Abstract: It consists of a disposable, single-use blank (1) made from a leaktight, flexible and thin synthetic material. This blank (1) has, when viewed flat and from above, the general shape of a diabolo whose upper and lower edges 2 are extended by strips 3 intended to overlap one another at least partially. Those portions of these strips 3 which enter into contact with each other have self-adhesive characteristics which enable them to be stuck together simply by means of pressure.

Title: Sealing bar for centrifugal grinders
Inventor: WILDEY ALLAN J
IPC: D21B1/18
Filed: 1987-06-04
Granted: 1991-07-02
Abstract: Abstract of the Disclosure A centrifugal grinder for pulp wood and wood chips has a stationary internal grinding surface and a rotor rotating within the surface.  The rotor has an axial feed passage for stock to be ground, and at least one passageway extending from the passage to the grinding surface.  A guideway in the rotor is disposed at an angle to the grinding surface and is located such that, as the rotor rotates, the guideway sweeps over the portion of the grinding surface in contact with the stock to be ground.  A sealing bar is located in the guideway, the bar being of a material softer than the grinding surface so that it can be worn down into conformity with the surface. A rack within the guideway is connected to the sealing bar, and a pinion engages the rack.  The rotational position of the pinion can be incrementally adjusted to advance the sealing bar toward the grinding surface, and the play between the rack and the pinion is sufficient to allow the sealing bar to be worn into substantial conformity with the grinding surface after the surface has been sharpened.

Title: Apparatus and method for thickening pulp and paper stock
Inventor: SEIFERT PETER
IPC: B04B3/00
Filed: 1987-07-02
Granted: 1992-06-30
Abstract: Abstract of the Disclosure Apparatus for thickening a suspension of pulp material, such particularly as paper making pulp in water, employs a single pair of rolls and a single loop of wire trained around both rolls which are spaced from each other on substantially parallel axes to provide two runs of the wire therebetween.  The pulp stock to be thickened is delivered into the wedge zone defined by the wire run approaching one roll and the surface of that roll, so that the pulp is trapped between the wire and roll as it travels around the roll with the wire, and the rolls are driven at sufficient speed to develop centrifugal forces which cause liquid to be expressed through the wire from the pulp trapped against the roll.  The resulting partially dewatered pulp is redeposited from the first roll onto the other wire run for travel to the other roll, where it is similarly subjected to centrifugal force for further expression of liquid through the wire, after which the pulp is removed from the surface of the second roll in the wedge zone defined by the surface of that roll and the wire run traveling therefrom to the first roll.

Title: Lithographic technique using laser for fabrication of electronic components and the like
Inventor: DAS SHYAM C
IPC: G03F7/004
Filed: 1987-08-07
Granted: 1991-01-15
Abstract: ABSTRACT OF THE DISCLOSURE      A microlithographic process of fabricating electronic components, such as, for example, integrated circuit chips and thin film read/write heads for computer disk systems, in which a laser is used to etch features defined by a mask.          The laser is selected whose radiation will be absorbed by the workpiece being etched, and the masking material is selected so as to be highly reflective of the laser radia-tion.  The masking material is patterned in a conventional manner so as to expose the portions of the workpiece material to be etched.  When the laser is directed to the workpiece, the laser radiation etches the portions of the workpiece not protected by the mask.    The depth of the recess formed by the laser can be limited by depositing an etch stop layer of reflective material on a substrate, followed by an intermediate layer of workpiece material to be etched, and then the reflective mask.  The laser radiation etches the intermediate layer through the mask to the etch stop layer, which prevents radiation from etching the workpiece further.    Depending on the material being etched, the etch may be improved if performed under a liquid transparent to the laser radiation.  The liquid may carry away the products produced by the etch.

Granted: 1994-02-15
Abstract: ABSTRACT           The force-locking connection between a shaft and driving elements attached to it is improved or achieved via a slight plastic expansion of the shaft in that the driving elements are arranged in groups and connected by connecting sleeves produced so as to be integral with the driving elements.  The higher degree of elastic expansion is limited to the region of the connecting sleeves so that the driving elements themselves are largely excluded from this process.  The dimensional accuracy of the finish-machined driving elements is not adversely affected.  If necessary, recesses may be produced to form webs as a result of which the elastic deformation occurring in the inner region is reduced.

Abstract: The cold-adapted  (ca)  temperature-sensitive  (ts) vaccine is prepared by serially passaging a suitably selected virus (e.g. Arkansas-type DPI strain) through a culture medium at a suboptimal replication temperature which  is  less  than about  35°C,  e.g.  28°C,  and harvesting the live, cold-adapted mutant for formulation into dosage units of,  for example, about 10 3 to about 10 5 EID50 /bird.   The ca ts mutant is much less able  to  replicate  at  40-42°C  (internal  avian  body temperatures)  than at  the  temperature of  the bird's upper  respiratory  tract,  which  is below  40°C.

Abstract: ABSTRACT:     A security enclosure is formed from layers of flexible material.  One layer carries a flexible semiconductive line arranged to extend over the whole area of the enclosure.  Any interruption of the line by unauthorized opening of the enclosure changes the resistance of the line and so can be detected by a monitoring circuit.  Further, two layers of semiconductive fibers also cover the whole area of the enclosure and are separated by an insulating layer.  The length of the fibers is greater than the thickness of the insulating layer so that if the enclosure is pierced fibers from one layer will be forced into contact with fibers from the other layer.  This will change the combined resistance of the layers and this can also be detected by a monitoring circuit.  The two measures can be used separately.
