Patent CA-2085424-A1 (CA)
Inventor: SUNDBLAD BIRGITTA
IPC: C25B1/22
Filed: 1992-12-15
Abstract: The present  invention relates  to an electrochemical process for the production  of  sulphuric  acid  and alkali metal hydroxide,  from an aqueous anolyte containing alkali metal sulphate.  According  to  the  invention, crystalline alkali metal  sulphate is added to the anolyte, whereby the concentration of water can  be  maintained  below  about 55 percent  by  weight.  In  the  electrolysis, the anolyte is brought to an electrochemical  cell with  a cation exchange membrane. In the cell, sulphuric acid and oxygen are formed in the anode compartment  and  alkali  metal  hydroxide and hydrogen  in  the  cathode  compartment. The steps normally preceding the electrolysis, i.e.  dissolution and purification of  the sulphate can be disposed of, since the process is less sensitive to impurities than  the processes  of the prior art. The present invention also relates to an apparatus for the production of sulphuric  acid and  alkali metal hydroxide according to the invention.

Title: Local application microprocessor based nerve and muscle stimulator
Inventor: KOLEN PAUL T
IPC: A61N1/36
Filed: 1993-03-04
Abstract: ABSTRACT OF THE DISCLOSURE A transcutaneous electroneural stimulation (TENS) device employing microprocessor control of carrier pulse frequency,  modulation  pulse  frequency,  intensity,  and frequency/amplitude modulation factors has been developed. The microprocessor monitors battery status and keypad-entered commands that select the various TENS modalities, and generates the driver signals to produce the output waveform.   The microprocessor is programmed to calculate all stimulation parameters, which are stored in nonvolatile memory  to  provide  concise  and  predictable  programmed functions which can be updated as required.  By selecting a desired program, the system may be programmed for either pain relief or the reduction of edema in the application area.  The output pulse train employs a pulse modulation scheme which  is carrier  frequency tuned  for  location-specific applications by matching the carrier frequency to the electrode/tissue load.  By pulse modulating the high frequency carrier and matching the carrier frequency to the electrode/tissue load, more efficient energy transfer is realized, and the unpleasant burning sensation associated with most TENS stimulation units is virtually eliminated.

Abstract: ABSTRACT      An article for enclosing a bone-in food mass is constituted by a heat shrinkable thin bag and a non-heat shrinkable thick patch bonded to the outer surface of the bag.  The bonding surfaces have high surface energy as the sole bonding means so that, upon heat shrinking, the strength of the patch-bag bond increases, while the bag portion adhered to the patch shrinks to a lesser extent than the remainder of the bag but without the patch delaminating from the bag.  The patch outer surface may be ethylene vinyl acetate, VLDPE, LLDPE or blends thereof.  The inner surface of the patch may be ethylene vinyl acetate, VLDPE and blends of ethylene vinyl acetate and VLDPE.  The bag outer surface may be ethylene vinyl acetate, VLDPE, blends of ethylene vinyl acetate and VLDPE, blends of ethylene vinyl acetate and LLDPE and blends of ethylene vinyl acetate, VLDPE and LLDPE.

IPC: B65G65/44
Filed: 1992-04-27
Abstract: A volumetric dry solids materials feeder comprises a supply hopper (12), a feed trough (26) disposed below the hopper, and an auger (28) disposed in the feed trough (26) to feed out the material. The trough (26) is anchored to a vibration base (32), on which is mounted a vibratory mechanism (56). A vibration transfer spring (36) connects the vibration base (32) to a bracket (38) secured to the hopper (12).   Upon activation, the vibratory mechanism (56) vibrates the vibration base (32) and thus, the trough (26) at a predetermined frequency, while the spring (36) transfers the vibration to the hopper (12). The spring (36) lessens the amplitude of the transferred vibration and changes the frequency thereof, so as to minimize interference (primarily harmonic problems) between the vibration of the hopper (12) and trough (26).

Patent CA-2120570-A1 (CA)
Inventor: BAYER CRAIG E
IPC: F23G7/06
Filed: 1994-04-05
Abstract: A regenerative thermal oxidizer for oxidizing a contaminant in an air or other gas stream includes a heat transfer material which heats the incoming air and collects heat from the exiting air.  The direction of flow of the air through the oxidizer is periodically reverse for the regenerative heat exchange.   When  flow is reversed,  a quantity of untreated air  in the oxidizer which would otherwise be discharged to the atmosphere is collected in a purge chamber which surrounds the lower portion of the discharge stack.  The untreated air enters the bottom of the chamber and the air already in the chamber is forced out from vent holes in the top of the chamber into the stack.  The untreated air in the chamber is fed back to the oxidizer  through  the  inlet  of  the  blower  feeding  the oxidizer while clean air is drawn into the chamber from the stack through the vent holes.

Title: Instrumentation and method for evaluating clot elastic modulus, force development and erythrocyte flexibility during clotting and dissolution
Inventor: CARR MARCUS E JR
IPC: G01N33/49
Filed: 1993-01-15
Abstract: Intermittent application and removal of a compressive force on a blood sample (8) positioned between a pair of plates (12 and 14) throughout clot formation and dissolution provides a standard for using voltage output from a transducer (22) to determine force and elastic modulus parameters. Force development arises from the internal actions of the platelets during clot retraction. Elastic modulus provides a measure of the stiffness of the clot.  Clotting can be measured as an increase in force development and clot elastic modulus. Clot dissolution can be determined by a dramatic decrease in force development and in elastic modulus. Providing the blood sample with a clot dissolving agent such as tPA  allows determining the fibrinolytic potential of whole blood and, thus, aids in identifying patients at risk for thrombosis due to a decreased ability to dissolve clots. Clot elastic modulus provides a measure of erythrocyte flexibility.
