The invention relates to a method of welding together plastic pipes which are unwound from a roll, and an apparatus for regeneration of the shape of plastic pipes before the welding operation. The invention consists in that first of all the shape of the plastic pipe is regenerated by closely enclosing the plastic pipe over part of its length in a cylindrical mould, then heating up the mould until ...

A method for the production of frames from rigid plastic profiles for use on refrigerator cabinets and in particular on chest freezers, which comprises forming the plastic profiles, mitering and welding the edges of the plastic profiles to form a frame having sharp-edged corners, and rounding at least one of the sharp-edged corners by means of thermo-forming. The invention also comprises the finis...

A system for feeding production and/or packing material onto manufacturing lines, which system has compartment for storing the material; guide tapes for mobile trucks traveling between a storage area and manufacturing lines. The guide tapes define routes selectively traveled along, in use, by the mobile trucks for transporting and feeding the material to the manufacturing lines. A computer control...

The charge-acceptance capacity of the negative electrodes of a starter battery, which is greatly reduced at low temperatures under the freezing point of water by an expander additive, can, at the price of only a small deterioration in the cold-startability, be improved by reducing the expander concentration in a part of the electrodes of each of the negative plate groups and/or by these plates con...

Machine unit for comminuting and conveying vegetable material, meat and the like, having a feed apparatus, a screw pump and a comminution apparatus, the feed apparatus having a feed funnel and, below the feed funnel, a worm shaft having a drawing-in screw helix and the screw pump with its screw rotor being connected to the worm shaft via a connection part. The comminution apparatus is arranged bet...

The flotation method for separating off solids from a suspension takes place utilizing centrifugal forces. In the clarifying compartment (1), the suspension is set in rotation so that flotated portions are particularly effectively conducted towards the centre of the clarifying compartment (1) and concentrated. Viewed axially, flotated portions and the remainder of the suspension are conducted in t...

The X-ray appts., for mammography, has a moving slit diaphragm (4) to blend a fan-shaped beam bundle (2), which is moved over a picture field. A beam detector (6, 7) has a scintillator (6) and an electronic image converter (7) in optical contact, such as a CCD converter. A scattered beam screen (8) is in front of the beam detector (6, 7), in the direction of light travel, adjusted synchronously wi...
