Title: Well pump
Inventor: HANTSCHK GUENTHER
IPC: E21B17/02
Filed: 1981-08-14
Abstract: The well pump has a delivery pipe string (18) which is composed of a plurality of delivery pipes (24) coupled together by pipe couplings (30). Within the delivery pipe string (18) a shaft string (52) is arranged which links a drive shaft (50) to a pump rotor (54) and has a plurality of shaft sections (56) which are coupled by shaft couplings (58). The shaft couplings (58) are arranged radially within the pipe couplings (30), are axially supported from below on the pipe couplings (30) to prevent any displacement, and form revolving parts of the bearings for the shaft sections (56). The shaft couplings (58) have a non-circular internal cross-section and accommodate, in an axially displaceable manner, shaft section (56) ends of an accordingly non-round design, the upper shaft section in each case being axially supported from below on a shoulder (62) of the shaft coupling (58), and the lower shaft section having axial play (64). This ensures that the shaft string (52) can be assembled by simple plugging together of the shaft sections (56) with the shaft couplings (58) and can be dismantled just as easily. No adjustment at all is required to ensure that the individual shaft sections (56) and shaft couplings (58) are evenly supported in an axial direction on the pipe couplings (30). <IMAGE>

Title: Small projector for representing the starry sky
Inventor: STRZEMPA-DEPRE MICHAEL
IPC: G09B27/02
Filed: 1982-07-08
Abstract: The projector can be used for didactic purposes, e.g. school, public observatory. The projector shows the starry sky for arbitrary geographical locations and arbitrary times. The diurnal movement of the starry sky can be represented in time lapse. The device consists essentially of three concentrically arranged spheres. From the inside outwards: projection sphere (K1), star sphere (K2, analyser), polarisation sphere (K3). The star sphere is freely rotatable inside the projection sphere. Stars are realised on the star sphere surface by circular holes of different size (magnitude) and colour and imaged by point light lamps (PL) in the centre on the projection sphere, which is sprayed white. Degree grids and figurative representations of the constellations can be faded in and out depending on the mutual position of the star and polarisation spheres. The planets and moon are represented by small individual projectors which are mounted on a plexiglass strip (ecliptic) spanning the star sphere. The positions of the star and polarisation spheres can be varied by geared motors. Rotation pulse transmitters (RIG) transfer changes in position to a logic circuit. This enables all the functions of the small projector to be controlled by computer.
