Abstract: An elongated metal workpiece such as a slab or billet is moved longitudinally beneath a grinding head by a reciprocating carriage mounted on an elongated track. The carriage receives a billet from a charging table, reciprocates the billet beneath the grinding head for a plurality of grinding passes, and then delivers the finished billet to a discharge table. The grinder head includes a rotating grinding wheel mounted at the end of a first arm which is pivotally secured to one end of a pivotally mounted second arm. The vertical position of the grinding wheel, and hence the downward force exerted by the grinding wheel on the billet, is principally determined by the angular position and torque, respectively, of the first arm while the horizontal position of the grinding wheel transverse to the longitudinal axis of the billet is principally determined by the angular position of the second arm.

Abstract: A breaker reinforcing tape for belted pneumatic tires, a method of making such tape, and a method of constructing such tires therewith, are disclosed. The tape includes a generally sinusoidally crimped strip of uncured rubber and a plurality of similarly crimped parallel cords having their undulations following and nesting in the undulations of the crimped strip, the cords at successive apexes being secured to successive apexes of the strip. A second uncured rubber strip in a flat condition is secured to alternate ones of the apexes of the undulations of the array of cords and the crimped strip at one face of the latter. At least one frangible element is interposed in a fixed and substantially flat condition between the crimped and flat strips for releasably reinforcing and stabilizing the flat strip against inadvertent expansion that would prematurely reduce the amplitude and frequency of the undulations of the crimped strip and its associated cords.

Abstract: A system for indicating the sweep rate of an oscilloscope time base. A counter is enabled by a sweep gate signal to permit clock pulses having a predetermined repetition rate to be counted during the time a sweep-driving ramp waveform is generated. The count output, which is proportional to the length of a time-base sweep, is decoded to generate specific control signals indicative of the sweep rate thereof. The control signals may then be used by a utilization means to provide a visual readout of the time-base sweep rate or to provide auto ranging for a digital voltmeter scaled in time units for time interval measurements.

Abstract: Improved method of making an abrasive wire for sawing stone. The improvement resides in the step of affixing the solid abrasive body to the support element. This step is accomplished by deforming the axially protruding free end of the underlying smaller diameter portion of the support element so that it enlarges and assumes the same diameter as the larger diameter other end of the support element, thereby sandwiching and locking the abrasive body solidly therebetween.

Abstract: A catalytic process is provided for the selective production of para-xylene by disproportionation of toluene in the presence of a catalyst comprising a crystalline aluminosilicate zeolite having a silica to alumina ratio of at least about 12 and a constraint index within the approximate range of 1 to 12, which catalyst has undergone controlled precoking, i.e. selectivation, by exposing the same to a thermally decomposable organic compound at a temperature in excess of the decomposition temperature of said compound, generally greater than 1000.degree. F., but less than about 1200.degree. F., at a hydrogen to organic compound mole ratio between 0 and 1 to deposit at least about 2 weight percent coke thereon and thereafter contacting toluene with the resulting coke-containing catalyst under disproportionation conditions including a temperature between about 800.degree. F. and 1025.degree. F., and preferably between about 825.degree. F. and 1000.degree. F.

Abstract: A valve construction, particularly a three-way, two-position valve which may be used by itself to control fluid flow, or which may be used as a pilot valve to control operation of a larger valve. The valve comprises a cartridge which may be installed within or removed from the bore of a valve body as a unit. The cartridge unit comprises a valve plunger, a plurality of similar glands, and a plurality of similar separators carried by the plunger, with static seals on the glands and dynamic seals between separators, and a spring for urging the plunger to a predetermined position.The cartridge unit is held within a body bore by means of a cartridge nut which is threaded into one end of the bore. The nut has one end bearing against a separator at one end of the cartridge unit and presses a separator at the other end of the unit against a fixed abutment in the bore, so that axial movement of the plunger does not cause separation of the glands and separators.

Abstract: An attachment for use with an overhead door having limited head room. The door is made of hingedly connected sections and movable between a closed and an open position on a track. The attachment comprises a first member adapted to be attached to the top section of the door. A second member is pivotally connected to the first member. Track engagement means are attached to the second member and abutment means are positioned on the second member to abut a stop positioned on the exterior of the track when the door is in the closed position. Abutment of the abutment means on the stop acts to stop movement of the second member in the track at a point just prior to the door reaching the closed position.

Abstract: A hand-held label marking device prints selected bar code character information on labels by scribing selected code bars upon one area of a moving label juxtaposed with a printing medium and prints corresponding alpha-numeric character information upon another area of the label by impacting the label and printing medium against selected print elements, thereby establishing a standard symbol, such as that currently prescribed in the United States by the Universal Product Code. Further alpha-numeric information is printed upon a further area of the label by a reciprocating printing mechanism in the same device to provide consumer-readable price information. A compact arrangement of component parts enables the printing of a full range of bar code character information in accordance with a compact symbol standard such as the zero-suppression symbol standard of the Universal Product Code, together with the corresponding alpha-numeric character information.

Abstract: A continuous method for regenerating deactivated catalyst particles in a regeneration zone through which the particles are downwardly movable by way of gravity-flow. Particles are initially introduced into an upper carbon-burning/halogenation zone wherein they are contacted, in a first section, with a first air stream and a first mixture of steam and a halogen, or halogen-containing compound. Partially regenerated/reconditioned particles are then contacted, in a lower second section, with a second air stream and second mixture of steam and halogen. From this two-sectioned, carbon-burning/halogenation zone, the catalyst particles flow via gravity into a drying zone wherein they are contacted by a substantially dry air stream.

Abstract: An electronically controlled embossing machine for embossing alpha-numeric characters on flexible sheets such as, for example, plastic or metal credit cards or nameplates. Embossing is accomplished by two constantly rotating embossing wheels which carry radially movable embossing molds about their peripheries. One embossing wheel carries male or projecting embossing molds; the second wheel carries matching female or intaglio embossing molds. Selection of a certain character via a keyboard, or by electrical signals from any data source, causes the appropriate male and female molds to be moved radially outwardly on each wheel by mechanical mold cam levers. A flexible sheet, such as a plastic credit card blank, interposed in the bite of the two embossing wheels, is embossed by the radially extended embossing molds in a rolling-squeezing process.

Abstract: Thermally actuated pressure relief is provided for lightweight filament or fiber wound pressure vessels. A pressure release device is provided for a filament or fiber wound pressure vessel which device contains an alloy insert which will soften and release the pressure in the vessel upon the device being subjected to a predetermined temperature range. The temperature range must be below the degradation temperatures of the pressure vessel and above the normal ambient use and storage temperatures of the vessel. The alloy in the pressure release device must be capable of taking the shear stress of the cyclical pressurization and depressurization of the vessel without failure, which shear stress would be both the mechanical shear between the alloy and the walls of the hole in the device, i.e.

Abstract: A transceiver (transmitter-receiver) for high frequency data pulse signals is connected to a coaxial cable transmission line through a distributed delay line which has an impedance equal in value to the characteristic impedance of the coaxial cable transmission line. The transceiver transmitting and receiving circuits are tapped into the transmission line and form a part of the distributed delay line. When not in the transmitting mode, the transmitter circuit appears as a reactive element of the distributed delay line and thereby introduces minimum loss or reflection into the transmission line. The transmission line can serve as a trunk line for a number of transceivers by permitting virtually unrestricted multipoint connections to the line.
