Abstract: In an ultrahigh purity sealed gas valve of the Y-type having a bellows located in a stem bore, a second seat is provided so that the seat seal engages the second seat to seal off the space within the bonnet tube and the bellows from communicating with the gas flow path, thereby preventing contaminating particles from the bellows from entering the gas system and also decreasing the dead space presented to the closed gas system by the valve. A purge port is located between the open and closed positions of the loseat seal thereby permitting purging gas to bathe the sealing members and the bellows in both positions.

Abstract: A method for synchronizing the dispatching of tasks from a CPU-based first multitasking operating system (OS) with threads of function calls opportunistically dispatched from a CPU-based second multitasking operating system. The second OS includes a set of callable resources. In the method, a task becomes bound to a thread for the duration of that thread's ownership of a callable resource from the second OS. Also, a thread becomes available on a work queue of threads for binding to a task only if the thread owns exactly one resource. After execution, the function is eliminated from the thread and ownership of that resource is relinquished and passed to the next thread queued on that resource. A task can remain bound to the same thread if there are no other threads asserting ownership to the next resource being called by the original thread. With contention, however, the task relinquishes the thread and becomes bound to another thread on the work queue.

Abstract: Bei einem optischen Übertragungssystem mit einem faseroptischen Verstärker (10), der einen wellenlängenselektiven faseroptischen Koppler (12) zum Einkoppeln von Pumplicht in das verstärkende Faserstück (11) enthält, wird erfindungsgemäß ein zusätzliches optisches Signal, z.B. aus einem Dienstkanal, vom Ort des faseroptischen Verstärkers (10) in die eine oder andere Übertragungsrichtung übertragen, in dem es dazu verwendet wird, das Pumplicht zu modulieren. Da das Pumplicht im verstärkenden Faserstück (11) nicht vollständig absorbiert wird, gelangt ein ausreichender Anteil aus dem Faserstück (11) in den Lichtwellenleiter (15) des optischen Übertragungssystems und läuft über diesen weiter zum Endpunkt (A) des Übertragungssystems. Dort wird es ausgekoppelt, auf einen optischen Empfänger (17) geleitet, aus dessen Ausgangssignal das übertragene Zusatzsignal durch Demodulation schließlich wieder gewonnen wird. Damit die Modulation der Pumplicht-Quelle die Verstärkung des verstärkenden Faserstücks (11) nicht moduliert, wird das Zusatzsignal zunächst einer Trägerschwingung mit ausreichend hoher Trägerfrequenz aufmoduliert, und mit dem dadurch entstehenden Modulationssignal wird die Pumplicht-Quelle (13) moduliert. <IMAGE>

Abstract: A pair of waveforms in quadrature relation, or otherwise phase related, are generated from a single direct digital synthesizer employing a single wave lookup table memory. Successive addresses are applied to the memory representing the desired phase difference between the two waveforms plus a fractional part of the increment desired between successive samples along the waveforms. Samples are selected for reconstructing the two respective waveforms by dividing down the sampling clock and providing timing signals therefrom coincident with the correct samples.

Abstract: Method for remotely heating a polymeric material to a selected temperature in which particulate ferromagnetic material (3) having a Curie temperature corresponding to the selected heating temperature is dispersed throughout the polymeric material to form a composite, and microwave energy is applied to the resulting composite. Preferably, the particulate ferromagnetic material comprises only about 2 percent of the total composite by weight. The polymeric material may be compliant, thermosettable plastic, and the Curie temperature of the particulate ferromagnetic material dispersed therein may advantageously be above the curing temperature of the polymer, such that a beam (13) of microwave energy may be used to remotely join surfaces or construct joints in composite structures.

Abstract: In a known control device of the generic type, the set-point adjuster (30) of the gas control valve (32) detects only the volume flow of the combustion air but not its temperature. This can lead to a reduction in the combustion quality, if the temperature of the combustion air deviates significantly from a normal value used as a basis in the design of the control device. As a result of the further function, assigned to the set-point adjuster (30) of the gas control valve (32), of detection of the temperature of the combustion air and temperature-dependent control of the set-point, it can be simply achieved that, at all temperatures occurring in practice of the combustion air within a predetermined capacity range of the gas burner (20), the ratio of air mass to gas mass and thus the excess air can be kept virtually constant. Preferred area of application is control devices for premix-type burners in gas-fired water heaters. <IMAGE>

Abstract: A bus interface employs a bus extender for connecting an auxiliary bus to a single port on a main bus in such a way as to interconnect one or more host computers on the main bus to one or more peripheral devices on the auxiliary bus. The bus extender employs a transceiver coupled to the main bus, another coupled to the auxiliary bus, and signal transfer and logic circuitry passing signals between and controlling the operation of the transceivers. The circuitry also performs all address translation necessary for inter-bus communication. Once communication links have been established with the designated devices on the other bus, the extender sends message data signals received over the one bus directly onto the other bus without modification. Since the interface can comply with SCSI standards, any of a variety of types of commercially available peripheral devices having controllers complying with those standards can be supported on the auxiliary bus.

Abstract: The process serves for the preparation of a low-calorie dietary fibre-rich bread dough and palatable bread. To a bread dough made of wheat flour is made an addition of a vegetable protein at 2 to 15% by weight of the bread dough and a mixture, at 15 to 25% of the wheat flour weight, made of a dietary fibre-rich flour. Furthermore, water is additionally added to the dough at 15 to 25% of the wheat flour weight, the dough is intensively kneaded for 15 minutes and then baked for a period of 30 to 60 minutes at a temperature from 200 to 240. The bread prepared in this manner has about 30% fewer calories than conventional bread. However, the reduced calorie content has no adverse effect on the flavour of the bread which can be produced easily and inexpensively.

Abstract: A corrosion-resistant and environmentally stable ternary compound is disclosed consisting of stoichiometric copper silicide (Cu₃Si), containing chromium (Cr) in the range from about 1 to 10 atomic percent, which is corrosion-resistant and environmentally stable, and thus, among other applications, is a suitable material for use as contacts and interconnects to semiconductor devices. The Cr may be added to the Cu, by co-deposition or sequentially, at the time of the deposition of the Cu onto a clean Si substrate at low temperature. The substrate may be preheated or upon receiving the deposited layer is heated to a temperature in the range of 175 to 400°C to uniformly distribute the Cr throughout the silicide layer formed on the substrate surface. The resulting ternary compound has the Cr atoms dispersed evenly through the Cu₃Si lattice which apparently suppresses the oxidation behaviour of the compound. Other refractory transition elements, e.g., Ni, Co, Fe, and Nb, and combinations thereof, may be added to or substituted for the Cr but give less effective results. Also, the substrate may be either of Si or  Si     x    Ge  1- x    alloy to achieve the improved compound.
