Patent DE-3166473-D1 (DE)
Title: Focus detector
Inventor: WINSLOW JOHN S
IPC: G11B7/08
Filed: 1981-07-13
Granted: 1984-11-08
Abstract: Electro-optical focus detection apparatus for providing a signal indicative of the magnitude and polarity of focus error in a light beam impinging on a surface, such as a recording surface in a recording or playback system. The detector includes a beam splitter for dividing the beam reflected from the recording surface into two reflected beams of equal power, and includes an aperture placed in the path of the two reflected beams. The first reflected beam converges at a focal point before encountering the aperture and the second reflected beam converges at a focal point after encountering the aperture, both beams thereafter impinging upon separate photodetector elements. The aperture reduces the light incident on the photodetectors from both reflected beams, and the apparatus is so configured that the powers of the reflected beams incident on the photodetector elements are identical when the original beam is in focus on the recording surface. When the original beam moves out of focus with the recording surface, both focal points of the reflected beams move in the same direction, to provide an increase in the light falling on one of the photodetector elements and a decrease in light falling on the other, such that the differential output derived from the photodetector elements provides a signal indicative of the magnitude and polarity of the focus error.

Title: Process for the manufacture of a preparation having a high content of phosphatidylcholine from a phosphatide mixture
Inventor: TODT KLAUS HINRICH
IPC: C07F9/10
Filed: 1983-03-22
Granted: 1985-11-07
Abstract: A preparation having a high content of phosphatidylcholine is prepared from a phosphatide mixture by admixing a solution of such a phosphatide mixture in an alcohol having 1-3 caroon atoms with an aqueous or an alcoholic solution of a salt of a bi- or trivalent metal, especially a magnesium salt, and preferably magnesium sulphate, in such an amount that most of the phosphatidylcholine is left in solution whereas most of the other phosphatides are precipitated. The precipitate is separated from the solution and the preparation with a high content of phosphatidylcholine is isolated from the remaining solution by evaporation. The amount of salt to be used is 1-20%, preferably 3-8% by weight relative to the weight of the dry phosphatide mixture. The starting material can be a crude phosphatide mixture, a desugared and/or defatted mixture, a mixture partly enriched with respect to phosphatidylcholine, etc. Preparations with 70% phosphatidylcholine or higher can be obtained with this process.

Title: Method and apparatus for gapping a slide fastener stringer
Inventor: SCHELLING GILBERT
IPC: A44B19/58
Filed: 1983-05-26
Granted: 1986-01-16
Abstract: The two coupling member supporting bands are led between a guide block and two clamping members in a vertical position and having the coupling members located at the lower side. The coupling members are aligned with the path of cutting members by means of a countersupport having two gripping members and positioned relative to the cutting members by means of a scanning apparatus. The clamping members clamp the supporting bands as well as the coupling members which are to be removed. After the coupling members have been clamped by the clamping members, the cutting members sever the coupling members at their foot section and thereafter the cut coupling members are pulled off the supporting band by means of the countersupport and the clamping members. This allows an impeccable cutting of the coupling members and that all cut coupling members can be drawn off the supporting band.

Title: Colour picture manufacturing method and apparatus
Inventor: GIESCHE ERNST
IPC: H04N1/46
Filed: 1983-04-27
Granted: 1987-08-13
Abstract: Apparatus and method for producing qualitatively high-grade color images of originals such as copy masters for multi-color or process printing by exposing chromatic material wherein the originals are scanned point-by-point and line-by-line and the color signals thus obtained are converted into color density values for the chromatic material by means of a correction of color and of gradation. The drive values for a color exposure unit which exposes the chromatic material point-wise and line-wise are generated from the color density values using a linearization process. As a result of signal inversion color positive originals can be recorded as color negatives and vice versa. The exposure process can be matched to every chromatic material independently of the nature of the original to be reproduced and the state of the developing process by means of changing the color density values according to an arbitrarily selectable correction function and by means of signal inversion.

Title: Device for controlling the closure sequence of double doors
Inventor: STORZ REGINA
IPC: E05F5/12
Filed: 1984-06-08
Granted: 1988-06-09
Abstract: Apparatus is described for regulating the closing sequence of double doors with at least one door closer associated with the leading door and a control arrangement which is actuated by the trailing door and which cooperates with the door closer of the leading door. The special feature of the apparatus lies in the fact that the control arrangement consists of a positioning member, which is arranged in the hinge edge region of the trailing door and is movable by the trailing door between first and second switching positions, and of a connection member which is connected to the positioning member. The connection member extends up to the door closer for the leading door and mechanically transmits the movement of the positioning member, to the closer for the leading door. The leading door end of the connecting member acts on a control member which blocks the closing movement of the door closer in one of the two switching positions of the positioning member.

Title: Weldable connecting element for joining or connecting thermoplastic pipes together
Inventor: KUNNECKE WALTER
IPC: B29C65/00
Filed: 1985-08-15
Granted: 1989-02-02
Abstract: The connecting member has a sleeve body and a resistance heating wire embedded therein with terminals to a power supply. By heating the resistance heating wire, a welding area between the sleeve member is plasticized and welded. For checking the weld quantity, an indicator is provided, which comprises a cavity having a piston with an indicator pin movable therein in the welding area. During welding the material which becomes plastic as a result of the welding pressure is forced into the cavity, so that the indicator pin covered prior to welding is forced out through a passage and is consequently visible and tangible. As the travel of the piston is limited by a cover at the end of the cavity and the distance from the bottom of the cavity to the welding area can be selected corresponding to the desired welding pressure, the end position of the exiting indicator pin corresponds to a temperature and pressure range necessary for completely satisfactory welding.
