Patent DE-2707895-A1 (DE)
Title: Building structure settlement damage prevention system - uses compression springs maintaining support of building when foundation drops
Inventor: JUNG JOHANN
IPC: E02D27/34
Filed: 1977-02-24
Abstract: Compression springs are incorporated in a building structure as a means for preventing building damage by mining subsidence. The function of the springs is to permit relative vertical movement between part of the foundation and the rest of the building structure, thus compensating for foundation settlement. The springs are pre-compressed and are installed typically in the cellar walls, the plane of a damp-proof course or other joint intersecting the springs. The compression force in the springs may be adjusted, and the spring modulus chosen so that the expected degree of foundation settlement will not result in serious loss of supporting reaction.

Title: Whorl yarn lap removing tools - are mounted pivotally on vertically displaceable copse changing support for angular displacement from rest to lap removing position
Inventor: KLEIN KONRAD
IPC: D01H1/38
Filed: 1977-02-28
Abstract: Whorl yarn lap removing tools each associated with a whorl in a bank of whorls, are mounted pivotally on the copse changing support for angular displacement by the vertical movement of the support between a resting and operative position, in the latter of which the tool ends act upon the lap formed on the lap former to remove the lap. Used in spinning and twisting machines. Disposition of cleaning tools on the copse changing support which is located below the whorl bank protects the tools after cleaning by e.g., the pneumatic auxiliaries of the copse changing device fron unnecessary soiling.

Title: Sterilised cleaning system for beer and wine storage tanks - uses atomised spray of cleaning and sterilising mixtures directed to nozzles through multiway valve
Inventor: KOCH ALBERT
IPC: B08B9/093
Filed: 1977-04-06
Abstract: The sterilisation system is for cleaning out the entire interior of large storage tanks, particularly thin-walled beer and wine tanks. A sterile gas is fed at a low excess pressure, e.g. 0.3 to 0.5 bars via an initial pipe which links the closed tank to a compressed gas source. The storage tank is provided with at least one nozzle (14) so that first a mixture of cold water and cleaning agent, and then cold water and sterilising agent can be supplied to the tank under high pressure of for example 100 bars. The tank is then sprayed with the aerosol of these mixtures. The fluid flowing down out of the outlet of the tank is then used for a renewed spray and finally an aerosol of sterilised water is used for a last rinse. The nozzle in the tank is connected to the high pressure output of a pressure pump with the input of this pump designed for connection via a first three-way valve to the cleaner side of a sterilisation filter.

Title: Biological effluent treatment - with revolving cages filled with plastic elements in sludge settling tank
Inventor: HEMMING MALCOLM LISLE
IPC: C02F3/08
Filed: 1977-06-29
Abstract: A tank for the biological treatment of effluents contains revolving perforated and partly immersed cages which are filled with plastic packing elements. A chain drive is used to revolve the cages so that the bacteria adhering to the surface of the packing rings are in turn exposed to air and immersed in water. If the packing in the two cages has a different specific surface or the cages revolve at different speeds, the first cage can produce a rough treatment and the second a clarifying treatment. A variation of the depth of immersion is also a ready means for varying the effective specific surface.

Title: Flying object for training - has parts held by gas in aerodynamically favourable position during set period
Inventor: DIESINGER WALTER HELMUT DR ING
IPC: F42B10/48
Filed: 1977-10-05
Abstract: The missile, has two or more parts sliding in relation to each other in the flight direction, and which in a first position give the missile an aerodynamically favourable shape. During a predetermined time period after firing, a restraining force acts on the missile, being exerted by gas present or generated in it. This causes the two parts (1, 2) in conjunction with the aerodynamic resistance forces acting on them, to assume the first and favourable position. The absence of this retaining force causes them to assume a second position less aerodynamically favourable.

Title: Mfg. wedge-shaped metallised coatings on workpieces - by varying speed of spray gun to give greater coating thickness in areas of greater wear
Inventor: HUEHNE ERWIN DIETER
IPC: B23K5/18
Filed: 1978-05-20
Abstract: When workpieces have to be metallised, the surface coating has at times to be thicker towards the places of greater wear. This wedge-shaped facing can be achieved by moving the gun fast at the thin end and gradually more slowly towards the thick end. Alternatively the facing material is fed to the gun at an increasing rate. This produces the desired wedge-shaped surface coating in one pass. It saves time and can be readily automated.
