Title: Machine and method for measuring skeletal misalignments in the human body
Inventor: BENESH PETER
IPC: A61B5/103
Filed: 1990-10-26
Granted: 1995-07-18
Abstract: The machine of the present invention measures and records in terms of the orientation planes of motion the presence of, the location, of and the severity of the postural distortion-stress effects of C-1 subluxations on the human body, making possible thereby   statistical   analyses  between  C-1  misalignments (determined by X-ray analysis)  and such postural distortion-stress effects on the skeletal framework as directly result from the misalignment interferences of C-1 on the nervous system and its  normal  functioning.   This machine  can demonstrate the postural distortion-stress effects of C-1 subluxation on the spine by checking the malpositional  relationships of upper thoracic vertebral segments and pelbis prior to and subsequent to C-1 correction, indicating thereby the corrections obtainable throughout the spine and thus reducing the need for repeated applications of X-radiation to the patient.   The machine has movable elements which provide indications of corrections or displacement and has a pair of weight sensitive platforms with horizontally adjustable pads (foot guides).  The platforms are coupled to force transducers which indicate a means for measuring the portion of total body weight that is supported by each of the patient's feet.   The pads are individually or simultaneously adjustable toward and away from each other to properly spaced the feet relative to the ilii.
Patent CA-2033253-C (CA)
Title: Phase adjustable metering pump, and method of adjusting the flow rate thereof
Inventor: PINKERTON DENNIS
IPC: F04B49/00
Filed: 1990-12-27
Granted: 1995-05-23
Abstract: A valveless, positive displacement metering pump is provided by the invention.  Such a pump includes a housing, a working chamber within the housing, a piston within the working chamber, the piston including a duct defined by a portion of its outer surface, one or more inflow ports communicating with the working chamber, one or more outflow ports communicating with the working chamber, and a drive cylinder for simultaneously rotating the piston and causing it to move in back and forth strokes within the working chamber.  The housing is rotatable with respect to the piston to adjust the timing of the fluid communication between the duct and the inflow and outflow ports, respectively.  Such adjustments in timing allow the flow rate of the pump to be fine tuned, and allow each port to experience a partial suction as well as a partial discharge.          It also allows backflow to occur in an inflow line to the pump, thereby cleaning any filters within the inflow line or agitating a suspension from which the inflow line draws fluid.          It also permits suction to be applied to an outflow line at the end of a discharge stroke, thereby preventing hanging drops or strings from forming at the discharge end of the outflow line.          In addition, timing adjustment allows the manufacture of relatively inexpensive pumps in which the axes of the drive cylinder and working chamber are maintained in fixed positions relative to each other.  A method for adjusting the flow rate of a valveless, positive displacement metering pump is also provided which includes adjusting the phases at which the piston duct communicates with each of the ports of the pump.

Title: General kernel function for electronic halftone generation
Inventor: RYLANDER RICHARD L
IPC: G06T5/00
Filed: 1991-09-13
Granted: 2002-01-01
Abstract: There is disclosed an algorithm for use with a digitized image which provides a means of simulating a continuous tone image containing a range of gray shades from black to white or a color separation. The "threshold equation" is the key of the invention as it calculates a threshold gray value that is compared to the desired local image value to determine whether that particular point should be "on" or "off". Which points (spots) are "on" and which are "off" is determined by the function that assigns a "threshold" value (the shade at which a pixel changes from "off" to "on") based on a pixels "x" and "y" coordinates.

Title: Recovery of gold and silver from complex refractory sulphide ores by cyanidisation and oxidation with peroxides
Inventor: SMITH TREVOR JOHN
IPC: C22B3/14
Filed: 1990-04-27
Granted: 1997-12-30
Abstract: The recovery of noble metals by sodium cyanide leaching from complex refractory gold and silver bearing ores containing such complex silver sulphides as polybasite, pearcite, pyrargyrite, tetrahedrite and argentite presents difficulties in that the precious metal is trapped inside the refractory matrix of the mineral. Pretreatments such as roasting, acid pressure leaching and biological leaching are capital intensive and to obviate this disadvantage, the use of an alkali/alkaline earth metal peroxide is applied as an additive, in an amount ranging from 0.1 to 5.0 kg/t. Preference is for calcium peroxide, which is more stable, consumes less cyanide, is simple to use and monitor, and enhances the process and recovery by improvement in leach kinetics.
