Title: Parking garage moving rail bound approach platforms - on paired vertical axle rollers, with switching locks to open couplings
Inventor: WOEHR SEN OTTO
IPC: E04H6/30
Filed: 1974-11-13
Abstract: The garage incorporates rows of fixed parking-places, and a shared approach strip with movable parking platforms, able to travel along it on a common rail-bound drive, selectively connected together by means of lateral couplings, to create an interval between platforms as entry to the fixed parking places. A rail which can be travelled over, can be subsequently laid on the base along the approach strip, for guidance of the movable platforms, each with two rollers at a lateral interval, rotating about vertical axles. There is a reversible chain drive for the first or last of the set of platforms, and selectively operated switching locks are provided for each fixed parking place, to open the couplings of two adjacent platforms. The moving parking platforms can be subsequently installed, without making holes in the components of the building.

Title: Offshore structure supporting piles load - measured by strain gauges feeding computer to calculate principal moments for oscillograph display
Inventor: LONGREE WOLF-DIETER DR ING
IPC: G01L5/16
Filed: 1975-05-16
Abstract: The total load of a structure, such as an offshore platform, which is supported by piles is determined by measuring the axial forces in the piles by strain gauges. Based on these forces, the moments are calculated which are referred to the origin of an X-Y coordinate system in a horizontal plane. These moments are added to two principal moments which act around the X-axis and Y-axis. The result is compared with the design figure for the moment. This allows a constant supervision of the effect of horizontal forces (wind and waves) and of any eccentric vertical loads. It also furnishes valuable data for future designs of offshore structures which in the past were designed based on assumed factors.

Title: Mechanised reefing system for sails of yachts - uses reefing lines connected to leech of sail and hauled in by powered winches
Inventor: HOHMANN HERBERT
IPC: B63H9/06
Filed: 1976-02-27
Abstract: The mechanised running rigging for sailing vessels has the normal reef points replaced by reefing lines (68, 69) attached to the sail at both ends. The attachment points are so chosen that all lines are the same length. Their bight can thus be taken to a common pulley wheel (70) from which a single rope (71) runs to a drum on a central windlass. Suitably placed guides (72) cause the lines (68, 69) to reef the sail whilst maintaining its shape, when the rop(71) is wound in. From another drum on the same windlass, the sail halyard (35) or halyards are paid out. All lines are thus kept taut at all times. The reefed part of the sail, which may be double (31, 31") with the reefing lines inside, is pulled into a U-shaped cover (52) hung from the mast or stay. Extra lines fixed to the leach of the sail permit it to be pulled completely into the cover, ready for lowering and stowage under cover.
