Patent CA-1280499-C (CA)
Inventor: AVERY RANDALL N
IPC: F28F1/10
Filed: 1987-07-02
Granted: 1991-02-19
Abstract: ABSTRACT OF THE DISCLOSURE           A heat exchanger panel suitable for cooling fluid filled electrical apparatus,  such as electrical distribu-tion and power transformers,  and method of constructing same,  which  withstands  substantially  higher  pressures without adding significantly to  the weight of the heat exchanger.  The metallic sheet which is used to construct the heat exchanger panel  includes  edges which define  a substantially rectangular configuration, with predetermined opposite edges thereof being folded to increase the edge thickness of the sheet prior to forming the fins.  The fins are formed via bend lines which extend from folded edge to folded edge.  This provides at least twice the material thickness where the heat exchanger panel is welded to the tank of the associated apparatus, and at least four times the material thickness where the folded fin is welded to form the fin cavity.

Abstract: "HEAT EXCHANGER"          ABSTRACT OF THE DISCLOSURE     A heat exchanger includes a core structure formed by a plurality of plate members in stacked arrangement.  Each plate member is square or rectangular and includes along two opposed sides a portion bent at right angles to the basic plate and then bent inwardly to wrap around the next adjustment plate member.   The other two sides of the plate member are bent in the opposite direction and then turn inwardly to act as  spacers  to  hold each plate member from the next by a predetermined  dimension  thus  defining  cells  between  each plate member and the next adjacent plate member.  This core construction is then assembled  in a plurality of separate core members into a frame structure defined by a pair of side frames defining rails along which the core members can slide.

Abstract: ABSTRACT             A missile having a super-calibre control-surface system, the fins of which are folded into the missile structure for storage, for transportation, and for launch, when they are locked in this position at the face end, until they are released by a safety system as a function of launch acceleration, when they deploy, is fitted with a compact, functional safety system that releases all the fins simultaneously, but not prematurely, so that they may deploy.  To this end, there is a plunger that acts simul-taneously in all the fins and which can be displaced axially in the direction of launch relative to these; this plunger only moves into the release position when the missile launch acceleration has diminished.  Prior to this, in the opposing direction of displace-ment, a safety pin is sheared by the plunger or a separate shearing sleeve, said safety pin locking the plunger in the locked position during logistic handling of the missile.

Title: Vault cartridge mechanical, data and power coupling system
Inventor: TALMADGE PAUL C
IPC: G06K7/08
Filed: 1988-10-03
Granted: 1993-04-06
Abstract: ABSTRACT OF THE DISCLOSURE            An electromechanical vault cartridge receptacle has an opening for inserting a vault cartridge, the cartridge passing between a pair  of laterally biased  rollers which  continuously  engage  asymmetrically  contoured sided surfaces of the cartridge.  A front surface edge of the cartridge bears upon and causes the backwards motion of a movable frame, the motion of which causes top and bottom surfaces of the cartridge to be securely engaged between an opposed pair of horizontally planar cartridge  bearing  members.    The  bearing  members comprise conductive plate means which are brought into registration with corresponding plate means beneath top and  bottom  surfaces  of  the  cartridge  for  defining signal coupling capacitors.  The backwards motion of the movable frame also results in roller supporting members  to  be  locked  when  the  cartridge  is  fully inserted,  thereby preventing lateral movement of the rollers.    A   cartridge   ejecting   means   comprises electromechanical means adapted  for engaging a back surface of the movable frame to move the movable frame in  a  forwards  direction,  disengaging  the  cartridge engaging members and unlocking the roller supporting members, whereby the cartridge is pushed back out of the opening.   The receptacle also comprises tapered cartridge stop means which is  a primary portion of a power  transformer  which  is  adapted  for  physically contacting  a  secondary  portion  disposed within  the cartridge for providing the cartridge with operating power.

Title: Method of multicast message distribution
Inventor: PERLMAN RADIA
IPC: H04Q3/00
Filed: 1989-07-05
Granted: 1993-06-08
Abstract: ABSTRACT OF THE INVENTION         A method for multicast communication wherein a multicast message is distributed to all the nodes in a multicast range.  If a multicast message has a multicast range which is larger than one link in the network then the message is forwarded along a unique set of pathways through the range.  The unique set of pathways is called a multicast spanning tree and is unique to all nodes which can communicate directly by virtue of a list of known nodes.  The network is divided into areas each of which contains a group of directly communicating nodes.  A group of nodes designated as level two nodes facilitates communication between the nodes in different areas.

Abstract: ABSTRACT       The bandage for maintaining the anterior chamber of an eye according to the present invention is formed so as to cover an incision during operation and to tightly contact with the incision and its circumference, has a small hole for insertion of instruments for operation and is transparent.  This bandage can prevent the outflow of aqueous humor through an incision during ocular operation without conducting the temporary suture of incision and thereby enables ocular operation in a state where the anterior chamber is maintained.  Therefore, the bandage has solved various problems (e.g. complicated operation procedure, long operation time, high invasion associated with operation) encountered in the conventional ocular operation wherein the incision is temporarily sutured to prevent the outflow of aqueous humor therethrough and thereby to maintain the anterior chamber.
