Title: Pulverizing apparatus
Inventor: IHARA YOSHITAKA
IPC: B02C17/16
Filed: 1989-07-04
Granted: 1992-11-03
Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to an apparatus for pulverizing quick lime into a slurry form.  It has a vertical shell and a rotary shaft mounted in the shell.  An agitating layer and a pulverizing layer are formed in the shell at its upper and lower portions, respectively.  The material fed from top of the shell is agitated and melted into smaller particles in the agitating layer and then pulverized into fine particles in the pulverizing layer.  The fine particles are discharged from top or middle of the shell.  A discharge pipe is provided so as to extend upwardly from the discharge port at middle of the shell.  An agitator may be provided in the discharge pipe.  The material to be pulverized is prevented from going from the inlet directly to the outlet without passing through the pulverizing layer.

Abstract: In a hydrostatic transmission, an oil expansion reservoir is formed as an integral part of the hydrostatic transmission housing, providing an extension to the housing chamber which encloses motion transmitting components of the transmission. The reservoir is defined by a yieldably compressible hollow body mounted within the chamber of the transmission housing. The hollow body is sealably attached at its open end to the outer wall of the transmission housing. The body includes a continuous cylindrical sidewall connected to a closed end wall and formed of alternating reversed annular folds which cause compression and expansion of the body sidewall to occur in a bellows-like fashion rectilinearly along a central longitudinal axis of the body.

Abstract: For the measurement of large currents, d.c. as well as a.c., a so called zero-flux current transformer may be used. It comprises two identically wound toroidal cores (11,12), in which the magnetic flux induced by a main or primary current (I1) is neutralized by a counter-flux induced by a compensation current (I2), which by means of an amplifier circuit (40) is passed through a compensation winding (14) common for both cores (11,12) and having many turns. The compensation current (I2) is adjusted by means of the amplifier (40) to such a value, that the mean flux in the cores (11,12) is zero. The intensity of the compensation current (I2) is measured by the voltage drop across a measuring resistor (15). Any unbalances between the primary and secondary ampere-turns are sensed by a detecting circuit comprising a sensing winding (21,22) wound on each core (11,12) and divided into two subwindings which carries a magnetizing current (I3) from a current source (23) in such a way, that the odd-harmonic components contained in the magnetizing current are outbalanced, whilst the even-harmonic components contained therein are added and conducted to a synchronous rectifier (32) to provide a control signal to the amplifier (40) for the adjusting of the compensation current (I2). 
<??>Hereby is obtained a largely improved signal-to-noise ratio for the signal applied to the synchronous rectifier (32), and the need for a complex and expensive active 2nd-harmonic filter is eliminated.

Abstract: A porcess for producing a foamed synthetic resin body comprising continuously extruding a foamable thermoplastic resin extrudate composition from an extruder die (2, 3) into a reduced pressure zone (11, 19), subjecting the extrudate (F) to en expansion molding step, a cooling-hardening step and a cutting step while transporting the extrudate through the reduced pressure zone to obtain a foamed piece of predetermined length (F min ), shutting off a portion (19) of the reduced pressure zone surrounding the foamed piece from the other portion thereof when the foamed piece has reached a specified position to restore the foamed piece surrounding portion to a normal pressure, subsequently discharging the foamed piece into the atmosphere, and thereafter bringing the surrounding portion into communication with the reduced pressure zone again upon reducing the pressure. Foamed resin bodies of desired expansion ratio and shape can be prepared continuously with high cooling efficiency. An apparatus for practicing the process is also disclosed. Such apparatus includes means to form a continuous length of extrudate with a vacuum chamber and means to cut the extrudate to length and means to pass (10, 10 min ) the cut extrudate into a second chamber (19), and then to cause the cut length to exit the second chamber (11) without affecting the reduced pressure in the chamber or reduced pressure zone.
