with a press roll (28). The material of the sheath is melted as the yarns move into and thr...
