Title: Gas turbine drive with devices for branching off compressor air for cooling hot parts
Inventor: HENNECKE DIETMAR
IPC: F02C7/18
Filed: 1986-04-18
Granted: 1990-11-20
Abstract: Abstract In a gas-turbine engine with devices to branch-off compressor air to cool hot components of the turbine, the cooling air is passed along a detour path through components having greater thermal capacity and larger surface areas, to the hot components that are to be cooled.  By this means, when there is an abrupt change in the temperature of the cooling air as, for instance, during the acceleration phase, the cooling air gives up some of its heat content on the detour path on the components, so that the thermal time behaviour of the cooling air is retarded.

Title: Optical fiber connector
Inventor: CANNON THOMAS C JR
IPC: G02B6/36
Filed: 1987-04-14
Granted: 1992-01-14
Abstract: OPTICAL FIBER CONNECTOR            Abstract In an optical fiber connector, an alignment sleeve for holding two conically shaped portions of plugs each of which terminates  an  optical  fiber  includes  two  conically  shaped cavities communicating through a common plane.  A peripheral end portion of at least one end of the sleeve is provided with a notch.  The notch is adapted to receive a key which projects from a plug as the plug is inserted into the sleeve cavity.   This locks the plug in the sleeve and prevents unintended rotation of the plug relative to the sleeve which could abrade opposing end faces of the fibers when a threaded cap in which the plug is mounted is turned into a coupling housing which supports the sleeve and which already has another plug mounted therein.  This connector improves insertion loss and performance repeatability by causing fiber core centroids of optical fibers terminated by plugs received in the housing to be disposed in a common plane which extends radially from a longitudinal axis of the connector.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus and method for ultrasonically bonding a web utilizes ultrasonic bonders having respective anvil and sonotrode components which are synchronously orbited with each other and with the rotation of a rotatable drum which carries the web of material to be bonded.  One of the anvil and sonotrode components is orbited exteriorly of the drum and the other interiorly of the drum and they are brought into facing alignment through openings in the drum to clamp segments of the material therebetween during passage through a bonding segment of the travel path of the web about the drum.  The bonder component orbiting exteriorly of the drum is axially translated away from the anvil along the drum in order to provide clearance for withdrawal of the bonded material from the drum.  In this manner, an ultrasonic bonder may clamp the material at a single location for a large segment of its travel along the rotation path of the drum, thereby attaining a bonding time not limited entirely by the travel speed of the web.

Title: Bipolar transistor with polysilicon stringer base contact
Inventor: VORA MADHUKAR B
IPC: H01L21/60
Filed: 1987-06-30
Granted: 1992-04-14
Abstract: ABSTRACT OF THE DISCLOSURE There is disclosed herein a base and emitter contact structure for a bipolar transistor which is comprised of a polysilicon stripe over an isolation island which stripe extends to a position external to the position of the isolation island and assumes the shape of an emitter contact pad.  The emitter contact stripe has a layer of self aligned silicide formed thereover to lower its resistance, and this silicide is doped with both N and P type impurities one of which is selected to have a higher rate of diffusion than the other.  A layer of self aligned insulating material is formed over the silicide and polysilicon of the emitter contact stripe.  There are anisotropically etched insulating spacers formed on the sides of the emitter contact stripe, and there are silicide base contact stringers formed beside the spacers by anisotropic etching of a layer of doped silicide.  A heat drive in step in the process used to make the structure, also disclosed herein, causes the impurities from the two silicide layers to diffuse into the emitter contact polysilicon and into the epitaxially grown silicon in the isolation island.  An emitter and a base are and the the attendant base-emitter and base-collector junctions are formed because the faster diffusing impurity overtakes the slower diffusing impurity and passes it to thereby form the base region.  The impurities from the base contact stringers also diffuse into the epitaxially grown silicon and their lateral diffusion causes them to link up with the base impurities which have diffused into the epitaxially grown silicon from the silicide over the emitter contact polysilicon.

Abstract: METHOD AND APPARATUS FOR THE AUTOMATIC CALIBRATION OF SIGNALS EMPLOYED IN OXIMETRY                Abstract Under the present invention, R method and apparatus are provided for compensating for the effect temperature variations have on the wavelength of light emitted by the oximeter sensor light sources (40, 42). In pulse oximetry, LEDs (40, 42) are typically employed to expose tissue to light at two different wavelengths. The light illuminating the tissue is received by a detector (38) where signals proportional to the intensity of light are produced. These signalsare then processed by the oximeter circuitry to produce an indication of oxygen saturation. Because current oximetry techniques are dependent upon the wavelengths of light emitted by the LEDs (40, 42), the wavelengths must be known. Even when predetermined combinations of LEDs (40, 42) having relatively precise wavelengths are employed, variations in the wavelength of light emitted may result. Because the sensor (12) may be exposed to a significant range of temperatures while in use, the effect of temperature on thewavelengths may be significant. To compensate for this effect, a temperature sensor (50) is included in the sensor (12) to produce a signal indicative of sensor temperature. This signal is interpreted by the oximeter circuitry including, forexample, a microcomputer (16), where the effect of temperature on wavelength is compensated for. In a preferred arrangement, this compensation takes the form of a computation of an alternative calibration curve from which the oxygen saturation is indicated, given a particular processing of signals from the detector (38).

Abstract: METHOD FOR GENERATING AXIS CONTROL DATA FOR USE IN CONTROLLING A GRINDING MACHINE AND THE LIKE AND SYSTEM THEREFOR          ABSTRACT:         A method  and  apparatus  are  provided  for controlling a cam grinding machine and the like by kinematically modeling (FIGURES 10 through 21) the cam generating geometry of the grinding machine and using the kinematic model to convert cam lift data (FIGURES 3A and 3B), which is related to the desired contour of a cam (12 or 14), to a form which is usable by first and second drive axis controllers  (80 and 76).  The cam lift data is analyzed (110) through the use of a fast fourier transform (FFT)  (116) to thereby obtain FFT coefficients (118) which define the amplitude and frequency content of the cam lift data.   Through a combination of the kinematic model and an inverse FFT procedure,  an  axis  control  function  including  a position  control  function  (Eq.  1  and  Eq.  14)  is determined (128) for each axis.  Dynamic compensation (130)  of each axis is provided for system lags and inertia loads by altering the axis control function as a proportion of the axis velocity and  acceleration (130),  respectively.   For  each  controlled  axis  an independent  vector  and  a  corresponding  dependent vector  containing  axis  control  data  is  generated (132).  During the actual control of first and second drive motors (72, 70) of the grinding machine, posi-tion and velocity feedback signals are generated for each axis by feedback devices  (82, 78).  A master/-slave control arrangement is provided between the two axes wherein the positional feedback signal  (86) from one axis is utilized in the control of the other axis to eliminate time lags between control of the two axes.
