Title: Furnace type energy converter - produces electrical current from waste heat and has alternating voltage generator coupled to piston working on stirling principle
Inventor: VOLKRODT WOLFGANG DR ING
IPC: F02B3/06
Filed: 1979-08-16
Abstract: The oven constructed in the so called cannon fashion, has a hot gas motor flanged to the oven flue and the hot side of the displacement housing extending into the hot space of the flue. The displacement piston, return spring and membrane, acting as the main piston, to which the air cooler, conducting away the waste heat, is coupled mechanically and thermally, form the working motor-like part of the system which is based on the stirling oscillating piston principle. An alternating voltage is therefore induced in the stationary stator, by the linear rotor of the generator, which is coupled to the membrane. If the heat in the oven becomes too high, a sensor control a diverter flap.

Title: Textile element for flexible drive shaft coupling - has series of interleaved figure=of=eight thread coils forming flexible disc
Inventor: STAHL ALFRED
IPC: B29C70/32
Filed: 1979-11-10
Abstract: A flexible-disc drive-shaft coupling is fabricated from a series of threads which are wound around a corresp. number of winding pegs arranged in a circular array around the circumference of a reciprocating disc. Each thread is wound several times in figure-8 fashion around two neighbouring pegs such that the figure-8 turns are interleaved with the adjacent turns to form an annular assembly of coils having a series of bolt-holes corresponding to the positions of the winding pegs, in between which the threads cross alternately over-and under each other. The assembly is encapsulated in a binder matrix to form the flexible disc. The winding can be carried out automatically at high speed without the need for manual intervention. The process gives a flat disc of uniform construction and better quality than manually-fabricated articles.

Title: Borehole probe using X=ray emission esp. for ore exploration - has adjustable shielding to give large back scatter angle
Inventor: LUBCKI ANDRZEJ DIPL PHYS DR
IPC: G01V5/12
Filed: 1979-12-15
Abstract: Borehole probe has a measuring system for using non-dispersive X-ray fluorescence with radiation collimation for element analysis; the measuring system comprises a radiation source, a detector for the X-ray fluorescence and/or Compton scatter radiation and a shield to keep direct radiation away from the detector. The radiation source, detector and shield form a generally cylindrical assembly inside the borehole. Specifically, the shield is composed of two parts forming between them a conical, slit-shaped collimation gap, for conducting the primary radiation from the radiation source; the detector is located inside that part of the shielding which comprises a cylinder and conical apex, and a groove-shaped window in the cylindrical part permits entry of the measuring radiation beam. The other component of the shielding is pref. an adjustable shielding ring with the radiation source located at the centre of its hollow conical surface; the source is also adjustable relative to the shielding. The detector is pref. axially adjustable inside the first component by means of its mounting. Used in the detection and analysis of ores in boreholes. The arrangement makes use of the fact that optimum measurements are obtd. from the sec. radiation when the back scatter angle is approx. 180 deg. rather than 90 deg. as in previous equipment. This is esp. suitable for elements having an atomic number greater than 45.

Title: Sacrificial anode with threaded fixing bushes - which contain signal peg indicating when anode material has been consumed
Inventor: HOESSLE LUDWIG
IPC: C23F13/02
Filed: 1980-01-10
Abstract: In both ends of the anode bar is a threaded bush(6), which can be used to fix the anode bar on the wall of a tank or container, so the anode corrodes in preference to the material of which the tank is made. Bush(6) screws into a blind hole in the anode bar, and contains a sliding piston formed by a peg(7) which pref. carries two O-rings mating with the bore of bush(6). When the anode material has been consumed, the pressurised fluid stored in the tank can enter the bore of bush(6), and thus pushes the peg(7) outwards to provide a warning signal that the anode should be replaced. The movement of peg(7) may be used to create a radio signal via a miniature transmitter, the signal being picked up by a remote receiver. Improvements to the anodes described in 2351566, so a signal is provided when an anode is spent.
