Abstract: The invention relates to an ophthalmic viscoelastic device, comprising at least one viscoelastic polymer, wherein the at least one viscoelastic polymer is covalently bound to at least one phenolic compound. The invention also relates to a method for producing an ophthalmic viscoelastic device, in which at least one phenolic compound is covalently bound to at least one water-soluble, viscoelastic polymer.

Abstract: Arrangement for connecting a drawer frame (12) formed by a metal hallow chamber profile to the facing lateral edge of the associated plate-shaped drawer bottom (10), in which at least in part-regions of its lower end region opposite the end face of the edge of the drawer bottom (10) the drawer frame (12) has in each case a strip-shaped vertical contact web (26) for the lateral end face of the drawer bottom (10), and a supporting leg (28) which engages under the drawer bottom in the proper connection position is bent away from the lower end of the contact web. The supporting leg has integrally projecting from it fixing claws (32) which are pointed or sharpened at their free ends, project over the support surface of the supporting leg (28) and can be pressed into the material of a drawer bottom which is to be fixed. Each supporting leg (28) has at least one elongate punched-out slot (30) which is closed all round in its region between the strip-shaped contact web (26) and its free edge.

Abstract: A drawer slide comprising a guide rail (1) and a drawer rail (10), the rails engaging in each other, the guide rail having an upper guiding web (6), a lower guiding web (5) and a web (4) connecting the upper and lower guiding webs. The drawer rail has an upper rolling web (9) supported on a first track roller (8) in a front end portion of the guide rail and the drawer rail carries a second track roller (11) in a rear end portion thereof, the second track roller rolling between the upper guiding web and the lower guiding web of the guide rail. A device for preventing the drawer rail from being lifted off the guide rail comprises a marginal web (13) consisting of a bent edge portion of the upper rolling web of the drawer rail, and a supporting stop (14) disposed on the connecting web of the guide rail and overlapping the marginal web whereby the supporting stop is adapted to be engaged by the marginal web.

Abstract: The device comprises for each frame (1) a holding member (5) fixed at the front cover (2), which holding member has an aperture that is defined by clamping surfaces of a supporting plate (8) to be fixed at the front cover (2) and a pressure plate (6) connected therewith by means of a clamping screw (7), and whose width can be adjusted by the clamping screw (7) bridging the same, in which aperture the end of the frame (1) can be inserted by means of a lead-in slit (16) for the clamping screw extending therefrom. The lead-in slit (16) of the frame (1) constitutes a connecting link guide for an adapter (14) comprising the female thread for the clamping screw (7) and protruding from the pressure plate (6), and the end of the adapter (14) protrudes into the correspondingly increased lead-in aperture (12) for the clamping screw in the supporting plate (8), where the clamping screw (7) is supported with its head or a washer (18) on the supporting plate (8) outside the edge of the aperture.
