Patent CA-2046739-A1 (CA)
Title: Coated solid medicament form having releasability in large intestine
Inventor: SEKIGAWA FUJIO
IPC: A61K47/38
Filed: 1991-07-10
Abstract: A coated solid medicament form suitable for oral administration having reliable releasability of the active ingredient only in the large intestine is proposed. The medicament form is prepared by coating a core solid medicament form containing the active ingredient first with a chitosan having a specific degree of deacetylation and a specific degree of polymerisation and then top-coated with a specific enteric-soluble polymer which is a hydroxypropyl methyl cellulose acetate succinate or a hydroxypropyl methyl cellulose hexahydrophthalate. The releasability of the active ingredient only in the large intestine can be more reliable when the core medicament form is, prior to coating with chitosan, provided with an enteric undercoating layer.

Title: Transformer connector
Inventor: BARAGAR BERT
IPC: H01F27/40
Filed: 1991-10-25
Abstract: ABSTRACT OF THE DISCLOSURE          A connector for installation between utility transformer secondary leads and service leads.  The connector is for location below a pole-mounted transformer and may be opened or closed from the ground with the use of a tool such as a hot stick.  The connector includes two switches for releasable electrical connection of the secondary and service leads.  Each switch has a rigid immovable member, a movable member and fastener.  The movable member may be brought into contact with and fastened in electrical connection with the rigid member for a closed position of the switch.  The fastener may be released and the movable member moved out of electrical contact with the rigid member for an open position of the switch.  There are two embodiments disclosed.  In the disclosed embodiments, the movable member of each switch includes a flexible cable and the connector includes a spacer between the cables to prevent electical connection therebetween when the switches are open.  The flexible member of each switch has a rigid portion, such as a Z-bar, having an aperture which registers with an aperture in the flexible member.  A bolt fastener is inserted through these apertures and threaded into a threaded hole in the rigid member of the switch for electrical connection of the members.  The bolt has a ring at its end opposite the threaded end and a radial washer axially located between the rigid portion and flexible portion of the flexible member so that the bolt may be screwed in with a hot stick and is not released from the flexible member when its switch is in the open position.  The arrangement is such that the flexible member of a switch abuts an underside of rigid member with which it is paired so that when the swithes are opened, the flexible members are released downwardly to isolate all service leads from the secondary leads, but the flexible members may optionally be biased into an open position.  The second of the two embodiments includes a shroud to hinder bridging contact of switch conductors by small animals.

Abstract: The present invention relates to a silicon nitride sintered body [wherein the composition of Si3N4-first aid (Y2O3 + MgO)-second aid (at least one of Al2O3 and AlN)] falls within a range defined by lines joining points A, B, C and D in FIG. 1, the crystal phase of the sintered body contains both  .alpha.-Si3N4 and B'-sialon, and the relative density is 98% or more.  This sintered body is produced by subjecting a green compact of the above-described source to primary sintering in a nitrogen gas atmosphere at 1300 to 1700°C so that the relative density reaches 96% or more, and the precipitation ratio of the a-Si3N4 crystal phases to the B'-sialon crystal phase in the sintered body is in the range of from 40 : 60 to 80 : 20; and then subjecting the primary sintered body to secondary sintering in a nitrogen gas atmosphere at 1300 to 1700°C so that the relative density reaches 98% or more.  The sintered body has superior strength properties, especially at ordinary temperatures, and can be produced with a high productivity in a high yield at a low cost.

Title: System and method for draining an instruction pipeline
Inventor: BULLIONS ROBERT J III
IPC: G06F9/30
Filed: 1992-02-03
Abstract: SYSTEM AND METHOD FOR DRAINING AN INSTRUCTION PIPELINE                           ABSTRACT      The present invention comprises a system and method for selectively  draining  an  instruction  pipeline.   In  one embodiment, the invention is implemented in the context of pipelined  processor having  an  interpretive  storage  and multiple  execution units.   In  the described  system,  the instructions held in the interpretive storage are referred to as "milli-instructions"  and the interpretive execution mode is referred to as "milli-mode".   Additional hardware controlled    instructions    (private    milli-mode    only instructions) are added to provide control functions or to improve performance.  These private milli-mode instructions augment the architected instruction set. Milli-mode routines can  intermingle  the  milli-mode  only  instructions  with architected instructions to implement complex functions.  In order  to  provide  an  enhanced  level  of  flexibility  and efficiency,   the above-described  embodiment  includes  a milli-instruction that causes the pipeline to drain.  This milli-instruction,  called DRAIN INSTRUCTION PIPELINE (DIP) allows greater selectivity by the coder over (1) when to drain the pipeline and (2) what type of pipeline drain to perform.   In the preferred embodiment,  the DIP instruction enables the coder to cause the system to suspend decoding until   a   selected   event   occurs.    Specifically,   the instruction includes options to suspend decoding until  a selected one  of  the  following  events has occurred:  all conceptually previous macro instructions have completed; all conceptually   previous   milli-code   instructions   have completed;  all  conceptually  previous  instructions  have completed; all store requests have reached the point where no exceptions will occur, but the actual store may not have completed;  all  conceptually  previous  stores  from  all conceptually  previous  units-of-operation  have  completed (serialize); or invalidate instruction buffers and fetch the next sequential macro-instructions.
