Filed:

Jun 2, 1994

Appl. No.:

8/252722

Inventors:

William M. Lester - Livingston NJ

International Classification:

B65D 5502

US Classification:

215230

Abstract:

Tamper indicating closure device for securely sealing a container in the form of a clear cap and indicator element. The cap includes knife blades in the form of ramp shaped projections which extend from the bottom side of the cap surface. Each knife blade is radially offset from the center of the cap and extends generally parallel to the radius of the cap terminating in a generally vertical planner knife face that extends in an axial direction. A tamper indicating element including a first covering layer and a second color layer is inserted into the cap prior to securing the cap and indicating element to a container. When the cap is screwed onto the container, the ramp like shape of the knife blades cause the knife blades to pass over the indicating element without tearing or piercing. When the cap is removed from a secured relationship with the container, the generally vertical knife face tears the cover layer of the indicating element exposing the color layer and thereby providing an indication of tampering. Because the knife blades do not pierce the indicating element during assembly, a sealing layer may be used to protect the contents of a container from the atmosphere without the need to flatten knife blades or apply sealant thereto to avoid the possible piercing of the sealing layer during assembly.

E02D 2734

US Classification:

521671

Abstract:

An free standing platform for enabling elevated structures to survive earthquakes in which the columns supporting the elevated structure rest and float on platforms positioned between the columns and the ground, said platforms able to withstand and dissipate the forces present during an earthquake, and said columns being able to slidably move atop said platforms, thereby enabling the columns to survive the earthquake intact and to continue supporting the elevated structure.

Abstract:

Horizontally movable mold halves respectively journal different plungers for movement within coaxial bores extending through the closed mold halves. With the mold closed, and one plunger extending through the mold to one side, a metered compartment is formed between the two carefully positioned plungers. A charge of molten metal, or the like, is transferred from a reservoir into the compartment and moved into the mold cavity by moving the two plungers in unison to a position at the die surface of the respective mold halves. After hardening, the mold halves are separated and one plunger ejects the molded article from the mold. The plungers and mold halves are moved by hydraulic cylinder rams into a sequence of fixed positions for different steps of a programmable molding cycle. Sensing switches provide feedback for establishing the plunger positions at various cycle steps. In particular a variable movable sensing switch establishes the capacity of the molten metal metered compartment to produce a charge precisely tailored for the mold cavity.

International Classification:

US Classification:

222495

Abstract:

A housing containing annular tapered valve seat and mating valve secure the valve in fluid communication with the container interior. Fluid in the container under pressure displaces the valve from its seat, flows through the interface between the valve and seat and is discharged to the ambient through a fluid passage coupled to the interface. A shoulder in the housing engages a shoulder on the valve for limiting the displacement of the valve to a value sufficiently small to retain fluid in the interface in the absence of pressure above ambient in the container. The fluid in the interface acts effectively as a seal to ambient air so that a negative pressure in the container results in ambient air pressure forcing the valve to its closed position.

International Classification:

F02B 5308

US Classification:

123 841

Abstract:

This engine or energy converter has a casing comprising coaxial spaced sections each having a cavity bounded by opposed parallel flat inner side surfaces merging with semi-cylindrical top and bottom inner surfaces and a rotor coaxial with said sections, having rotor portions in said sections. Said rotor portions carry outwardly spring pressed opposed aligned radial pistons. The pistons of one rotor portion are disposed at right angles to the pistons of the other rotor portion. In each section there is formed a top chamber on one side of the rotor portion for said sections and a bottom chamber on opposite side of the rotor portion for said section. Means is provided to feed combustion gases to the top chambers of said sections in timed relation, to compress said gases in said top chambers, to form explosive charges, transfer the charges from the top chamber of each section to the bottom chamber of the other section, to fire the charges in the bottom chambers in timed relation to explode the charges, and to exhaust the combustion gases in timed relation.

US Classification:

123 843

Abstract:

This engine has coextensive rotors on parallel axes in coextensive cavities having parallel axes. In each cavity there is an inlet and compression chamber on one side of the rotor in said cavity and an explosion and exhaust chamber on the other side of said rotor in said cavity. The engine also has valve means to allow compressed combustion gas from the inlet and compression chamber of one cavity to pass to the explosion and exhaust chamber of the other cavity. Each rotor carries diametrically disposed, outwardly spring pressed radial pistons to sweep through said chambers in wiping relation to the internal surfaces of said cavities. The rotors are connected for rotation in the same direction at equal speeds.

International Classification:

B67D 300

US Classification:

222153

Abstract:

A housing is threaded to the container and includes a valve stem having a flexible valve disc member. In the housing are upper and lower adjacent valve seats which mate with the disc member to form closed valves therewith. When in contact with the upper seat the valve can be opened and closed by the pressure differential between the container and the ambient. When manually placed in contact with the lower seat the disc member snaps in place by flexing over the upper seat into a locked closed valve state with the lower seat and does not open in response to pressure differentials between the container and the ambient.

Abstract:

An eyeglass frame made as one integral piece from a molded flexible, resilient synthetic material such as a polypropylene plastic which is able to return to its original shape when deformed, wherein said eyeglass frame includes a housing for lenses, and further includes temples which are able to be moved back and forth through 180. degree. in relation to the housing by means of a series of resilient deformations situated at specified spots along the molded material, thereby eliminating the need for screws and/or bolts to couple the temples.
