Title: Beading formed on thermoplast pipe socket - using internal pair and external pair of eccentrics for adjustment
Inventor: HERMANS INGRID M A C
IPC: B29C57/04
Filed: 1972-12-20
Abstract: The Parent Patent describes an appts. for forming a socket on the end of a thermoplastics pipe, where the socket has a circumferential beading; the appts. comprises an outer mould and an inner forming ring fitted internally with a pair of eccentrics enabling the eccentricity of the inner forming ring to be varied; this pair of eccentrics, when the desired adjustment has been made, is rotated together with the inner forming ring so that in its circular motion it forms the beading against the outer mould. In this addition, the outer mould is itself constituted of an outer forming ring and a pair of eccentrics outside it; this outer pair of eccentrics is adjusted to the same eccentricity as the inner pair of eccentrics; the outer pair of eccentrics and inner pair of eccentrics are rotationally driven at the same speed, thus causing an eccentric motion in the outer and inner forming rings to produce the beading.

Title: Pilot frequency controlled TV reception - involves level controllers with frequency dependence and independence reduce level variation
Inventor: DOOVEN LUC DEN
IPC: H04B3/10
Filed: 1973-07-24
Abstract: The system is used for communal TV reception using amplifier stages with interposed level controllers responding to different pilot frequencies.

Title: Container support frame for lash ship - secures several containers for easy loading onto lighter from mother ship
IPC: B63B25/22
Filed: 1973-12-01
Abstract: The LASH ship accepts its compliment of lighters as normal while extra cargo is stacked on the deck in the form of containers. The containers are assembled on rectangular frames with vertical posts at the corners so that two frames can be stacked over each other. The frames enable the ship to be loaded/unloaded rapidly, as is required by a LASH system.

Title: Accumulator cell connection by welding and riveting - uses lead rivets in holes in adjacent plate heads
Inventor: HEMMER WULF-HINRICH
IPC: H01M50/529
Filed: 1974-04-25
Abstract: The production of cell connections through the cell walls of a multi-cell accumulator as in 1796151 involves the use of connecting heads fastened together via tip-stretched lugs by resistance welding. A sealing ring surrounds the lugs and is butted against the cell wall. Before the insertion of the plate block into the cells the connecting heads have holes of small bore drilled in them. After insertion of the plate blocks a rivet made of lead is inserted into the holes and its free end is shaped to a closing head. The time length of the applied pressure, of the current flow are so chosen that with the welding of the connecting heads formation of a proper rivetted joint occurs.
