Patent DE-3542861-A1 (DE)
Inventor: SRIDHAR SRINIVASAN DR
IPC: C12P7/40
Filed: 1985-12-04
Abstract: Organic acids are prepared from their salts electrodialytically. At the same time, another acid is converted electrodialytically into the corresponding salt. Both electrodialytic conversions take place in the same electrodialysis unit. If the salt of the organic acid has been fermentatively prepared as, for example, malate from fumarate, it is possible both to prepare malic acid by electrodialysis and also to prepare fumarate from fumaric acid for the fermentation. Through coupling substrate and product streams in the electrodialysis, a closed circuit is formed.

Title: Method and devices for the downward conveying of highly consistent solid/liquid mixtures in pipelines
Inventor: JANSSEN KLAUS DIPL ING
IPC: B65G53/52
Filed: 1985-12-18
Abstract: Described is a method for the downward conveying of highly consistent solid/liquid mixtures which are conveyed in a continuously flowing manner in perpendicular and approximately perpendicular pipelines as well as devices for carrying out such downward conveying in the form of choke means which are contained in the pipeline. The method is especially suitable for the ultimate storage of radioactive waste or special waste in deep geological formations, e.g. in salt caverns. However, it is also of importance for other applications, e.g. for the placing of stowing material or plastics in mines via perpendicular shaft lines.

Patent DE-3624753-A1 (DE)
Title: Device on a crank drive inserted in a crank case
Inventor: SCHMIDT KARLWALTER DIPL ING
IPC: F16H21/36
Filed: 1986-07-22
Abstract: The invention relates to a device on a crank drive, inserted in the crank case, for converting the rotary motion of a crank shaft into a purely oscillating motion of a piston and of a connecting rod, connected to the latter, with a bearing part which is rotatably mounted on the crank pin of the crank shaft and is arranged in a manner which allows linear displacement with simultaneous transmission of tensile and compressive forces in the direction of the motion of the piston on a guiding part arranged on the underside of the connecting rod. The device furthermore has an arrangement for guiding the piston and the connecting rod in the direction of the longitudinal axis of a cylinder surrounding the piston. In order to minimise the outlay required for the construction of the device and the number of rotary joints required and in order to avoid causing any additional inertia forces, the connecting rod is, first of all, rigidly connected to the guiding part, the sliding track of the guiding part is, secondly, arranged perpendicular both to the longitudinal axis of the cylinder and to that of the crank pin, and the guiding part is, thirdly, articulated in a manner which allows displacement parallel to the longitudinal axis of the cylinder on at least one guide rail arranged in the crank case.

Title: Interior cable
Inventor: LUDL ANTON DIPL ING
IPC: G02B6/44
Filed: 1986-09-13
Abstract: In the case of cables which are laid indoors, the insulating materials which are used are intended to be largely flame resistant. The optimum insulating materials for the cores of electrical and optical cables are, however, not flame resistant or are only inadequately flame resistant.

Patent DE-3731616-A1 (DE)
Inventor: BECK HEINZ
IPC: A63C9/20
Filed: 1987-09-19
Abstract: A safety binding for cross-country and touring skis is disclosed. Two holders secured in a housing to the ski cooperate with two pegs that extend parallel to the point of the boot. By means of the hinge thus obtained, an exact ski guidance is achieved when the skier is normally moving forward. In case of lateral overload, the holding brackets are pressed apart after a predetermined resistance is overcome. The pins at the point of the boot are released. The boot can detach itself from the binding. By a special design and selection of materials, the elastic forces required for the binding to work properly are directly taken up by individual parts of the binding, thus minimizing the number of separate parts required.
