Patent CA-2416371-A1 (CA)
Inventor: TUTT HARVEY DONALD
IPC: A63B47/02
Filed: 2003-01-22
Abstract: The invention, named Slimpickens, is a golf ball retrieving and dispensing device designed to provide the golfer with the opportunity to pick up and disperse golf balls without bending down. It is constructed of durable, light weight plastic tubing with no moving parts. The resilience of the tube allows the golf balls to pass by inner lugs when downward pressure is applied. The inner lugs hold the golf ball within the tube. The tube will hold 23 golf balls. On the entry end the lugs are slightly larger than the lugs on the dispensing end. To disperse golf balls the unit must be inverted. A shaking motion will allow the balls to come out of the tube one at a time. A cap is provided for the dispensing end to prevent the balls from coming out of the tube when the unit is used for storing balls.      Apparatuses of the type disclosed have not been found.

Abstract: L'invention concerne un circuit onduleur de ballast auto-oscillant conçu pour alimenter une lampe à décharge gazeuse. Ce circuit est utilisé dans un onduleur de ballast pour corriger le glissement de fréquence de résonance positif de la charge de l'onduleur pendant le démarrage de la lampe. Le circuit est fabriqué à partir de composants faible puissance et il fait partie intégrante d'un onduleur donnant un angle d'avance transitoire destinés aux transistors de commutation de l'onduleur (M1, M2). Cette avance angulaire est augmentée proportionnellement à la tension de sortie incrémentale de l'onduleur dépassant une tension seuil définie. Cela permet à l'onduleur de travailler au dessus de la fréquence de résonance pendant le démarrage de la lampe, évitant ainsi des conductions croisées transitoires entre les transistors du circuit. Le circuit de rétroaction permet de limiter les contraintes de tension et de courant pouvant endommager, à terme, certains composants du ballast. Le circuit génère également un signal destiné à un circuit de protection qui est activé en cas de défaut de démarrage de la lampe. Après démarrage de la lampe, le circuit de rétroaction revient à sa plage linéaire.

Title: Process for making platelets
Inventor: JOSEPHY KARL
IPC: C09D7/61
Filed: 2002-05-06
Abstract: A process for making functional or decorative flakes or platelets comprises applying a multi-layer sandwich of vapor deposited metal (46, 48, 50) and release coats (44) in alternating layers to a rotating chilled drum (36) or suitable carrier medium contained in a vapor deposition chamber (30). The alternating metallized layers are applied by vapor deposition and the intervening release layers are preferably solvent soluble thermoplastic polymeric materials applied by vapor deposition sources contained in the vapor deposition chamber. The multi-layer sandwich built up in the vacuum chamber is removed from the drum or carrier and treated with a suitable organic solvent to dissolve the release coating from the metal in a stripping process that leaves the metal flakes essentially release coat free. The solvent and dissolved release material are the removed by centrifuging to produce a cake of concentrated flakes which can be air milled and let down in a preferred vehicle and further sized and homogenized for final use in inks, paints or coatings.
