Abstract: A hand-operated injector for inserting a lens into an. eye has a grip body (1) with a lens holder (13) for holding a lens, and a plunger (2) arranged displaceably in the grip body (1) for guided insertion of the lens into the eye. An actuating means (5, 6) for displacing the plunger (2) relative to the grip body (1) is arranged on the plunger (2), which actuating means (5, 6) is rotatable relative to the plunger (2). The injector can thus be rotated through any desired angle, without having to substantially change the position of the hand pressing on the plunger (2), in particular the position of the thumb.

Abstract: In the method for coating substrates the substrates are placed in recesses in a glass-ceramic plate or plates arranged over infrared high-temperature radiators with the surfaces to be coated on the radiators. The substrates are heated from below to the process temperature required for the coating. Subsequently the substrates are removed from the heating device, introduced into a coating chamber and coated. The preheating device for the substrates has two glass-ceramic plates that are placed loosely on top of each other and infrared high-temperature radiators. Substrate receptacles are provided in the glass-ceramic plates by approximately coincident recesses of different size in the plates so that the substrates can be held in close proximately to the radiators during the preheating.

The insert has a third stop means cooperating with the first stop means for defining an extended position of the insert and a fourth stop means coacting with the second stop means for defining a retracted position of the insert. The insert further has a micrometer female thread. A tubular knife holder with a knife for cutting a circular cut into the cornea is mounted in the insert. The knife holder has a micrometer male thread threaded into the female thread and a head. A scale and a marking on the head and on the insert are provided for preselecting a depth of the cut in the extended position of the insert.

Abstract: The reflector for a light, which has a high-pressure gas discharge lamp, has an adherent polymeric coating extending over at least a portion of its outer surface. This polymeric coating contains at least one fluoro-polymer. The coating thickness is from 5 &mgr;m to 200 &mgr;m. A method of making the polymeric coating on the outer surface of the reflector includes powder coating the outer surface of the reflector with the at least one fluoro-polymer and subsequently heat after-treating the reflector with the powder coated outer surface. Alternatively the reflector is coated in a dipping or spraying process and then thermally after-treated. The coated reflector can be used in a headlight or an optical device for projecting data.

Abstract: A device for inserting a lens into an eye has a grip body (1) with a lens holder (13) for holding the lens, and a plunger (2) which can be displaced in the grip body (1) for guided insertion of the lens into the eye. A ball-bearing bush (3) is arranged in the grip body (1), the plunger (2) being mounted so as to be laterally displaceable in this ball-bearing bush (3). This allows the device to be operated using one hand, said device additionally having good slide properties and permitting an at all times guided lateral or rotational movement of the plunger.
