Patent DE-4104185-A1 (DE)
Inventor: MUELLER HANS
IPC: B29K105/08
Filed: 1991-02-12
Abstract: In the method for partially restoring a sewer (12) buried in the ground, a fibre mat (19) which covers the damaged zone of the sewer (12) on the inside and is impregnated with curable resin is placed around a hose-shaped support (6) of a packer, which support can be deformed by means of pressure. The external diameter of the support (6) is considerably smaller than the diameter of the sewer to be restored. The length of the support is larger than the wound fibre mat. The resin-impregnated fibre mat layer which is located facing the hose-shaped support (6) is fixed on the hose-shaped support by increased frictional engagement. During the increase in the diameter of the fibre mat winding, which is carried out by inflating the hose-shaped support, the hose-shaped support is rotated with the fibre mat winding, and the fibre mat layers are pressed against one another during the enlargement of the diameter of the winding. The resin which is displaced in consequence is then pressed into cracks (10) and into other damaged points in the tubular section of the sewer which is to be restored. A fibre-free resin ring is formed on the ends of the cladding. <IMAGE>

Title: Recognition and correction circuitry for faults in RS coded data blocks - has data word forward counter transmitting target value in determining zero position
Inventor: MESTER ROLAND DIPL ING
IPC: H03M13/15
Filed: 1991-02-25
Abstract: The fault recognition and correction circuit has a syndrom generator in the data stream of the RS coded data blocks, a detector of blanking-out in the generated syndroms, and a device for application of a specified Euclid algorithm. A fault detector operates on a zero position search according to Chien. The data words in a data block are counter by a forward counter (22 - 24), which transmits a target value (X) during detecting a zero position according to Chien. A first memory receives the counter values, which can be read-out at the end of each data block for writing into a second memory under a control signal action. A third memory (26) receives the fault values simultaneously with the storage of the counter values. USE/ADVANTAGE - RS code compiler, with real time correction of data of continuous data stream at very high data rate.

Title: Fibre tensile strength test for silicon oxide fibre - measures extent of bend on the fibre up to damage, by inserting pressure piece between two secured fixed surfaces of fibre
Inventor: THIEMANN KARL-HEINZ DIPL ING
IPC: G01N3/02
Filed: 1991-04-17
Abstract: To determine the tensile strength of fibres, and esp. ceramic fibres, they are bent and the bending path is measured up to the point of damage through the bending action. The end of the fibre is firmly bonded by adhesive, and the fibre is bent round the bonding point. Or the fibre is secured to two fixed and spaced surfaces, and a pressure piece is inserted into the gap between them, at a defined distance from each surface, to bend the fibre between the surfaces. The process is esp. for silicon oxide fibres in the exhaust gas filters of vehicles, to determine their tensile strength as they are partic. affected by after crystallisation at high temps., attack from oil ash, coating, chemicals and other attacks which lead to splitting. USE/ADVANTAGE - The method is esp. for ceramic fibres in a glow treatment with coating. The technique tests the tensile strength without exerting a pull on the fibres.
Patent DE-4116482-A1 (DE)
Inventor: PETER GUENTER
IPC: F15B1/08
Filed: 1991-05-21
Abstract: The invention concerns a method of measuring the pressure of a gas in a gas accumulator which can be connected up to a hydraulic-fluid circuit and in which the gas is separated from the fluid by a dividing element. When the dividing element (12) is in a given position, the gas pressure corresponding to this position is measured by a pressure sensor (40) located on the fluid side of the element. This makes it possible to check the starting pressure in a gas accumulator without affecting the operational readiness of the accumulator with regard to its associated hydraulic-fluid circuit. The invention also concerns a device for carrying out this method.

Title: Vehicle sensitive seat belt clamping system - uses inertia of two clamping elements to create firm grip
Inventor: BOEHMLER KLAUS
IPC: B60R22/185
Filed: 1991-07-15
Abstract: The vehicle sensitive clamp for a seat belt has two clamping elements (4 24) between which runs a seat belt (2).

Title: Procedure for drying solid materials - includes treating materials with drying medium, e.g. air, whose pressure is varied periodically while at same time material and/or medium is heated
Inventor: STAHL WERNER PROF DR
IPC: F26B7/00
Filed: 1992-04-06
Abstract: In a new procedure for drying solid materials (14), the material is treated with a drying medium under the application of a pressure gradient. The novel feature is that the pressure of the drying medium is varied periodically while at the same time the material and/or the drying medium are/is heated. Pref. the pressure variations may be in the form of pulses. The pressure may be varied between two values in the range 4 to 20 atm, or between 0 and 4 atm. The rate of pressure change is chosen so that the range of pressure variation is not exceeded. Before carrying out the above steps, a constant high pressure may be applied, pref. at 10 to 50 atm. followed by a sudden rapid decompression. The procedure may be used for drying wood, and can be applied to the surface of a piece of wood. The procedure may also be used for drying granular materials and ceramics. The inlet (16) and outlet (18) points for the drying medium are at a distance from each other. The medium and the container (12) in which the material is dried, may be heated. The moisture content of the medium may be progressively reduced during the drying period.
