Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to vibratory material handling apparatus and more particularly to a dual exciter system drive for vibrating the apparatus wherein the exciters are positioned on either side of the center of gravity of the apparatus and direct vibrations at obtuse and acute angles, respectively, through the center of gravity of the apparatus, the arrangement being such whereby the vibratory force exerted by each exciter may selectively be varied so as to cause the apparatus to vibrate vertically, or displaced from the vertical, so as to convey in one direction or the opposite direction.  The arrangement is such that the spring system connecting the exciters to the material-handling apparatus acts as isolation springs when the vibration generator associated therewith is inoperative, and as tuned natural frequency systems when the vibrator is actuating.  The invention also provides a shakeout screen and sand lump breaking apparatus combined into a single unit, thereby providing an apparatus particularly useful in removing foundry sand from castings and breaking down lumps in the sand to permit the reuse thereof.

Abstract: case 781014 PIPE ANCHOR Abstract of the Disclosure Pipe anchor for anchoring pipes to structural members and particularly for anchoring air lines and train pipes to structural members in the underframes of railway cars. Each anchor is a combination of three cooperating parts, namely, an adapter, a base, and a clamp. The adapter is the part that is attached to a structural member preferably by welding. The base is in the form of a saddle which seats on the pipe-engaging section of the adapter and has opposed sides which embrace a pipe on opposite sides and terminate in outturned, inclined, longitudinal flanges. The clamp engages the pipe diametrically opposite from the adapter and has inwardly opening inclined, longitudinal channels adapted to slide over the outturned flanges and draw the three-part assembly into equi-spaced four-point embracing support contact with the pipe.

Un émetteur fournit un flux lumineux en direction d'un élément translucide préalablement appliqué de façon prédéterminée contre la zone de peau à étudier et un récepteur mesure le flux lumineux transmis à partir de l'émetteur par transparence à travers l'élément translucide. L'interprétation de la mesure est effectuée par comparaison à la mesure obtenue pour un état de référence de l'échantillon translucide.  L'émetteur de flux fournit un faisceau modulé à une fréquence fixe et le récepteur de flux est associé à un circuit pour ne mesurer que le flux reçu qui a la fréquence de modulation de l'émetteur en fournissant une tension de mesure fonction du flux reçu.  L'appareil est caractérisé par le fait que la tension de mesure d'un repérage est mémorisée à volonté et envoyée sur un amplificateur différentiel qui la soustrait de la tension de mesure d'un repérage suivant pour fournir la tension donnant lieu à une lecture de la valeur mesurée.

Abstract: Steering System With Interlock Valves Abstract The drives of a vehicle are each driven by a pump and motor of a hydrostatic transmission. A servo-system associated with each pump is adapted to be controlled by a steering arrangement for selectively rotating the drives relative to each other. An interlock valve is associated with each steering arrangement to stop the drives of the vehicle when steering pedals thereof are both depressed into certain positions of operation.  Thus, the operator of the vehicle is prevented from placing the vehicle in an unwanted mode of operation, such as in reverse, when the operator desires another mode of operation, such as braking of the vehicle.

Abstract: A B S T R A C T                ZERO-CROSSING COMPARATOR WITH     THRESHOLD VALIDATION            In carrier and timing recovery systems for high performance data modems it is essential to employ threshold comparators and to be able to determine accurately zero-crossing instants. The circuit of the invention comprises a comparator with feedback which produces a positive transition of the comparator output in response to the negative zero-crossing transition of the input signal on condition that the previous half-cycle of the input signal has exceeded the positive reference threshold.  In a practical arrangement two comparators are provided together with a pair of bistable storage elements which produces a narrow pulse in response to the negative zero-crossing transition of an input signal provided that the input signal has exceeded the positive reference threshold applied to the second comparator.

Abstract: ABSTRACT OF THE DISCLOSURE       A composite drill collar for drilling bore holes in earth formations including a structural steel outer jacket having a lower end secure to a lower coupling connectable to a drill bit and an upper end secured to an upper coupling connectable to an adjacent drill collar thereabove.  An annular heavy metal core of sintered tungsten is disposed in the jacket and is held in compression therein by preleading the lower and upper couplings against the ends of the core, which places the jacket in tension, causing the jacket to contract and grip the periphery of the core.  The structural steel jacket has a thick wall to carry the bending, torsion, compression, tension and impact loads encoun-tered in the drilling operation, so that such loads are not carried through the core,  which has the purpose of increasing the overall density and mass of the composite drill collar, lessening considerably the tendency for a deviated well here to be produced.

Abstract: TEMPERATURE CONTROL IN HOT STRIP MILL  ABSTRACT OF THE DISCLOSURE               A method for controlling the temperature of a workpiece in a hot strip mill includes calculating temperature changes of the strip at each mill stand location by determining changes in workpiece deformation resistance and correlating the changes in deformation resistance and correlating the changes in deformation resistance to changes in temperature. Error corrections are made for changes in rolling speed.  The calculated temperature change at each mill stand is used to control water sprays positioned adjacent the mill stands.  A temperature sensor is placed downstream of the last mill stand to act as a check on the desired delivery temperature of the workpiece.  Temperature discrepancies from the temperature sensor are fed upstream to modify temperature corrections.

Abstract: ABSTRACT OF THE DISCLOSURE         A power steering apparatus includes an electric motor which drives a power steering pump.  A vehicle speed detector senses the speed of the vehicle.  A steering wheel rotation detector senses whether or not the steering wheel is being rotated.  At low vehicle speeds, a control assembly effects operation of the electric motor to drive the power steering pump at a relatively low standby angular velocity prior to intitiation of a steering operation.  Upon initi-ation and during of the steering operation at low vehicle speeds, the control assembly effects operation of the electric motor to drive the power steering pump at an angular velocity which varies as a function of vehicle speed.  When the vehicle is traveling at a relatively high speed, the control assembly causes. the electric motor to drive the pump at an angular velocity which is less than the standby angular velocity, that is, at a very low speed or at a standstill.  In one embodiment of the invention, rotation of the steering wheel is detected by sensing variations in the output from the power steering pump.  In another embodi-ment of the invention, rotation of the steering wheel is detected by sensing variations in the current conducted to the electric motor which drives the power steering pump.

Abstract: ABSTRACT OF THE DISCLOSURE         Tubing is made by continuously pulling steel strip at a predetermined feed speed from a supply, shaping the strip into a multilayer tube of a predetermined mass per unit length, and advancing the tube at the feed speed through a soldering station.

The contact outside the soldering station is dis-placed so that the spacing between the contacts is varied substantially proportionately with the product of the feed speed and the predetermined mass per unit of length of the tube.          Downstream of the soldering station the tube and solder are cooled to bond the tube together.
