Title: Cutting device for a web winder
Inventor: RAUDASKOSKI VESA
IPC: B65H18/20
Filed: 1991-06-07
Granted: 1994-11-08
Abstract: The invention relates to a cutting device for a web winder.          The cutting device includes a frame construction and a cutting blade, by means of which cutting blade the web in a reel formed on support of carrier drums can be cut off before new winding is started. The cutting device preferably includes an actuator and power transfer members which are operationally connected with the cutting blade of the cutting device.  In this manner, the movement of the actuator is transferred by an intermediate of the power transfer members to the cutting blade so that the cutting blade moves along a curved path.  The cutting blade is thereby movable between a lower position and an upper position, the cutting blade in its lower position being substantially more distant from the carrier drum than in its upper position.

Title: Push-push ring resonator oscillator
Inventor: FIEDZIUSZKO SLAWOMIR J
IPC: H03B5/04
Filed: 1993-11-02
Granted: 2002-10-22
Abstract: A push-push microwave oscillator has two branch oscillators fabricated of a transistor and transmission line elements extending from terminals of the transistor, and a resonator which is fabricated of an annulus of superconductor material and serves to phase lock oscillations of the two branch oscillators. The superconductor material is a composite of a rare earth element and copper oxide such as yttrium-barium-copper oxide. A first transmission line in each of the branch oscillators extends past the resonator with a spacing to provide for electromagnetic coupling between the branch oscillator and the resonator. A second transmission line in each of the branch oscillators has a length equal to approximately one-quarter wavelength of the oscillation frequency to tune the branch oscillator to a common oscillation frequency. A third transmission line in each of the branch oscillators extends towards a junction point to form a summing unit for summing oscillations of the two branch oscillators to provide an output signal of the oscillator. The oscillator is constructed in stripline or microstrip form wherein components of the branch oscillators are coplanar with the resonator and are spaced apart from a ground plane by a dielectric layer of alumina or lanthanum aluminate. Power is extracted at an even multiple of the fundamental frequency, and has a improved accuracy of frequency and reduced phase noise, the latter arising because of a characteristic of the superconductor material wherein its microwave surface resistance increase proportionally with a square of an increase in frequency.

IPC: G01N21/94
Filed: 1993-11-24
Granted: 1999-01-05
Abstract: A method of detecting impurities in a molten resin.          The molten resin is passed through a passage having a window through which light can pass.  Light is emitted from a light source through the window and the molten resin flowing through the passage.  Sensors are used to sense a shadow produced when the light from the light source is interrupted by an impurity contained in the molten resin.          Finally, the size of the impurity is measured from the width of the shadow and the intensity of light of the shadow   Also, judgment is made that if optical signals obtained by detecting the light that has passed through the molten resin indicate that there exist bright areas around a dark area, the dark area is distinguished as a shade of an impurity.  Further, in order to judge the shape of an impurity with high accuracy and record its  image, a plurality of the devices used  in the above method or the device used in the above method and a conventional camera may be used in combination.

Abstract: Novel glycosides, especially steroidal and non--steroidal glycosides, and a novel method of their production, are provided. For the novel method of producing novel glycosides, aglycon compounds are glycosylated with tri-O-acyl glucal using molecular or ionized halogen as a reaction catalyst. In this method an aglycon, which may be a nonsteroid or a steroid having a reactive functional group (e.g., -OH, -SH, -COOH, -NH2, -NHR1) such as a cholesterol, is glycosylated, such that the glycosylation is performed in a single step. For example, if a steroid, the resulting steryl pyranoside, is by oxidation converted to the corresponding 7-ketosteryl di-O--acyl-pyranoside. The latter pyranoside is selectively reduced to provide the corresponding 7-.beta.-hydroxysteryl 2,3--dideoxy-.alpha.-D-erythro-hex-2-enopyranoside. The steroidal and non-steroidal glycosides obtained in this way possess valuable pharmacological properties. In particular, the cholesterol glycoside in vivo exhibits a selective cell--destructive activity on malignant cells which activity is substantially free of side effects on normal cells. The glycosides possess useful properties, especially pharmacological properties which are the same as their respective unglycosylated aglycons. The properties may include a drive-enhancing (stimulating) activity and an anti-inflammatory (immunosuppressive or immunoregulatory) activity.

Abstract: A new method of nondestructive testing of mechanical behaviors of objects under loading has been invented based upon the analysis of spatial and temporal distributions of velocities of deformation and rotation under elastoplastic deformation. In order to carry out this method, optical images of the surface of an object under test are obtained as holograms of a focused image, and diffraction patterns of superimposed images are then formed for a number of consecutive time points spaced with short time intervals. These diffraction patterns are then transformed into wave patterns of space and time distributions of velocities of deformation and rotation along with the respective axes. These distributions are analyzed according to the wave theory of plasticity and strength developed by the present inventors. Wave lengths, amplitudes and velocities of relaxation waves of plastic deformation are determined, and dynamics of these parameters are used to predict the time and point of eventual failure.

Abstract: This invention relates to processes for manufacture of substantially dust-free particles of enzymes by spray-coating solid particulate cores or seeds with fermentation broths containing enzymes.  Fermentation broths containing from 5 % to 100 % total solids as enzyme and 4 % - 55 % total solids content in the broth may be used.  For broths containing 4 % - 31 % total solids, en-zyme and coating agents may be spray-coated so as to achieve a weight gain of 1 % - 24 % w/w aver the initial weight of the cores. For broths with 31 % - 55 % total solids; a corresponding weight gain of 1 % -100 % may be achieved. The enzyme coated cores may be further coated with coating agents: The total dry weight added to the cores ranges from 1 % to 19 % in the absence of coat-ing agents and 1 % to 24 % in the presence of coating agents when the lower range of total solids content is used. The fatal dry weight added to the cares ranges from 1 % to 100 % when the higher range of total solids content is used. These conditions are especially useful in the granulation of enzymes with very high specific activities, so that effective enzyme activity can be provided by adding low amounts of broth solids to the cores. Reduction in added solids is of significant economic benefit in reducing gran-ulation costs.
