Patent DE-19609902-A1 (DE)
Title: Granular, porous, flexible injection tubing with water soluble coating used in jointing concrete structures
Inventor: MUELLER WERNER
IPC: E04B1/68
Filed: 1996-03-13
Abstract: Flexible injection tubing (1) introduces fluid materials into connecting- and expansion joints of concrete structures. Its shape is round, triangular, trapezoidal, rectangular, square or a derivative. It encloses a tubular channel (2) with desired cross section. A special new feature is the non-homogeneous nature of the tubing. It is made of granules, producing a porous structure (3) open to the passage of fluids. This is then coated or impregnated using a non-film forming, or a film forming (4), water soluble material, which reliably prevents inward permeation by fluid concrete or its components, into the pore structure and inner tubular channel.

Title: Heavy goods vehicle tank e.g. for environmentally dangerous fluid
Inventor: HESSABI IRADJ DIPL ING
IPC: B60K15/077
Filed: 1996-09-03
Abstract: The tank (1) comprises a chamber filled by an open-pored cellular flexible material (9), whose pores are occupied by the liquid load. The tank chamber has a number of lamella (10) panels, either arranged on hinges around the tank inner face, or tangential to a central shaft. The unhinged ends of the lamella are linked by a cable (20) to a winding winch axle (25). When discharging fluid from the tank, the winch cable is tautened causing the lamella to extend and expel the fluid from the open-pored material. When the winch cable is reversed, the pores relax and expand to admit a replacement fluid load. The materials for the open-pored cells, lamella and winch mechanism are selected in accordance with their suitability in conjunction with the fluid.

Title: Temperature probe having radially spring-loaded sensor unit for borehole measurements
Inventor: BRANDT GERHARD
IPC: G01K1/16
Filed: 1996-10-31
Abstract: This novel geothermal borehole probe comprises a carrier, with a temperature transducer (16) on its lower end (14). The novel feature is its orientation at the side of the probe, facing the wall of the borehole, during measurement. Also claimed is a method of determining migration within geological formations, into which a borehole is sunk and cased. A geothermal probe is lowered down the hole, during sinking. The temperature signal is recorded, registering temperatures against the side of the borehole casing. Also claimed is a method of density examination of subterranean hydraulic structures, especially of waste dumps. A vertical temperature profile is determined together with the temperature gradients, over a field of measurement, using the equipment described. The results indicate the direction of migration, and permits determination of the depths of subterranean flows.
Patent DE-19646213-A1 (DE)
Inventor: KARSTENS TIES DR
IPC: C08B1/08
Filed: 1996-11-08
Abstract: Disclosed is a method for producing cellulose derivatives wherein cellulose is impregnated with an alkali solution, the impregnated cellulose is selectably pressed out, and the cellulose undergoes a substitution or addition reaction, whereby the cellulose derivative is obtained with a degree of substitution DS. The applied cellulose is an ammonia activated cellulose. The molar ratio of the alkali to the AHG (anhydro glucose unit) in the cellulose at the beginning of the substitution or addition reaction does not exceed twice the valve of the desired DS. For the swelling of cellulose, no excess of alkali is required, which does not react to produce alkali cellulose but only adheres to the cellulose as a loose association product. Reagent consumption in the substitution or addition reaction is lower. Fewer secondary products are formed.

The redirection reels are assembled on the linear sled, and the ball thread spindle is rotated by a stepper motor (6), or similar, which causes the linear adjustment of the sled. The adjustment path of the sled, which corresponds to a certain angle of the crank shaft, is determined by a rotation pulse generator (7) or a linear path sensor (7a). The control of the motor is performed by electronic circuits in response to an engine temperature, a load, external temperature, etc.
