Title: Valved nozzle for re-usable reservoir of a flowable product
Inventor: KLAKURKA HENRYK
IPC: B65D35/38
Filed: 1992-01-07
Granted: 1999-06-01
Abstract: A re-usable nozzle for dispensing a flowable product from a resilient container has a removable one-way valve which facilitates cleaning and sterilisation of the nozzle.  When the nozzle is used for dispensing a flowable pharmaceutical, the nozzle controls the amount of suck hack of pharmaceutical into the nozzle on completion of dispensing.  With a stand off of the valve float from the valve seat during dispensing of about one eighth of an inch (1) the suck back is sufficient to draw any drop of contaminated pharmaceutical at the tip of nozzle on completion of dispensing into the nozzle so as to reduce the risk of contamination of the environment and (2) the suck back is sufficiently small to minimize the risk of damage to any tissue with which the nozzle is intimately associated.  Furthermore, with the distance from the valve seat to the nozzle tip being at least  about  three  times  the  stand  off,  no  contaminated pharmaceutical may enter the container so that the container may be re-used.  The nozzle cavity supports an O-ring which acts as a valve seat and has an integral annular abutment which acts as a stop for the valve float.  The float has a hemispherical end directed toward the valve seat and a plurality of legs directed toward the float stop.  Flutes formed between legs provide fluid communication through the nozzle when the ends of the legs abut the float stop.  The O-ring, and then the float, may be removed.

Title: Alternate master bursting data rate management techniques for use in computer systems having dual bus architecture
Inventor: ENG ROBERT CHIH-TSIN
IPC: G06F13/36
Filed: 1992-05-05
Granted: 1996-10-22
Abstract: Methods and apparatus are set forth which optimize and balance the use of processor card (or complex) resources (e. g., memory, the local bus, etc .), with the use of other system resources, such as the card to card communications bus and devices attached thereto, in dual bus computing systems. A new data rate management technique reduces data transfer overhead particularly for burst mode transfers. The invention promptly services pending memory refresh requests; limits multiple accesses to on card (or processor complex) memory by an Alternate Bus Master to a predetermined number of cycles where the processor requests the use of its local bus; and allows an Alternate Bus Master unlimited accesses to the processor local bus when the Alternate Bus Master owns the card to card communications bus and the processor subsequently requests that bus. The aforementioned balance of resources is achieved using a Bus Hold On Grant ("BSHOG") scheduling procedure which, assuming a bursting Alternate Bus Master has gained control of the local processor bus and is conducting data transfer cycles when the processor requests the local bus, allows the Alternate Bus Master to conditionally retain local bus ownership over a plurality of Alternate Bus Master data transfer cycles.
