Abstract: HOOK ASSEMBLY                   ABSTRACT OF THE DISCLOSURE       A swivel hook has a hook member with a frustoconical projec-tion terminating in a cylindrical extension of diameter less than the smaller diameter end of the frustoconical portion.  The mounting member for the swivel hook has a frustoconical hole into which the frustoconical projection is fitted and is removably mounted to a wall mounting element.  The elements of  the swivel hook are adapted to be cast of a metal or molded of a plastic, in such a manner that the bearing surfaces of one of the elements forms a part of the die for the bearing surface of the other element.  During the casting or molding process, the cylindrical extension is beyond the frusto-conical hole, and the elements are moved relative to each other following casting or molding to move the cylindrical extension into alignment with the frustoconical hole.

Abstract: ABSTRACT A method and apparatus is provided for producing wood pulp in a wood grinder.  Wood is fed to a grindstone against which the wood is pressed by two wood-supply shafts, each of which has a pressure gate.  The grindstone is mounted in a pressure-tight housing into which water is fed.  The wood is ground at a positive pressure and at water temperatures above 100°C.  The pulp produced is collected in a trough under the grindstone.  A draining worm located in or after the trough drains the pulp to concentrate it and recover water under pressure.  A water-drainpipe is connected at one end to the worm and at the other end to a pressurized water tank.  A return line connects the water tank to the housing to deliver the recovered water to the grinding area.  The concentrated pulp is relieved to atmospheric pressure after passage through a pulp-discharge line.

Abstract: DUAL SPEED CONTROL CIRCUIT FOR POWER FLOW          THROUGH AN INVERTER     ABSTRACT OF THE DISCLOSURE         A control circuit for a force-commutated inverter con-nected intermediate a regenerative DC power source and a power grid, the power source/inverter combination operative to supply AC electrical-energy to, or receive AC electrical energy from or adjust the power factor of, the AC electrical energy of the power grid.  The control circuit of the present invention varies the real power component and the reactive power compo-nent of the electrical energy flowing between the electro-chemical cell and the power grid through the use of two feed-back loops with separate time constants.  The first feedback loop allows for the independent control of the magnitude and direction of both the real power component and the reactive power component of the AC electrical energy flowing to or from the power grid.  The first feedback loop also has a relatively slow time constant so that the power flow between the DC source and the power grid is substantially unaffected by transients.  The second feedback loop has a fast time con-stant for rapidly adjusting the effective magnitude and phase of the voltage waveform from the inverter to compensate for instantaneous or short duration voltage surges which periodi-cally appear on the power grid.

Abstract: ABSTRACT          "Method of and device for examination by means of ultrasonic beams."     A method of and a device for ultrasonic examination of an object by means of a row of N electroacoustic transducers. Each time a group of M transducers (M ?

These M transducers are first included in transmission networks, transmission signals then being applied to the converters; subsequently, they are included in receive networks, receive signals then being applied to a display device. The transmission and/or receive signals are multiplied by weighting factors between 0 and 1. The sum of the weighting factors during transmisison may deviate from that during reception. During transmisison and/or reception, at least two different combinations of weighting factors are used, the sum thereof being each time the samR. The scanning line density can thus be substantially increased.

Abstract: DISTRIBUTING FRAME AND TERMINAL BLOCK MEMBER ASSEMBLIES         Abstract of the Disclosure A distributing frame having a terminal block member attached to it by a mounting bracket which is secured either to the block member or a frame member by one of two interconnected mounting parts lying in different planes. Loosening of screw securing means passing through one of the mounting parts allows for relative movement of the mounting bracket and the respective member to reposition the securing means in the other mounting parts.  This causes change in the angle of orientation of the bracket and respective member and thus causes the block member to pivot on the frame member.  To connect electrical wiring to terminals on each side of the block member, it may thus be mounted in one of two alternative positions without removal from the frame while using a simple, one-piece bracket.                                       - i -

Abstract: ABSTRACT OF THE DISCLOSURE A soil cultivating implement or machine has a tined rotor mounted on a frame for rotation about an axis transverse to the intended direction of movement of the implement, and with the tines penetrating the ground in use.   The tines are arranged to enter the ground in the same sense as the forward movement of a vehicle driving the implement.   The rotor is connected either to a second tined rotor which rotates faster than the first rotor which rotates in the same direction as the wheels of the vehicle but at a lower peripheral speed than the speed of movement of the implement over the ground.   The ratio of the rotational speeds of the two rotors is between 2:1 and 4:1.   Each motor has a rotor shaft with a plurality of axially spaced mounting flanges, the the tines being bolted to the flanges and extending generally tangentially of the rotor shaft.
