Abstract: ABSTRACT OF THE DISCLOSURE       An improved sling construction for lifting heavy loads is disclosed.  The sling is formed by intertwining a multiplicity of three body part slings or subslings which in turn are woven from single cables in such a manner that they have a body having an eye at each end thereof.   The construction of the sling is such that when the particular application calling for such a sling is completed, it may be readily disassembled enabling re-use of the constituent subslings.   A second construction for lifting very heavy loads is also disclosed.

Abstract: PHN. 8969. 18-4-1978.    ABSTRACT :           A television camera comprising a control and setting stage for the beam current control of an electron beam in a pick-up tube. Via an substantially video frequency picture signal amplifier suitable for supplying the picture signal over substantially the entire amplitude range over which the pick-up tube generates the picture signal, via a coupling capacitor the picture signal generated by the pick-up tube is superimposed as a control voltage on the setting voltage for the control electrode of the pick-up tube. A stable beam current control without oscillations is the result.

Abstract: ABSTRACT              A method and apparatuses are disclosed for making shingles. The method consists of clampingly holding a block of material to be cut and conveying such block while it is clamped along a selected path through the clamping mechanism and causing relative movement between two cutting means which axe inclined relative to one another to firstly cut a shingle from the block tapering in one direction and followed by a second shingle tapering in the opposite direction.  The apparatus includes means for receiving and clampingly holding blocks as they are fed in sequence thereto and means to feed the block while it is clamped.  The block is fed into the path of two cutting mechanisms and upon relative movement of the clamped block and the cutting mechanisms, the first cutting mechanism cuts first one shingle tapering in one direction and the second mechanism thence cuts a second shingle from the block tapering in an opposite direction, the cutting mechanisms being inclined relative to one another providing the appropriate taper for the shingles cut thereby from the block.  The block clamping and feed mechanism includes two power driven spaced apart conveyors inclined in a direction toward one another in the direction of feed, progressively applying increased clamping forces to the block as it is moved therethrough toward the cutting mechanism.  The conveyors each have a plurality of driven rollers disposed parallel to one another and are driven in synchronism, moving the block incrementally in amounts corres-ponding to the thickness of shingle desired.  The cut shingles are conveyed to an edge trimming apparatus and are moved by conveying means through at least one trimming station having cutting means for trimming the edges of the shingle.  Upstream of the cutting means there is located a scanner that provides information to a computer that processes the information and actuates movement of the trimming saws to trim the edges of the shingle minimizing the amount of waste for each shingle,  Defect cutting devices are also provided for removing defects in shingles and they too are controlled by information provided by the computer.

Abstract: ABSTRACT OF THE DISCLOSURE           Equimolar amounts of phenol and formaldehyde may be prepared from oxygen and toluene.  The catalytic oxidation of toluene, when carried out in the presence  of acetic anhydride, forms phenyl acetate and methylene diacetate.  Pyrolysis of these two intermediates yields phenol and fomaldehyde.         Significant improvements in this process are achieved when the first stage of the reaction is carried out in the presence of MoO3.         In a further embodiment of this invention it has been found that Group VIII dithiosemibenzil compounds, part-icularly nickel dithiosemibenzil, serves as a superior pro-moter for the toluene oxidation reaction.

Abstract: ABSTRACT OF THE DISCLOSURE            A method and apparatus are provided herein for determining at least one component of a sample of a particulate or granular material, e.g., grain or seed, on the basis of a permittivity value of the sample.          The method involves the first and second steps of gradually introducing the sample in a movably mounted container and compacting the sample in the container to a predetermined degree by vibrating the container during the gradual  filling thereof with the sample.  The so-compacted sample in the container is then exposed to an alternating electric field.  A permit-tivity value of the compacted sample is then measured.  The component is then determined on the basis of the permittivity value, and the weight of the sample is also determined based on the natural vibrational frequency of the movably mounted container with the sample contained therein.

Abstract: ABSTRACT OF THE DISCLOSURE Determinations are made of the conditions in a fluid-containing well penetrating a fluid-producing sub-terranean reservoir by isolating an interval in the well which penetrates the fluid-producing reservoir, with-drawing fluid from the interval and determining conditions such as fluid composition, pressure build-up, and tempera-ture in the interval.  The interval is isolated with a packing member surrounding an open conduit means extending in the well from the top of the well to a location adja-cent the reservoir.  Fluid moves from the reservoir into the conduit means and is withdrawn from the conduit means through an opening in the conduit means above and adjacent the lower end of the conduit means.  Determinations are made by lowering measuring tools through the tubing string to a location in the well below the opening through which fluid is withdrawn from the conduit means.

The channel communicates with the main conduit by means of a first gap situated between the outlet of the main conduit and an inlet of the turbine wheel.  The channel also communicates with an outlet conduit disposed downstream of the turbine wheel by means of a second gap situated between an outlet of the turbine wheel and an inlet of the outlet conduit.  Most of the particles leave the gaseous media through the first gap.  Smaller particles which bypass the gap are deflected into the annular channel by the blades of the turbine wheel.
