Abstract: ABSTRACT OF THE DISCLOSURE           An improvement in NMR imaging techniques is disclosed, whereby the image is "shadowed" to intensify and contrast the image generated by the NMR sensitive nuclei, as a consequence of the introduction to the examined locus, e.g., human tissue of ferromagnetic, diamagnetic or paramagnetic particles.  The intensified and clarified image is itself diagnostically valuable, in accordance with art recognized methods but also provides an improved information base for establishing and controlling treatment modes, especially in determining spatial density and distribution of particles by comparing standard and entranced images.          According to a preferred embodiment, metabolizable particles are employed, whereby the change and rate of change with metabolic time can be imaged, compared, and correlated with various metabolic diseases or malignant states.

Abstract: (57)  Abstract of the Disclosure The invention is concerned with a winch device which comprises a working rope to be wound in onto a reel of its own for pulling or lifting a load as well as a control rope, likewise to be wound in onto a reel of its own, for controlling the operation of the winch.  The invention is in particular concerned with a method for controlling the operation of the winch so that the working rope and the control rope are wound in, and can be wound out, respectively, in the same direction and at the same speed.  According to the invention, this is accomplished so that a tendency is produced in the control rope to be pulled in, that the winding-in of the working-rope reel is caused by allowing the control rope to be pulled in over a certain advance distance relative the working rope, and that the speed of winding-in of the working rope is restricted, or the winding-in of the working rope is stopped, respectively, by restricting the winding-in of the control rope relative the winding-in of the working rope.  In a winch device for carrying out the invention, the operation has been accomplished by means of friction couplings (15,29) that receive drive power as well as by means of rotational wedge members (4,32) controlling their connecting and disconnecting, res-pectively, the axial state of expansion of the said rotational wedge members being adjusted by means of the said relative ratio of movement of the control rope (45) and the working rope (48).

Abstract: Abstract of the Disclosure A downhole tool includes a pipe string portion which is dis-posed in a pipe string of a well and a probe portion which can be lowered by wireline or other suitable means into the well for engagement with the pipe string portion.  The pipe string portion includes a sliding sleeve valve which is biased in a closed, or unactuated position, by a spring contained within the pipe string portion.  The probe portion includes a connector mechanism which engages lugs of the pipe string portion for imparting an opposing force to the sliding sleeve valve which overcomes the biasing force of the spring so that the valve can be opened to permit reservoir pressure to enter a cavity of the probe portion con-taining a sensor mechanism.  The coupling and decoupling of the connector mechanism with the lugs is effected through two down-ward and two upward movements of the probe portion.  The probe portion also includes a jarring mechanism for applying either an upward or a downward force impulse to the probe portion to faci-litate its movement should it become stuck, for example.

Abstract: DEWATERING OF MINERAL SLURRIES                              ABSTRACT           Mineral slurries are effectively dewatered by a process employing an aminofunctional silicon emulsion as a dewateriny aid.  The process provides for mixing the dewatering aid with the aqueous mineral slurry and there-after separating the treated slurry into a mineral portion and an aqueous portion.  The use of the aminofunctional silicones provide for reduced moisture content and/or increased production rate in a mineral slurry dewatering process.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus that serves to collect and account for empty beverage bottles in beverage stores.         A carriage is provided as the receptacle, the bottom of which is automatically displaceable in height by means of a chain drive, operated via light beam emitters and tripping vanes, in accordance with the bottles contin-ually introduced into the receptacle. The bottles, on being introduced, enter an intake rotor having sectors.          This rotor alternately changes its direction of rotation after each bottle is introduced, so that the bottles pass into the receptacle in two different directions in alternation via guide chutes.  Pyramids of bottles are thereby prevented from forming on one side only.  There-fore bottle breakage is avoided as a result of the adaptation of the height of the bottom, and that replac-ing a full container with an empty one can be accom-plished without difficulty.  When used with a bottle recognition and evaluation unit, the apparatus can accept bottles and calculate the amount of deposit due.

Abstract: ENERGY ECONOMIZER CONTROLLED-CURRENT START     AND PROTECTION FOR INDUCTION MOTORS                 ABSTRACT OF THE DISCLOSURE      A standard, unmodified induction motor starts with reduced input current, energy consumption and mechanical stress and is further protected from AC power source "phase loss", excessively low or high voltage or a locked-rotor condition during start-up or any subsequent moment while running when its stator winding is energized from a sine wave source through a signal-responsive wave modifier operative to control the portion of each cycle of the sine wave which is copuled from said source to the stator winding.  A stator current sampling arrangement, and a motor current demodulator responsive to the first few hundred microseconds of stator winding initial inrush current each time said current increases from zero cooperate under certain conditions to produce signals for controlling associated wave modifier means, thereby to achieve a preferred magnitude of motor starting current under rated load conditions and achieve near-optimum motor operating efficiency during start-up and subsequent running with reduced loads and associated motor protection means which inhibits said wave modifier means thereby to de-energize said stator winding under locked-rotor conditions that occur when motor start-up is attempted or later when the motor is running, or an AC power source anomaly occurs which would otherwise cause start-up stalling, excessive motor running current or motor stalling under rated loads.

Abstract: Abstract Supplemental ventilation apparatus is provided for manufactured housing whose window and door openings are tightly sealed when closed.  Exterior air is drawn in by the furnace's room air circulating blower through a flexible duct flattened wideningly at its base to fit removably on the upstanding flange of a dampered inlet to the furnace's upper air inlet chamber, which is installed in the narrow top wall surface of the furnace forward of its accessory-mounting portion. When combined with an adequately powered attic exhaust system, negative pressure, which such exhaust system creates in the attic, acts through openings in the ceiling to draw off positive room air pressure.  Thus stale room air is withdrawn and exhausted through the attic, without any increase in capacity of the room air circulating blower.

Abstract: ABSTRACT OF THE DISCLOSURE    The method according to the present invention enlarges a binary digital image by a method comprising the steps of: storing the rows of the image as a plurality of run end representations, in which a row is represented as a sequence of values giving the white and black run ends; enlarging each row of the image along the horizontal axis by altering the value of each run end representation to achieve enlargement on the horizontal axis by a factor F1; enlarging the image along the vertical axis by interpolating rows between the lines of the partially enlarged image so as to produce enlargement along the vertical axis by a factor F2; storing the enlarged size image generated by the above steps in run end form.  An image enlarged by the method of the present invention may be reduced by the simple technique of dividing the image into blocks of pixels and assigning one pixel in a reduced image for each block of pixels in the larger image.          Each pixel in the reduced image may by set equal to a center pixel in each block.
