Title: Balancing device for rotating polishing disc - uses two driven balancing weights with direction reversal obtained using gear train
Inventor: GAPSIS VLADAS-ALGIS ADOLFOVIC
IPC: G01M1/36
Filed: 1979-11-12
Abstract: The device used two weights each comprising a semi-circular disc with a device for rotating them in unison about an axis which varies relative to the axis of a guide ring associated with this device. The latter has two satellite gears rotated about an axis carrying a satellite gear of a rotation reversal device for the weights. The last satellite gear, or the reversal device, cooperates with a gear rotating on a shaft fixed in the housing for the weights coaxial to their rotational axis. This shaft also carries a gear of the rotation device, with a spring- biased wedge located in a groove of the shaft. The numbers of teeth of the gears are chosen to obtain required conversion ratios.

Title: Process for refining heavy oils derived from coal
Inventor: SUNAMI YOSHIHIKO
IPC: C10G21/16
Filed: 1981-03-26
Abstract: The invention relates to a process for refining heavy oil derived from coal, for removal of the quinoline-insoluble substances and with preparation of a hydrocarbon product which is suitable for the preparation of carbon materials. In the process according to the invention, the heavy oil is heated to remove the volatile components which have boiling points in the range from the initial boiling point of the heavy oil to at least 200 DEG C and at most 270 DEG C, a residual heavy oil derived from coal remaining behind. The residual heavy oil derived from coal is mixed with a solvent of the ketone type having a boiling point below 200 DEG C, with formation of an insoluble precipitate (including the quinoline-insoluble substances) and a supernatant liquid. The supernatant liquid is treated to recover the solvent of the ketone type, and the remaining hydrocarbon mixture is readily treated by vacuum distillation, a hydrocarbon product suitable for the preparation of carbon materials being obtained.

Title: Rig for a sailboard
Inventor: HEINRICH KURT ANDREAS
IPC: B63B35/79
Filed: 1981-05-16
Abstract: The present invention with the designation "rig for a sailboard" relates to the rigging required for a sailboard, consisting of a luff mast, a wishbone boom fastened to the luff mast, and a sail guided with its luff on the luff mast and stretched with its top and bottom luff corner, a clew and a head corner between mast and wishbone boom. In contrast to the known rig of M. Darby or even to the Swiss rig, the rig has a sail shape which is fluidically more advantageous and better utilises the wind conditions and the wind speed over water, the air largely flowing in a laminar manner around the entire sail profile and an enlarged sail area at the head being utilised. In this arrangement, the other parts of the rig, in particular the length of the luff mast, are not larger than the parts normally used hitherto. Here, the sail is changed into a rectangular shape enlarging the top area of the sail up to a top edge and reducing the bottom area of the sail at the leech. The centre of gravity of the surface of the sail shape is shifted towards the luff mast and up towards the top-edge mast. Furthermore, the luff mast is extended via a mast knee and a top-edge mast in such a way that the sail guided on the luff mast is freely suspended at the top luff corner and the corner points at the leech between wishbone boom and top-edge mast.
