  • Patent number: 9361547
    Abstract: An electronic device includes a housing for safely breaking electronic communication with a smart card on removal from the electronic device. A safeguard structure rotates with respect to the housing to cover the smart card when inserted, and a switch breaks communication between the smart card and the electronic device when the safeguard structure is rotated away from the housing to enable removal of the smart card. The breaking of communication safely prevents damage to, or corruption of, data in the smart card upon removal from the electronic device.

  • Patent number: 7282606
    Abstract: The present invention discloses a new process for the synthesis of tamsulosin and its aralkylamine derivatives, especially (R)-(?)-5-{2-[2-(2-alkoxyphenoxy) ethylamino]propyl}-2-alkoxybenzenesulfonamides having the following formula 1 (where R1 and R2 represent C1-C4 alkyl groups) and their hydrochloride thereof, and other various pharmaceutical used salts. Tamsulosin hydrochloride (R1=Et, R2=Me, in its hydrochloride salt form) is an antagonist of ?-A adrenoceptors in the prostate. Tamsulosin•HCl occurs as white crystals, which melt with decomposition at approximately 230° C. It is sparingly soluble in water and in methanol, slightly soluble in glacial acetic acid and in ethanol, and practically insoluble in ether.

  • Patent number: 5386872
    Abstract: A refinery petroleum gas recovery apparatus driven by normally wasted heat, comprising primarily the cooling system, the heat exchanging petroleum gas recovery system, and the appropriate peripheral equipment, wherein the wasted heat from the refining process is used as a power source for creating a vacuum cooling function to cool the water being heat exchanged with the petroleum gas down to the temperature of 12.degree.-13.degree. C. The heat in the gas is removed and the gas is condensed into liquid for reuse. The petroleum gases ethane, propane etc. which are ordinarily burned in the torch tower can now be recovered for reuse. The air pollution created from the burning of the gases in the torch tower is eliminated. Thus the apparatus has a high industrial value.
