Granted: 1996-01-10
Abstract: The invention relates to a telephone system with which a connection between two subscribers can be established, at least one of them being a mobile subscriber. The system includes a paging network composed of one or several extensive paging ranges, each of them having a paging transmitter (Hl,H2) of its own, a small cellular network with an exchange and a plurality of base stations (T), and mobile telephones with which a pager has been integrated. When calling a mobile telephone, the transmitter of the paging range in which the telephone is known or assumed to be transmits a paging message to the telephone, whereby, when the telephone is in the neighbourhood of the base station, the exchange of the cellular network establishes immediately a connection between the subscribers. No paging calls are lost because they are stored in the exchange of the cellular network, and on an appropriate occasion the pager of the telephone and the exchange compare the paging messages stored in the memories. In the disclosed system the call can be transmitted from one base station to another during the call (handover).

Abstract: Dans le cas d'un embrayage (6) servant au blocage du différentiel d'un véhicule, une moitié mobile (60) dudit embrayage (6) est amenée par glissement indirectement par l'intermédiaire d'un manchon coulissant (70) et d'éléments intermédiaires (77) dans le sens de la fermeture. Ensuite, le manchon coulissant (70) maintient, au moyen d'une surface de blocage (74), les éléments intermédiaires (77) immobiles dans une position de blocage entre une surface d'appui (64) de la moitié mobile (60) et une surface de retenue fixe axialement (4). Des faces d'entraînement (52, 62) de dents accoupleuses (51, 61) d'une moitié fixe axialement (50) et de la moitié mobile (60) forment, avec le sens de l'axe, un angle de déflexion (55). La surface d'appui (64) et la surface de retenue (4) forment un angle de coin (65). La surface de blocage (74) du manchon coulissant (70) est inclinée par rapport au sens de l'axe avec un faible angle de desserrage (75). Pour libérer l'embrayage (6), le manchon coulissant (70) est retiré. Un couple génère, grâce à l'angle de déflexion (55), une force de déflexion axiale libérant l'embrayage (6). En même temps, les angles de coin (65) font sortir les éléments intermédiaires (77) de leur position de blocage. Une faible force de serrage et une faible force de desserrage exercées sur le manchon coulissant (70) sont suffisantes pour maintenir et pour ouvrir l'embrayage (6), même à l'encontre du couple le plus élevé.

Abstract: In previously known two-roller machines, in particular roller presses, which consist of two rollers which are rotatably mounted in a housing, driven in opposite directions and have gearing attached to the drive pins of the rollers, torque supports are provided to receive the reaction moments and are constructed as two-armed lever plates and, on the one hand, are connected securely to the gearing and, on the other hand, are connected in a rotationally movable manner to a torsion shaft via linkages and lever arms. Since in this arrangement the lever plate arms are of equal lengths, in each case only one lifting plate can be arranged on one side of the two-roller machine for reasons of space. However, this entails an increased space requirement. However, according to the invention the arrangement of both torque supports on one side of the two-roller machine and thus a considerable simplification and more compact design of the two-roller machine is achieved in that the lifting plate arms (16, 17) which are connected in a rotationally movable manner to the torsion shaft (13 and 14 respectively) via linkages (9, 10) and lever arms (11, 12) are of unequal lengths.

Abstract: Un procédé permet de produire des pièces en céramique exemptes de fissures ayant une grande section transversale. A cet effet, on moule par injection ou on coule en barbotine un mélange initial de poudre céramique de manière à façonner un article. Le mélange initial de poudre céramique contient un liant et entre 0,1 v/o et 10 v/o de barbes ou de fibres en carbone, en graphite ou en polymère organique à température de fusion ou de décomposition élevée. On chauffe l'article ainsi façonné dans une atmosphère d'azote jusqu'à une température égale à 450 °C, puis dans une atmosphère d'air à une température comprise entre 450 °C et 600 °C afin d'éliminer tout le liant. On chauffe ensuite l'article ainsi obtenu dépourvu de liant à 800 °C pendant une durée suffisante pour éliminer entièrement les barbes ou les fibres de l'article façonné. On renferme l'article dans du verre et on le comprime isostatiquement à chaud à une pression de 30.000 psi afin de condenser l'article jusqu'à environ 99 % de ses dimensions théoriques. L'article ainsi obtenu a une géométrie complexe et une large section transversale mais est dépourvu de fissures nuisibles.

The sludge is dried with addition of heat in a drying chamber (2), the sludge being transported on an endless travelling grate (3) from an inlet opening (8) in the drying chamber (2) to a discharge opening (9) in it. The sludge is deposited on the grate in a plurality of juxtaposed sludge strings (18) by means of an extruder (6), in which the sludge is preheated to almost 100 DEG  C. prior to extrusion. The extruded strings (18) are then heated with such an intensity that the water in the sludge immediately begins to boil, and that a zone of preferably saturated water steam is formed at any rate in the immediate vicinity of the sludge. This provides a light and porous, dried sludge product which is in no way either burnt or scorched, and which constitutes excellent fuel as well as excellent compost. The system has a simple and compact construction and is inexpensive to produce, just as it works at moderate operation costs.

According to one embodiment a confocal interference microscope (100) may be employed to build up an interferogram of surface (123) of object (124) as follows. A portion of the light beam from coherent laser diode (101) is coherently guided to exit (115) and focussed into a diffraction limited spot (125) intersecting surface (123) by high quality lens (122). A portion of the scattered signal light resulting from spot (125) is collected by lens (122) and confocally injected back into exit (115) to be guided back to coupler (108). A second portion of the light beam from diode (101) is coherently guided to end (121) from whence it emerges collimated. This collimated beam termed the reference beam is partially reflected by mirror (126) through end (121) and is guided back to coupler (102) where it interferes with the signal beam. The result of the interference is detected by detector (127) and fed to a computer (128). A portion of the signal light injected into fibre exit (115) is guided to detector (145) which detects the intensity level. This intensity level is fed to a computer (128) and used to control scanner (130) so as to maintain the focus of spot (125) on surface (123). A portion of the reference beam reflected by mirror (126) is injected into single mode fibre (135) and guided coherently to coupler (138) where it interferes with illuminating light guided coherently from laser diode (101) and thence detected by detector (142). The resulting signal is fed to a computer (128). While scanner (130) is moving the exits the computer (128) keeps track of their position by monitoring the interference signal from detector (142).

Abstract: A comprehensive gas filtering unit in which the preferred embodiment includes sheet(s) of flexible, coilable, permeable, carbon impregnated fabric that are spirally wound around a center structure is disclosed. Active gas filtering spacers are optionally employed between the adjacent layers of wound fabric to physically separate same, thus creating air flow channel(s). Further, the active filtering spacers promote pneumatic agitation and pressure differentials. The air path typically is shaped to varying patterns including an outward flow perpendicular to or traversing the layers of the filtering fabric; flow through the actively filtering spacers; and parallel flow along the surfaces of the filtering fabric and the actively filtering spacers, with varying combinations of these patterns repeatedly occurring throughout the gas filtering chamber. Each spacer contains one or more of a variety of types of filtering agents with spacers being employed in combination in the filtering unit, in order to effectively handle a diverse group of contaminant gases. In one embodiment a central manifold structure utilizes airflow infuser wings that facilitate attachment of the fabric. The airflow infuser wings form inlets to the filtering channels and provide structural support for the channels. The infuser wings are strategically positioned around a central air handling impeller wheel that forces air outward through the infuser wings and subsequently into the filtering channels. This direct entry of the air results in minimal resistance to the airflow.

Abstract: A method and apparatus are disclosed for providing an indication relating to certain faults that can occur during data storing operations in an array storage system (14). In connection with providing the indication, a code byte having a number of code bits is appended to data that is stored on storage devices (24aa ... 24ja, ..., 24aN ... 24jN) of the array storage system. When such a fault occurs, predetermined code bits are set to indicate the data operation that was taking place when the fault occurred. In a preferred embodiment, there are two data storing related operations for which predetermined code bits are set when a fault occurs, namely, a data reconstruction operation and a data reassignment operation. Since these operations are typically initiated automatically and are transparent to any host system (10) connected to the array storage system (14), such a fault indication enables the user to determine the identity of the data storing related operation that was in progress when the fault occurred. <IMAGE>
