Abstract: Abstract of the Disclosure:  The fusible element of a single-element, dual-function,  electric fuse  is disposed within  a  passage  within a  housing  of  inorganic  ceramic material which has a high thermal conductivity; and the major portion of that fusible element is displaced radially from the axis of that passage to be  in  intimate  heat-transferring relation with one side of that passage.   Two of the "weak spots" of that fusible element are in close heat-transferring relation with the terminals of  that electric fuse;  and a portion of that fusible element which is intermediate those two weak spots is in intimate heat-transferring relation with the opposite side of that passage.  The resulting transference of heat from that fusible element to that passage enables those two weak spots to continuously carry the rated current of that fusible element even though those two weak spots have very small cross sections,  and hence are able to provide desirable current-interrupting action.

Abstract: SELECTIVELY PLUGGING WATER ZONES  ABSTRACT         A method for shutting off or decreasing the production of water from an oil well.  An oil well producing excess water is taken off production and a gas is injected into the well, followed by a slug of clean oil containing an emulsifier.  The well is then produced as fast as possible.  The previously injected gas and water in water-producing zones begin to finger back through the oil slug and forms a viscous emulsion which blocks the further flow of water into the producing well.

Abstract: ABSTRACT OF THE DISCLOSURE In the representative embodiment of the new and improved apparatus disclosed herein, a so-called "stuck-point indicator" or "freepoint-indicator" tool includes a deformation-responsive sensor tandemly supported between upper and lower hydraulically-operated tool anchors cooperatively arranged to be sequentially engaged with longitudinally-spaced wall portions of a string of well pipe believed to be stuck in a well bore. In the preferred embodiment of the tool, each tool anchor respectively includes a piston actuator which, upon application of a predetermined pressure as developed by a hydraulic-control system on the tool, operates to retract a set of movable anchoring elements and, upon a reduction in that hydraulic pressure, is biased by a spring to extend the anchoring elements.  To assure sequential operation of the upper and lower anchors, the hydraulic-control system of the tool further includes a flow restrictor for cooperatively delaying the reduction of the hydraulic pressure acting to retain the lower anchoring elements in their retracted positions until such time that the upper elements are moved into anchoring engagement with the pipe wall.

Abstract: ABSTRACT OF THE DISCLOSURE     A system is provided for automatically controlling the forward speed of travel of a combine in response to feeder and separator loading and to reduce speed in proportion to grain losses exceeding predetermined limits.   A hydrostatic transmission between the combine engine and drive wheels is controlled by a control element actuated by a hydraulic cylinder which is controlled from a control valve actuated by solenoids connected to the output of a comparator circuit.   Signals from separator and feeder load sensors and also from grain loss monitors are combined and applied to one input of the comparator circuit and a signal from a feedback sensor coupled to the hydraulic cylinder is applied to the second input of the comparator. The load sensors include potentiometers coupled to spring-loaded idler pulleys which are engaged with drive belts for the separator and feeder drive shafts and the feedback sensor is also a potentiometer.   Switching means are connected in circuit with the load sensing potentiometers for obtaining optimum levels and sensitivies and the proper propositions or the separator and feeder load signals, according to machine load conditions.  A manual control operates in conjunction with the transmission control element to limit maximum forward speed and to permit override of the  automatic control.

Abstract: ABSTRACT OF DISCLOSURE The invention provides a method and apparatus for manufacturing rounded containers having inner and outer mating wall parts of plastics with a printed paper segment between said parts. The method comprises locating an outer wall part at a paper insert station in alignment with the smaller open end of a tubular tapered guide, feeding a printed paper segment through the tapered guide,where it is progressively shaped to correspond with the container but is given slightly smaller dimensions,and into said outer wall part, whereupon the resilience of the segment due to bending causes it to expand into contact with the interior of said outer wall part. An inner wall part is pressed into the outer wall at a subsequent operating station. The apparatus is arranged specifically to effect the above method.
