Title: Extruder screw comprising entry and homogenising sections - has longitudinally divided flight land resulting in identical parallel dual threads, one open, the other blind-ended
Inventor: GRUENSCHLOSS EBERHARD DIPL ING
IPC: B29C48/65
Filed: 1976-03-24
Abstract: The extruder screw of the parent patent is divided into an entry zone and a plasticising or homogenising zone. At the upstream end of the plasticising zone, a flight land extending from the entry zone, divides longitudinally so that a new flight land is formed, in the plasticising zone, between the resulting 2 flight lands. This new flight land is open at the tip of the screw. However, a flight land, starting in the entry zone, ends "blind" at the screw tip. Plasticised material can pass from this flight land into the twin thread (formed by the division of the screw as described) over 1 of the dual flight lands, which has some radial tolerance between flight land edge and the inner wall of the extruder barrel. The material accumulates in the twin thread and conveyed toward the screw tip. The improvement comprises increasing take-up volume and throughout constructing indentically pitched all screw threads of flight lands in the plasticizing zone parallel to one another.

Title: Automatic control circuit for compressed air operated doors - uses resistance voltage divider network to control transistor which reverses operation of door valve
Inventor: STRANGFELD RALF DIPL ING
IPC: E05F15/02
Filed: 1977-01-26
Abstract: The automatic control system for compressed air operated droos has a logic circuit. Associated with the logic circuit is a central control circuit which controls the door valve. This door valve opens a door or doors when an opening order is actuated by a passenger and the door control is released by the driver. A similar procedure is used for door closing, except that there is an opening maintenance time period for certain doors. The logic circuit has a resistance network whose resistance ratio are determined. This resistance network is made up of several voltage dividers which are combined with diodes. Whilst these resistors can be grouped and act with the diodes by adjusted potentials, the potentials applied to the dividers determine the control of a transistor. This transistor causes inverse operation of the door valve.

Title: High temp. gas cooled reactor with top reflector cooling - by secondary gas flow of increased speed during fault condition
Inventor: WACLAWICZEK HERBERT V ING GRAD
IPC: G21C11/08
Filed: 1977-07-20
Abstract: A gas-cooled, high temp. reactor has a cooled top reflector, pref. composed of graphite blocks, with a downward flowing gas stream through the reactor core. Below the top reflector, and at some distance from it, there is a suspended roof contg. apertures, through which the stream flows downwards from a distribution chamber between the top reflector and the suspended roof. Pref., the upper face of the top reflector is cooled by a second gas stream. Specif., both the top reflector and the suspended roof are suspended from a common support frame cooled by the second gas stream. If a fault occurs and the reactor is shut down, e.g. due to failure of a blower, natural circulation builds up, causing reverse flow through the core and resulting in heating of the top reflector; heat is transferred from this to the second cooling circuit which thus supplies more heat to the steam generator and results in increased steam prodn. This operates the steam turbine at higher speed, resulting in the second blower being driven at higher speed, which provides sufficient cooling for the top reflector through the secondary cooling circuit.
