The manipulator assembly comprises, a boom which has first and second end effectors each adapted to releasably secured to any one of the fixtures. First and second articulators are provided which serve to mount the first and second end effectors at first and second ends of the boom respectively. The first and second articulators provide a sufficient degree of movement between the end effectors and the boom to allow one end effector to be moved toward and away from one of said fixtures while the other end effector remains mounted on one of said fixtures. A power transmission system is associated with each articulator for articulating the boom with respect to either end effector whereby the manipulator assembly may relocate itself by sequentially securing and releasing one of the end effectors and then the other with respect to said fixtures.

Abstract: A de-boning machine comprises a pair of dies which are adapted to close around a meat portion in which a bone is located such that the meat is displaced laterally from the bone in response to closing of the dies while the bone remains in tact. The dies preferably have opposite disposed de-boning faces in which a bone locating recess is formed. To reduce the likelihood of damage to the bone resulting from closing of the dies, the bone receiving recess is filled with a resiliently deformable material such as a food grade rubber. In order to separate the meat which has been laterally displaced from the bone, a cutter is provided laterally outwardly from the bone receiving recess, the cutter being operable upon final closing of the dies.

Abstract: A meat support for supporting sausage in a smokehouse has a rotor mounted for rotation upon a support vehicle. The rotor has a plurality of horizontally extending pockets formed therein, each of which is proportioned to receive and support a sausage with its longitudinal axis horizontally oriented. The rotor is driven about its longitudinal axis such that the sausages which are located in the pockets of the rotor are caused to rotate about their own longitudinal axis. This rotation of the sausages when horizontally oriented serves to reduce moisture losses and to maintain a uniform moisture distribution throughout the sausage while it is cooked.

Abstract: In a gaseous fuel carburetion system in which air and gaseous fuel are mixed in a mixer prior to induction into an internal combustion engine, and in which the rate of flow of the induction air is controlled by throttling the intake of the air/fuel mixture, and in which gaseous fuel is supplied to the system from a pressurized source, an improved method and apparatus for regulating the supply of gaseous fuel to the air/fuel mixer is provided. The method comprises the steps of; sensing at least one operating parameter of the engine which is a function of the induction air flow rate and generating a control signal which varies in response to changes in the induction air flow rate, controlling the rate of flow of the gaseous fuel from the source to the mixer by means of said control signal whereby the rate of flow of the gaseous fuel varies in response to the sensed changes in the parameters related to the air flow rate.
