Title: Space-time geometry modification effect - has gravitative change and uses superimposed transient and eddy fields of radiation sources
Inventor: ZINSSER RUDOLF G
IPC: H02N11/00
Filed: 1975-03-22
Abstract: The altering device changes the space/time geometry effective upon a discrete mass for the production of a modified gravitative effect, in which the rectangular or somewhat rectangular extending fields of an electrical and, preferably, equal-phased, excited magnetic elementary radiation unit are so superimposed that the transient fields and the primary eddy fields of the one elementary radiation unit released by them are orientated in a non-parallel manner to the secondary eddy fields of the other elementary radiation unit. The transformer energy arising from the superimposition of the rectangular fields of the elementary radiation units has an effect from inwards or from outwards on material.

Title: U-rail suspended ceiling-type panel sheet metal clip - has barbs snapping into U-openings and retainers on rectangular metal plate
Inventor: WEIGELT GUNTER ING GRAD
IPC: E04B9/26
Filed: 1975-04-14
Abstract: The sheet metal clip is for use in fixing plates, strips or panels, which may be made of any material, on a system of U-shaped sheet metal rails, with the U-opening facing the plates or other elements, and with inwards-curved bulges on the U shanks, as for instance in ceiling suspension. There is a rectangular sheet metal plate (2), as wide as the gap between the shanks of the U-rails, which have barbed curved sections (3) on their longitudinal ends. These can be snapped into the rails' U-openings, by virtue of their elasticity, to engage with their barbs on the bulges of the rails. The devices (5) for retaining the panels, or other elements, are fitted on the sheet metal plate, on the side facing away from the U-rails.

Title: Removing excess vinyl chloride from PVC - by heating in evacuated mixer with periodic shock-like ventilation
Inventor: KIMMEL HANS
IPC: C08F6/00
Filed: 1975-04-25
Abstract: Excess monomeric vinyl chloride gas is removed from granular PVC with the aid of a closed, evacuated heating mixer, vacuum drum drier or the like, in which the heat is introduced into the container with a heat capacity which without cooling measures would lead to over-heating of the PVC and periodically the mixing container is shock-wise ventilated with cool air for short periods and subsequently again evacuated. The method yields in a short time a better degasification of PVC granules.

Title: Fibre optical system - for measuring optical density of culture medium in fermenter
Inventor: BURLINSON ROBERT
IPC: G01N21/59
Filed: 1975-08-04
Abstract: In an appts. for the measurement of the optical density or fluorescence of a culture of microorganisms in a fermenter, a light beam from an external light source is introduced into a fermentation medium via a first optical fibre light conductor passing through the fermenter wall and then passes from the inner end of the optical fibre through the culture medium to the inner end of a second optical fibre conductor which transmits it out through the fermenter wall where the light is incident on a photo-sensitive detector. More esp., a UV-light beam is transmitted through one of the optical fibre conductors, as a result of which microorganisms growing on the surfaces of the optical components are killed. Replaces the usual method which involves periodic removal of samples, while preventing the growth of organisms on the optical equipment where the measurement is carried out inside the fermenter.

Title: Vehicle propulsion system with variable engine parameters - has flywheel uncoupled from engine to conserve fuel when braked
Inventor: FRIEDRICH WILHELM DR
IPC: F02D17/02
Filed: 1975-10-21
Abstract: To conserve fuel and at the same time decrease noise and harmful exhaust gas emissions, the engine is uncoupled from the flywheel when the propulsion force from the engine is not required. Alternatively each piston could be separately coupled to the crank shaft so that power could be stopped or applied in stages. The piston connecting rods could have variable lengths to decrease the combustion chamber vols. The power and transmission combination may be carried in front of the vehicle to act as a colission damper. To save space when parking, the combination is pivoted inwards to occupy the empty passanger space. The flywheel could be started by either muscular energy or a small electrical motor drawing energy from a storage battery or mains supply.

Title: Variable transmission synchronised gearbox - has individual selector clutches by:passed by full load torque
Inventor: STIEVE KONRAD
IPC: F16H3/089
Filed: 1976-06-18
Abstract: The gear box assembly has spur gear wheels located on parallel shafts and a main shaft (3).
