The process consists in adding water to a resin with high water absorptivity, such as a crosslinked product of isobutylene-maleic anhydride copolymer, leaving the resulting mixture at rest to form a hydrated gel, adding this hydrated gel to a rubber composition including, for example, a rubber modified with a silicone, and subjecting the resulting mixture to an expansion in conditions which are su...

The device has a mechanical resonator with four identical parallel beams (12a - 12d) occupying the corners of a square, solidly attached to a common fastening base and having the same natural frequency in the two directions parallel to the sides of the square. First transducers connected to an excitation circuit keep the beams in vibration in input mode, in defined excitation directions. Second tr...

Process for the production of polymer-bound rubber chemical binder A b s t r a c t Process for the production of polymer-bound rubber chemicals, characterised in that the rubber chemicals and optionally additives are finely dispersed in a low molecular weight polymerisable liquid, polymerisation is then initiated, optionally after adding a further component which reacts with the polymerisable liqu...

A small amount of drinking water is stored at a sufficiently high temperature to avoid a risk of contamination by Legionellae bacteria. A storage vessel (14) receives and stores heated water from a heat exchanger 2, which also supplies room heating equipment, and includes a secondary throughflow heat exchanger in the form of a smooth pipe coil (17) in which the water for consumption is heated by t...

The module has at least one double-sided housing (1) and two single-sided housings (2). Each double sided housing has two metal frames (10) mounted on one side and the other of a metal base (4) which carries a hybrid circuit (5) on a ceramic substrate on which are carried individual components (7) connected to the substrate by wires (8). The single-sided housings are mounted at the ends of the sta...

The press roll or web guide-roll (15 and 4 respectively) has a roll shell (20 and 6 respectively) of fibre-reinforced plastic, on the surface of which a wire layer (7) is wound to form grooves (17) with a predominantly peripheral direction. To guide the guided web of material laterally by means of the web guide-roll (4) and to centre it automatically, the windings (7) on both sides of the roll cen...

Novel derivates of dolastatin of formula (I) in which R<1>, R<2>, A, B, D, E, F, G, K, X, t, u, v, and w have the meanings stated in the description, and the preparation thereof are described. The novel substances have an antineoplastic effect.

The shoulder muscle caul prosthesis comprises a mesh (5) which serves on the one hand to repair and on the other to give permanent reinforcement to the damaged muscle. The mesh is made from inter-woven fibres of a compatible material, partially covered with a layer (7) of a soft moulded material. The friction surface can be made, for instance, from a polymer-based synthetic material which has at l...
