Abstract: ABSTRACT            Virtual Memory Terminal A microprocessor controlled terminal (1) with keyboard input (4) and CRT display output (6) employs virtual memory and store management techniques to enable an operator to run any of a wide variety of different applications (e.g. text, image, graphics, data entry, reservation, payroll etc.) in the terminal.  Application procedure records and data records relating to a selected application are copied as required from a local backing store (14) and/or over a communications link (9) from a main store (16) of central processing unit (12) into a dynamically managed region (20) of random access memory (RAM)  (3) under control of primitive microprocessor control instructions permanently held in read-only store (10).  In view of the virtual memory techniques employed, the backing store (14) and main store (16) appear to be logical extensions of RAM (3).  The records copied to region (201 are contiguously stored as variable length segments in successive free storage locations and are chained together for subse-quent access in a plurality of double-threaded chains. Previously marked procedure (and possibly data) are copied from region (20) into directly addressable fixed location (19) of RAM (3) and serve to configure terminal (1) to inter-act with data and procedure in region (20), in accordance with the requirements of the selected application.  Con-tiguity of segments in region (20) is restored following disruption caused during running of the application.  Storage management techniques provide for store-through of segments in RAM (3) to the backing store (14) and main store (16) and identifies segments within RAM (3) available for deletion from RAM on a least-recently-used basis to provide additonal space for new segments.

Abstract: 12                  48,651 ABSTRACT OF THE DISCLOSURE     A method and apparatus for supplying lubricant to turbine bearings during normal and abnormal operating modes.  A pump coupled to the turbine's rotor discharges lubricant during normal turbine operating modes through an ejector from its inlet port through its outlet port.  The lubricant transmitted to the ejector's inlet port is mixed with lubricant withdrawn from a lubricant reservoir during its transmission through the ejector and such mixture is discharged  from  the ejector's  outlet  port  at  a  supply pressure.  The lubricant mixture is routed to the turbine bearings and the lubricant pump's suction side.  When the supply  pressure  falls  below  a  predetermined  value,  a clutch is engaged which couples a constant  speed drive input  linkage to the turbine rotor.  The constant speed drive also has an output linkage whose speed is maintained at a constant predetermined value  for varying rates of speed on the input linkage.  The output linkage is coupled either to an auxiliary lubricant pump or an electrical generator.  The auxiliary lubricant pump discharges lubri-cant into the inlet port of the ejector and takes suction from the outlet port of the ejector.  Electricity gener-ated by the electrical generator operates an electrical motor which drives an auxiliary lubricant pump which takes suction  from the  lubricant reservoir and discharges the lubricant to the turbine bearings.

Abstract: ABSTRACT Apparatus (10) draws a continuous length of shrink tubing (23) from a reel (22) cuts off a section (6), and advances it onto the terminated end (9) of a lead (5) carried by an adjacent conveyor (40). This is accomplished by shear blades (94, 95) integral with jaws (86, 88) which close on the end of the tubing (23) to sever a section (6) and contain it and shape it between the jaws (86, 88).  The jaws (86, 88) move vertically in a plate (85) which is then advanced horizontally toward the lead (5).  A feed clamp (102) which descends with the jaws (86, 88) draws the continuous length (23) forward, then releases vertically as the jaws (86, 88) depart and a stationary clamp (112) grips the tubing while the jaws (86, 88) and clamp (102) return over the tubing (23) for the next shearing and advance operation. Above motions are effected by levers (66, 74, 78, 82) and a slide (127) driven by followers (145, 141, 143, 147, 139) riding in cam grooves (144), 140, 142, 146, 138) on discs (70, 73) carried by a single shaft (71). The end of the lead (5) with tubing section (6) thereon is transported laterally through a hot air duct (34) type heater having slots (36, 37) which permit passage of the lead (5) therethrough.

Abstract: ABSTRACT OF THE DISCLOSURE    A convertible child-resistant closure comprises an outer closure and an inner resilient liner.  When applied to a co-operating container in the child-resistant mode, the resilient liner is distorted between the container rim and abutments formed on a panel of the outer closure, thereby providing an upward locking bias to the closure.  The upper surface of the liner in-cludes depressions adapted to receive the abutments only when the liner and the outer closure are in a particular relative angular orientation.  To convert the assembly to a closure which is not child-resistant, the liner is removed and reoriented so that the abutments are received within the depressions, thereby preventing the abutments from distorting the liner to provide the locking bias.

Abstract: SENSOR TRAVERSING DEVICE            ABSTRACT     A grouping system (10) is provided for grouping pans (12) containing raised dough moving from a proofing zone to an oven (18) for baking.  The grouping system (10) permits the grouping of the pans at a speed approaching the speed of movement along an unloading system (14) and the oven-ready conveyor (24).  However, impacts between individual pans during grouping and the first pan in the group contacting the gates (20) forming the group is at a slower combined speed, less than the speed where damage to the risen dough becomes a significant concern.  The grouping system (10) includes parallel conveyor belts (28) for conveying the objects from the unloader system (14) to the oven-ready conveyor (24).  Accelerator belts (21) may be employed to accelerate the pans between the conveyor belts (28) and the oven-ready conveyor (24) to provide a gap between each pan moving on the oven-ready conveyor.  A group end sensor (64) is moveable along the grouping system (14) between the conveyor belts (28).  The sensor includes both forward and rearward sensors (128, 130) for sensing the proximity of pans at a predetermined separation in the direction of travel.  A full forward limit switch (140) senses the movement of the group end sensor to its full forward limit proximate the gates (20).  A full rearward limit switch (154) senses movement of the group end sensor to its rearwardmost extent.  The group end sensor moves forward until is forward limit is reached or the forward sensor senses an object representing the last stopped pan.  The conveyor then moves at full speed until the rearward sensor senses the following pan.  The conveyor speed is then reduced so that the pan contact does not damage the dough.  A full group limit switch (150) is provided to sense the stoppage of a preselected number of pans forming a group.  When operated in the group mode, this will then permit the gates (20) to be opened if the oven-ready conveyor (24) is moving to move the group onto the oven-ready conveyor.  If the grouping system is operated in the random mode, the gates will be opened for a selected time interval whenever the oven-ready conveyor (24) is moving.  If a group of pans pass onto the oven-ready conveyor (24) before the elapse of this time interval, the gates (20) will close upon movement of a subsequent pan proximate the gates (20).
