Title: Annular foreign object search and retrieval apparatus
Inventor: JENS STEPHEN C
IPC: B25J18/06
Filed: 1992-03-03
Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus (10) is for foreign object search and retrieval in annular space (12) around a tube bundle (14) of a nuclear power steam generator (16).  A lance drive (18)  through which a stiff, nonbuckling lance (20) extends has a nose piece (22) extends into handhole (24) of the steam generator (16).  The lance drive (18) is mounted in front of the handhole (24) by a support rail (26) to which the lance drive (18) is mounted.  A lance guide (28) is connected between rear (30) of the lance drive (18) and a lance takeup drum (32). The lance drive (18) has external nosepiece (22) serving as a guide for the stiff, nonbuckling lance (20) as it exits from the lance drive (18).  The nosepiece (22) has a series of roller bearings (36) through which the stiff, nonbuckling lance (20) passes to curve it into the annular space (12).  The stiff, nonbuckling lance (20) consists of a plurality of substantially vertically extending, one piece hosebar supports (38) strung on supporting cables (40) in a manner similar to beads on a string.  Each of the hosebar supports (38) has a convex front surface (42) and a concave rear surface (44).   The convex front surface (42) fits into the concave rear surface (44) of the next adjacent hosebar support  (38).   With the surfaces (42) and (44) engaging in this manner, the stiff,  nonbuckling lance  (20)  has a  substantially increased vertical stiffness, so that it can extend for substantial distances from the nosepiece (22) into the annular space (12) without lateral support.

Title: Process for bidirectional transmission of data
Inventor: SCHROEDER JUERGEN
IPC: H04B10/00
Filed: 1992-04-24
Abstract: ABSTRACT OF THE  DISCLOSURE       A process is indicated for the bidirectional transmission of digital data through a glass fiber, whereby the bits from data to be transmitted are compressed by a factor > 2 into bursts, in packages of equal quantities, without changing the transmission rate. The bursts in one direction of the transmission are sent by an emitter station through a glass fiber to the other station, during the pauses between the bursts in the other transmission direction.  Independent external pulse generators are used at both ends of a glass fiber to determine the transmission rates of the stations.  If the frequencies of the two pulse generators deviate from each other, the bursts of the data flowing at the lower transmission rate are displaced with respect to the bursts of the other flow of data, by the width of one bit of the pertinent continuous flow of data.  The displace-ment of the bursts is communicated to the respective receiver by at least one information bit corresponding to the burst preceding the first burst to be displaced.

Inventor: SHIBATA AKIHITO
IPC: G01C21/30
Filed: 1992-09-14
Abstract: High degree of accuracy of the position of a vehicle can be ensured by maintaining the continuity of the running path of the vehicle and by correcting the vehicle position to a vehicle position measured by a GPS navigation system when an positional deviation occurs due to sensor errors.  Specifically, the vehicle posi-tions are estimated in accordance with signals from sensors for detecting behaviors of the vehicle, and then the vehicle position is shifted onto a designated road having a feature coincident with that of the running path of the vehicle based upon data of the estimated vehicle positions.  Further, the vehicle position is corrected to a position measured by use of a GPS receiver only when the cumulative value of distances of the positional shifts made by a number of cycles in past or in a predetermined running distance range exceeds a predetermined threshold value.

Patent CA-2079060-A1 (CA)
Title: Prestressed brake drum or rotor
Inventor: HESTER LARRY B
IPC: F16D65/12
Filed: 1992-09-24
Abstract: ABSTRACT OF THE DISCLOSURE Uniformly distributed oompressive stresses are induced in the machined surfaces of brake drums and brake rotors. The compressive stresses cancel residual tensile stresses induced in the surfaces by machining operations during fabrication.  Cancellation of the surface tensile stresses delays formation of cracks during brake service use and extends the service life of the brake drum or rotor.  Shot peening is an applicable prestressing process which also imparts a surface roughness that reduces the time required to burnish bake pads to match the shape of the drum or rotor surface.  The reduction of burnishing time reduces the amount of surface cracking caused by surface heating by brake pad high spots as the high spots are ground down.

Filed: 1992-12-18
Abstract: A level of an input luminance signal for a pixel is compared with step values which change stepwise in level in a predetermined range of level, and distribution of the levels of the input luminance signal in the predetermined range of level is represented by a cumulative histogram.  Subsequently, a histogram value is derived from the outline of the cumulative histogram, and a compensation value is produced on the basis of the histogram value, and the compensation value is added to the input luminance signal, and hence a compensated luminance signal is output to control the luminance of a video image.

Title: Process for sulfur recovery from a gaseous stream containing hydrogen sulfide under high pressure
Inventor: HEISEL MICHAEL
IPC: C01B17/04
Filed: 1991-08-09
Abstract: TRANSLATION                 Amended Text from IPEA          Complete Application Text for Transition into the National Phase of the International Patent Application PCT/EP91/01523 A B S T R A C T    The process of this invention offers the possibility of desulfurizing gaseous streams under high pressure with comparatively low expenditure in apparatus but at a high recovery rate.  For this purpose, H2S is catalytically oxidized directly to sulfur in at least one reactor.  With special advantage, two re-actors are used wherein the reactor first in the flow direction, an adiabatically operated reactor without internal cooling, is preferably traversed by the flow from the bottom toward the top, and the reactor that is the second one in the flow direction, a reactor internally cooled with special advantage to a tempera-ture below the sulfur dew point, is traversed by the flow preferably from the top toward the bottom.  Usually, differing catalysts are utilized in the two reactors even though also both catalysts consist essentially of TiO2 and selectively oxidize directly H2S, but not H2 and CO.  In the first reactor without internal cooling, H2S is selectively oxidized directly by the catalyst under high pressure.  The reaction continues in the second, internally cooled reactor, condensed-out sulfur itself acting as a catalyst under the pre-vailing high pressure.  Accordingly, there is no need for regeneration of this reactor from liquid sulfur.          Product sulfur is condensed out and separated from the high-pressure gas stream.  The entire desulfuriza-tion can be still further improved by reduction of the sulfur compounds and/or sulfur vapors to H2S and/or by an adsorption, a chemisorption, or NaOH scrubbing of the H2S, the residual sulfur compounds and/or the sulfur vapor.
