Abstract: L'invention concerne un procédé et un appareil de transfert d'informations de données dans un sélecteur numérique. On connait l'utilisation de dispositifs de mémoires dans des sélecteurs numériques pour le transfert d'informations de données. Lorsque l'on utilise des dispositifs de mémoires de sélecteurs selon les techniques actuelles, par exemple dans des sélecteurs du type T-S (Temps-Espace), un grand nombre de dispositifs de mémoires de sélecteurs est nécessaire, ce qui entraîne des problèmes d'espace et d'effet. Le problème est résolu à l'aide du procédé et de l'agencement de l'invention selon lesquels un seul dispositif à mémoire de sélecteur remplace plusieurs dispositifs à mémoire de sélecteur du genre connu. Selon le procédé de l'invention, des informations de données entrent dans un dispositif à mémoire de sélecteur distribué dans les tranches de temps. Les informations de données sont écrites dans le dispositif à mémoire de sélecteur pendant une phase d'écriture pour chaque tranche de temps. Les informations de données écrites dans le dispositif à mémoire de sélecteur sont lues pendantles phases de lecture appartenant aux tranches de temps, et à des fins d'extraction de la mémoire, deux ou plusieurs phases de lecture sont agencées pour chaque phase d'écriture. L'extraction de la mémoire est commandée pour chaque phase de lecture par un dispositif à mémoire de commande séparée.

Title: High efficiency low frequency speaker system
Inventor: KLAYMAN ARNOLD I
IPC: H04R1/02
Filed: 1992-04-15
Abstract: HIGH EFFICIENCY LOW FREQUENCY SPEAKER SYSTEM                     ABSTRACT OF THE DISCLOSURE    A loudspeaker (34,134) excites a quarter wave resonant air column that is folded forward on itself.  The column is closed at one end and has an output port located at the other.   The output port  (20,120)  is in line with the speaker so that the one speaker can excite air both at the output port and at the closed end of the resonant column. At resonance, the column loads the speaker, and the speaker regeneratively  drives  the  column  output.    At  other frequencies  output  from  the  port  is  partially  from vibration of the air column and partially from the speaker. At  resonance  the  direct  speaker  output  regeneratively reinforces and combines with the output of the resonant column, which has a length of one-quarter of the wavelength of sound propagated in air at the resonant frequency.

Abstract: 2067364 9105536 PCTABS00005 Methods and apparatuses are disclosed for preparing novel oxidized lipoprotein compositions. Peroxides are capable of generating free-radicals which, in turn, can oxidize lipoproteins in vitro) or in vivo. It has been discovered that hydrogen peroxide itself or in conjunction with certain enzymes such as peroxidase or lipoxidase can oxidize lipoproteins. Peroxidized low density lipoproteins are the most preferred composition. Oxidized lipoproteins exhibit a cytotoxic effect to which diseased cells which are more susceptible than healthy cells. Thus, oxidized lipoproteins may be useful in treating many disease states. The extent of lipoprotein peroxidation is measured by obtaining a C-13 NMR spectrum of the oxidized lipoprotein solution.
