Abstract: A survey monument has a simple spring clip extraction restricting means formed as a wire form spring member to provide a straight leg inserted in a diametral opening in the rod and a curved co-planar leg which effects a snap fit with the outer periphery of the rod. An axially extending leg is offset radially outwardly and yields to displacement while imparting rotational torque to the rod when the rod is driven into the ground, but opens and restricts extraction when the rod is moved in an opposite direction.

Abstract: A method and device for filleting fish using an adjustable cutting blade, having a cutting edge mounted between first and second parallel legs which are rigidly connected by a base portion, opposed to the cutting blade. The length and curvature of the blade may be adjusted to conform to the thickness and roundness of the fish to be filleted.

Abstract: An apparatus and method is provided for the placement of a heat-shrinkable film over the open portion of a container such as a glass, paper or plastic cup. The apparatus is particularly suitable for rapid placement of a heat-shrinkable film on food and beverage containers such as are commonly used in the fast-food service business. The apparatus comprises a film transport subsystem for withdrawing heat shrinkable film from a supply roll, cutting the film to size and positioning it for shrinkage onto a container and a heating subsystem which shrinks the film onto the top of a container. Operation of the apparatus is initiated by manual placement of the top of a container to be covered, against the film, pushing the container and film upwardly into the apparatus. The upward movement of the container engages the film and container top with a bonnet which initiates blowing of hot air of heat shrinkable temperatures to heat the exposed edges of the film and shrink the film onto the container.
