Abstract: ABSTRACT OF THE DISCLOSURE           This invention is directed to a process for the preparation of an organic isocyanate product comprising the step of preparing a heated solution of an alkyl carbamate in a solvent whereby the carbamate is catalytically decomposed into the corresponding organic isocyanate product and alkyl alcohol.  The solvent is an N,N-dialkyl aniline compound which is catalytic with respect to the decomposition rate of the carbamate but unreactive with respect to the organic isocyanate product.  Organic isocyanates are useful chemical intermediates that may be reacted, for example, with polyols to produce polyurethanes.     28,106-F

Abstract: ABSTRACT          A valveless turbine-like bi-chamber rotary steam engine employing two sets of rotor or sealing blades, rotating around separate eccentric points on a stationary mutual crankshaft within a drum-type rotor concentrically mounted within an oblong engine chamber.  The drum-type rotor forms the oblong chamber into two diametrically opposed radial chambers through each of which one set of the rotor or sealing blades pass as the drum rotates.  The two sets of blades move radially through equidistant slots arranged within the drum-type rotor so as to be extended into one of the radial chambers, thus, varying the volume of the respective radial chambers through which they move. Accordingly, the introduction of a pressurized medium through diametrically arranged inlet ports into the radial chambers rotates the blades and the drum.

Abstract: ABSTRACT OF THE DISCLOSURE A method of fastening a first shell to a second shell to form a housing.  The first shell which has a radial wall with a pro-jection adjacent its peripheral surface is positioned in a fixture. A bead on a diaphragm assembly is located in a groove in the projec-tion.  The opened end of an annular wall on the second shell is placed around the bead and peripheral surface.  The second shell is moved toward the first shell until the peripheral surface contacts a stop on the second shell.  Thereafter, the opened end of the second shell is crimped into engagement with the radial wall to hold the peripheral surface in engagement with the stop.  The fixture is rotated while a tool is brought into contact with the annular wall.  The tool deforms the wall by  creating a rib that radially compresses the bead into the groove and seals the housing.

Abstract: ABSTRACT      The parallel application of a plurality of vocal tract filters (12) is utilized in a speech recognition apparatus.  Each of the filters in this bank of filters has a complex Fourier transfer function that is the reciprocal of a particular vocaltract transfer function corresponding to a particular speech sound.    The speech elements identified are phoneme segments of short duration (typically 10 milliseconds), and correspond to phonemes only in the case of time invariant (sustainable) phonemes.  In a preferred embodiment, it is assumed that the bank of inverse filters, when designed to correspond with the sustainable phonemes, is capable also of closely matching (in a piecewise fashion) the time-varying (transitional) phonemes.    The input of each filter in the bank of filters is connected to the speech waveform input (30).  The output of each filter is examined (18) to determine which output has the smallest absolute value.  Generally, the filters are designed so that when a filter channel has the smallest output at a given time, there is usually present at the input of the filter bank at that time the waveform of the sound such filter was designed to detect.    In a preferred embodiment, the apparatus determines (22) which filter's output is minimum in absolute value for the greatest total time over a given short interval of time, and the associated sound is specified as the sound present at the input.

Abstract: Abstract of the Disclosure A   cutting   blade   is   mounted   on   an articulated arm for movement into location adjacent a new core and a free running span of the web on a winding machine.   An  adhesive  strip  is applied to the  new  core  and  then  the  core  is  rotated.   A pressure roller on an opposite side of the web from the new core then urges the web into engagement with the  surface  of  the new rotating  core.   As  the adhesive strip rotates into contact with the moving web,  it  causes  the  web  to  be deflected  into  the knife  which  results  in severing  of  the  web.   The leading  edge  of  the  severed  web  is  maintained adhered to the adhesive strip so that no fold back of the leading edge occurs as the web continues to wind on the new core.

Abstract: ION IMPLANTED MEMORY CELLS FOR HIGH DENSITY RAM           Wen C. Ko Robert L. Berry ABSTRACT      A semiconductor structure is fabricated using a process involving all ion implantation and using only five masks prior to metallization.  A buried contact mask is used to form a buried contact layer (114), an isolation mask is used to form grooves (130a, 130b) in an epitaxial layer of silicon (113), a self-aligned transistor mask is used to form a mask (134a to 134e) to define the areas in which emitters (138a,  140b,  140c) bases (113, 139) and contact regions (140a) are to be formed, a base exclusion mask (135a,b) is provided to exclude certain impurities from being implanted into a region to be formed of one conductivity type,  and a second exclusion mask (137a, 137b) is provided to exclude impurities to be implanted in a region of opposite conductivity type from the prohibited regions of the structure.  The last ion implantation of the device is a two-level implantation to yield a shallow implant which provides good ohmic contact to certain to-be-formed metal contact areas and a deep implant to provide current gain control for the base of the NPN transistors  (Q1'  Q2)     The metal contacts to active regions on the device are formed merely by etching the device to remove a thin oxide (131) over these regions.  A thicker oxide (134a through 134e) overlying all other regions of the device is substantially unaffected by this etching.

Abstract: ABSTRACT OF THE DISCLOSURE        A reconversion device permits a rapid conversion from a semi-automatic operation system to a pump system and vice versa for fixed barrel sporting and defense guns without disassembling the gun.  When the arm is in a condition for semi-automatic operation, the teeth of the two sectors are engaged in the undercut groove in the support in one of the four-snap action engagement positions of the control handle with the ring.  In order to convert the arm in a condition for pump operation it is necessary to rotate the control handle until the teeth are in a register with the two passages of the annular recess in the support having a height larger than that of the remaining recess and to pull the control handle axially thus withdrawing the teeth from the two passages.  The control handle is thus disengaged from the support and can be rotated until it reaches the next snap engagement position with the ring.  The arm is now in a condition for pump operation.
