Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure describes a process for the manufac-ture of water gel explosives with improved performance charac-teristics, which explosives contain combustible materials, oxidizing agents, a gelling agent, water, sensitizers, and expanded thermoplastic microspheres as gas carriers.  The manufacture is carried out in various successive steps.  In a first step, the microspheres are expanded in a concentrated solution or eutectic melt consisting of part of the components of the explosive, the solution or melt having an oxygen balance which does not make the solution or. melt a safety risk at the temperature required for the expansion of the micro-spheres.  Then, in one or more steps at a lower temperature acceptable from a safety point of view the remaining components of the explosives, including the sensitizers, are admixed.  This process has the advantage of satisfying rigorous demands for safety.

Abstract: ABSTRACT OF THE DISCLOSURE           Log processing apparatus comprises a cutting machine that defines a substantially vertical cutting plane, feed mechanism that feeds a log through the cutting machine in substantially lengthwise horizontal motion parallel to the cutting plane, a measuring station spaced to one side of the cutting plane, and transfer mechanism by which a log is carried laterally from the measuring station to the feed mechanism.  At the measuring station the log is established in an optimum rotational orient-ation which is thereafter maintained through a first transfer of support of the log, to a set of jaws on the transfer mech-anism, and a second transfer of such support, to a set of jaws on the feed mechanism.  Before the transfer mechanism begins to move the log, a relationship is ascertained between a calculated plane that extends lengthwise in the log and a reference plane defined at the measuring station that has a fixed relationship to the cutting plane.  During transfer from one set of jaws to the other the log undergoes no motion.  However, one of the sets of jaws is controlledly shifted laterally to establish the log on the feed mechanism with said calculated plane in a desired rela-tionship to the cutting plane.

Abstract: ABSTRACT OF THE DISCLOSURE           Measuring devices each deliver a measuring value for a property of the measuring liquid.  From certain measuring values there are formed auxiliary values.  Each auxiliary value is compared with a threshold value in order to produce a recognition signal.  The Individual recognition signals are grouped together into a recognition-data word.          Each preparatory state corresponds to a respective pre-paratory-data word.  The calibrated state corresponds to a calibaration-data word.  The recognition-data word is com-pared with the other data words.  Upon coincidence thereof, there is produced an appropriate control signal which is delivered to a computer, in order to trigger thereat a computation operation corresponding to the preparatory state or a calibration.           For instance, in a diluted blood sample there are measured the erythrocyte concentration, the hemoglobin con-tent and the conductivity and used as auxiliary values.     Depending upon the results of the comparison of such auxiliary values with the related threshold values there is produced a control signal which triggers the correspond-ing computation of the erythrocyte concentration or the hemoglobin content in the blood sample or the calibration of such computation.     The invention is preferably employed for hemoto-logical analysis and more generally for the series analysis of liquids.

Abstract: LUGGAGE ROLLER                     ABSTRACT OF THE DISCLOSURE        A luggage roller featuring a diabolo-shaped wheel, which is preferably detachable from the piece of luggage, i.e. a con-tainer, to which it is mounted.  The diabolo-shaped wheel is more stable than prior art configurations, because of its greater ef-fective width leading to greater bearing area.  The detachable feature of the wheel leads to changeability of the luggage roller wheel when wear occurs, so that the piece of luggage does not have to be discarded when the installed wheel wears down.  This detach-able feature is typically attained by providing an axle on which the wheel is mounted which is detachable from the container.  The axle is generally of one of several alternative configurations in which a threaded connection is provided between portions of the axle assemblage, so that one portion or part of the axle assemblage may be unscrewed from the other portion or part.

Abstract: ABSTRACT           A multirow bearing for supporting a work or back-up roll of a rolling mill includes inner and outer races and tapered rollers arranged in two end rows and two inter-mediate rows between corresponding raceways on the inner and outer races.  The inner race is a unitary structure, while the outer race is comprised of two double cups.  The tapered rollers of the intermediate rows have their large ends presented toward each other and those ends bear against a center thrust rib that may be free to float in the axial direction so as to equalize radial loads between the rollers of the two intermediate rows.  The radial clearance between these rollers and their respective raceways can be less than the clearance between the rollers of the end rows and their respective raceways so that the rollers of the inter-mediate rows carry most of the radial loading.  Also, the rollers of the end rows can be at a steeper angle than the rollers of the intermediate rows, and are therefore better able to accommodate thrust loads and moments.  The large ends of the rollers in the end rows bear against rib rings that are secured to the double cups of the outer race by seal cases which serve to unitize the bearing for handling purposes.  Seal elements are bonded to the seal cases and they bear against the inner race to close the ends of the bearing.

Abstract: Docket M-295 PRINTING APPARATUS            Abstract of the Disclosure There is disclosed printing apparatus having a pivotally mounted print head which cooperates with a platen, a cam shaft to which a cam is secured for actuating the print head and to which another cam is secured for driving an  operating lever.    The operating lever is coupled to a slide which drives a feed finger and cam means for actuating an inker.  The travel of the feed finger is selectively variable by changing the position of the pivot on which the lever is mounted.  The cam means is part of a lost-motion connection which couples the slide to the inker.  As the operating lever is cammed in one direction to move the feed finger forward,  the inker is moved into and out of inking cooperation with the print head assembly.  Because of the lost-motion connection adjustment of the pivot does not affect the length of travel of the inker.  When the inker is in inking position the inker is supported at both sides of the platen thereby leaving the platen accessible during threading of the apparatus with the web of record members.  The print head assembly includes a pair of print heads, each print head having at least one series of rotatably mounted drive wheels and a support.  A plurality of printing bands having different printing elements are trained  about the support and respective drive wheels.  Each support of each print head is adjustable by exerting forces at opposite ends of the support so that all the printing elements at the support are disposed in a common plane parallel to the platen.  The Docket M-295 print heads are rigidly interconnected by plates.  Set screws threadably received by one of the plates are accessible from about the print head and act on adjusting plates which exert forces at opposite ends of the respective supports.

Abstract: ABSTRACT OF THE DISCLOSURE   Disclosed is a base band processing phase synchronizing circuit for multi-level, multi-phase superposition-modulated signal transmission systems, which requires neither an analog switch nor an analog delay line. The circuit comprises a voltage-controlled oscillator (VCO) responsive to a control signal for varying its oscillation frequency, a phase detector for phase-detect-ing a multi-level, multi-phase superposition-modulated carrier wave with reference to the phase of the output of the VCO, and a demodulator for demodu-lating the  output of the phase detector to provide a demodulated signal. -Circuitry responsive to the demodulated signal determines the phase position of the modulated carrier wave with respect to the output phase of the VCO.  A plurality of phase shifters are provided for phase-shifting the output of the phase detector by prescribed values and a plurality of discriminators discrimi-nate the outputs of the plurality of phase shifters with reference to a pre-scribed threshold level.  A plurality of first frequency-multipliers are provided for frequency-multiplying each pair of mutually orthogonal outputs among the outputs of the plurality of discriminators means.  Second frequency-multipliers are provided for frequency-multiplying each pair of mutually ortho-gonal outputs among the outputs of the demodulators.  First gate circuitry is provided which is responsive to the-output of the circuitry responsive to the demodulated signal for selectively passing therethrough the output, among the outputs of the plurality of first frequency-multipliers.  Third frequency-multipliers are provided for frequency-multiplying the pair of the output of the first gate circuitry and that of the second frequency-multiplier and a device for supplying the VCO with the  output of the third frequency-multiplier as the control signal.

Abstract: CONVOLUTED CODE MATCHED FILTER ABSTRACT OF THE DISCLOSURE           A structure and a method for detecting a binary convoluted coded signal having a plurality of code levels ranging from a low level, high repetition rate code to a high level, low repetition rate code, in which elements of the convoluted coded signal are successively stored in a first memory such as a tapped delay line.  The stored code is sampled at tap location intervals defined by the high level code to obtain a set of first samples.  The first samples are then translated, each with a polarity coefficient determined by the high level code at the tap locations.  The translated first samples are then summed, and fed successively into a second memory such as a tapped delay line adapted to store the summed first samples.  The summed first samples are sampled at second tap location intervals defined by the lower level code to obtain a set of second samples.  The samples of the lower level code are translated each with a polarity coefficient determined by the lower level code at the second tap locations.  The translated lower level code is then summed in an adder to obtain an output signal.  The sequence is continued for all the code levels in the signal.
