Abstract: Abstract of the Disclosure Disclosed is a method and apparatus for recycling asphalt concrete roadways by adding little or no new hot mix to the recycled surface.  The apparatus includes means for heating the roadway and applying emulsified asphalt thereto prior to scarifying the heated surface.  The surface is then scarified so as to loosen the heated asphalt.  The scarified material is then treated with asphalt and, if desired, a rejuvenating agent.  They are mixed thoroughly to form a hot mix of asphalt concrete from the old road material. The rejuvenated hot mix is leveled by means of screws and then compacted substantially by a vibrating screed.  The screed has a continuous bottom plate and a plurality of relatively movable upper sections which are connected by turnbuckles adapted to be adjusted for bending the bottom plate of the screed to conform to the contour of the road crown.  Final compaction of the road surface is obtained by rollers.

Abstract: A METHOD OF MAKING A CELLULAR CORE         WITH INTERNAL SEPTUM               Abstract of the Disclosure A method of making a panel for installation in the high velocity air flow region of an engine nacelle and other applications requiring sound absorbing material and increased air frame strength.  The panel utilizes a single layer of either a metallic or nonmetallic cellular core with a solid or perforated septum disposed internally there-in.  The septum may have a planar or nonplanar configuration within the individual cells of the core thereby providing means for reducing the noise level of various sound frequencies created by a jet engine or any other sound producing devices for that matter.  The planar or nonplanar septum provides structural stabilization and/or vibration dampening to a bonded sandwich assembly.  The panel may also be used in strengthening air frame construction and other applications besides sound attenuating panels.

Abstract: ABSTRACT OF THE DISCLOSURE          Improved self-grinding valve is provided with corrosion-protecting features and an improved floating coupling between the valve stem and valve disc whereby, when the valve disc is brought into contact with its seat, a selected rotation of the valve disc will produce a grind-ing of the seat, followed by a disengagement of the valve stem from the valve disc.  When this disengagement takes place, the full torque load of the stem can be imposed upon the valve disc to obtain the desired seating of the same.  The valve stem is advantageously comprised of improved telescoping and threadedly engaged sections that operate to relieve the forces used to hold the valve disc against the seat upon the initial opening of the valve whereby the amount of torque required to ultimately rotate and free the valve disc from its seat is materially reduced and seizing of the valve disc relative to its seat avoided.

Abstract: ABSTRACT            IMPROVED FEED MECHANISM FOR SEQUENTIALLY SEPARATING DOCUMENTS, SHEETS, COUPONS AND THE LIKE      Documents in a stack are loaded into a bin from which an endmost document is fed by some means to a generally cylindrical drum having a high friction surface which is rotationally driven about its cylindrical axis.  A plurality of resilient continuous stretchable friction belts of lower friction than the high friction drum surface are arranged parallel to one another around pulley supports positioned such that non-friction circumferential areas around cylindrical drum surface stretch the path of continuous belts between adjacent pulleys.  The continuous belts are driven in the opposite direction from the high friction cylindrical surface of the drum.  The opposed moving surfaces separate adjacent sheets while the belts apply a normal pressure to a document on the high friction surfacce so that it draws the endmost document from the stack and carries the separated single document through the mechanism by itself.

Granted: 1983-03-08
Abstract: Abstract of the Disclosure A process is provided for producing elemental sulphur from a hydrogen sulphide and sulphur dioxide containing gas stream by a Claus type of catalytic reaction. The process is based on the discovery that the conventional Claus catalyst. in the presence of liquid sulphur and at pressures considerably greater than one atmosphere, is significantly active toward the Claus catalytic reaction. Thus, in accordance with the inven-tion, increasing the pressure of the reaction in the presence of liquid sulphur increases both the catalytic activity and the elemental sulphur conversion. The process involves introducing a compressed hydrogen sulphide and sulphur dioxide containing gas stream into a catalytic reactor and reacting the gases in a Claus catalyst bed in the reactor to produce elemental sulphur under conditions of temperature and pressure such that water in the reactor exists only as water vapour and sulphur vapour is condensed in the catalyst bed, being removed therefrom as a liquid. The pressure within the reactor is preferably between 5 and 50 atmospheres absolute.

Abstract: Abstract of the Disclosure A vertical conveyor comprising an upstanding support including spaced-apart, horizontally spaced, vertically disposed side frame members.  A platform for supporting the object to be conveyed is positioned between the frame members and is vertically movable thereon from a lowermost position to an uppermost position.          A first elongated power cylinder is mounted on the support adja-cent one of the frame members and is substantially vertically disposed.  A piston is positioned within the first power cylinder and has cables secured thereto which extend outwardly from oppo-site ends of the cylinder.  The cables are connected to the upper and lower portions of the platform so that downward movement of the piston in the first power cylinder will cause the platform to be vertically moved upwardly and so that upward movement of the piston in the first power cylinder will cause the platform to be vertically moved downwardly.  A first limit switch is mounted on the support and is engaged by the object when the object has been placed on the platform while the platform is in its lowermost position.  Actuation of the first limit switch causes the first power cylinder to be actuated so that the platform is raised from the said lowermost position to the said uppermost position.  A horizontally disposed second power cylinder is mounted on the support adjacent the upper end thereof and has a push-off rod movably mounted therein which is movable from a retracted position to an extended position.  The push-off rod pushes the object on the platform onto a discharge conveyor when the platform has been raised to its uppermost position.  A second limit switch is mounted on the support and is closed when the platform reaches its uppermost position to actuate the second power cylinder so that the object is pushed from the platform onto the discharge conveyor.  A third limit switch is positioned on the discharge conveyor and is closed by the object as the object passes there-over so that the push-off rod of the second power cylinder is retracted.  The object then engages a fourth limit switch which causes the first power cylinder to be reversed so that the plat-form is lowered to its lowermost position so as to be able to receive another object thereon for the next cycle.
