Title: Linear output circuit for measuring inductances and capacitances - using simple operational amplifiers and alternating voltage signals
Inventor: REUBOLD KURT ING GRAD
IPC: G01R27/26
Filed: 1976-10-09
Abstract: A number of simple circuits are for use in measuring inductances and capacitances. They have output voltages which are linearly dependent on the inductance or capacitance being measured, and they use simple alternating voltage test signals and operational amplifiers. Two basic circuits are used, one for inductances and the other for capacitances. These consist simply of operational amplifiers used in a standard manner with the test elements in the feed forward or feedback positions with a sinusoidal input signal. The output is linear but dependent on the frequency used, and a combined network may be used for either test element with a changeover switch.

Title: Tool for sharpening metal ski edges - has spring loaded file holder pressing cutting surfaces against edges
Inventor: FENDT CHRISTIAN
IPC: A63C11/06
Filed: 1976-11-27
Abstract: A tool for sharpening the edges of metal skis has two file holders (1) each carrying two files (2a) (2b). The files (2a) (2b) are of square cross-section and fit in opposite corners of a square section tube (1) which has a slot at one corner.

One of the file holders (1) has atransverse square bar (10) which fits in the square section tube (9) attached to the opposite file holder. a spring (12) compressed by a knurled nut (13) presses the files (2b) against the ski-edges. The tool is pushed along he ski by the handles (11a) (11b). Clearance between the bar (10) and tube (11) allows the tool to deflect the suit the ski-shape.
Patent DE-2713117-A1 (DE)
Title: Plastics coil former with thin deformable ridges - has ridges on wire receiving surfaces to take=up coil expansion caused by current flow heat generation
Inventor: ANGERMAIER HUGO
IPC: H01F5/02
Filed: 1977-03-24
Abstract: The plastics coil former has thin deformable ridges (4), lying radially across the inner surfaces of the coil former wire receiving surfaces. These ridges deform when the coil expands axially due to temperature changes. Thus the system prevents the force of the heat expansion to be transferred to the flanges, where it could cause fracture. The assembled coil can, therefore, withstand much higher temperatures. The ridges may have various cross sections, such as triangular, semi-circular etc.
Patent DE-2713807-A1 (DE)
Title: Tool for tightening difficult access nuts or bolts - has chain driven sprockets carried in rigid housing shaped to fit required space
Inventor: SANDER HEINRICH
IPC: B25J1/02
Filed: 1977-03-29
Abstract: The tool is for tightening nuts or bolts, which are in positions which are inaccessible to ordinary spanners, consists of a rigid housing of sheet metal (1). Each end of the housing has a bearing for a sprocket wheel and the two sprockets are connected by a chain. The spindle of each sprocket (6) has a square hole (2) (4). One of the square holes is fitted over the head of the bolt or used with suitable adaptor whilst a square ended spanner is applied to the other hole. When necessary the housing can be curved with jockey sprockets to guide the chain. Another variation of the idea uses a cardan shaft and gears to transmit the motion from spanner to nut or bolt.

Title: Solvent recovery plant for drier to prevent explosions - uses purging gas for solvent vapour cooled by liquid solvent
Inventor: LINDE ROBERT VON DIPL ING
IPC: F26B21/14
Filed: 1977-04-29
Abstract: The solvent recovery plant is drier operated with low oxygen content purging gas. The drying process can be carried out as batch process and the solvent concentrations can be varied in the drying process. It is used with volatile organic solvents or impregnation materials, and prevents formation of explosive mixtures in inflammable solvent and air. The main part of the purging gas is coded to the temperature below the dew point of the solvent. The condensed solvent is subsequently supplied into the drying chamber. Part of the purging gas removed from the drying process is removed from the process after the separation of solvent. The purging gas loaded with solvent vapour is brought in a cooler into direct contact with cold liquid solvent.

Title: Absorption refrigeration circuit using solar energy - providing continuous cooling by isolating high and low pressure sides by valves and storing refrigerant
Inventor: WILLE WERNER
IPC: F25B15/04
Filed: 1977-05-04
Abstract: Absorption refrigeration circuit has a high pressure section contg. condenser and a boiler and a low pressure section containing an evaporator and absorber. Both sections can be isolated from each other by means of separation values. The high pressure section consists of store for the refrigerant after the condenser while the low pressure side has a storage for solvent before the absorber and a storage for refrigerant rich liquid after it. Two values are located either side of the solvent storage, one being on the inlet line and one in the run off line. The values can be at least partially operated as control or throttling values. The store for solvent should be mounted above the absorber, while the refrigerant store is connected to the boiler via. a pump. Circuit is for use on systems where continuous refrigeration is required but the heat source is intermittent esp. with solar energy recovery systems.

Title: Thermally insulated cantilever beam for construction of balconies - features glass-fibre reinforced polyamide or polyethylene terephthalate bearing pads
Inventor: GARTNER FRITZ DR ING
IPC: E04B2/96
Filed: 1977-07-13
Abstract: The parent patent claims an arrangement for mounting cantilevers in construction of balconies at facades which have an inteior, insulated zone, and an exterior zone free of thermally conductive regions. The insulated zone is part of the load-bearing section of the fascade and made up to hollow posts and struts. The balconies are associated with the exterior zone and fastened to the load-bearing part of the fascade by means of the cantilevers each of which engages openings in the load-bearing parts of the fascade, leading a gap to be filled with thermal insulation. In this improvement the part of the cantilever engaging the opening has a vertical extension which bears upon a vertical inner wall of the load-bearing part and is also thermally insulated against it. Glass-fibre-reinforced polyamide or polyethylene terephthalate support pads are associated with the extension.

Title: Permanently marked soap cake mfr. - by combining raised lettering on one strand with hollow lettering on other strand
Inventor: JOHANNSEN FRED ING GRAD
IPC: C11D13/18
Filed: 1977-10-12
Abstract: The Parent Patent described a system of producing multicoloured pieces of soap. Two or more strands of soap are passed through rolls which produce a pattern of meshing male and female letters for a brand name or a logo. The strands are joined in the fashion of a sliding clasp fastener to the final size and are cut or pressed to shape. The lettering remains visible throughout the life of a piece of soap. This is a simpler process than extrusion in the form of letters.

Title: Detoxication of barium ferrite magnet scrap - by adding sodium sulphate to aq. sludge of scrap, to produce insol. barium sulphate
Inventor: STEINGROEVER E DR
IPC: C04B35/26
Filed: 1978-05-05
Abstract: The scrap is treated with sulphate ions so that the water-soluble barium cpds. in the scrap are converted to insol. BaSO4, and the sulphate ions are pref. obtd. by adding sodium sulphate to the scrap. The magnets are made starting from BaCO3 and Fe2O3, the scrap occurs at many prodn. stages, e.g. after mixing and milling the raw materials or grinding the finished magnets. The scrap generally exists as an aq. sludge contg. BaCO3 which has solubility in water of ca. 20 mg/l and is toxic, and should not enter the drains. By adding Na2SO4, the Ba cpds. are converted to BaSO4 which has solubility in water of only ca. 2.3 mg/l. Other sulphates or H2SO4 can be used instead of Na2SO4.

Title: Treating waste sludge contg. calcium sulphite and sulphate - includes calcining part of dewatered sludge and adding to remainder for disposal
Inventor: VALIGA RICHARD E
IPC: C04B11/26
Filed: 1978-08-01
Abstract: Inorganic waste sludge contg. CaSO4 and/or CaSO3 and 30 wt% CaSO3 is hardened by partially dewatering the sludge, withdrawing part (1-90 wt %) of the thickened sludge which is then calcined at 250-650 degrees C. After withdrawing more thickened sludge (10-99 wt % solids) the remaining partially dewatered sludge is mixed with the calcined portion. Used for treating the aq. sludge from an alkaline desulphurising unit in a combustion plant. The proess eliminates the step of oxidising the sludge in the scrubber with metal oxide catalysts and a stabilised prod. is formed which is used as a landfill or a commercial prod.
