A number of compression's, at set pressure levels, are made of the patients breast (28). The breast occupies a fixed position on a support (2), above which is an adjustable compression unit (4). For each compression of the breast an ultrasonic image is formed, through the compression unit (4), for the same section of the breast. The compression unit (4) is designed so that the ultrasonic waves pas...

For the preparation of a well-adhering and long-term acting adhesive for dental prostheses, first, on the one hand, sorbitol is blended with carboxymethylcellulose, the resulting mixture is allowed to harden and is comminuted to give a mealy powder and, on the other hand, a solution of ester gum or polyvinyl acetate and ethyl alcohol is prepared, then the preprepared powder is introduced into the ...

A method for the preparation of cellular polymeric products which comprises reacting an organic polyisocyanate with an isocyanate-reactive composition, characterised in that the isocyanate-reactive composition comprises a blowing promoter which is a cyclic urea compound having at least one isocyanate-reactive substituent.

The present invention relates to a process for the preparation of polyurethane foams by reaction of at least one polyisocyanate, optionally in the presence of an expansion agent, with a composition obtained by reaction in an anhydrous medium of a polyurethane foam with a polyether polyol, having a molecular weight comprised between 2000 and 8000, the quality of foam being comprised between 10 and ...

The fastening consists of a retaining jaw (5) to hold one end of the boot on the ski and supported by a body (6) which is fitted to the ski. The jaw can be moved by the boot against a force applied by a spring (11), and the body incorporates a compensating mechanism (16), controlled by an actuator (18). The actuator reduces the return force applied by the spring against the jaw in response to a do...

There is now provided a polyol composition containing a polyol having polyester linkages, an aliphatic or cycloaliphatic C4-C7 hydrocarbon blowing agent, and a polyoxyalkylene polyether monool initiated with a C8-C24 fatty hydrocarbon having one alkylene oxide active hydrogen atom. We have found that the monool emulsifies the C4-C7 blowing agent in the compound having polyester linkages, to form a...

The invention concerns a foil for covering goods carriers such that they can be handled more securely, so replacing the known aluminium cover foils. The foil comprises a plastics matrix which contains a particulate filler, the filler being selected and present in the matrix in such a quantity that the resistance to piercing of the foil is reduced to a limit of less than 450 N/mm (measured on an ap...
