Abstract: ABSTRACT OF THE DISCLOSURE      A      process for extracting, concentrating, and isolating nickel and cobalt from aqueous solution thereof.          A cobalt and/or nickel bearing solution is contacted with an extractant comprising a substantially water immiscible organic solvent containing solubilized mercaptide anion to form water insoluble cobalt and nickel mercaptides in the organic phase.  The organic phase is then separated from the raffinate and contacted with an alkaline solution and carbon monoxide to produce nickel and cobalt carbonyl compounds.  Typically, the nickel carbonyl produced is gaseous Ni (CO)4 which may be easily isolated by known methods from other components in the off-gas stream.  Pure nickel metal is then obtained from the nickel tetracarbonyl by known methods.          The cobalt carbonyl compound produced is typically water soluble carbonyl cobaltate ion, Co(CO)?4, which may be oxidized to form water insoluble cobalt carbonyl compounds.  The stripped extractant, the cobalt and nickel-free raffinate, and the carbon monoxide from the decomposition of carbonyl may be recycled.

Abstract: ABSTRACT OF THE DISCLOSURE           The force transducer includes an essentially sym-metrical, beam flexor of generally rectangular, platelike construction, one of the edge surfaces being provided with a strain gage.  A continuous, Z-shaped slotlike passage is formed through the thickness of the beam flexure between its major surface areas, with one cross bar of the "Z" preferably parallel to the edge carrying the strain gage.  An enclosing housing supports the beam flexure via a pair of pin members extending through openings provided in the beam flexure and located at one side of the diagonal portion of the "Z". Ex-ternal forces are applied to the beam flexure via a further pin member extending through an opening provided on the other side of the diagonal portion of the "Z".  Forces to be meas-ured are applied substantially solely in planes parallel to the major surface planes of the beam flexure.  An undersized free-floating pin is located within an enlarged bore provided in the center of the diagonal portion of the "Z" to prevent both operation beyond the most accurate range and damage in the event of exposure to an excessively large force.

Abstract: ABSTRACT OF THE DISCLOSURE   A body of a butchered animal suspended at its hind legs by suspension conveying means is conveyed by means of a conveying table to a station for splitting the body into two halves along the spine, where the body and the conveying table become stationary and the body is turned through 90 degrees in a splitting position between body supporting means and pusher means which is indexed with the conveying table, so that the back of the body will face the body supporting means.  Then, sensing means senses the presence of the body in the splitting position and actuates the body supporting means to bring it to an operative position to support the body, while the pusher means is also actuated to urge push rods extending through the  conveying table into contact with the body to clamp it tightly to the body supporting means.  At the same time, driving box mounting a saw therein and located behind the body supporting means moves downwardly along a guide frame from its uppermost position and the saw is automatically rotated to cut into the body, while water is splashed against the body, to thereby complete the splitting of the body when the driving box has reached its lowermost position.  Upon completion of the splitting of the body, the driving box means is moved upwardly to its uppermost position and the body supporting means and the pusher means are returned to their inoperative position, while the conveying table is restored to its original position.          A body splitting operation can be perform efficiently with a minimum of manual attention in a sanitary condition.

Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to an improved weighing scale with a load cell of simple construction which overcomes the problem of an eccentric load acting on the beam so as to result in measurement error.  It comprises a beam which is integral with and extends inwardly and horizontally from a perpendicular base which is secured to a fixed base, defining a parallelogram having four strain gauges bonded thereto.  A load transmission section is integral with and extends inwardly and horizontally from a perpendicular moving side for bearing a load.  Arms connect the upper and lower portions of the base side to those of the moving side, defining an integral parallelo-gram.  A pivot shaft couples the tip of the beam to the load transmission section.   The beam and the arm body are integrally shaped with a high level of accuracy and the beam has two flanges for fitting of a bellows for the protection of strain gauges bonded to the beam.  The load cell is capable of pre-venting the application of excessive load to the beam by way of restrictive excessive movement of moving parts and of synthe-tically adjusting the temperature characteristics of electric circuit components wired electrically to the strain gauges.

Abstract: Abstract of the disclosure Heat processing of pulverized brown coal is carried out in two stages. In a chamber for the first-stage heating brown coal to be processed is heated to a temperature of thermal decomposition thereof with the formation of a solid matter and a vapour and gas mixture. The resultant vapour and gas mixture is removed to be purified and condensed to obtain gaseous and liquid products. In a chamber for the secondstage heating brown coal in the form of solid matter is heated to cause additional decomposition thereof which results in the formation of a solid product and a vapour and gas mixture. The resultant vapour and gas mixture together with a part of the resultant solid product is fed through a return conduit into the chamber for the fist-stage heating of the brown coal. The develop a draught which causes the solid product particles to move along the return conduit, the latter is provided with a means for feeding a gaseous heat carrier.      With practically the same power consumption as in the prior art methods, the yield of the vapour and gas products grows by about 25-30% depending on the type, grade and particle size of the brown coal being processed.

Abstract: ABSTRACT     This invention relates to a novel non-interruptible power system (NIPS) comprising an A.C. generator that pro-duces A.C. at a constant frequency and voltage regardless of the electrical power supply to a driving motor for the generator.  The A.C. generator comprises at least one field core with a cylindrical surface with a layer of magnetizable permanent magnet material thereon, and a slotted armature, relatively rotatable to the field core, having a cylindrical surface Juxtaposed to the cylindrical surface of the field core.  An excitation coil in the armature is disposed to have A.C. passed through it so that it magnetizes the layer of magnet material in the field core into a pattern of magnetic poles.  Main A.C. power windings in the armature generate A.C. during rotation.  A novel feature comprises placing in selected slots in the armature (1) supplementing windings for generating A.C. for the excitation coil and (2) modifying windings energizable with current to control the remanent flux in the layer of magnet material.  In generators with several field cores and armatures, there are provided in selected slots in each armature leading or lagging windings or both whose A.C. output may be combined with that of the main power windings to give an A.C, output with low total harmonic distortion.  If power to the driving motor fails, the rotational energy of the generator keeps producing the desired constant voltage and frequency for a prolonged period.

Abstract: ABSTRACT:               The invention relates to a shaving apparatus having a shear plate with hair-entrance apertures and a cutting member which is rotatable relative to the shear plate, which cutting member is substantially constituted by a central body which provided with cutters at the circumference.              Especially at increasing numbers of cutters per cutting member and when the number of hair-entrance aper-tures is a multiplicity of the number of cutters, there is a risk that during use of the apparatus several hairs are cut simultaneously, which presents an undesired peak load to the drive mechanism of the apparatus. In order to reduce this risk, it is proposed to arrange the cutters in groups with equal intervals between the cutters of one group, which intervals differ from the intervals between two adjacent cutters of different groups.

Abstract: Abstract of the Disclosure The present invention relates to a method of operating a raster-scan-mode-of-operation electron beam lithographic system to irradiate a workpiece that is supported on a continuously moving table.  The method is characterized by the step of generating deflection signals that in effect exactly compensate for both table motion and the regular raster scan deflection signals of the system to cause the electron beam to dwell only on each of multiple selected portions of a low-density pattern for a time that is substantially greater than the time during which each portion would be exposed during regular raster scanning of the surface of the workpiece.
