Granted: 2002-07-23
Abstract: A toothbrush for use by wearers of orthodontic appliances comprises an elongated handle, a neck and a head. The bristles are designed so that the outermost rows are relatively soft and of long length, the bristles in the pattern gradually shortening in length and becoming stiffer, with the shortest and stiffest bristles being positioned along the center rows of the brush's longitudinal centerline axis. Also, the center rows of bristles are formed to be angled at their ends to reduce the pressure required to deflect the bristles beneath brace elements thus reducing undue pressure against the gums. Furthermore, a flexible member compressibly supports the center rows of bristles. The toothbrush also comprises an outer bumper protectively surrounding the toothbrush head. Moreover, a further embodiment of the invention has a lower tuft of bristles projecting from the lower portion of the handle.

Title: Method and plant for dealing with mercury-containing waste
Inventor: LINDGREN PER-OLOV
IPC: H01M10/54
Filed: 1994-10-31
Granted: 1998-09-29
Abstract: A method for dealing with mercury-containing waste including button-type batteries,  wherein the waste is heated in a furnace while being agitated and in the presence of elementary selenium vapour in an amount sufficient to form mercury-selenide from essentially all the mercury contained by the waste. The waste is heated to a temperature at which mercury and selenium will be present in a gaseous state and at which solid mercury-selenide will not form, and a partial pressure of oxygen is maintained at a sufficiently low level to avoid oxidation of the selenium. The thus treated mercury-freed waste is extracted from the resultant process gas and from any other solid material that may be present and is either dumped or  worked-up  metallurgically.  After  the  waste  has  been extracted from the process gas, the process gas is cooled to extract therefrom solid, stable mercury-selenide dust suitable for dumping, whereafter the gas is passed through a filter with the intention of extracting any gaseous mercury that may remain in the gas,  whereafter the thus cleansed gas  is released to atmosphere. The invention also relates to plant for dealing with mercury-containing waste.

Abstract: Le  beta -carotène, le lycopène et la canthaxanthine, comme caroténoïdes représentatifs, et dans une moindre mesure, l'acide rétinoïque, un rétinoïde représentatif, subissent une oxydation intensive pour donner des substances, dans la mesure où le  beta -carotène oxydé est un modèle, qui présentent des propriétés utiles comme agents non toxiques actifs contre la prolifération cellulaire, les tumeurs, et les virus tumorigènes, et utiles commme promoteurs de la différenciation cellulaire. D'après l'analyse chimique du mélange de produits au  beta -carotène fortement oxydé, il est évident qu'aucune des formes variées de la vitamine A n'est présente ou que ces formes ne sont présentes qu'en petites quantités. En outre, les activités biologiques de la canthaxanthine et du lycopène oxydés, lesquels ne peuvent former de vitamine A, révèlent la présence de substances actives différentes de la vitamine A. Bien que les activités cytostatiques et de promotion de la différenciation cellulaire du  beta -carotène oxydé ressemblent à celles de la vitamine A elle-même, les effets sont en général plus puissants pour le  beta -carotène oxydé dans une grande variété de circonstances. A la différence de la vitamine A, le  beta -carotène oxydé décrit n'est pas toxique. Le caroténoïde oxydé est un mélange de composés qui peuvent être divisés en un certain nombre de fractions selon le poids moléculaire et la polarité. Ces fractions présentent une activité anticancéreuse comparable ou supérieure à l'activité du caroténoïde oxydé non fractionné.

Granted: 2002-09-10
Abstract: In a method for measuring a distance between a conducting reaction track and a functional surface moving relative to the reaction track a sensor with two signal transmitters is provided on the functional surface. An alternating field is generated in the sensor. The alternating field changes as a function of the distance between the conducting reaction track and the functional surface.          Each of the two signal transmitters detects the changes of the alternating field as distance information. Each signal transmitter produces decoupled distance information values.    These decoupled distance information values are processed in separate distance measuring channels to provide processed signals. The processed signals are constantly fed to and compared in a comparator.  A distance information signal is emitted only when the processed signals of the separate distance measuring channels are identical within a predetermined tolerance range.
