Inventor: KALLIOINEN JOUKO
IPC: B03D1/14
Filed: 1997-04-30
Abstract: A method for extracting floatable minerals from a slurry (3). Slurry (3) is fed into a tank (2) via a feed inlet (25) and agitated and aerated so as to create an upper zone containing froth enriched with the floatable minerals.

Title: On-demand fast cycle mold
Inventor: WU JONG LIANG
IPC: B29C45/72
Filed: 1997-09-18
Abstract: An on-demand fast cycle mold for producing injection molded products such as polypropylene blister package bases. The on-demand fast cycle mold has a heated and cooled hot runner system which provides a short response time and optimal temperature control. On-demand injection molding is made possible by a pulse modulated closed loop mold cooling system, the cooling design of brazed gate inserts, and an effective layout of the cooling channels. The programming of the software for a computer control system has also been designed to achieve on-demand injection molding. The design of the closed loop mold cooling system incorporates an advanced cooling circuit layout, and provides for easy maintenance and better quality control of the coolant which significantly reduces corrosion and scale buildup.      Mold cooling is controlled by sensors installed inside the mold which are used in feedback control loops.      The brazed gate inserts provide precise mold temperature control and improved cosmetic appearance of the molded packages. The use of a needle-valve injection nozzle results in reduced cycle time and improved moldability.

Title: Automatic sheet dispensing mechanism for hand-fed patty machine
Inventor: DAVIS RONALD R
IPC: B65B25/08
Filed: 1997-05-12
Abstract: A sheet dispensing mechanism employs an open bottom sheet dispenser (44) positioned beside a molding device (14), molding articles (34) which are cyclically ejected and driven vertically downwardly along an article ejection path (T), with the bottom sheet (40) shingling out against an oblique baffle (112A). A pair of rotatable indexing rollers (88) with a high coefficient friction member (89) on the periphery of each roller penetrate the open bottom of the dispenser to press the single sheets against the baffle, thereby allowing the indexing rollers to frictionally drive only the end sheet in the direction of the path. A spring biased articulated nip roller assembly (99) downstream of the dispenser accelerates the indexed sheet to intersect the ejection path of the article simultaneously with ejection of the article. A proximity switch senses the arrival of the food portion at the article ejection station to initiate one cycle rotation of the indexing rollers to index the bottom-most sheet of the stack.
Patent CA-2226585-A1 (CA)
Inventor: MARCON ROBERT VICTOR
IPC: A23G4/12
Filed: 1998-03-16
Abstract: A chewing gum composition which can help reduce dental decay, and dentinal hypersensitivity.  To achieve these results the  consumer  begins  by  masticating  this  new  chewing  gum composition in order to produce excess saliva.  This operation loosens much of the food particles left in the mouth and permits them to be easily swallowed.  Many of these particles are also assimilated into the chewing gum composition and so removed as harmful agents.   Excess saliva will also begin to dilute the acids produced by dental plaques but by employing, into the chewing gum composition, one or more water soluble alkaline compounds significantly more will be neutralized.  Moreover, a chewing gum composition containing sodium bicarbonate or other abrading agent and or a peroxide based compound will gently scrub teeth and so help minimize the accumulation of bacterial plaques.   Sodium bicarbonate also has the ability to absorb odours and, therefore, the effects of halitosis can be reduced by its use.  Odours are not just masked but are absorbed, thus, providing a much more effective solution than that of odour masking.   Masticating a chewing gum composition containing a peroxide based compound will release significant amounts of oxygen thereby lessening the quantity of oral plaques.  In turn, the unpleasant odours sporadically exhibited by these plaques will be reduced also. Finally, the further incorporation of a fluoride based compound and or a dental desensitizing agent will notably reduce dental decay and or dentinal hypersensitivity, respectively.  This product, therefore, provides an effective, convenient, inexpensive, and safe solution in helping reduce dental plaques, oral odours, and dentinal hypersensitivity.

Abstract: There are disclosed improved water-soluble metal working fluids comprising polyaspartic acid, amides and salts thereof, a corrosion inhibitor(s) and a basic additive said additive having sufficient basicity and buffering power to maintain the pH of the composition above about 8.5 and preferably above about 9. Such compositions are useful as lubricants in processes to cut, bend, grind and shape both ferrous and non-ferrous metals and tend to maintain higher pH  values due to the incorporation of a basic additive. The polyaspartic acid and salts thereof are particularly advantageous in that the fluids can be easily disposed of after use without special treatment because polyaspartic acid and salts thereof are readily biodegradable.
