Inventor: ELTZ HANS-ULRICH VON DER DR
IPC: D06B19/00
Filed: 1975-12-16
Abstract: Textile material in strand form is dyed under conditions of low bath ratios. The bath ratio is 1:0.5 to 1:2.5. The material is sprayed with the dye liquor and, without the formation of foam, is guided either through a system consisting of at least three cylinders or rollers, which has no centrifugal cylinders, or through a system consisting of at least three stationary bars. The material is thereby deflected, compressed and kneaded. The dyeing is completed thereafter. This process makes it possible, for the first time, to utilise the advantages of using a low bath ratio, coming within the abovementioned range, for the strand dyeing of textile material.

Patent DE-2618517-A1 (DE)
Inventor: ABERLE KURT ING GRAD
IPC: H01H50/20
Filed: 1976-04-28
Abstract: In the case of the relay, the winding (12) is surrounded by a magnetic yoke (13). The winding (12) grips a magnetic core (15), which is firmly connected to the magnetic yoke, and one end of a moving magnetic armature (16) which is constructed as a plunger-type armature. The other end of the magnetic armature projects out of the winding between limb ends of the magnetic yoke, or passes through an opening in one limb of the magnetic yoke. Formed between the magnetic armature (16) and the magnetic yoke is a gap (at 11) which interrupts the magnetic circuit. Connected to the moving magnetic armature (16) is a magnetic link (17) which, when the relay is in the energised state, virtually bridges over the gap (11), which results in the electromagnetic relay, which is constructed especially as a surge-current relay, being able to carry even a continuous current of the winding without major losses. In consequence, the advantage of the good attraction force of the plunger-type armature system can be maintained and the disadvantage of poor continuous-current strength can be avoided. <IMAGE>

Filed: 1976-05-07
Abstract: Continuous compounder for plastics or rubber powder, as in Parent Patent, has a stationary casing and a drivable homogeniser whose surface which cooperates with the casing, has an undulatory surface. The bottom and the homogeniser are formed by >=1 pair of superposed bars. The undulatory surface is located in the 2 opposite surfaces of the pair of bars and extends across or obliquely w.r.t. the longitudinal axis. The mobile one of the bars is driven by a crank drive to execute a rotary movement of its corrugation ridges in the associated corrugation valleys of the other bar. In this addition, the mobile bar is connected, in each end region, with a crank drive both of which have different crank dias (rk', rk"). That crank drive with smaller dia. (rk') is connected to the mobile bar at its discharge end whilst the other drive is connected to the mobile bar in its intake end region, via a guide enabling it to perform axial displacement. A relatively large intake vol. is available when the crank drives are in upper "dead point" position, the discharge vol. being smaller than the take-up vol. As a result moulding cpd. with low apparent density and high air content can be optimally processed.

Title: Rapidly rechargeable alkali metal-sulphur electrochemical cell - contg. additive converting sulphur chains to charged state
Inventor: WEDDIGEN GERT DR
IPC: H01M10/39
Filed: 1976-07-24
Abstract: Electrochemical storage cell or battery based on alkali metal and S with an ion-conducting solid electrolyte sepg. the anode and cathode compartments, contains an additive, in the cathode compartment, which converts the S chains to an electrically charged state to produce electro-migration of the S phase. The additive pref. partly charges the S chains positively and partly converts them into a negatively charged complex. The pref. additive is tetracyanoethylene. The batteries are designed to cover peak loads, e.g. in conjunction with nuclear reactors. Rapid and more complete recharging is possible, since the build-up of liquid S as insulator is prevented by making the phase in the cathode compartment more mobile.

Patent DE-2645771-A1 (DE)
Title: Continuous prodn. of plastics pipes esp. for drainage - from flat preformed sheet by folding up and forming longitudinal seam at place of use
Inventor: NIKISCH HORST DIPL ING
IPC: B29C65/20
Filed: 1976-10-09
Abstract: Continuous prodn. of straight and curved pipes and tubes, esp. of plastics, consists of making the tube by folding up a flat strip and forming a continuous longitudinal seam to cloe it as a finished tube. The sheet of starting material is pre-trimmed at works at least at its edges, and esp. is pre-curved at this stage to remove subsequent stresses; the sheet is then wound flat into a roll for transportation to the place of use; here it is unreeled from the roll, is folded up about its longitudinal axis into its final tubular form and the longitudinal stem is formed by welding, bonding with solvent adhesive or two-component adhesive, etc. Before rolling into its final form, any necessary trimming such as punching holes in the wall for drainage pipes, is carrid out on the sheet while still flat, either at the place of use of the pipe or at the factory. By applying axial compressive forces to the tube as it is being formed, the desired pipe curves can be produced. Used in partic. for plastics pipes such as those for drainage etc. The method enables fairly robust pipes to be produced, possessing a strength considerably in excess of simple self-weight supporting capacity, without the pipe needing to be produced in short lengths and then transported to site.
