Abstract: ELEVATOR FOR DRILL PRESS TABLE     ABSTRACT OF THE INVENTION     An elevator for a drill press table comprises a sprocket chain suspended at the top of the drill press column to extend verti-cally downwardly along the column, and a companion sprocket wheel mounted on the drill press table for rotation about a substan-tially horizontal axis.  A friction brake mechanism restrains angular movement of the sprocket wheel and holds the table in the vertical position thereby determined.  A crank directly connected to the sprocket wheel rotates the sprocket wheel up or down the chain correspondingly to position the drill press table.  In the preferred arrangement, a ratchet mechanism allows the crank to override the brake in the up direction of the sprocket.  Rapid and reliable adjustment of table height is achieved.

Abstract: Abstract During the startup and/or shutdown cycle of an ink jet printer, a movable probe in the form of a thin hollow tube, is inserted into the flight path of the ink droplets.  The tube is normally positioned relative to the droplets flight path.  At the shutdown cycle, the charge electrode is removed from the vicinity of the jet streams.  The undeflected droplets are caught by the hollow tube.  The tube is then moved to a position next to the nozzle plate.  The ink jet printer head may then be turned off and all ink is caught in the tube.  At startup the sequence is reversed until the tube is back at its normal position.

Abstract: ADJUSTABLE BOXCAR DOOR WITH DOUBLE ROLLER    BOGEY TRAVERSE MECHANISM AND METHODS FOR FABRICATING AND INSTALLING SAME          Abstract An adjustable rolling type boxcar door has a main panel and a telescoping adjustable panel at its bottom for adjusting the overall height of the door to fit a variety of door openings.  The adjustable panel is slidably retained between side frames in the main panel by stop blocks mounted along the inside edges of the side frames.  The width of the door may be also ad-justed by positioning a spark strip either closer or further away from the inside edge of the door opposite the closure mechanism.  A pair of double roller, pivot-ally mounted bogeys are mounted in the adjustable panel and support the door from a door track mounted to the side of a boxcar.  The double roller bogeys provide an improved traverse mechanism for supporting the consider-able weight of a boxcar door and carrying it across what may be an uneven and rough track.  There is also dis-closed a method for adjusting the height of the door and installing it to a boxcar including the steps of measur-ing the height of the door openings, adjusting the height of the door by fixing the position of the adjustable panel, lifting the door, inserting the top of the door into the top door retainer, and positioning the lower end of the door on the door track and securing it into place by welding J-straps to the lower end of the door.

Abstract: Abstract of the Disclosure Disclosed is a method of preparing a cathode-diaphragm assembly for an electrolytic cell, where the diaphragm is adherent, e.g., to itself and to the cathode.  The cathode-diaphragm unit is prepared by first depos-iting a protective film on the catalytic cathode, and thereafter depositing the diaphragm material under such conditions that the diaphragm material becomes self-adhering and conforms to the cathode but is spaced from the cathode.  In this way the diaphragm is subsequently removable without damage to the cathode catalyst.

Abstract: ORANGE JUICE CONCENTRATE                   Rudolf G. K. Strobel Abstract of the Invention A natural orange juice concentrate prepared from natural orange compounds is disclosed.  The orange juice concentrate has at least 35% solids including pulp, non-volatile compounds, pectin and volatile compounds.  This orange juice concentrate has at least 65% of the aroma and flavor volatile compounds of the natural juice.  The aroma and flavor volatile compounds comprise a low boiling fraction and a higher boiling fraction in a ratio of at least 4:1.  The ethyl butyrate level is at least .1% of the total volatile compounds, the proportion of ethyl butyrate to limonene being in the range of .0015:1 to about 0.6:1.   The orange juice concentrate is prepared by separating natural orange juice into a pulp portion and a serum portion.  The serum portion which comprises 7% to 20% solids and from 80% to 93% water is concentrated by removing essentially pure water.  The concentration step can be accomplished by freeze concentration or by sublimation concentration.  When sublimation concentration is used, the pulp does not have to be separated from the serum.          Substantially 100% of the non-volatile solids are retained.          Moreover, the product is substantially free of oxidative degradation products.

Abstract: Abstract of the Disclosure An improved wire or fiber strand payoff neutralizer adapted for multi-position application is described, which permits numerous individual strands of wire or fiber that will be formed into a cable to be payed out linearly and uniformly under controlled and regulated tension to the other components of a cabling machine.  The present invention utilizes a split shaft, the reel containing the wire or fiber strand being mounted on an arbor portion of the split shaft, and a flyer being mounted on the driven portion of the rotor shaft.  The wire or fiber strands then travel from the product supply reel to the flyer and then back to the hollow core of the rotor shaft and thence to the other components of the cabling system. The flyer and the rotor shaft rotate at the same speed as the other compo-nents of the cabling system, as well as in the same direction.  A direct current-operated stepper motor drive is directly coupled to an encoder, which receives signals from a secondary linear encoder that is in contact with the payed out wire or fiber strand.  The direct current stepper motor drive thus controls the fiber or wire payoff from the product reels in order to provide a predetermined tension and twist to the cable assembly.

Abstract: ROTARY DRUM FILTER AND METHOD OF OPERATION FOR MEDIUM CLEANING     ABSTRACT OF THE DISCLOSURE         A rotary vacuum filter wherein each filtration sector of the filter is backwashed with filtrate and/or separately supplied gas or wash liquid while the sector is submerged in the feed slurry in the tank.  As each sector starts to resub-merge in the tank, vacuum is applied so that the sector and associated hydraulic system is quickly and completely filled ith filtrate and a thin cake or film of solids forms on the filter medium whereupon with the sector still submerged, vacuum is cut off and a positive pressure is applied by either or both pressured gas or liquid supplied through the valve thus forcing filtrate back through the cloth to effect washing thereof.  After the wash, vacuum is reapplied for cake for-mation.  The drum includes an internal manifold under each filtration sector.  The manifolds are mounted on the interior wall of the drum and are secured directly to the drum wall as structural members.  Additionally, each manifold serves as a reservoir for storage of wash liquor.

Abstract: ABSTRACT OF THE DISCLOSURE           Character matrices are stored in and retrieved from a magazine automatically.  The matrices can be complete discs or pie-shaped "petals" which are assembled to form a disc.  A single pivotably-mounted support arm is used to support the spinning disc, and to move it for selection of concentric arrays on the disc, as well as for storage and retrieval of matrices. A reversed zoom lens is used to magnify the characters.         The character spacing carriage can move continuously in order to increase the speed of operation.  Proper location of the characters can be done by simply altering the carriage speed between projections, or by using a shuttling lens for character spacing compensation, together with flash delay and carriage deceleration.          A system for inputting images from any one of three separate discs also is provided.          A double-dove prism and optical wedges are used for altering the shapes of characters.          Rules are formed by operating a flash-lamp very rapidly to shine light through an appropriately-shaped opening and moving the image along the photosensitive surface in a linear path.  The matrix can be moved in a varying speed mode in which the matrix is moving slowly or stationary when the character is flashed  This allows the light intensity of the flash lamp to be raised significantly without significant degradation of the quality of the output.          Controls are provided for automatically adjusting the base-line of the characters, the margins, the degree of enlarge-ment, the flash intensity, and the focus.          A simple attachment is provided for doubling or halving the size of the characters.     The machine can produce output on photographic film or paper or electrophotographic material.          Means are provided for automatically inserting graphic matter (pictures) into text matter for composing full pages, and for making half-tones.

Abstract: ABSTRACT  THE DISCLOSURE    An automatic electronic cab signal test set for testing the integrity of a pair of pickup coils and for checking the sensitivity of the amplifier of the cab signal receiver.  A mode selector is connected to a clock oscillator which pro-duces clock pulses.  The clock pulses are connected to an up/down binary counter which sequentially counts up from zero to a maximum count and then sequentially counts down from the maximum count to zero.  The up/down binary counter is connect-ed to a code selector which changes the time constant of an R-C network of a code oscillator.  The code oscillator illuminates an indication when the cab signal receiver is under test and modulates the carrier signal of a carrier oscillator.  The modulated carrier signal is fed to the input of a constant current source which has its output directly connected to the pickup coils and the amplifier of the cab signal receiver.  A low-high switch conditions and powers the test set which goes through a simulated low rail current speed command sequence and then goes through a simulated high rail current speed command sequence.
