Patent CA-2195883-A1 (CA)
Inventor: BARFUSS JACK E
IPC: F01B3/00
Filed: 1997-01-24
Abstract: This pertains to the invention of the new internal combustion engine  that  consists  of  the  independently operating  internal combustion modules in which the Otto cycle occurs as a result, of interaction of cylinders with pistons that not only reciprocate like  those  in  conventional  reciprocating  engine,  but  also simultaneously  spin around  their common  (and common with the connecting them shaft) symmetry axis.     There is no motion conversion of the reciprocation-to-rotary type as it is in the classical reciprocating engine - the shaft gets its torque straight from the pistons.  The connecting rod, crankshaft, knuckles, counterbalance, and crankcase are eliminated. Pistons and shaft are guided by the unlimited travel bearings which free the pistons from the cylinder guidance.  There is no more contact between piston and cylinder except through the sealing rings located on the side surface of the piston.  The precision oscillating rotary motion of the shaft and piston comes from the oscillating  rotary  bearing  (inventive  on  its  own   -  many applications possible).  Pure rotary motion is recovered by the ball spline bearing that passes  through all  the  linear motion  but engages all the rotary component. The rotary motion is transmitted to  the  rotary  shaft  and  then  outside  to  run  any  possible application.     As a result of the above design elements the torque of the module's  shaft  is  never  equal  zero  as  in  the  case  of  the traditional reciprocating engine whenever its pistons are in either of the extreme positions. The pistons neither slap against the cylinder walls nor rub against them. Much less energy is expected to be dissipated by the new engine. Much less vibration and heat generated, much cleaner, more efficient operation is anticipated.

Abstract: A system and method in accordance with a preferred embodiment enable objects from two or more heterogeneous object systems in a digital computer to interoperate and be combined in the creation of a larger object-oriented software project, as well as uses of such system and method. Objects from a foreign object system are unmodified, yet appear to be native to the object system in which they are used or accessed. A native proxy object (indistinguishable from other native objects) is constructed for the real foreign object. The proxy object contains an identifier to the real object, as well as a pointer to a software description of how to access and manipulate the object - e.g. how to call its methods, set its properties, and handle exceptions. When the proxy object is manipulated, it follows the instructions in the software description which, in turn, results in the corresponding manipulation of the foreign object.

Patent CA-2201082-A1 (CA)
Inventor: LIANG CHUNG C
IPC: H04L12/56
Filed: 1997-03-26
Abstract: The invention routes SVC ATM call setups by utilizing one of a plurality of designated transit lists (DTLs) stored at an originating node. The DTLs describe all routes in the network from the originating node to endpoint destinations. When a call setup message is received at the originating node, it inserts a desired DTL as an information element (IE) of the setup message.      Each DTL is formatted as a concatenation of elements with each element including the node ID and output ports of each successive node in the route. Preferably, each element of the DTL includes flags such as a "process" flag which indicates whether an element of the DTL has been processed by a node, a "link up" flag which indicates that an alternative route is available between two nodes should the preferred route be down, a "bandwidth" flag which allows the alternate link to be used if the preferred link is busy, and a "last node" flag which is used in the last element of the concatenated DTL. If the "last node" flag is not set, the destination node internally generates a route ID as the last element based on the destination address specified in an IE for the call. As the DTL IE is passed from node to node along the connection path, the receiving node inserts the input port at which it received the call setup message as well as a VPI/VCI into its element of the DTL. At its destination, the DTL is attached to a CONNECT request message which is returned to the source node.
