Abstract: With the device and method, ground meat is pumped through an elongated discharge tube into a plastic bag at the bottom of a frustoconical-shaped mold casing. The mold casing cooperates with a pneumatic or air inflatable elastic resilient piston that causes the meat being pumped through the discharge tube to be packed tightly down to a desired texture. As more meat is pumped into the bag and mold casing, the piston when inflated has a varying diameter and the mold casing moves axially downward with respect to the resilient piston to allow for more room for meat in the mold casing and bag until a point is reached where the discharge tube along with the inflated piston are forced out of the mold casing by downward movement of the mold casing.

Abstract: The invention concerns an apparatus which can be utilized for the quality inspection of fish fillets and enables the detection of faulty spots resulting from processing deficiencies, such as skin or fin remainders, blood spots, bones, as well as from parasites and others. To this end, fillets are guided to a light emitter by means of a conveyor belt which is made from a material which allows light to pass at low absorption. The light emitter comprises light sources which are arranged out of direct sight by means of screens. Due to its characteristic to allow light to pass by dispersion, the fillet will appear illuminated in darker surroundings.

The relative dimensions of the ball and cavity are such that the ball is constrained against rattling against the walls of the cavity with movement of the lure and instead is guided to follow a rolling movement around the walls of the cavity, producing a sound frequency attractive to fish. The chamber is provided in a suitable lightweight plastics material capsule embedded in the lure body, and may be of circular dome or annular shape.

Abstract: An animal trap suited for trapping rodents comprising an elongated container having a curved bottom surface and a vertically translatable gate for selectively enclosing an opening in one end of the container after the animal has entered the trap. When set, the trap rests on one end of the bottom surface by gravity with the gate held elevated from the container to permit an animal to enter the trap. When the animal travels toward the opposite end of the container toward the bait remote from the opening, the weight of the animal causes the container to rotate elevating the open end of the container, releasing the gate thereby closing the opening to the container and trapping the animal therein. The gate remains closed by gravity acting downward thereon.
