A fluid transfer device such as a reciprocating pump, preferably of the diaphragm type suitable for use with an airless spray-gun for painting and the like, having a pumping side for the fluid to be pumped and a driving side driven through a piston through a solution or mixture of liquid and gas, such as oil and air. Under throttled or standby operation conditions, reduced diaphragm movement is accommodated without changing the piston stroke by reducing the volume of the driving liquid and by re...

A hermetically sealed package material and method of making the same which includes a breakaway or peelable seal formed between first and second layers of packaging materials. The first layer of packaging material includes a backing member, preferably formed from lightweight paper stock, which is bonded to a saran film or coating while in a supercooled state by a suitable adhesive, such as, for example, an adhesive selected from the group consisting of styrene-butadiene latex compounds, vinyl pr...

A reinforced fiberboard container having a plurality of reinforcing pads adhesively attached to its vertical sidewalls. Each reinforcing pad has a height substantially less than the height of the attached sidewall, and the method of adhesive attachment is such that sidewalls of the container are bowed inward in a region vertically adjacent the reinforcing pads. When the container is made of outer and inner units, the pads are preferably disposed between the sidewalls of the units but may also be...

A flashlamp having a small bulb volume (preferably less than 1 cc.) conta a filling of metal foil shreds, preferably of zirconium, of small cross section of 2 to 10 .times. 10.sup.-.sup.4 mm..sup.2, which have from 8 to 50 sharp bends, forming acute angles, preferably from 12 to 30 bends per 100 mm. of shred length to effect point contact between the filling and bulb wall. The radius of curvature of the bends is preferably smaller than 0.3 mm. and the angle formed by an individual bend is prefer...

A nut member having a relatively smooth walled aperture for receiving a male threaded member, and a pair of radially extending spiral lip portions adjacent the opening to the aperture, which receive the threaded portion of the male member and guide it into the aperture, forming a female thread. The male threaded member may have an unthreaded cylindrical end which has a diameter approximately equal to the diameter of the aperture, which is the pitch diameter of the threads, which prevents inadver...

A fitting for nonpressure pipe is formed by using a pair of identical half sections wherein each half section is formed by molding a filled thermosetting resin reinforced with glass fibers and the pair of half sections are joined in mating relationship by a layer of adhesive.

Antibiotic enhygrofungin producible by culturing Streptomyces hygroscopicus var. enhygrus var. nova in an aqueous nutrient medium. Enhygrofungin inhibits the growth of various fungi. For example, it is active against Cryptococcus neoformans and can be used to treat pigeon roosts to inhibit this fungus which has been found in pigeon droppings.

A carton having a bottom wall, a plurality of vertical sidewalls, and a top wall foldably connected to one of the sidewalls. The top wall has extension flaps foldably connected thereto which are held against the exterior top portions of associated sidewalls by a plurality of tabs extending from the top edges of the sidewalls and cooperating fastening tongues defined by nonrectilinear cuts in the top wall. The exteriorly arranged extension flaps prevent outward bulging of their associated sidewal...

A one piece, plastic clamp formable from extruded stock. The clamp comprises a pair of lever arms merged toward one end through an integral bight portion, to form a generally U-shaped member. Releasably locking fulcrum means are positioned between the free and merged ends of the lever arms. The releasably locking fulcrum extends the full width of the clamp. The cross section of the clamp through every plane perpendicular to the extrusion axis is identical in every essential respect.

The invention relates to manufacture of a V-type pulley and the pulley construction. Several embodiments of both the method of manufacture and pulley construction are disclosed. Basically, all of the embodiments have in common the use of the pair of sheet metal discs as the starting blanks for manufacturing a single pulley. The discs are progressively formed into a final pulley in three stages. In the first stage, the metal discs are formed into nesting blanks forming an intermediate preclinched...
