Abstract: The present invention relates to papermaking and particularly to a method of producing a fibrous web of uniform thickness and variable width which comprises feeding fibres from a supply zone which is in a fixed position and has a first lateral dimension into an expansion zone, permitting said fed fibres to fall through said expansion zone while moving laterally outwardly to form downwardly progressing zones of progressively decreasing fibre density, establishing a suction zone beneath said expansion zone said suction zone having a second lateral dimension which is variable and greater than said first lateral dimension and reducing the pressure in said suction zone to below the pressure in said expansion zone by an amount sufficient to form a web of fibres between said expansion and suction zones but insufficient to prevent said laterally outward movement of said fed fibres and forming a web of fibres between said expansion and suction zones which extends over the whole width of said second lateral dimension a

Abstract: A method of producing U.V. radiation by effecting an electrical discharge such that at least a part of the discharge path is submerged in water. An apparatus for performing the above method comprises two electrodes spaced apart to form a discharge region, a discharge chamber containing the discharge region, means arranged to apply a high voltage across the electrodes, and means arranged to supply water to the discharge region such that at least a part of the electrical discharge is submerged in the water, at least a portion of the discharge chamber being transparent to U.V. radiation. Also, a method of treating a material comprising producing U.V. radiation as described above in a discharge chamber at least a portion of which is U.V. transparent, passing the material through a treatment chamber adjacent the transparent portion of the discharge chamber; and an apparatus for performing the method of treating a material.

Abstract: An integrated facility for breaking dressed animal carcassas includes a continuous flow of the carcasses and their subdivisions through a series of processing areas where the carcasses are broken into primal cuts, the primal cuts are further divided, boned and trimmed along processing lines designated for particular primal cuts, the secondary cuts thus produced are then trimmed and boned as necessary, packaged and sorted according to their weight. Groups of the secondary cuts are placed in boxes which carry machine-readable markings which indicate the box contents. The filled receptacles are carried by a common conveyor to an area where they are sorted into groups according to the machine-readable markings, palletized by groups and placed on unidirectional refrigerated storage conveyors. Orders for products are filled by discharging the pallets from their respective storage conveyors, depalletizing the goods and routing the boxes to designated transport vehicles.

Abstract: An apparatus for the mechanical operation of thread or yarn guides in textile making machines. The apparatus includes selectors arranged longitudinally of the guides, and by means of pulses supplied from outside, the selectors are adapted, by form-closed engagement with the guides, to prevent and, in the absence of an engagement, to permit the guides being carried along by continuously reciprocating operating means. The apparatus also includes spring means which tend to move the guides out of such an engagement with the selectors as will prevent the guides being carried along by the operating means.

Abstract: An apparatus for leading off air from liquid, preferably blood, and for measuring the flow of liquid through the apparatus which comprises two chambers separated by a partition formed with a throughflow aperture. One chamber is movable in relation to the other chamber and adapted, in relation to the amount of liquid in one or the other chamber, to control a valve regulating the build-up of pressure in the apparatus.

Abstract: Method for hollowing out an article of food such as a fruit or vegetable so that a shell of substantially uniform predetermined thickness is formed. A rotating knife is rotated about its axis, while an end area of an article of food is guided with a curved guide member against the rotating knife. The guide member loosely supports the food for rotation and translation about its longitudinal axis while maintaining the knife a predetermined distance from the surface of the food. The distance between the guide and the blade is adjustable to control the thickness of the shell.
