Abstract: ABSTRACT OF THE DISCLOSURE     The same input signal is applied to each of the bases of a pair of amplifying transistors, while an output signal is produced at the emitter of one of the pair of transistors. The collector of the one transistor is connected to the emit-ter of the other transistor.  The junction point between the collector of the one transistor and the emitter of the other transistor is connected through a diode to a first DC power source of low voltage.  A second power source of high voltage is connected to the collector of the other transistor, thereby selectively supplying electric power to the one transistor in accordance with the signal level of the input signal.  An inductance element is connected in series with the diode to generate a counter electromotive force to prevent a reverse current from flowing through the diode during the cut-off state of the diode, thus providing a highly efficient amplifier with little distortion.

Abstract: ABSTRACT OF THE DISCLOSURE      The new and improved hull construction for a jack-up rig is disclosed.  In the preferred embodiment, a three legged jack-up rig is disclosed.  The rig is supported on three legs which extend through similar corner compartments having leg elevating equipment thereat.  Along the three sides of the triangular hull, side compartments of similar rectangular and or trapezoidal construction are located which encompass or enclose a central triangular compartment.           The side compartments are aligned in a strengthening direction.  The main side compartments have a rectangular area and hence lend themselves readily to crew quarters, machinery rooms, and the like.  The rectangular construction utilizes repetitive structural members and hence a limited number of identical structural modules is used.  The use of a central triangular module with side modules parallel to the sides of the platform provides major structural bulkheads for bearing the weight of the hull and the bending moments in the hull.

Abstract: ABSTRACT OF THE DISCLOSURE         A substantially planar slab has two opposite edges castellated in such fashion that two such slabs may be inter-engaged with the slabs in the same plane with the castella-tions of one edge of one slab interfitting the castellations on the other edge of the other slab.  The sides of the castel-lations are inclined in a direction not normal to the plane of a major face of the slab.  Such slabs are useful for lining containers for molten metal, and when forming such a lining all joint faces of the interengaging castellations not lying in vertical planes can be arranged to slope down-wardly away from the interior of the molten metal container. The thickness of the slabs, the angle of the castellations, the period of the castellations and the inclination of the slabs can be so chosen relative to the angle of repose of a loose fill of refractory material under the slabs that the loose fill particulate refractory material does not penetrate the joints between adjacent slabs:

Abstract: ABSTRACT OF THE DISCLOSURE      The invention contemplates a virtually hysteresis-free electromechanically actuated valve, wherein an electrical input current is converted into a substantially rectilineal force or displacement, using a single electrical coil and two spaced and oppositely polarized air gaps.  Similarly spaced, opposed parts of the coil are compliantly mounted for and constrained to move in the respective air gaps, the constraint being such as to develop substantially a unidirectional force and/or displacement which is in the plane of the gap-shrouded parts of the coil.  The actuating mechanism is described in the context of an hydraulic-valve, with incorporation of a viscous-damping feature.

Abstract: ABSTRACT OF THE DISCLOSURE             This relates to a method for facilitating the rapid and convenient installation and removal of the top section of a steelmaking vessel of a type that is rotatably mounted i.e. provided with trunnions.  The method involves providing the top section with lifting brackets and also providing a hinge connection between the top section and the vessel body.  During removal, the vessel body is rotated while lifting forces are applied to the brackets thereby causing the top section to be pivoted relative to the vessel body about the hinge.  This process is carried out in such a way as to cause the top section to be moved outwardly over the operating platform following which the top section is gently lowered onto such platform. Following this, the top section is disconnected from the vessel body at the hinge and the necessary repairs to the top section are effected.  Following repair, essentially the reverse of the above described procedure is carried out thereby to position the top section accurately on the body of the vessel.

Abstract: ABSTRACT OF THE DISCLOSURE In an electron accelerator having a target which is exposed to an electron beam for the production of x-ray deceleration radiation, a conical compensating member is arranged centrally within a cone pattern of the x-ray radiation.  The compensating member has a decreasing conical shape toward the target and merges into a cylinder portion.  Beam paths within the cylinder portion which are additional to those in a conventional purely conical compensating member are compensated by a recess positioned in a base of the compensating member having an appropriately selected depth, In another embodiment, a conically shaped compensating member is arranged within the cone-shaped x-ray pattern such that a tip of the compensating member is aligned away from the target and a base is aligned toward the target.  A collimator having a conical passageway surrounding the x-ray radiation has a groove for receiving the base of the compensating member so as to mount the same within the conical passageway of the collimator.

The device has increases in the concentration of those particular elements at the electrodes to which the respective constituents would migrate during a large number of set-reset cycles.  This lessens the decline in the threshold voltage caused by the electromigration of those constituents.  There is disclosed a layered structure in which a layer rich in one appropriate constituent is placed between the amorphous memory material layer and the respective electrode and another layer of material rich in the other constituent is placed between the amorphous material and the other electrode.  Specifically, there is disclosed a tellurium based chalcogenide as the memory layer.  A layer of substantially tellurium is placed between the amorphous memory layer and the positive electrode while the layer of germanium and tellurium in a ratio of approximately 1:1 is placed between the amorphous material and the negative electrode.

Abstract: ABSTRACT OF THE DISCLOSURE        A hollow arrow shaft is open at a first end. and is filled in, so that it is solid in the area of its opposite second end for a predetermined part of its length from its second end. Holes are formed through the shaft where such shaft is hollow, next-adjacent the solid part of the shaft. A trail-indicating dye material is provided in the shaft.  Feathers are affixed to the shaft extending from the area of the second end thereof where the shaft is solid.  A piston member is coaxially movably mounted in the shaft at the first end thereof and extends a predetermined distance out of the first end and a predetermined distance into the shaft.  A head part is mounted on the piston member at the end thereof extending from the first end of the shaft.           Thus, when the arrow strikes a target, the impact with the target forces the piston member back into the shaft thereby causing the dye material to gradually drip to the ground via the holes through the shaft to mark the trail of the target.
