Title: Method and apparatus for coating pipes
IPC: B28B/
Filed: 1987-10-14
Granted: 1992-09-02
Abstract: A method of coating pipes with concrete comprises conveying a series of pipe sections to a concrete coating station, rotating a pipe section about its longitudinal axis at the station and applying concrete to the outside of the pipe (1) during rotation whilst continuously feeding a line (3) to the rotating pipe to form a winding of line around the leading end of the pipe, subsequently feeding a wire (5) together with the line to the rotating pipe to form a winding of wire overlaid with line around the pipe during the application of concrete, and cutting the wire at a predetermined time prior to completion of the concrete coating whilst the pipe is still rotating whereby the wire is wound within the concrete coating, and continuing to feed the guide line to the rotating pipe after cutting of the wire to wind the line around the tail end of the pipe. Apparatus comprises a plurality of rollers (6, 7, 9, 10, 11, 12) including cutting elements (8) on rollers (7) and drive means to feed wire and a further series of rollers (4) for feeding line in a controlled manner.

Abstract: The machines concerned are for the injection-moulding of plastic parts, having a platen for the mould, which platen is guided movably on tie bars between fixed end plates, as well as a mould closing mechanism, in particular a hydraulically operated toggle-lever mechanism, and having ejector elements for the workpieces when the mould is open, which elements pass through the platen in the direction of movement and are longitudinally moveable in relation to the platen. In order to improve a closing unit for such machines, simplifying the ejector mechanism and its drive and considerably increasing the opening stroke, it is proposed that the mould closing mechanism (6) rests on a locking plate (14) which is arranged between the platen (5) and the end plate (2), parallel thereto, is guided on the tie bars and on which the ejector elements (9) are fastened. It is also proposed that the distance between the platen (5) and the locking plate (14) can be set, at least in two end positions. <IMAGE>

Title: Air-regulating unit, process for regulating air flow and use of a buoyant body in such a system
IPC: B65G53/66
Filed: 1988-06-24
Granted: 1993-05-19
Abstract: The new invention concerns the regulation of air volume in a conveying system comprising an air collecting line (37) in which the air volume and the corresponding air velocity, respectively, is regulated in the individual conveying pipelines (30-36) by a lifting body (4) resembling an airfoil. The latter works like a throttle flap and moves from an incidence angle ( alpha ,  beta ) of at least 10 degrees in the completely open position to 90 degrees in the closed position as a result of the lifting moments acting on it. The lifting body (4) itself regulates the air volume by means of blocking the air line cross section to a greater or lesser extent, wherein a balance is adjusted in every case between the air forces and lifting moments, respectively, which act at the lifting body (4) so as to be directed in a closing position and a counterweight (5) or countertorque, respectively, acting at the lifting body (4) in the opening direction. A responsiveness which has not been previously achieved can accordingly be achieved from every position and an optimal regulating characteristic, e.g. at an approximately constant air velocity, can accordingly be achieved independently of the air resistance occurring prior to the regulating unit.
