Patent CA-2297938-A1 (CA)
Inventor: DURHAM ROSALIE JOYCE
IPC: A23L33/00
Filed: 1998-07-24
Abstract: A separation process for isolation and purification of useful nutrients from food process streams is described. The process includes the steps of contacting an aqueous solution including a nutrient and divalent ions with an ion exchange resin including monovalent ions. The eluate which is depleted of divalent ions is collected and subjected to a process capable of separating monovalent ions to obtain a permeate fraction including monovalent ions and a retentate fraction including said nutrient. The retentate is separated into fractions, wherein at least one of said fractions includes the major portion of said nutrient, which may then be further purified.  The ion-exchange resin can be regenerated by contacting the ion-exchange resin with a solution including the permeate fraction until a major portion of divalent ions in the ion exchange resin have been replaced by monovalent ions.
Patent CA-2301362-A1 (CA)
Inventor: COX JAMES STACY
IPC: A01K1/01
Filed: 2000-03-20
Abstract: The invention includes a litter box with an associated cleaning assembly that may utilize a bag and a box frame that may include a storage area for the assembly. The litter box has a rectangular frame with an open top and a floor separated by four integral walls. The cleaning assembly includes two rakes that each have a handle with several spaced apart teeth. Each tooth has an end and a tip. During use, the rakes slide across the box top while engaging the litter disposed therein. The teeth are inserted into the litter at each end of the box against the slanted end walls of the box by pressing the tips into the litter mass adjacent thereto. Then the rake ends are pushed inwardly until they reach the floor. The rakes then slide forwardly until the rake handle rests on top of the box frame. The rakes are then pushed simultaneously toward each other until reaching the box center while the debris in the litter is collected and pushed forward by the rake teeth while clean litter flows through gaps between the teeth. The rake teeth are horizontally spaced to permit the rakes to interlock when they meet to form a V-shaped chamber that captures the collected debris with a combined handle and a shield. When the interlocked rakes are lifted upwardly, all remaining clean litter falls free through the teeth while the chamber retains the collected debris. A barrier at one end of the chamber prevents debris from exiting while the other end forms an open waste removal port. The debris exits the chamber from the port when the obstructed end is tilted upwardly. The cleaning assembly may include a coupling for temporarily securing a bag to the port.  After emptying the chamber, the rakes are separated, cleaned and stored. The base of the litter box may include an area for storing the rakes.
