Title: Method and means for dynamic correction of  electrostatic deflector for electron beam tube
Inventor: HARTE KENNETH J
IPC: H01J29/54
Filed: 1981-09-09
Granted: 1982-08-31
Abstract: ABSTRACT OF THE DISCLOSURE An electron beam tube electrostatic deflection system and method of operation is described.  The electron beam tube includes an eight-fold deflec-tor and means are provided for applying two different quadrupole correction electric potentials to selected ones of the eight-fold deflector members and for applying an octupole correction electrical potential to all eight deflec-tor members.  In the preferred embodiment, the quadrupole and octupole cor-rection potentials applied to one set of four deflector members are repre-sented by the respective values (V2c- ?), (-V2c- ?), (V2c- ?) and (-V2c- ?), and the quadrupole and octupole correction potentials applied to the second set of four deflector members are represented respectively by the values (V2s+ ?), (-V2s+ ?), (V2s+ ?) and (-V2s+ ?) where the quadrupole correction electric potential   ,               (1) the quadrupole correction electric potential    ,               (2) and the octupole correction potential ? applied to all eight of the eight-fold deflector members is given by the expression                     (3) where A2c, A2s and A4 are constants, Vx and Vy are the x and y deflection elec-tric potentials, and -Vc is the cathode voltage of the electron gun used in the electron beam tube apparatus.  In preferred arrangements, the electrostatic deflection system further includes means for applying a dynamic focusing elec-tric potential to the objective lens assembly of the electron beam tube appar-atus in conjunction with both the correction and deflection electric potentials described above.  The dynamic focusing electric potential is              (4) where ADF is a constant and VOBJ(O) is the uncorrected value of the direct current objective lens supply voltage.  Both deflection and correction electric potentials are developed by an eight-fold deflector voltage generator which includes as its heart a novel octupole-quadrupole generator.  The corrected electrostatic deflection system can be used in a simple electron beam tube structure employing only a single eight-fold deflector assembly for deflecting with low aberration a finely focused electron beam onto any desired address point on a target plane.  Alternatively, the corrected electrostatic deflec-tion system can be employed with a compound electron beam tube apparatus of the type employing a compound coarse and fine deflector system sometimes re-ferred to as a fly's-eye type electron beam tube.  In the compound electron be m tube apparatus, the eight-fold deflector assembly is employed as the coarse deflector assembly and preferably is fabricated in two eight-fold sec-tions which are electrically interconnected.

Abstract: ABSTRACT     A lifting jack for lifting loads and exerting a pulling force between two locations includes an I-beam standard having a series of uniformly shaped and evenly spaced apertures, an upper runner disposed about the standard and carrying a first climbing pin which is adapted to fit within a corresponding one of the various apertures, a lower runner disposed about the standard and carrying a second climbing pin also adapted to fit within a corresponding one of the various apertures.  The upper and lower runners are connected together by a pitman and these three components are further assembled to a lever which is pivotally attached so as to provide a jacking action to the upper and lower runners.  The lever has a pair of fulcrum points only one of which is used with any one jacking cycle, depending upon which runner is advancing and which climbing pin is to be inserted into a corresponding aperture.  The pitman is arranged into a single-piece, U-shaped lateral cross-section configuration providing greater strength and durability at a very critical point in the construction.  A reversing switch and reversing latch combination are arranged relative to the upper and lower runners so that the direction of movement of these runners may be reversed.

Abstract: ABSTRACT OF THE DISCLOSURE           A system for measuring the flow rate of electrolytic fluids includes a flow cell which has a cylindrical flow channel receptive of the fluid flow to be measured and a pair of spaced apart electrodes configured to conform to the cylindrical surface of the flow channel and to be flushed therewith.  The electrodes are electrically conductive and inert to the fluid of the flow and a channel is configured to effect contact of the electrodes with the fluid flow for a desired range of flow measurement.  A monopolar pulse train is applied across the electrodes to effect a cell impedance across the electrodes which is inversely proportional to the rate of flow.  A control signal is produced in response to the potental across the electrodes for a given unit of time and this control signal is applied to a generator for producing the monopolar pulse train in order to vary the pulse train current in the given unit of time to effect an increase in the current in response to an increase in flow rate whereby the cell impedance is stablilized for every flow rate and the . electrode potential is representative of the flow rate.     ,

Abstract: TITLE  OF THE INVENTION A Transversal Type Smear-Desmear Filter ABSTRACT OF THE DISCLOSURE A smear-desmear filter having n frequancy dependent group delay characteristic and implemented by a transversal filter.  This filter comprises a plurality of delay elements, each having the delay time 1/(2f2), where f2 is the highest frequency component of an input signal: tap weight coefficient means for obtaining the product of the output of the tap and the corresponding predetermined weight coefficient which is supplied from digital memory; and an adder for summing up a11 the output of the tap weight coefficient means.  A tap and/or a tap weight coefficient means is provided for every (m) number of delay element where (m) is an integer larger than 2, thus, the number of tap weight coefficient means merely 1/m.  The tap weight stored in the digital memory is determined by the position (n) of a tap, a delay time (?) of each delay element, the required delay expansion width (a), and the value of said integer (m)  The obtained delay characteristic is sinusoidal in the given frequency band and as a result, this invention enables the decreased use of weighted taps as compared to the conventional art.

The auger has a central body with a large diameter portion extending through the hopper, a small diameter portion disposed within the tube and a land extending along and around the body to define a generally helical flute that serves as an ingredient flow path of variable cross-sectional area.  A series of non circular openings arranged along the tube allow the ingredient to escape in a uniform manner, the effective size of the openings being variable by changing the relative rotational positions of the tube and an apertured sleeve that surrounds the tube.  The positions of the openings is also variable by rotating the tube and the sleeve together to further improve the uniformity of distribution.
