Patent CA-2084228-A1 (CA)
Inventor: PIESIK EDWARD T
IPC: F41A13/00
Filed: 1992-12-01
Abstract: A convoluted fan structure is provided along the bottom surface of each diagonal segment of a petal-formed aft cover for a missile canister. As the cover petals open under influence of rocket exhaust impingement on the cover, the fan structures cover the diagonal areas toward the corners of the opening.   This prevents recirculation of rocket exhaust gases from the plenum into the canister through the formerly open corner areas and augment the closure force to restore the petals to the closed position after completion of missile launch.
Patent CA-2084705-A1 (CA)
Title: Single-use hypodermic syringe with retractable needle
Inventor: KLEIN EDWIN N
IPC: A61M5/145
Filed: 1992-12-07
Abstract: ABSTRACT OF THE DISCLOSURE    A hypodermic syringe includes a hollow barrel in which a piston is slidably disposed.  The piston is detachably connected to a plunger which extends through one end of the barrel.  A syringe floor member is temporarily anchored to the barrel at its other end, as by an O-ring which is attached to the syringe floor and which extends into a groove in the barrel.  A needle assembly can be mounted on the syringe floor member.  The syringe floor member has a latching flange which grips the piston after an injection has been administered.  The plunger then can be pulled rearward to retract the floor member and attached needle assembly into the barrel, with the plunger then being disconnected.  This prevents accidental needle sticks which might spread com-municable diseases among health care professionals or their patients.  Furthermore, the piston remains permanently latched to the syringe floor member so that fluid can no longer be drawn into the syringe.  This feature prevents reuse of the syringe in the event that it is not disposed of properly and is later found by an intravenous drug user or other authorized person.

Title: Retrievable Well Packer
Inventor: HENDRICKSON JAMES D
IPC: E21B33/128
Filed: 1993-05-12
Abstract: A retrievable packer for service at high temperatures and pressures has sealing provided by a seal element prop surface (56) of larger diameter than the seal element support surface (48) of a body mandrel (34).  At least one element (30A) of a seal assembly (30) is supported on the prop surface and is subjected to a radial squeeze in the set configuration, even though a lowermost seal element (30C) may be subject to longitudinal separation.  The split level support arrangement provides an annular pocket (62) into which the elements can be retracted upon release of the packer, thereby providing clearance for retrieval.  In releasing the packer, a retainer collar (68) is shifted away from a metal backup shoe (64), thereby providing an annular pocket into which the shoe is deflected, so that it does not obstruct the drift clearance during retrieval.  The seal element assembly is preloaded by a cover sleeve (50) which releases when a predetermined compression has been achieved.  The controlled preloading of the seal elements assists movement of the elements to the larger diameter prop surface, and the seal elements are forced to expand into the annulus uniformly to prevent the formation of uneven extrusion gaps.

Title: Actuating device for a sliding gate valve on a vessel containing metal melt
Inventor: ELLEND WALTER
IPC: B22D41/38
Filed: 1993-07-14
Abstract: ABSTRACT            The  actuating device  (20)  serves,  in particular,  to actuate a sliding gate valve  (15)  on a metallurgical vessel   (10)   in   which   the   actuator,   which   is conventionally  constructed  as  a piston/cylinder unit (24), is laterally arranged on the vessel (10) for space reasons.   This actuating device (20) has a deflecting element (22) which is rotatably mounted on the vessel (10)  and which  connects  the  drive  rod  (24)  of  the piston/cylinder unit (24) with that of the sliding gate valve  (15).   Provided for the drive rod  (21)  of the sliding gate valve (15) is a guide element (30) which engages approximately at its end and with which this drive  rod  (21)  is  held  over  the  entire  stroke. Preferably  this   guide   element   (30)   is   secured independently of the sliding gate valve to the vessel (10) and has a steering arm (31) and a connecting arm (32), the steering arm (31) being rotatably mounted on the one hand on the end of the drive rod and on the other hand  on the  connecting  arm  (32)  and the  latter  is pivotally mounted on the vessel  (10).   The transverse forces acting from the actuator on the drive rod (21) of the sliding gate valve are thus optimally accommodated and operational disruptions,  which led previously to bearing wear in bearings provided in sliding gate valve housings, may be completely eliminated.
