Abstract: Abstract of the Disclosure A new saddle clamp comprises a U-bolt and a saddle providing complementary semicircular bight portions that embrace corresponding portions of a circular cross-section cylindrical member to be clamped so that when such a member is interposed between them it is surrounded   360 degrees of its circumference.  The nuts employed with the U-bolt engage downwardly-inwardly inclined nut-receiving surfaces formed around apertures in the saddle through which the U-bolt legs pass, and as the nuts are tightened they slide downwards on these inclined surfaces and the bolt legs are moved toward each other for uniform clamping sealing pressure around the cylindrical member. It is found essential that the planes in which these nuts slide-are sufficiently spaced from the common diametric plane that they do not intersect the cross-section of the cylindrical member being clamped since, if they do, a sufficiently rigid circular cross-section cylindrical member, such as a steel automobile exhaust pipe, can act as a reaction member to spread the legs apart and prevent the desired uniform sealing circumferential pressure.  Prior attempts to provide such complete circumferential sealing have not been successful owing to inherent defects in the geometry of those prior proposals, which are avoided by the clamps of the invention.

Abstract: SODIUM FILLED FLEXIBLE                     TRANSMISSION CABLE            ABSTRACT OF THE INVENTION         A corrugated flexible thin copper tube filled with sodium has a resilient flexible core along the axis thereof so arranged that it will contract and expand to take up the force of thermal expansion and contraction of the sodium.          Since the coefficient of expansion of the sodium and copper are different, the absorption of this differential in force by the core prevents rupture of the copper tube and the formation of voids and hot spots within the copper tube.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to safety-type ski bindings which per-mit the boot and ski to separate when the force applied exceeds a safe level, and which incorporate an automatic boot-to-ski return capability. It is common practice to couple a ski boot to a ski with a safety binding that allows the boot to separate from the ski upon the application of a force which would otherwise pose a risk of injury   A wide variety of bindings has been provided, including a type which represented a sub-stantial improvement over conventional ski binding design, in that an extensible-retractable cable serves both as a link between the boot and the ski, and as a ski-retaining leash.  However, there is a need for a ski binding similar to this invention, but having simpler construction and a lower cost.  The present invention fills this need by providing an improved binding which permits safety separation of the boot and ski and which has an automatic boot-to-ski return capability.  A soleplate for detachably mounting the ski boot is connected to the ski by an elongated, elastic leash that stretches to permit their separation and elastically contracts to draw them back together.  Rigid links on the ends of the leash form portions of the force-applying link between the boot and ski and engage cooperating structure on the soleplate such that the retention force between the boot and ski is higher when they are in close proximity to one another than when they have separated.

Abstract: METHOD OF CORRECTING THE VOLTAGE COEFFICIENT OF RESISTORS     IMPLANTED OR DIFFUSED IN A SEMICONDUCTOR SUBSTRATE                         Abstract A method and structure for correcting the voltage co-efficient of resistance (VCR) of a resistor in a semicon-ductor body is described.  The resistor may be diffused or ion implanted of one conductivity and formed in an isolated layer of the opposite type of conductivity.  The layer is typically an epitaxial layer.  A potential V1 is applied to one end of the resistor and a potential V2 being applied to the opposite end.  The method provides means for controlling variations of the potential differ-ence between the resistive region and the epitaxial layer, either to minimize them or to cause the distortions gen-erated by such variations to be compensated for by equal distortions of opposite directions, such that the overall distortion will be equal to zero.  There is provided cir-cuit arrangement to cause the potential of the epitaxial layer to reach a suitable value, preferably a value that varies in the same manner as the average value of the resistor whose VCR is to be corrected.

Abstract: ABSTRACT         In an oxide isolated semiconductor structure having an epitaxial layer formed on a monocrystalline sub-strate, a buried, laterally extending, PN junction in said structure, and oxidized isolation regions extending through said epitaxial layer to said PN junction, thereby to form a plurality of electrically isolated pockets of semiconductor material, a dopant is located in those regions of the semi-conductor material directly adjacent the oxidized isolation regions.  This dopant is often referred to as the field predeposition.          The processes which result in the subsequent formation of insulating material to create isolated epitaxial pockets also result in the formation of a conductive buried region resulting from that portion of the field predeposi-tion between the epitaxial pockets and portions of the wall of the insulating material.  If desired, a collector sink then may be formed in the epitaxial pocket without disrupting the function of the conductive buried region.  Among other embodiments, the conductive buried region may function as a collector sink bypass to allow manufacture of smaller memory circuits than those heretofore available.

Abstract: ABSTRACT OF THE DISCLOSURE   Electric power is generated from a non-uniformly operating energy source such as wind or water waves by driving hydraulic pump means by a wind wheel or a bobbing float.   The pump feeds hydraulic medium into a cylinder to raise a piston loaded by a weight.   When the weight rises above a predetermined level, the medium is fed under its constant pressure to drive an hydraulic motor connected to an induction generator. Because the generator is driven at constant power (though intermittently) it can be connected to the public mains supply, eliminating the need to store power, without sophisticated interface arrangements.  A second generator connected to a resistive space or water heating load can be cut in at higher energy levels.  The hydraulic pump can be arranged to extract power from the source in the most efficient way.

Abstract: SOLENOID APPARATUS Abstract of the Disclosure Solenoid apparatus.  First and second electrical windings are supplied current and the current flow through each of the wind-ings induces respective magnetic fields the strengths of which are functions of the average current flow therethrough and the mag-netic fields combine to produce a net magnetic field.  An armature is movable in either of two directions between a first position and a second position through a predetermined number of discrete inter-mediate positions.  The armature is biased toward one of the inter-mediate positions constituting a reference position and the posi-tion of the armature at any one time is determined by the strength of the net magnetic field and a biasing force on the armature.  A current source supplies current to the windings and the current source is controllable to vary the average current flow in each winding to produce movement of the armature from one position to another.  The average current flow in each winding is variable be-tween a minimum and a maximum value in steps and the predetermined number of intermediate positions to which the armature is movable corresponds to the number of these steps.
