Abstract: A nuclear magnetic resonance gyroscope is disclosed that operates on the principle of sensing angular rotation rate as a shift in the Larmor frequency of one or more nuclear species that possess nuclear magnetic moments.

Abstract: Apparatus for supporting humans in a vertical head-down position, including apparatus for climbing into position.

Abstract: A method for fabricating multiple layer interference optical films by ion beam sputtering, said films being used for mirrors in a ring laser apparatus. An ion beam strikes a target material obliquely, dislodging molecules of the target so that they can be deposited on a surface serving as a base for a multiple layer interference coating. The thickness of the coating is monitored so that the proper thickness of a given layer can be optimized to obtain the type of reflectance desired for a given light wave length. The surface to be coated is rotated during the deposition of the layer of target material. A stack of layers of alternating indices of refraction comprises the optical interference film. The coating process occurs inside of a vacuum chamber where the partial pressures of the gases are carefully controlled to insure the proper ion beam intensity and optimum stoichiometry of the deposited optical films.

Abstract: Apparatus for delivering metered amounts of varnish to the surface of a metal can, or the like. Varnish is delivered to a metering roll having recesses in its surface and a doctor blade to scrape off excessage. The varnish in the recesses of the metering roll is delivered to a varnishing roll in continuously metered amounts, and it is delivered by the varnishing roll to the surface of a can, or the like. Remaining varnish is removed from the varnishing roll by a second doctor blade so that substantially no varnish is present on the varnishing roll at the points of delivery of metered varnish to such varnishing roll.

Abstract: A closure configuration for the top of a carton wherein the underneath flaps of the closure are scored to facilitate sealing.

Abstract: A round tray and a blank for making the tray. The tray has a bottom panel, a plurality of intermediate panels symetrically disposed about the center of the bottom panel, and a plurality of upstanding panels to form the sides of the tray. The upstanding panels may be tilted slightly outward in a conical shape to cause the diameter of the top of the tray to be slightly larger than the diameter of the bottom of the tray. Alternate ones of the upstanding panels are positioned on the inside of the tray, and their adjacent upstanding panels have circumferentially extending glue flaps which overlap the inner panels. The total number of upstanding panels and the total number of intermediate panels are equal, with each upstanding panel being foldable relative to an intermediate panel immediately below it about a first set of fold or score lines. The intermediate panels, in turn, are folded upward from the horizontal about a second set of fold or score lines.

Abstract: A belted-track vehicle, unpowered and attached to a cantilevered apparatus to support the apparatus clear of the ground and adapted to be driven by the apparatus.

Abstract: A new score line configuration having easy opening characteristics for opening an ice cream carton and the like, has the characteristic of avoiding premature separation particularly during set up of the carton.

Abstract: A carton particularly adapted for ice cream including a front wall, bottom wall, rear wall, top cover panel, front cover panel, corner glue tabs, cover end skirt panels, rearward and front inner end wall panels, and a pair of end walls, wherein, said end walls have a weakness line separating their outer margins from the lower panels thereof and said cover end skirt panels are glued to said outer margins to break said outer margins away from the lower panels of said end walls when the erected box is opened.

Abstract: A carton, adapted for use in heating a product, is provided with openings to permit gas and heat flow. An integrally formed section of an outer panel of the carton serves to cover the openings, and is readily removed prior to use of the carton. As an additional feature, the panel in which the removable section is formed may also provide elements which can be positioned to function as legs to elevate the carton above a supporting surface.

Abstract: One or more finger puppets positioned in the wall of a preferably transparent enclosure. The enclosure is partly filled with particles of material to selectively hide the finger puppets.

Abstract: An easy-opening container having a pouring spout within the container, adapted to be pulled outward by a pull member, the pouring spout being characterized by outwardly extending flanges having holes therein, the flanges contacting the inside of the container adjacent the pouring spout to seal between the spout edges and the container when the spout is fully extended.

Abstract: A threaded material dispenser having first and second substantially identical contoured members, hinged together to fold into overlapping position with said second member supported by said first member; each member preferably being pliable and having a depressed central region surrounded on at least three sides by raised portions, so that at least one skein of yarn positioned between said members in the central region thereof may be dispensed between said raised portion of said two members without pulling out the skein of yarn, said raised portions and the walls of one of said central regions preferably enclosing granulated material.
