Abstract: A wearable hands-free apparatus for providing phototherapy treatment to a number of hair, scalp and skin related conditions includes a head unit (e.g., a headset, headphones, headband, or helmet unit) with earphones to allow the user to listen to an audio program during a treatment. The head unit supports a light emitting canopy band that is fitted with an array of light generating sources, such as light emitting diodes (LEDs), laser diodes, or infrared lights, that emit light within a particular wavelength range correlating with the treatment of one or more specific hair, scalp and/or skin-related conditions. The light emitting canopy band is specifically designed to conform to the shape of the human scalp for providing complete, uniform and consistent light coverage to the areas of the scalp that are most commonly affected by hair loss in men and women. A handheld control device allows the user to select the desired treatment program and is adapted for connection to a digital audio player device, such as an MP3 player, for delivering audio signals to the earphones.

Title: Method of acidizing a subterranean formation with diverting foam or fluid
Inventor: CAWIEZEL KAY C
IPC: C09K8/70
Filed: 2004-07-16
Granted: 2014-09-16
Abstract: A method of acidizing a subterranean formation with a diverting agent composed of a gelled or thickened viscoelastic foam or fluid generated from (i.) an amidoamine oxide gelling agent and (ii.) an acid or foam, water and/or brine. The gelled or thickened foam or fluid may be generated in-situ or introduced directly into the formation by mixing of the amidoamine oxide gelling agent and acid or foam, water and/or brine. As the acid spends, the acidizing fluid thickens. When the acid is further spent, the fluid viscosity declines eventually returning to a low viscosity state, allowing for easy cleanup. The process allows for selective acidizing of less permeable zones of the formation and more uniform stimulation of the hydrocarbon bearing formation.

Abstract: L'invention porte sur une tige composite devant être utilisée dans diverses applications, telles que des câbles électriques (par exemple des câbles de transmission haute tension), des câbles ombilicaux d'énergie, des attaches, des cordes et une grande diversité d'autres éléments structuraux. La tige comprend une partie centrale qui est formée d'une pluralité de mèches de fibre alignées de manière unidirectionnelle et incorporées à l'intérieur d'une matrice polymère thermoplastique. Selon la présente invention, le degré selon lequel les mèches sont imprégnées de la matrice polymère thermoplastique peut être amélioré de manière significative par la commande sélective sur le procédé d'imprégnation et par la commande sur le degré de compression communiqué aux mèches pendant la formation et la mise en forme de la tige, ainsi que sur la calibration de la géométrie de tige finale. Une telle tige bien imprégnée présente une fraction de vide très faible, ce qui mène à d'excellentes propriétés de résistance. Notamment, les propriétés de résistance souhaitées peuvent être obtenues sans avoir à utiliser différents types de fibres dans la tige.
