Patent DE-4225056-A1 (DE)
Inventor: ANDERSON THOMAS R
IPC: H03M1/34
Filed: 1992-07-29
Abstract: An electronic comparator comprises multiple selectable differential-preamplifier stages (C1-Cn) connected to common load resistors (R1-Rn) and latch stages (460). The input to the comparator array can be selectively switched among the available differential preamplifiers (P1a-Pna and P1b-Pnb) and the differential output resulting therefrom is then fed to the common latch stages (460). In one embodiment the switching between preamplifiers is obtained by bias current steering between them according to a select signal (V1SEL, V2SEL) affecting the bias current path. This can be accomplished without additional bias current requirements because the same current is steered to the active preamplifier stage. In another embodiment, each of the multiple preamplifier stages is provided with its own bias current and the switching is performed at the output of the preamplifier devices. This configuration results in a higher speed of switching because all alternative preamplifiers are always active. <IMAGE>

Title: Dipped-beam headlamp for vehicles
Inventor: BERTLING JOHANNES-GERHARD DIPL
IPC: F21V7/00
Filed: 1993-03-06
Abstract: The headlamp has a reflector (10) which reflects the light, emitted by a light source, in the form of a light bundle which is essentially produced without any optically effective elements, on a cover disc on a measurement screen (16) arranged in front of the vehicle an illuminance distribution (illumination level distribution) (18) having an upper light/dark boundary (20). The light/dark boundary (20) has on the one traffic side a horizontal section (21) and on the other traffic side an inclined section (22). For changing over the headlamp between right-hand traffic and left-hand traffic, the reflector (10) can be pivoted about its optical axis. In the position for right-hand traffic, that section (21) of the light/dark boundary (20) which is located to the left of the vertical central plane (VV) of the measurement screen (16) is arranged horizontally and that section (22) of the light/dark boundary (20) which is located to the right of the vertical central plane (VV) is arranged in an inclined manner. In the position for left-hand traffic, the reflector (10) is pivoted clockwise, seen from the rear side of the reflector, relative to the position for right-hand traffic so that that section (21) of the light/dark boundary (20) which is located to the left of the vertical central plane (VV) is inclined and the right-hand section (22) of the light/dark boundary is arranged horizontally. <IMAGE>

Patent DE-4308336-A1 (DE)
Title: Multicolumnar heater
Inventor: REISERER WERNER
IPC: F28F9/26
Filed: 1993-03-16
Abstract: The invention relates to multi-columnar heaters which are assembled from a plurality of elements. In known heaters, it is necessary during installation to take account respectively of right-hand and left-hand connection, and in the case of an envisaged symmetrical arrangement of the multielement heater the summation of the manufacturing tolerances of the individual elements and the associated difference in length of the heater mean that this symmetry is no longer guaranteed. The novel heater is intended to render it possible for the manufacturing tolerances to be optically compensated, in particular in the case of an envisaged symmetrical arrangement, and for the preassembly of pipes to be further simplified. In accordance with the features, the connections of feed and return (F/R) can be arranged on any arbitrary element of the heater. The feed (F) is connected via a connecting piece (7) arranged in the lower boss (6) to one of the end elements (2), thus producing a forced flow from the connection of the feed to this end element. Given a central arrangement of the connections of the feed and return (F/R) to the central elements of the heater, it is no longer necessary to take account of right-hand and left-hand connection, and as a result a substantial simplification of the preassembly is possible. It is furthermore advantageous that particularly in the case of a required symmetrical arrangement of the heaters, e.g. in the case of installation in niches, the deviations in length occurring due to manufacturing tolerances can be optically compensated. <IMAGE>

Title: Device for splitting a high-power laser beam into two or four individual beams
Inventor: MOESTA KURT THOMAS DR MED
IPC: G02B6/28
Filed: 1993-04-11
Abstract: In the splitting of high-power laser beams, especially for medical applications, no loss factor, uniformity of the splitting and reliability are important. In the case of known beam splitters, the optical components are adjusted with respect to one another individually, and individual components are mechanically pivoted in in order to switch between different splitting rates. The adjustments are expensive and the reliability is low. It is intended for the new device to make do without adjustments and without moving parts. Three commercially available beam-splitter cubes are pressed against one another, for example by spring pressure. By exploiting the extreme angular precision of these optical components, the beam-splitting surfaces are therefore exactly aligned in the interior of the cubes. The orthogonal orientation of the beam-splitting planes produces an equally long beam path for all beam components. Switching between halving and quartering is carried out by changing over the input fibre to a second input port, so that only one cube lies in the beam path. The device is suitable for laser-beam splitting, in particular in the medical field.
