Abstract: MANUALLY OPERATED SPRAY PUMP          Abstract of the Disclosure A reciprocating type of finger pump for use on top of a product container.  This combines a tubular housing, including a laterally directed spray nozzle, mounted coaxially in the sleeve of an accumulator cap including a central valve.          The valve opening leads to a dip tube which passes into a liquid reservoir in the container.  The tubular housing, including the spray nozzle, is depressed manually so that it moves telescopically in the accumulator sleeve, driving a hollow piston against the tension of a spring.  The first compression stroke serves to prime the pump, forcing a piston to close the valve to the dip tube.  Simultaneously, air in an annular chamber of the housing surrounding the hollow piston is compressed.  On the reverse or suction stroke, the valve to the dip tube is opened, creating a vacuum which causes the liquid to be sucked up from the reservoir and into the hollow piston.  On the second or subsequent compression strokes, the compressed air and liquid are forced through normally closed pressure responsive seals into the inner mixing chamber, where the compressed air breaks up and atomizes the liquid, causing the atomized spray to move at high pressure through the spray nozzle.  Simultaneously, the valve to the dip tube closes, air is drawn into and compressed in the outer annular chamber, and the cycle is ready to be repeated in response to the successive release and reapplication of pressure on the tubular housing.  Means is provided in response to rotation of the cylindrical housing relative to the accumulator sleeve for locking the pump against compression for shipping or safety purposes.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for pressure welding together novel aluminum or magnesium workpieces.  Edges of workpieces to be pressure welded together are aligned with each other by abutment and one workpiece retracted from the other a predetermined distance to define an open channel between the edges.  The work-piece edges are quickly heated to a temperature within the range of from about 200° to 900°F. by passing a uniform flow of heating gases through the channel such that the edge tip and sides of each workpiece are softened while the edge inner cores remain cooler and harder with their mechanical properties unaffected by the heat and the workpieces then moved into abutment with each other to close the channel and immediately pressed together under high pressure for expulsion of softened metal containing deleterious materials such as surface oxides and creation of a solid-phase weld bond between the relatively cool and hard inner cores.  An air curtain can be provided to improve control of the heating of the workpieces and to enhance pressure welding together of workpieces of different gauges and of different metals, such as welding of aluminum to magnesium alloys.

Abstract: ABSTRACT OF THE DISCLOSURE     The article being wrapped has a sheet of wrapping material draped over it so that it hangs down on each lateral side thereof.  Initially the article travels on a conveyor which supports it along a central region. Thereafter the article is transferred to two supports which form part of two endless series and which travel with the conveyor.  The supports are displaced laterally towards the conveyor while travelling with it until they are located beneath the edge regions of the article. The relative levels of the conveyor and supports are then changed so that the article is transferred to the supports. The supports and/or mechanical ploughs and/or air blasts overlap the hanging portions of the wrapping material along said central region.  Thereafter the article is transferred to a further conveyor which engages the central region and holds the overlapping portions in place.  Alternatively, air blasts can be used for this purpose, and where plastics film is being used, the air can be heated to seal the overlapping portions together.
