Abstract: A spout for a gasoline nozzle providing vapor control for gasoline vapor produced during the filling of a vehicle tank. The spout includes a curved rigid tube having an inlet end for attachment to an outlet of a gasoline nozzle and an outlet end adapted to extend into the mouth of a fill tube of a vehicle tank. A rigid housing surrounds the tube and has a rearward end in sealing engagement about the tube, a forward end and a vapor outlet port. The housing defines, with the wall of the tube, a vapor receiving chamber therebetween. Vapor passages are located at the forward end of the housing which communicates with the chamber and the port as well as with the vehicle tank. The forward end of the housing is supported by a sleeve having a rearward end which extends into the forward end of the housing and a forward end that extends into the fill tube of the tank, the forward end of the sleeve having openings for the receipt of vapor from the tank which communicate with said passages.

Abstract: A foam filled die cast metal baseball and softball bat has an all metal skin welded into a unit. The bat is formed by die casting the cylindrical handle and barrel of the bat in one piece and by welding an end cap to the cylindrical barrel to form the unitary skin structure of the bat. A foaming, sound-deadening and strengthening plastic material is then introduced into the hollow interior of the bat through an opening in the handle portion of the bat. The added material foams to fill the interior with a reinforcing semi-rigid foam. The bat has a steel safety rod embedded in the foam center of the bat. The end cap structure is formed of a roughly hemispherical cap and has a sleeve which fits into the interior of the barrel end of the bat. A shoulder on the cap abuts the bat end and extends outwardly radially past the periphery of the bat. The cap is joined to the barrel portion by resistance welding in a rotating lathe under an inert gas atmosphere.

Abstract: A floating support defines an open area, and it removably holds a net adjacent that open area. That floating support holds the leading edge of that net below the surface of a circulating body of water in a swimming pool, but it holds the trailing edge of that net above that surface so objects which are floating on and moving with that body of water will move into and be held by that net. That net is light in weight, and it can be raised vertically from the floating support for emptying. Also, a floating barrier extends forwardly from that floating support to guide floating objects toward that floating support and to help provide an additional enclosed area, immediately ahead of that floating support, within which floating objects can be trapped.

Abstract: An x-ray tomography apparatus has a couch for a human subject to lie on, a cylindrical capsule to enclose part of the body, a flexible water filled bag to stabilize a portion of the human body being x-rayed, an x-ray source mounted on a rotatable frame, and an arcuate row of x-ray detector plates enclosed in a metal container filled with xenon gas. The detector plates are positioned on the rotatable frame opposite the x-ray source so that the x-rays pass through the subject and are received by the detector plates. The detector plates and x-ray source are continuously rotatable about the subject, having slip ring power and electrical connections. The couch is servo motor powered and is switched at the completion of one rotation of the rotatable frame to automatically index the subject forward.

The stripper plate, head plate and elastomeric material can be readily separated to allow convenient exchange and replacement of those parts.

Abstract: This invention relates to a hot water system which utilizes heat from the refrigerant of a refrigeration system to produce hot water. The utilized heat consists of the superheat of the refrigerant vapor, the heat of condensation or latent heat, and part of the sensible heat of the liquid refrigerant. The water passing through a water-cooled condensing unit, which is part of the refrigeration system, is heated to a selected temperature by removal of both the latent heat and superheat and part of the sensible heat from the refrigerant as it passes through the condenser unit. The condensing unit has a water inlet and an outlet between which is connected a hot water storage tank. As the water in the condensing unit is heated by absorption of latent and superheat and part of the sensible heat from the refrigerant passing therethrough, the heated water rises and flows by convection into the storage tank. Eventually the storage tank may fill completely with water of a selected temperature.

Abstract: The fusible element of an electric fuse has a first electrical path, a second electrical path in parallel relation with the first electrical path, a weak spot in the first electrical path which can respond to a potentially-hurtful overcurrent to fuse and thereby form a first arc in the first electrical path, and a weak spot in the second electrical path longitudinally displaced from the weak spot in the first electrical path which can respond to that overcurrent to fuse and thereby form a first arc in the second electrical path. The weak spots form primary arcs as they fuse; and one important function of those primary arcs is to establish the point at which the rate of rise of the overcurrent starts to diminish, while another important function of those primary arcs is to burn the adjacent portions of the respective electrical conducting paths.

Abstract: There is disclosed an improved strippable laminated tape particularly adapted for making carton joints, and for sealing flaps of cartons and the like, which can be easily stripped to free the joints or the flaps. The tape has a Kraft paper upper layer, preferably with filaments between the layers, and a bottom layer of low internal bond, all united, and with a longitudinal cut that may be straight, zigzag, diamond, or of other form, extending through the bottom layer. The under surface of the bottom layer may have adhesive on it. The tape is applied in usual manner to carton panels or flaps. To open the carton or separate the joint, the tape is stripped by pulling up one end, in which action the bottom layer delaminates the adhesive and parts of the low internal bond bottom layer, but due to the cut through that bottom layer, the sides or flaps are free, collapsing the carton, or providing ready access.

Abstract: A highly corrosion resistant, durable, strong, hardenable and relatively inexpensive nickel based, high chromium, high iron, austenitic alloy has greatly improved malleability and hot workability. The alloy contains approximately the quantities indicated:Ni--30-48% (preferably to 38%, to balance to 100%)Cr--30-35%Co--4-7.5%Fe--3-25% (but preferably 10-25%)Mn--1-3.5%Cu--2.5-8%C--to 0.25%And has a content of Mo from about 0 to 3%, a content of Si from about 0.3% and wherein the sum of the Mo and Si content is less than about 4%. Boron may be added to increase the workability and forging properties of the alloy. The preferred content of approximately 3% Si and approximately 1% molybdenum results in an optimum balance of the age hardenable workability, and corrosion resistant properties. All percentages are by weight.

Abstract: A heat-sensitive protector, that is connectable into an electric circuit, has an elongated, effectively non-fusing element which performs the function of a connector as long as that protector is intact, and thereafter moves fron a retracted position to an extended position to perform the function of an indicator when that protector responds to heat to open that circuit. That element spans the full distance between the terminals of that heat-sensitive protector.
