Abstract: ABSTRACT OF THE DISCLOSURE A method of manufacturing packaging-container blanks is disclosed which method includes forming a substantially continuous sheet of blanks which sheet comprises a substrate and a coaling material attached to said substrate.  The coating material at the edges of the blanks of said sheet either extends beyond the substrate or is unattached to the substrate adjacent the edge, or both.  The sheet of blanks is manufactured by extruding a molten thermoplastic coating material onto the substrate between two revolving cylindrical rolls.  The substrate and the coating material are joined in such a manner that at spaced, selected intervals, elongated zones are provided where they are unattached to each other.  These unattached zones include zones extending transversely with respect to the sheet of blanks and which trans-versely extending unattached zones are produced by grooves on the periphery of at least one of the rolls which grooves are suitably arranged at intervals about the periphery of the roll to correspond to the pre-selected unattached zones desired.  The substrate is perforated transversely within the unattached zones so that it may be parted after the coating material is applied by means of a longitudinal jerk.  The coating material is cut along the zone by means of blades arranged in the grooves on the grooved roll.  Such blades arranged in the grooves may also be used to cut the sub-strate if desired rather than using the perforated-jerk arrange-ment.  Longitudinally extending unattached zones are also contemplated.  Also disclosed is an apparatus for performing the above method.

Abstract: ABSTRACT OF THE DISCLOSURE       This disclosure depicts and describes a unitized, in-line electron gun for television cathode ray tubes having a bead-type structure for mechanically supporting, spacing, aligning and electrically isolating gun components.          This disclosure is particularly directed to an improved system of electrode support that absorbs stress induced during the mounting process to leave the gun structure substantially free of residual stress, thus reducing the incidence of bead fracture and electrode displacement.          The electrodes are supported as a coherent unit in spaced tandem succession along the gun's central axis by electrode support tabs extending from each electrode with the support tabs embedded in two elongated, axially oriented structural beads positioned on opposite sides of the electrodes   The tabs on one of the electrodes comprise on each side thereof a pair of tabs spaced transversely to the gun's central axis.  The support tabs have a distal end and a stress-absorbing section, the distal end of each of the tabs being embedded in one of said structural beads, with the stress-absorbing section at most partially embedded in the structural bead.  The stress-absorbing section is of such composition, shape and dimension as to deflect beyond its elastic limit during embedment of the tab in the structural bead and to thereby yield and set permanently in a deformed but supportive attitude substantially free of any residual stress.

Abstract: Abstract A  pickup cartridge encloses a stylus arm car-rying a stylus at one end thereof.  The other end of the stying arm is secured to a connector plate via a compliant member.  A spring releasably clamps the stylus arm in a retracted position.  A pair of elastic straps extend be-tween a pair of spaced end ribs.  The rear end of the car-tridge has a pair of hooks for releasably retaining the pair of spaced end ribs.  The rear surfaces of the elastic straps are at a certain angle with respect to the front surfaces thereof.  The connector plate is secured to the slanted rear surfaces of the elastic straps to establish an angular orientation of the connector plate relative to the cartridge so that, when the stylus arm is held in the retracted position in the cartridge, the compliant member is unstressed.  The connector plate is adapted to be rotated upon reception of the cartridge in a player to permit the stylus arm to protrude outside the confines of the cartridge without stressing the compliant member.          The clamping spring is locatable in one of three positions relative to the cartridge.  In the top position, the clamping spring retains the stylus arm in the retracted position against a stop in the cartridge.  The middle position of the clamping spring permits the stylus arm to protrude outside the confines of the cartridge.  The bot-tom position is for manufacturing purposes.  Means are provided for accurately positioning the cartridge in a compartment provided in the player.

Abstract: ABSTRACT OF THE DISCLOSURE           An equalizer has N resistor-reactor stages each pro-ducing one of N bumps, each bump adjustable in amplitude, and also in center frequency (the frequency at which the extreme-amplitude point of the bump lies).  Each bump's center frequency is shiftable within a respective one of N successive limited fre-quency ranges, each defined by a minimum and maximum end frequency with a middle frequency midway therebetween. With any two adjoin-ing bumps adjusted such that their center frequencies lie at their middle frequencies, the center frequency of one bump can be shifted towards the middle frequency of the other by a distance at least equal to one half the distance from the middle frequency of the one bump to the middle frequency of the other.  With any two ad-joining bumps set to equal amplitude, no matter what value, their adjoining flanks overlap and intersect at a point at least  0.6 of the way up their equal amplitudes.  The N middle frequencies (which are fixed), contrasted to the N center frequencies (which are adjustable), are substantially equidistantly spaced along an unprecedented normalized-frequency axis the constituent sections of which have been expanded and compressed in correspondence to a new mathematical function, the density-of-detail distribution function, d*, wherein  , k being a simple proportionality constant, and q being normalized frequency (f/fmax).

Abstract: THREE SPEED DECK WINCH            Abstract of the Disclosure A deck winch provides three separate speed ratios for its drum when its main shaft is turned.          With an external control lever in a neutral position a high speed ratio is attained by rotation of the main shaft in a first direction, resulting in a low drum speed.   A medium speed ratio is attained by rotation of the main shaft in a second, opposite direction.          With the control lever in its active or low gear ratio position, rotation of the main shaft in the first direction moves the drum at its highest speed relative to the main shaft.   When the control lever is in this active position and the main shaft is rotated in the second direction, the control lever is automatically shifted to its neutral position and the medium speed ratio is established.   The control lever is connected internally to engage and disengage an idler gear that mechanically interconnects the main shaft with one or several driving gears for the drum.   At any time the position of the control lever and the direction of main shaft rotation may be selected to provide any of the three speed ratios.

Abstract: CAPACITOR STORAGE MEMORY    ABSTRACT OF THE DISCLOSURE:    A semiconductor memory produced in a unipolar technology includes a cell which has an inversion capacitor with one terminal connected to a bit/sense line, the other terminal is coupled to a source of charges by a pulse from a word line.  To provide a word organized array of these cells, each word includes a source of charges produced at the surface of a semiconductor substrate and plurality of inversion capacitors are formed also at the surface of the semiconductor in spaced apart relationship from the charge source.  Information is written into the capacitors by applying voltages of two different magnitudes, representing 1 and 0 bits of infor-mation, to one terminal of the capacitors while a word pulse produces in-version layers at the surface of the substrate between the capacitors to interconnect serially the charge source with each of the capacitors.  The capacitors having the larger voltage store the greater amount of charge.  This charge can then be detected by measuring the voltage across the storage capacitors when a word pulse again connects the charge source with each of the capacitors.

Abstract: ABSTRACT OF THE DISCLOSURE         An elevator-conveyor for conveying bulk material over a predetermined path, at least a portion of which path is in a vertical or near vertical direction.  The conveyor comprises a pair of juxtaposed belts between which the bulk material is to be located and air pressure means adapted to act directly on one or both of the outer belt surfaces when the belts are in the vertical or near vertical direction so that the belts are pressed towards one another and against the interposed bulk material so as to enclose the same and so that the juxtaposed longitudinal edge portions of the belts are pressed against each other.  The improvement resides in that a terminal portion of the elevator-conveyor is designed to be located in the vertical or near vertical direction and comprises oppositely facing sub-stantially straight terminal portions of the belts disposed at an acute angle with respect to each other and defining there-between a substantially wedge shaped feed zone.  The angle is not greater than that which allows entrainment of the material therein.  The zone opens outwardly from a position where they are substantially in contact towards a feed end of the conveyor.          The straight terminal portions have lengths substantially greater than the maximum thickness of the feed zone.  A feed mechanism is also provided for gathering and projecting the bulk material into the feed zone.
