Abstract: A hydraulic shock absorber includes a hollow cylinder (10) which defines therein a fluid chamber filled with a working fluid, and a piston (12) which is reciprocally disposed within the fluid chamber and divides the fluid chamber into upper (14) and lower (16) chambers. The piston is formed with fluid passages (20, 22) for establishing fluid communication between the upper and lower chambers. Each of the fluid passages is controlled by a disk valve assembly (24, 50) comprising a plurality of elastic disk plates, so as to introduce the working fluid from one of the upper and lower chambers to the other chamber when fluid pressure in one of the chambers is greater than a predetermined value. The disk valve assembly has a bypassing fluid passage which has a plurality orifices configured so as to gradually decrease fluid pressure and flow velocity of the working fluid passing therethrough.

The hollow profile rods (12) are clamped at their ends on or in the coupling pieces (13) and there form compression rods which are held at least in a pressure-resistant manner. In this arrangement, the horizontal installation plane is intersected centrally and orthogonally by a strut (16) which in each case spaces two tensioning devices (14, 15) of a pair of tensioning devices (ZM) apart from one another in a common vertical plane, and clamps them against one another, which tensioning devices (14, 15) connect to one another in each case two coupling pieces (13) at a point transversely above the module (10).

Abstract: Polymer composites are described which consist of a 0.1-500 micron thick film of a preshaped, surface-forming hydrophilic first polymer A covalently grafted onto an underlaying bulk and structural second polymer B and which are prepared by polymerizing said second polymer B on a substrate which is coated with the hydrophilic first polymer A, said first polymer being able to co-react with the monomers used to prepare the second polymer B. 
     Because of their continuous nature and covalent bonding, the hydrophilic surface films of polymer A adhere tightly to the underlaying polymer B and also conform exactly to the con­figuration of the substrate or mold; polymers with such permanently modified surfaces are useful as biocompatible materials, for instance as contact lenses or as low-friction or non-blocking elastomers, as well as non-fogging, washable and printable polymers. 
     The instant process can also be adopted to prepare the reverse type of polymer composite comprising a hydrophilic polymer with a thin hydrophobic or lipophobic surface. Such composites can be used as membranes, release-rate controlling devices and solvent and soil-resistant polymers.
