A device for fastening a lamp on a surface, whereby a frame (1) of the lamp is provided with a round opening, a fastening plate (9) being turnably secured on said opening. In order to enable turning of angular lamps in particular into a desired position before the final fastening, the frame of known devices is provided with elongated holes for fastening screws. A disadvantage of such holes is that...

In order to reduce the noise level in pipe transporting installations, a pipe transporting apparatus is proposed for buffer tables, in which apparatus the pipe (30) and/or the group of pipes (20) is moved, in the case of the tables (10) with a horizontal supporting surface (18), by a drivable slide (32) across the table into its storage position, and in which apparatus a braking catch which can be...

Mixed polyester molding compositions comprising at least a pair of structurally different thermoplastic polyesters are stabilized against transesterification, whether during formulation or the downstream molding thereof, by having incorporated therein an effective amount of at least one mono-, di- or triester of orthophosphoric acid.

The pressure of the liquid or gas mixt. is increased so that porous particles are compressed and their density increases to become higher than that of the liquid or gas. Thus they can be sepd. by settling out or centrifugal force. Any other heavy particles also settle out. The rotors are pushed together by a spring. The mixt. approaches the rotors in the disection of the arrow and is thrown out to...

It comprises a tubular crucible (6) which contains the chosen material (7) and an electrical heating system to control its temp. This comprises several radiation sources (22) which are distributed longitudinally along the crucible. They locally heat the crucible and can be controlled to achieve the desired temp. distribution. The tube (23) is rotated to achieve isothermal conditions around the per...

The key comprises a key member (13) and a clamping bolt (6). The key member is of arched cross-section, so that when driven into a hole in the bolt its opposite edges (17-19) bear against opposite sides (20, 21) of the hole, generating a transverse spring force.

During the process drying phase, a fluidising bed (1) is maintained under vacuum, and excess pressure is applied during an emptying phase.

A first cover (5) is flexibly joined to a further cover (1). Parts of sheets (2) which are turned over are protected by the first cover also being turned over and located beneath them.

An impeller-type cutter drum for a chopper has a drum body including three drum disks arranged side-by-side and supporting two rows of blade holders which are spaced about the circumference of the drum body. Each blade holder supports a chopping blade and extends between a respective one of the outer disks and the center disk upwardly in an upwardly inclined and oblique manner. The front portion o...
