Abstract: ABSTRACT OF THE DISCLOSURE      A microorganism strain B-0781 belonging to the genus Pseudomonas isolated from a soil sample from an onion field in Japan, produces a novel enzyme nucleoside oxidase having substrate specificity on various nucleosides and enzyme action to catalyze enzymatic reactions involving various nucleosides.  The novel nucleoside oxidase is produced by culturing a nucleoside-oxidase-producing microorganism belonging to the genus Pseudomonas in a nutrient medium containing assimilable carbon and nitrogen and inorganic salt, and isolating the thus-formed nucleoside oxidase from the cultured cells.  Various nucleoside-5'-carboxylic acids can be produced, by incubating the novel nucleoside oxidase with a nucleoside having a 5'-hydroxy-methyl group, in an aqueous medium under aerobic conditions, and isolating the thus-formed nucleoside-5'-carboxylic acid from the incubation medium.  Assay methods for nucleosides in liquid samples are provided, which comprise incubating the sample with nucleoside oxidase, thereby consuming oxygen and generating hydrogen peroxide and nucleoside-5'-carboxylic acid by acting on nucleoside, and quantitatively determining consumed oxygen or liberated hydrogen peroxide. A kit for nucleoside assay is provided, which contains the recited ingredients.

Abstract: MODULATED DIFFUSER PUMP                Abstract of the Invention This invention relates to a fully modulatable centrifugal pump capable of handling a fluid containing solid contaminant particles and minimizing the temperature rise of the pumped fluid.  The pump is of the type that includes an impeller to propel the fluid through a radial outlet to a diffuser which includes a plurality of diffuser passages.  The improvement is comprised of the following cooperative combination which includes rotatably mounted valve elements passing, in part, through the diffuser and across the diffuser passages.  Each of the valve elements have a port therethrough to variably selectively allow fluid passage therethrough upon rotation of the valve element.       A driving arrangement is coupled to each of the valve elements to thereby affect a yieldable rotation of the valve elements in one direction to progressively reduce the opening of the valve element port to the diffuser passage.  The aforementioned driving arrangement is also drivingly coupled to the valve elements to provide a direct mechanical coupling to the valve element to thereby affect a nonyieldable rotation of the valve element in an opposite direction to increase the opening of the valve port to the diffuser passage, to thereby ensure that contaminant particles that lodge between a portion of said valve port and the diffuser passage and interrupt movement of one or more valve element port closings do not prevent the remaining valve port elements from closing.  During the opposite rotation of the valve elements there is a direct mechanical drive that ensures the opening of the valve port to thereby release the contaminant particle and allow passage of the particle from the valve element and the diffuser.

By means of an amplitude discriminator having two threshold values cor-responding to the two amplitudes of the actuating signal for deflecting the transducer to its two extreme positions, the actuating signal is detected and when the threshold values are exceeded an additional change-over if the track selection signal generation is initiated, which continues until the transducer can guide the playback head along the tracks without reaching one of its extreme positions.

Abstract: Abstract of the Disclosure A bottle single filer for combining bottles fed in a plurality of rows on an inlet conveyor to a single row on an outlet conveyor, has a plurality of oblong separators, which are controlled so as to be movable through a closed path in which they extend obliquely across the inlet conveyor in parallel with the transverse rows of bottles on it.  At a specific location in this path the individual separator moves down between two bottle rows which it follows until the bottles contact and slide along a barrier, which is formed by a transfer section of one side rail and forms a smaller angle with the transport direction than the separators, the bottles being pushed on to the outlet conveyor along said barrier.  In connection with the side rails the separators ensure that only one row of bottles at a time can pass, to thereby obviate bridge formation and jamming.  This also reduces the risk of bottle collision and thus the noise level.

Abstract: SCISSORS WITH CUSHIONED STOP             ABSTRACT OF THE DISCLOSURE          First and second metal blades made from uniform thickness stock are fashioned into scissors which may be disposable suture scissors.  Each of the blades is stamped from sheet metal, they are pivoted together, and handles extend in the opposite direction from cutting edges on the blades.  Resilient means is provided by the handles being resilient and stop means are provided to limit the closed position of the cutting edges to prevent overriding, namely overclosing, of the cutting edges.  The stop means includes first and second stop surfaces integral with the first and second blades, respectively.  The stop surfaces are close to the pivot relative to the length of the handles, the blades have only frictional opposition to movement until the stop surfaces engage, and then the subsequent stressing of the resilient means establishes a cushioned stop of movement of the handles without any further movement of the cutting edges past the fully closed condition.  The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: Insulated Connector Sheet Abstract Insulated sheet material useful for making bonded electrical connections, especially to sets of small side-by-side terminal pads.  In one typical form, the sheet material is an elongated tape comprising an elongated insulating web; a plurality of narrow spaced parallel elongated electrically conductive stripes on the web; electrically conductive adhesive disposed over the stripes comprising a layer of adhesive material in which are dispersed a monolayer of rather thick electrically conductive particles; and a thin electrically insulating layer disposed over the conductive adhesive and which is non-tacky or poorly tacky at room temperature, provides high electrical resistance throught the layer to the conductive particles, softens to an adhesive and flowable condition upon heating to an elevated temperature, and upon cooling to room temperature assumes a firm and substantially nonflowable condition.  Such a connector tape is readily handleable and free from conductive bonding at room temperature but when laid over a set of adjacent spaced terminal pads with the electrically conductive stripes in registry with the pads, and pressed and heated, the conductive particles penetrate through the insulating layer to make electrical connection to the pads.

Abstract: LINEAR MOTOR SHUTTLING SYSTEM                         Abstract of the Disclosure A linear motor shuttling system for shuttling the print head (11) of a dot matrix line printer is disclosed. The print head (11) is supported by a pair of flexures (13, 15) such that the head is free to move back and forth along a print line. One end of the flexure supported print head is attached to the coil (31) of a voice coil linear motor (23). The linear motor (23) is also flexure (27, 29) supported. The linear motor (23) is positioned such that the axis of coil movement is co-axial with the axis of movement of the print head (11). Further, the resonant vibration frequency of the combination of the linear motor and the linear motor flexure support is tuned to the resonant vibration frequency of the combination of the print head and the print head flexure support. A position sensor (51), preferably in the form of a pair of windows (W1, W2) connected to the print head (11) to move therewith and control the light impinging on a pair of differentially connected photovoltaic cells (A, B), produces a signal denoting the actual position of the print head. The actual position signal is compared with a commanded position signal in a control loop and the resultant error signal is used to control the magnitude and polarity of the current applied to the coil of the linear motor and, thus, the position of the print head. The signals produced by the photovoltaic cells (A, B) are also used to control the intensity of the light impinging on the cells so that the sum of the photovoltaic cell signals is a constant.

Abstract: ABSTRACT       The invention provides a two-channel liquid crystal light valve image projection system with prepolarization using an oil coupled optical arrangement.  A prepolarizing beamsplitter is mounted in the container in optical align-ment with a first surface for splitting and prepolarizing light from a source into first and second beams having first and second polarization states, respectively.  First and second dichroic separators are mounted within the container for extracting light of a first color from the first beam and light of a second color from the second beam, respectively.  The separator outputs are recombined by the prepolarizing prism into a single beam which is directed to a second polarizing beamsplitter mounted within the container.  The second beamsplitter splits the single beam and directs light of the first and second polarizations through the second and third apertures, respectively.  Liquid crystal light valves mounted at the second and third apertures modulate the polarization state of the exiting light and return it to the second beamsplitter to be directed through the output aperture to projection optics for display.
