Abstract: The process separates components of a liquid mixture in which one or more components to be extracted are highly diluted and these components can be precipitated by lowering the temperature. In particular, the process is used to extract hydrocarbons, for example ethanol, from mixtures which have been produced biologically, such as fermentation mixtures and fermentation mashes. …<??>The object of the invention is to design said process in such a way as to make it possible to produce, under economical and low-energy conditions, for example, ethanol even from mixtures which contain only a small percentage of this substance. …<??>It is characterised in that… a) the liquid mixture is subjected to a first pervaporation, with the extraction of a permeate having enriched components,… b) the permeate is divided into portions with low to higher concentrations of the component by means of condensation, and… c) at least one more highly concentrated portion is dehydrated by means of a second pervaporation or distillation.

Abstract: A device (19) sprays liquid onto the vehicle (39), while closely following the general contour of the vehicle (39). The system determines that contour by analyzing and recording patterns of broken light beams when the vehicle (39) passes by an array (37) of photoelectric sensors. The system uses the stored information about the contour of the vehicle (39) to control the movement of a spray bar (17) which contains a set of nozzles (23). The spray bar (17) initially moves with the vehicle (39), spraying the front grille, then, reverses direction, while the vehicle (39) continues to move forward. After having traced the entire contour, the spray bar (17) reverses direction again, now following the vehicle (39) and spraying liquid towards the rear fender, until the washing cycle is complete. The spray bar (17) oscillates axially while spraying. A unique shifting me­chanism (7) adjusts the axial position of the spray bar (17), and thus determines the center of the axial oscillations. The appara­tus is preferably controlled by a microprocessor (150), or its equivalent.

Abstract: A laser beam recording method and apparatus are constituted for recording an image by obtaining a laser beam whose optical intensity is modulated by controlling a drive current for a semiconductor laser on the basis of a light emission level instructing signal corresponding to an image signal, and scanning the laser beam on a photosensitive material. The optical output is stabilized by detecting the optical intensity of the laser beam and feeding back a feedback signal corresponding to the detected optical intensity to the light emission level instructing signal. A filter circuit formed so that the gain gradually increases from near to a cutoff frequency of a circuit for the optical output stabilization toward a higher frequency side is disposed in a stage prior to the circuit for the optical output stabilization. Or, a bias current of a value smaller than the value of the drive current that produces the laser beam of the minimum optical intensity capable of exciting the photosensitive material is always fed to the semiconductor laser.

Abstract: An improved microchannel plate (22) is shown fabricated from tubes formed from at least two types of cladding glass (56,58) and a core glass (54); including a first cladding (56) of partial acid resistant glass and a second, super cladding (58) of high acid resistant glass. The first cladding (56) may surround a hollow core that forms a passage or it may surround a core (54) of low acid resistant glass which is removed by an acid bath to form the passage (32). The second cladding (58) surrounds the first, while the opening of the passage surrounded by the first cladding (56) is tapered by an acid etch that does not affect the second cladding (58). Thus, the ratio of the open area of the passages to their end surface area is controlled only by the removal of the first cladding.

Abstract: The compositions provided by this invention comprise ring-opened polymerized polymers obtained from cycloolefin monomers wherein a portion of said monomer is comprised of high molecular weight, resinous cycloolefin monomers. These resinous cycloolefin monomers provide high heat distortion temperatures without significantly affecting processability when polymerized in a solvent. When ring-opened polymerized cycloolefin monomers and resinous cycloolefin monomers are polymerized in bulk, in a mold, there is no need for processability and molecular weight control. These resinous cycloolefin monomers are obtained by Diels-Alder reaction of cyclopentadiene with cycloolefin monomers and/or olefins. Significant improvements (increases) in glass transition are seen, which correlates with higher heat distortion temperatures. The polymers obtained exhibit glass transition temperatures suitable for automotive and other engineering plastic applications.
