Abstract: ABSTRACT OF THE DISCLOSURE:         A process and apparatus for filling and packing a chromatographic column by the wet route in which a compression chamber is attached to one end of the column having an internal bore equal to the internal diameter of the column and aligned therewith to form a combined chamber, a fluid suspension of packing particles is introduced into the combined chamber and then a piston member is axially displaced  within  the  compression  chamber  toward  the chromatographic column to compact the packing particles in the column.  The suspension liquid flows out of the column through a conduit formed through the piston and/or through the cap at the other end of the column.  After compression, the compression chamber and piston are separated from the column and the packed column may then be attached to a chromatograph for use.  Vibrators may be provided on the column  or  compression  chamber  to  promote  transverse rearrangement of the particles during compression.  The liquid suspension of packing particles may be introduced into the combined chamber via a channel through the piston, or through the compression chamber after removing the piston,  or through the opposite end of the chromatographic column.  A porous plate may be placed over the conduit to prevent packing particles from exiting the combined chamber with the suspension liquid.

Abstract: ABSTRACT         The present invention relates to a bipolar transistor and its fabrication method.  It concerns an improvement in self-aligned planar transistors and fabrication process therefor.  The surface of a base-emitter junction is covered and protected by a direct nitrided film of silicon nitride.  The base contact electrode is made of highly doped polysilicon, the surface of which is thermally oxidized to form a silicon dioxide layer, which terminates on the surface of the silicon nitride film and separates the base contact electrode from the emitter contact electrode.  The process for fabricating the transistor by the present invention utilizes an over etching of silicon dioxide film.  The base, emitter and their contact electrodes are self-aligned by use of only one pattern lithographically fabricated on a stack of silicon nitride films and a silicon dioxide film.

Abstract: SCHEDULED HOT WATER HEATING BASED ON           AUTOMATICALLY PERIODICALLY ADJUSTED HISTORICAL DATA            Abstract of the Disclosure:    A conventional hot water heating system generally of the type for heating water in multiple units of hotels, motels and the like and using any heating medium has a processor and control assembly operationally connected to at least a heating control means, a water temperature sensing means and a water flow sensing means thereof.  The processor and control assembly divides the time into exact time periods, say one-half hour, and the time periods are grouped into a group of consecutive time periods, say a week.  Taking any individual time period, a directly preceding time period is checked with the same time period in the preceding group of time periods and if the two match within a given degree, the assembly adopts all of its settings from its particular time period a week ago.  In addition, the assembly exactly records the various settings throughout that particular time period and when that time period comes up again one week from now, those are the new settings by the processor and control assembly to be used.  Still further, at any time in a time period that high hot water flow from the water tank is detected by the water flow sensing means and the heating control means has not yet begun to begin heating more hot water, the water flow will immediately turn on the heating control means to thereby eliminate needless delays in the heating of water.  By the heating of water in the manner described, therefore, the maximum water temperature can always be maintained at a minimum and there is still relative assurance of a hot water supply at all times.

Abstract: METHOD AND APPARATUS FOR DETECTING AND COUNTERACTING A DEFORMATION OF THE STOCK DISCHARGE GAP IN A HEADBOX                  OF A PAPER MACHINE         Abstract of the Invention The invention relates to a method and an apparatus for detecting and counteracting a deformation of the stock discharge gap in a paper machine headbox, which is caused by thermal expansion due to the temperature of the stock and/or the pressure of the stock.  This is achieved by ultrasonic transducers located close to the slice opening which obtain measurement results relating to the distance between the roof member and the apron beam member of the headbox.  At least two such transducers, one preferably located close to a side wall of the discharge gap and the other preferably located midway between the side walls, give information about a possible difference between the measurement results caused by the deformation.  This dif-ference serves as a guide for adjusting the temperature of the apron beam member and/or the roof member in such a way that the deformation is reduced in magnitude or entirely eliminated.

Abstract: HIGH VELOCITY MSFB PROCESS            Abstract A high-velocity, multisolid fluidized bed pro-cess utilizes a reactor (1) having a reduced-cross-sec-tional area  (6)  in a lower region wherein large bed particles (4) are fluidized and/or entrained by high-velocity, fluidizing gas (2). If they are entrained by the gas, they are lifted to the enlarged-cross-section, upper region (7) wherein the reduced velocity fluidizing gas now either fluidizes the particles and/or allows them to drop back to the reduced-cross-section zone.  Meanwhile, the fluidizing gas entrains fine bed particles (5) at high velocity through the reactor.   The fine particles are recycled out the top of the reactor and back into the reactor in the reduced-cross-section zone.

The actuator includes a body with an interior first ball race and first and second ends; a first stop stationary with respect to the body for engaging and limiting travel of balls along the first ball race toward the first end; an output shaft rotatably supported within the body and having an exterior second ball race; a second stop stationary with respect to the shaft for engaging and limiting travel of balls along the second ball race toward the first end; and a piston reciprocally mounted within the body for application of fluid pressure to produce movement of the piston toward the first or second end.  The piston has a sleeve coaxially receiving the shaft, with a third ball race confronting and corresponding to the first ball race to form an outer set of races and a fourth ball race confronting and corresponding to the second ball race to form an inner set of races.   The third and fourth ball races extend over a sufficient axial length of the sleeve projecting beyond the first and second stops, respectively, toward the first end, as measured with the piston positioned at its end limit of travel toward the first end, to permit substantially unimpeded rolling travel of balls within the outer and inner sets of races as the piston reciprocates within the body between its end limits of travel.  The actuator further has a third and a fourth stop stationary with respect to the sleeve for engaging and collecting balls in the outer and inner sets of races for regrouping balls toward the first stop as the piston travels toward the first end.

Abstract: ABSTRACT OF THE DISCLOSURE            A control device for regulating the output voltage of a voltage regulator wherein the output from that regulator would normally be variable includes inputting that voltage to the control device.  There are two overlapping bands which define an effective bandwidth between the upper limit of the lower band and lower limit of the upper band.  The output of the device provides a signal responsively regulated in the effective bandwidth such that the output from the regulator can be similarly regulated.  In power generation systems a narrow bandwidth can be effectively maintained to permit narrow varia-tions of voltage.  A micro-processor facilitates changing the regulated levels for the control device such that the output from the control device can be selectively and controllably changed as desired.

Abstract: ABSTRACT OF THE DISCLOSURE:         A method and a device for measuring an electric quan-tity average value related to a series of trains of a periodic wave, which wave trains having a variable number of complete periods of the periodic wave and being each produced during a corresponding one of successive time intervals. The mea-suring device comprises a circuit for measuring the elec-tric quantity related to the wave train produced during each time interval considering that the wave train is ininterrupted. A storage circuit memorizes the so measured electric quantity. An impulse is produced in response to each complete period of the periodic wave in each wave train.  A first memory counts the number of impulses of the wave train of each odd time interval, multiplies the so counted impulses with the measured electric quantity related to the wave train of the odd interval to produce a multiplied value delivered on an output as the electric quantity average value during the one of the time intervals immediately following the odd interval. A second memory counts the number of complete periods in the wave train produced during each even time interval, multi-plies the so counted periods with the measured electric quantity related to the train of the same, even interval to produce a multiplied value delivered on the output as the electric quantity average value during the time interval immediately following the even one.
