Title: Photoelectric device consisting of an optotransmitter with a transmitting optical system and an optoreceiver with a receiving optical system
Inventor: QUAPIL GERALD DIPL ING
IPC: G02B5/18
Filed: 1993-02-13
Abstract: In known devices of this type, the transmitting and receiving optical system are designed as refractive optical system (lenses). Together with their mounts, the latter require a relatively large overall volume. Moreover, the expenditure on implementation for achieving satisfactory imaging properties is frequently substantial. The novel devices are intended to render possible a reduction in their overall size in conjunction with optimum focusing properties. The optotransmitter (11) radiates coherent or partially coherent light, and the transmitting and/or receiving optical system are implemented at least partially by a diffractive optical system (12, 13). <IMAGE>
Patent DE-4310506-A1 (DE)
Inventor: PAATZ KATHLEEN
IPC: C11D3/386
Filed: 1993-03-31
Abstract: In order to improve the solubility, to increase the storage stability and to reduce enzyme activity losses during production of enzyme granulates suitable to be incorporated into washing or cleaning agents and containing an enzyme and an organic and/or inorganic carrier, a granulation-auxiliary system is used which consists of alkali-carboxymethylcellulose with substitution degrees from 0.5 to 1 and of polyethylene glycol and/or alkyl- or alkenylpolyethoxylate. When more than 2 % by weight alkali-carboxymethylcellulose are contained in the granulates, they contain at least 0.5 % by weight polyethylene glycol with less than 1000 mean molar mass and/or alkyl- or alkenylpolyethoxylate with at least 20 ethoxy groups. The new enzyme granulates have such a high speed of decomposition that when they are used in washing agents the wash bath contains enough enzyme to remove enzymatically removable soil already in the initial phase of machine washing.

Title: Apparatus and production process (spin-coating process) for thin polymer films
IPC: G03F7/16
Filed: 1993-08-14
Abstract: Technical problem/objective Thin polymer films have so far been produced by the spin-coating process directly in air. A disadvantage of this method in the case of polymer solutions is the rate of evaporation of the solvent and the formation of air turbulences, which prevent the production of homogeneous polymer films with a macroscopically birefringent structure. The invention permits the use of high-viscosity polymer solutions with birefringent properties and prevents air turbulences over the substrate. The evaporation rate of the solvent becomes negligible. Solution A conical cap (2), co-rotating in the spin-coating process and forming with a cover (1) a closed chamber over the substrate (8), prevents air turbulences over the said substrate. The evaporation of the solvent from the polymer solution (5) becomes negligible. The use of birefringent polymer solutions thereby permits the production of macroscopic structures in the polymer films. The substrate (8) is fixed either through the cap by threaded pins (7) and nuts (3) or by adhesive. The cap is adhesively bonded or screwed on a sample plate (6), which is fitted on the motor spindle (4). Field of application Production of thin polymer films which have a macroscopic birefringent structure. <IMAGE>

Title: Optical recording medium and also a device and method for recording and reproducing information on or from the same
Inventor: KATAYAMA HIROYUKI
IPC: G11B7/005
Filed: 1994-04-06
Abstract: An optical disc (10) is specified, on which each head section contains only one recording section for address information. This increases the capacity of the memory area in which a user can freely record data. In an optical disc drive, four laser beams (23a-23d) have a fixed positional relationship. On the basis of the address information relating to one head section, as read out by at least one of the laser beams, and also on the basis of the positional relationships between the laser beams, the address information on all the tracks (TR1-TR4) scanned by the laser beams is obtained. Therefore it is possible to record information on the optical disc or reproduce information from the said disc accurately even if the head section in a track cannot be correctly read. <IMAGE>

Patent DE-4424870-A1 (DE)
Inventor: JOHAENNTGEN UWE
IPC: F01K9/00
Filed: 1994-07-14
Abstract: In a process in thermal power stations in which condensers (1a, 1b) are connected in series on the cooling water side to improve efficiency, it is proposed that, with excessively low cooling water inlet temperatures, when the improved efficiency is lost through sub-critical pressure ratios, part of the flow of cooling water adjustable, e.g. using a regulating device (13), be diverted before entering the first condenser (1a) via a by-pass line (12), by-pass said condenser (12) and be remixed with the partial cooling water flow before entering the condenser (1b) through which it has yet to pass. The process of the invention can also be extended to other condensers in order to ensure that there is no obstruction in the flow profile in the allocated turbines or partial turbines owing to the pressure ratios arising in the by-passed and subsequent condensers. The advantage of the improved efficiency is thus retained even with excessively low cooling water inlet temperatures and the pressure ratios in the un-by-passed condensers remain virtually unaffected. The ratio between by-pass partial flow and cooling water partial flow is adequately adjusted or controlled depending on the actual cooling water outlet temperature.
