Abstract: An improved method of solution well mining is provided which, among other advantages, enhances the injectivity of the wells and eliminates the need for underreaming and the use of well screens.  In solution well mining, a leaching solution is pumped into an injection well so as to flow through a mineralize zone to a plurality of production wells, the solution which contains the mineral to be recovered being pumped out of the production wells.  The invention provides for using a high pressure water jet to perforate the cemented casings of the well so as to, inter alia, enhance injectivity and provide sand control.  The perforations are arranged in a preselected non-uniform pattern in the production well, with the density being the greatest at the bottom of the zone, so as to promote uniform flow of the solution.

Abstract: ABSTRACT     A planetary gearing module has an input shaft, an output shaft and a first and a second planet carrier.  Planet gear wheels and planet friction wheels are supported on planet wheel shafts between the carriers.  The gear wheels engage a gear ring encircling them and a sun gear wheel.  The friction wheels cooperate with a friction ring encircling them and with a friction sun wheel.  These parts together form a gearing step and each step forms an intagral unit.  The carriers are fastened together by means of the wheel shafts to form a cage structure.  Several gearing modules formed by the units can be interconnected in a common housing.  The input shaft of one of the modules is connectable to the output shaft of an adjacent module.  The gear ring or the friction ring can be firmly fixed in the housing and the non-fixed ring is radially movable.

Abstract: ABSTRACT OF THE DISCLOSURE      This operating system comprises a fluid motor having a piston, a breaker-opening space at one side of the piston, and breaker-closing space at its opposite side. An accumulator freely communicates with the breaker-opening space for supplying pressurized fluid thereto during a circuit-breaker opening operation.  A normally-closed valve located on the breaker-closing-side of the piston is openable to release liquid from the breaker-closing space so that pressurized liquid in the breaker-opening space can drive the piston in an opening direction. Means is provided for restoring the valve to its closed position following the circuit-breaker opening operation. An impeded passage affords communication between the accumulator and the breaker-closing space to allow pressurized liquid to flow from the accumulator to the breaker-closing space and develop a pressure therein substantially equal to accumulator pressure when the calve is restored to closed position following break-opening.  This passage is so impeded that the flow therethrough from the accumulator into the breaker-closing space is sufficiently low during initial open-ing motion of the piston through a substantial portion of its opening stroke as to avoid interference with said initial opening motion of the piston.

Abstract: ABSTRACT OF THE DISCLOSURE      An extruder having a multichannel  wave screw is dis-closed wherein at  least one  portion of the screw is provided with a helical passage that is divided into a pair of parallel flow channels. The helical passage is defined by a helical conveying land which extends radially outwardly to a first diameter from the screw root, which defines the bottom  surface of the helical passage. To divide the helical passage into the pair of flow channels, a helical barrier land extends radially outwardly to a second diameter which is less than the first diameter. Each flow channel is further characterized by the existence of an undulating screw root which defines a plurality of waves, each with a crest and a valley. The crest of one flow channel are helically displaced relative to the crests of the adjacent flow channel. In addition, the difference between the second diameter and the first diameter is selected such that plasticated synthetic resinous material may flow from one flow channel into the other flow channel while unplasticated particles are subjected to intensive shearing forces by the crests of the respective flow channels. The wave cycle of each flow channel, defined as the distance between successive crests, is relatively short, eg. less than about 360° along each channel (i.e., less than about one full screw turn). Preferably, the wave crests are positioned 180° apart along the channel.

The  system includes a linearly arranged array of side-by-side transducers  adapted for propagating ultra-sonic energy into a body co be ultrasonically examined and for receiving reradiated sonic energy from points within the body.  A signal channel is connected to each of the transducers for activating same to propagate the sonic energy and for receiving electrical signals from the transducers (which correspond to the reradiated energy).  Controllable delay means are provided in each of the channels for introducing linear phase shifts in the electrical signals proceeding in the channels during both transmission and reception to thereby azimuthally steer the transducer array.  Means are further provided for processing the received signals proceeding through the channels and for combining same to effect a visual display of the bodily portion being examined.  Means synchronized with the activating of the transmitters periodically reduce the gain of one or more symmetric outer transducer pairs of the array, thereby effecting reducing the aperture of the array to enable improved response to reflected acoustic information reaching 2nerSJK012979 the array from the near field thereof.  The outer elements are similarly restored to enlarge the effective array aper-ture for improved response to reflected acoustic information arising from the far field of the array.
