Abstract: A self-propelled core-cutting apparatus is used to cut circular slots in pavement extending about manhole castings and the like to permit castings and surrounding cores of pavement to be removed quickly and easily for such purposes as elevating the level of manhole castings to align with new pavement.  The appa-ratus has a transport carriage to which are connected 1) a large diameter,  generally  cylindrical  core-cutting  bit,  2)  power-operated support and drive systems mounting the bit for vertical and rotary movement relative to the carriage along and about a vertically extending center axis, and 3)  a power-operated sta-bilization system that makes use of the weight of the apparatus in maintaining desired positioning of the apparatus during cut-ting operations.  Support for the core cutting bit is provided by a telescopically extensible array of cage-like structures that extend substantially concentrically about the center axis, inclu-ding an outer cage that is rigidly connected to the carriage, and an inner cage that is movable vertically relative to both the outer cage and the bit.  Job site positioning of the apparatus is effected by using lever or joystick controls to operate a fluid-motor-driven power-steerable wheel that also serves as one of three vertically movable components of the power-operated stabi-lization system.  Preferred practice of the invention also makes use of other disclosed features.

Abstract: A shaft furnace, e.g. a blast furnace, has a bosh, a shaft and a mantle ring at the transition from the bosh to the shaft.  At both the bosh and the shaft, there is a steel jacket and a refractory lining on the inside of the steel jacket.  Cooling elements extend into the refractory lining from the steel jacket and are arranged for through-flow of cooling liquid.  To provide additional cooling at the critical transition from the bosh to the shaft adjacent the mantle ring, there is at least one transition cooling element located near the mantle ring so as to cool a region of the refractory lining of the bosh adjacent the steel jacket at the transition.  The transition cooling element has, as seen in plan view, a T-shape, with the cross-bar of the T-shape extending in the circumferential direction of the furnace.

Abstract: An optical tape duplicator is disclosed for making multiple copies of recorded optical tape by continuous contact recording. An information-bearing endless master tape is brought into intimate contact with an optical tape and passed through a recording zone exposed to a beam of radiant energy for recording information stored by the master tape into the optical tape. The master tape contains transmissive and non-transmissive portions that represent the information stored by the master tape. The optical tape contains a recording surface that is sensitive to the radiant beam of energy. The beam of radiant energy passes through the transmissive portions of the master tape while making contact with the optical tape in the recording zone, causing information stored by the master tape to be recorded in the recording surface of the optical tape as indicia where the recording surface was exposed to the beam of radiant energy.

Title: Automatic signal analyzing system for identification and analysis of facsimile signals in telephone signal transmissions
Inventor: KUMAKURA HIROSHI
IPC: H04N1/00
Filed: 1995-06-29
Granted: 1999-12-28
Abstract: An automatic signal analyzing system for identification and analysis of facsimile signals in telephone signal transmission includes a switch unit, a service trunk, a signal identification trunk, a facsimile communication determination unit, and a control unit. The signal identification trunk restores a facsimile control signal from a modulated and encoded signal on the set speech path and performs collection of communication state information and detection of a start of facsimile communication on the basis of the restored facsimile control signal. The facsimile communication determination unit permits operation of the signal identification trunk when the classification result from the service trunk represents a type other than the voice signal and analyzes the communication state information from the signal identification trunk. The control unit performs switching/connection control of the switch unit, connects the service trunk and the signal identification trunk, both of which are in an idle state, to the set speech path upon setting of the speech path, disconnects the service trunk from the speech path when the classification result is output, and disconnects the signal identification trunk from the set speech path when the classification result from the service trunk represents the voice signal and when a call corresponding to the set speech path is ended.

Title: Polymers for separation of biomolecules by capillary electrophoresis
Inventor: MADABHUSHI RAMAKRISHNA S
IPC: C08G63/08
Filed: 1994-12-06
Granted: 1999-09-14
Abstract: The invention provides uncharged water-soluble silica-adsorbing polymers for suppressing electroendoosmotic flow and to reduce analyte-wall interactions in capillary electrophoresis. In one aspect of the invention, one or more of such polymers are employed as components of a separation medium for the separation of biomolecules, such as polynucleotides, polysaccharides, proteins, and the like, by capillary electrophoresis. Generally, such polymers are characterized by (i)water solubility over the temperature range between about 20.degree.C to about 50.degree.C, (ii) concentration in a separation medium in the range between about 0.001 % toabout 10 % (weight/volume), (iii) molecular weight in the range of about 5 x 103to about 1 x 106 daltons, and (iv) absence of charged groups in an aqueous medium having pH in the range of about 6 to about 9. In one embodiment, polymers of the invention are selected from the group consisting of polylactams,such as polyvinylpyrrolidone; N_N disubstituted polyacrylamides; and N-substituted polyacrylamides. In accordance with the method of the invention, a sufficient amount of polymer adsorbs to the capillary surface to establish a zone of high viscosity that shields the analyte from the wall and impedes the movement of, anelectrical double layer under an electric field.

Title: Code division multiple access system providing load and interference based demand assignment service to users
Inventor: I CHIH-LIN
IPC: H04J13/00
Filed: 1996-09-04
Granted: 1999-12-14
Abstract: A code division multiple access system provides a way of allocating an increased data rate to a requesting mobile station. A mobile station requesting a data rate in excess of the basic data rate sends received pilot strength data for its base station and base stations in adjacent cells. The received pilot strength data is used to determine an increased data rate to be assigned to the requesting mobile station. One feature assigns an increased datarate when the received pilot strength data has a predetermined relationship to an established threshold. Another feature utilizes a series of threshold levels, each pair of levels associated with a different permitted data rate. Using the received pilot strength data, a data rate is determined which satisfies all adjacent cellinterference concerns. Another feature uses average adjacent cell capacity loadsrather than threshold levels, together with the received pilot strength data, todetermine the appropriate increased data rate to be assigned to a user requesting an increased data rate.
