Abstract: The present invention provides for an improved diaphragm pump having two material pumping chambers. The material pumping chambers are operated by two working fluid chambers which are separated from the material pumping chambers by two diaphragms. The diaphragms are interconnected to provide that the two material pumping chambers alternatively receive and discharge the material to be pumped. A control valve controls the stroke reversal of the improved diaphragm pump. The control valve is actuated by the pressurized working fluid which is being discharged from a pressurized fluid chamber. Further valving provides for a portion of the pressurized working fluid being discharged from a pressurized fluid chamber to be reused and introduced into the exhausted fluid chamber to initiate expansion of the exhausted fluid chamber. The pre-pressurization of the exhausted fluid chamber reduces the amount of source air required at the beginning of the stroke.

Abstract: A container and closure construction featuring double means of liquid tight-sealing with a threaded closure so arranged as to double seal combined or sequentially against two separate areas of the rim of a container neck to provide sealing properties even when closure is partially unscrewed from the top of the rim of the container. A preferred embodiment has its application of the above arrangement together with child proof safety closures having unique safety locking arrangements in the form of coincidentally registered abutments and projections formed in and/or on said container and closure which do not substantially interfere with applying the closure to the container but which can be disengaged only through purposeful mind-controlled dextrous manipulation.

Abstract: A spray nozzle is disclosed. The nozzle includes a central opening through which air and material issues. A pair of horns are located on a first center line plane extending through the opening. The outwardly projecting horns include converging air ramps which induce an air flow. The atomizing air openings of the nozzle are positioned outside of opposed sectors which define a predetermined angle and are symmetrical with respect to a center line plane perpendicular to the first diameter. The nozzle limits material deposits and clogging of air openings located in the horns.

Abstract: A method of forming parisons in machines for making glass bottles which includes introducing a gob of molten glass into a blank mold, moving a cavity plunger to form a parison cavity and subsequently subjecting the gob to a predetermined pressure separate from the cavity plunger to apply pressure urging the molten glass into conformity with the mold.

Abstract: The invention disclosed relates to a method of making laminated products such as furniture, cabinets, counters, and the like. A laminate formed of thermosetting polyester saturated on paper of 8-12 mil thickness is bonded with a thermoplastic, thermoforming acrylic saturated on paper of 12-18 mil thickness. The bonded layers are shaped over at least two surfaces angularly positioned relative to each other. For examples, the bonded layers are shaped around sharp corners or edges of a substrate, such as conventional fiberboard, particle board or wood, under heat and pressure. A hot melt adhesive, preferably coated on the inner surface of the bonded laminate attaches the laminate to the one plane surface of the substrate and bending pressure is applied as the substrate and laminate pass through a series of rollers to bend the laminate in degrees around the corners and into contact with the other surface of the substrate. Pressures are in the 20-200 psi range and at temperature in the range of 350.degree.-450.

Abstract: An improved flood lighting fixture for a horizontally mounted HID lamp is disclosed.

The T-shaped bracket is fixed to a desired mounting surface and the mating plate is fixed to the end of a lighting fixture intended to engage the mounting surface. The mounting plate and bracket cooperate to suspend the fixture in a first position below and spaced from the mounting surface while wiring is installed and in a second position against the mounting surface after installation is completed.

Abstract: A method for manufacturing glass bottles is disclosed which includes consecutively delivering gobs of molten glass into a blank mold, forming each gob into a parison, transferring the parisons alternately into at least two sets of blow molds, allowing said parisons to reheat, and expanding the parisons in the blow molds. The sets of blow molds reciprocate along a substantially vertical path. A first position where the parisons are alternately received by the blow molds and blown containers removed is located on the vertical path. The parisons are expanded and cooled in the blow molds by blowing them out or by applying a vacuum, or a combination of those means at a second position on the vertical path.

The security plate extends around three sides of a wood lock-side jamb member to which it is mounted in order to enhance the impenetrability of the door by preventing splitting of the lock-side jamb and resultant dislocation of the strike plate and keeper during thrusts against the door. The strike plate is adjustable without removing the security plate to accommodate slight variations in the size or shape of the door or frame during seasonal or atmospheric changes.

Abstract: The present invention is a slip spline seal assembly for sealing the ends of a splined shaft and complementary sleeve. The assembly includes a flexible body having alternating projections and intervals for meshing engagement with the spline shaft. Recesses are located on the sealing surfaces of the flexible body to provide pockets for lubricating medium and reliefs for displacement of body material when it is compressed, thereby decreasing wear and tear and promoting a longer useful life of such seal assemblies. The assembly also includes means for locking engagement with the complementary sleeve, and for completing the sealing of the spline connection between the shaft and the sleeve.

Abstract: A spill preventing diaphragm attachment for a paint spray gun paint cup as shown. The diaphragm is engaged around the mouth of the paint cup and forms, with the undersurface of the paint cup lid, a chamber above the paint in the cup that is deeper at one side than the other. At the deep side, oriented 180.degree. away from the vent opening in the lid is a vent opening in the diaphragm. Any paint that might flow through the diaphragm vent opening as a result of tipping the spray gun drains back into the cup as soon as the gun is righted. The diaphragm is readily replaceable without tools.
