Granted: 1996-05-29
Abstract: Disclosed is an apparatus for switching input port connections to output port connections quickly and dynamically using a new asynchronous approach to resolve contention. The disclosed ALL-NODE (Asynchronous, Low Latency inter-NODE) Switch is self-routing in two cycle times at the same high speed serial rate that data is transferred through the switch. The normal mode of the switch requires absolutely no synchronization amongst any of the input and output ports which interface to the switch. The switch is completely completely void of centrally controlled clocking and any data buffering. Data traverses the switch only encountering three gate delays - on-chip receiver, mux, and off-chip driver. Contention is detected and resolved on chip, and yet the logic implementation is extremely simple and low in gate count, so the switch design is never gate limited. The protocol requires several parallel data lines plus two or three control lines. <IMAGE>

Abstract: In a process and apparatus for inductive hardening of the corrugated surface of a workpiece, in particular the toothing of a gearwheel or sprocket, a uniformly distributed hardness pattern reaching down to a controlled depth is achieved on the teeth by scanning the workpiece surface to be hardened with a single inductive heating coil (12), while the workpiece is taken past the inductive heating coil. A special final heating scanning the workpiece follows a preheating scanning the workpiece, it being possible for the preheating and final heating to be carried out at different controlled speeds. The repeated scanning of the workpiece (W) past a single inductor coil (12) permits the preheating and final heating of workpieces which cannot be taken directly past separate inductor coils in the axial direction, as is the case, for example, with planetary gearwheels having inner ring toothing and a closed end (12), or as is the case with spurgear wheels which have a flange projecting beyond the cylindrical tooth face or a radially projecting shoulder. <IMAGE>

Abstract: In an apparatus having a record mode for recording video or other information signals in successive parallel information tracks on a record tape by means of a plurality of rotary heads repeatedly scanning across said tape and having respective gaps with different azimuth angles, and in which the apparatus is changeable to a playback mode for causing each of said heads to provide a respective output when it is scanning an information track in which information signals have been previously recorded by a head with a gap having the same azimuth angle; clogging of one or more of the head gaps which would prevent further recording is detected, in the playback mode, by switching from one to another of the outputs of the heads during each period required forthe scanning of the tape by each of the heads, detecting the levels of the head outputs during such switching therebetween, and operating a clog indicator when the detected levels of the head outputs are insufficient during the scanning of the tape by each of the heads. In order to avoid a false clog indication, the operation of the clog indicator is inhibited when the usual fixed head does not reproduce control signals in the playback mode, for example, as when there has been no previous recording of information signals on the record tape.

IPC: C22B34/36
Filed: 1986-03-28
Abstract: The scarcity of high grade tungsten ores obliges users to seek to recover it from scrap materials, but drill bits in particular pose especial problems. Existing proposals to use acidic hydrogen peroxide to oxides and solubilize tungsten is extremely inefficient in reagent consumption per unit tungsten recovered. According to the present invention, hydrogen peroxide can be used considerably more efficiently in the extraction of tungsten into an aqueous acidic solution by employing certain promoters which are solid at 50 DEG  C. in the form of fused blocks. These blocks release the promoter slowly into the reaction solution and achieve similar efficiency of use of hydrogen peroxide and acid but at markedly reduced consumption of promoter in comparison with the same promoter added in powder or granular form. Examples of such promoter are hydroxy or amino substituted aromatic carboxylic acids e.g. 2-hydroxybenzoic acid. The promoters can most conveniently be used in a multi-stage tungsten extraction process.

Abstract: PURPOSE: To simplify a starting telegraphic message, to facilitate operations, to reduce power consumption and to eliminate the failure of communication concerning the radio meter-inspecting method for simultaneously inspecting city water meters corresponding to radio waves. CONSTITUTION: When simultaneously inspecting seven meters M1...M5, M8 and M9 among ten meters within a meter-inspectable range A of a meter- inspector 1, two digits of 9th and first digits in an ID number composed of 10 digits or more of respective meters are successively arranged in a meter- inspecting request telegraphic message and transmitted as the digits of ID to be referred to. At each meter where this meter-inspecting request telegraphic message (starting telegraphic message) is received, when those digits are matched with the digits of its own ID to be referred to, the meter-reading values of meters are successively transmitted by radio waves at the intervals of decided delay time for two seconds.  In the telegraphic message, numerals 10, 11, 12...14, 17 and 18 are the numerals of the digits of ID to be referred to for the meters M1...M5, M8 and M9 as meter-inspecting objects.

IPC: G01B9/02
Filed: 1986-04-10
Abstract: @ This invention includes a fiber optic interferometer having a reference arm isolated from a physical parameter being monitored and a sensing arm exposed to the physical parameter being monitored. The sensing arm produces changes in the relative phase of the optical signals propagating in the sensing and reference arms in response to changes in the physical parameter. The sensing and reference signals are combined to produce an interference pattern after the sensing signal has been exposed to the physical parameter being monitored. A frequency shifter changes the frequency of the optical signal input to the interferometer, which produces interference signals for the two frequencies. The optical path difference of the sensing and reference arms for the two frequencies produces phase changes that are in quadrature, which permits the interference signal for one frequency to be expressed as a function of the cosine of the phase change and the interference signal forthe other frequency to be expressed as a function of the sine of the phase change. A demodulation algorithm uses data from the two interference signals to calculate either the tangent or cotangent of the phase angle to determine the phase change in the sensing signal caused by changes in the parameter.
