Abstract: Abstract of the Disclosure A lift ring device for installation in the forward portion of the deck of a boat or other item that may need from time to time to be lifted, which device can be retracted when not in use, thus to leave the deck of the boat relatively uncluttered.  The lift ring (20, 60) is disposed in a slotted deck plate (12, 52) and out of this slot the lift ring may be readily lifted so that it can serve either as a deck cleat, or in the lifting or towing of the boat. A lower, rod-like portion (26, 66) is integral with the lift ring, and this rod-like portion is slidable in an elongate structural member (16, 56) attached to the under-side of the deck plate.  We use a compression spring (28, 68) around the rod-like portion in order to insure retraction of the lift ring when not in use, and a sturdy, weight bearing device is provided on the lowermost end of the rod-like portion to assure that the lift ring will not separate from the deck plate during the lifting of the boat.  The lower-most part of the elongate structural member is provided with a rotatable device (46, 86) to receive the upper, threaded end of a rod attached to the keel of the bolt, such that no turnbuckle is required in securing the lift ring device firmly to the keel.

Abstract: SYSTEM AND METHOD FOR FORMATTING PAIRS OF CONCENTRIC MAGNETIC TRACKS OF DIFFERENT CAPACITY TO A PLURALITY OF EQUAL CAPACITY LOGICAL TRACKS            Abstract of the Disclosure A method and system are disclosed for storing data on a magnetic disk file to increase the overall storage capacity of the file without complicating the data management functions and aspects of the connected data processing system.  The system involves a magnetic disk having concentric recording tracks where a first inner group of tracks are recorded at one frequency fl, providing optimum track capcity X for these tracks, and a second outer group of tracks are recorded at a second frequency f2, which also provides optimum track capacity for these tracks.  At each address position, a pair of magnetic transducers are associated with a different track from each group  During the writing or reading of serial by byte data, the pair of tracks are transduced on successive revolutions.  Suitable switching circuitry for switching from one transducer to the other in response to sensing "index" is provided and also for changing the clock frequency.  The system further includes  suitable  disk  formatting  circuitry  for converting the two physical tracks into one (or more) logical tracks having the same byte capacity.            The method is characterized by the steps of switching at index from one transducer to the other and adjusting the clock frequency accordingly so all logical records have the same capacity. The magnetic disk may be divided into more than two groups of tracks, if desired.

Abstract: IMPROVED AIR CLEANER HAVING A                 DUST DUMPING VALVE Abstract of the Disclosure An air cleaner for an internal combustion engine, having a dust dumping valve.  The air cleaner includes an outer housing contianing a filter element and air is introduced into the housing and swirled outwardly before passing through the filter element for discharge. The heavier dust particles in the air are moved under centrifugal force to the inner surface of the housing and are discharged through a conical outlet in the lower end of the housing to a dust trap.  The lower end of the trap is provided with a plurality of open-ings which are enclosed by a flexible rubber-like disc. When the engine is operating, the engine vacuum will draw the disc tightly against the openings to prevent the entrance of air into the trap.  The weight of the dust collected in the trap in combination with the engine vibration will intermittently cause the rubber disc to drop away from the openings to discharge a portion of the collected dust.  On stopping of the engine, the weight of the collected dust in the trap will open the disc valve to discharge the entire quantity of dust from the trap.

Abstract: APPARATUS AND METHOD FOR ENERGY PRODUCTION AND MINERAL RECOVERY FROM GEOTHERMAL AND GEOPRESSURED FLUIDS     ABSTRACT OF THE DISCLOSURE          Apparatus and method for using the vapor fraction f geothermal or geopressured fluid to produce useful work and for using the solid fraction of the fluid for producing minerals of commercial value while providing protection from scaling.  The fluid is directed into a first chamber in which the fluid flashes to generate the vapor fraction.  A circulatory flow through the first chamber occurs as a result of the flashing of the vapor fraction, causing the vapor fraction to separate from the solid and liquid frac-tions and allowing the vapor fraction to pass to a fluid-actuated, work-producing apparatus.  The solid and liquid fractions gravitate into a second chamber adjacent to the first chamber and extending below the first chamber.  The second chamber permits at least a portion of the liquid fraction to separate from the solid fraction by clarifica-tion.  Crystal growth continuously occurs in the first and second chambers as the circulation of the fluid continues through the first chamber.  When the crystals become large enough, they gravitate to the bottom of the second chamber and can be removed therefrom.  The crystals can be provided by self-nucleation or by the addition to the fluid of minerals, sand, glass or metal pebbles.  Crystals, after removal from the second chamber, can be recycled to provide nuclei for further crystallization.  The separated liquid fraction of the fluid can be directed to a point of disposal or through one or more additional reactor stages to recover the remaining energy and mineral values therefrom.  Spent fluid is directed through a filter and to the point of disposal, such as a reinjection  well.  In a first improve-ment of the system, a portion of the fluid in the second chamber is removed and heated by the flashed vapor fraction and then redirected into the top of the second chamber to increase the concentration of the mineral value-s thereof by increasing the vapor fraction of the fluid.  In another improvement, pure vapor is provided for the work producing apparatus by heating pure distillate from the condenser associated with the work  producing apparatus.  The heat is supplied by directing the vapor fraction of the fluid into heat exchange relationship with the distillate whereby the distillate boils and becomes pure vapor.          This invention relates to improvements in the handling of geothermal brines and geopressured fluids which have solid, liquid and vapor fractions and, more particu-larly, to an apparatus and method for recovering the energy, mineral and water values from such brines or fluids.

Abstract: ABSTRACT OF THE DISCLOSURE         The functional relationship between the torque delivered by the motor or a quantity characteristic of the torque and the register adjustment necessary for maintaining perfect register is recorded and stored in a memory 15 in order to prevent register errors in multi-colour rotary prin-ting presses, particularly in multi-colour offset printing presses, whose printing units are driven by a common motor and exhibit a register adjusting device.  While the press is running the torque delivered by the motor or the quantity characteristic thereof is monitored and the register adjust-ment is set to the value functionally assigned to the re-spective torque.  Since the functional relationship between torque and register adjustment is a characteristic of the respective printing press, the printer can bring the printed images exhibiting various colours into perfect register with the printing press running at low speed and can then run the press up to the desired printing rate without there being any register errors because such errors are prevented by the register adjustment which, as the speed of the press increases, is carried out as a function of the increasing torque in accordance with the previously determined functional relationship.

Abstract: ABSTRACT         This invention relates to a solar energy storage material comprising N,N'-bis(phenylacetyl)indigo dissolved in a polar solvent.  Of the indigo derivatives capable of storing the solar energy by the photoisomeriz-ation from trans-isomer to cis-isomer of the molecule, all of the compounds obtained so far had an energy storage capacity of only 30 cal or less per 1 g of the compound and also a high thermal isomerization rate from cis form to trans form in solution.  Thus, they cannot be called a solar energy storage material of practical value.         In the case of the present invention, on the other hand, when N,N'-bis(phenylacetyl)indigo is dis-solved in a polar solvent such as acetonitrile, it is possible to store about 60 cal of energy per 1 g of N,N'-bis(phenylacetyl)indigo, and the half-life period of isomerization from cis to trans from in acetonitrile at 17°C is 1,264 minutes, which is also a satisfactory value for practical application.

Abstract: ABSTRACT OF THE DISCLOSURE A gas-heated or kerosene-heated boiler for warm water, hot water or for steam generation has a substantially horizontal cylindrical combustion chamber defined and surrounded by a flue tube consisting of a plurality of annular ring tubes that are arranged in succession for conveying a suitable heat carrier and are held together by means of annular distance strips.  At least some of the annular ring tubes have different inner cross sections and/or are arranged in a manner of having different, unequal spacing distances one to the next.  Thus, a substantially uniform main diameter of the flue tube is maintained, and despite of this, the flow of heat carrier circulated is har-monized with the thermal load which is non-equally distributed along the axis of the combustion chamber, resulting in improved utilization of the heat energy radiation at substantially constant wall temperature along the flue tube.
