Abstract: METHOD AND APPARATUS FOR CONTROLLING        TENSION IN A STRAP LOOP              ABSTRACT OF THE DISCLOSURE         A method and apparatus is provided for tensioning a strap loop about an object and terminating the tensioning of the strap loop at a predetermined loop tension.  The object is encircled with a loop of strap having a predetermined thickness, width, and coefficient of friction.  A leading end portion of the strap is restrained while disposing a trailing portion of the strap adjacent a traction wheel that is rotatable about a first axis at a predetermined maximum available torque.  A pressing member that is pivotable about a second axis oriented parallel to the first axis and that has a predetermined configuration and coefficient of friction is biased toward the traction wheel to press the strap trailing portion against the traction wheel. The traction wheel is rotated about the first axis to grip the strap and slide the strap along the pressing member for tensioning the strap loop while permitting the sliding friction force imposed on the pressing member to pivot the pressing member further toward the fraction wheel to further compress the strap between the traction wheel and pressing member to increase the sliding friction resistance force on the strap and overcome the tangential force imposed upon the strap by the traction wheel at the maximum available torque to terminate the traction wheel rotation at the predetermined loop tension.

Abstract: Docket BKS 177 P2 Abstract of the Disclosure A cutter for comminuting a moving continuous sheet or web, such as paper broke, in the dryer or converter section of a papermaking machine, includes a plurality of high pressure water jet cutting nozzles positioned in a conduit section for receiving such broke from the papermaking machine.  In one embodiment the nozzles are arranged in banks positioned to impact the sheet as it passes through the conduit section, from opposite sides, and are mounted on water conduits which, in turn, are mounted for reciprocating movement and are oscillated transversely of the direction of sheet movement by a mechanical drive. The cutting jets from the high pressure nozzles impact the sheet simultaneously at opposite sides, while being reciprocated to reduce the sheet into a multiplicity of smaller discrete or easily separable pieces which fall through the bottom of the conduit section, for further processing or disposal.  The nozzles may be directed at an angle to the direction of sheet movement, so as to impart a force component tending to pull the sheet through the conduit section.          In another embodiment, an open face roll forms a backing support for the sheet and a mutually reciprocating pair of nozzle banks have cutting jet sprays directed against and through the sheet supported on the open face roll.

Title: An apparatus and method for forming slits
Inventor: AIHARA KINTARO
IPC: B26F1/20
Filed: 1991-05-01
Abstract: A slit forming apparatus consists essentially of a rotary blade assembly, a rotary backing roller, and pressing projections.  The rotary blade assembly contacts with or abuts against a strip-shaped travelling over the rotary backing roller and then penetrates said material to form slits in it.  The backing roller has banks for holding the strip-shaped material pressed by the rotary blade assembly, and also has grooves for receiving the blades of the rotary blade assembly when they penetrate the strip-shaped material.  The pressing projections provided at opposite side ends of the assembly prevent the undersired movement of said material in the lateral or longitudinal direction.  With this apparatus, substantially defect-free satisfactory slits are formed in the strip-shaped material.

Title: Recombinant negative strand rna virus expression systems and vaccines
Inventor: PALESE PETER
IPC: C12N15/11
Filed: 1990-08-27
Abstract: Recombinant negative strand virus RNA templates which may be used to express heterologous gene products and/or to construct chimeric viruses are described.      Influenza viral polymerase, which was prepared depleted of viral RNA, was used to copy small RNA templates prepared from plasmid-encoded sequences. Template constructions containing only the 3' end of genomic RNA were shown to be efficiently copied, indicative that the promoter lay solely within the 15 nucleotide 3' terminus. Sequences not specific for the influenza viral termini were not copied, and, surprisingly, RNAS containing termini identical to those from plus sense cRNA were copied at low levels. The specificity for recognition of the virus-sense promoter was further defined by site-specific mutagenesis. It was also found that increased levels of viral protein were required in order to catalyze both the cap-endonuclease primed and primer-free RNA synthesis from these model templates as well as from genomic length RNAs. This indicated that this reconstituted system has catalytic properties very similar to those of native viral RNPs. High levels of expression of a heterologous gene was obtained using the constructs and methods described.

Title: Dc/dc power transformer
Inventor: LALANDER MAGNUS
IPC: H02M3/315
Filed: 1990-11-02
Abstract: The DC/DC power transformer is an arrangement for direct transformation of high electric powers from one DC voltage level to another DC voltage level without intermediate AC voltage network. The DC voltage is today basically used for transmission of high electric powers at long distances.  The DC voltage levels for these transmission are normally high. The DC/DC power transformer allows several DC voltage levels to be used in one and the same DC voltage network. The principle for this arrangement is that the valve windings (43, 45) from one or several converter transformers (47) are connected to two valve bridges, which generate opposing cyclically variating magnetic flows in the transformer cores (44). One of the valve bridges is operated as an inverter (49) and the other as a rectifier (46) and in this manner the power is transformed from one DC voltage level (Ud1) to another (Ud2). At the high voltage levels for which the invention is intended the leakage inductances in the transformers will be high as a consequence of the insulation levels and due to this special arrangements must be made in order to commutate the magnetic energy from one phase of the transformer to another without creating great losses. The arrangement is proposed in a line commutated alternative (figure 5) and in a selfcommutated alternative (figure 4). The first utilizes a third AC voltage reference winding (A3, B3, C3 in figure 5) for this commutation.  In the second alternative an external over the bridge connected capacitor (48 in figure 4) is utilized for this commutation purpose. Both alternatives may be designed galvanically insulated or in autocoupling (figure 10).

Abstract: ABSTRACT OF THE INVENTION         The delivery system of the invention overcomes the above-noted shortcomings and consists of at least two stainless steel, rigid syrup storage tanks  The tanks axe connected to a carbonated beverage mixer and dispenser via a automatic vacuum selector valve.  The valve operates to change over between tanks when the tank providing syrup becomes empty and a vacuum is created in the supply line to the selector valve.  The vacuum is created in the supply line by an automatically operating valve that closes the supply line when the tank is empty.  A cleaning system is also provided that can be connected to the vent of the empty tank to clean it before it is refilled with syrup.  A drain line cooperates with the valve to maintain the valve in its open position and allow the cleaning fluid to drain from the tank.
