Patent DE-3923330-A1 (DE)
Inventor: MORIMOTO YASUAKI
IPC: G11B7/09
Filed: 1989-07-14
Abstract: An optical scanning system for a compact disc having a sinusoidal data track radially meandering, at a selected frequency, about the axis of rotation of the disc includes a first laser beam for reading data from the data track. A +1 level laser beam and a -1 level laser beam respectively track the opposite edges of the data track and generate a tracking error signal. The +1 level laser beam and the -1 level laser beam are separated, with respect to the disc, by a distance equal to an odd integer multiple of one half the wavelength corresponding to the selected frequency. The +1 and -1 laser beams are not modulated by the sinusoidal data track and standard tracking circuitry can be used to track the data track.

Patent DE-4001106-A1 (DE)
Inventor: KRUMPHOLZ WOLF-DIETER
IPC: F16B19/02
Filed: 1990-01-17
Abstract: In this torsion-proof flanged connection, the torsional securing and centering of the two halves of the flanged connection (1, 10) is effected in a known manner by means of fitted screws (21) which can be provided with an external tapered region (23A) on their heads (22). The fitted screws (21) are largely free of axial loads since these are transferred to a separate threaded connection (15, 16 and 21C, 21D, respectively). This design is particularly advantageous for planetary gears, where extreme precision has to be maintained even with short structures under high cyclic forces due to torque. The axial gap (26) between ring-gear carrier (10) and planet shaft (5) is kept to a minimum by socket-type screw heads (24). The external flange (10) used as a ring-gear carrier can itself be used for adjusting a bearing (11). In one embodiment with a central threaded connection (15, 16) ensuring axial fixation, this flange is secured against unscrewing by means of fitted screws (21) whose corresponding threaded bores half cut the female as well as the male thread (15, 16). Fitted screws (21) provided with externally tapered heads (23A) and corresponding tapered sleeves (25) or tapered bore-enlargements help avoid errors of centering and the occurence of play in the longer term. With another embodiment, separate axial securing is effected by plain threaded screws (21C) inside the flange (1), the heads of these screws being inserted with radial play into the mounted flange (10).

Title: Single control for cable-steered missile - uses sensor e.g. TV selecting and locking on target
Inventor: SCHARFENBERG GOTTFRIED
IPC: F41G7/32
Filed: 1990-10-29
Abstract: A fixed range flying missile controlled from a central ground location by an optical cable (2) progressively unravelling from an internal coil (3) is steered by a sensor (4) e.g., a TV mounted in the nose area of the missile on a stabilised platform. Once the missile has reached a predetermined level, its trajection is maintained, subject to modifications derived from specific orientation features.

Title: Contactless measurement of external contour of elongated body - involves forming images of sections of body on opto-electronic transducer to determine rapid variations under load
Inventor: DEPPE GERD-JOACHIM DR
IPC: G01B11/16
Filed: 1990-11-23
Abstract: The method of contactlessly measuring the external contours of an elongated body involves forming images of optical sections of the body on an optoelectronic transducer and converting the image of the outer limits of the body standing out from the background into electrical signals from which the dimensions describing the external contours of the body are derived. A number of optical sections distributed along the length of the body are taken in quick succession to detect the variation with time of the contour under load. The signals are directly evaluated by serially reading the voltage state of each line characterising the state of illumination so that the line information reduces to defining the body's edge positions. ADVANTAGE - Improved method enables accurate detection of time variation of external contours of elongated bodies which change rapidly under load.

Title: Structured enzyme membranes prepn. - by charging mixt. of surfactant, enzyme solvent, photopolymer system contg. initiator and polymeric binder to sensor, developing etc.
Inventor: VOPEL THOMAS DIPL CHEM
IPC: C08F2/50
Filed: 1991-02-14
Abstract: The prodn. of structured enzyme membranes for biosensors of precisely controlled permeability comprises adding a surfactant, at least one enzyme and a suitable solvent to a photopolymer system contg. at least one ethylenically unsatd. monomer with at least two gps. which can be radical polymerised, a radical forming photoinitiator or initiator system and a polymeric binder and charging this mixt. to a sensor. The enzyme is enclosed in the polymer system by illumination to form an image and developing and the surfactant is washed out of the polymeric membrane by dissolving in water. USE/ADVANTAGE - The enzyme-contg. microstructured polymer membranes are selectively charged to electrochemical sensors, on which they adhere highly. They have high retention for the immobilised enzyme but low diffusion barriers for analyte and products. Streaks of up to 150 microns breadth can be developed. In smaller structures the scattering of the rays disturbs the enzyme particles. By conditioning the membrane in phosphate buffer, the surfactant is partially washed out of the membrane, which increases permeability. The surfactant also stabilises the suspension. The permeability of the membrane and thus the sensitivity of the amperometric enzyme sensor can be controlled at constant membrane thickness via the surfactant compo
