Title: Parallel optical arithmetic/logic unit
Inventor: FALK R AARON
IPC: G06E1/06
Filed: 1988-02-26
Granted: 1991-05-14
Abstract: Abstract of the Disclosure A parallel optical arithmetic/logic unit has inputs from point-light sources forming a given spatial pattern corresponding to a given separation of point sources.  The spatial pattern is presented to a multiplicity of channels by an optical system formed of linear optical elements.  A static filter is provided in each channel which allows energy to pass when it comes from one spatial pattern but attenuates or diverts energy from all other spatial patterns.  Thus, energy will emerge predominantly from only one channel for each specific spatial pattern separated by a given separation of point sources.  The desired output state of each channel may be detected to indicate the results of an optical arithmetic or logic operation.

Granted: 1991-04-23
Abstract: BELT TRACKING ADJUSTMENT MEANS FOR           BELT TYPE ABRADING MACHINE               ABSTRACT OF THE DISCLOSURE      An improved belt tracking adjustment means for a belt type abrading or other machine having a frame, a drive pulley, an idler pulley and an endless belt trained over the pulleys includes a support member which supports the idler pulley for rotation about an axis fixed relative to the support member.  The support member is itself attached to the frame by a single screw which as a first function supports the member for pivotal movement relative to the frame about the screw axis, which extends parallel to the idler pulley axis, to vary the spacing between the idler and drive pulley axes.  A spring biases the member in the belt tightening direction and the moments imposed on the member by the belt and spring hold one edge of the member against a flat face of the frame to form another hinge or pivot axis between the frame and member.  A second function of the screw is to provide adjustment of the position of the member about this hinge axis to achieve proper tracking of the belt over the pulleys.

Abstract: Abstract A computer controlled machine for forming longitudinally curved tooth bevel and hypoid gears having a minimum number of movable machine axes for setup and operation.  The movable axes include three rectilinear axes (X, Y, and Z) and three rotational axes (T, W and P).  The rectilinear axes are arranged in mutually orthogonal directions.  Two of the rotational axes (T and W) provide for rotating tool (26, 27) and work gear (42, 43), respectively.  The third rotational axis (P) provides for adjusting the relative angular orientations of tool axis (T) and work axis (W).  Pivot axis (P) is positioned with respect to both tool axis (T) and work axis (W) at fixed inclination angles.  A method of operating the computer controlled machine provides for controlling the movable axis (X, Y, Z, T, W, and P) in response to setup and operating parameters of conventional bevel and hypoid gear generating machines.

Granted: 1992-05-05
Abstract: METHOD AND APPARATUS FOR DETERMINING ARTICULATORY PARAMETERS FROM SPEECH DATA     Abstract of the Disclosure A  system  and method for determining  from  continuous speech,  the instantaneous values of a set of  articulatory parameters.   The  continuous speech data is a  sequence  of spectral profiles obtained by spectrally sampling continuous speech.  The spectral samples are presented in sequence to a plurality   of   class  transforms,  each   establishing   a respective speech phoneme class which includes plurality  of speech  phoneme  having similar  spectral  and  articulatory characteristics.   Each  class transform converts  a speech segment  included in its class and contained in  a  spectral sample  into a predetermined set of  articulatory  parameter values.   A  class-discriminating   transform  operates   in parallel  with  the  class transforms to produce  a  set  of probability values, each indicating the probability that the spectral sample being transformed represents a phoneme in  a respective  speech phoneme class.  An array  of  multipliers adjusts the predetermined values of the sets produced by the class  transforms by multiplying the values of each  set  by the  probability value produced for that set by  the  class-discriminating   transform.    The   adjusted   articulatory parameter  value sets are combined by  adding  corresponding elements to produce a set of adjusted articulatory parameter values  indicative  of an articulatory  tract  configuration appropriate for producing the sampled speech.

Granted: 1994-09-06
Abstract: PROCESS FOR TREATMENT OF WATER CONTAINING VOLATILE AND TOXIC COMPOUNDS           ABSTRACT      Water contaminated with at least one volatile compound is treated by air stripping the volatile compound into the gas phase, then removing the volatile compound from the gas phase by contacting it with an aqueous mixture of biolgical solids and powdered adsorbent. The partially-purified water is further treated by a biophysical aerobic process which in turn produces the aqueous mixture of biological solids and powdered adsorbent used to remove the volatile compound from the gas phase. The aqueous mixture of biological solids and powdered adsorbent containing the volatile compound is thichkened and the solids slurry treated by regeneration, preferrably wet air oxidation, to destroy the biological solids and volatile compound as well as regenerate the powdered adsorbent. The regenerated adsorbent may be returned to the biophysical aerobic treatment process.

Abstract: SURGE PROTECTION DEVICE                 Abstract of the Disclosure A surge or transient protection circuit is described which operates in an immediate fail-safe mode of failure.  If an incoming transient exceeds the tran-sient absorption capacity of the circuit, precision fast-blow fuses are immediately opened to remove current from the load to prevent damage to the equipment connected to the transient suppression circuit and to indicate to the user that the transient suppression abi-lities of this circuit have been damaged.  The transient suppression circuit uses silicon transient voltage suppressor components to absorb the fast-rising edge of transients and also uses slower-acting MOV transient absorption devices for the bulk of the overvoltage tran-sient power.   Upon short-circuit failure of any of the suppressor components, the excessive current draw pro-duced thereby results in blowing of the fast-blow fuses.
