Abstract: ABSTRACT OF THE DISCLOSURE     A current mode operational rectifier has an output terminal connectable as a DC current source of a predetermined polarity, and comprises a high gain amplifier having an inverting input terminal for receiving an input signal current from an AC current source and two alternative transmission paths for providing full wave rectification.  The first transmission path includes a first transistor having its base connected to the output terminal of the amplifier and its emitter and collector connected between the out-put terminal of the rectifier and the input terminal of the amplifier. The first transmission path conducts DC current to the output from the input terminal of the amplifier at an instantaneous level substantially equal to the instantaneous level of the input signal when the input signal is of a first polarity.          The second transmission path includes matched second and third transistors.  The second transistor has its emitter and collector connected between the input and output terminals of the amplifier while the emitter and collector of the third transistor are connected between the output terminal of the amplifier and the out-put terminal of the rectifier.  The second transistor conducts the input signal from the input terminal of the amplifier to the output terminal of the amplifier and the third transistor simultaneously conducts current to the output from the output of the amplifier at an instantaneous level substantially equal to the instantaneous level of the input signal when the input signal is of a polarity opposite that of the first polarity.

Abstract: ABSTRACT OF THE DISCLOSURE      METHOD OF FABRICATING DOUBLE-CURVATURE SHELLS      A method of fabricating double-curvature shells from meridional petaloid sections consisting in that the prefabrica-ted meridional petaloid sections are joined consecutively with one another in a number required for making a shell. The meri-dional petaloid sections are made from a flexible material and in the process of their joining they are successively coiled into a spindle-shaped roll for storage and transportation and the double-curvature shell is made by applying an axial force to at least one of the roll ends for uncoiling the roll and si-multaneously imparting a longitudinal curvature to said sections after which the first and the last sections are joined with each other. The method according to the invention permits fa-brication of high-quality double-curvature shells of any volume from any flexible material, it is highly efficient, calls for low expenditures of labour and funds, is simple and convenient in realization.

Title: Workpiece conditioning grinder  control system

Abstract: TITLE          WORKPIECE CONDITIONING GRINDER SYSTEM            ABSTRACT OF THE DISCLOSURE         An elongated metal workpiece such as a slab or bil-let is moved longitudinally beneath a grinding head by a reci-procating car mounted on an elongated track.  The car receives a billet from a charging table or other loading device, recip-rocates the billet beneath the grinding head for a plurality of grinding passes, and then delivers the finished billet to a discharge table. The grinder head includes a rotating grinding wheel mounted at the end of a first arm which is pivotally se-cured to one end of a pivotally mounted second arm.  A hy-draulic actuator extending between the frame and the first arm controls the grinding force exerted by the grinding wheel on the workpiece. One end of the actuator is connected to an ac-cumulator which provides a constant upward bias to the arm while the pressure in the other end of the actuator is varied in accordance with a pressure control signal.  The pressure control signal is derived from both a calculated torque com-mand indicative of the grinding force expected to produce a grinding torque corresponding to the torque command and a torque error signal which is a function of the deviation of actual torque from the torque command in order to maintain the grinding torque substantially constant.  The car may be recip-rocated so that the grinding wheel travels beyond the end of the workpiece with the hydraulic actuator being locked to hold the position of the wheel constant.  The grinding force may be limited to a preset maximum by allowing hydraulic fluid to flow from the actuator to raise the grinder head as grinding force exceeds the limiting value.  Grinding wheel vibration is limited by clamping the second arm to a massive, rigid founda-tion during each grinding pass thereby limiting the movement of the grinding head to a single degree of freedom.  The grinder system may be operated in either a manual spotting mode in which the positions of both the car and grinder head are manually controlled but maximum grinding torque is lim-ited, a manual skinning mode in which the position of the car is manually controlled but the grinding force exerted by the grinding wheel on the workpiece is automatically adjusted to maintain the grinding torque proportional to car speed but no more than a preset maximum, and an automatic skinning mode in which the car automatically reciprocates between the ends of the workpiece and the grinding force is automatically adjusted to maintain the grinding torque proportional to car speed but no more than a preset maximum.

Viel ABSTRACT OF THE DISCLOSURE       An improved rock windrower which includes a frame assembly, a reel adapted to be rotated within the frame assembly and having a plurality of windrowing teeth extending therefrom.  The frame and reel are adapted be angularly disposed relative to the draft direction of a towing vehicle.          The improved windrower features disposition of the implement teeth in a direction substantially parallel to the draft direction of the towing vehicle upon impact of the teeth with the ground.  Such an angle results in a full opening between adjacent teeth which in turn permits cleaner rock windrowing and further provides additional strength.  Another feature of the improved windrower includes the provision of a pair of wheel assemblies that are angularly disposed in the draft direction of the towing vehicle and which may be placed at any desirable position on the rear frame of the windrower during a windrowing operation by means of a pair of easily secured bolt hole plates.  An auxiliary pair of bolt hole plates are associated with each of the wheel assemblies for securing the latter to the front and rear frames in any desired position during the transport mode of the windrower.          The tongue assembly of the windrower also features a dual bolt hole plate construction for use both during the windrowing and transport modes of operation.

Abstract: ABSTRACT           Apparatus for processing domestic and industrial trash and garbage to recover the components that have fuel values by moving the trash and garbage through a fluid bed where it is shredded to a desired size while in the fluid bed, and subsequent-ly causing it to flow in an air lift at a low velocity so that the recoverable light weight components can be separated from the heavy components and collected through a cyclone separator, the heavy components being carried off by suitable conveyor means. The apparatus embodies a system of air moving means and conduits with control valves so that the fluid bed separator is operated at a negative pressure to assure a dust free environment for the apparatus and obtain an even distribution of the shredded material in a moving air stream at a low velocity so the material will separate on the difference in specific gravity, assisted by air elutriation.
