Title: Outils de rectification a revetement et procedes de preparation desdits outils
Inventor: JULIEN D LYNN
IPC: C23C14/06
Filed: 1992-08-17
Abstract: Un revêtement de nitrure de titane (ou bien d'un alliage ou d'un métal équivalents) est appliqué sur la surface abrasive d'outils classiques constitués de nitrure de bore cubique et de diamant, selon le procédé de dépôt en phase gazeuse par procédé physique, à des températures plus basses que la température de revenu du métal constituant le noyau et plus basses que la température à laquelle la différence entre les coefficients de dilatation du substrat et de l'abrasif entraînent des contraintes qui endommagent leur liaison. Dans ces conditions, le procédé n'affecte pas l'intégrité du noyau d'acier de l'outil de rectification, et le nitrure de titane, ou bien un revêtement équivalent, stabilise et renforce la liaison existante entre le nitrure de boron cubique, ou le diamant, et le noyau, ce qui permet d'obtenir un outil de rectification d'une plus grande efficacité et d'une durée de vie plus longue.

Abstract: A blood pressure monitoring device (2) comprises an integrally formed, substantially unitary manifold (6) has an air inlet port (14) for communicating with an air pump (4), and two cuff ports (18,24), one to be coupled to a blood pressure cuff (8), the other to be used to sample ambient pressure. The manifold further includes a transducer port (26) for communicating with a pressure transducer (10) and four valve seats (66,68), for receiving high- and low-pressure distribution valves (20,22), and high- and low-pressure relief valves (16,20). The high-pressure and low-pressure relief valves (16,30), which are seated in the manifold (6) are actuated only in emergency situations arising when the pressure in the manifold exceeds a predetermined limit. The distribution valves (20,22) utilize solenoids (52), and therefore have two positions, namely, energized and de-energized. When the solenoids (52) are energized, communication is allowed between a first plenum chamber (12) and the cuff ports (18,24), the first plenum chamber also being in communication with the high-pressure relief valve (16) and the air inlet port (14). Simultaneously, communication between the cuff ports (18,24) and atmosphere is sealed off. In contrast, when the solenoids are in their de-energized position, communication between the first plenum chamber and the cuff ports is sealed off, allowing communication between the cuff ports and atmosphere. The manifold further includes a second plenum chamber (28) that is in communication with a low-pressure relief valve (30) and a second cuff port, and is selectively in communication with the first plenum chamber, the two plenum chambers (12,28) being in communication when the low-pressure distribution valve (22) is in an energized position.

Abstract: The object of the invention was to provide a method for the dismantling and mounting of single-span and multi-span bridges in the form of a continuous girder or a series of individual girders, in which the material expense and time required for the dismantling of the old superstructure can be significantly reduced without impairing the traffic routes passing over them. Furthermore, it is the object of the invention to provide an apparatus necessary for carrying out the dismantling of the old superstructure. As a solution, it is proposed that, in order to form supports for longitudinal displacement paths 6 for the dismantling of the old superstructure 3, girder bundles 2 consisting of the girders 9 of the main supporting structure of the new superstructure are employed which, after the dismantling of the old superstructure, are separated into individual girders by transverse displacement, and these are mounted in their final position as main girders. From the girders 9 of the main supporting structure of the new superstructure there are formed girder bundles 2 which are arranged on both sides of the old superstructure 3, in the bridge longitudinal direction, on prefabricated foundations 4 with rules 10. Displacement paths 6 in the form of sleeper tracks with rolling carriages 14 are laid onto the girder bundles 2, and consoles 7 are fixed to the old superstructure 3. By means of load-lifting means 15 engaging on the consoles 7, the old superstructure 3 is raised and moved in the bridge longitudinal direction. The invention is applicable in composite bridge construction. <IMAGE>

Abstract: A magnetic recording medium comprises a substrate on which is a coating comprising at least one layer comprising hard particles and soft load bearing particles. The soft load bearing particles have a hardness less than that of the hard particles (preferably a Vickers hardness of less than 700 kg/mm² or a Moh's hardness less than 7.5), average diameters greater than 0.1 times the thickness of the layer in which they reside plus any layers that may lie between that layer and a contact recording head, and are present at a volume loading of less than 15% (measured against the total coating volume). The hard particles may be the magnetic pigment particles themselves, if they are present in the same layer as the soft load bearing particles. The medium is manufactured by a process that involves distinct dispersions of materials, only one of which dispersions comprises the soft load bearing particles. The dispersions are then combined to produce a material for coating. The finished media exhibit improved "runnability" performance,  i.e ., reduced static friction between the medium and a contact head, as well as reduced dynamic friction over extended (at least 48 hours) constant motion, increased durability, and decreased electromagnetic signal modulation. In the form of a diskette, the medium exhibits reduced starting torque.

Abstract: Method for the efficient polling of queues of unknown length, by the generation of a polling table. Using one or more queue characteristic values for the various queues, the polling sequence of the various queues is calculated. Using one or more of said queue characteristic values, the time duration for polling each queue is calculated, taking a margin factor parameter into consideration. Using the polling times per queue obtained in this way and the switchover time, the relative polling time instants are calculated. Finally, using a start time parameter, the absolute polling time instants are calculated and written into the polling table. The polling table can be calculated once at initialisation or else recalculated periodically. 
     The method is in particular applicable when using a mediation (2) to poll call records from subscriber exchanges (1) for the purpose of providing detailed invoices by a "billing centre" (3).

Abstract: A surface emitting type of light emitting devices has a narrow emanating region near the front surface. A spherical lens is fixed on the front surface or rear surface for converging light beams to a core of an optical fiber. Prior devices determined the position of the spherical lens by forming a concavity or a set of protrusions on the rear surface. Two wafer processes were required to form the concavity or protrusions. Two wafer processes on both surfaces induced not a little positioning error. 
     This invention does not form concavities nor protrusions on the rear surface. The rear surface is ground and left flat. Second electrode is formed on the rear surface, not hindering light to emit through. The center of the emanating region is determined by supplying current to the device and illuminating the emanating region. The emanating pattern is observed by a TV camera connected to a computer. The center of the emanating region is detected by image processing of the illuminated pattern. The position of the center is memorized. Adhesive is supplied to the rear surface of the chip. A spherical lens is carried to a spot of the memorized coordinate. The adhesive is hardened in a moment to fix the lens at the spot.

Abstract: The method involves the steps of establishing on request of a first DTE to a second remote DTE a set of n independent digital communication channels between said terminal adapters, and determining during an initialization phase the relationship between the slot of each channel used for the building of said aggregation superchannel and the chronologic order of the establishment of the considered slot. Then, the high-rate data flow is splitted and each byte is transmitted through the independent digital channels in accordance with the chronologic order which was previously assigned to each of the said channels. In the remote DTE, each byte of the splitted high-rate data flow are received through the different independent digital channels and are loaded in a single memory at an address which is computed from the following formula: 
 
       A(n)= A(n-1) + n           
 
 Where A(n-1) corresponds to the address in which is stored the preceding byte conveyed through the considered channel, and n corresponds to the number of digital channels established. Therefore, each channel works independently and there is no need to measure any delay between the channels. The memory storage will contain at continuous addresses the high-rate data flow. Applied to a ISDN, fractional T1 or multi-channel E1, the method provides an aggregate link operating a nx64 kpbs.

Abstract: Disclosed is a method of removing propylene carbonate developer or stripper fumes arising from the photolithographic circuitization of electronic circuit packages. In the fabrication of electronic circuit packages, photoresist is deposited on the circuit package substrate. The photoresist is imaged and developed, the package substrate circuitized, and the remaining photoresist is stripped. Propylenecarbonate is used as either or both of the developer or the stripper. Even though it has a low vapor pressure and a high boiling point, the nature of the photolithographic process is such that gaseous propylenecarbonate is evolved during fabrication of the electronic circuit package. The process includes the subsequent step of removing the propylene carbonate bearing gas, as air, from the process, and passing the propylene carbonate bearing gas (12) through an aqueous alkaline liquid (13) in a scrubber (21) to scrub the propylene carbonate from the gas. The scrubbed air (15), substantially free of carbonate, is recovered from the process.
