Title: Paging receiver having data speed detector for continuing address receiving mode
Inventor: KURAMATSU HIROYASU
IPC: H04W88/02
Filed: 1993-04-19
Granted: 1999-04-13
Abstract: In an address receiving mode of a paging receiver, an address codeword contained in each successive batch of a paging signal is compared with the address of the receiver to detect a match. The speed of data pulses generated by the receiving section are checked to see if it is in a prescribed speed range. If the receiver fails to detect an address match in one of the batches due to fading, it continuously receives the address codewords in successive batches, rather than returning to standby mode, if the data pulse speed is determined to be in the prescribed range.

Title: Apparatus for opening and closing a taphole of a metallurgical furnace
Inventor: WINCH REGINALD W
IPC: C21C5/46
Filed: 1993-05-07
Granted: 1996-04-23
Abstract: An improved apparatus for opening and closing a taphole of a metallurgical  furnace  includes  stationary  pedestal  sections carrying an upper boom and a lower boom which booms can be slewed by driving means independently from each other with one of their ends around the pedestal.  To one of the booms a drilling machine is connected and to the other a taphole-plugging machine.   The swing paths of the booms are inclined relative to each other, such that the two machines can be swung into parked positions, at heights suitable for operations and maintenance, and each into its servicing position in front of the taphole.   Preferably, the drilling machine is connected to the upper boom.  Also preferably, the connection between each boom and the pedestal is accomplished by two vertically separated large diameter slewing bearings, and by driving  means  consisting  of  two  hydraulic  cylinders.    The inclination of the axis of rotation of the two booms,  in the vertical  plane  of  the taphole,  will  be determined  for  each installation,  from the relevant heights of the operating and parking required locations of the drilling and plugging machines. The inclination of the axis of rotation normal to the above plane for each boom will also be determined for each installation by the clearance necessary as the upper boom assembly passes over the lower  boom.    The  preferred  angles  of  inclination to  give satisfactory elevations and clearances are for the upper boom between 0 and 2 degrees towards the taphole plane and between 8 and 10 degrees towards the furnace in the plane normal to the above. For the lower boom, the angles are between 4 and 6 degrees away from the plane of the taphole and between 2 and 4 degrees towards the furnace.

Abstract: The radio frequency transceiver (300) was developed for use in a time division duplex (TDD) radiotelephone communication system. The transceiver includes a local oscillator (303) which generates at least two local oscillator signals (113) at different times. Each local oscillator signal (113) has a unique frequency. During a first time period, the radio frequency transceiver (300) receives a radio frequency signal (107). The first radio frequency signal (107) is combined with one of the local oscillator signals (113), forming an intermediate frequency signal (311). During a second time period, the transceiver (300) generates a frequency offset signal (312). The frequency offset signal is combined with the second local oscillator signal, (113) forming a second radio frequency signal (107). The intermediate frequency signal (311) and the offset frequency signal (313) are designed to have different frequencies to avoid the self-quieting problem inherent in a TDD communication system.

Title: Apparatus and method employing polarization modulation to reduce effects of polarization hole burning and/or polarization dependent loss
Inventor: HEISMANN FRED LUDWIG
IPC: H04B10/135
Filed: 1994-06-29
Granted: 1998-06-16
Abstract: The effects of polarization dependent hole burning and/or polarization dependent loss are reduced by modulating the state of polarization (SOP) of an arbitrarily polarized optical signal being launched into the transmission path periodically through a predetermined sequence of polarization states. The sequence of polarization states is selected such that on average the launched modulated signal excites substantially all possible polarization states with substantially equal probability, independent of the input SOP to the polarization modulator. In one exemplary embodiment, the SOP is modulated by a combination cascade of a rotating half-wave plate followed by a quarter-wave plate, which rotates at a different angular speed. In another exemplary embodiment, the SOP is modulated by a combination cascade of two variable phase retarders oriented at fixed angles of 0° and 45°, where the modulation frequencies of the two retarders are substantially different from each other.
