Abstract: Abstract of the Disclosure The subject of the present invention is a continuous method for the decomposition of a raw-material that contains polysaccharides by means of acid hydrolysis. According to the method, the raw-material is hydrolyzed continuously in one reactor as two steps. In the first step, the hydrolysis is run in the upper part of the reactor in a vapour phase, whereby pentosans are decomposed mainly into furfural, acetic acid, methanol, and acetone, and hexosans are decomposed into disaccharides and trisaccharides. In the second step, the hydrolysis is run in the bottom part of the reactor in a liquid phase, whereby the disaccharides and trisaccharides obtained in the first step are decomposed into monosaccharides and into saccharic and fatty acids.

Abstract: ABSTRACT OF THE DISCLOSURE              A method is provided herein for manufacturing a fishing net including knots formed of a first warp member and a second weft member.  The method includes the following steps:  holding either of the first and second members by an upper hook, that hook being freely rotatable about its own axis.  The other of the first and second members is then moved into a position adjacent the upper hook. The upper hook is then rotated about its axis a half rotation or one and a half rotations to catch the other of the first and second members.  The upper hook is then rotated about its axis a full rotation to form two loops from the first and second members.  The first warp member is now pulled through the two loops and the first member is passed along the underside of a shuttle frame, thereby causing the first warp member to draw the second weft member through the two loops.  The two loops of said first warp member and said second weft member are then released from the upper hook.  Finally, the first warp member and said second weft member are tightly fastened together to form a knot which is less likely to become loose.

Abstract: ABSTRACT OF THE DISCLOSURE           A catadioptric optical system for scanning an object and projecting its image in four modes of operation.  In one mode, a stationary object is scanned by moving mirrors and its conjugate image projected at unity magnification onto a moving image surface.  In a second mode, conjugate distances are varied to project an image at other than unity magnification. In a third mode, the optical system remains stationary and the object is moved relative to it to enable imaging of objects larger than the scan travel of the optics.  In a fourth mode, the optics again remain stationary and an add-reflector is introduced to create a reflection cavity to increase the object conjugate for minified imaging of large moving objects. Mirrors and lens are movable to effect magnification changes.

Abstract: Abstract A narrow mesa region of ?tripe geometry is formed on a GaAs cyrstal substrate.  A crystal layer of higher resistivity than the substrate is located around the mesa region, the top faces of these regions being flush with each other.  On these top faces there is thus formed a light-emitting assembly consisting of several epitaxial growth regions of semiconductor crystal, including an active region for lasing.  Subsequently there is formed a contact isolation region having an opening with the ?ame stripe geometry as the mean region.  Finally, on the contact isolation region there is formed a metal electrode contacting the uppermost layer of the epitaxial growth regions through the stripe-geometry opening.          Current flows from the stripe-shaped portion of the upper electrode to the similar stripe-shaped narrow mesa region in a narrow concentrated path.  As a result the effective lasing region is sufficiently concentrated to enable lasing with a low threshold current.  Furthermore, since insulation films, such as SiO2 films, are not used for contact isolation, and the regions around the active region have sufficiently large area ail the way across the substrate, almost no strain is set up in the semiconductor crystal around the active region thereby assuring long life with stable ?unction.

Abstract: ABSTRACT OF DISCLOSURE         A liquid fuel injection pump for supplying timed charges of fuel to an engine by timed pumping strokes includes an adjustable timing mechanism for changing the timing of the pumping strokes.  The timing mechanism includes an advance piston which is variably positionable in response to two different hydraulic control pressures.  A speed related control pressure operates a servo mechanism associated with the advance piston to provide a component of speed advance.  The reference position of a servo spring associated with the servo mechanism is varied by the second control pressure acting against a piston which mounts the spring and which is biased to a position of relatively advanced timing, thereby to add a component of advance which modifies or supplements the speed advance.  The second control pressure is correlated with engine load and/or acceleration and in one embodiment is derived  from the posi-tioning of the fuel metering means and in another embodiment is derived from the intake manifold air pressure such as that from a turbocharged engine so that the timing is relatively advanced at low loads and during acceleration, and is relatively retarded at higher loads.  A gate controlled by the position of a fuel limiting plunger coacts with the advance piston's servo mechan-ism to prevent advance of the advance piston during engine crank-ing, and maximum fuel delivery per pumping stroke is controlled according to intake manifold air pressure.

Abstract: A Method of Drying a Cardboard or a Paper Web and Drying Device for Applying this Method.        Abstract of the Disclosure.        A method of drying a cardboard or a paper web by passing the wet web supported by a drying band between two moving, nonpermeable surface elements having good heat conducting properties. The surface element contacting the web is subjected to heating and the surface element contacting the drying band is subjected to cooling. Due to the heating of the web the water contained there in is caused to evaporate and the evaporated water is caused to condense into the drying band due to the cooling of the drying band. The water is removed from the drying band after the web and the drying hand have left the surface elements and have been separated from each other.

Abstract: GAS FLOW REGULATING STRUCTURE             ABSTRACT OF THE DISCLOSURE           For controlling the flow of a gas in a duct, a ring which is adapted to be situated in the duct surrounds a predetermined axis which passes through the center of the ring and which is normal to a plane con-taining the ring, this axis coinciding with the duct axis when the ring is situated in the duct.  A plurality of overlapping throttling blades are pivotally carried by the ring and are adapted to be situated therewith in the duct.  These blades define the side surface of a truncated cone and have upstream end defining the base of the cone and downstream ends defining the apex of the truncated cone as well as a throttling aperture through which the gas is adapted to flow.  The cone defined by the throttling blades has an axis which coincides with the above axis.  Thus, when the above ring and blades are situated in a duct it is possible to turn the overlapping throttling blades with respect to the ring so as to con-trol the size of the throttling aperture which defines the apex of the truncated cone.
