Title: Rotary piston engine rotor seal - has body which flexes in two mutually perpendicular directions and is formed with labyrinth passage allowing lubricant build=up
Inventor: DANZ HERBERT DIPL ING
IPC: F01C19/04
Filed: 1977-01-27
Abstract: The sealing element for a rotary piston engine rotor is able to flex in two mutually perpendicular directions. The seal also has labyrinth seal characteristics, the pressure drop in the seal being achieved by laminar and turbulent flow conditions in labyrinth stages between adjacent sealing elements. On using several elements in this seal it is possible to build up a hydrodynamic lubrication layer. The labyrinth seal can be hence used additionally as lubricant storage for carrying lubricant into the combustion zone.

Title: Maternal heart signal noise removal for ECG signals - by storing shape of interference pulse for subtraction from subsequent pulses
Inventor: NAGEL JOACHIM DIPL PHYS
IPC: H04B15/00
Filed: 1977-04-18
Abstract: The noise reduction system removes the maternal heart signals in abdominally derived foetal-maternal electro-cardiogram signals. It detects interference occuring at intervals and stores its amplitude shape in a memory (5). When further similar interference occurs later in the wanted signal the stored interference is subtracted from it with the correct phase. similar interference signals that are subject to time variations are removed by continually adapting the amplitude shape of the stored signal to the actual shape of the interference signal.

Title: Fireproof suspension contg. resol resin, coke powder - and titanium or zirconium powder, for moulds for casting precision metal parts
Inventor: JASINSKIJ KONSTANTIN KONSTANTI
IPC: B22C1/22
Filed: 1977-10-19
Abstract: A fireproof suspension for the prodn. of casting moulds with fusible models, for casting active metals, contains 10-60 pts. wt. coke, 0.3-5 pts. wt. Ti and/or Zr powder 5-50 pts. wt. resol (esp. phenol) resin(s) as binder, 20-60 pts. wt. organic solvent, and 2-30 pts. (in)organic acid as hardener. The moulds are used for prodn. of precision parts from chemically active metals, e.g. Ti and Zr, for the aircraft and rocket industries, for turbines and jet propulsion devices, for watch cases, bracelets, medical instruments, and supports for bone fractures. The moulds have good resistance to contraction, high mechanical strength, and lower heat conductivity, and are 25-30% cheaper than when graphite is used as filler. The shell strength of the mould is about 17-25 kp/cm2, compared with about 12 kp/cm2 with known compsns. The amt. of filler is reduced by 50-60%, and the moulds can be regenerated and re-used several times. The accuracy of the castings is plus-or-minus 0.3-0.5 mm/100 mm, compared with plus-or-minus 0.6-0.8 mm with known compsns. Thin-walled parts with good surface quality can be produced, e.g. a part with length 30 mm and wall thickness 1.5 mm.

Title: Digital fault monitoring for single pair lines - using sampled oscillator signals and logic converters coupled to alarm stages
Inventor: SCHWERBROCK KLAUS
IPC: H04B3/46
Filed: 1978-03-02
Abstract: A monitoring system for two wire transmission lines in instrumentation systems is used to detect malfunctions, such as short circuits or line breaks. A sender station uses a multivibrator to control the transmission of an oscillator output over two switching gates onto the two wire line, over an isolating stage. Trailing edge detectors connect to an indicator. A receiver station is similarly structured and the signal generating oscillator output is periodically sampled and received. Any line malfunction is indicated by a steady logic level signal to the indicators.

Title: Solar heat collector system - with air separator at junction of stand-pipe to expansion vessel
Inventor: SIKORRA WILFRIED
IPC: F24D17/00
Filed: 1978-03-30
Abstract: Parent patent described a solar heat collector system with a standpipe, an open expansion vessel and a heat exchanger. The standpipe to the expansion vessel is now taken to well below the solar heat collector and is joined to its feed pipe from the heat exchanger through an air separator. This prevents any steam produced at the height of summer when no heat is consumed in the building, from reaching the expansion vessel. It also prevents any air, which may enter the pipe system, from remaining in it and causing severe oxidation.

Title: Yarn tension device - comprising telescopic capsule with independently-mounted spring-loaded end-pieces
Inventor: FRENTZEL-BEYME JOHANNES
IPC: D01H13/10
Filed: 1978-06-29
Abstract: Yarn tensioning device comprises a cylindrical body with two independently spring-loaded cartridge-shaped ends having domed extremities, which is held longitudinally between conically-shaped recesses in a spindle housing. The central component has a considerably greater mass than the end-pieces, sufficient to give the system a period of oscillation greater than 0.1 sec. It may also incorporate a permanent magnet which acts in conjunction with a fixed external magnet to limit the displacement of the mid-section when knots or slubs pass through the device. The two parts of the device operate largely independently of each other, preventing excessive strains being induced in the yarn by the passage of thick places.
