Abstract: ABSTRACT OF THE DISCLOSURE          A multi therapeutic device for use in therapy.          The device has a reversible motor having an output shaft capable of revolving in opposed directions.  First and second one-way clutches operate for each opposite revolving direction to be alternatively connected with the output shaft.  First and second eccentric rotors are driven by the motor via a one-way clutch.  A vibrator is driven by the first eccentric rotor.  An orbital motion is generated from the motion of the second eccentric rotor.  Vertical dynamic motion can be developed by a device including one or more reciprocating members with one or more dynamic therapy members.  The orbital motion can be changed to a suitable motion for use of, and transmitting the motion to, the vertical dynamic motion device.

Abstract: ABSTRACT OF THE DISCLOSURE:           The invention relates to a process for the production of the alpha-galactosidase (3.2.1.22) enzyme by culturing yeasts of the Saccharomyces cerevisiae genus in a temperature range from 20°C to 40°C. The invention also relates to a process for enzymic hydrolysis of raffinose by alpha-galactosidase (3.2.1.22) from Saccharomyces cerevisiae. Such hydrolysis may take place with the yeast cells being present or also in the presence af enzymic extracts, both as such and enriched. An important advantage of the invention is the high alpha-galactosidasic activity of the selected microorganisms, together with the absence of any inver-tasic activity.

Abstract: ABSTRACT   Hydrodynamic reversing gearing is disclosed, of the kind comprising a hydrodynamic torque converter for each rotary drive direction which, in the counter-braking range as well, if required, can be alternatively engaged and disengaged by filling and draining, and which both appertain to a low speed range, and also comprising a coupling device which can be engaged for traction in an upper speed range.  The invention provides such gearing which allows the most economical hydrodynamic braking operation possible in the preferred travel direction with the aid of a torque converter intended for reverse travel.  The invention is characterised by a brake control device which is designed in such a way that, simultaneously with the engagement of the torque converter intended for the reverse drive direction, it initiates engagement of the coupling device.  In a preferred arrangement the rotary speed ratio between the coupling halves in the coupling device can be set at different values.

Abstract: ABSTRACT OF THE DISCLOSURE High-voltage switchgear includes one or more poly-phase switches, each in its own module, which are opened and closed by respective stored-energy operators. If energy stored in any operator is released by the action of either an electrical sensor or a hand lever to operate its switch, an electric motor-driven facility or a human-manipulated facility restores energy thereto. Release of the stored energy by the hand lever is blocked during an ongoing restoration of the stored energy by either energy-restoring facility. Also, ongoing restoration of the energy by the human-manipulated facility prevents both operation of the motor-driven facility and release of the energy by the electrical sensor. Each operating mechanism may be selectively coupled to and decoupled from its switch regardless of the presence or absence of stored energy in the operator; if energy is stored when decoupling is attempted, facilities permit the safe dissipation thereof, as necessary, without damage to the switch or the operating mechanism. The switch is locked in its extant position before decoupling is achieved and is unlocked when recoupling occurs. Various indicators visually inform of the position (opened, closed) of each switch, the position (switch open, switch closed) and condition (charged, uncharged) of each operator, and the status (coupled, decoupled) of each switch-operator pair.

Abstract: ABSTRACT OF THE DISCLOSURE           A structure and method for providing cooling fluids from a compression section to a turbine section of an axially flow rotary machine is disclosed.          Various construction details and steps of the method enable the machine to minimize the effect that un-scheduled variations in the temperature of the cooling fluids have on operating clearances in the turbine section.  These unscheduled variations may result from changes in ambient temperature and component deterior-ation.  An internal cooling fluid from the discharge region of the rearmost compressor is used to modulate the flow of a second fluid impinged on the exterior of the outer case for controlling the clearance between an array of rotor blades and a coolable stator shroud spaced radially outwardly of the rotor blades.          In one embodiment, a valve for modulating the flow of the second fluid has at least one thermostatic bi-metallic spring for transducing a change in temperature into a displacement.  The displacement changes the flow area Af between a valve head and a conical seat in the conduit for the second fluid through the valve.

Abstract: ABSTRACT OF THE DISCLOSURE        A low frequency loudspeaker apparatus includes a folded exponential horn which is divided to provide a bifurcated curved sound path from at least one electroacoustic transducer that is positioned at the throat of the horn to a volume into which sound waves are radiated that is located at the bifurcated mouth of the  horn.  The mean length of the folded exponential horn is such that, at an exponential rate of expansion between the throat and the bifurcated mouth, the area of the mouth is adequate for reproduction of low frequencies in the audible range.  An illustrative embodiment of the low frequency loudspeaker apparatus has an effective low end cut-off frequency of 38 Hz. and affords 99 dB SPL output at three meters with one watt input which correponds to about 20% efficiency measured in free space.  Presence of a single boundary surface, such as a stage floor adjacent the mouth of the folded exponential horn, improves amplitude response by 3 to 6 dB.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a digital phase locked loop circuit, particularly to such a circuit which realizes accurately digital phase locked loop pull-in operation at a high speed and with a simplified circuit structure. In the present invention, in order to obtain a phase difference between a single frequency signal and the digital phase locked loop clock signal obtained by dividing the specified frequency signal with dividing counter, such phase dif-ference is obtained in accordance with the signs, absolute values and amplitude ratio of two adjacent sample values taken from the single frequency signal at two points of said digital phase locked loop clock signal corresponding to a phase difference of .pi./2 radians of said single frequency signal.  A fast pull-in of the digital phase locked loop is realized by setting a value in the dividing counter corresponding to the obtained phase difference.
