An arrangement is disclosed for recovering from faults in transmission equipment or facilities forming so-called virtual circuits for transmitting packets in a network. Faults are detected in transmission paths associated with a network node and a fault indication is generated for any virtual circuits passing through the node that are affected by the fault. The fault indications are then transmitt...

CONSTITUTION:The pads 21', 23', 24', 25' for measuring and selecting DC characteristics as well as pads 20', 22', 26', 27', 28' for constitution, such as the pads for signals, the pad for a power supply, the pads for biases, etc. are ...

In torches (1) fitted with an electric bulb (lamp) (2) in the shape of a bar or a U, surrounded by a translucent casing (19) and fixed in a socket (4) by means of a cap (3), the socket (4) is sealed, in conjunction with an electrical or electronic ballast (9), in a cap casing (6). The cap casing (6) is connected, at its open front face, to a substantially cylindrical cover (19) enclosing the bulb ...

A feedback signal of an ultrasonic generator (13) employed in a ball bonder (11) is sampled by an analog-to-digital converter (23) under control of a microprocessor (25) to provide a "bond signature" indicative of bond quality. The microprocessor (25) then compares the bond signature to limits representing a good quality bond to provide an indication of a good or failed bond. The indication may be...

A process for making a polyhexamethylene adipamide fiber with a spherulite rating of 1 is disclosed. A molten polymer of polyhexametbylene adipamide is injected with fluorocarbon and subjected to low shear.

Date May 18, 1989.An electrohydraulic system for controlling the gear changing process in a mechanical, automatic gear-box having five gears. The system includes two pairs of electromagnetic valves (57, 58, and 59, 60) which control via pressure-control valves (...

An accelerometer transducer has a base holding a sheet normal to an input axis. The sheet is suspended from the base by a first spring arrangement for oscillatory motion in the way of limited angular excursions about a central axis lying in the sheet. A weight is spring-suspended from the sheet in a manner permitting displacement of the center of gravity of the weight along the input axis. Acceler...

Information(s) to be processed for call set up, as well as for testing and maintenance are supplied to a switching unit. The former are prioritized. A loadability measuring circuit, which compares actual-loading with reference-loading during leveling longer period, short term fluctuations, and continuously sets an adjustment standard related to the inflow of information, which is pre-supplied to a...

SERIAL COMMUNICATIONS CONTROLLER A serial communications controller, adapted for transfer of data to memory in a direct memory access interrupt, generates a status word for each frame of data. To allow for uninterrupted transfer of data to memory from frame to frame, the status words are stored in a FIFO along with word counts corresponding to the frames to allow for subsequent identification of t...

A roll (1) for the press of a paper machine or the like, comprising a substantially rigid cylindrical shell body (2); a resilient layer (3) made of a resilient material such as rubber and positioned on the shell body; and a surface layer (4) positioned on the resilient layer. The resilient layer (3) is formed by fastening profiles (9) made of soft and resilient rubber to the surface of the shell b...

A folded container comprises a rectangular bottom and four folded-out sides. A double walled border flange extends around the periphery of the container parallel to the bottom. The free open edges of the border flange face toward the external surfaces of the sides. The sides are connected by means of folded, triangular corner sections. Two border strips forming portions of the border flange are pr...

The optical disk focussing is detected by observing the interference fringes generated in the far field by the periodicty of the data tracks (5). For this purpose, three diode lasers (21,22,23) and an optical detector (28) are provided. The optical detector (28) consists of two photodiode elements and outputs a signal proportional to focussing error. In order to compensate the phase shift due to t...

INVENTORS: ELMER WEISSHUHN AND HERBERT HOLIK INVENTION: HEADBOX DEVICE FOR A PAPERMAKING MACHINE A fiber stock suspension is directed from a guide device through the nozzle chamber of the headbox device and out of the slice opening thereof onto a papermaking machine. This nozzle chamber comprises at least two zones or sections. The first zone subsequent to the guide device possesses a relatively l...

Appareil (1) pour broyer et mélanger des blocs de matière fibreuse comprenant un récipient (2), un rotor de mélange comprenant un arbre (32) et des pales de mélange (37) supportées sur des organes de support (36) s'étendant radialement par rapport à l'arbre (32), pouvant tourner dans le récipient (2) pour mélanger la matière fibreuse, quatre pales stationnaires (44) coopérant avec le rotor de méla...

A contractible (elastic) and a non-contractible (non-elastic) yarn are knitted together with the contractible yarn floating over at least some needles in a course of knitting. The non-contractible yarn also floats over at least some of the needles where the contractible yarn floats, with the result that a loop pile fabric is produced.

Improved techniques are provided for forming ionized molecules from electrosprayed droplets for analysis by a mass spectrometer. A high voltage is applied to a capillary tube for spraying droplets at substantially atmospheric pressure or above, and the electrosprayed droplets contain sample solute of interest and solvent. The electrosprayed droplets are passed into an ion generating chamber which ...
