Title: Method and an arrangement for the compensation of  inertia forces in the indexing movement of a  machine element
Inventor: ANDERSSON PAER M
IPC: B65B65/04
Filed: 1979-10-24
Granted: 1982-06-15
Abstract: ABSTRACT     When machine elements having a large mass shall be indexed, i.e. subjected to short, quick rotating movements, very great acceleration and deceleration forces must be transmitted via the driving means of the machine. Due to vibrations occurring, increasing the stresses on the driv-ing means, this must be dimensioned accordingly. The present invention suggests a method and an arrangement for the compensation of the forces supplied and thus reducing the stresses occurred. This is performed by combining the indexing machine element with a cam disc which is affected by a number of spring-loaded cam followers, whereby the cam disc has such a shape that the cam follower decelerate and accelerate the cam disc following the desired movement pattern of the machine element.

Abstract: AC TO DC CONVERTER  FOR ANTISKID SYSTEMS     ABSTRACT OF THE DISCLOSURE         A circuit for converting AC signals from a wheel speed transducer to a varying DC level  indicative of the instantaneous rotational speed of the wheel of a vehicle.          The invention includes a squaring circuit receiving a sinus-oidal  input from a wheel speed transducer and producing a fixed amplitude square wave of a frequency equivalent to that of the sinusoidal input.  A pulsing circuit receives the square wave signal and produces a series of fixed duration pulses of a frequency double that of the sinusoidal signal.          These pulses are applied to an integrator which produces a DC output of an amplitude characteristic of the frequency of the sinusoidal input.  The integrator has a characteristic phase lag associated therewith resulting in a tendency of the phase of the superimposed AC output, caused by cyclic changes in the frequency of the transducer output, to lag the phase of the associated wheel speed change.  A lead net-work is designed into the integrator to compensate for such phase lag and to cause the instantaneous amplitude of the DC output to more closely correlate with the associated change in wheel speed.

Abstract: ROTARY ROCK BIT SEAL RECESS WASHER          Abstract of the Disclosure A sealing system for a rotary rock bit retains lubricant inside the bit and acts as a barrier to the pulverized cuttings and other materials in the borehole to prevent the materials from entering the bearing area through the cone mouth opening of the rolling cone cutter.  A protecting washer is positioned outside of an O-ring seal element in the gap between the base of the rolling cone cutter and the body of the earth boring bit.  This protects the O-ring seal element from the hostile drilling environ-ment and increases seal life.  During assembly of the bit, a gauging station is established to measure the size of the gap that will exist when the rolling cone cutter is installed on the bit body.  Protecting washers are provided in numerous thicknesses.  Upon determining the size of the gap, a washer is selected that will allow the gap to be narrowed to a size that will restrict passage of most of the abrasive particles found in the drilling fluid.  The protecting washer is pressed into a recess in the cone mouth opening of the rolling cone cutter.

Granted: 1981-02-17
Abstract: SIGNAL CODING FOR TELEPHONE COMMUNICATION SYSTEM ABSTRACT A telephone communication system reversibly converts input signals into adaptive delta modulated (hereafter ADM) signals and then into pulse code modulated signals. In one embodiment, an encoder of a telephone communication system receives analog signals, for example voice signals, in a com-parator which also receives an analog signal from an integra-tor for periodically providing ADM signals. The ADM signals are provided to a pattern detector responsive to predetermined patterns of the ADM signals to supply a step size increase or decrease signal to the integrator which then generates the analog signal compared with the input signal for forming the ADM signals. Each signal from the pattern detector is a linear pulse code modulated (hereafter LPCM) signal representing a signal increment corresponding to that represented by the ADM signal. Each LPCM signal increment is then added to the total of each preceding LPCM signal increment to form LPCM signals representing the input analog signal. The LPCM signals are then periodically sampled and each sampled LPCM signal converted into a corresponding compressed pulse code modulated (hereafter CPCM) signal for switching and further transmission. In a receiving path of the embodiment, a converter converts input CPCM signals into LPCM signals. Each LPCM signal together with a locally generated signal repre-senting the preceding LPCM signal is provided to a digital comparator which forms an ADM signal encoded in response to the relative magnitudes of the input and generated LPCM signals. The ADM signals are then provided to further means controlled by patterns of the ADM signals for providing a pattern controlled signal to an integrator which integrates the pattern controlled signal into an analog signal corre-sponding to the CPCM signal input to the receiving path of the embodiment. -2-

Abstract: ABSTRACT OF THE DISCLOSURE   The invention relates to an electronic photograph apparatus.  The apparatus comprises a charger adjacent to a photosensitive body, a retainer for image forming particles which is close to or in partial contact with the photosensitive body, a particle supply for supplying the particles to the retainer, and a single layer producer adapted to give the image forming particles forces which are not sufficient to remove from the photosensitive body the image forming particles directly attached to the photosensitive body, but are sufficient to remove the image forming particles attached thereto in subsequent layers.  The image forming particles can be evenly scattered into a single layer on the photosensitive body.          Even if the photosensitive body is carried at high speed, the scattering operation can be effectively carried out.          In addition, starting and stopping the scattering opera-tion of the image forming particles can be easily performed and the amount of the image forming particles consumed can be reduced.

By means of a perforated wall of a conduit or line the compressed air is blown into a dosed quantity of liquid soap located within a mixing chamber, to thereby form a coarse bubble lather or soap foam which subsequently is blown through a porous body, homogenized and compacted.  Different embodiments of the apparatus can be realized and it is particularly suitable for use as a foot actuated structure and for producing hot lather for shaving.  A preferred construction contains an intermittent-ly operated heater for preheating the compressed air, to thereby accomplish a particularly effective generation of hot lather.  The apparatus has the advantage    of increased economy owing to its reduced consumption of liquid soap and can be faultlessly hygienically operated and is especially environmentally protective.

Abstract: Abstract Digital dwell circuitry for a spark and dwell igni-tion control system is disclosed.  Maximum advance and reference sensors are utilized to produce pulse transi-tions which determine positions of maximum and minimum possible advance for spark ignition with respect to the position of the engine crankshaft.  For each maximum advance sensor pulse transition a main counter starts a sequential running count of speed independent clock pulses wherein the maximum count obtained by the counter is related to engine crankshaft speed.  The running and maximum counts of the main counter are utilized by dwell circuitry to determine the time prior to the next maximum advance pulse at which spark coil excitation should occur.  The main counter running count also determines several inputs to a read only memory (ROM) circuit whose output controls a rate multiplier.  The rate multiplier receives input clock signals, provides selective fre-quency division for these clock signals in accordance with the ROM output, and the output of the rate multi-plier is coupled to an accumulator means whose accumu-lated count is utilized to determine the occurrence of spark ignition by terminating spark coil excitation.
