Abstract: A cardholder system for holding electronic cards used for transactions includes a cardholder having a fraud protection mechanism. The system allows access to a card or to information stored on the card only upon entry of data uniquely identifying the owner of the system and the card or cards contained cardholder. Upon receipt of this identifying data, a card may be removed from the cardholder. The cardholder may also be used for contactless payment transactions without removing the card from cardholder. Accordingly, the cardholder includes an RFID tag or transponder for communication to a BLINK terminal, and the data required for the contactless transaction are transferred from a card in the cardholder to the RFID tag or transponder upon acceptance of the identifying data.

Abstract: The invention relates to a method for connecting reaction sintered silicon carbide parts to iron and other metal parts of importance is that the connection involves the use of a binder comprising a mixture of silicon and a metal and preferrably it is a eutectic mixture.

Abstract: The invention relates to an atomizer burner assembly for oil burners. The assembly has electric heating apparatus for maintaining a relatively constant temperature for the oil supply over a range of throughputs which may vary for different atomizer nozzles, for example, from 0.5 to 2.5 l/h. The heating apparatus includes a PTC resistor mounted in the supply pipe in series with a near zero temperature coefficient heating element which surrounds the supply pipe at a longitudinal position between the PTC resistor and the atomizer nozzle. The PTC resistor controls the heat generated by the heating element in accordance with the temperature of the throughput oil to maintain a constant temperature for the throughput oil.
