A centrifuge is disclosed designed either as a solid bowl centrifuge or separator for separating solids/liquids mixtures. A centrifuge drum having an outer jacket is provided with apertures positioned in the jacket. Through the apertures at least a partial discharge of concentrated solids phase occurs thereto. A control device preferably in the form of a disk provides a surface spaced at a small i...

An apparatus for producing a plastic container having occludable closure strips comprises a source for the closure strips, a rotatable casting cylinder having a pair of spaced apart circumferential grooves defined therein, a mechanism for advancing the closure strips to the casting cylinder, an extruder for casting a plastic film onto the casting cylinder so that it becomes connected to base porti...

According to the invention there is provided a floor treating machine having laterally spaced drive wheels driven by separate electric traction motors under electronic control so as to be driven by separate train of pulses, comprising means for recording the trains of pulses to the traction motors and means for replaying the record to reproduce the trains of pulses whereby the machine will repeat ...

High-purity metal powder is made by the electron beam melting of a starting material in rod form in a vacuum wherein the molten metal is momentarily caught on a spinning plate rotating at high speed and flung therefrom and thereafter solidified by cooling. The metal on the spinning plate is bombarded with an electron beam that is so focused and periodically deflected that its focal spot is many ti...

A heel holder includes a sole holder which is supported for pivotal movement about a horizontal axis on a support member and has a control surface. A locking lever pivotally supported on the support member has a nose engageable with the sole holder control surface. A spring housing having a release spring therein is pivotal about the sole holder pivot axis, and a slide member movably supported in ...

The invention relates to a ski binding which has a sole plate which bears two or more jaws retaining a ski boot belonging thereto, and which is pivotable both about a vertical axis extending substantially perpendicular to the top of the ski and about a transverse axis and is retained in the skiing position by a resilient retaining device which, as a function of the pivoting movement between the so...

A capillary-piece sheet, which can be used for example as an intermediate layer of insulating glass, consists of strung-together capillary pieces made of a thermoplastic, which are joined together at their front sides by at least one thermal cut. In order to manufacture capillary-piece sheets of relatively large surface-area requiring no cover films, the capillary pieces consist, for open-pored co...

The invention relates to a safety ski binding for touring and downhill skiing, having a plate (14) mounted on the ski (50) so as to be rotatable about a vertical axis (46). The plate (14) has attachment elements at the front and the rear for the boot (10). The front end of the plate (14) is attached swivellably to a rotary plate (42) by means of an axle (38) which is attached to said plate and run...

A shape-forming apparatus (10) for carcases of radial tyres is described. In the shape-forming apparatus (10) the expansion of the forming apparatus is exactly controlled by a central, expandable bellows (16) in which a narrow section of the, in the axial direction, central region of the forming apparatus starts the expansion. Preferably an arrangement of wires (17) extending in the axial directio...

In order to improve the accuracy of borehole survey systems utilizing probes with inertial components including inclinometers, two ring laser gyro units are included to provide rotation information 56, 58 to the system. When the probe is moving in a borehole, inclinometer information 50, 52, 54 is used 78 to produce a synthetic rotation signal 80 to take the place of a third gyro and the earth's r...

A spring-applied, air-released parking brake, having a manual release mechanism with an automatic reset feature. To release a spring-applied parking brake, in the absence of air, a torsion bolt having a cam member formed on it is manually rotated to a position aligning the cam with an elongated slot in the piston push rod of the parking brake cylinder. This allows the piston to be extended in a di...

A bonded plastic structure which comprises plastic parts of reaction injection molded polyurethane or reaction injection molded nylon coated with a primer coat and bonded together with a thermoplastic block copolymer. The primer coat comprises a moisture-curable polyisocyanate. The block copolymer comprises from 40 to 80 weight percent crystalline polyester or polyamide segments and 20 to 60 weigh...

The invention relates to a method for producing nitrocellulose-based carbon black in the form of chips. The recipe constituents are blended into a mixture and converted at an elevated temperature into a dispersion in a suitable device which achieves the desired degree of kneading such as a kneading machine or roller die extruder.
