Title: Winding control - has induction motor to alter reciprocating guide slip at each winding station
Inventor: FROEHLICH KARL-WERNER
IPC: B65H54/38
Filed: 1979-04-12
Abstract: The slip is altered by varying the voltage applied to the coils of the induction motor, and the coils are alternately connected to two current supplies with identical frequencies. The winding unit has a preset frequency generator, and the reciprocating guide is connected to the frequency generator by one of the two current supplies. The supply circuits have different voltages through transformers located behind the frequency generator and there is a change-over switch to connect one or other of the two circuits. This change-over switch changes the induction motor from "star" to triangle" and back. The introduction of an induction motor allows a central unit to control the constant speed of the assembly, with individual control at each winding station to ensure that the spools are wound correctly, without wobble or other irregularities.

Title: Rope speed limited abseiling mechanism - has single overhung pulley outside housing and driving gear for centrifugal brake
Inventor: KUTSCHERA WOLFGANG
IPC: A62B1/10
Filed: 1979-05-12
Abstract: The mechanism lowers persons or loads by the rope travelling through it, the rope being reeved round a fixed part of the periphery of a pulley so that it cannot slip. When a rope end is pulled, a centrifugal brake limits the rope travel speed, this brake being driven via a speed-increasing gear with an input shaft in bearings in one of the housing walls. The pulley and the driving gear wheel are mounted on this shaft. Only one pulley (38) is provided, on the outside of the housing and overhung. The driving gear (20) is on the opposite side of the housing wall (33) to the pulley.
Patent DE-2922814-A1 (DE)
Title: Chipboard fibre mat - mfd. on moving carrier by sprinkler drums and vibratory screens
IPC: B27N3/14
Filed: 1979-06-05
Abstract: The Parent Patent 2422468 described a sprinkler device for the prodn. of a mat of assorted chips which can be pressed into chipboard panels. A chute in the shape of an inverted V distributes the material over two inclined vibratory screens. The overflow of the screens drops on two revolving sprinkler drums which throw the coarser chips over the layer of finer particles of the screen underflow. Contrary to the Parent Patent where a part of the feed by-passes the screens and is dropped directly on the carrier, it is suggested to feed the screens through two contrarotating sprinkler drums, without any gap between them. The improved device applies more completely screened material on a moving carrier without having to raise the speed of motion of the appts.

Title: Textile machine top drafting roller - has cylindrical body with resilient sleeve of varying thickness enclosing air cushion buffer
Inventor: SLYKOV GENNADIJ NIKOLAEVIC
IPC: D01H5/80
Filed: 1979-09-18
Abstract: Top roller for drafting systems in textile machinery comprises a cylindrical body with an outer sleeve of resilient material whose length is somewhat greater than that of the body. The sleeve is affixed to the body by flanges at both ends which leave a small gap between the cylinder and the inner surface of the sleeve, the flanges being inclined at an acute angle to the extended line of the cylindrical surface. The thickness of the sleeve diminishes from the central section towards both ends, with the ratio of the flange thickness to the central sleeve section being within the range 1:2 to 1:5. This construction gives a uniform stiffness along the length of the sleeve, and uniform pressure on the material being drafted, making it suitable for use in high-speed drafting systems.
