Inventor: PELTZ MARSHALL
IPC: H04M3/51
Filed: 2000-04-10
Abstract: An automatic call distribution system and method for using same including an automatic call distributor, an answer detector and an introductory signal generator which generates introductory signals to be sent towards a called party while the answer detector employed by the automatic call distribution center is monitoring for the presence of the called party. When a call that is dialed to the called party by the automatic call distribution system is answered by an external telephonic unit of the called party, the automatic call distribution system couples an answer detector to the call. The answer detector of the automatic call distribution system monitors the call for the presence of the called party while concomitantly sending a generated and coupled introductory signal towards the called party to be heard by the called party.      Preferably, the generated introductory signal simulates background noise. When the called party makes a response, the answer detector then detects the presence of the called party for the purpose of routing the call.

Title: Method and apparatus for using free radicals to reduce pollutants in the exhaust gases from the combustion of a fuel
Inventor: CAREN ROBERT P
IPC: B01D53/00
Filed: 1998-10-06
Abstract: The present invention is an apparatus, and a method for the reduction of pollutants in the exhaust stream of a combustion engine (11). Radicals are produced using a corona discharge device (30, 40, 50, 60, 80, 110) to produce a corona discharge in at least a portion of the combustion gas stream of the engine (11), either from gaseous species in the pre-combustion gas stream or from gaseous species in the exhaust gas stream (18). When the radicals are produced from the exhaust gas stream (18), the radicals may be produced using a corona discharge (30, 40, 50, 60, 80, 110) placed directly in the exhaust stream upstream of or at the catalytic converter (13), or a portion of the exhaust stream (21) may be diverted to a remote corona discharge radical generator (23). The corona discharge (23) in the generator produces radicals in the diverted exhaust gas (21), and the exhaust gas containing radicals (24) is then conveyed to the exhaust gas stream (18) at a point upstream of the catalytic converter (13).

Filed: 1998-10-05
Abstract: A top surface of a protective cover of an IC component package is provided with a centered-protrusion, e.g., such as a cylindrical peg, that extends above the cover. A retaining-spring is formed by twisting a resilient (e.g., metal) metal strip into a ribbon-like shape having opposing ends that extend from a curvilinear bottom surface. The bottom surface of the retaining-spring is provided with an opening configured to mate with the centered protrusion on the package cover, such that the opposing ends of the retaining-spring extend away from the package cover at substantially the same, albeit reverse angles. In order to mount the IC package to a heat sink, the bottom surface of the retaining-spring may be compressively mated onto the package cover at the same time the package is inserted between two substantially parallel walls protruding from the heat sink surface, wherein the walls are distanced from each other just so as to cause moderate compression of the opposing ends of the spring toward each other as the package is inserted against the heat sink surface. The opposing surfaces of the two walls are provided with a plurality of notches formed substantially parallel to the heat sink surface in a "ratchet-type" relief pattern, such that the opposing ends of the retainingspring are held into place by respective notches, once the IC package is secured against the heat sink.
