A system that can accurately monitor and control low concentrations of ethylene gas includes a test chamber configured to receive sample gas potentially containing an ethylene concentration and ozone, a detector configured to receive light produced during a reaction between the ethylene and ozone and to produce signals related thereto, and a computer connected to the detector to process the signals to determine therefrom a value of the concentration of ethylene in the sample gas. The supply for the system can include a four way valve configured to receive pressurized gas at one input and a test chamber. A piston is journaled in the test chamber with a drive end disposed in a drive chamber and a reaction end defining with walls of the test chamber a variable volume reaction chamber. The drive end of the piston is pneumatically connected to two ports of the four way valve to provide motive force to the piston. A manifold is connected to the variable volume reaction chamber, and is configured to receive sample gasses from at least one of a plurality of ports connectable to degreening rooms and to supply the sample gas to the reactive chamber for reaction with ozone. The apparatus can be used to monitor and control the ethylene concentration in multiple degreening rooms.

Ethylene monitoring and control system

A fluid power operated fish skinning machine that severs the tail and impales the fish on a wheel. The fish is then rotated past cutting stations where the dorsal fins are removed and the belly flap is cut. The wheel is then stopped opposite a cutting wheel mounted on a drum which is rotatable about its axis in either direction and is pivotable against or away from the fish body. The drum is pivoted against the fish and a transverse slit is made by the cutting wheel in the fish across the backbone near the head of the fish. The drum is then rotated until a gripping device on the drum is disposed in the slit. The gripping device is then pivoted against the drum and grips the skin against the outer surface of the drum. The drum and wheel are then rotated in opposite directions about their axes such that the skin is peeled from the fish.
