Abstract: An apparatus and method for inverting a plurality of contact lenses between separate processing steps which treat the opposite concave and convex surfaces of the lenses. The lenses are initially placed convex side-up on a perforated lens support surface and are subjected to the first processing step which treats this surface of the lens. The support surface is then passed over an elongated air stream which traverses and is directed to impinge upon the bottom surface of the support whereby the air stream passes through the perforations in the support and inverts the lenses from the convex side-up position to a concave side-up position whereupon this surface of the lenses may be treated in a subsequent processing step.

Title: Method and system providing unified dpsk-psk signalling for cdma-based satellite communications
Inventor: HO JIN-MENG
IPC: H04J13/00
Filed: 1997-08-21
Granted: 2001-08-07
Abstract: A method and a system for multi-user communications in a CDMA-based satellite network. An uplink RF signal containing a coded user message that has been differentially phase encoded and spread using a Walsh function and a pseudo-random number (PN) sequence for the uplink, is received by a satellite receiver. The received uplink RF signal is non-coherently quadrature demodulated and then despread using the uplink PN sequence and Walsh function. The differential phase signal carrying the coded user message is regenerated onboard the satellite by phase comparison and switched to a selected downlink transmitter. The quadrature components of the differential phase signal are then respread using a Walsh function and a PN sequence for the downlink, followed by quadrature modulation for transmission to a terrestrial receiver. The received downlink RF signal is coherently quadrature demodulated and despread using the PN sequence and Walsh function for the downlink. The downlink carrier phase originated from the uplinkdifferential phase is regenerated from the despread quadrature baseband components and, hence, the coded user message is detected and decoded.

Granted: 2001-05-29
Abstract: Système de suppression de fréquences améliorant la réception d'un signal transmis à une fréquence donnée en présence d'un signal brouilleur se produisant à la même fréquence de transmission. Le système de suppression de fréquences génère un signal de référence à la fréquence de transmission et règle le signal de référence de manière à ce qu'il soit en phase opposée et d'amplitude égale par rapport au signal brouilleur. Le signal de référence et le signal de communication sont ensuite combinés pour supprimer le signal brouilleur. Dans une application préférée, le signal de référence est généré par la même source que celle d'où provient le signal brouilleur. De préférence, le signal brouilleur est reçu pendant un intervalle durant lequel le signal de transmission n'est pas transmis, et le signal de référence est réglé de manière à être en phase opposée et d'amplitude égale par rapport au signal brouilleur pendant cet intervalle.

Title: Process for preparing a chlorine-dioxide-containing disinfectant solution for water treatment
Inventor: KUKE FRITZ
IPC: C02F1/72
Filed: 1996-04-24
Granted: 2005-03-08
Abstract: The present process proceeds from an aqueous reaction solution containing a chlorite and a halogen-free oxidizing agent which is present in an excess of up to double the required stoechiometric amount. The pH of the reaction solution is set at between 5.5 and 9.5, preferably between 6 and 9, and the reaction solution is reacted at ambient temperature until almost all the chlorite has been converted into chlorine dioxide. In this way a chlorine dioxide-containing solution is obtained which is free not only from residual chlorite but also from chlorate and other undesirable by-products and can be used directly as such in water treatment. Preferably an aqueous chlorite solution with a pH of more than 9.5 and an aqueous solution of the oxidizing agent are mixed with one another in order to produce the reaction solution, the pH of the aqueous reaction mixture being adjusted by means of a proton donor present in the oxidizing agent solution. In this way a two-component reaction product is advantageously obtained which need only be mixed in a predetermined ratio in order to produce a fresh chlorate-free chlorine dioxide solution. It is further advantageous to add to the aqueous chlorite solution or aqueous oxidizing agent solution a buffer substance which forms a buffer system which is active between pH 5.5 and pH 9.5 in the reaction mixture, thus further stabilizing the pH set. The preferred presence of at least catalytic amounts of silver ions or ions of other transition metals in the reaction solution has a positive effect on the conversion of chlorite ions into chlorine dioxide.
