Abstract: ABSTRACT OF THE DISCLOSURE            Improved electronic apparatus for weighing, computing a value and printing a label showing the weight, the price per unit weight and the computed value of each of a plurality of successive articles.  A microcomputer is supplied with the article weight from a load cell scale and with the price per unit weight either from a manual keyboard or automatically from a commodity plate in a label printer.  Tare weight is entered through a plurality of switches, each of which represents a different tare weight.  When one of the tare switches is actuated, a timer is started.  If a second tare switch is then pushed before a predetermined time interval is measured by the timer, the tare weight represented by the two switches are added together to obtain the total tare weight.  After the system corrects for zero error, checks for scale motion, compensates for the total entered tare weight and checks various interlocks, the microcomputer computes an article value and causes a label to be printed.  A digital indicator is provided for displaying the net article weight obtained from the measured gross article weight less the zero error correction factor and the total entered tare weight.

Abstract: Abstract of the Disclosure An intrusion detecting apparatus for an alarm system to signal breakage and movement of a door, window, or other movable partition comprising an elongated member forming an interior channel in which is disposed a switch actuating element for motion into and out of cooperative relation with a switch element supported on the channel.   The switch actuating element is connected to the parti-tion by a tensile member and is coupled to the elongated member by a spring so that movement of the partition from a predetermined position causes the switch actuating element to move out of coopera-tive relationship with the switch element and movement of the parti-tion back to the predetermined position restores the element to a cooperative relationship.   The tensile member may include a pair of electrical conductors which are connected to a device for detecting breakage of the partition.

Abstract: FLUID DISTRIBUTOR          ABSTRACT OF THE DISCLOSURE:    A distributor that supplies either a liquid or a gas to a bed of granular media, such as a sand filter, is divided by inclined interior walls into primary and secondary horizontal conduits that extend parallel to each other.  Gas metering orifices are positioned at an intermediate level in the inclined walls and liquid metering orifices are positioned beneath the gas metering orifices in the inclined walls. A liquid or a gas is supplied to the primary conduits, passes through the metering orifices into the secondary conduits and through dispersion orifices in the secondary conduits into the filter bed.  At least some of the secondary conduits are each connected to at least two primary conduits so that liquid can flow from one primary conduit through a secondary conduit to another primary conduit to compensate for inequalities of flow along the primary conduits.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus comprises self-contained potentiostatic device for the potential control of objects electrically connected via a controlled  change-over switch to reference (standard) electrodes and auxiliary electrodes, cathodes, in contact with electrically conductive media.  The apparatus includes a stand-by power source connected through the change-over switch to the objects.  Connected to the change-over switch control circuit is a means for the object potential.  The potentiostatic devices form, together with reference and auxiliary electrodes as well as with the objects, independent control circuits.  Provided the potential of one of the objects deviates from the preset value, the means for sensing the potential generates a signal for the change-over switch to connect the stand-by power source to this object.

Abstract: ABSTRACT OF THE DISCLOSURE    In a process for forming an extremely hard-wearing rubbing or bearing surface on a metal machine part, particles of hard grit, such as carbide grit, are deliberately forced into the surface using a resiliently-loaded tool, so that the surface becomes permanently impregnated with the hard particles.  During the operation the particles can conveniently be contained in a slurry that flows over the surface.  After impregnation, a lapping operation is performed on the impregnated surface using a fine carbide grit.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved timing control circuit for an automotive en-gine ignition analyzer is disclosed providing an improved sweep signal for the oscilloscope of the analyzer and providing both re-tard and advance lamp triggering signals for driving a strobe lamp associated with the analyzer.  The ramp generator incorpor-ated provides self compensation for changes in the engine speed of revolution by employing a phase lock loop with phase detector, in-tegrator and voltage controlled oscillator.  The oscillator pro-vides a ramp voltage for use as a sweep signal and input to the strobe lamp signal generator.                      The ramp voltage provides a sweep signal of substantially constant length while the engine speed varies over the range of idling to full speed.  The timing control por-tion for the strobe lamp used in adjusting the timing of an in-ternal combustion engine provides a signal which retards lamp triggering for setting ignition advance and a signal which ad-vances lamp triggering for setting ignition retard,  The circuit provides for advance and retard selection, the amount of advance or retard, and zero degree triggering for engines with various numbers of cylinders.  The lamp circuit employs the ramp voltage synchronized with engine timing, a reference voltage for setting the amount of advance or retard, and a comparator which provides a triggering signal for the lamp when the ramp and reference vol-tages match.

Abstract: ABSTRACT:     X-ray tubes with a magnetic bearing either have the disadvantage that the anode must be at earth potential, so that an asymmetric high-voltage supply is required or that - in the case of a symmetric high voltage - a relatively wide air gap is necessary which requires a high driving force and a bearing which has a certain amount of drawbacks. The invention provides an insulator between the anode which is at the high-voltage potential and the rotor which is at the earth potential, so that the air-gap between the rotor and stator can be relatively small and an effective mag-netic bearing is possible.

Abstract: TORSIONAL VIBRATION ISOLATING MOTOR MOUNTING  ARRANGEMENT AND METHOD OF MAKING THE SAME           Abstract of the Disclosure Motor mounting system is designed so that the torsional mode resonant or natural frequency is less than twice the frequency of the motor power supply divided by the square root of two  .  The illustrated mounting arrangements are "soft" with respect to torsional mode vibrations, and yet are "stiff" with respect to axial and tilting mode vibrations.  In one arrangement, lugs are formed preferably from a tough and strong sheet or strip material that is thicker and substantially stronger and stiffer (even in the radial vibration mode) than would usually be desirable from a torsional vibration isolation standpoint, but means are provided for promoting flexure in the vicinity of the parts of the lugs that will be subject to the most flexure or deflection.  These flexure promoting means may be in the form of tuning apertures formed along a preselected, longitudinally extending neutral axis of each lug so that the strength of the lug will not be objectionably compromised for axial loading conditions.  It is preferred to select the tuning means so that the cumulative effective spring constant (in pound-inches per radian) of the mounting lugs will be less than the quantity (2.84xIpx105), where Ip is the polar moment of inertia measured in pound-inches-seconds2.  Also illustrated are mounting band members and torsionally flexible arms that inter-fit one with another in a slotted interrelationship.  Ends of the arms are folded under a band member so that the ends of the arms are securely trapped by the band member against the outer peripheral surface of the motor.  This technique assures that the motor will remain supported by the band member and arms, and minimizes the degree of weld or other fastener strength that would otherwise have to be provided between the arms and motor.
