Abstract: A sand molding machine comprises an elongated tie rod with a removable bearing sleeve portion at its distal end. The distal end of the rod where the sleeve is attached has a reduced diameter end spindle portion with multiple stepped support sections on its outer surface. The sleeve is of generally hollow cylindrical configuration and fits over the spindle end portion of the rod. The sleeve has an outward cylindrical bearing surface, and an inward surface with stepped support sections corresponding to and contacting the outside support sections on the rod when the sleeve is attached. The respective supporting sections on the rod and the sleeve provide a strong tight attachment of the sleeve to the rod without requiring excessive force in order to attach and/or remove the bearing from the rod.

Abstract: A system for filling orders in a warehouse utilizes a main conveyor for routing items in the warehouse, including to a primary and secondary picking area. The primary picking area is used for picking high volume items, and is subdivided into multiple subgroups of primary pick faces. The second picking area is used for picking items that are not available for picking in the first picking area. Picking is performed in alternating short pick periods. Picking from a first subgroup of primary pick faces is performed in a first pick period, and picking from the second subgroup of primary pick faces is performed in an alternating pick period. Items are assigned to the first picking area dynamically for each picking period on the basis of which items are the highest moving items during an individual pick period. The system utilizes a pivotally mounted diverting chute to direct items into the pick faces, etc., and a self opening pick face.

The covering has special advantage when used with a bunk bed having extended bedposts and a footboard or headboard, to provide a snug, neat look. The covering is generally rectangular, with at least two corners having "cutouts" forming end and side flaps. The cutouts align with the bedposts. The end flap extends downward at the end of the bed, and the side flap extends downward along the side of the bed. Elastic tabs with fasteners are located at each of the corners with cutouts to unfastenably and elastically attach the end flap and the side flap together and retain the bedspread snugly and neatly on the bed.

Abstract: An in-line electric heater for heating fluids, such as paint, moving in a conduit has a thermally conductive massive body in which is formed a fluid passage having an inlet port and a outlet port. An electric heating element in the body directly heats only the upstream portion of the fluid passage and heater body. The downstream portion of the fluid passage and heater body is indirectly heated to a substantially lesser temperature by heat conduction from the upstream portion whereby the downstream portion acts as a "thermal accumulator" which damps the cycling, overshoot and undershoot of the temperature of the fluid at the outlet port of the passage.

Abstract: An electrostatic spray coating gun has an improved high voltage charging system which includes a flexible and resilient electrode in the form of an elongated coil spring. This form of electrode substantially eliminates the likelihood of scratching or puncturing the skin of an operator or repairman, and allows the electrode to return to its proper orientation after being bumped, while exhibiting good paint charging characteristics for use in electrostatic spray coating.

Abstract: An electrostatic spray gun is disclosed which comprises a high valued resistance in the barrel portion of the gun, and a second resistor in the nozzle of the gun closely adjacent to a charging electrode projecting from the nozzle to provide safer operation.

Abstract: An airless liquid spray nozzle is disclosed which has a safety guard extending therefrom in order to prevent the nozzle from coming into close proximity with the skin of a human operator, repairman, or the like. The conduit supplying liquid is valved by a normally closed valve responsive to air pressure or other control medium. The control medium supply communicates with a passage or path in the extending portion of the safety guard. Therefore, if the guard is not attached to the nozzle or becomes substantially broken, air leakage causes the supply of air to the valve to be reduced to such an extent that the valve stops hydraulic flow to the nozzle. In the preferred embodiment, the control medium, e.g. air, is supplied to the normally closed valve through a path or conduit which passes through the extending portion of the guard before reaching the valve.

Abstract: A digital control system is disclosed for activating a responsive device, such as a dispenser, at a preselected time after an initiating event, for a predetermined duration period. The system can be used for example in the packaging industry to apply adhesive at precise locations on a box moving on a conveyor. The system automaticaly compensates for conveyor speed and for the pull-in time and/or drop-out time of the responsive device.

Abstract: A machine for the coating of a strip material substrate, flat stock or the like has a plurality of spray coating guns applying coating material to the substrate. A sloping ceiling and nozzle support assembly causes any coating material deposited thereon to flow along these surfaces to the side of the substrate rather than collecting above the substrate and dripping on the substrate and degrading the desired finish. In a rotary coater, the sloping ceiling and nozzle support assembly can be combined into one rotating structure wherein centrifugal force arising from the rotation of the structure causes any coating material deposited on it to travel to its outer rotating edge where it is thrown clear of the substrate. Troughs over the entrance and exit openings of the coater collect coating material which would otherwise drip onto the substrate from above the openings and carry such coating material clear of the substrate.

Abstract: A cartridge type safety goggle for welding is disclosed having an improved ventilation system. A cover plate, gasket, filter plate and retaining spring are held in a cartridge, which is adapted to be inserted into a goggle body. A plurality of ventilating holes on the top and bottom of both the goggle body and the cartridge combine with a plurality of tabs on the cartridge to provide an air flow path which provides improved ventilation for the inside surface of the filter plate and yet prevent objectionable light from entering the interior of the goggle.

Abstract: An electrostatic spray coating gun for applying coating materials which have high to moderately high electrical conductivity is disclosed. The gun has an improved high voltage electrical system, improved hydraulic seals, and is adaptable to apply porcelain enamel coatings in slurry form. The gun has a flexible and resilient electrode in the form of an elongated coil spring. This form of electrode substantially eliminates the likelihood of scratching or puncturing the skin of an operator or repairman, and allows the electrode to return to its proper orientation after being bumped, while exhibiting proper paint charging characteristics for use in electrostatic spray coating. The electrode is positioned forward of a flat-fan spray nozzle and is displaced from the axis of the spray by means of an extension assembly which can be angularly displaced about the axis of the spray.

Abstract: In a hand held electrostatic type spray coating gun a removable cartridge lengthens the paint supply conduit between the base of the grounded handle and the barrel so that the gun can be used to spray paints which have moderate electrical conductivities such as those containing metallic particles. The cartridge includes a Teflon tube in the form of an elongated spiral. Fluid connections at each end of the cartridge allow the cartridge to be easily removed and stored, and a straight conduit substituted for it when it is not needed, for example when the gun is to be used for nonconductive paints. The location of the cartridge facilitates removal, and combines with the gun to provide a well balanced device for hand held operation.

Abstract: A nozzle tip with a cylindrical body is held in a nozzle tip holder by means of a thin walled tapered bushing. The nozzle tip is pressed into mechanically sealing engagement with the inside surface of the smaller end of the bushing, the bushing in turn being press-fit into mechanically sealing engagement with a cylindrical passage in a nozzle tip holding member.

Abstract: Disclosed is a static seal suitable for sealing a pull rod or the like to an opening through which the rod passes into a hydraulic conduit. This static seal can be used in a wide variety of apparatus including for example spray coating guns, both electrostatic and non-electrostatic, valve assemblies and the like. Novel static sealing arrangements at each end of a non-machined extruded bellows provide packingless bellows sealing between the rod and the opening. Such a sealing arrangement is compatible with the highly desirable materials of the fluorinated hydrocarbon group, commonly known by the trade name Teflon.

Abstract: A high-voltage electrical cable comprising a core of alternating solid non-brittle resistors and flexible conductive links sheathed in a moderately flexible dielectric material has the relative physical dimensions of the components selected such that the mechanical stresses in the assembly are minimized if any loop in the cable were inadvertently pulled in such a way as to put a kink in the cable.
