Title: Scheduling input/output operations in multitasking systems
Inventor: MIRO FELIX
IPC: G06F9/50
Filed: 1991-09-11
Abstract: SCHEDULING INPUT/OUTPUT OPERATIONS        IN MULTITASKING SYSTEMS Abstract Of The Disclosure In a multitasking system,  I/O requests to a disk are staged in holding queues from which they are transferred to a service queue. Requests in the latter queue are directly serviced on a FIFO basis by a device driver in the system. The  system  maintains  a  set  of  holding  queues  and  an associated service queue separately for each physical drive (hard file, floppy drive, etc.). Holding queues in each set are prioritized in accordance with base priorities of tasks, and  I/O  requests  to  disks  are  entered  into  associated holding queues having priorities corresponding to those of task  threads  for  which  such  requests  are  originated. Prioritization  of  the  holding  queues,  and  a  starvation advancement process performed to advance "oldest" enqueued requests  to  higher  priority  holding  queues, causes  the requests to be presented to the disk in a sequence based in part on respective task priorities and in part on "fairness" servicing  of  "service  starved"  requests.  A  selection operation in respect to certain transfers from the holding queues to the service queues orders selection of transferred requests  on  the  basis  of  relative  proximity  of  disk addresses in the queued requests to current positions of the read/write  head  assembly  in  the  associated  disk  drive. Foregoing operations serve to improve processing throughput of all tasks.  A service kernel  of the operating system, which maintains the holding queues, places each newly issued disk I/O request in a selected holding queue associated with a  designated  disk.  The  selected  queue  is  one  having  a priority  associated with  the  base  priority  of  the  task thread. A request issued for a foreground task may be placed in a higher priority holding queue than requests of like priority issued for other tasks. When entering a new request into a holding queue,  the kernel performs a "starvation" check relative to selected holding queues.  If a starvation condition  is  detected,  the  kernel  performs  the  above-mentioned  starvation  advancement  operation  to  transfer requests in the affected queue to a higher priority queue.

Title: Driven ring-type non-return valve for injection molding
Inventor: OAS DAVID C
IPC: B29C45/52
Filed: 1992-02-14
Abstract: ABSTRACT OF THE INVENTION      A non-return valve for an injection molding machine is provided  which  includes  a  conventional  tip/stud  member threaded into the end of a plasticating screw and carrying therewith an annular valve seat member.  An annular check ring  receives  the  tip/stud  member.   Tang  protuberances axially extend from the check ring to rotably engage the retainer end of the tip/stud member.  This causes the check ring to couple with the tip member during screw rotation to minimize valve wear while  permitting the  check ring  to axially move relative to the tip member for effecting valve closure by pressure differentials in the normal manner.  A ramp surface is provided on the tang protuberances which engages a drive surface on the retainer end of the tip/stud member upon reverse rotation of the screw through a prede-termined rotational angle or for a set time to positively close the valve prior to injection.

Title: Regulated delay line
Inventor: LOU PERRY W
IPC: H03K5/00
Filed: 1992-06-15
Abstract: REGULATED DELAY LINE                  Abstract of the Disclosure Three delay lines may have common characteristics.          The first delay line delays the rising edge of an input signal and a first inverter inverts this signal to provide a falling edge.  A second inverter inverts the rising edge of the input signal to produce a falling edge which is introduced to the second delay line in a second path with the second inverter.          The signals from the two paths may be introduced to a comparator which produces a control signal having logic levels dependent upon the relative times that the falling edges occur for the signals in the two paths.  For example, the control signal may have the first logic level when the falling edge occurs first in the first path and the control signal may have the second logic level when the falling edge occurs first in the second path.  The voltage from a charge pump is adjusted in accordance with the logic level of the control signal.          This voltage is introduced to the first and second delay lines to adjust their delay to minimize the time difference in the falling edges of the signals from these lines.  This voltage is also introduced to the third delay line to adjust its delay in accordance with the adjustments in the delays in the first and second lines.  In this way, the third delay line provides the same time for rising edges and falling edges in data signals introduced to the line.
