Title: Cardboard glazing process - using a solvent applied to glazing cylinder to prevent adhesion
Inventor: LEHTINEN JUKKA
IPC: D21G1/00
Filed: 1977-01-28
Abstract: A process for glazing cardboard material by feeding it to a metal plate for pressing.

Title: Heat treatment jig for holding workpieces - where jig is assembled from three sections, each free to expand and contract
Inventor: WEIK BERNHARD
IPC: C21D9/00
Filed: 1977-09-23
Abstract: The jig is immersed in a salt bath or a pot- or shaft-furnace, and is then dipped in oil or water to quench the work-pieces; and the jig is a spider assembled from three straight sections which form six arms spaced at 60 degrees intervals round a central hub. Each of the three sections has a central boss contg. a hole provided with cam profiles; the cams lock into grooves on a profiled with cam profiles; the three holes to make the six-armed spider. The profiled rod locks all three sections together.

Title: Increasing solar radiation heating effect on water - by using foil floating on surface or supported by floats
Inventor: BRODALLA DIETER
IPC: F24J2/04
Filed: 1977-10-06
Abstract: The method of improving the absorption of heat from the sun's rays by the water in a swimming bath, uses a sheet over the surface of the water, this sheet having high absorption properties for the heat from the sun, and reduced reflective properties. The sheet ensures that the radiation is converted into heat by direct contact with the water. The sheet may be buoyant or may have floats attached so that it floats on the surface, or it may be attached to the edge of the swimming bath. The system may be used to improve evaporation so as to increase the concentration of substances in the water.

Title: Crystal pulling device - with hollow seed crystal bar and coaxial sliding drive shaft (CS 15.9.78)
Inventor: APILAT VITALIJ JAKOVLEVITSSH
IPC: C30B15/30
Filed: 1977-12-30
Abstract: A crystal pulling device has a hollow bar carrying the seed crystal. A drive shaft enters the hollow bar coaxially leaving spaces for the circulation of a coolant. A sleeve, which is flanged to the hollow bar, carries a key which can slide in a keyway of the drive shaft to allow an axial motion combined with a rotary motion. This reduces the possible oscillations during the transmission of the rotation from the drive shaft to the seed crystal bar to a minimum.
