Abstract: ABSTRACT OF THE DISCLOSURE    The activity of a microbiologically active material is measured by suspending the material in a liquid medium capable of forming a gel.   The resultant suspension is formed into small liquid droplets, which droplets are caused to gel,  The gel microdroplets (GMDs) are treated to effect desirable alteration of the microbiologically active material and the amount of metabolites or reaction products of the desired alteration within each gel droplet is measured   Alternatively, incubation is carried out such that each GMD initially containing one cell contains many, a microcolony, which can be tested for desirable properties while retaining sufficient viable cells for growth and harvesting and for further testing and/or production.

Abstract: ABSTRACT OF THE DISCLOSURE      An anti-lock braking system for a four-wheel vechicle having a pair of left and right front wheels and a pair of left and right rear wheels in which one pair of wheels carries a greater load than the other, the system comprising a first braking pressure regulator operative to simultaneously reduce the braking pressures in a pair of wheel cylinders of the left and right front wheels in response to an anti-lock control pressure for the front wheels and a second braking pressure regulator operative to simultaneously reduce the braking pressures in a pair of wheel cylinders of the left and right rear wheels in response to an anti-lock control pressure for the rear wheels.  A late-period operation type anti-lock control pressure supply device is associated with the pair of left and right wheels carrying the greater load to supply the anti-lock control pressure to the corresponding regulator upon detection of locking of a wheel later than the other in the pair of left and right wheels carrying the greater load.  An early-period operation type anti-lock control pressure supply device is associated with the pair of left and right wheels carrying the lesser load to supply the anti-lock control pressure to the corresponding regulator upon detection of locking of at least one of the wheels in the pair of left and right wheels carrying the lesser load.  A dual hydraulic circuit is formed in which the wheel cylinders of the right front wheel and the left rear wheel are connected together by a first hydraulic system and the wheel cylinder of the left front wheel and the wheel cylinder of the right rear wheel are connected together in a second hydraulic system.

Abstract: Cardiac valvular prosthesis of mechanical type consisting of a sewing ring welded to a housing orifice where, in the absence of pins or hinges, two leaflets, preferably provided with a slight curvature, are free to move with both rotational and translational movement. This is achieved through suitable metal structures, able both to permit the correct opening and closing of the leaflets (i.e. to act as a rotation fulcrum) and to guarantee the guidance and the right positioning of the leaflets (i.e. to exert a constraint). The "rotation fulcrum" and the "constraint" structures can be separate and independent, or can form part of one structure devoid of discontinuity.

Abstract: APPARATUS AND METHOD FOR DETERMINING READ HEAD POSITION              ABSTRACT OF THE DISCLOSURE           A system is described for determining the position of a magnetic read head relative to the center of a selected data tragic on a magnetic recording medium moving with respect to the read head.  Tracking signals of equal frequency, but out of phase a predetermined fixed amount, are recorded on adjacent data tracks.  The tracking signal frequency is selected to be a long enough wavelength such that a single read head positioned over a selected data track also detects the tracking signal recorded on adjacent data tracks. A phase comparator compares the phase of the tracking signal detected by the read head with respect to the phase of a reference signal of equal frequency, and a resultant signal is generated which is indicative of any deviation of the read head from the center of the selected track.

Abstract: ABSTRACT OF THE INVENTION           An integrated radio location and communication system comprising a plurality of radio locator-transmitter devices which may be fixed to vehicles and/or carried by persons and which are capable of transmitting the position and identity of the devices to two or more centrally located fixed receiver sites.  The system provides a means of continuously locating and identifying the devices within a city-wide area, or in large subdivisions therein, for example, within a university campus.          Each of the locator-transmitters is continuously phase-locked to the RF carrier of a nearby commercial broadcast station, which station is modified slightly to provide periodic transmission of a transmitter range-tone signal.  An identical phase-locked range-tone signal is likewise generated within each locator-transmitter.  The two or more centrally located fixed receivers detect the carrier range tone signal from the broadcast station and the transmitter range-tone signal from each locator-transmitter device, compares the phase difference between the signals and in response computes the location of each locator-transmitter device.  The system is capable of continuously determining the location of hundreds of thousands of locator-transmitters and communicating automatically the position and identity information to two or more fixed receiver sites.

Abstract: ABSTRACT OF THE DISCLOSURE     A speed reducer having an orbitally driven rotor, mounted for free rotation on a rotor drive wheel driven along a rotary path by a drive shaft,  has a perimeter defined  by  an  epitrochoidal  curve  that  simultaneously engages each of a series of rollers arranged in a circle around the rotor, the number of lobes on the rotor being one less than the number of surrounding rollers. Rotation of the drive shaft causes the rotor to move orbitally and to rotate with a speed reduction equal to the reciprocal of the number of lobes.     The rotor drive wheel is driven by a compensation coupler that prevents radial forces of the rotor and the rotor drive wheel, such as may be generated as a result of inaccuracies in machining, temperature changes, etc., from being transmitted to the drive shaft where they could be translated into large forces. With the present arrange-ment, the drive shaft provides only a rotary thrust on the rotor drive wheel and is shielded from reaction movements of the rotor and rotor drive wheel.     The rotor drive wheel  is driven along an orbital path by a variable-length crank arm that extends into a radial opening in the rotor drive wheel and makes sliding engagement with opposite faces of the radial opening. The driving surfaces that engage the faces of the radial open-ing form,  in a plane perpendicular to the axis of the drive shaft,  arcs of a circle equal in diameter to the width of the radial opening. The radial opening is long enough to permit the rotor drive wheel and the rotor to follow the requisite orbital path. The crank arm includes an expansion slot that divides it into two fingers that embrace opposite sides of the radial opening. For smaller units, the spring quality of the fingers is relied upon to maintain firm engagement between the fingers and the faces of the slot. In larger units, an adjustment screw permits changing the spacing between the fingers to preci-sely fit the width of the crank arm to the width of the radial opening. In either case, the only radial forces on the drive shaft are those generated by the torque of the drive shaft.
