Granted: 1989-01-12
Abstract: The leading drum, in the direction of used paper travel, has at least a generally solid cylindrical wall for mixing with water for softening and partial breaking up. The second drum also gives a partial breaking up action and sorts the fibre material. The sorting drum is divided into two sections, in the direction of material travel, each with a perforated cylindrical wall. The perforations in the wall of the first section are smaller than those in the second section. A suspension return system with a fibre reduction unit, lies between a trap for the suspension from the openings of the second section and a point between the two drums in front of the first sorting zone to return the matter.

Granted: 1989-06-15
Abstract: In the production of hollow bodies from oriented thermoplastic material, a cylindrical portion of a heated hollow preform is stretched, with a simultaneous reduction in the wall thickness thereof, at a starting temperature below the vitreous transition temperature of the material. A mandrel is positioned in the preform to support it during stretching, the outside diameter of the mandrel corresponding to the inside diameter of the preform. Directly before the mandrel is inserted into the preform the preform is subjected to re-alignment to adapt at least the cross-sectional shape of the mouth opening of the preform to the cross-section of the mandrel. The re-aligning operation is effected by inserting the preform into a sleeve adjoining a drawing ring for carrying out the stretching operation.

Abstract: A light pattern generator is utilized to produce an image which is projected onto a stage or screen. The image is derived from a beam of light. The light pattern generator comprises a heat resistant glass plate having a reflective layer deposited on one surface thereof. A nonreflective layer is deposited on the surface of the reflective layer. Both of the layers are etched to produce an opening extending through the layers wherein the opening has the shape of the desired image. The beam of light is directed through the transparent plate and the portions not passed through the operation are reflected by the mirror surface of the reflective layer. This prevents the buildup of heat within the light pattern generator. Any extraneous light which is received at the nonreflective layer is absorbed to prevent the escape of unwanted light and its projection to the stage.

Abstract: A clock generator for a pulse repeater of a receiver in a pulse transmission system comprises a forward filter (1) connected to its input (A), a difference former (2) whose positive input is connected to the output of the forward filter (1), a series arrangement connected between the output of the difference former (2) and the output (B) of the clock pulse generator and comprising a limiter (3), a time differentiator (4), a rectifier (5) and a narrow bandpass filter (10) in this order, and a feedback filter (6) connected between the output of the limiter (3) or the rectifier (5) and the negative input of the difference former (2). The limiter (3) is used to cancel intersymbol interference. The clock generator can be utilized in combination with a known pulse signal regenerator (1,7-9) of the decision feedback type to constitute a pulse repeater. Alternatively, a pulse repeater can be obtained by combining the clock generator with only a pulse regenerator (8, Fig. 2) whose clock input is connected to the output (B) of the clock generator, whose signal input is connected to the output of the rectifier(5) of the clock generator and whose output constitutes the output (c) of the pulse repeater. When using a known pulse signal regenerator of the decision feedback type, the forward filter can be common to the pulse signal regenerator and the clock generator and the respective feedback filters can have the same amplitude-frequency characteristic.
