Filed: 1995-12-11
Abstract: Disclosed is a connector, which is provided in a IC card body, wherein a socket or a jack is inserted in a direction that is parallel to the face of an IC card. According to the present invention, provided on an IC card body 302 is a flat plate member 305 incorporating a rotatable housing 306, which has an opening 312 by which a socket or a jack can be fitted, that is attached to the flat plate member 305. With this structure, when a socket or a jack is not connected to the IC card, the flat plate member 305 lies level along the face of the IC card; but when a socket is to be connected, the housing 306 of the flat plate member is raised so as to be substantially perpendicular to the face of the IC card. The socket or the jack can therefore be inserted parallel to the face of the IC card, and even when an adjacent IC card is loaded, interference with that IC card is minimal.

Patent CA-2173355-A1 (CA)
Title: Method and apparatus for multiple media digital communication system
Inventor: RICHTER ANDREAS
IPC: H04L12/56
Filed: 1994-06-08
Abstract: The present invention is embodied in a digital communication system where multiple media data sources are time multiplexed into a packetized data stream, each packet having an assigned priority and the packetized data stream transmitted in substantially the order of assigned priority. At both the transmit side, and the receive side, audio packets are given priority processing over video packets, which in turn have priority over text/graphics data packets. Continuous real time audio playback is maintained at the receiver by delaying the playback of received audio in a first in/first out (FIFO) buffer (734, 742) providing a delay at least equal to the predicted average packet delay for the communication system. Optionally, the average system delay is continuously monitored, and the audio playback delay time is adjusted accordingly. Audio playback is slowed or accelerated in order to shrink or grow the difference in time between the sender and receiver. In another aspect of the invention, a  conference of three or more callers is created by broadcasting a common packetized data stream to all conference callers.

Title: Time stamp correction in atm network
Inventor: LOGSTON GARY L
IPC: H04L12/56
Filed: 1995-01-09
Abstract: A packet of data, which contains a timestamp value and which is to be transmitted through an ATM network, is encapsulated in a convergence sublayer protocol data unit (92) having a header (96) and a payload (94). The CS-PDU is then segmented into successive segments (106, 108, 110 and 112) with one segment (106) containing the CS-PDU header (96). The segments (106, 108, 110 and 112) are inserted in respective ATM cells (114, 116, 118 and 120) and transmitted through the ATM network. At each node in the ATM network, any variable delays imposed on the cell (114) that contains CS-PDU header (96) are added to a time reference correction field (100) in the CS-PDU header (96). At a destination node, the accumulated delay value in the TRC field (100) of the CS-PDU header (96) can be added to the timestamp value of the packet to compensate for the variable delays imposed by the ATM network.

Title: Removal of hydrogen sulfide from anaerobic digester gas
Inventor: SPIEGEL RONALD J
IPC: B01D53/52
Filed: 1995-06-23
Abstract: The effluent gas stream from anaerobic waste water treatment digesters is treated to remove trace amounts of hydrogen sulfide and other contaminants. The chemical equation involved relies on the reaction of hydrogen sulfide with oxygen to form water plus elemental sulfur. The removal system includes a variable control line for adding air to the effluent gas stream; a filter for removing solids, entrained liquids and bacteria from the oxygen-enriched gas stream; a blower for directing the filtered gas stream into a potassium promoted activated carbon bed wherein the above chemical reaction takes place; and sensors for measuring the content of oxygen and hydrogen sulfide at the entrance and exit of the activated carbon bed. When the hydrogen sulfide content of the exiting gas stream exceeds a predetermined level, the amount of air added to the gas stream is increased until the predetermined level of hydrogen sulfide is achieved in the exiting gas stream.

Title: Fluid catalytic cracking process
Inventor: TERRY PATRICK HENRY
IPC: B01J8/08
Filed: 1996-09-20
Abstract: Disclosed is a fluid catalytic cracking process in which the catalytic cracking reaction takes place in a dilute phase, and the reaction product contains a reduced volume of off gas having a low concentration of SOx and NOx. The use of off gas, which is produced during a regeneration step, to strip entrained vapor from spent catalytic cracking catalyst acts to reduce SOx and NOx byproducts, and eliminates the need to separately recover and treat the off gas stream from the regenerator portion of the system. The entire process, including the reaction step, the stripping step and the regeneration step, can be performed in a single vessel, and the stripping and reaction steps take place entirely in the dilute phase.
