Title: Cable core identifying device - has sender and receiver with electro-optical transducers for each core
Inventor: LAASS HEINZ
IPC: G01R31/02
Filed: 1974-02-11
Abstract: The sender consists of two groups of resistors so connected through diodes to a supply wire, that the current can flow through one group only in the positive direction, but through the other in the negative directions. Diodes are allocated to each individual resistor, or to a subgroup of resistors. The resistor groups have resistors connected in series, with junction points connected to terminals; or they have a common point, with other terminals individually accessible; or perhaps a combination of the two connection methods. Indication of the identified cable core is carried out in the receiver by electro-optical transducers, allocated to each cable core directly or through a switch. A missing connection or excessive resistance is displayed in a test circuit.

Title: Switching circuit for selection of data routes - is used communication systems with flip-flops to sequentially link data routes
Inventor: WAGNER HORST
IPC: H04Q3/62
Filed: 1974-09-07
Abstract: A switching circuit control provides maximum utilisation of incoming lines to a telephone communication substation. Input selector keys (T10, T20, T30) are coupled to gating circuits (V10, V20, V30) that condition switching circuits (Z10, Z20, Z30) controlling transmissions to the substation (V2). In operation, actuation of the priority bay (T10) results in signals (L11) (L12), being transmitted to AND, OR and NAND devices to set a flip-flop (FF10) to activate the switching selector circuit (Z10). If the bay (T10) is again actuated a transfer signal (S20) is then generated to set the second flip-flop (Z20) and open a second communication path. This procedure is repeated with respect to the third stage and provides automatic routing of data.

Title: Screw plasticising of polymers with degassing domes above screw - acting as falling film evaporators with continuous surface cleaning
Inventor: ELLEGAST KONRAD DR
IPC: B29C48/76
Filed: 1974-10-19
Abstract: A method of degassing polymer smelts and polymer solns. in screw plasticisers consists of constructing the degassing domes of the machine as falling film evaporators. In one embodiment, the falling film evaporators are continuously washed by a stream of the prod.; more specif., almost the entire prod. flow is recycled as a falling film flushing stream. In another embodiment, intermittent flushing of the falling film evaporator is carried out. There is no opportunity for the matl. condensing at the walls of the dome to polymerise and form a scale which would either have to be removed or would cause trouble if it fell back into the plasticiser. With this arrangement, fresh matl. is continuously brought back into the plasticiser so that premature polymerisation cannot take place.

Title: Phosphate contg. infusion solutions - contg. organic phosphates occuring in human carbohydrate metabolism, e.g. glucose or fructose phosphate
Inventor: PICHLER KARL
IPC: A61K38/01
Filed: 1975-04-28
Abstract: Phosphate-contg. infusion solutions (esp. fully balanced infusion solutions) contain as the phosphate component phosphates which occur in the human organism and either are intermediate products of carbohydrate metabolism or are closely related to such intermediate products. Phosphates are pref. glucose phosphate, fructose phosphate and glycerol phosphate. The infusion solutions pref. additionally contain calcium and/or magnesium ions and pref. have a pH of 5.5-8. The use of organic phosphtes occurring in human carbohydrate metabolism permits infusion solutions to be formulated which are of physiological pH and in which usual incompatibilities with phosphate (e.g. precipitation of Ca ions) are avoided. The phosphates used are non-toxic and are readily broken down by the organism so that optimal incorporation into the metabolism is ensured.
