Title: Decorative chenille-imitation yarn - consisting of fibres having different dyeability and shrinkage
Inventor: HERX RAINER
IPC: D06B11/00
Filed: 1976-06-02
Abstract: The yarn has a caterpillar-like outlook and contains a major proportion (pref. about 70%) of polyester fibres, which can be dyed without any dyeing accelerator, or acrylic fibres, which can be easily dyed because of their loose molecular structure, and a minor proportion (pref. c.a. 30%) at highly shrinkable polyester or acrylic fibres. The threads are entwined together to form an endless sock, which is printed and drawn through a spiral duct whilst being fixed with hot air, and then wound on a spool. Multicolour printing is pref. Yarn produced by this method closely resembles the true chenilla yarn and yet is much cheaper. This yarn can be used for decoration of garments, curtains, furniture, etc. It has velvety outlook.

Title: Dyeing and sealing biological probe - by coating cover plate with dye, the slide carrier with resin and adhering
Inventor: GEATING JOHN AUTEN
IPC: G01N1/31
Filed: 1976-08-06
Abstract: A biological probe esp. blood probe with an air dried, microscopic slide carrier is dyed and sealed by 1) preparing a viscous soln. of a transparent resin in a solvent mixt. of an organic cpd. with water; 2) coating a cover plate on one side with a biological dye; 3) coating the slide carrier with the viscous resin soln. using an amt. that is smaller than the surface of the cover plate; 4) putting the dyed surface of the cover plate onto the viscous soln. and 5) leaving the cover plate on the soln. that the surface tension of the liquid pulls the cover plate onto the slide cover. In this last step the soln. spreads and covers the prble and slide carrier and the soln. absorbs the dye and brings it into contact with the probe, drying it. Dyeing and sealing can be carried out in one step.

Patent DE-2708642-A1 (DE)
Title: Valve assembly for nuclear power plant steam line - has valve casings stronger than discharge pipes to prevent casing damage
Inventor: SCHABERT HANS-PETER DIPL ING
IPC: F22B37/44
Filed: 1977-02-28
Abstract: Steam power plant, esp. a nuclear power plant, has a steam line passing through a wall; a valve in the steam line is further connected to several other valves branching out from it. The housings of these valves are all connected along side one another (in parallel) to the housing of the main valve; each of these subsidiary valves has a smaller bore than the main valve; in addn., the resistance bending moment of the connecting points at which these subsidiary valves are connected to the main valve casing is at least twice as large as the resistance bending moment of the ducts or pipes leaving these valves. Pref. the ratio of the moment is 4-10. By making each valve considerably more robust in its support and connection to the main valve than the pipe departing from it, the result is achieved that a crack or fracture in the pipe will not result in a leakage in the valve upstream of it. By comparison with a previous arrangement, where all the subsidiary valves were arranged in series, the moments exerted by the thrust are considerably reduced.

Title: Telephone exchange call-back connection circuit - has counting chains in branch exchange translations connecting call-back requests as required
Inventor: EIFLER FRIEDRICH ING GRAD
IPC: H04Q3/62
Filed: 1977-08-04
Abstract: The circuit is for step-by-step selector systems in main and branch exchanges, with subscriber circuits connectable by selector stages to branch exchange translations. The subscriber circuits can be connected through tie-lines to main exchange translations, whose dialling translations, which can be connected by further selector stages to the main exchanges translations, make a connection to a main subscriber line in case of through traffic, and to another extension in case of a call-back. Call-back circuits (RF1-RFN) are allocated to the branch exchange translations (UUE). When free, they can be connected by a common control unit (RFG) to the branch exchange translations (UUE). These call-back circuits have in addition to a pulse responder a counting chain which controls the dialling pulses from the branch exchange translations (UUE), so that in case of a call-back to extensions (TA1-TA2) in a branch exchange (UA), a call-back extensions circuit (RTS) directly allocated to the branch exchange translation is connected. In case of call-backs to subscribers (TA) in the main exchange (HA) the extension line (NAL) is connected.
