Abstract: ABSTRACT OF THE DISCLOSURE         A high speed sorting system includes a plurality of induction conveyors capable of depositing cartons sequen-tially and in a spaced relationship onto a merge conveyor.          The merge conveyor includes a pair of angled roller sections which bias each carton toward the center of the merge con-veyor for intake onto an alignment conveyor.  The alignment conveyor includes a plurality of angled rollers and thereby biases each carton toward one lateral edge of the conveyor.          Each carton is then discharged onto a main outlet conveyor which includes a plurality of longitudinally spaced diverter mechanisms.  Positioned adjacent each diverter mechanism is a destination conveyor.  A control system is provided for proper sequencing of each carton onto the merge conveyor and for operation of the diverter so that each carton may be directed to a preselected destination conveyor.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved type of centrifugal separator for separating liquids such as oil and/or water from a mixture of gas and liquid.  It consists of an upright cylindrical shell divided by transverse dividers into three chambers.          The mixture of gas and liquid is introduced through a tangential diverter into the lower chamber to produce a high velocity vortex of gas and liquid.  A central axial vortex tube penetrates and is sealed through both transverse dividers.  This vortex tube is comprised of two spaced longitudinally aligned portions which define a gap between them.  The gap is positioned inside the central chamber.          The upper end of the vortex tube extends into the top chamber and is sealed into a first mist extractor.  The lower end of the vortex tube extends into the lower chamber.    Due to the vortex action the liquid is thrown outwardly against the inner wall of the shell, the gas forming a high velocity vortex column along the central axis of the shell.  This gas column moves upwardly through the central axial vortex tube.  Entrained liquid is thrown outwardly against the wall of the tube by centrifugal action and is drawn into the central chamber through the gap between the two sections of the vortex tube.  The gas continues to move upwardly into the first mist extractor.  Here it is passed through a tortuous passage between elongated vertical obstacles such that the liquid is scrubbed out against these surfaces.  The gas then passes through a second mist extractor, and essentially liquid free gas passes out an opening in the top of the shell.

Abstract: TRANSMISSION TRUNK MULTICHANNEL          DISPATCH SYSTEM WITH PRIORITY QUEUING                      ABSTRACT      A communication system of the type wherein a central station assigns a limited number of information channels to a requesting one of a plurality of remote stations is dis-closed.   The requesting station sends its identification signal along with the request signal to the central station on a signal channel.  The central station classifies the requesting station in either a priority or a nonpriority queue.  The priority queue corresponds to those stations which are continuing an on-going interchange, whereas the nonpriority queue contains those stations which wish to initiate an interchange.  Stations are prioritized in the queues on a first-in/first-out basis.   The central station constantly monitors the information channels and, as channels become available, assigns the channels first to stations in the priority queue, then to nonpriority queue stations.  A channel becomes "available" when the central station detects a pause, such as a momen-tary release of a push to talk microphone switch, in trans-mission on that channel.  By this transmission trunking method, the system makes optimum use of the limited number of available channels.    Additional central station processing provides an acknowledgement signal, which indicates that the request was received and a channel will be assigned as soon as one becomes available.  Also, the identification of a requesting station is compared with an associate memory.  The memory provides the identifications of all stations to whom the requesting station would transmit. Once a channel is avail-able, it is assigned to the requesting station and to its associated stations, whereby the associated stations are notified of, and prepared for, the impending transmission.

Abstract: ABSTRACT OF THE DISCLOSURE         In oil and gas well pumping apparatus, a polish rod reciprocates through a stuffing box and connects to a submersible pump through a tubing string or the like.  When servicing, it is desirable to close off the gas or oil pressure from below and hydraulic fluid is routed from a remote location to the blow out preventer.  The blow out preventer consists of a cylindrical casing with a cap screw threadably engaged to the upper end thereof and containing a cylindrical spool or the like formed from elastomeric material having an annular channel around the outer peri-meter which is operatively connected to the source of hy-draulic fluid.  When it is desired to close off the blow out preventer, hydraulic fluid is pumped under pressure to the channel thus forcing the center of the spool in-wardly and clamping same around the polish rod thereby closing off the passageway around the polish rod.  O rings surround the spool above and below the channel and assist in sealing.  Upper and lower steps in the casing slope outwardly and away from one another to facilitate the re-turn of the spool to the normal position when pressure is released.

Abstract: ABSTRACT OF THE DISCLOSURE:     An apparatus and method for sealing a flow control apparatus, such as a damper, suitable for controlling the flow of fluids in a conduit, especially high temperature gases in flue ducts.  The damper includes a closure member which may be removed entirely from the fluid steam by sliding movement through an aperture.  Fixedly mounted, cooperating, flat, resilient strips seal the aperture in both the open and closed positions of the damper.  Resilient support strips on both sides of the sealing streips control the resistance to flexure of the sealing strips.  The sealing strips include means for effecting buckling thereof to change the sealing stripsfrom a condition of concave bending with respect to the interior of the fluid passageway to a condition of convex bending with respect thereto whereby damage to the sealing strips is preven-ed.  The resistance to flexure of the sealing strips is control-led to ensure that the seals will not be opened by pressure or vacuum within the fluid passageway when the closure member is in the open position.

The gas generator includes in some embodiments a minimum of fuel so that a maximum amount of oxygen in the generator is capable of being liberated. The oxygen is liberated by the combustion of a fuel at localized positions in a refractory binder, which has the property of prev-enting the molten salt residue from becoming molten and the oxid-izer from flowing and thereby preventing the combustion from becoming extinguished.          The gas generator includes a suitable clay as a binder. coke as the fuel and a chlorate such as sodium chlorate or potas-sium chlorate as the oxidizer.  The binder is included in the generator in the range of approximately seven per cent (7%) to fifteen per cent (15%) by weight, the fuel is included in the generator to an amount of approximately twenty five per cent (25%) by weight, depending upon the use to be made of the genera-tor, and the remainder constitutes the oxidizer.
