Process for the production of light rubber vulcanisates

A composition comprises natural or synthetic rubber, a filler which is silica, calcium or aluminium silicate, and an ester of maleic or fumaric acid. The rubber is preferably butadiene-styrene rubber. The alcohol of the ester may be monohydric or polyhydric alcohol and the ester may be a polyester provided that the ester is soluble in the rubber in the quantities added. The ester is preferably mixed with the filler before being added to the rubber.ALSO:Silica, or calcium or aluminium silicate, is mixed with a small proportion, e.g. 0.5-15% by weight, of an ester of maleic or fumaric acid. The term ester includes low molecular weight condensation products of dihydric alcohols with maleic or fumaric acid. The products are used as fillers for rubber (see Division C3).

THERAPEUTIC DEVICE FOR INTRAORAL USE AND METHOD FOR OPERATING SUCH A THERAPEUTIC DEVICE

The invention relates to a therapeutic device for intraoral use for the treatment of teeth grinding and/or tongue thrusting and/or snoring, having: at least two fastening elements (10) for fixing the therapeutic device (1) in place on at least one tooth (4) of an upper jaw and/or lower jaw of a user; at least one sensor element (30) designed and configured to detect compressive loading events and/or sound events and/or vibration events in the oral cavity of the user; at least one stimulation element (50) for stimulating the user when a compressive loading event and/or a sound event and/or a vibration event occurs; and a control and/or regulation unit (40) for the controlled and/or regulated operation of the stimulation element (50) depending on the occurring compressive loading event and/or sound event and/or vibration event; and a power supply.

Improved method for recovering oil from plant seeds

The invention relates to a method for recovering oil from plant seeds, characterized in that a) an aqueous solution, containing one or more cellulolytic, and/or lipolytic, and/or pectinolytic, and/or proteolytic enzyme or enzymes, and or phytases is sprayed onto the seed material; b) the seed material so obtained is supplied in a known manner to a one-step or multistep pressing which optionally is coupled to an extraction step; and c) the oil is recovered in a known manner and optionally processed further; and the use of the method, particularly for the production of food oil or biodiesel.
