Patent DE-3815317-A1 (DE)
Title: Method for fanning out optical waveguide fibres in a manner without closures
Inventor: BLUEMLE MARTIN
IPC: G02B6/38
Filed: 1988-05-05
Abstract: Through the fanning out without closures the cable is given the required hold as a result of the cable entry which at the same time serves as cable clamp. The fibres are fanned out by the guide sleeve so that twisting of the fibres is ruled out. The splicing operation with its sources of error (splice attenuation) is thus totally obviated.
Patent DE-3816477-A1 (DE)
Inventor: MACMILLAN WILLIAM A
IPC: A61B10/02
Filed: 1988-05-13
Abstract: A device for collecting biological material (e.g. from the cervix) comprises a shaft 10 with a loop-like collection 11 means at one end. The collection means provides a non-cutting, scraping edge to allow collection of the material without cutting. In a preferred embodiment, the collection means retains the material by diverting it into the interior portion of the collection means. The biological material is released from the device by rotation of the shaft or by elution in an appropriate solvent. <IMAGE>

Patent DE-3818509-A1 (DE)
Inventor: WILSON RONALD HARVEY
IPC: H01L23/522
Filed: 1988-05-31
Abstract: A critical temperature process permits the formation of low resistance contact between selectively deposited tungsten (14) and a layer of aluminium or aluminium alloy lying (12) at the bottom of a via opening in a dielectric layer (11) as illustrated in the figure. The process is characterised by depositing the tungsten at a temperature greater than approximately 350 DEG C but not at a temperature so high as to damage said aluminium material. The process herein and the structure formed thereby are particularly useful in the fabrication of micron and submicron sized integrated circuit devices since the problem of depositing electrically conductive material in high aspect ratio via openings is solved. The plug exhibits a specific contact resistance to said aluminium material of less than approximately 2 x 10<-8> ohm-cm<2>. <IMAGE>

Patent DE-3835445-A1 (DE)
Title: Overlying solar window
Inventor: POSPISIL ANTON DIPL ING
IPC: E06B7/28
Filed: 1988-10-15
Abstract: The "classic window" is, in terms of heat, the weakest member in a house. In order to eliminate this weakness, a glass casing is provided over the house window. Diffuse daylight and/or insolation result/results in the formation, within the glass casing, of a heat cushion which prevents heat losses at the house window and contributes to the heating of the rooms. Over-heating in the summer is solved by openings which can be pivoted open. Protection against insolation into the rooms is achieved by built-in roller sunblinds, Venetian blinds or light-tight blinds.

Patent DE-3921061-A1 (DE)
Inventor: BOERNER REINHARD DIPL ING
IPC: G02B30/30
Filed: 1989-06-23
Abstract: An autostereoscopic viewing device with a flat picture screen and a pattern of cylindrical lens portions for producing three dimensional image perceptions without the need for additional optical accessories. The viewing device provides the largest possible freedom of movement of the viewer, whereby the reproduction quality is as uniform as possible and out of focus, cross-talk and other disadvantageous optical effect are greatly reduced. The procedures for making any necessary optical corrections are based on the plane parallel changeable positioning of a flat picture screen relative to an array of cylindrical lens portions. The array of cylindrical lens portions has an increasing thickness as well as a decreasing pitch width when moving from the middle to the vertical side edges. The pixel, or picture strip, size on the picture screen is a constant.

Patent DE-3939292-A1 (DE)
Inventor: HOFFMANN MICHAEL DR
IPC: B60T8/32
Filed: 1989-11-28
Abstract: The proposed control system comprises active or semi-active ride-control and anti-blocking system (ABS) and/or anti-slip control (ASC) components, with common sensors and common data-processing or control circuits. The invention calls for the processing circuits to determine a safety level, and for the control circuits to provide the ABS/ASC components and the ride-control system with control signals as a function of this safety level. These measures enable optimum use to be made of existing sensors and control units, as well as making it particularly simple to allow for the interdependence between road-surface irregularities and steering. A comfortable ride is obtained at all times, while still meeting all safety requirements, and there are also safety and speed benefits for the ABS/ASC system.
