The invention relates to a device for the automatic assembly of the carcase of a vehicle pneumatic tyre, in which the tyre is wound and cambered to form the tyre blank in a single mounting operation, and to a process for producing a tyre on the device. The device is characterised by a winding drum with metal segments which is adjustable in diameter and by a respective bellows auxiliary drum which ...

A crushing apparatus is fitted with hammers which preserve the hammer spindle. The bores of these hammers have a wall which is made curved away from the hammer spindle towards the two edges, leaving a shorter, straight middle piece. Thus the individual hammer can execute a limited rolling movement on the hammer spindle, without unfavourably influencing the hammer spindle in doing so. Likewise the ...

In the course of a process for the direct reduction of iron ore or iron oxide pellets to give sponge iron in a reduction furnace (1), hot reduction gas is injected through a reduction-gas inlet (4), the gas flowing upwards through the descending charge, reducing the iron ore or the iron oxide pellets in the process and being drawn off as top gas through a top-gas outlet (5). In a cooling zone (9) ...

1. A rotor for beater mills equipped with rows of hammers (10) with parallel axes, a plurality of hammers swing-mounted on sleeves (9), the latter being retained in position between rotor disks (2) by means of bolts (8) passing through the sleeves (9) in an axial direction and secured in the outer rotor disks, thus characterized in that the sleeves (9) are mounted in bearing seats (4, 5) provided ...

The invention relates to a method for the separate winding of a plurality of multifilament spinning threads on a common shaft, in which, when an individual filament breaks, the operation of the common winding of the spinning threads is not interrupted, but, after the broken filament has been mixed into the remaining filaments of the spinning thread affected, this affected spinning thread is identi...

A refractory composition that is highly resistant to siliceous slag comprising from 45-85 weight percent chromic oxide and 15-55 weight percent alumina, said composition having a coarse grain fraction of -4 mesh and a fine grain fraction of -325 mesh comprising 40-100 weight percent chromic oxide.

The housing of web sectioning apparatus having a rotary knife assembly and a rotary cutting drum is provided with a pair of bearing surfaces. A frame is pivotally mounted on these bearing surfaces, and the rotary knife assembly is rotatably mounted to the frame eccentrically of the pivot axis between the frame and the housing. Thus, by pivoting the frame relative to the housing, the axis of rotati...

PURPOSE:To stay an unmanned carrier can on a specified stop point precisely for a specified period even if the function of a stop signal transmitter or the like is reduced or stopped at the stopped state of the car by arranging a control device on the car mounting side. CONSTITUTION:The car mounting side control device is constituted of a stop signal detecting circuit 13, an alternate magnetic fie...

A ski safety binding of the type in which a sole clamp is pivotally mounted about a transverse pivot axis on a base plate and is retained in a closed position for clamping a ski boot by means of a spring loaded latch device. During safety release the sole clamp is able to pivot upwardly about the transverse axis to overcome the latching force. To allow the sole clamp to be readily opened by hand a...

An automatic asparagus picking machine is disclosed comprising a chassis movable along a mound in which the asparagus are grown. The chassis has a picking tool which is mounted for horizontal and vertical translation at right angles to the direction of displacement of the chassis. The tops of the asparagus are back lit by a lighting system on one side of the mound and their images are picked up by...

Mixtures which are used for the production of polyurethane foam and which contain amines having primary or secondary aliphatic hydroxyl groups, and also customary quantities of trichlorotrifluoroethane and/or trichlorofluoromethane as a blowing agent, can be stabilized against the premature reaction of the components by adding 0.05 to 5% by weight of 2,4-diphenyl-4-methylpentene in which the ratio...

An amount of energy of an output laser beam emanating from a distal end of a flexible light guide is measured by arranging a partial reflecting mirror having a reflection factor of about 99% and a transmissivity of about 1% at the last rotating nod portion of the light guide nearest to the distal end. A heat sink is applied onto a rear surface of the partial reflecting mirror and a thermocouple is...

A new metal-containing high siliceous porous crystalline material related to the structure of zeolite beta, a method of making same and the use thereof in catalytic conversion of organic compounds. The anhydrous form of the new metal-containing crystal has a calculated composition, expressed in terms of moles of anhydrous oxides per 100 moles of silica, as follows: (W)Q2O . (X)M2/nO . (y)L2O3 . 1...

A heel holder includes a base plate mountable on the ski, a sole holder supported for vertical and transverse horizontal movement relative to the base plate, a first locking mechanism for yieldably resisting upward movement of the sole holder away from a closed position adjacent the base plate, and a second locking mechanism which prevents transverse horizontal movement of the sole holder until it...

In order to allow a compact design and low operating forces despite high retaining forces in a heel part for a safety ski binding, the sole hold-down is constructed as a part which can be pivoted separately in relation to the bearing block and whose pivoting is monitored by a spring-loaded, two-armed lever which can likewise be pivoted separately. By suitable selection of the transmission of this ...

The invention relates to a process for the preparation of material based on commercially available thermoplastic polyurethane elastomer which can be crosslinked by means of electron beams. Liquid crosslinking agent in a precisely determined amount is added to the polyurethane granules. The crosslinking agent diffuses into the polyurethane granules which are then again dry at the surface.
