Title: Mechanical application of classification stamp to slaughtered carcass - where stamp and support are mounted on pistons to hold and stamp carcass legs automatically
IPC: A22C17/10
Filed: 1979-06-21
Abstract: Classification marks are applied to the hind legs of slaughtered animals, partic. pigs. by means of stamps mounted on a guide rail system which permits the stamps to move in a horizontal plane and supports which come into contact with the back of each leg as the stamp is applied. The stamps and supports are moved in a direction perpendicular to the guide rails pref. by means of hydraulic or pneumatic cylinders, the stamps and supports being mounted on the ends of the piston rods. The support is in the form of a fork to ensure that the leg is held securely during the stamping action. The pig is usually suspended by the front legs and opened out in two halves. In this case, the stamp and supports are arranged in pairs so that both legs of a single pig are stamped simultaneously. A dye pad, also actuated by a cylinder, swings over the stamp when it is withdrawn. The device eliminates the manual application of classification marks to the legs of the animal in the slaughter house.
Patent ES-8101826-A1 (ES)
Title: Method and apparatus for elaborating and processing two distinct pulse trains carrying information.
IPC: G06V30/224
Filed: 1979-10-29
Abstract: A system for generating and processing pulses representing information, from two pseudoperiodic analog signals along two interconnected channels. Each pseudoperiodic signal is generated by a separate magnetoresistor and is converted in an associated channel into two series of pulses. Conversion is effected by means of threshold switching circuits which control the operation of a bistable flip-flop via a combining circuit. The output of the bistable flip-flop in each channel is cross-connected to one input of a combining circuit in the other channel, the other input of which is a low threshold signal corresponding to the pseudoperiodic signal fed to that channel. The gate produces the logic product of its inputs which drives a flip-flop. The output of the flip-flop is terminated by a reset pulse derived from a zero reset stage.
