Title: Rake cleaner for canals etc. - is truck mounted so rake can pivot between operating and rest position via pulling mechanism
Inventor: SCHMITT WAELTI
IPC: E02B8/02
Filed: 1973-06-29
Abstract: Rake-type cleaning device with a cleaning rake pivot-supported on a truck so that it can pivot between a working position pointing towards the raking and a rest position directed away from the raking, while there is a pulling mechanism to move the truck up and down and to pivot the rake. This pulling mechanism engages on an intermediate component, which can be reciprocated with respect to the rake between two rake-determined end positions. The path which is described by the engagement point of the pulling mechanism, passes below the rake-or intermediate link pivot axis and at its end points lies to one side of the tensile force plane (dead point) passing through the pivot axis. Position and passage of the path and centre of gravity of the intermediate link are so determined to the rake pivot axis that, on overcoming the tension force, the intermediate link is automatically in a position in which the rake is loaded towards its operating position.

Title: Prefabricated concrete components form-locking joint - with interfacing open-fronted tie-bars and bar-shaped double anchor inserted between them
Inventor: KOTULLA BERNHARD DR ING
IPC: E04B1/04
Filed: 1973-09-14
Abstract: For locking concrete slabs or similar load bearing prefabricated components together, as in room-cell unit structures, there are tie-bars in the interfacing joint surfaces, with their openings facing one another. The bar-shaped double anchor for insertion in these has two anchoring sections facing opposite ways. Remaining hollow spaces may be filled with compression mortar, and joint areas on both sides of the double anchor may be screened and sealed by elastic insets. This is simple, cheap, immediately effective and suitable for application to mass-production methods. Conveniently the anchor may be made of steel, suitably galvanised if desired to give protection against rusting. Other suitable material such as plastics may also be used.

Title: Ships propeller shaft seal arrangement - normally inoperative reserve seal brought in service by axial movement of shaft or fixed sleeve
Inventor: ROSSMANN GUENTER
IPC: F16J15/00
Filed: 1973-10-23
Abstract: Operative seal rings engage seal surfaces of a sleeve mounted on the shaft.

Title: Protective current monitor for supply phases - has transformer forming difference between currents in phase line-pair as alarm criterion
Inventor: FEDERA FRITZ DR
IPC: H02H3/347
Filed: 1974-08-23
Abstract: The protective current monitor, for supply phases, measures the difference current per phase or per line formed from the inward ward-flowing and outward-flowing currents. This difference current is passed to a comparator that triggers an alarm if a given level or levels are exceeded. The difference currents are constructed using difference transformers with their toroidal cores encircling each pair of phase lines. The advantage of this protective current monitor lies in its being able ot detect shorts to earth and shorts between phases and in being of the same construction whatever the size and type of load.
