Title: Antimicrobial device and method.
Inventor: BAYSTON ROGER
IPC: A61L27/54
Filed: 1988-11-23
Abstract: A medical device made from a material capable of being implanted in living tissue or transcutaneously inserted therein or of long term in-dwelling therein, which exhibits persistent antimicrobial activity in use, and containing a body of a synthetic or naturally occurring material having side surfaces and being capable of being swelled by penetration of a swelling agent and which has been subjected to such a swelling agent which contains completely dissolved therein at least one antimicrobial agent as a solute, the surfaces being contacted by such swelling agent for a sufficient period of time to promote swelling of the matrix of a body of material and thereby permit diffusion and migration of the solution containing the selected antimicrobial agent solute into the interstitial spaces of the body of material at the molecular level by the action of the swelling agent within the body of material, and the solvent being capable of being removed from the solute in the body of material by evaporation and after removal of the solvent the body of material being capable of returning substantially to its original size and shape with the antimicrobial agent substantially uniformly deposited therein for subsequent continuous migration to and diffusion through the surfaces.

Abstract: In particular in the case of bag-in-box packaging receptacles for foodstuffs and for medicaments and other such products, it is a matter of an aseptically and bacteriologically flawless sealing of the filling and removal neck before, during and after completion of the filling process on automatic filling machines. To this end, a sealing foil (5) is arranged on an annular internal adapter (10) with the internal dimensions of the filling and removal neck (3) on a flexible bag (2). The internal adapter (10) can be inserted into the filling and removal neck (3) in such a manner that the sealing foil (5) is first, before the filling process, situated in the outer sealing position (10a) on the filling and removal neck (3) and, during or after completion of the filling process, can be pushed deeper into the neck (3) in such a manner that an external adapter or the like having a sealing cap can be inserted perfectly sealingly into the neck (3). For the complete emptying of such bag packagings, the internal adapter (10) can moreover be provided with a drainage device. <IMAGE>

Abstract: A foveal vision evaluation instrument enables to document the presence and state of foveal degeneration manifested by foveal segmentation and incremental changes and abnormalities in foveal vision, such as are caused by age related macular degeneration (AMD). 
     Beam source optics (10), beam polarization optics (20) and an image selection system (30) provide a polarized projection beam (PPB) that transmits an image array obtained by directing one component of polarized projection beam (PPB) through an image transparency (IT). Image element blanking optics (40) enable the individual elements of the image array to be selectively blanked using a multi-cell electro-optic shutter (45). Zoom projection optics (50) project the image array onto a screen (60) within the foveal field of vision, and allows the size of the projected image elements (65) to be incrementally changed through selective control of zoom magnification with compensating brightness (contrast) adjustment through automatic control of iris setting.

Abstract: On produit un agent pour décolorer par oxydation des cheveux d'êtres humains ou de poils d'animaux en mélangeant immédiatement avant son utilisation un colorant de base pulvérulent, gélatineux ou crémeux contenant un colorant par oxydation, et un agent oxydant, puis en régulant son pH dans une plage comprise entre 8,0 et 10,5. Cet agent contient, lorsqu'il vient d'être préparé, une quantité telle d'un composé acide micro-encapsulé que le pH du colorant est déplacé dans les domaines faiblement alcalin (pH < 8), neutre ou acide. Le matériau d'enrobage du composé acide est soluble dans le colorant alcalin ou au moins modifiable dans le sens de l'affaiblissement de sa solidité. La résistance des parois des micro-capsules est régulée de façon à leur permettre d'être tellement dissoutes ou affaiblies après une durée comprise entre 10 et 60 minutes que le composé acide se déverse tout seul dans le colorant ou à l'aide d'une sollicitation mécanique supplémentaire. L'invention concerne également l'utilisation de l'agent colorant pour renouveler la teinture de cheveux teints.
