Granted: 1988-07-05
Abstract: A BRAGG DISTRIBUTED FEEDBACK SURFACE EMITTING LASER Abstract of the Disclosure A surface-emitting, light emitting device has a columnar active region of one direct bandgap semiconductor and an adjacent confining region of higher bandgap semiconductor.  Contacts are made to the active and confining regions and a window is formed in the device in vertical alignment with the active region to permit light emission from the device.  The semiconductors are doped to establish a pn junction within a carrier diffusion length of the heterojunction between the active and confining regions, the pn junction extending the length of the active region.  In use, laser light is emitted along the axis of the columnar active region in response to current passing across the pn junction.  The active region is epitaxially grown with a compositional and refractive index periodicity causing Bragg distributed feedback (DFB) laser operation, the bandgap of the material of the confining region being higher than that of all the layers in the active region.                             -i-

Abstract: Abstract Debit Card An optical information-bearing debit card having servo tracks and calibration works on a recording medium for aligning a reading or writing light beam with a nearby value site area. The medium is an elongated strip of reflective information storage material adhered to a self-supporting card, like a credit card. The value site area may be decremented by the light beam changing the optical characteristics of the recording medium. The servo tracks are lengthwise, parallel to the long dimension of the strip of recording material while the calibration marks are non-continuous marks, aligned in a track parallel to the servo tracks. Tracks and calibration marks are disposed on the card so that the value area can be read bidirectionally starting from either end of the card.

Abstract: Title:          A method of  preparing a stable alcoholic beverage, on the basis of soured milk, having good keeping characteristics. Abstract of the disclosure A method of preparing a stable alcoholic beverage on the basis of soured milk and having good keeping characteristics.     Milk or milk enriched with fat, with a fat content of at least 4% is mixed and homogenized, then eventually heat treated, rehomogenized and pasteurized before being soured by fermen-tation in known manner or by addition of a solution of an edible acid at a temperature below 5°C to a desired pH value.    The resulting product is mixed, if desired, with water or a water-containing liquid and optionally with sugars, fruit juice, fruit concentrate, fruit essence, flavouring agents, colouring agents and/or thickening agents, The mixture is then homogenized in two stages, one at a pressure of between 180 and 250 bar and one at a pressure of between 10 and 80 bar.          The mixture is subjected to a thermal treatment in which it is warmed-up to a temperature of between 45° and 55°C, while keeping the mass in motion and maintaining a temperature difference between the mass and a heating medium of no more than 10°C, and then cooled to a temperature of between 25°     and 35°C, at which temperature the mixture is re-homogenized.          The mass is then subjected to a thermal treatment to thermize, pasteurize or sterilize the product.          Carefully deaerated alcohol is added to the stable soured product, while the mass is kept in rapid motion, optionally in combination with, or followed by the addition of flavour components. The pH of the liquid is adjusted to the value desired for the end product.          Eventually the product is pasteurized or sterilized.

Abstract: ABSTRACT     The extrusion of a tire sidewall or tread and sidewall strip with a white sidewall stripe integrally formed therewith is made possible by an improved, modified preform unit.  The preform unit has a first passageway for the sidewall or tread-sidewall strip that extends from the entrance side through to the exit side of the unit.  The unit is modified to include a second passageway for the white sidewall material that introduces the white material into the stream of the black sidewall material as it passes through the unit.  Upstream of the point where the white side material is introduced, the blockage means interrupts the flow of the black material, creating a void in the stream into which the white material can flow.

Abstract: SYSTEM AND METHOD FOR SKILL ENHANCEMENT       AND BEHAVIOR MODIFICATION                          ABSTRACT OF DISCLOSURE            Structural systems and method are employed including a multiplicity of computers to control the acquisition and enhance-ment of skilled performance or behavior.  Preprocessing computers (8 and 24) each accept signals from any corresponding one of a variety or physiological or other signal transducers either in close proximity to the computer or transmitted to the computer via a telemetering system.  The preprocessing computer calculates a number of different measures of this signal and makes the results known to one or more other computers.  These other or auxiliary computers control prevention of a display of the data for a human observer and perform additional calculations which deter-mine if the processed data is within a predetermined range.  This range may be a function or time and/or other variables.  A measure of the error between the allowed range and the processed data is computed within these auxiliary computers  These results may be used to alter the display.  They are also returned to the pre-processing computer where they may alter the preprocessing calcu-lations.  Alteration of the display and the preprocessing calcula-tions are adapted to improve skilled performance and behavior without the intervention of a human operator other than the user.                       BACKGROUND OF INVENTION          In the past, the introduction of signals which are elec-trical analog of physiological signals into a computer or display has been used primarily for one of three purposes.          (1)  Acquisition of data concerning physiological and/or behavioral responses, possibly to some external stimuli.

Abstract: ABSTRACT OF THE DISCLOSURE    A memory subsystem couples to a bus in common with a central processing unit and processes memory requests received therefrom.  The subsystem includes a number of addressable memory module units or stacks each having a number  of word blocks  of  random  access memory  (RAM) chips arranged in one of  two subsystem configurations and mounted on a single circuit board which connects to the remainder  of  the subsystem through a single word wide  interface.    The  configurations  correspond  to  a common  stack  arrangement  which  provides  double  the normal   amount  of  density and  an  adjacent   stack arrangement of  normal  density.   As a function of  an input density signal, chip select circuits preselect a pair of blocks of RAM chips from a common stack or pair of  adjacent  stacks.     Timing  circuits  generate  a plurality   of   column   address   pulses   which   are selectively applied to the preselected blocks of chips within  an  interval  defined  by  a  row  address  pulse. This results in the read out of a pair of words from the preselected blocks of a single  stack or adjacent stacks  in  tandem  into  a  pair  of  subsystem  data registers.   For  each memory  read request,  the words from each preselected pair of blocks are read out into the  data registers in the  same  sequence  providing a double   fetch   capability   without   any   loss   in performance.

Abstract: ABSTRACT OF THE DISCLOSURE:       In a multilevel modulator for use in modulating an input digital signal of N levels into a multilevel modulated signal, the input digital signal is converted by a code converting unit into a major converted signal for the input digital signal and a minor converted signal corresponding to the major converted signal.  The major converted signal is rearranged into groups each of which consists of a predetermined number of levels smaller than N and which is produced in a time division fashion together with the minor converted signal.  A signal producing unit processes each group to produce a Lee-error correcting code sequence.  Alternatively, major and minor converted signals are produced on quadrature-phase amplitude modulation of a circular signal arrangement of N-levels to divide the circular signal arrangement into a square signal arrangement and the remaining signal arrangement.  In a counterpart multilevel demodulator, an inverse operation is carried out to reproduce the input digital signal.

Abstract: MODULAR CONNECTOR FOR               SECURING TELEPHONE LINE          Abstract of the Disclosure A security modular connector constructed to fit into a conventional jack or receptacle for use in securing a connection in a telephone or computer system, such as for connecting a telephone base unit to a tele-phone line.  The security modular connector differs from a conventional modular connector in that the spring-biased tab which bears on a stop when in electrically-engaged relation with the jack or receptacle is cut off so that it does not protrude through the opening of the latter, thereby denying manual access to the tab.  Furthermore, a flange on the outer end of the security modular con-nector substantially closes the opening in the jack or receptacle when the connector is in engagement with the former.  Thus, unauthorized persons are denyed access to the line.         A special tool enables authorized persons to pry open the security modular connector from the face of the jack or receptacle, and depress the spring-biased tab, releasing the security connector from the jack or receptacle.     -i-

Abstract: Abstract Film Coolant Passages for Cast Hollow Airfoils The external wall of a hollow airfoil for a gas turbine engine has a plurality of longitudinally aligned diffusing coolant passages having their outlets at the outer surface over which a hot gas is intended to flow.  The airfoil external wall also includes a longitudinally extending slot formed in the inner surface thereof.  Each of the coolant passages intersect such longitudinally extending slot to define metering inlets to each passage for receiving coolant fluid from the slot at a controlled rate.  The coolant diffuses as it passes through each passage and exits as a thin film on the external surface of the airfoil.  The slot is cast in the inner surface of the wall at the time of forming the airfoil; and the passages are machined into the wall from outside the airfoil.  Very small, accurate metering areas for each passage can thereby be formed in single-piece hollow airfoils without access to the interior of the airfoil.

Abstract: ABSTRACT OF THE DISCLOSURE     A remotely operable connector having releasably connec-table male and female members.  The male member sealingly engages the female member on connection.  The female member houses radially moveable dogs which may be locked in con-necting engagement in a groove on the male connector by a lock sleeve longitudinally moveable over the dogs.  The sleeve, which is biased to dogs locked position, moves to dogs unlocked position in response to pressure applied to a first inlet and may be retained in dogs locked position by continued application of pressure to a second inlet.  The female connector houses a pressure lock which prevents movement of the lock sleeve from locked position on appli-cation of pressure to the first inlet, if there is pressure in the connector bore.  The connector is unlocked for disconnect when there is no pressure in  the connector bore and pressure is applied through the first inlet, moving the sleeve to dogs unlocked position.  This connector is par-ticularly  useful in a disclosed underwater well wireline servicing system, as as a wellhead connector or lubricator section connector.  The well servicing system provides wire-line well servicing of underwater wells without pollution of surrounding water and for emergency disconnect from the under water wellhead for quick floating service vessel remo-val.
