Title: Prevention of copper dissolution during cyanidation of gold ores
Inventor: BENNETT CHARLES A
IPC: C22B11/00
Filed: 1989-10-27
Abstract: ABSTRACT OF THE DISCLOSURE          PREVENTION OF COPPER DISSOLUTION DURING CYANIDATION                    OF GOLD ORES          A process for treating copper containing precious metal ores prior to cyanidation and recovery of the precious metal eg gold.  The process involves addition to the ore before or after milling of a water soluble or water dispersible surface active agent in the form of a fatty alkyl amine preferably an ethoxylated fatty alkyl amine.  The agent reduces the high cyanide consumption, which is caused by copper dissolution, by passivating the mineral surface.

Title: Hair treatment apparatus and method
Inventor: GOLAN ZEV
IPC: A45D24/30
Filed: 1989-11-29
Abstract: ABSTRACT         Apparatus  for treating hair including a  handle,  hair separation  apparatus  associated with the handle  and  extending longitudinally along an axis,  apparatus for oscillating the hair separation  apparatus  about  the axis so as to  bring  the  hair separation  apparatus  into repeated engagement with a  group  of hairs  so  as  to  ease  passage  of  the  separation   apparatus therethrough,  and  apparatus for preventing the hair  separation apparatus  from striking a portion of skin to which the hairs are attached.  The hair separation apparatus is oscillated about  the axis axis at a relatively high frequency, of, typically,  greater than  4,000 cycles per minute and preferably greater than  10,000 cycles  per  minute,  and at a relatively  small  amplitude,  of, typically,   no larger than about 5° and,  preferably,  no larger than 2°. A method of delousing hair includes the steps of placing hair separation apparatus in a group of hairs and oscillating the hair  separation apparatus at high frequency,  so as to bring the hair separation apparatus into repeated engagement with the group of hairs in a direction generally transverse to the length of the hairs,  thereby also bringing the hair separation apparatus  into repeated  engagement  with lice and lice eggs located  among  the hairs, so as to cause fatal injury to the lice and lice eggs.

Title: Dispersed systems and method of manufacture
Inventor: FUISZ RICHARD C
IPC: A23L33/20
Filed: 1989-12-12
Abstract: Oleaginous substances such as vegetable oil, baby oil, olive oil, margarine, lanolin, cocoa butter and the like have their affinity for water altered by mixing the oleaginous substance with sugar and melt spinning the mixture in a cotton candy spinning machine or the equivalent. As so modified the product disperses autogenously in water forming a colloidal or colloidal-like dispersion. The modification enables such widely disparate procedures as incorporating shortening oil in a cake mix containing flour but no egg, producing a confection or medicated lozenge by dehydrating the dispersion and allowing the melted residue to solidify.

Title: Sodium sulfur cell for weightless environments
Inventor: ROGERS HOWARD H
IPC: H01M10/39
Filed: 1990-01-05
Abstract: SODIUM SULFUR CELL FOR WEIGHTLESS ENVIRONMENTS                 ABSTRACT OF THE DISCLOSURE          A   sodium  sulfur  electrical  storage  cell includes  means  for  avoiding  bubbles  in the sulfur cathode    during    operation    in    a   weightless environment.   Formation of bubbles of sulfur or other gas  in  the  cathode is prevented by pressurizing the sulfur  cathode  to  a pressure greater than the vapor pressure  of  the sulfur at the operating temperature, typically  about  350  C.    The  applied  pressure is preferably  supplied  by  a chemical compound, such as sodium  azide, that is placed into the chamber holding the  sulfur.    At  the  operating  temperature of the cell,  the  compound  decomposes  to  produce  a  gas, nitrogen  in  the  case  of  the sodium azide, that is substantially  insoluble  in the sulfur yet produces a sufficiently  high  pressure  over  the  liquid sulfur that  bubbles  of gaseous sulfur or other gases cannot form  in  the  sulfur.    If bubbles were permitted to form  in  a weightless environment, they would migrate to  a  location  where  they  would interfere with the operation of the cell.

Title: Process for the production of sodium or potassium l-ascorbate
Inventor: KEGLEVIC TOMISLAV
IPC: C07D307/62
Filed: 1990-06-25
Abstract: ABSTRACT     In the process described for the production of sodium or potassium L-ascorbate, 2-keto-L-gulonic acid monhydrate is esterified with methanol.  The esterification is only partial, that is, is not carried out until the esterification equilibrium is reached.  In an intermediate step, by addition of sodium or potassium bicarbonate in an amount precisely enough for neutralizing the esterified solution, unesterified 2-keto-L-gulonic acid and impurities present are precipitated and separated out.  Then by adding more bicarbonate, the lactonizing of the 2-keto-L-gulonic acid methyl ester formed is made possible.  In order to reach a high yield, the unesterified 2-keto-L-gulonic acid from the bicarbonate precipitation may be re-esterified by the same process, preferably parallel, and also converted into ascorbate. This process makes possible the production of very pure sodium or potassium ascorbate, suitable for pharmaceutical purposes in a profitable way.

Inventor: DE LIMA CASTRO NETTO EDUARDO
IPC: G09F3/03
Filed: 1990-09-28
Abstract: "ABSTRACT Label holders used for closing and sealing bags have the disadvantage of having to be individualized (numbered) since one type of violation would be destroying the label holder to withdraw the security seal intact and then sub-stituting it with a new label holder and re-using the seal.          The label holder of this invention has two protuberances formed with rectangular openings on one portion thereof, which pass through two corresponding openings in the other portion when the label holder is closed.  Two stops, one on each side of the strip of the outer surface between the two corresponding openings are provided.  The security seal has a capsule and a lock interconnected by a thread, which in the sealed configuration are separated by the first protuberance, a part of the lock passing through the opening in such protuberance and a head of the lock being locked within the capsule.  The said part of the lock is connected to the head by weakenings.  A blade projecting from the capsule has a free end which passes through the opening in the other protuberance and is formed with  a lateral projection which engages behind such protuberance.

Filed: 1990-12-20
Abstract: A vehicle which has a foot actuated speed control and linkage, a hand actuated control for selecting the forward or reverse mode, a brake pedal and linkage, and a mechanism connecting the speed control linkage and the mode control. The connecting mechanism comprises a rod coupled to an idler arm of the speed control linkage and a swingable connecting arm.  The arm comes in contact with a selection arm of the mode control linkage to prevent the mode from being shifted when the speed control is depressed, and to limit the speed in reverse.  A stop rod swings down over an arm of the speed control linkage as a parking brake is applied to block the movement of the speed control.
Patent CA-2033484-A1 (CA)
Inventor: WILSON STEVEN R
IPC: D06F39/08
Filed: 1990-12-31
Abstract: A water inlet nozzle is mounted to a clothes washer so that water exiting therefrom during the spray rinse cycle is directed onto a load of clothes which has circumferentially accumulated near the bottom of the wash basket during the drain and spin cycle. The water inlet nozzle has an upper member joined to a lower member which forms a dispersion chamber therebetween. The lower member includes an inclined bottom wall which tends to cause water flowing into the inlet nozzle to disperse laterally. The lower member also includes a cascade portion which is curved downwardly and has a transversely convex crown formed within its radius of curvature which induces some water to flow toward the lateral side walls of the lower member. The upper member has a curved forward wall and a front lip which is angled downwardly and rearwardly. A discharge orifice is formed between the terminal edges of the cascade portion and the front lip which is narrower near its center than it is at its edges. The front lip has a radius of curvature formed therein which is larger near the front lip's center than it is near its edges so that water exiting near the edges of the discharge orifice is directed more rearwardly than the water exiting near the center of the discharge orifice thereby forming an arcuate spray pattern. The edges of the spray pattern are directed higher upon the load of clothes in the wash basket than the center of the spray pattern which assures that the clothes are rinsed as thoroughly as practically possible during the spray rinse cycle.
