Abstract: A method and apparatus for exercising the abdominal muscles where the exerciser is seated and the legs are spread apart and held in that position during the exercise which is accomplished by bending the upper torso forwardly and rearwardly through exertion of the abdominal muscles against a resistance offered by a weight stack. The machine includes a movement arm having a resistance pad engageable by the chest of the exerciser as the exerciser moves forwardly to perform positive work and rearwardly to perform negative work. The movement arm includes two parts one of which includes the resistance pad and is mounted to the other part by means of a spring mechanism so that the pad is spring mounted and may be moved to a raised position to allow easy entrance and exit from the machine. A cam fixed to the movement arm is connected to the weight stack pin by means of an actuating lever located below the weight stack.

Abstract: A machine for removing fish, in particular what is left on the bones after filleting, from the bones, in which the machine comprises two shafts (4, 4') which are movable relative to each other and on which there are wheels (9) with knurled surfaces which can draw a fish bone over scrapers (14, 14') which are provided for the purpose and which scrape over the side bones and against the main bone along the top and along the bottom and left and right of the main bone, and by means of which fish is obtained in the form of strips with the original structure.
Abstract: A meat deboning sieve (A) is disclosed which includes a plurality of sieve plates (10, 10') stacked together in a sieve assembly (15). Radial grooves (B) in the sieve plates are machined along a radial center line of the assembly to define radially aligned slots (D,D') in sieve (A) when stacked and compressed together in a unitized construction. A bonding agent (62) bonds mating surfaces (64) together to eliminate any voids and accumulation of bacteria. A hardness coating (48) reduces friction reducing the temperature of the meat product and energy consumed.
Abstract: An apparatus for separating a soft material such as meat from a hard material such as bone has a generally stationary support and a holder that supports an object comprised of the hard and soft materials stationarily adjacent the support with an interface between the hard and soft material extending to a cutting plane. A chassis is pivotal on the support about a chassis axis transverse to the plane and an outer pulley is pivotal on the chassis remote from the support and generally tangent to the plane. A carriage displaceable on the support transversely of the plane pivotally suports an inner pulley pivotal on the carriage close to the support and spaced along the plane from the outer pulley. One of the pulleys is rotated to advance the chain.
