Title: Process and apparatus for the preparation of  flat-fish for the bleeding
Inventor: GOTZ KLAUS
IPC: A22C25/00
Filed: 1980-02-01
Granted: 1982-05-11
Abstract: ABSTRACT OF THE DISCLOSURE:     A process and an apparatus for mechanical opening of the bloodstream of flat-fish, the application of which has the aim of the bleeding of the fish.  The apparatus proposed for this is equipped with a rotatingly driven knife sleeve, which is sharpened at its end side and which is constructed to be lowerable onto the flat-fish aligned to be lying flat under this, and at its circumference carries tearing elements extending radially in the proximity of the cutting edge.  The tool, penetrating into the abdominal cavity during lowering while separating circular area portions out of the oppositely disposed abdominal walls, tears the bloodstream disposed at the underside of the spinal column open by means of the radial tearing elements.  Through a radially deviatable arrangement of the latter, there results an adaptation of the tool to the geometric conditions of the abdominal cavity as well as an enlarged radius of action through the ratation in conse-quence of centrifugal forces, which effects the tearing loose and comminution of the intestines.  The feeding of rinsing liquid through the center of the tool into the abdominal cavity makes the flushing-out of belly contents possible.

Abstract: Abstract A projection lens is mounted between a movable stage and a stationary holder to project an image of a reticle held by the holder onto a semiconductive wafer held by a chuck mounted on the stage.  The stage is movable along orthogonal X and Y axes in a horizontal plane to align different regions of the semicon-ductive wafer with the projected image of the reticle.  First and second movable plane mirrors fixedly mounted on the stage for movement therewith are symmetrically disposed relative to the Y axis in first and second vertical planes intersecting one another at the Y axis.  Similarly, first and second stationary plane mirrors fixedly mounted on a housing of the projection lens are disposed parallel to the first and second movable mir-rors, respectively.  As the stage is moved along the X and Y axes, first and second interferometer systems provide first and second measurement signals indicative of the velocities of the first and second movable mirrors (relative to the first and second stationary mirrors) while they are being moved along first and second measurement paths normal to the first and second movable mirrors, respectively.  In response to the difference and the sum of these measurement signals, first and second position control circuits move the stage along precisely orthogonal X and Y axes with the Y axis bisecting the angle between the first and second movable mirrors.  Each of these position control circuits may be provided with a variable phase shifter responsive to a reference signal and a control signal for producing an output signal of the same frequency as the reference signal but shifted in phase as determined by the control signal, and with a phase detector respon-sive to the output signal from the variable phase shifter and to the first or second measurement signal for producing a position control signal proportional to the difference in phase between those signals.  The difference and the sum of the position con-trol signals of selected phase produced by the position control circuits are employed to extend the resolution of the position control circuits.

Title: Collagen net-like casing, extruder and process  therefor
Inventor: ZIOLKO FRANCIS J
IPC: A22C13/00
Filed: 1980-04-14
Granted: 1981-12-08
Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a smooth surfaced collagen casing having a tubular structure comprising two hardened con-centric layers united with one another.  Each of the layers possesses a plurality of collagen ropes oriented in a direction opposite to the ropes in the other of said layers.  The products of the invention, after suitable finishing treatments, are par-ticularly adapted to be utilized as an edible casing for fresh pork sausage which must be cooked before they are consumed, as well as sausages of the weiner or frankfurter type.  The latter type sausages are generally processed by being smoked and cooked by the packer and are generally merely reheated before they are consumed.  When sausages are provided with edible casings, it is unnecessary to remove the casing before the sausage is eaten.

Abstract: ABSTRACT OF DISCLOSURE This invention relates to a trench shoring assembly which includes a pair of spaced-apart side walls for vertical disposition within a trench. Spreader pipes and spreader collars interconnect the side walls and allow limited pivotal movement between the side walls.  Each side wall includes outer and inner metal plates connected to a horizontally extending hollow top beam which extends longitudinally along the top of the side wall, two intermediate beams parallel the hollow metal beam and a bottom beam.  A hardwood insert is disposed within the top beam to prevent the collapse of the hollow metal beam. A number of hollow beams extend perpendicularly to the horizontal beams and ribbed members extend perpendicularly to the horizontal beams.  The side walls of the assembly have a tapered bottom portion which defines a triangularly shaped pointed lower extremity extending between the ends of the bottom portion. A metallic bar is disposed at the pointed lower extremity and extends between the ends of the bottom portion and protects the bottom of the side wall against abrasion.  A U-shaped member is welded to the main frame, and, in turn, a spreader collar is welded to the U-shaped member so that a force applied to the spreader collar is transferred directly to the main frame.  Each spreader pipe spaces the side walls apart between two spreader collars to which the spreader pipe is attached by spreader pins.  Lifting rings are slidably attached to the spreader pipes for lifting the assembly.  A plurality of flanges extend from a spreader pipe and are connected by locking pins to mating flanges which extend from another spreader pipe of another vertically stacked trench shoring assembly.
