Abstract: ABSTRACT        Apparatus for the irregular treatment of one or more yarns includes a treatment station through which the yarn is moved continuously in a relatively fixed axial direction.          Fluid supply nozzles are mounted in the treatment station for movement in parallel planes extending substantially perpendicu-lar to the yarn passing therethrough and are reciprocated transversely of the axial direction of movement of the yarn through the treatment station,  The speed of axial movement of the yarn through the treatment station and/or the speed of reciprocation of the nozzles is varied while the yarn is moving through the treatment station during the treatment, and a control device is provided for shifting the phase of recipro-cation of the nozzles with respect to each other and for vary-ing the relative phase shift therebetween during the treatment of the yarn so as to effect irregular treatment of the yarn.

Abstract: LOW-COST POWER-REDUCING   DEVICE FOR HID LAMP     ABSTRACT OF THE DISCLOSURE         Add-on device for high-intensity-discharge lamp and ballast which reduces the wattage at which the lamp is operated.  The add-on device has two parallel circuit paths, one of which is an RC circuit and the other of which com-prises a triac.  A diac connects the gate of the triac to the midpoint of the RC circuit to control the time in each half-cycle of energizing potential that the triac fires.          The predetermined relative values of the RC components and the rating of the diac control the time of firing of the triac in each half-cycle, and thus determine the wattage at which the lamp is operated.

Abstract: TITLE OF THE INVENTION  INDUSTRIAL TECHNIQUE     ABSTRACT OF THE DISCLOSURE           A system for controlling machine tool operation is dis-closed.  This system accepts an instruction directly in the form of a Boolean algebra expression.  The expression is converted to an output signal through the temporary retention of a cumulative provisional result that reflects the progressive status of a term-by-successive term evaluation of the instruction.  This technique is achieved, for example, through a "last-in, first out" memory store.  A final "truth value", i.e., the value in the cumulative sequence that immediately precedes an equality sign or other equivalent algebraic operator, reflects the actual status of some feature of the machine tool.  The next step in the operation of the tool is then taken in response to the contrast between the truth value and the specific machine response options character-ized by the expression on the opposite side of the equality sign.

Abstract: TOTAL IMAGE TRANSFER PROCESS               ABSTRACT OF THE DISCLOSURE Process for transferring overlayed multiple ink patterns from the surface of a release blanket to a receiving surface on a container or other formed article being printed.  A substantially transparent film is first formed on the release blanket, with each ink pattern being printed sequentially over this release film.  Proper printing on the release film without picking the release film or previously applied ink films is obtained when certain adhesive and cohesive relation-ships are maintained between the ink films and the release film.  An adhesive film may be formed on the article to be printed, or it may be formed over the ink  films and the release film on the release blanket. The receiving surface on the article to be printed is brought into contact with the films on the release blanket, with a resulting total transfer of the films on the blanket to the surface of the article.

Abstract: ARTICLES WITH INTERNAL CONDUCTORS AND                METHOD OF MAKING SUCH ARTICLES          Abstract of the Disclosure In a process for providing electrodes or conductors in sintered ceramic body sheets of a finely divided insulating or dielectric ceramic composition are bonded with a heat-fugitive bond.  The composition forms a dense layer when fired to sintering temperature.  A deposit of a second composition is introduced between the sheets.  This second composition has a heat-fugitive bond and develops an open structure when fired.          A plurality of these sheets and intervening deposits are consolidated whereby to obtain a heat-fugitive bonded, self-sustaining body.  This body is then heated to eliminate the heat-fugitive bonds.  The body is then heated to sintering temperature to produce a sintered monolithic body having areas of dense ceramic material and open-structured areas with each such open-structured area extending to an edge region of the monolithic body.  A conductive material is then provided in the open-structured areas by injecting molten metal into such areas, the edge regions of the sintered, monolithic body being provided with penetrable barriers and the molten metal being forced through these barriers into the open-structured areas.

Abstract: ABSTRACT OF THE DISCLOSURE      A sensor mounted on each axle of a railroad car gen-erates digital signals related to axle rotation.  The digital outputs from the sensors are fed to counters which drive a detector which compares the speeds of the axles.  When wheel slip indicated by a pulse count  difference between axles is encountered, the detector provides an output which may, for example operate solenoid-operated dump valves to increase brake pressure on both axles of the slipping axle truck.          When axle speed recovers to a non-slipping condition, the dump valves are reset and brake pressure is reduced.  The detector circuitry is also able to detect wheel slide thus permitting corrective action.  In addition to the above, the system includes provision co prevent synchronous sliding of all axles by sensing the rate of change of count.

Abstract: DUAL PACKER WHEEL UNIT FOR TILLAGE APPARATUS                 Abstract of the Disclosure A dual packer unit is disclosed that is particularly useful for sod seeding purposes.  The apparatus includes an H-shaped mounting bracket consisting of an arcuate leg connected at oppo-site ends to a pivot arm and a wheel mounting arm.  The pivot arm is integrally formed with one end of the arcuate leg at the central portion of the pivot arm, and the wheel mounting arm is integrally formed with the other end of the arcuate leg at the central portion of the wheel mounting arm so that the ends of the pivot arm may be pivotally mounted between a pair of seed tubes, and packer wheels may be mounted for free rotation at the ends of the wheel mounting arms.  When so mounted, each packer wheel is received in a furrow immediately following and in line with the seed tube.  The packer wheels are gravity biased downwardly toward a cut furrow, and the unit therefore provides sufficient flexibility to follow the contour of the ground and to follow the cut furrow regardless of the depth selected.

Abstract: ABSTRACT             An interferometer, that simultaneously employs two phase-quadrature reference beams of coherent light which interfere with a signal beam of coherent light reflected from a spot of a displaceable signal mirror insonified by an ultrasonic wave, permits an output signal to be derived which is proportional to the sum of the squares of the ultrasonic frequency component of the inter-ference between the signal beam and each respective one of the reference beams.  This output signal is inherently substantially proportional to the intensity of the ultrasonic wave then insonifying the spot of the signal mirror and independent of random phase drift and environmental vibrations in the interferometer.  This interferometric technique permits the ultrasonic wave to be in the form of pulse bursts of only a few cycles so that the output signal can be range-gated.  It is suitable for use in an ultrasonic-wave measurement and image display system.

This process yields essentially p-nitrotoluene, in addition to a smaller quantity of o-nitrotoluene and a very small amount of m-isomer.          The technology of the process is simple and provides good yields. The nitrotoluenes - especially the p-nitrotoluene - re-present interesting intermediates, for example for the manu-facture of dyestuffs.
