Abstract: Abstract of the Disclosure A wave-shaping circuit which comprises a comparator for comparing the level of a signal reproduced from a magnetic tape on which, for example, PCM signals are recorded with the level of a reference signal, and a D flip-flop circuit for holding an output signal from the comparator for a prescribed period.  Where the reproduced signal has a higher level than the original level of the reference signal, then the reference signal is made to have a higher level than the original level by an output signal from the D flip-flop circuit, that is, an output signal from the comparator.  Where the reproduced signal has a lower level than the original level of a reference signal, then the reference signal is made to have a lower level than the original level by the output signal from the comparator.  As a result, strains occurring at the high density recording are not reproduced.

Abstract: ABSTRACT            PROCESS FOR THE SEPARATE RECOVERY OF MOLYBDENUM AND VANADIUM           The invention relates to a process for recovering and purifying the molybdenum from a solution containing mo-re molybdenum than vanadium.          The process of the invention comprises the step of contacting the solution which contains molybdenum and vana-dium, originally at a pH at least equal to 11 with an excess of an ammonium salt sufficient to precipitate the greatest part of vanadium in the form of solid ammonium vanadate, this excess being yet hot higher than a value such that after precipitation of vanadium, the quantity of ammonium having not reacted with the vanadate would be over a concentration which would account for risks of precipitating also molybde-num which is contained in the liquid phase of the superna-tant.          The molybdenum which is obtained is of industrial grade.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for aligning lumber, especially blocks from which the first pair of cants is removed (hereinafter referred to as blocks), comprising a conveyor for transferring the blocks in longitudinal direction, a measuring station and a microprocessor or equivalent.  Before feeding the blocks into a saw mill, they have to be aligned correctly in order to ascertain a maximum amount of wood products.  In con-ventional apparatuses for aligning blocks, the align-ment is performed on the unsawed surfaces of the block. In practice this leads to errors.  In the present invention the said errors can be eliminated by arran-ging the aligning members to comprise one or several short conveyors located in connection to the conveyor. The short conveyor can be shifted transversally both below and above the level of the conveyor, and it can be given a horizontal adjusting movement impulse according to the adjusting values received from the calculating unit.

Abstract: Abstract Broadband High-Power Microwave Window Assembly A window assembly for a hollow waveguide of circular cross-section, with improved bandwidth and cooling capability for handling high microwave power transmissions over wide frequency ranges t is disclosed. A plate or disc of dielectric of refractive index n1 extends sealingly across the waveguide and has two parallel faces which exhibit a pattern of corrugations. One of these faces is in contact with a dielectric fluid of refractive index n2, and apparatus is provided for cooling and circulating the fluid over said one face.  Each of the corrugations extends into the fluid a distance proportional to the inverse of the geometric mean of the product of the refractive indices n1, n2.  In a preferred embodiment, a second plate is included, separated from the first by a region in which said dielectric fluid is circu-lated, and in which at least both the faces in con-tact with the fluid are corrugated.  The corruga-tions not only result in greatly improved matching over a broad band, but also greatly improved fluid flow and surface contact thereof over said one face, for enhanced cooling and thus power handling capa-bility of the window assembly.

Invention:   WIND-DRIVEN GENERATOR APPRATUS AND METHOD              OF MAKING BLADE SUPPORTS THEREFOR                     Abstract of the Disclosure Wind generator apparatus employs an induction generator with a wind-driven rotor.  Connection of the induction generator to AC power lines is controlled by apparatus that compares generator rpm and line frequency. The rotor blades have a pretwisted, varying-chord inboard portion and an untwisted, constant-chord outboard portion. The blades are self-starting, operate efficiently over a range of wind speeds with constant pitch maintained by a torsional biasing mechanism, and pitch up automatically when the normal rpm operating range is exceeded.  An im-proved blade-supporting spar of low torsional stiffness has an I-beam configuration with filament-wound flanges. A pitch damper prevents torsional oscillations while permitting the blades to pitch up readily.  The rotor, which includes a teetering hub, is free to weather-vane about the axis of a supporting tower, but a yaw damper limits angular velocity.  A guy wire and gin pole arrange-ment stabilizes the tower and permits easy raising and lowering of the tower.

Abstract: METHOD AND APPARATUS FOR SEPARATING FINELY           DIVIDED CATALYST PARTICLES FROM A GAS STREAM            Abstract Catalyst particles suspended in a gas stream (especially the hot cracked oil vapors issuing from the riser of an FCC unit) are separated by subjecting the flowing suspension to a change of direction and permitting the catalyst particles to fall into a stripping zone.  The hot gas stream is then rapidly transferred to a cyclone via a restricted passageway, minimizing the time that the gas is exposed to catalytic reaction temperatures.
