Abstract: ABSTRACT OF THE DISCLOSURE      A wound dressing and delivery means laminate composite is described comprising contiguously oriented and coplanary arranged discrete layers.  A centrally-disposed wound dressing layer is in separable and releasable contiguous adhesive contact through an adhesive surface with an adjacent surface of a release liner layer.  A non-adhesive surface of the wound dressing layer is in separable and releasable contiguous adhesive contact with an adhesive surface of the delivery means layer.  In using, the release liner layer is first peelably separated from the adhesive surface of the centrally disposed wound dressing layer within which it is in releasable contact.  Next, the remaining adherent wound dressing layer and delivery means layer of the wound dressing composite are positioned over the wound application site and applied to the site by contact adhesion.  Finally, the delivery means layer is peelably separated from the adjacently contiguous adhering surface of the wound dressing layer.

Abstract: ABSTRACT A composite, heavy-duty spool with plastic end cones, consisting of a cylindrical spool body of thick, rigid, heavy cardboard having open ends, and a pair of plastic end cones. When dismantled, the end cones can nest in each other so as to occupy little space. Each end cone comprises a truncated, conical body portion all parts of which are essentially of uniform thickness. At its small base part, each body portion has a transverse wall that is apertured to receive a draft bolt, and has a plurality of integral strengthening ribs each of which is disposed both on the conical exterior and on the transverse wall exterior. The ribs lie in planes which pass through the axis of the body portion, and are shaped to effect a lead-in formation at the aperture of the transverse wall, to guide a draft bolt to the aperture. The advantage of the present construction over the devices of the prior art are that the spool is rust-resistant, light-weight and yet sturdy, and the individual parts readily lend themselves to quick assembly so as to keep the manufacturing and storage costs low.

Abstract: ABSTRACT           A process for forming a metal or metal com-pound coating on a face of a hot vitreous substrate in sheet or ribbon form by continuously advancing the substrate in a downstream direction along a path through a coating station which discharging droplets of liquid coating precursor material in the downstream direction so that such material contacts the substrate at the coating station and continuously withdrawing vapours thereafter from the coating station in the downstream direction and annealing the substrate, is characterized in that the hot coated substrate passes from the coating station to an annealing lehr via a re-heating station at which sufficient radiant heat energy is supplied to the hot coated substrate to raise the temperature or the mean temperature of its coated surface at the re-heating station through a certain temperature range, at least the upper end of such range being not less than a temperature 100°C below the temperature or the mean temperature of such surface immediately before its contact by coating precursor material.  The apparatus for performing such a process is characterized in that at a position between the coating station and the annealing lehr there is a re-heating compartment which is separated from the coating station by at least one boundary wall, which compart-ment is provided with radiant heating means for heating the substrate as it advances past such compartment.

Abstract: ABSTRACT OF THE DISCLOSURE             A vending or dispensing machine is operable in triple depth, double depth, and single depth operating modes.  A cradle which is rotatable through 360° is used to separate cylindrical articles from a number of tandem nonstaggered vertical columns.  The rotatable cradle separates a single can or other cylindrical article from each of the columns disposed in a storage zone above the cylindrical cradle and drops the cans into an escrow zone.          One of the cans in the escrow zone is immediately dispensed.  If operating in a triple depth mode, the remaining two cans are held by side mounted pivotable escrow members which are controlled and movably operable by the cradle itself.  Upon a second activation the cradle moves further in its sequence allowing one of the escrow members to release its hold on a second can such that that can drops into a dispensing zone accessable to a consumer.          A further activation of the cradle causes it to release the second escrow member such that the third and last can in the escrow zone is released for gravity movement into the dispensing zone.  The cradle then rotates around and segregates three more cans from the columns as the sequence starts over.  The side mounted escrow members or gates have a camming surface to advance the point in the operating sequence at which the escrow members are moved to holding positions.  A peg arrangement or mounting flange arrangement is used to lock the removable escrow members against removal by unauthorized persons.

Abstract: ROTATION-PREVENTING DEVICE FOR AN ORBITING   PISTON-TYPE FLUID DISPLACEMENT APPARATUS          ABSTRACT    A rotation-preventing/thrust-bearing device for use in an orbiting-member fluid displacement apparatus is disclosed. The rotation-preventing/thrust-bearing device includes a discrete fixed por-tion, a discrete orbital portion and bearing elements. The fixed por-tion includes a fixed race and ring placed in a groove in an inner surface of the housing. The fixed race and ring are attached to the housing by pins, and the inner peripheral edge of the groove is caulked to the fixed ring. The orbital portion includes an orbital race and ring placed in a groove in an end plate of the orbiting member. The orbital race and ring are attached to the end plate of the orbiting member by pins, and the outer peripheral edge of the groove in the end plate is caulked to the orbital ring. A plurality of pockets are formed axially in the rings toward the respective races. The pockets of the rings face one another in generally aligned pairs. A bearing element is received in each aligned pair of pockets to prevent the rotation of the orbiting member by the bearing elements interacting with the orbital and fixed rings and to carry the axial thrust load from the orbiting member. The rotation of each ring, which is caused by protation-preventing operation, is prevented by both the pins and the caulked connection.

Abstract: ABSTRACT      A process for treating a sulfur-containing gas stream such as the Claus process off-gases by hydrogenation of unreduced sulfur followed by selective hydrogen sulfide absorption resulting in a vent gas that can be discharged directly to the atmosphere without incineration.  A gas stream containing substantial unreduced sulfur values relative to the total sulfur concentration in the stream, is passed to a hydrogenation zone along with a hydrogenous gas.  The gas stream may be first passed to a hydrolysis zone within which reduced sulfur values are hydrolized to produce hydrogen sulfide and carbon dioxide and the effluent from this zone then applied to the hydrogenation zone.  The feed from the hydrogenation zone is cooled and passed to an absorption zone where it is contacted with an aqueous solvent which preferentially absorbs hydrogen sulfide in the presence of carbon dioxide.  The absorption solution comprises an alkaline hydrogen sulfide absorbent and an acid having a pKa of 6 or less in a concentration to protonate 0.1-22% of the alkaline absorbent.  The gas stream from the absorption zone is discharged to the atmosphere without prior incineration.  Specifically disclosed solvents include solutions of alkanolamines in combination with organic or inorganic acids present in an amount to protonate 2-13% of the absorbent.
