An apparatus and a process for the production of frothed polyurethane foams: the reactive polyurethane components are mixed with a liquid low-boiling blowing agent and a nucleation gas by a mechanical mixer under pressure controlled conditions in a mixing chamber to keep the blowing agent in the liquid state and cause a fine dispersion of the nucleation gas. The reactive polyurethane components, t...

A standing sunshade has a cover (6) with ribs (10) upon which is stretched a covering material (16) composed of separate sections (161, 162) and having beads (24) on the side facing the ribs (10). The beads are inserted into longitudinal grooves (18, 20) in the ribs (10) and have a narrow opening slit (22). Mounting the sunshade material and replacing individual sections thereof are thus made easi...

The present invention relates to a ski safety binding intended to hold, in a releasable manner, the front of a boot (2) mounted on the ski (3), including a mechanism for compensating a forward fall comprising a pedal (12) forming a forward-fall sensor (feeler). This binding is characterised in that the front end (12a) of the pedal (12) is located, in the rest position of the pedal, at a distance (...

A combination of a ski boot (12) and a releasable ski binding (14) which attaches the boot to a ski (15). The binding includes first connecting portion secured to the ski, second connecting portion secured to the boot, and a plunger combination for releasably coupling the first and second connecting portion so that the boot may release from the ski in the forward, backward or lateral directions. T...

A method of making an apexed bead for a tire comprises the steps of providing a supply of rubber and a supply of bead wire. The rubber is extruded around at least one bead wire. An apex leaf projects from the rubber extruded around the bead wire to form a bead ribbon. The apex leaf extends in a direction laterally from the extent of the bead wire and is located between a pair of planes which are c...

A transport vehicle (10) with a chassis (14) having an interchanging device, an interchangeable body (19) which can be positioned on the chassis (14) and removed and has at least one unit (22) which is to be driven, a coupling line (26) in particular for connecting a driving drive device (28), which is present on the vehicle side, to a power output device (24) which is to be driven and is present ...

The invention relates to a press for making dimensionally stable stacked pressed articles from a powdered material. The said press has a lower (16) and an upper pressing ram hammer with a basic body (1) which is fixedly supported in the press and in which there are arranged hydraulic annular piston systems (2, 3, 4) which are arranged one above the other. According to the invention, the basic body...

The device is comprised of a sole bearing plate (1) susceptible of moving transversally with respect to the ski (4), along a preset trajectory, for example by pivoting about an axis (Y). The front stop (3) is connected to the bearing plate (1) through a linking member (6) which is elastically deformable. The device applies to ski equipment.

This arrangement enables high-resolution screens (HB) with a single pixel selection to be used and avoids the derivation of a check code from the serial picture data stream which is problematic at very high frame buffer read-out frequencies. To form the check code, the picture data, which are entered into the frame refresh buffer (BW1), are entered in parallel to another similar buffer (BW2) which...

The present invention relates to a novel ethylene/pentene-1 copolymer whose molded film has a good balance between impact resistance and tear properties and high transparency, also is prominently reduced in a variation of the transparency even after subjected to a heat treatment, and further shows high blocking resistance, provided that the copolymer fulfills specific requisites. The invention als...

A lightsafe masking film is disclosed which includes a transparent substrate, and a transparent, lightsafe layer peelably provided over the surface of the substrate and containing a light yellow colorant and a blue colorant so that the color of the lightsafe layer is light green and the spectral transmittance of the lightsafe layer does not exceeds 1 % in the wavelength region of between 350 nm an...

Polypropylene foil-bonding agent-metal composites are disclosed, in which polypropylene modified by carboxyl groups and/or anhydride groups is used as bonding agent.
