Title: Methods of enhancing wound healing and tissue repair
Inventor: BOCKMAN RICHARD
IPC: A61K33/24
Filed: 1990-11-13
Granted: 2002-02-12
Abstract: Skin, connective and support tissue repair is enhanced and augmented by administering pharmaceutically acceptable galli-um-containing compounds in amounts sufficient to provide therapeutic levels of elemental gallium. Gallium-containing com-pounds mimic the effects of endogenous growth factors to induce cells within these tissues to produce new matrix by increasing the formation of critical structural matrix proteins responsible for skin, support and connective tissue repair, maintenance and augmentation. Gallium-containing coumpounds are suitable for a variety of applications in wound healing, including dermato-logic and cosmetic skin repair, bone fracture repair and successful bonding of implanted tissue grafts and connective and support tissue prostheses. The unique ability of the gallium-containing compounds to increase new matrix component formation and fa-vorably alter the proliferation of specific cell types needed for tissue repair is separate and distinct from gallium's inhibitory ae-tivity on matrix-resorbing cells such as bone-resorbing osteoclasts.

Patent CA-2078740-C (CA)
Title: Generation of horizontal sync pulse
Inventor: COLLES JOSEPH H
IPC: H04N5/10
Filed: 1992-09-21
Granted: 1999-12-14
Abstract: A system eliminates the adverse effects of serration and equalization pulses (periodically generated during the vertical sync interval) in regulating the frequency of horizontal sync pulses. These sync pulses provide timing information to regulate a video display. The system includes circuitry for stripping and processing the horizontal and vertical sync signals and the serration pulses from the video signals. These pulses are introduced to a first AND gate and through a first delay line to an input of a second AND gate.      Frequency divider output signals are introduced to the first AND gate and to a third AND gate through a second delay line having an equal delay with the first delay line. The output from the first AND gate passes to second inputs of the second and third AND gates. The second and third AND gates produce signals which represent the time difference between the sync and divider output signals and which have a maximum time difference equal to the delays of the delay lines. In doing so, the gates eliminate the effects of the serration and equalization pulses. A phase comparator compares the times of occurrence of the second and third AND gate signals and introduces to a low pass filter the signals representing the time difference. A voltage controlled oscillator produces a signal having a frequency dependent upon the magnitude of the output voltage from the filter. The frequency of the oscillator signals is passed to a frequency divider. The resultant divider signals are introduced to the first AND gate and the second delay line.

IPC: D21C11/02
Filed: 1993-11-29
Granted: 2006-01-31
Abstract: When producing green liquor for later manufacture of cooking liquor, it is endeavoured that the green liquor shall be readily clarified and/or readily filtered. This endeavour is achieved with the present invention, which relates to a method of producing green liquor in which waste liquor separated from cellulose pulp and derived from a cooking stage and possibly from one or more bleaching stages is worked up including known treatment stages such as evaporation, combustion, smelt dissolving and other green liquor preparation, and in which a calcium containing chemical is added to the waste liquor prior to combustion, or is added at the combustion of the waste liquor. The method is characterized in that carbon deriving from the smelt is caused to equal at most 0.3 weight promillage, calculated on the smelt after combustion, when and after dissolving the smelt in liquid; and in that the addition of calcium is controlled so that the amount of calcium added together with the amount of calcium that is already present will equal at least 3/4 of the amount of magnesium present in the waste liquour calculated in mol; and in that the addition is at most 10 % by weight of the sodium plus sulphur present in the waste liquor.
