Patent CA-2095277-A1 (CA)
Title: Method for the production of detergent builder formulations utilizing spray granulated citric acid and salts thereof
Inventor: MOTHES HELMUT A
IPC: C07C51/43
Filed: 1993-04-30
Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed are compositions of particulate citric acid or an alkali metal or alkaline earth metal salt thereof prepared by an improved method and an improved method of preparing a detergent builder composition.  The method of preparing particulate citric acid or salts thereof involves spray granulating citric acid or a salt thereof from its partially purified fermentation broth to form granules which are freer flowing and less inclined to fracture than is citric acid or its salts prepared by crystallization techniques which properties render the material prepared by the present method suitable for handling in bulk.  The same properties may be imparted to detergent builder compositions by adding detergent builders to the partially purified fermentation broth or by introducing a detergent builder solution into a fluidized bed reactor together with appropriate seed particles to thereby form granules which include such detergent builders. This method may be used advantageously to prepare the detergent builder, tartaric monosuccinate/tartaric disuccinate which is particularly difficult to crystallize, in a dry granular form.

Patent CA-2097540-A1 (CA)
Inventor: ARJOMANDI ESHRAT
IPC: G06F12/02
Filed: 1993-06-01
Abstract: A mechanism and method for accessing remote data objects in a  distributed  memory  environment  is  disclosed.   In  the distributed  memory  environment,   a  number  of  parallel processors are remote from each other and each has memory storage capacity with parallel address locations.  For each data object stored in the local memory of a processor, that processor stores a variable at a specific location pointing to the address of the data object in its local memory.  At the same (parallel) location in the local memories of all remote parallel processors, a variable pointing to the home processor for the data object is stored.  In order to access the  data  object,  it  is  only  necessary  to  locate  the identifier variable in the processor processing a program pointing to the processor having the data object in storage. Because of the parallel address space,  the location will automatically point directly to the same address location in the  home  storage  processor,  and  this  address  location contains the address pointing to the actual location of the data  object  in  the  local  storage  of  that  processor. Alternate means for updating the variable information on data  object  storage  is  also  provided.   In  one  system, changes  are  broadcast  throughout  the  parallel  processor environment while in the other system,  changes are merely retained on the home processor or the home processor and one remote parallel processor responsible for recording changes in that region of the distributed memory environment.  When accessed by another remote parallel processor,  the change information will be transmitted.

Title: Methods of Producing Caustic Soda Without Chlorine
Inventor: PLETCHER DEREK
IPC: C25B1/16
Filed: 1993-02-05
Abstract: Methods for the electrolysis of aqueous solutions of alkali metal carbonates and bicarbonates for the production of alkali metal hydroxides at current efficiencies of > 85 percent without the simultaneous co-production of halogen or acid can be performed at very low, commercially attractive cell voltages and at high current densities in single or two solution compartment cells with carbon dioxide as the only substantive co-product by maintaining cell pH at > 7. The methods are also especially suitable for retrofitting existing chlor-alkali facilities for shifting the balance of production in favor of caustic soda at peak demands. The methods may also be performed with fuel cell configurations for even more attractive operating economics. The electrochemical cell (10) has a cell divider (22); a hydrogen consuming anode (14); a caustic producing multi-dimensional cathode (16); and appropriate inlets (28, 30, 38) and outlets (41, 40, 32, 34).

Title: Multimedia digital foil presentation system
Inventor: CRONE JOANNE E
IPC: G06F3/0481
Filed: 1994-08-12
Abstract: A navigation means for permitting a presenter to randomly access digitized foils with minimal audience distraction.  The navigator includes an on-screen indicator with several fields in a narrow band format that identifies the specific digital foil currently displayed on a presentation medium and also identifies the other digitized foils in the same unit.   Using a selector, such as a pointer or keystroke, the presenter can select any other digitized foil within the same unit to replace the current display.  To move outside  of  a  specific  unit,  the  presenter  simply  selects  a different unit in the same or a different section within the same module or a different module by selecting other fields displayed on the  indicator,  again by using a pointer or  keystroke.   The indicator itself may be hidden from view when not in use, and when in use, may be the same background colour as the displayed foil or even be entirely blocked from the audience's view to minimize audience distraction.

Title: Rate responsive cardiac pacemaker
Inventor: OLIVE ARTHUR L
IPC: A61N1/365
Filed: 1994-09-27
Abstract: A cardiac pacemaker having an automatic pulse rate response gain factor responsive to at least one cardiac-related physiological characteristic of, a patient. The pacemaker includes a rate controller that comprises a detector nor detecting a plurality of individual measurements of at least one physiological characteristic over each of a plurality of pre-determined time periods, with each of the individual measurements being an average of values detected over each of a respective multiple number of incremental time periods occurring within each of the pre-determined time periods. The pacemaker saves the highest measurement from one incremental time period of each of several consecutive pre-determined time periods, and these highest measurements are averaged. Thereafter, the rate controller adjusts the rate response gain factor or slope of the pulse rate in relation to the physiological characteristic measurement and a pre-determined target pulse rate. In a preferred embodiment, two physiological characteristics are measured, with high values averaged of only one characteristic when that characteristic exceeds a threshold level of the other characteristic. One embodiment is pulse rate responsive to minute volume measurement in combination with accelerometer measurement, with accelerometer measurement requiring a threshold value over an increment of time prior to minute volume recordation for input toward rate response gain factor.
