Title: Alkaline leaching of galvanized steel scrap
Inventor: LEEKER JERALD W
IPC: C22B19/20
Filed: 1991-10-07
Abstract: Caustic dezincing galvanized steel scrap. A dezincing plant includes a plurality of tanks (14, 16, 18) interconnected in series with steel scrap sequentially being moved through each of the tanks. The tanks (14, 16, 18) contain a caustic leaching solution including an oxidant with the leaching solution being circulated through each of the tanks (14, 16, 18) in a direction opposite to the movement of the scrap. Fresh scrap initially is exposed to a partially depleted leaching solution with the oxidant concentration of the leaching solution increasing as the scrap moves through the series of tanks (14, 16, 18). Leaching solution depleted of its oxidant is transferred to an electrolytic cell (22) where zinc is removed and plated as metallic zinc powder onto a cathode. The leaching solution is recycled by removing zinc. The chemistry of the leaching solution is controlled so that sufficient free caustic is present to prevent passivating zinc coating on the scrap. Oxidant is added to the recycled solution and the caustic concentration is adjusted, if necessary, to have a total caustic concentration of at least 5 M and the recycled solution is returned to the last tank (18). Compressed scrap bales are dezinced and ready for use as a melting furnace charge material. <IMAGE>

Title: Determining the position of a mobile station in a CDMA cellular telephone system
Inventor: GILHOUSEN KLEIN S
IPC: H04W64/00
Filed: 1997-06-06
Granted: 2001-08-15
Abstract: In a cellular communications system, a mobile is in communication with a first base station via a radio channel. The mobile may be located by measuring signal propagation delays between itself and the first base station, and between itself and a second and third surrounding base station. If, whilst the first base station is transmitting, the mobile is unable to perform the necessary measurements with the second and third base stations, the first base station will temporarily cease transmitting on the radio channel to enable the mobile to measure the propagation time of a signals between itself and the second and third base stations. Particularly suited to CDMA communications systems in which transmission powers are normally kept to a minimum.

Title: Apparatus and method for controlling transmission parameters of home network stations
Inventor: JUNG KYONGSOO MICHAEL
IPC: H04L12/56
Filed: 1999-05-14
Granted: 2003-07-23
Abstract: A physical layer transceiver of a home network station connected to a telephone medium has an architecture enabling adaptation of detection circuitry based on received network signals to enable reliable recovery of data signals. The physical layer transceiver includes an input amplifier that amplifies network signals according to one of 128 gain settings set by a receiver gain control signal. A signal conditioning circuit includes an envelope detector configured for outputting an envelope of the amplified received signal, and an energy detector configured for outputting an energy signal of the amplified received signals. The envelope signal and the energy signal are supplied to slicer threshold circuits, configured for outputting noise, peak, data event and energy event signals based on noise threshold, peak threshold, data transition threshold, and energy threshold signals, respectively. A digital controller controls the input amplifier gain and the threshold values, and adjusts the gain and threshold values based on the noise event signal and the peak event signal within an access ID (AID) interval. A link controller monitors the number of errors in received data packets, and causes the media access controller and physical layer transceiver to output AID command packets that signal a transmitting station to reduce transmit data rate or increase transmit power to improve reception reliability on the telephone line medium.

Title: Pipe coupling
Inventor: HEHL KARL
IPC: F16L19/03
Filed: 1985-05-29
Granted: 1988-07-27
Abstract: A pipe coupling having an annular gasket deformed and compressed within a closed gasket chamber to form a seal for a pressurized hydraulic line, for example, one wall of the gasket chamber being formed by the outer surface of a pipe end portion which is to be connected either to a second pipe end portion or to a wall port. The axial width of the gasket chamber is determined by an abutment of the end face of the pipe end portion which transmits the abutment force to a threaded clamping sleeve or, as the case may be, to a coupling nut with the aid of a snap ring which engages a peripheral groove of the pipe end portion and a thrust shoulder of the threaded clamping sleeve. The pipe-to-pipe version of the coupling has two annular gaskets inside identical gasket chambers on opposite axial sides of a centering sleeve which surrounds both pipe end portions.

Title: A method for reducing equalizer usage in mobile radio communication systems
Inventor: UDDENFELDT JAN ERIK
IPC: H04B7/26
Filed: 1991-09-05
Granted: 1995-02-01
Abstract: A method in a mobile radio station to select one of a number of dedicated control channels (DCCH1-21) which are transmitted from a number of base stations (B1-B21) in a mobile radio system. In the mobile station there is an equalizer to compensate for the multipath propagation characteristics of the radio medium between the mobile station and a certain base station. This equalizer is power consuming and should not be used if not necessary. According to the method an investigation is carried out in the mobile station whether or not the equalizer can be disconnected during the initialization of a call from the mobile to a base station. The signal quality of the dedicated channel (DCCH1) which has the greatest signal strength is measured without the equalizer. If the signal quality is not acceptable, a new detection is made with the use of the equalizer. If the signal quality then is acceptable another detection is made without equalizer on the dedicated control channel (DCCH2) which has the next strongest signal and if this detection revealed an acceptable signal quality the base station (B2) transmitting this control channel is selected by the mobile station for the further call progress.

Access control apparatus 16100-1, 16120-1 etc of the ICS 16000-1, convert between ICS user frames external to the ICS and ICS network frames within the ICS. Data to be provided by the DPC is sent from the DPC to the STC. A link is established through the ICS between the DPC and the users, by means of TCP protocol operating between IP terminals 16210-1, 16310-1, 16501-1 etc. The link is used to initiate download of the data from the STC over the satellite channel, 16600-1, 16400-1 16610-1 etc. It is stated that this provides full duplex communication. Instead of TCP protocol, the system may use UDP protocol consisting of TCP without the connection establishment or connection ending phases. Download can be initiated by an inquiry from a user, or by a notification from the DPC. In an alternative arrangement, the satellite forms part of the ICS network.
