Title: Method for regenerating platinum group metal suspension catalysts
Inventor: HERZOG HANS
IPC: B01J23/44
Filed: 2000-07-05
Granted: 2009-09-15
Abstract: The regeneration of platinum group metal suspension catalysts involves a dissolution step using HC1 and an oxidant, such as Cl2 or H2O2, and a precipitating step carried out in the presence of a reducing agent, especially an aldehyde, an HCOOH or a formiate. According to the invention, the content of non-platinum metals which are dragged into the catalyst as a result of the method can be reduced by carrying out the precipitation in the presence of a chelate complexing agent for one or more metals selected from the series of metals of groups 2a, 3a, 4a of the periodic table and of the transition elements without elements of the platinum group.

Abstract: Techniques for an electronic shelf label (ESL) system which uses a digital modulation technique for a modulated backscatter uplink from an ESL to a communication base station (CBS) which utilizes pseudo-random sequences instead of a single continuous wave frequency. The CBS transmits a message to an ESL using a Manchester coded amplitude modulated carrier. After receiving the message, the ESL responds by reflectively modulating a continuous wave (CW) signal with a pseudo-random code sequence. Multiple pseudo-random code sequences may be chosen, with each code sequence corresponding to a particular response. The code sequence is modulated onto a kHz carrier which is used to reflectively modulate the CW signal received from the CBS. The CBS then receives the reflectively modulated signal and correlates the received signal to determine message transmitted.
