Abstract: ABSTRACT OF THE DISCLOSURE         In large turbine machines, it is critical to bearing performance that the turbine rotor remain aligned with the bearing surfaces.  Misalignment can occur due to high thrust loads or thermal deformation.  The object of the invention is to ensure correct rotor-bearing alignment under all operating conditions.  The invention is a self-aligning bearing support structure capable of accommodating angular rotor misalignments.  The bearing support structure includes a bearing casing which transfers axial loads or thrusts to the bearing standard through a yoke attached to the bearing casing and to the bearing standard by pairs of axially oriented flex struts.  In combination with the axially oriented flex struts a transverse flex plate supports the bearing vertical load.

Abstract: ABSTRACT   This invention relates to a frame corner construction including two frame members butted together at a joint by a tensioning-eccentric connector, the two frame parts having boreholes extending perpendicularly to the joint for receiving a tension bolt, each frame part having at the end of its borehole a preferably round recess perpendicular to the borehole and open to one side face of the frame part, a round tensioning eccentric being turnably inserted into the recess of the one frame part for engagement with a clamping end of the tension bolt, the fastening end of which being held fast in the recess of the other frame part by means of a holder.  Presently known frame corner constructions of this kind suffer from certain disadvantages such as overly complex construction of the tensioning-eccentric connector requiring a high degree of skill, and high cost factor.  The invention seeks to overcome these problems by providing an easy and inexpensive frame corner construction.  The invention provides for holding fast the fastening end of the tension bolt with an abutment stop part which is fixed on the fastening end of the tension bolt, the length of which abutment stop part in the circumferential direction of the recess which receives the abutment stop part being greater than the diameter of the corresponding borehole.  Further the abutment stop part has an abutment surface which substantially corresponds to the shape of a corresponding circumferential wall of the recess, and the inner dimension of this recess in the axial direction of the boreholes corresponds approximately to the length of the tension bolt including that of the abutment stop part for adapting the tension bolt to be insertable into the boreholes from the recess which receives the abutment stop part.

Abstract: Abstract of the Disclosure:   In installations for the production of phthalic anhydride,  the reaction product is precipitated in a solid form on heat exchange sur-faces of separators, and is subsequently melted off again, by alternately cooling and heating the separators. The arrangement employed, according to the invention, for transferring the heat and for levelling out the tempera-ture profiles (in which, in the heating phases, there is a peak demand for heating steam, which impedes the useful generation of steam by the exothermic reaction), com-prises a heat transfer system consisting of three circuits at different temperatures.     A storage circuit (hot oil circuit) at a higher temperature is superposed on the heating circuit operating at a pre-determined temperature.     Using the hot oil circuit, the separators are provided, during the heating phase, with the heat required to melt off the reaction product. This superposition of 3 circuits at different tempera-tures produces a levelling of the steam requirement and hence allows more effective utilization of the excess steam.

Abstract: FOLDING SEQUENCE CONTROL FOR WING FOLD IMPLEMENTS  Abstract of the Disclosure A hydraulic control for a folding tool bar which has a transport width less than half the field working width.  Restric-tors are added in series in the right-hand folding lines to cause the left-hand outrigger to fold to the transport position first.          A one-way plunger operated ball check valve located in the hinge area between the main frame and an outrigger frame bypasses the restrictors for the first five degrees of fold and for the com-plete unfold cycle.  The outriggers can therefore be lifted together at the start of the fold cycle during turns in the headlands.  For complete folding to the transport position the left-hand outrigger folds first with the end of the right-hand outrigger positioned above it.  The ball check valve causes the right-hand outrigger to unfold out of the path of the left-hand outrigger during the unfolding cycle.

Abstract: ABSTRACT          The invention provides for diaphragm coated electrodes and processes for producing these diaphragm coated electrodes, as well as application of the diaphragm coated electrodes in electrolytic cells used in the electrolysis of brine to produce chlorine and caustic.  Specifically is disclosed a process whereby a slurry of asbestos fibers and polytetrafluoro-ethylene fibrids are deposited on a foraminous electrically conductive substrate to form a mat for a diaphragm.  The deposited slurry is heated to dry the mat and then there is a subsequent heating which may be around the transition temperature of polytetrafluoroethylene (327°C), and up to a temperature no more than 400°C in order to avoid degradation of the polytetrafluoroethylene.  The polytetrafluoroethylene fibrids are produced by shearing action on fibrillatable polymer, as opposed to the die-drawn polymer of the prior art.  The cost of the die-drawn polytetrafluoroethylene fibers of relatively large diameter is excessive and exceeds the cost of fibrids as described in the instant invention.

A flange extends radially from the container neck and a frangible annular groove is circumferentially disposed within the flange. A shoulder on the screw-cap is designed to press against the flange when the screw-cap is rotated downwardly on the neck.  The force of the shoulder pressing against the flange ruptures the frangible annular groove, there-by severing the end portion of the container neck from the remainder of the neck, and retaining it within the screw-cap.  A stop mechanism positioned in the threading of the container neck allows the screw-cap to be rotated downward to a point short of that necessary to rupture ;  the frangible annular groove and yet far enough to se-curely attach the cap to the container.  The stop mecha-nism also indicates when a container has been opened.
