For grinding a tyre 2 mounted on a vehicle, an abrasive band 5 stretched around rollers 51, 52, 53, 54 and 46 mounted on a frame 4 is used. A jack 7 takes all weight off the tyre 2. A counterweight 45 pulls the frame 4 towards the tyre 2. The pressure of the abrasive band 5 against the tyre 2 can be adjusted to a very low value.

In known solid bowl decanter centrifuges, the suspension is fed to the decanter centrifuges axially under excess pressure and the phases which are separated from one another in the centrifuge are discharged from the centrifuge axially. In order to bring this about, special sliding ring seals are required which are complicated, costly and also liable to faults. The risk of blockage of the radial ch...

By means of the device, portions of a paper or film web 14 are inserted between the food slices. The cutting apparatus with the knife 11 is controlled by a step motor which is started by the cutting machine cutting the slices. The triggering pulse of a further step motor, which drives the paper feed 4, is derived from the position of the cutting apparatus. A uniformly driven conveyor belt 6 extend...

The invention relates to a sheet deliverer for a sheet-processing machine, in particular a printing machine for offset printing, in which a conveyor (1) releases the sheets (3) in a horizontal alignment above an auxiliary sheet pile on a movable base. In this sheet deliverer, a plurality of bases can be inserted as intermediate pile bearers (6) in the gap between two sheets following on from one a...

The cutting of brittle bodies, in particular hollow bodies or plates, for example of glass or ceramic, is widely used in technology. In hitherto known laser-cutting methods, in each case a mechanically complicated movement of the laser beam relative to the body is necessary. In the method described here, the body to be cut is heated at the surface along the cutting line by the action of the laser ...

In wet-wash separation of solids according to the their density in a separating device by sink-float separation in a centrifugal zone of a rotating container with a transport device for the discharge of the separated solids, difficulties can arise during the discharge of the floating material which can be caused by unfavourable friction ratios of the floating material relative to the transport dev...

The known earth carriers for electrodes of lead-acid batteries usually comprise grids which are made, for example, by metal casting, from expanded metal, as a lead/plastic composite grid or as an expanded composite material grid. Their disadvantage lies in a relatively large weight and/or manufacturing outlay. Using the novel earth carrier, the lead mass is intended to be reduced to the electrical...

The invention relates to an auxiliary device for the rewinding of threads, which can control the thread take-up tension of a thread (Y) having a linear density corresponding to that of a thick thread. The auxiliary device is designed in that a covering portion (31a), which covers essentially the entire conical portion (4a) of a thread-delivery bobbin (4), is provided on a balloon-inhibiting device...

Ski binding comprising means (14) for holding the heel and means (15) for holding the front end of the boot, in which binding a shock-absorbing element (22, 23) is inserted between at least two existing pieces of the binding which are not intimately linked, so as to permit multidirectional low-amplitude movements between these two pieces with the aim of filtering the vibrations and absorbing the s...

A system and method for optically measuring parameters including dry basis weight, basis weight and moisture content of fibrous sheet materials during manufacture without scanning. The system includes means for reflecting modulated light as parallel rays perpendicularly incident upon one surface of a traveling web, and means to detect light transmitted through the web at least at distinct bands of...

Test carrier/analysis system for analysing a constituent of a liquid sample, in particular a body fluid. The system includes test carriers having at least one test section which contains reagents. The reaction of the reagents with the sample leads to an optically measurable change in a detection layer of the test carrier. Furthermore, the system comprises an evaluation device (1) having a test car...

The invention proposes a bracket-like tool which makes it particularly easy to remove relatively small-volume lamps from the lamp holders or to insert them therein without the fingers having to touch the glass bulb.

The invention relates to an optical measuring arrangement for fast, contactless and non-destructive determination of both characteristic electrical semiconductor parameters such as charge-carrier concentration, charge-carrier mobility and electrical conductivity, and the stoichiometry of specific ternary and quaternary compound semiconductors. The determination of the semiconductor parameters is c...

A laterally releasable front jaw of a ski binding has a sole hold-down (11) which yields upwards due to spring means (13) and rests under spring prestress against the upper side of the sole. The underside of the front part of the boot sole (16) is supported on a resting plate (12) which is constructed to yield resiliently due to further spring means (14) in the opposite direction to that of the so...

The invention relates to a heel restraint having a base plate on which a bearing block capable of pivoting out laterally is arranged, in which a pivot head is mounted on a transverse spindle. A restoring spring is provided between the base plate and the bearing block. In addition, a locking device which holds the bearing block in its central position is also provided. In this heel restraint, in or...

A safety ski binding, preferably for engaging the front of a ski boot.
