Patent DE-19731226-A1 (DE)
Title: Cathodoluminescence spectrometer for electro-optic instruments
Inventor: KOSCHEK GEORG DR
IPC: G01J3/28
Filed: 1997-07-21
Abstract: The spectrometer for use in electro-optic instruments (8) uses a long-focus ellipsoidal mirror (7) for collection of the cathodoluminescence within the test chamber. This guides the light emitted from the sample (3) direct through a vacuum-proof window (9) in the test chamber wall to the detector without the need for additional optical elements. The position of the ellipsoid mirror is fixed precisely so that the distance between it and the detector is constant. The output signal from the detector, which is a standard monochromator with measuring head, is used for polychromatic or monochromatic cathodoluminescence portrayal and for measurement of the cathodoluminescence spectra.

Inventor: TEUFEL THOMAS
IPC: G06F3/0346
Filed: 1997-08-09
Abstract: The invention concerns a device comprising a movement detector (1) which detects without contact the position of the device parallel to a marked surface (8) in two and/or three dimensions, a distance measuring element which determines without contact, for each detected position value of the movement detector (1), the variation between the movement detector (1) and the marked surface, and a signal processing unit which computes on the basis of the movement detector position signals and of the distance measuring element data capable of being electronically stored related to the marked surface and/or the movement produced by the movement detector. The movement detector (1) is preferably a matrix consisting of optical detecting means arranged side by side in a surface, such as photodiodes or pixels of an image detector. The variation between the image detector and the marked surface is preferably determined by means detecting the time taken by a light signal to travel the distance. Said device is particularly appropriate for position detecting for image reading electronic appliances, as well as for determining without contact the structure of surfaces in medical and dental applications.

Title: Dome-head parts orientation and singling feed comprizes rotation-symmetric smooth-faced body with variably-pitched spiral guide contour facing orienting flat.
Inventor: ALBER THOMAS
IPC: B65G33/04
Filed: 1998-07-08
Abstract: The conveyor body (5) is rotated symmetrically round an axis (4) and has amooth surfce (5') powered round the inclined axis (4). The smooth body surface (5') has a spiralling raised contour (6) and is confronted by a flat (7) which is so arranged relative the body (5) that the vertical projection of a point from the smooth surface to the front of the flat element (7) describes a vertically ascending movement on the flat element (7) as the body rotates. The flat is spaced from the smooth body surface by the height of the spiralling contour (6) and the contour pitch varies along the body such as to increase with increasing distance from the screw etc reservoir (3) and/or from screw feeder. Thus in the area of small pitch difference, this difference at least equals the screw head size as compared with the area of large pitch difference where the difference is the length of the screw at least. The conveyor body is powered by a variable speed motor (9), preferably stepping motor, giving a body rotation speed round axis (4) of 0.05 Hz. The screws are accepted by rail or tube (10) and/or a hole in the main body (1).
