Abstract: ABSTRACT OF THE DISCLOSURE          In complex systems which involve a large amount of interacting electronic equipment, the amount of interconnecting cabling and the attending cross-talk, electromechanical interference and other types of noise pickup become so significant that great expense and skill is required to design a system with satisfactory performance. The system of this invention includes new techniques for data exchange between components of such a complex system with the result that the cross-talk and interference problems are substantially eliminated, while at the same time, the amount of cabling required is reduced to a single communication path which includes only seven conductor pairs. The new system includes a control means for converting parallel digital data from a computer to serial digital data which is trans-mitted to the using device through the communication path where it is then converted to a form suitable for the using device. The system also includes means for converting data received in various forms from the using device into serial digital format for transmission to the control means where it is then converted to a form suitable for the computer.

Abstract: ABSTRACT  OF  THE  DISCLOSURE        An improved method is provided for constructing a stringed instrument of the violin family.  The improvement comprises the steps of: (a) removing said bridge member having said transversely extending feet; (b) increasing the sonority, projection and bombastic tonal qualities of said tone-producing structure, by fitting said instrument with a bridge which includes a pair of symmetrical elongate feet formed integrally therewith, forming the contact between the bridge in directions substantially parallel to the grain of the wood from which said table is formed and shaped, contoured and dimensioned to continuously contact said curved table along lines which are longer than the width of said feet; and (c) maintaining said tone-producing structure and said internal components in their original condition.  This enables one very rapidly and inexpensively to upgrade the tonal qualities of a less expensive instrument to achieve more closely the tonal qualities of a much more expensive instrument.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention relates to a filter device for filtering blood.  Previously, considerable difficulty had been experienced in filtering blood so as to remove gas and solid microemboli therefrom.  Previous filters tend to exhibit substantially decreased flow rates, large pressure drops, and substantial reductions in the effectiveness of the filtration action after the passage of a relatively small amount of blood therethrough.  These and other dis-advantages of the prior art have been overcome according to the present invention wherein an effective, high capacity, low prime volume  high flow rate blood filter is provided.          Filtration is accomplished, according to the present inven-tion in a plurality of filtration stages.  The particle sizes of the blood debris are distributed throughout a plurality of size fractions.  A filtration stage can be provided for each selected size fraction with the coarsest size fraction generally containing all particles with a principal dimension in excess of approximately 100 microns.          At least two other stages are provided in the filter to remove and retain size fractions wherein the particles have a size of less than 90 microns.  The filtering elements which are incorporated in blood filter devices according to the present invention incorporate both depth filter elements and screen filter elements.

Abstract: CONTROLS FOR COMBINED HYDROSTATIC AND MULTIPLE SPEED RANGE TRANSMISSION UNITS WITH AUTOMATIC SPEED CONTROL AND BRAKING FUNCTIONS A drive train includes a hydrostatic transmission unit and a multiple speed range transmission unit arranged in series between a prime mover and a primary output shaft, variable displacement and torque transmitting capacity of the hydrostatic transmission unit being adjusted by hydraulic controls including a speed control valve for developing a differential pressure signal proportional to a desired rate of operation, a modulating valve for regulating the differential pressure signal corresponding to accelerating and decelerating operation of the transmission, a directional control valve for determining the direction of operation of the hydrostatic transmission unit, and a range selector valve for shifting the operating speed range of the multiple speed range transmission as the hydrostatic transmission approaches a limit of displacement, the displacement of the hydrostatic transmission being automatically reset in response to shifting of the multiple speed range transmission. Operating speed limits are automatically established for the drive train by an override speed control valve which manually adjusts the differential pressure signal for reduced torque transmission through the drive train when the prime mover is operating below a minimum speed.  A speed limiting control valve responds to operation of the prime mover above a maximum selected speed for automatically applying a brake within the drive train in order to supplement dynamic braking capacity of the transmission unit, the speed limiting control valve including means producing a feedback signal for resisting manual operation of the override speed control valve in proportion to engagement of the brake within the drive train.

Abstract: ABSTRACT        This invention relates generally to improvements in methods and apparatus for the measurement of blood pressure and heart rate. Conventional blood pressure measurement procedures are prone to a number of signi-ficant deficiencies. For example, the Korotkoff sounds may be of relatively low and difficult to detect ampli-tudes and are often intermixed and easily confused with ambignous signals generated by artifacts and both inter-nal and external noise. In addition, the determination of the end points for the onset and cessation of the Korotkoff sound pulse train is somewhat subjective. The present invention overcomes these deficiencies of the prior art by providing an electronic method and apparatus for automatically determining systolic and diastolic blood pressures and heart rate. Waveform analysis is first performed upon incoming Korotkoff signal waveforms by an analog prescreening subsystem to initially separate true Korotkoff sound signals from a variety of artifact and noise signals and to provide an output pulse stream correctly indicating Korotkoff sound occurrences in the time and blood pressure domain. The output Korotkoff sound pulse stream is then further analyzed by a digital processing subsystem to additionally remove any noise and artifact signals, to modify and certify the resultant data as either reliable or suspect, to determine heart rate and the most probable values for systolic and diastolic blood pressure levels indicated by the signal stream detected during the measurement cycle.
