A brace connects with a clamp that can be positioned where desired along the support member to an angle bracket which is carried by a short post welded to the deck at a location remote from the weld stud.

Abstract: A valve is provided which includes a valve body having a passageway from an inlet end to an outlet end and a tapered annular valve seat intermediate the ends, a plastic poppet being provided with a disc portion and a tapered portion which can engage the valve seat, the tapered part being stepped to provide a deflectable outer edge portion, the poppet including three beams which extend toward the inlet end of the body and are bent outwardly to enter a groove in the valve body, thereby providing resilient means to bias the poppet to a closed position. The valve body includes a transverse wall adjacent the valve seat, the wall having openings for allowing flow through the passageway and also including an opening that receives a post projecting from the poppet toward the outlet end and beyond the wall for engagement by a mating connector to displace the poppet to its open position.

Abstract: An arrangement for driving a rotary tool is provided in which the tool shank is engaged and frictionally driven by the engagement of three or more drive rollers. Axial movement of the tool is accomplished by tilting the axes of the rollers as permitted by flexible portions of the shafts which drive the rollers. The tool is released by moving one roller away from the other two. A pressure foot is provided at the bottom of the assembly reciprocated by a cam arrangement to engage the workpiece when the tool is in operation. A position pick-off senses the axial position of the tool so that the tilt angle of the rollers can be controlled by a dual feedback path servo loop having an improved preconditioning circuit for its feedback position counter.

Abstract: A downcomer shaped as a channel is attached to a four-sided stud welded to a supporting surface. The central web of the downcomer engages one side of the stud and its side flanges are spaced from two additional sides of the stud. A U-shaped member overlies the remaining side of the stud, with side flanges of the U-shaped member positioned in the spaces between the side flanges of the downcomer and the adjacent sides of the stud. Fasteners hold the assembly together.

Abstract: A high speed spindle is provided which includes a rotor driven by an electric motor and provided with tapered journals received in tapered rubber bearings. Lubricating water flows to the bearings through metered openings in the journals, flowing from the openings through reverse spiral grooves in the journals which have diminishing cross section. The water flowing through the rotor also cools the rotor, as well as the collet driven by the rotor and a tool held by the collet. Rubber seals around the rotor shaft wear to a zero clearance during run-in for confining the water that exhausts from the bearings. Compressed air is introduced into the spindle to cooperate with the seals in preventing water leakage. The compressed air also reacts against a bladder that is arranged to impose an end load on one of the bearings, which is movable, to urge the bearing toward its journal. The force is varied to increase the bearing end load as rotor speed increases.

Abstract: A closure for a beverage can is provided which includes an integral plastic member extending complementarily around the upper end portion of a can, including the side wall and end wall thereof, the member having a plug portion that fits within an opening in the end wall of the can for sealing the same. Scores in the plastic member provide weakened areas resulting in a pull tab by which the plug element is removed from the opening in the can and the closure is removed from the end portion of the can. The plug portion can be reinserted in the opening in the can if less than the entire contents are dispensed. A vent opening also may be provided in the can, sealed by a second plug portion of the can closure.

Abstract: A suspension system is provided for use with a four-sided stud welded to a supporting surface. The suspension system includes a square tube having a series of openings through its side walls. One end of the tube receives the stud and is bolted to it. The opposite end of the square tube is received between opposed channels of a bracket which has a bottom plate portion adapted to support an object. Bolts extend through openings in the channels and the bottom end of the square tube to complete the attachment.

Abstract: A container of draft beer is substantially filled with beer having a volume of dissolved carbon dioxide greater than 2.6 and not more than 3.1 times the volume of beer. The beer is packaged in a plastic container that is slightly permeable to carbon dioxide, but retains a satisfactory dissolved carbon dioxide content even after a normal shelf life. Beer is dispensed by gravity, without use of external pressure source, after release of head space pressure. Moreover, when the container contents are partially dispensed by the consumer and then maintained at appropriate low temperature for several days, the remaining beer still retains a satisfactory volume of dissolved carbon dioxide. A spigot on the container employs a barrel valve closure member that seals the pressurized container and is movable to a pressure release position in which pressurized gas within the container is slowly released without forcibly projecting container contents.

Abstract: A luggage case is constructed from four flat extruded plastic beams having ribs on one surface, and four inside corner pieces that include tongues extending into the recesses defined by the ribs. Fabric fits over the frame thus provided. Exterior corner pieces overlie the corners of the fabric and are attached to the inner corner pieces. The corner pieces extend the full width of the case to support the fabric. Wheels may be provided to allow the case to be pulled. Cases of different sizes are produced by cutting a plastic extrusion to form beams of different lengths. The same corner pieces are used for cases of all sizes.

Abstract: A neck covering is provided for a jacket or other garment including a member attached at its central portion near the inside of the collar of the garment, with side portions projecting outwardly in either direction which can be wrapped around the neck of the wearer. Fasteners on the ends of the side portions secure the neck covering in place. The central part of the covering is constructed to attach to the lining of the jacket, which may be provided with a slot adjacent the attachment of the neck covering to permit the neck covering to be pushed through the slot and stowed in back of the lining when not in use.

Abstract: This invention provides a dispenser for a beverage, such as beer, in which the contents of the container are pressurized by gas from a cartridge in the container. A pressure responsive member in the container is movable in response to differences in pressure between that of the atmosphere and of the inside of the container. A valve member is carried by the pressure responsive member and includes a tapered pin for forming an opening through a diaphragm over the cartridge outlet and metering the discharge of gas from the cartridge in response to movements of the pressure responsive member.

Abstract: A sanitary can cover is provided which extends over the top portion of a beverage can and includes a severable strip along its lower edge which allows the cover to be peeled back so that the can may be opened. Only about half of the cover can be folded away from the end of the can, the remainder of the cover being adhesively secured to the can. The cover may include a plug sealing an opening in the end wall of the can, and a pull tab to assist in removing the plug from the opening.

Abstract: A garment is provided which has air scoops adjacent the wrist portions of the sleeves of the garment defined by a longitudinal opening interconnected by an outer web, and an inner web connected to the material of the sleeve at spaced locations on either side of the opening. A flap is included to extend over the outer edge of the scoop when it is not to be used, and which may be secured to the inner layer of the scoop when the scoop is in use. The garment may include an air-pervious lining and a discharge opening on the back of the garment for allowing air received in the scoops to flow along the arms and discharge from the garment.

Abstract: The fluid dispensing device includes a tubular spout attachable to a fluid-containing vessel, such as a bag, the spout including an outer end portion of a first lateral dimension and an inner portion of a smaller lateral dimension. A valve member is slidable in the spout, the valve member being tubular and having an open outer end adapted to receive a fluid-transmitting probe and a closed inner end. The valve member has openings through its sidewall. The outer end portion of the valve member is laterally outwardly deflectable and includes localized protrusions adapted to enter the recess of a probe. In the closed position of the valve member, opposed shoulders of the valve member and of the spout resist axial movement of the valve member in either direction, and interengaged sealing surfaces block fluid flow to the openings. The outwardly deflectable portion of the valve member can be deflected as the probe enters, and the protrusions thereafter spring inwardly into the recess of the probe.

Abstract: A support is provided for attachment to a four-sided stud welded to a supporting surface. The support includes a tube carrying a lower member adapted to connect to an item to be supported. The upper end of the tube is collapsed and given a U-shaped configuration so that it can extend around a portion of the stud. Fasteners hold the upper end of the tube to the stud.

Abstract: A valve assembly is provided which is in two units, each of which assumes a normally closed position when the units are separated and is opened when the units are mated. One unit includes a valve body with a transverse wall having an opening therethrough which is normally closed by a diaphragm which is provided with openings through it outside of the location where it engages the wall. The other valve unit includes a valve body having a spring-biased plunger which at its end has an integral pin engageable with the diaphragm when the units are advanced toward each other for deflecting the diaphragm away from the opening in the transverse wall, and an additional projecting portion for engaging the transverse wall to cause the plunger to be deflected away from the valve seat, thereby to open up communication through both valves.

Abstract: The box construction includes superimposed layers or flaps each of which has a cut partially through it from the surface adjacent the other, the cuts being aligned. Glue within the cuts holds these box portions together, allowing them to be separated by tearing out only the part within one of the cuts, resulting in a neat appearance without loose shreds. Alternatively, the inner layer may be cut all the way through around an enclosed periphery, held to the remainder of the layer by at least one uncut segment interrupting the cut. Glue within the periphery secures the inner layer to the outer. When the layers are separated, the center within the periphery of the cut is torn out, adhering to the outer layer. The layers may be returned to their original positions where the center enters the cut and holds the layers together by friction. Box closures and spouts are included.

Abstract: A spigot for association with a spout connected to a container, the spigot including a cylindrical portion to fit over the end of the spout, a diaphragm for engaging the end of the spout to prevent flow of liquid, a toggle member for deflecting the diaphragm and an opening through the cylindrical portion for dispensing liquid upon the deflection of the diaphragm. The spigot includes a downspout extending from the opening and having a sealed outer end which is of a relatively thin-walled construction, the downspout having a thicker wall inwardly of the outer end to prevent collapse of the downspout during deflection of the diaphragm. The spigot member includes a relatively thin-walled portion inwardly of the thickened part of the downspout for facilitating deflection of the diaphragm. The spigot may be sealed by heat sealing together opposed wall portions of the downspout or by a tab heat sealed over the end of the downspout.
