Abstract: The invention concerns a bending device (10) comprising two shaping dies (12, 14) with shaping chambers (22, 24) in order to round a sheet bar (26) about a core (16). The peripheral lengths of the two shaping chambers (22, 24) are each longer than half the bushing circumference. During a pre-shaping step, the core (16) penetrates a first chamber (22) by a depth which is greater than the bushing radius. The sheet bar (26) is thus shaped in the form of a U. In an intermediate shaping stage, an auxiliary core (18) is placed on the core (16) such that, as the second shaping die (14) moves downwards, only the end of the U-legs of the sheet bar blank (26) are shaped arcuately. When the auxiliary core (18) and part (20) of the first shaping die (12) have been removed, the final bushing shaping process occurs, in which the second shaping die (14) likewise travels over the center of the bushing. The three-stage bending method enables a bushing to be rounded highly accurately and carefully.

Abstract: A connector for attachment to a coaxial cable having an annular corrugated outer cable conductor, includes a connector head having a threaded portion and defining a ring surface for establishing a contact from inside with an end zone of an outer cable conductor. The outer cable conductor is enclosed by a contact sleeve which has a plurality of radially resilient segments. Surrounding the contact sleeve is a clamping bush which is so threadably engageable with the connector head along a predetermined clamping path, until an end zone of the outer cable conductor, which projects beyond an end face of the contact sleeve, is urged against the contact surface of the connector head. The clamping path of the clamping bush is subdivided in two sections to define an indexing mechanism, with the first section corresponding to a preassembled state of the connector, and with the second section commensurate with a fully assembled connector onto the connecting end of the cable.

The inner bowl is secured to the housing body at opposite end faces of the housing body and is formed for discharge of solids and liquids with connection ports which extend radially with respect to an axis of rotation of the centrifuge. The outer housing body has opposite axial ends formed with access openings for insertion of a rotor and a transmission into the interior space of the inner bowl.

Abstract: An electromotive linear drive mechanism, in particular a drive mechanism for a body of furniture, includes an electric motor having an output journal and a rotating spindle which has mounted thereon a nut, secured against rotation. The nut is operatively connected to the body of furniture, for movement in longitudinal direction of the spindle when the spindle rotates.

Abstract: The invention relates to a type of radioimmuno-conjugates where the &agr;-radiators or the &bgr;-radiators are stably coupled to the antibody with or without the use of a complex-forming agent and wherein the radioisotope is not iodine and wherein the &bgr;-radiators are Yttrium-90, Rhenium-188, Rhenium-186, Copper-67, Holmium-166 and Samarium-153 and the &agr;-radiators are Astatine-211 or Bismuth-212 and wherein the MAb-moiety of the conjugate is derived either from the mouse, a human or other mammal and which can be either intact, fragmented, humanized or recombinantly manipulated. Furthermore, the invention relates to radioimmuno-conjugates where the MAb binds onto an extracellular antigen, which preferentially appears on cells of the haematopoietic system or where the MAb binds to an antigen at the surface of granulocytes or granulocyte-precursors, or both of these cell types, or were the MAb moiety of the conjugate binds onto an epitope or epitopes of CD 66, respectively CD 66 a, b, c and e.

Abstract: A method for determining data for adapting a reflective surface to a desired surface, includes the steps of determining spatial co-ordinates of a multiple number of points of a surface and entering the determined spatial co-ordinates into a computer as a data record. Recorded in the computer are then shape and/or position of a desired surface, with the shape and/or position of the desired surface being variable. The computer calculates for the multiple number of points on the surface the spacing to the desired surface. The spatial co-ordinates and spacings of the multiple number of points are then outputted as a data record for adjusting the surface. By simulating the treatment process on the computer in advance, it is possible to select the optimal treatment process and to eliminate regional unevenness on the cornea.

Abstract: To fasten an object (8) to a surface (4) such as in a booklet, the object (8) is fastened to the surface (4) which is subsequently, optionally, bound like a page into a booklet. The time-consuming action of inserting the objects (8) into bags and fastening the bags to the predetermined pages of the booklet is thus avoided. It is consequently simple and economical to carry out the method according to the invention.

A contact sleeve is fitted over the outer cable conductor and has a plurality of axial slits extending from its head portion proximate end to form a plurality of radially resilient segments. Interacting with the head portion is a clamping member which surrounds the contact sleeve and travels along a clamping path for loading the segments of the contact sleeve in a clamping direction, thereby clamping the end portion of the outer cable conductor against the clamping surface of the head portion.

Abstract: In this method, the refraction performance is either measured along the path of rays (5-7) for a multitude of ray paths which are distributed across a surface, each path originating from one point (P), or is given based on empirically established values. Afterwards the distances of the incident rays between the surfaces intersected by the path of rays are measured along the path or are given based on empirically established values, and the required shape of at least one surface intersected by the paths of rays is calculated based on those values so that the paths of rays intersect in one point as accurately as possible. Based on the values derived in this way optical fittings (3) can be calculated which can be placed on the cornea surface (8-10), inserted into the inner cornea, attached to the anterior section (11) of the eye and inserted into the inner part of the eye in order to simulate arithmetically all measures that change the refraction power of the eye before the measure is actually implemented.
