Abstract: A method of preservation and presentation including the steps of positioning a perishable product having a significant porosity and permeability into a gas impermeable package in the presence of a first agent, thereafter sealing the product in the package in the presence of the agent under a positive pressure and maintaining gas communication between the product and the first agent for a time necessary for the concentration of the first agent to be reduced by 50%.

Abstract: An adjustable sawhorse for contemporaneously adjusting both the height and angle of inclination of the support member. The sawhorse utilizes a disk-jaw slip clutch composed of a shaft carrying a pair of inner and outer disks in slideable and rotational relationship. The shaft extends through a transverse cavity in the support member and the support member is interposed intermediately of the disks. A plurality of radially extending jaws extend from the transverse cavity openings in the support member sidewall surfaces for engagement with corresponding radially extending jaws on the inner disks' engagement surface with the support member. Similarly, the outer disks have radially extending jaws which couple with like constructed jaws on the engagement faces of the outer disks. By exertion of a lateral compressive force, the disks and support member may be releasably locked in fixed rotational relationship.

Abstract: This invention relates to a Wharf fender assembly for use with wharves or docks made generally from resiliently deformable material.The Wharf Fender assembly includes an elongate tubular bender body attachable to adjacent wharf which is generally progressively increasing width or transverse dimensions from one end to the other end thereby providing a larger end and a smaller end. There is also included buffer means operatively associated with the fender body which may withstand an impact from a ship or other vessel when the fender body is attached to the wharf. The invention also includes within its scope a fender body per se.
