Abstract: A picnic cooler container is disclosed which is utilized in packaging a plurality of multiple articles such as cans of beverage or the like. The cans are inserted into the container through the ends of the container package. The container is designed to be opened by the purchaser of the container with the container being designed to receive a quantity of bulk ice placed on top of the plurality of multiple articles. The container comprises a plurality of side and end panels which have hingedly connected thereto side and end flaps which are glued down for shipping and transporting without the ice. The side and end flaps may then be pulled up and formed into an upper water-proof well area which retains the bulk ice on top of the multiple articles packaged in the lower water-proof container area.

Abstract: Joints for thermoplastic pipe. The necessity of providing a sealing ring between the socket and spigot of such a joint results in forming a ring groove in the socket and affixing the sealing ring within this ring groove. The present invention contemplates forming a sealing ring groove 6 so configured around a sealing ring 11 with a substantially axially incompressible portion 12 to lock the sealing ring in place and also to enhance the ease of assembly and ability of the thus assembled joint to structurally withstand elevated hydrostatic pressures. Also disclosed is an apparatus 20 and 44 for forming the preferred socket configuration.

Abstract: A paperboard carton formed of a tray with a top fitting thereover. The top has tabs formed in opposing side panels preferably by locating spaced tear lines, which tabs can be glued to the tray to hold the top in place. The top is removed from the tray by pulling the tabs outward and upward.

Abstract: An improved crown support carrier production blank and erected carrier for use with a plurality of beverage bottles. The production blank and the erected carrier are formed with a plurality of inclined upper side and end panels hingedly attached to a central panel and hingedly attached to a plurality of vertical lower side and end panels. A plurality of T-shaped corner glue tabs are formed in the corners of the production blank and are adhesively secured to the lower side and end panels when the production blank is erected to a completed carrier. The T-shaped glue tabs act as an exceptional reinforcing strip on the corners while their shape and placement are designed to round out or soften the corners rather than have sharp piercing corners typical in prior art carriers. Sunburst bottle receiving openings are positioned in the central panel along with at least one opening for use in carrying the package.

Abstract: A multiple article package is disclosed wherein a plurality of articles such as folded basket beverage containers having a lenticular shape are tightly banded together in a lenticular shaped bundle by at least one diagonally positioned band. The tightly banded lenticular shaped bundle of articles then are packaged in an outer restraint with the articles being utilized to carry the weight of similarly packaged articles that may be loaded on top of the outer restraints. The method utilizes the banded carriers along with the outer lightweight non-load bearing restraint to provide a novel packaging method for shipping the plurality of folded basket beverage carriers to the customer. The invention may be utilized with many types of lenticular shaped articles including the beverage containers shown in the drawings.

Abstract: This invention relates to the measurement of the temperature and/or mass flow rate of a free falling molten stream of material. Previous techniques have not recognized the effects temperature variations of the molten stream of material have on the measurement of the above flow properties. The present invention utilizes a line scan camera having photodiodes disposed in a predetermined array to measure the temperature and mass flow rate of a moving mass of molten material. This is accomplished in the present invention by limiting the maximum voltage generated by any one photodiode exposed to light energy of a mass by varying the scan rate and thus the exposure time of the photodiodes in response to a variance in the light intensity and thus the temperature of the molten mass of material.

Abstract: A thermal insulation device for insulating irregularly shaped objects such as pipe flanges and fittings is described which comprises a flexible thermal insulation member of specified dimensions adhered to a cover sheet and also containing detection means for detecting leakage from the flange or fitting to be insulated. The device is removably attached to the flange or fitting by securing means. The device thus provides efficient thermal insulation of pipe flanges, fittings and the like while permitting easy and prompt detection of any leakage from within the structure.

Abstract: The present invention comprises a low-cost, convenient to use anti-punking binder system for use in bonding entangled masses of mineral fibers such as glass. The binder system comprises a phenolic-formaldehyde resin mixed with a water soluble urea-formaldehyde resin; the urea-formaldehyde resin content in the binder system comprising an amount of about 5 to 50% by weight of the binder solids content. The urea-formaldehyde resin comprises about 59% urea, about 19% formaldehyde and about 22% water by weight. Silane, ammonia and ammonium sulfate may also be added.

Abstract: A process for the rapid annealing of refractory fiber is disclosed. Air at a temperature of 750.degree. F. (400.degree. C.) to 1400.degree. F. (760.degree. C.) is passed through a refractory fiber body for a period of 5 to 200 seconds while the body is held securely in place for dimensional integrity. Apparatus for performing the process of this invention comprises an annealing unit containing opposed foraminous platens and means for passing hot air through the platens and through the fiber body retained between the platens or opposed foraminous belts and adjacent conduits and means for passing the hot annealing air through the conduits and belts and through the fiber body retained between the belts. The process and apparatus may be used to produce fiber bodies of a single material or laminated bodies of a plurality of interlocked layers, which may be of different fiber materials.

Abstract: Apparatus for grinding a helical cutting surface on a flat cutting blade. Prior art grinders are complex, difficult to operate and expensive to use. The present grinding machine comprises a stationary support (74), a grinding arbor (76), an adjustable cam plate (78), a grinder carriage assembly (80), a grinder assembly (82), cam follower (112), mounted on the grinder carriage assembly (80), and a grinding stone (128) mounted on the grinder carriage assembly (80). When the carriage and the grinding stone are reciprocated along the axis of rotation of the grinding arbor the cam follower (112) contacts the lower surface of the cam plate (78) whereby the grinding arbor is oscillated about its axis of rotation and a helical cutting surface is ground into the blade (34).

Abstract: A process and apparatus therefor are described for the expansion of perlite utilizing vaporized heavy liquid fuel as at least half, and preferably all, of the combustion fuel. In this process preheated air is used to vaporize the liquid fuel, which has previously been atomized.

Abstract: A method of vacuum packaging compressible material in a sealed flexible fluid impervious container, such as a poly bag, is disclosed. One or more slits are made in the container and air in the container is withdrawn through the slits. This creates a partial vacuum in the container that results in compression of the compressible material. When the desired compression has been obtained, restraining means are placed around the flexible container to maintain the package in a compressed state when the partial vacuum is eventually lost. A novel apparatus for use in this method is also disclosed.
