Title: System for speech recognition
IPC: G09B21/00
Filed: 1979-05-04
Abstract: A system and method for speech recognition provides a means of printing phonemes in response to received speech signals utilizing inexpensive components. The speech signals are inputted into an amplifier which provides negative feedback to normalize the amplitude of the speech signals. The normalized speech signals are delta modulated at a first sampling rate to produce a corresponding first sequence of digital pulses. The negative feedback signal of the amplifier is delta modulated at a second sampling rate to produce a second sequence of digital pulses corresponding to amplitude information of the speech signals. The speech signals are filtered and utilized to produce a digital pulse corresponding to high frequency components of the speech signals having magnitudes in excess of a threshold voltage. A microprocessor contains an algorithm for detecting major slope transitions of the analog speech signals in response to the first sequence of digital signals by detecting information corresponding to presence and absence of predetermined numbers of successive slope reversals in the delta modulator producing the first sequence of digital pulses. The algorithm computes cues from the high frequency digital pulse and the second sequence of pulses. The algorithm computes a plurality of speech waveform characteristic ratios of time intervals between various slope transitions and compares the speech waveform characteristic ratios with a plurality of stored phoneme ratios representing a set of phonemes to detect matching therebetween. The order of comparing is determined on the basis of the cues and a configuration of a phoneme decision tree contained in the algorithm. When a matching occurs, a signal corresponding to the matched phoneme is produced and utilized to cause the phoneme to be printed. In one embodiment of the invention, the speech signals are produced by the earphone of a standard telephone headset.

Title: Process for Finishing Gamma Quinacridone Pigment
IPC: C09B48/00
Filed: 1980-03-25
Abstract: Crude gamma quinacridone is conventionally converted to pigmentary form by salt grinding or grinding in the absence of salt followed by contact of the ground product with an organic liquid. Whilst adequate pigmentary properties may be achieved by these methods, the use of salt or organic liquid is necessary in quite large quantities and this results in problems of disposal and, in the case of salt grinding, loss of pigment yield per unit volume of milling apparatus. The invention enables salt grinding and organic liquid contact to be avoided whilst at the same time providing satisfactory pigment properties by contacting milled quinacridone with an aqueous anionic surfactant or a mixed anionic- nonionic surfactant wherein at least 50% of the surfactant is anionic at a temperature of at least 40 DEG C, the percent by weight of surfactant based on the milled quinacridone being 1- 20% to form a slurry of pigmentary quinacridone and separating the pigmentary quinacridone and liquid in the slurry. The milled quinacridone may be prepared by dry milling the crude gamma quinacridone in the presence of 10-50% by weight of alum based on the crude quinacridone until the 6.5 DEG  2 theta  X-ray diffraction line shows a broadening to 0.40-0.95 degrees at half-maximum intensity.

Title: Indicating power developed by ultrasonic transducer
IPC: G01R17/06
Filed: 1981-05-16
Abstract: In an ultrasonic cleaning system wherein an ultrasonic transducer of low mechanical Q is mounted on or in liquid-containing chamber which is to receive articles to be cleaned an indication of the power developed by the transducer is obtained by including a passive component (Lc), such as a resistance, inductance or capacitance, in series with the transducer and rectifying the voltage (VIc) appearing across the passive component (Lc) to obtain a d.c. signal (Vp) representative of the current in the radiation resistance (RA). As RA is substantially constant over a range of operating conditions the current measurement gives an indication of the power developed by the transducer. The d.c. signal (Vp) representative of the developed transducer power is used to adjust the vibration frequency of the transducer such as to maintain the power level at a predetermined level. <IMAGE>

Title: Apparatus and method for making an indefinite length composite sheet of very large predetermined width from indefinite length sheet stock of relatively small width
IPC: B65H37/04
Filed: 1981-04-03
Abstract: Apparatus and method for making a composite sheet of indefinite length and very large predetermined width from indefinite length sheet stock of relatively small width. Included is a supply roll (10) of relatively narrow indefinite length synthetic rubber sheet material, and a conveyor (12) which feeds out in a horizontal direction past a cutter (14) a sheet of the narrow stock equal in length to the relatively large width of the desired composite sheet stock. After feeding out and cutting the desired length of narrow stock, the cut sheet (11) is transferred laterally by a reciprocating vacuum pick-head (20) to overlap the leading edge thereof with the trailing edge of the preceding laterally shifted cut sheet, effectively augmenting the composite sheet (29). A conveyor (12) advances the composite sheet in the transverse direction to successively locate the lap joints (26) therein at a lap joint pressing station (30) whereat the lap joints (26) are successively pressed to enhance the permanency of the joints. The composite sheet is then fed through a release powder applicator (36) which applies release powder to both sides of the sheet to avoid the composite sheet stock (29), which is uncured, from sticking together when stored in roll form. Downstream of the release powder applicator (36) the composite sheet (29) is fed through a variable tension regulator (38), a sheet slitter (39) which trims the stock to the desired width, and a composite sheet reeling station (40) where it is rolled on a mandrel for subsequent storage and curing. Intermediate the supply roll (10) of narrow length stock and the sheet cutter (14) a station (42) is located for facilitating convenient removal of defective portions of the narrow width supply stock.
