Method and apparatus for use in building a closed torus tire. An expandable sleeve having an inflatable portion expands to wrap a sheet of tire building material partially about a disintegratable generally toroidal core. A bladder beneath the sleeve is then inflated to roll the sleeve toward the core causing the edges of the sheet to flip or snap from the sleeve surface to the core surface. The ap...

A surgical instrument (1) (Fig. 1) is used for transurethral operations in the prostate region. The instrument essentially comprises a guide tube (3) having a handle (4) on the outer end, an eyepiece (5) and connections for the rinsing liquid as well as for a light source. At the inner end of the guide tube (3) there is located, projecting somewhat beyond the latter, an excision element (9) which ...

A flexible polyurethane foam for sound insulation purposes has viscoelastic properties in the temperature range of - 20 to + 80 DEG C and a loss factor of at least 0.3, in the case of a density of less than 90 kg/m<3> and a modulus of elasticity of less than 10<6>N/m<2>. The foam is obtained by reacting a polyisocyanate with a polyol, in which at least one component has an OH-number of 180 to 400....

This invention pertains to a polyester composition containing finely divided polymer particles in a substantially homodisperse distribution. The polymer particles are prepared in an emulsion-polymerization process and are crosslinked. The polymer particles exhibit an extremely narrow grain-size distribution and are incorporated into the polyester during the synthesis thereof. The invention also re...

The invention relates to a safety ski binding, having a guide plate which is displaceable on a guide rail and is supported on thrust springs which are supported fixedly on the ski at the other end. The guide plate bears a pivot pin as a vertical axis, about which a pivot plate, carrying a bearing block, can be swung out horizontally, this optionally occurring only after predetermined vertical rele...

The heel holder (4) and a front jaw (49) of a safety ski binding are jointly arranged on a sole plate (2) or the like which is pivotable exclusively about a pin (3) arranged in the central region. The heel holder (4) and the plate (2) are retained in the downhill position by the same locking part (18, 24, 45, 51, 64), which can be moved against the force of a single spring (12) as a function of th...

Prodn. of closed-cell olefin polymer articles comprises heat-plastifying a normally solid olefin polymer (I), then admixing it under an elevated pressure with a stability control agent (II) and a mixed blowing agent(III).
