Abstract: ABSTRACT OF THE DISCLOSURE         An EMF detector supplies, from the voltage and the current, the EMF vector in a coordinate system fixed in space, the integral of which is the flux vector.  The integration is carried out in the field oriented coordinate system, in which the EMF vector is transformed by means of a vector rotator.  A rotational component is taken into consideration in the integration by having a first integrator form, from the field parallel EMF component, the magnitude of the flux and having a divider form, from the second EMF component and the magnitude or the flux, the flux frequency, from which frequency an integrator forms simultaneously the flux angle and the angle of rotation for the vector rotator.  An angle control input characterizing the steady state and the angle of rotation, through an angle servo control selectably furnishes the field frequency entered into the second integrator to form, from a magnitude servo control, a feedback signal added to the field parallel EMF component.  Further provided are circuits for taking into account the stray inductance without differentiation and a circuit for stabilization and damping.

Abstract: ABSTRACT OF THE DISCLOSURE      A tube and method for fabricating such tube having enlarged  ends  and  made  of  material  which  can  be strengthened by cold working comprises fabricating a pre-form having the overall configuration of the tube but with increased outside diameters and a decreased length.   The pre-formed tube is cold forged or cold rolled over its entire  length to  reduce  its  outside  diameter  while maintaining  its  inside  diameter  substantially  fixed. This elongates the tube and reduces its cross-sectional area.   Cold working is continued until the final desired dimensions for the tube are reached.   This produces a strengthening  effect  by  cold  working  over  the  entire length of the tube.

Abstract: ABSTRACT OF THE DISCLOSURE     An energy absorbing steering column assembly for a motor vehicle steering wheel.  The column has a tubular jacket supported from the vehicle body by upper and lower sheet metal brackets.  The upper bracket is connected to the body by releasable capsules.  The jacket has a plastic end cap bushing fitted on its forward end.  The bushing is releasably press fitted in a concentric collar portion of the lower bracket.  Under predetermined impact loading on the steering wheel and column assembly, the capsules release the upper bracket allowing the column to be guided forward axially causing radial tabs on the bushing to be sheared-off in a first level energy absorption.  Continued travel of the column assembly in a controlled lateral path provides second higher level energy absorption wherein the lower bracket is deformed in a controlled manner.

Abstract: ABSTRACT          The invention concerns a method and an apparatus for improving the grinding result of a pressure chamber grinder. The finely divided material to be ground is fed by means of a mechanical feeder device into a pressurized equalizing tank, the material, which may have been clodded in the equalizing tank, is made loose by means of a rotor, and the material that was made loose in this way is transferred into a pre-grinder, wherein several grinding-gas jets are applied to the material to be ground so that the material to be ground is fluidized.  The fluidized material-gas flow is passed into a bisecting device, wherein it is divided into two component flows of equivalent magnitude and composition.  Each component flow is passed into the main grinding chamber through a long accelerating nozzle of its own, which said nozzle is directed so that a collision zone for the two component flows is formed in the centre point of the said main grinding chamber.  The invention is characterized in that a solid-gas mixture ground in the main grinder chamber is passed through an acceleration tube into a free-flow grinder so as to reach a final product of steeper particle distribution, whereby grinding gas is passed into the said free-flow grinder through substantially tangentially directed grinding-gas nozzles, whereby the material-gas flow fed at a high velocity into a free-flow grinder is brought into a rapid circulatory movement so that, by the effect of centrifugal force, coarser material particles stay in this grinder longer and are ground more thoroughly than finer particles.

Abstract: Abstract of the Invention A control circuit for a reversible D.C. window drive motor that allows for one touch operations of the motor to automatically lower the associated window to its full down position following a relatively short actuation of the control switch in the "DOWN" position.  Subsequent actuation and release of the control switch will cause interruption and inhibit the automatic lowering of the window.  Longer actuations of the control switch allows for direct movement control of the window in the downward direction.  Stall current sensing and excessive time sensing provide protection to the motor and the drive circuitry.

Abstract: Method and circuitry is disclosed for controlling and stabilizing temperature of a resistance heat sealing element used in packaging operations. Temperature of the heat sealing element is measured by monitoring its resistance by means of a current sensing resistor placed in series with the heat sealing element. The resistivity of the heat sealing element is a function of temperature and current measurement, assuming substantially constant applied voltage, is an accurate measure of sealing element temperature. The circuitry reduces application of electric power to the sealing element in response to current in the sealing element dropping below a predetermined level. The circuit either continues application of electric power, or increases it, in response to the current being above the predetermined level. Circuitry is also provided for compensating for undesirable line voltage changes to maintain the heating element at a constant temperature. Means is provided for adjusting the predetermined temperature at which power cut off occurs. The circuit and sealing element can be operated in either a continuous manner of in a "one-shot" fashion which has been determined as particularly useful for making seals which bear embossed indicia.

Abstract: @ The present invention pertains, in a particularly preferred embodiment, to an apertured, macroscopically expanded, resilient three-dimensional polymeric web which is believed to have particular utility as a breatheable barrier for a disposable bandage such as a diaper. The web preferably comprises a deeply drawn three-dimensional structure containing a multiplicity of debossments of macroscopic (i.e., visibly perceivable by the normal human eye at a perpendicular distance of about one foot) cross-section, each of said debossments originating as an aperture in a first surface of the web and having a continuously interconnected side wall extending in the direction of a second, remotely located parallel surface of the web. The side wall of each debossment terminates to form an end wall in the second surface of the web. The end wall includes a multiplicity of apertures, each of said apertures being sized and shaped to independently support an aqueous fluid meniscus. The smaller apertures in each end wall are so spaced relative to all adjacent apertures in the end wall that the aqueous fluid menisci supported in the apertures do not contact one another or the side wall. In a disposable absorbent bandage context, the second surface of the web containing the end walls with small apertures therein is placed in contact with the absorbent core portion of the bandage and the surface of the web in which the debossments originate is oriented so as to contact the wearer's outer garments in use.
