Title: Digital system and method for compressing speech signals for storageand transmission
Inventor: JIBBE MAHMOUD K
IPC: G10L19/00
Filed: 1987-04-06
Granted: 1992-09-15
Abstract: DIGITAL SYSTEM AND METHOD FOR COMPRESSING SPEECH SIGNALS FOR STORAGE AND TRANSMISSION            Abstract The system and method of the invention operates upon a serial bit stream of speech encoded data by reading the data in fixed length frames.  Each frame is classified as to whether the frame represents voiced, unvoiced, or a silence condition.  For a voiced frame, the pitches are detected.  The bits of the voiced frame are then compared with the bits of prior received voiced frames, on a pitch basis, so as to detect repetition.  When repetition is detected, the repetition count, the pitch period, and the one set of the repetitive pitch bits are stored ready for transmission.  The compressed data is reconstructed by utilizing a decoder which interprets the stored information and causes reinsertion of the repetitions.

Abstract: Abstract High Pressure Low Heat Rate Phosphoric Acid Fuel Cell Stack The fuel cell stack (18) is a phosphoric acid fuel cell stack which can operate at higher pressures because it does not use steam in the operation of the reformer portion (40).  By being able to operate at higher pressures, the stack displays very low system heat rates and thus higher operating efficiency.  The higher operating pressure also results in improved fuel cell power density and reduced cost.  The stack (18) is cooled by a coolant mixture of air and entrained water droplets comprising cathode exhaust and injected water fog.  During the cooling operation, the water droplets in the coolant mixture are vaporized in the cooling passages (24) of the stack.  The exhaust from the cooling system after being heated is then delivered to an autothermal reformer (40) where it reacts with a raw fuel reactant to produce hydrogen for operating the fuel cells in the stack (18).  The reformer (40) does not require a separate burner to operate properly.

Title: Sewing system
Inventor: OFF JOSEPH W A
IPC: D05B55/14
Filed: 1987-09-15
Granted: 1992-09-22
Abstract: ABSTRACT OF THE DISCLOSURE           A sewing system that is smaller and more simple in construction than the prior art.  The cloth holding means and cloth clamping means are part of a X-Y-Z motion apparatus that is supported solely from the top arm of the sewing system frame.         Because the spaced twin needles of the sewing system will be required to penetrate up to 14 layers of thick cloth in some anticipated applications, consider-able rigidity and stability is imparted to the single needle clamp that supports the two needles by reciproca-ting the needle clamp with two symmetrically spaced needle bars.  This minimizes canting of the needle clamp and bending of the needle bar, thereby assuring more uniform stitch lines and minimizes missed stitches.

Abstract: Improved poly(arylene sulfide) copolymers of meta- and para-dihaloaromatic monomers are prepared by separately reacting the meta- and para- dihaloaromatic monomers with the sulfur source under polymerization conditions.  Preferably, the meta-dihaloaromatic monomer is reacted under polymerization  conditions  prior  to  the  addition  of  the para-dihaloaromatic monomer.  This method avoids the problem of sluggish meta-dihaloaromatic monomer reactivity and produces poly(arylene sulfide) copolymers of reduced melt flow and/or improved polymer quality when compared to poly(arylene sulfide) copolymers prepared by contacting both the meta- and para- dihaloaromatic monomers together initially.

Granted: 1991-05-07
Abstract: Abstract of the Disclosure Positive Keeper Means For Pins of Earthworking Tips The invention relates to a pin retainer assembly having a keeper means for retaining earthworking tips on adapters.  Positive retention of earthworking tips on their adapters by their retaining pins during its work cycle is extremely important from an operational as well as a cost standpoint.  The loss of the tips materially affect productions in addition to the time consuming expense of replacement of repair of the components.  Not only must the tips be adequately retained, they must be capable of quick removal for replacement purposes.  Keeper means for the pin is captured in a recess between a nose of the adapter and a sidewall of the tips and includes a washer slidably disposed on the pin and a resilient retaining ring having a predetermined radial thickness disposed in locking engagement in a groove on the pin and a groove of the washer.  One of the grooves in the pin and the washer has a depth equal to or greater than the predetermined radial thickness of the retaining ring and the other one of the grooves has a depth sufficient to prevent camming of the ring out of the groove and to provide substantially the maximum cross-section width of the ring in shear.  In order to disassemble the pin, the ring must be sheared or the washer (46) fractured.

Abstract: APPARATUS FOR CONTINUOUSLY CONTROLLED EMISSION            OF LIGHT FROM PRISM LIGHT GUIDE               Abstract of the Disclosure A variety of techniques are used to effect continuously controlled emission of light from a light guide.  For example, the light guide may contain a mechanism formed of a substantially non-light absorptive material having a density which varies as a function of the length of the light guide.  The mechanism causes light to escape from the light guide at a rate which varies along the length of the light guide, such that the amount of light escaping, per unit length, along the light guide has a selected distribution of values.  Al-ternatively, the light guide's central path may be non-linear.  As a further alternative, the average cross-sectional dimension of each of the plane segments afore-said may be non-constant.  As yet another alternative, a first portion of the light guide may comprise prism light guide material and the remaining portion may be such that a substantial portion of light incident there-upon is allowed to escape therethrough.

Abstract: Abstract of the Disclosure This invention relates to a method for controlling the torque of a synchronous machine supplied by a frequency converter,  wherein starting from measured variables (iR, is, iT, if) representing the state of the machine the direct axis flux component (?d), the quadrature axis flux component (?q) and the pole angle (.delta.) for the machine are determined, and set values are produced for the flux ( ? set value), excitation current (ifo set value) and current building the torque  (i2 set value). To prevent the "pull out" of the drive in the method of  the invention,  from the determined pole angle  (.delta.)  there is formed, by means of a limiting block for the pole angle, a limited pole angle (.delta.r) that equals the pole angle (.delta.) if the pole angle has an absolute value smaller than a separately adjustable limit (.delta.max), but equals the limit (.delta.max) if the pole angle has an absolute value equal to or greater than the limit (.delta.max), the set value (i2 set value) of the current building the torque, being perpendicular to the direction forming the limited pole angle  (.delta.r) with the direct axis (d) of the rotor, is projected as the set value (ido set value) for the direct stator current and as the set value for the quadrature stator current (iqo set value) and for maintaining the direct flux  (?d)  at a value corresponding to the limited pole angle (.delta.r) and the flux set value (? set value), the set value (ifo set value) for the excitation current is calculated on the basis of the limited pole angle (.delta.r), the flux set value (? set value) and the set value for the direct stator current (ido set value) so that the set value for the excitation current (ifo set value)  compensates for the direct stator set value (ido set value).

Inner and outer yokes    and    have at respective ends inner and outer pole ends    and    which are spaced axially to each other so as to form therebetween magnetic gaps in each of which the adjacent one of the pole plates    is located.  At least one of the inner pole ends    terminates in a pole tip which is positioned transversely outwardly of the adjacent pole plate and extends in the axial direction to a point where it overlies the adjacent pole plate    when the latter is magnetically attracted to the pole tip    such that the inward face of the pole tip    comes into direct facing relation to the lateral edge of the adjacent pole plate    when the pole plate    is attracted to the pole tip   .  Accordingly, it is possible to reduce the physical gap or the magnetic resistance between the pole tip and the adjacent pole plate    in the position away from the pole tip    without reducing the stroke of the core in the axial direction.
