  • Patent number: 5630762
    Abstract: Bowling pins formed by molding a plastic shell about a foamed plastic core have not heretofore come into practical use because of inability to withstand shocks in service, resulting in separation of the shell from the core. According to the present invention, a foamed thermoset (non-melting) copolymer is employed for casting the core. Thereafter, before casting a plastic shell thereabout, the core surface area is substantially increased by simply removing the core surface skin, thereby opening the outermost thermoset core cells for filling by the shell material.

  • Patent number: 5478541
    Abstract: The present invention provides a method for separately removing mercaptans and hydrogen sulfide from a hydrocarbon gas stream by passing the gas through a bed which includes iron oxide which catalyzes the formation of disulfides and trisulfides from mercaptans and also reacts with at least part of the hydrogen sulfide to form acid-stable solids; causing the di- and trisulfides to exit the bed in the gas phase; and removing and recovering the di- and trisulfides by adsorption or condensation. Any remaining hydrogen sulfide may be scavenged from the gas stream by passage through a bed containing iron oxide similar to that used first above. If the gas stream contains substantial amounts of hydrocarbon aerosols, they should be filtered out in advance of the bed.

  • Patent number: 5462089
    Abstract: Rectangular sheet metal duct sections with integral outwardly-and-rearwardly formed end flanges are conventionally made from coiled strip metal to lengths provided by the width of the coil stock, ordinarily slightly less than five feet. As is common practice, outward-and-reverse facing flanges are formed on both ends of each wall of the duct section. The spaces between the flange ends at the corners of the duct section are filled by heavier cornerpieces having arms projecting at right angles. Crimping the outstanding flanges over the corner arm portions completes a duct section. According to the present invention, a linear array of embossed surface portions is formed in the duct wall close to each outwardly projecting flange portion and beneath its reverse-facing portion.

  • Patent number: 5388391
    Abstract: A new apparatus is provided as part of a system for use in hospitals and the like, which safely stores and packages biohazardous wastes. The upper portion of the apparatus includes a pneumatically operated descending pressure plate and anti-pathogen provisions. The lower portion encloses a slide-out compartment in which disposable waste containers are placed. Bags containing such wastes are deposited in the container from time to time and are continually exposed to ultraviolet light, while air is drawn away for filtering and safe discharge. When several bags of waste have been so deposited, a planar divider for the waste container is pressed downward, gently leveling the bags of waste beneath it, while the air expelled is sprayed with an anti-pathogenic spray. These operations are repeated using a succession of such dividers until a container has been substantially filled; it is then removed for disposal. Novel safety features are incorporated in the pneumatic circuitry.

  • Patent number: 5380080
    Abstract: A display case for reflective articles includes a base preferably having upward-sloping side edges and a transparent enclosure. Within the enclosure is an upward-and-aft sloping display ramp. A downward-and-aft sloping mirror extends from the top of the enclosure at least to the level of the top edge of the ramp. This mirror may be the forward surface of a rear wall of the enclosure. Viewers both at a substantial distance from and close to and above the case will see not only the articles displayed on the ramp, but also at least portions of their reflections in the mirrored surfaces. The mirror also serves to reflect some ambient lighting onto the display ramp.

  • Patent number: 5358013
    Abstract: Modifying that type of integral flange outstanding from a sheet metal duct characterized by an outstanding first width of sheet metal and a second substantially equal width bent reversedly back to extend at from the first, in the present flange a sheet edge margin is bent reversedly back and inwardly between the second and first such widths. As compared to prior art flanges, this results in substantially lessened deflections under internal duct pressures without appreciable increase in sheet metal used. An added advantage is that the sheet metal edge is positioned so that it cannot endanger workmen's hands.

  • Patent number: 5353616
    Abstract: For closing Pittsburgh-type rectilinear seams, as in conventional sheet metal heating and air conditioning ducts. The present machine, with only a single seaming roll, closes seams through to on an advancing stroke, and burnishes them on the return stroke. The machine functions without adjustment throughout substantially the entire range of sheet metal thicknesses normally utilized. Of particular advantage in manufacturing duct sections having integral end flanges, only an initial short length of seam need be peened manually before the duct elements to be seemed are clamped in place for completion. Workplace noise is greatly reduced.

  • Patent number: 5354239
    Abstract: A method for forming a plastic composite bowling pin includes removing the surface skin of a foam core, mounting a plastic base ring on such core, and molding a relatively thick elastomer shell around the prepared core and the base ring so that the hardening of the shell interlocks the shell, core and base ring. A pin made by this method is easily refurbished by removing the base ring and part of the shell and re-molding the surface of the shell.

  • Patent number: 5340381
    Abstract: An operating system for dual-sieve oxygen concentrators, as used by invalids, provides a method and apparatus for controlling the purging and release of product gas and the cycling period in response to the pressure build-up in each sieve column. The cycling period is thereby self-adjusting to changes in the capacity of the columns. Restricting flow of product gas and purge gas to the higher-pressure part of the adsorption period provides product gas of higher purity and reduces the loss of oxygen in the purge.

  • Patent number: 5320992
    Abstract: A mineral carrier for those iron oxides which react to remove hydrogen sulfide and mercaptans from fluid streams. The new carrier avoids the problem encountered with wood chip beds of bed solidification which occurs when reacted oxide particles adhere to each other. Calcined montmorillonite, for example, possesses the necessary crush strength, porosity, insolubility in water and wettability, to maintain bed perviousness and avoid caking as reaction continues to the full capacity of the oxide.

  • Patent number: 5277109
    Abstract: This invention is particularly useful in food processing for separating crumbs and particles of breading material which have become suspended in frying oil, so that the oil may be reused. Separation is done in a unique cylinder having a hollow piston, whose forward end has a screen and whose aft face is imperforate. The cylinder has an openable door at its forward end. Near its end door the cylinder has a liquid inlet and a liquid outlet spaced somewhat aft therefrom. When the piston is in its retracted position its screen end is positioned axially between the inlet and outlet, so that the liquid may pass through the screen. Air pressure in the portion of the cylinder aft of the piston acts against its imperforate face to drive it forward. The screen end of the piston filters and drives the liquid back to the outlet, solids are compacted against the door.

  • Patent number: 5264194
    Abstract: Non-hydrated iron oxides utilized in moistened permeable beds to react hydrogen sulfide present in natural gas do not totally lose their reactivity when the beds give up their moisture to dry gas. Lessening of their reactivity attendant to dryness is signalled by a rise in H.sub.2 S level in the gas at or somewhat in advance of the reactor outlet. On such signal water is injected into the inflowing gas stream, reviving the bed's reactivity and permitting continuation of gas sweetening until the reactive potential of the oxide is substantially fully utilized, with minimal water addition.
