Abstract: ABSTRACT OF DISCLOSURE         Disclosed herein is an ignition system com-prising a coil mounted on a core having first and second spaced legs, together with a rotor mounted for rotation, under normal operating conditions, in one direction re-lative to the core such that any point on the periphery of the rotor passes the first leg prior to the second leg.  The rotor includes a magnet having arcuately spaced first and second poles and first and second pole shoes extending respectively from the first and second poles.          In addition, the first pole shoe extends in spaced re-lation from the second pole shoe in the direction of normal rotor rotation and has an arcuate length which is greater than the spacing of the first and second legs, and is effective, incident to travel of the first pole shoe past the first and second legs, to cause initial flow of flux of one direction into the coil core so as to generate in the coil a first current pulse of one polarity and thereafter to cause outflow of the flux from the coil core so as to generate in the coil a second pulse of the opposite polarity prior to approach of the second pole shoe to the first leg.

Abstract: ABSTRACT OF THE DISCLOSURE      A firmware/hardware mechanism in a general purpose computer system automatically provides alternate addressing paths for addressing data in the same or another main memory module when a failure is detected in a portion of the main memory or main memory module.  Two types of memory failures are detected and an alternate path provided for each type of failure.  The first type is a failure in a memory which is not detected by memory hardware or system interface unit SIU hardware; such failure is handled by an exception processing mechanism to provide an alternate path to a good memory module.  The second type of failure is detected by memory hardware or system interface unit SIU hardware; such failure is handled by an interrupt processing mechanism to provide an alternate path to a good memory module.

Abstract: ABSTRACT OF THE DISCLOSURE        A method of manufacturing a magnetic head comprises the steps of providing a pair of core block pieces each having an abutting area and a gap defining surface which is slightly recessed relative to the abutting area, disposing the pair of core block pieces in a manner that the gap defining surfaces are located opposite to each other and the abutting areas are held in abutment against each other, thereby defining a gap between the gap defining surfaces, placing a quantity of a gap forming material such as glass, ceramic, enamel or the like within or adjacent to the gap, heating the gap form-ing material to cause it to melt, cooling the core block pieces, upon completion of permeation of the gap forming material into the respective gaps, to solidify such material, thereby providing a core block, cutting and/or slicing the core block into cores of a given size, winding a coil on the individual cores, and fixedly mounting each of the cores with the coil thereon in a housing to provide a magnetic head.          In the magnetic head thus formed, the gap in the core is defined by the pair of gap defining surfaces, at least one of which is bevelled.  A desired gap length is obtained by cutting the core at an optimum position along the length of the gap defining surfaces or along a suitable cutting plane as defined herein.

Abstract: VALVE WITH SELF-RETAINING VALVE SEAT                ABSTRACT OF THE DISCLOSURE A valve body has a closing member rotatably mounted in a passage for opening and closing said passage. An annular groove having a substantially dove-tailed cross sectional portion is formed in said valve body for receiving an elastomeric annular seal ring. Said groove is positioned so that the seal ring is engaged by the periphery of the closing member when said closing member is in the closed position. The annular seal ring includes a pair of annular axially extending arms disposed on each side of said seal ring and an annular spring member embedded in said seal ring and extending into the axially extending arms so that when the seal ring is disposed in the groove the spring member forces said arms into engagement with the dove-tailed portion of the groove thereby rendering the seal ring self-retaining. The seal ring and groove are formed so that a space is provided between the arms and the main portion of the seal for trapping pressurized fluid that leaks passed the seal, said fluid exerting additional sealing pressure on the arms.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved sorter control system for controlling modular sorting assemblies which receive copy sheets from a duplicating machine and distribute the sheets into bins to form collated sets of document information being reproduced. The control system uses two cam operated switches in con-juction with two contacts of a relay which change state as a sheet of paper interrupts a light beam in each of the modular sorter assemblies.  In this manner both the lead edge and the trail edge of a copy sheet break the light beam upon entering a bin causing an index mechanism which controls the sequence of opening the gates for each of the bins to advance.  The gate last opened directs copy sheets to the next modular sorting assembly to continue the sorting opera?ion in an expedious manner.

Abstract: TITLE:  BED WITH AUTOMATIC TILTING OCCUPANT SUPPORT       Abstract of the Disclosure A bed including an open supportive framework pivotably mounting an occupant support platform for movement between a horizontal and an upright position.  The bed includes a drive mechanism and associated motor with controls to enable selective movement of the platform between the two positions.  The drive assembly includes a lead screw operatively connecting the open framework to the platform.  A nut pivotably mounted on the framework threadably receives the screw which, when turned, causes pivotal movement of the platform between the two positions.  The frame-work is open at a foot end of the bed to enable an occupant to move freely toward or away from the support platform.  The platform includes a foot rest assembly that may be selectively moved longitudinally rela-tive to the platform between an operative and inoperative position. In the operative position, the foot rest may be utilized to receive and support  the weight of the occupant.  The inoperative position of the foot rest assembly allows free movement of the occupant's feet.  Safety provisions assure that the platform cannot be pivoted past either posi-tion, that the platform cannot fall during a power outage, and that the motor will not operate unless the foot rest is in the operative position.

Abstract: IMPROVED TRAY STRUCTURE            Abstract of the Disclosure An improved square tray structure in which a series of trays can be stacked one on top another when the trays are loaded, and which can be nested one within another when the trays are empty.  The tray's end walls are of a height about one-half that of the tray's side walls, the end and side walls all extending up from the tray's floor.  The tray's floor is positioned closely adjacent the tray's bottom edges.  The tray's side walls each include a top rail and a top rib extending along the top edge thereof, and a bottom rail extending along the bottom edge thereof, the rails and rib being linear and ex-tending from adjacent one end to the other of the side wall.          The tray's end walls each include a middle rail and a middle rib extending along the top edge thereof from adjacent one end to the other of the end wall.  In use, and when the trays are stacked, the trays' side walls are oriented into a vertical coplanar attitude so that a bottom rail of an upper tray seats on a top rib and rail of a lower tray on each side thereof for supporting the trays in that stacked relation.  When the trays are nested, the upper tray is rotated 90° relative to the lower tray so that the upper tray's bottom rails seat on the lower tray's middle ribs and rails, and so that the upper tray's middle rails seat on the lower tray's upper ribs and rails, for supporting the trays in that nested relation.  The top, middle and bottom rib and rail structures cooperate with the trays' walls to prevent end-to-end, as well as side-to-side, movement of the upper tray relative to the lower tray when the trays are in stacked, as well as in nested, relationship with one another.
