Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a plant for the pressure gasi-fication of fine-particle fuels, in which the fine-particle fuel is fed to the reactor from a pressure tank having a level control ler, by means of a vehicle gas fed via a conduit, said fuel being fed via a fuel feed conduit, while the gasification agent is fed via another conduit in a predetermined ratio by volume according to the amount of fuel supplied.  me fuel feed conduit contains a system for measuring the fine-particle fuel present in a spe-cific cross-section of the conduit, said system being based on the principle of absorption of electromagnetic radiation by the fuel, and the measuring system is connected to a process computer which forms the reciprocal (U1) of the value (u1) obtained in the measuring system.  The conduit for supplying the major proportion of vehicle gas contains a system for measuring the volume supplied per unit of time and said system is also connected to the process computer and transmits the measured value to the latter in the form of a voltage (U2).  The computer is so constructed that to-gether with a predetermined comparison voltage (Uv) it forms the difference (U2 - Uv) and the product [U1 ? (U2 - Uv)] for all values of (U2) greater than (Uv) and in accordance with the value of the product [U1 ? (U2 - Uv)], controls the valves for the feed conduits for the proportion of vehicle gas which loosens the fuel in the pressure tank and discharges it therefrom, and the valve for the supply of gasification agent.

Abstract: ELECTROMAGNETIC WAVE RING RESONATOR                  Abstract of the Disclosure An electromagnetic wave ring resonator is disclosed including means to spatially rotate the electromagnetic field distribution of waves resonant therein about the direction of propagation of such waves to enable such waves to resonate with opposite senses of circular polarization, and means, including a laser amplifier medium, to provide different indices of refraction to resonant waves of the same sense of circular polarization as they pass through such laser amplifier medium in different directions.  With such arrangement the two mentioned means enable the waves to resonate with four different frequencies. In a laser gyroscope using such ring resonator the electromagnetic field distribution rotating means includes a catoptric arrangement which, together with the last-mentioned means, reduces the loss, scatter and linear birefringence associated with the ring resonator included in such gyroscope.  The last-mentioned means produces the Zeeman effect in the laser medium and efficiently provides different optical pathlengths for waves passing through such medium because the magnetic field vector of such waves interacts with the precessing atomic magnetic dipoles of the amplifier medium at the emission frequency of such amplifier medium.

Abstract: ABSTRACT:    A conventional fluid flow meter provides a single pulse output signal for each uncorrected unit volume flow.  A mono-stable multivibrator (MV) is triggered by said meter signal and provides a gating signal for a 1 MHZ oscillator to produce a pulse train.  A temperature sensor senses the fluid flow at the meter and controls the monostable MV so that the number of pulses in said pulse train is inversely proportional to the absolute temperature of the fluid flow.  A preset down counter derives from said pulse train a number representing the absolute temperature at the sensor.  A burst generator generates a fixed number of pulses related to a predetermined base tem-perature.  A divider divides said fixed number of pulses by said number representing the absolute temperature of the fluid flow and provides a single pulse output for each integer re-sulting from said division and stores the remainder from said division for use in the next division.  A register accumulates the number of pulses resulting from said division and repre-sents the corrected volume flow.  The above calculation is completed in a small fraction of the time period between meter pulses.  A solid state switch operates to supply power to said monostable MV and to enable said oscillator for a preset time period sufficient to permit said calculation to be com-pleted.  The switch then turns off the power supply and disables the oscillator until the next meter pulse occurs.

Abstract: COMBINATION FLYER-JUMPER AND METHOD OF MANUFACTURE OF SAME IN WHICH THE JUMPER/FLYER IS ASSOCIATED WITH A GEOPHYSICAL DATA ACQUISITION SYSTEM THAT PROVIDES DIGITAL DATA IN THE FIELD BEFORE RECORDING     ABSTRACT OF THE DISCLOSURE         The method and apparatus of the present invention are described in which connection (and disconnection) of a plurality of geophones associated with a digital seismic data acquisition system is greatly simplified without sacrificing flexibility as to the number of geophone flyers per station or the interval spacing per station and also without the addition of separate subcabling in the internal linkage of the flyers to the field digitizing equipment.  The apparatus includes a multiple-phone flyer-jumper connected to each channel of a remote data acquisition and telemetering circuit (RDATC).  The latter in turn is linked to a central control and recording station usually located in a truck.  Each RDATC acts in combination with a group of geophone flyers, say four, to store, amplify, filter, gain control and digitize analog data from the flyers and then telemeter the data to recording circuitry in the field truck.  In accordance with the present invention, each jumper-flyer includes a central multi-conductor cable segment of say N+1 conductors where N is an even greater positive number than two, such as 4, 6, etc., terminating at each of its ends in the central leg of a multi-armed connector.  A plurality of series/parallel connected geophones, say 9 in number are used in combination with the central segment.  At the end of the arms of each multi-armed connector pass another conductor cable segment (similar to the central segment, but called the "branch cable segment") in which only two fo the cables are actively connected to the selected conductor pairs of the central segment.  At the other end of each branch cable is a two pin-two recepticle hermaphroditic connector.  Each connector allows either (i) three geophone conductors of the central cable segment or (ii) at least the remaining conductor pairs, to be flexibly connected to outside circuits including the RDATC to actively transfer data from the internally based geophones, or from more remotely located geophones located adjacent to the flyers of interest, respectively.

Abstract: MULTI-SPEED PLANETARY DRIVE AXLE ASSEMBLY                Abstract of the Disclosure A two speed planetary drive axle assembly comprises a differential carrier fixed over and extending within a drive axle housing.  The carrier mounts a differential case connected by a pinion and ring gear to the engine driven propeller shaft.  The case contains a differential mechanism connected between two drive axle shafts and constitutes a carrier for planet gears constantly meshed with an internal ring gear rigid with the differential case. The sun gear is in the form of a sleeve concentric with one of the drive axle shafts and selectively movable between two axially spaced operative positions within the axle housing.  A fixed abutment is provided to limit axial movement of the sun gear in the direction of the differential mechanism to prevent the sun gear from contacting the differential mechanism.  Additional abutment means limit movement of the sun gear in the other direction.  The sun gear sleeve is thus positively stopped by the operating mechanism at each of the axially spaced operative positions.

Abstract: BUTTON FEEDING AND ORIENTING SYSTEM FOR SEWING MACHINES Abstract of the Disclosure The disclosure is directed to improvements in automatic mechanisms for feeding properly oriented buttons to the sewing station of a sewing machine, in preparation for sewing on a gar-ment.  The system utilizes a highly simplified pneumatic actu-ating system for both feeding and orienting the buttons.  The system of the invention is arranged to accommodate a multiplicity of mechanical operations involved in button feeding and orienting, utilizing a simple arrangement of two pneumatic actuators, which are energized in timed sequence by pulses of air derived from operation of the sewing machine.  In one of its most advantageous forms, the system of the invention derives the necessary timed energizing pulses of air from control air cylinders which form part of the basic sewing machine mechanism itself.  Thus, adapta-tion of a conventional industrial sewing machine to incorporate the button feeding and orienting system may be accomplished in a highly simplified and economical manner.
