Title: Stabilized sweetener composition
Inventor: CHERUKURI SUBRAMAN R
IPC: A23L27/00
Filed: 1991-05-23
Abstract: Abstract A stabilized dipeptide sweetening composition useful in chewing gum applications provides longer shelf life stability and improved longer lasting sweetness.  A dipeptide sweetner such as aspartame is encapsulated through an anhydrous process that compresses the crystals within a mixture of inert binder ingredients so as to form a solid tablet or sheet which is then ground into fine granular particles.  These particles may then be coated with a hydrophobic material such as a fat or wax and then incorporated into a variety of food applications such as chewing gum.  The sweetener composition is thereby protected from adverse environmental conditions such as high temperature, moisture and pH.     DA8K8040.DOC 5/16/90 30-2

Title: Business forms compacting
Inventor: SCHULTZ ELMER G
IPC: B65H45/20
Filed: 1991-07-29
Abstract: Fan folded business forms are compacted so as to provide the maximum run time, and minimum operator effort.  The system includes a folder, transfer table with compacting conveyor, and wheeled cart with a backstop on it.  The backstop is continuously pushed along the cart by the compacting forms until it reaches a position at the end of the cart, at which time a cart full sensor operates an alarm and/or shuts off the folder.  The compacted forms on the cart may be easily moved to any desired location. Forms may be fed either printed side up or printed side down into another piece of equipment.  The main surface of the cart on which the forms travel with their fold lines engaging the main surface, may be manually tilted about a horizontal axis after the cart is full, so that the end of the cart from which forms are to be withdrawn is elevated.  This provides efficient withdrawal of forms while miniminizing curling of the forms.

Abstract: L'invention porte sur des poches auto-gonflantes, utiles comme auxiliaires de sortie dans des distributeurs.  Avec les poches auto-gonflantes existantes, généralement constituées de compartiments voisins renfermant un premier réactif dans une solution aqueuse et un second réactif, soit en solution aqueuse, soit sous forme solide, on s'est heurté à certaines difficultés pour maintenir une production uniforme de gaz dans la poche, ce qui causait un débit irrégulier ou anormal par le distributeur.  L'invention améliore l'uniformité de la production de gaz en fournissant un second réactif à l'état de précipité uniforme dans un milieu de suspension hydrodispersable.  La poche expansible (2) est constituée de plusieurs compartiments renfermant un premier réactif dans une solution aqueuse (30), comme une solution d'acide citrique, et une suspension de gomme hydrodispersable (34) renfermant un second réactif à l'état de précipité, par exemple du bicarbonate de sodium.  Le milieu de suspension hydrodispersable (34) peut aussi renfermer un agent de nucléation et un surfactif.

Patent CA-2058812-A1 (CA)
IPC: E21B43/16
Filed: 1992-01-06
Abstract: A process for improved delivery of mobility control agents.  The drive solvent is designed such that the plugging agent, e.g. surfactant or polymer, is soluble in the drive solvent under the injection conditions of temperature and pressure but is substantially insoluble under the conditions of temperature and pressure in the formation.  Typically, miscible drive solvents have more favorable solvent properties at the low injection temperature than at the higher formation temperature.  Preferably, solute solubility in miscible drive solvents is increased by the use of appropriate cosolvents.  Cosolvent concentration is maintained below the amount needed for solute solubility at reservoir temperatures so that the solute will drop out of solution at some increased temperature depending on the concentration of the cosolvent added to the primary drive solvent.
