Title: Anti-alcoholism agents contg sulphurized polyunsaturated oils - and pref contg free sulphur which continues to react with the oils
IPC: A61K31/23
Filed: 1975-03-10
Abstract: Agents for treating alcoholism and for eliminating or preventing alcoholic inxotications contain sulphurized polyunsatd. oils (SPO). The agents are produced by heating a polyunsatd. oil (pref. sesame oil) or a fatty acid with sublimed sulphur at above ca 90-130 degrees C until the sulphur has reacted or combined with the oil. The amt. of S used is pref. such as to give an SPI contg. is not 0.1 wt. % S. After cooling to room temp., the final product is pref. sepd. from sulphur crystals which precipitate out during cooling. The SPO may be administered by usual methods, e.g. by injection or orally (as capsules). While products contg. sulphur crystals may be unsuitable for injection, it is advantageous for capsule formulations to contain undissolved S since this continues to react with the polyunsatd. oil. The desire for alcohol by an individual can be reduced in ca a day.

Title: Door lock mechanism for pressure vessels - has radially driven pivoting sectors with chamfered edges mounted on internally threaded hub
IPC: F16J13/18
Filed: 1975-10-27
Abstract: The device holds shut a hinged pressure vessel door and ensures that the pressure loads are evenly reacted around the rim. A number of sectors are driven radially by arms pivoted at one end on the sectors and at the other on an internally threaded hub. It is driven axially by a hand wheel which turns the captive screw on which the hub is mounted. An annular groove is cut inside the lip of the vessel, so that when the sectors are driven outwards, with the door shut, they engage in the groove and lock the door in place. The outside edges of the sectors are chamfered in such a way that locking the door also forces it into the vessel which compresses a ring seal to resist internal pressure.

Title: Cont. stretching of synthetic polymer films, esp. linear polyesters - using contrariwise running cylinders to reduce unsupported length of film (NL120776)
IPC: B29C55/06
Filed: 1976-01-05
Abstract: Synthetic polymer films are stretched lengthways by applying tension to the film as it moves forward continuously, over a stretching zone determined as to its length, by adjacent, cntrariwise-running cylinders, rotating on parallel axes at right angles to the line of motion; the length of the stretching zone measured at right angles to the cylinders being less than the sum of their radii. When the film is heated to its stretching temp., the first contrariwise-running cylinder is also raised to this temp., whilst the second is held at a lower temp. Each cylinder has a surface coating to which the film will not adhere. Longitudinal stretching takes place at high speed without any significant reduction in the film width.
