Abstract: A plural component tester for measuring the ratio of plural components delivered from a spray device during plural component spraying. The components are introduced into the tester through an elastomeric seal which separately channels each component into individual hoses. Each component is then separately advanced by the hosing and delivered to separate graduated containers which collect each component separately for easy and convenient measuring.

Abstract: A needle case for needlecraft work has a magnet on one side to allow the case to be held on the magnet board. The magnet holds the case for mounting but does not hold the needles within the case. A needle threader has a flat threader that can be inserted through the eye of a needle until an eye of the threader extends through the needle. A shoulder on the needle threader stops the needle, and a notch in the threader communicates with the eye of the threader for ease in passing yarn into the eye of the threader. The needle threader is made of a ferromagnetic material, and may be held on the magnet of the needle case. Further, the needle threader can be held on the magnet of the needle case, and remain there when the needle case is carried by a magnet board.

Abstract: A needle threader for needlecraft needles has a notch to retain a needle in position on the threader while thread is passed through the eye in the needle threader. The notch may be used in conjunction with shoulders utilized as stops for the needle, or may be used with the more conventional threader. The notch for retaining the needle allows easier threading because the threader with the needle can be held with one hand while the thread is manipulated with the other.

Abstract: An external mix, air-assisted, airless atomization, plural component spraying system and method includes a first source of a first component, e.g., a resin; a second source of a second component, e.g., catalyst for the resin; spraying means to mix the resin and catalyst and direct the mixture to a substrate; a source of compressed air; and means for injecting the catalyst into the compressed air. The spraying means includes a nozzle assembly which comprises a liquid nozzle for forming the resin into a fan-like film with expanding edges extending from a liquid orifice, and a nozzle assembly for directing a flow of compressed air and catalyst at the fan-like film colsely adjacent the liquid orifice. In a preferred embodiment, compressed air is directed to impinge upon the expanding edges of the fan-like resin stream downstream of the impingement of the flow of compressed air and catalyst particles to capture from catalyst particles in small, uniform spray pattern.

Abstract: An internal mix, air-assisted, airless atomization, plural component spraying system includes a source of resin; a source of catalyst for the resin; a spray gun to mix the resin and catalyst and direct the mixture as a spray to a substrate; and a source of compressed air to assist in atomization of the mixed resin and catalyst. The spray gun includes a mixing apparatus and an atomizer including a liquid nozzle for forming the mixed resin and catalyst into a fan-like film with expanding edges extending from a liquid orifice, and an air nozzle for forcing a flow of compressed air to converge at an elongated air orifice and expand in a fan-like flow.

Abstract: An apparatus and method are disclosed for repositioning fallen loads. In particular, the device mounts on the fork lift and has a pair of crossbars mounted on the fork lift receiving tubes. The cross members have a height greater than the thickness of the crossbars on the rack system. The fork lift operator engages the bottom surface of the pallet load with the upper surface of the cross members and lifts the pallet load until it is clear of the crossbars whereupon the load is repositioned properly.

Abstract: A label is provided consisting of a lamination of two layers. One of these layers is a printable layer capable of being heat shrunk onto a can the upper and bottom parts of which are tapered inwardly. The preferred material for this layer is polystyrene. The other layer is polypropylene the function of which is to add strength to the first layer and to trap there against the printing ink which is printed onto the polystyrene layer. The polypropylene permits undistorted perception of the printed material. The two materials cooperate to permit printing and label application processes.

Abstract: A foldable stand for holding a card or the like for easy viewing. The stand includes a base and a supporting member pivotal with respect to each other. A pivot body carries the pivot pin, and carries a stop pin that extends into the vertex between the base and the supporting member as the members are rotated in opposite directions. The pivot body also carries a trough that is aligned to carry the card or the like when the stop pin is in position to limit the rotation of the base and supporting members.

Abstract: A magnifier for use in needlework. The magnifier has magnets at each end to allow the magnifier to stick to the usual magnet board over a graph or pattern being worked on. A reference line on the magnifier provides a convenient way to keep the place being worked on, and allows a person to see above and below the line to keep the work in context with the entire pattern.

Abstract: A storage case for needlecraft materials and the like, with an extender for the case. The storage case has three sections hinged together so the case can be folded into thirds, each of the three sections having pockets for storing materials for easy retrieval. At least one section has a sub-divided pocket for receiving knitting needles. A flap above the sub-divided pocket can either cover the ends of short needles, or lie against the backing to allow long needles to pass over the flap. Another flap is positioned to cover the ends of the long needles. One end section has a large pocket opening towards the hinge. An extender is foldable about its hinge into two sections. One section of the extender can be placed into the large pocket, and the entire case can be closed as one case.

Abstract: A solar heating panel unit is provided in the form of a plastic pouch having an internal chamber provided with a serpentine path.

Abstract: A method and apparatus for continuously separating solids and liquid in a solids-liquid mixture are disclosed. In accordance with the invention, a separation zone for separating solids and liquids from a solids liquid mixture is provided in which the mixture is subjected to centrifugal force under low shear forces and low turbulence. In this zone, the flow rate is maintained to be less than the terminal settling velocity of the solids in the mixture. Further in accordance with the invention, the mixture is introduced into the separation zone from a zone of higher turbulence and higher flow rate than those of the separation zone, a minor part of the mixture in the other zone being removed to the separation zone. The major part of the mixture is removed from the other zone and discharged and returned to the mixture source in such a manner as to aerate the returned mixture. The separated solids are returned to the mixture source with the major part of the mixture.
