Abstract: A thin wall blow molded plastic container includes a generally rectangular body, a cylindrical spout, generally flat neck panels tapering from the container body to the spout and container support members integrally formed in the sides and neck panels of the container. At least one first support member is provided on at least two opposed sides of the container which extends from the bottom of the container across the associated neck panel and terminates proximate the spout. Preferably four second support members are provided each of which extends from the top of the container body along an intersection of the neck panels terminating proximate to the spout.

Abstract: A method of testing coating integrity of containers includes the steps of introducing a probe into an electrolytic solution into the container and applying a constantly-increasing voltage to the probe from a source and taking readings of the voltage when the current flow through the container reaches a predetermined level. The apparatus also includes a gripping mechanism for producing a positive contact between the metal in the container and the remainder of the circuit.

Abstract: An aeration and filtering system for an aquarim includes a porous filter bed that is spaced above the tank bottom with pump means located in the chamber defined below the filter bed and having an upper inlet for receiving oxygen-enriched liquid from adjacent the liquid level in the tank and at the same time receiving oxygen-deficient liquid from adjacent the bottom of the tank. These two liquids are then mixed within the pump to provide an oxygen-enriched liquid which is fed through a discharge port that is directed generally parallel to the liquid level and slightly below to provide an exercising environment for aquatic life.

Abstract: A buckle resistant end for containers which is formed with an inwardly bowed countersink wall, a countersink groove defined by two unequal radii and a central panel wall stretched taut by accentuated doming.

Abstract: A substrate such as a single crystal gas turbine blade is given a protective coating by composite electrodeposition of a metal matrix M.sub.1 containing particles of CrAlM.sub.2, where M.sub.1 is Ni or Co or Fe and M.sub.2 is Y, Si, Ti, or a rare earth element. The preferred matrix is Ni or Co or NiCo and the preferred particles are CrAlY. The particle size is important and preferably 75% by weight are between 3.9 and 10.5 .mu.m. The coating is heat treated to produce interdiffusion between the constituents of the matrix and the particles.

Abstract: A tray-type freeze drying device determines the end of a first stage of a freeze drying process by regularly and drastically reducing the pressure surrounding the product being freeze dried. No decrease in product temperature during the reduction in pressure indicates the completion of the sublimation of water from the product and the end of the first stage of drying. A decrease in product temperature during the drastic reduction in pressure indicates the need to continue the sublimation procedure and the first stage of drying.

Abstract: A barbeque kettle includes a bowl and a cover with the bowl having a food support grid adjacent an upper rim and a charcoal grid below the food grid along with a cover holder adjacent the rim of the bowl. The cover has a removable thermometer that can sense the initial temperature of the kettle and can also be used as a food thermometer. A pair of charcoal baskets are positionable on the charcoal grid for direct or indirect cooking.

Abstract: An apparatus for detecting ophthalmic disease such as a cataract in the lens of a patient's eye includes means for focussing a laser beam and slit light alternatively or simultaneously at a selected spot in the lens of the eye. The slit light is used in a monitoring or adjustment mode to illuminate the selected spot and its adjacent portion on which the laser beam is to be focussed for ophthalmic disease detection, thereby making easier the identification of spots to be measured in the lens of the eye.

Abstract: A die necking method and apparatus for producing a smooth tapered wall between the container side wall and a reduced diameter neck includes a plurality of rotatable necking turrets that each have a plurality of identical necking substations each having a necking die. The necking dies in the respective turrets have an internal configuration to produce a necked-in portion on the container which has a first arcuate segment integral with the container side wall and a second arcuate segment integral with the reduced diameter neck. The necking substations also have a floating form control element that engages the inner surface of the container to control the portion of the container to be necked. The necked-in portion is reformed in each succeeding turret by dies to produce a smooth tapered wall between the arcuate segments.

Abstract: A drawn and ironed container having a reduced neck around an upper open end has a bottom profile which exhibits excellent strength characteristics and nests with an end double-seamed to the open end of the container. The bottom profile includes a center spherical dome surrounded by a U-shaped annular portion defining a lower support surface for the container. A joining segment is integral with the container side wall and the U-shaped annular portion includes a first annular arcuate portion having an exterior radius and a second annular arcuate portion having an interior radius.

Abstract: A multi-tiered, multi-station carrel unit includes spaced side walls that define a plurality of compartments divided into work stations by an intermediate deck, each work station having a work-supporting surface and a seat defined therein. A stairwell leads to the upper work stations and the carrel units may be assembled in any desired pattern.

Abstract: A product dispensing apparatus includes a support having a tray system supported thereon and the tray system includes front and rear walls interconnected by side walls and having a plurality of adjustable partitions extending between the front and rear walls to produce side-by-side trays. A guide member is located in each tray and slidably supports a pusher member which is biased toward the front wall. The support defines a stop to move all of the pusher members toward the rear wall when the tray system is moved from a product dispensing position to a product restocking position on the support.

Abstract: A non-venting propellant filling and sealing valve is adapted to be seated in a propellant filling hole in a bottom wall of a container and permits pressurization of a container through the hole and thereafter seals the container. The propellant filling and sealing valve includes an umbrella sealing portion, a stem portion and shoulder portions in a collar around the stem portion. The umbrella sealing portion is employed to selectively engage, separate from, and then make a generally annular seal with the interior surface of the bottom wall of the container. The stem portion is used to position the umbrella sealing portion around the filling hole and has axially extending grooves therein for conducting pressurizing fluid to the interior of the container.

Abstract: A laminating system includes a pair of heated laminating rollers for drawing laminating film from supply rolls and preheat members between the supply rolls and the laminating rollers with the rollers being heated by circulating oil. The preheat members have surface area consisting of a synthetic resin polymer having areas of chromium interspersed therein. a single-sided laminating system is also disclosed with a laminating roller covered with a chromium-synthetic resin polymer.

Abstract: A linerless cap closure includes circular top wall and a depending annular skirt having an internal thread with a tamper-evident band below the skirt. A sealing member is integral with the lower surface of the top wall and includes an annular protrusion having a depending annular axial projection. The tamper-evident band is connected to the skirt with a plurality of spaced tear tangs and a permanent connection and the band has an inwardly-directed bead with inclined ramps extending from the inner edge of the bed to the lower edge of the bead.

Abstract: A dispensing device includes a base having an upstanding post with a gripping means on the upper end biased to a first position and movable to a second position. The hollow post telescopingly receives a roll of articles separated into individual segments and the gripping means can be pushed from the first positon to frictionally grip the roll between the base and the gripping means so that the article can easily be separated from the roll without any rotation of the roll.
