Title: Pressure measurement of corrosive, sticky, clogging medium - using tubular membrane conducting medium and transferring pressure to manometer
Inventor: RIKER RUDOLF ING GRAD
IPC: G01L7/02
Filed: 1979-07-21
Abstract: The pressure measurement device is used in conductors or containers of media which are corrosive and tend to stick and clog, e.g. acidic chemicals. It isolates the manometer measurement mechanism from the medium and does not interrupt flow in the conductor. It does not cause turbulence or sedimentation and can be fitted or retrofitted to each conductor without dismantling the conductor. The medium flows through a tubular elastic membrane (5) built into a tube housing (1) so as to be pressure tight. The space (13) between the membrane and the housing is an air or oil chamber which is connected to a conventional manometer (25). The membrane ends have rims (6) fitting in an annular housing recess (3). This sealing arrangement is tensioned by an elastic sleeve (7).

Inventor: LICHT HEINZ ING GRAD
IPC: H01Q1/12
Filed: 1979-09-25
Abstract: Broadcasts from a geostationary satellite are received by a highly directional antenna with a parabolic reflector. The antenna is set to the correct elevation and azimuth by a gauge which is attached to an alignment plate on the side of the reflector installation. This aligns a reference edge (16) on the gauge with the antenna axis. The gauge has a pivoted (11) plate (1) carrying a spirit level (8) and a magnetic compass (3). The plate has a pointer (9) which is set to the satellite elevation on a scale (15) and clamped by a screw (18). The compass is rotated bodily in the plate to set a pointer to the magnetic bearing of the satellite on another scale, and clamped by a screw (7). The antenna is then turned about its axes to centre the spirit level and bring the compass needle to the north/south marks. Fine adjustments of antenna direction are made for maximum received signal and the gauge is removed.

Title: Sea wave driven power generator - has float which is permitted vertical freedom of movement only, in anchored guides
Inventor: GIERL ANTON DR
IPC: F03B13/18
Filed: 1980-07-09
Abstract: The power generator has a control preventing buoyancy and friction forces to affect the float during its way up to the wave crest and down to the wave valley. The shape, dimensions and specific weight of the float matches the type of waves in question. The down movement of the float is directly used for driving a piston pump. The float has only a vertical translation freedom due to firmly anchored guides. The loading force, acting against the float own weight is so rated that the float is first held at the peak of its upper dead centre, before moving down with the wave, due to buoyancy forces. The loading force must be also rated to counteract the friction forces in water. The vertical dimension of the float must by smaller than the double height of the expected weight, while its other dimensions must be rated to exclude contact with water during its downwards movement as much as possible.
