Granted: 2007-06-12
Abstract: Disclosed is a method for determining whether a first protein is capable of physically interacting with a second protein.  The method involves: (a) providing a host cell which contains (i) a reporter gene operably linked to a protein binding site; (ii) a first fusion gene which expresses a first fusion protein, the first fusion protein including the first protein covalently bonded to a binding moiety which is capable of specifically binding to the protein binding site; and (iii) a second fusion gene which expresses a second fusion protein, the second fusion protein including the second protein covalently bonded to a weak gene activating moiety; and (b) measuring expression of the reporter gene as a measure of an interaction between the first and the second proteins. Such a determination facilitates the isolation of the gene encoding the interacting protein. Also disclosed herein is recombinant Cdi1 polypeptide, nucleic acid encoding the Cdi1 polypeptide, and uses thereof.

Abstract: An improved rotary blowout preventer having a rotary housing rotably mounted within an outer housing and carrying an annular packer assembly hydraulically actuated by fluid circulated through the outer housing by hydraulic pumps.  An annular adapter is detachably and reattachably connected to an upper rim of the rotary housing.  The adapter has a tubular, elastomeric sleeve detachably and reattachably connected thereto that depends within the rotary housing adjacent the packer assembly.  A drill pipe is received within the sleeve and is sealably engaged thereby when the packer assembly is urged inwardly by the circulated hydraulic fluid.  The sleeve protects the packer assembly from wear and is easily replaced with other sleeves of like configuration.  The sleeve has a plurality of rigid grippers seated therein which extend flush with an inner surface thereof for gripping the drill pipe to facilitate concomitant rotation of the sleeve and rotary housing therewith.  The circulating pumps have a heat exchanger connected thereto for cooling the hydraulic fluid which reduces the internal temperature of the rotary blowout preventer to extend the operating life of various bearing and seal assemblies commonly found therein.  Filters are provided to remove foreign particulate matter dislodged from the outer casing by the circulating hydraulic fluid.

Granted: 2001-03-27
Abstract: The proposed method includes the following steps: forming at least one material input zone on the surface of electrolyte, disposing a working tool in the input zone to push the material into the melt of electrolyte, imparting mechanical oscillations and translatory motions to the working tool in the direction towards the electrolyte and back therefrom with the length of said motions being within the range of values from about 10.0 to about 120.0 sec. The method method further includes transporting material into the input zone and forming some layer in the material input zone, and after accumulation of a sufficient amount of said material the latter enters into contact with the working tool. The aforesaid steps increase the capacity of the material input zone and reduce power expenditures on the input of material into the electrolyte.

Title: Circuit arrangement for the production of voltage pulse sequences, in particular for the operation of dielectrically impeded discharges
Inventor: HUBER ANDREAS
IPC: H05B41/34
Filed: 1996-12-18
Granted: 2004-10-12
Abstract: Circuit arrangement for the production of voltage pulse sequences, in particular for the operation of dielectrically impeded discharges.        An electrical circuit arrangement for the production of voltage pulse sequences, in particular for the operation of dielectrically impeded discharges, has a charging circuit, with a charging capacitor (C2), fed with an input voltage (U x), a discharge and pulse circuit with a fast controllable switch, in particular with an IGBT (T1), which is connected to a clocked drive circuit (A), and a pulse transformer (TR1) with a load (L) connected thereto, and a feedback circuit with a feedback rectifier, for example semiconductor diodes (D3-D4) and a feedback energy accumulation circuit, for example a buffer capacitor (C1) connected in parallel with the input of the charging circuit. During each phase in which the IGBT is on, the electrical energy stored in the charging capacitor (C2) is transferred via the pulse transformer (TR1) to the load (L). The energy reflected from the load (L) and the pulse transformer (TR1) passes through the feedback diodes (D3-D5), is fed to the feedback point (R) and is received by the buffer capacitor (C1). During the reflection phases, the potential of the secondary winding is thereby clamped to the potential of the input voltage (U x). Furthermore, the energy fed back is in this way used as a contribution for the charging phases of the charging capacitor (C2).

Title: Signal-processing method and device for substituting non-correctable blocks in a receiver for block-coded audio signals
Inventor: LECKSCHAT DIETER
IPC: G10L19/005
Filed: 1995-08-01
Granted: 2002-06-25
Abstract: In order to improve the transmission quality of block-coded audio signals in audio communications sys- tems, for example in DECT cordless telephones, when transmission errors occur, in such a manner that the requirement for computation power and thus the costs are minimal and no additional delay occurs to the audio signal to be transmitted, pauses in the audio signal which are caused by transmission errors are replaced by a pause-specific substitution signal which is generated in advance. In the simplest case, the substitution signal is generated by the signal section which immediately pre- cedes a given signal section of the audio signal being buffer-stored and, if the given signal section is disturbed, being inserted into the gap which is produced by the disturbance.

Abstract: ABSTRACT A pulverized fuel combustion burner applied to a boiler of a thermal power plant or chemical plant, a furnace of a chemical industry or the like is provided in which, even if the injection direction of the primary air nozzle changes upward or downward, a proper concentration distribution of the mixed flow of the pulverized fuel and the earner air can be obtained at the exit plane of the furnace side wall and leakage of a portion of the combustion auxiliary air into the furnace is not caused. The pulverized fuel combustion burner comprised a rich/lean flow separator provided at or near the jointed portion between the primary air nozzle and the pulverized fuel supply pipe. The rich/lean flow separator is enabled to change its direction in response to or independently of a change in an injection direction of the primary air nozzle. Thus, the rich/lean flow separator follows the change of the direction of the injection of the primary air nozzle and the mixed flow so separated rich and lean can be injected in the same direction as the primary air nozzle without any biasing.
