Patent number: 4876896Abstract: The method and apparatus for forming an encapsulation or encasement about a structural member that is particularly well suited for use in a marine environment is disclosed. A two component polymer system for protective and repair encapsulation is pumpable in two separate streams to the location of the structural member to be encapsulated. The two reactive components are combined in a static mixer immediately prior to being injected within the surrounding translucent jacket. By combining the reactive components immediately prior to use, premature set up is avoided and the resulting grout may be directed to flow upwardly in the jacket for enhancing final properties. By suitable coloring of the components, visual monitoring of the final mixing and distribution in the translucent form or jacket of the encapsulation material may be monitored. A field test for determining bond strength of the encapsulation polymer to the structural member is also disclosed.Type: GrantFiled: June 16, 1986Date of Patent: October 31, 1989Assignee: I.W. Industries, Inc.Inventors: Richard K. Snow, Milton W. Ellisor, Jr.

Patent number: 4728361Abstract: Magnesium bullets are shot into molten Ferrous alloys in a ladle to react with oxygen and sulfur to form magnesium gas and slag. Boron and ferro-boron bullets are also employed with magnesium bullets. The resulting iron alloys have superior physical properties. The machine which discharges the bullets into the ladle includes a first solenoid actuated gate supporting the lowermost bullet in a column of additive bullets received in a tubular upright magazine of an air gun so as to release the bullets by gravity, one at a time, into the chamber of the air gun.The air gun is disposed over a container of molten metal. A second solenoid actuated gate releasably supports the bullet in the chamber and a solenoid actuated valve in a compressed air line releases the air to drive the bullet down through the barrel of the gun and into molten metal. The angle of the counce can be varied. The arrangement is particularly useful for introducing magnesium into white iron and introducing boron into gray steel.Type: GrantFiled: October 23, 1986Date of Patent: March 1, 1988Assignee: G. I.

Patent number: 4492488Abstract: A substantially tubular housing houses a swivel unit proximate one of its ends and a tailpiece proximate the other of its ends; with a relatively strong spring disposed therebetween to urge each unit against its respective housing end with sufficient pressure to retain each such unit as selectively positioned. A swivel seat washer is disposed between the spring and swivel; while a pair of washers, one plastic and one brass, are disposed between the spring and tailpiece. The swivel unit includes an extension with external threads and flat sides that cooperate with flat sides of an opening in the housing end and through part of the sidewall of the housing; the flat sides of the extension and of the housing opening coacting to restrict rotation of the swivel to ninety degrees of rotation about a first axis of rotation.Type: GrantFiled: October 15, 1982Date of Patent: January 8, 1985Assignee: I.

Patent number: 4381538Abstract: A lamp swivel composed of two main coaxial members, which are at least partially rotatable relative to each other. An inner pin extends from one member to a circular inner groove in the other member, the groove being coaxial with the members. However, the other member, usually composed of a metal such as brass, copper or aluminum which may be anodized, is coined so as to prevent egress of the pin from the groove. Thus the two members are semi-permanently attached to each other and can rotate, by less than 360 degrees, relative to each other. The invention is especially applicable to provide an articulated lamp mounting for a swing arm lamp or the like, the lamp swivel being a swivel connector or coupling means which provides an articulated mounting attachment for the lamp.Type: GrantFiled: October 13, 1981Date of Patent: April 26, 1983Assignee: I. W. Industries, Inc.Inventor: Jerome Warshawsky

Patent number: 4322098Abstract: A swivel assembly comprises a housing having a bore extending therethrough along a central axis. The housing has an end wall with an opening about the axis extending therethrough. A generally spherical swivel member is rotatably and swivelly disposed in the bore and includes an extension protruding through the opening. The portion of the extension within the opening is substantially smaller in transverse cross-section than the opening to permit limited swivel movement of the swivel member in the housing. The bore has first and second sections. The first section has a smaller diameter than the second section and thereby forms a wall. A stiff resilient element is provided between the wall and the swivel member for preventing movement of the spherical swivel member when subjected to a heavy load.Type: GrantFiled: October 31, 1980Date of Patent: March 30, 1982Assignee: I.
