Abstract: This  invention  relates  to  a  novel  submerged combustion system.    More  particularly,  this  invention relates to a novel submerged combustion system which can be installed singly or in combination with other  similar submerged combustion systems to heat large quantities of liquids and solutions.   The invention is directed to a method of  regulating hydrostatic pressure in a  liquid through which hot gas is being passed, and the liquid is heated by heat from the hot gas, comprising:  (a) means for sensing temperature of the hot gas after it is passed through the liquid;  (b) means for sensing the temperature of the liquid after it has been heated by the hot gas; (c) computer means programmed for comparing the temperature of the hot gas and the temperature of the hot liquid;  (d) means  for  adjusting  the  distance  the  hot  gas  travels through the hot liquid, said means being regulated by said computer means.   A novel feature of this invention is a method and apparatus for cooling the combustion chamber of a submerged combustion system.   The cooling system com-prises a cooling fluid means located at the upper region of the  combustion  chamber,  the  combustion  chamber  which extends above the level of the liquid in the tank means being cooled by a cooling fluid which is introduced into the cooling fluid means, and spills over the top edges of the combustion chamber and runs down the outer walls of the combustion chamber until the cooling fluid reaches the surface level of the liquid being heated by the hot gaseous combustion product.  Another novel feature of this inven-tion is a method and apparatus for minimizing turbulence in the submerged combustion system.   In the method, the hot gas is exhausted from the combustion chamber through ports of a size predetermined to minimize foam being created at the liquid surface.

Inventor: FRIESE PETER E
IPC: A61M5/50
Filed: 1996-01-26
Abstract: A disposable auto-destruct syringe is disclosed which includes a syringe barrel for holding an injectable fluid, a piston reciprocatable in the barrel and sealingly engaging the barrel wall, a plunger having a forward portion normally positioned in the barrel and a rearward portion to be manipulated by a user of the syringe, a coupling mechanism for connecting the piston with the plunger to permit axial movement of the piston in the barrel by operation of the plunger, and a deforming structure for permanently deforming the barrel wall to brake the seal between the piston and the barrel wall. The deforming structure is in the form of cutters or burrowing elements mounted by way of elastic arms to one of the piston and the plunger. The deforming structure is movable from an at rest position wherein the barrel wall is not deformed, to a barrel wall engaging position wherein the barrel wall is permanently deformed by the deforming structure. The syringe further includes an engaging mechanism for forcing the deforming structure into the barrel wall engaging position upon rearward movement of the piston after a full or partial injection stroke only. The engaging mechanism is mounted to the other of the piston and plunger. This construction provides for an auto-destruct syringe wherein the barrel wall is permanently deformed not during the injection stroke, but only when refilling of the syringe is attempted after a full or partial injection stroke so that the auto-destruction action does no longer interfere with the injection stroke.

Patent CA-2179249-A1 (CA)
Inventor: VOKEY DAVID E
IPC: G01R31/08
Filed: 1996-06-17
Abstract: A resistive fault location method and apparatus are used on communication and power cables. Two instruments are connected to opposite ends of the faulted conductor. Each takes a series of voltage and current measurements that are then processed to determine the distance from each end of the conductor to the fault. To eliminate voltage and current transients, the data collected is statistically analyzed and data that is analyzed as being affected by transients is discarded. The remaining data is taken as being steady state data. This eliminates any requirement for simultaneous measurements at opposite ends of the conductor and accounts for any situation where local transients at the two ends of the conductor are different at any given instant.

Patent CA-2179856-A1 (CA)
Inventor: LUCIANI SABATINO
IPC: H02K15/12
Filed: 1996-06-25
Abstract: A system for applying a controlled amount of resin to the coils of armatures on an armature manufacturing line is provided.  The system operates without costly piston displacement pumps by metering the resin according to weight instead of volume.  A reservoir of resin is maintained on a scale which supplies an electronic weight signal to a system controller.  When resin is not being applied, the system uses the weight measurement to control the refilling of the reservoir.  When resin is being applied, the system monitors the weight of the reservoir, stopping the dispensing of resin when the weight of the reservoir has decreased by the weight of resin to be applied.  The same system can be used to adjust the flow rates of individual valves or dispensers, by measuring the weight dispensed through a single valve or dispenser during an interval of predetermined duration, and adjusting the valve or dispenser until the desired weight is dispensed during the predetermined duration.

Patent CA-2197328-A1 (CA)
Title: Optoelectronic coupler
Inventor: BROWN THOMAS G
IPC: G02B6/12
Filed: 1995-08-14
Abstract: The invention is an optoelectronic device for coupling between an external optical wave (10) and a local optical wave (16, 18, 20). The local wave is supported by a multiplicity of electrodes (12), and a structure associated with the electrodes. The multiplicity of electrodes are spaced in a substantially regular pattern and are adapted for two functions. First, the electrodes resonantly couple between the external wave and the local wave. Second, the electrodes allow a potential difference between adjacent electrodes. In one embodiment, the multiplicity of electrodes are substantially planar, metal, interdigitated electrodes including first finger and second fingers (22, 24). The electrodes are further adapted to allow a potential difference between the first fingers and the second fingers. In addition, the structure associated with the electrodes is a substantially planar silicon substrate (14) contacting the electrodes. The local wave is a surface plasmon (16) supported by the metal electrodes and silicon substrate. The index of refraction of the silicon may be altered by varying the potential difference across the first and second fingers of the electrodes. The optoelectronic coupler may be configured to modulate or detect incident light.
