Abstract: A cryostat configuration for keeping cryogenic fluids in at least one cryocontainer, comprising an outer shell and a neck tube containing a cold head of a cryocooler, wherein the coldest cold stage of the cold head is disposed in a contact-free manner relative to the neck tube and the cryocontainer, and wherein a cryogenic fluid is located in the neck tube, is characterized in that the neck tube is disposed between the outer shell and a cryocontainer and/or the radiation shield, the neck tube is closed in a gas-tight manner at the end facing the cryocontainer and/or the radiation shield, the neck tube is coupled to the cryocontainer and/or a radiation shield disposed between the cryocontainers or a cryocontainer and the outer shell, via a connection having a good thermal conductivity, the neck tube comprising a fill-in device at an end located at ambient temperature.

Abstract: Lamellar, fibre-reinforced plastic strips can be used to reinforce a linearly expanded or flat construction part having a support function against any bending stress to which it is exposed. The strips are usually applied to the construction from the outside, or from the inside in the case of hollow structures, and fixed by an adhesive. The lamellar strips are pretensed with a tensioning device, treated with adhesive in a pretensed state, and then moved to the area to be treated together with the tension device. The tension device is provisionally fixed to the construction with displaceable fixing devices and pressed against said construction. Thereafter the lamellar strips are pressed against the construction by means of an air bag or air hose until the adhesive has hardened.

Abstract: In order to anchor, reinforce, affix or keep together construction or machine parts, construction members, construction works or parts thereof, or at least to apply a force component, the invention involves a looping anchor or retaining element including several supeposed belt layers or plies.

Abstract: An arrangement and method for reinforcing a structural component utilizes an elongated strip or lamina which is applied to the surface of the structural component and which has at least one end which submerges into a recess in the surface of the component and is anchored in that recess. This has been found to greatly increase the reinforcing effect of the strip on the structure.

Abstract: A conical anchoring system to anchor one or more loaded, stressed or pre-stressed tension elements (9) comprising a conical anchoring casing and an anchor body (7) fitting into the casing and retaining the tension element(s). The boundary surface between the anchor body and the casing wall is substantially designed to allow free sliding. To prevent the tension elements from being torn out of the anchor body or rupturing the anchor body itself, the rigidity of the gradient material forming the anchor body increases from the site of entry of the tension element at the cone, that is from the front zone, to the rear part of the anchor cone. Substantially improved shear distribution along the surface of the tension element(s) is achieved thereby over the case of substantially uniform rigidity of the anchor body.

Abstract: In order to strengthen an elongated or a two-dimensional bearing construction structure (1) against shear forces, at least one pre-stressing means (11) is mounted in a slack or pre-stressed manner on or in the structure cross-section (4) to generate a pre-stressing force directed transversely to the length or to the two-dimensional surface of the structure when this structure is shear-loaded.

Abstract: A guide rail for electronic module supports has at each of the front and rear ends of the guide rail body a latching element for latchable connection with a respective transverse support member, and resilient latching heads or snap-in connector tabs which engage with correspondingly formed apertures in metal strips disposed in the transverse support members. In order to halve the distance between the guide rails to one another as determined by the apertures, there are provided between the latching arms of the latching elements correspondingly shaped separating or divider elements which are selectively insertable in the apertures or on the cross-pieces disposed between the apertures. For the latchable fastening of a connector on the inner rear surface of a rack there is further provided at the rear end of the guide rail body a securing element furnished with a plug.

Abstract: A modular assembly comprising a rack composed of side walls, two front and at least two rear transverse support members for the accommodation of one-tier or two-tier module supports. For the accommodation of the module supports which comprise at least one connector there are provided guide rails which are releasably attached to the transverse support members by means of resilient latching members. The guide rails each comprise securing means for attaching a connector by means of a plug. For securing two connectors there is provided in addition to the securing means of the guide rails a snap-on holder releasably attached to an intermediate transverse support member.
