Abstract: ABSTRACT OF THE DISCLOSURE      A closed loop hermetically sealed solar power generator and water purifying system are provided herein.  It includes a hollow globular boiler.  The globular boiler includes an upwardly directed steam outlet conduit originating from an upper half of the globular boiler, and a refractor lens win-dow disposed within an upper half of the globular boiler.  The glubular boiler is adapted to contain a body of water.  Means, e.g. a controllable paraboloid mirror, are provided for dir-ecting the sun's rays towards the refractor lens window to generate heat to boil water from the body of water in the glob-ular boiler.  A primary turbine is disposed at a level above that of the boiler, the turbine being connected to the steam outlet conduit and being drivenby steam under pressure from the boiler. Steam condenser means  are connected to the ef-fluent from the primary turbine for dissipating residual heat in the steam effluent from the turbine and for condensing such steam as substantially pure water.  A reservoir is connected to the condenser means and is disposed at a level which is lower than that of the primary turbine, but at a level which is hi??er than that of the globular boiler, for receiving such substan-tially pure water.  It is also used for adding the original make-up water.  A secondary turbine is disposed at a level which is lower than that of the globular boiler.  The second-ary turbine is connected to the reservoir and is driven by water from the reservoir.  Pure water effluent means are pro-vided which lead from the secondary turbine to the globular boiler.  Such solar power generator is thus very energy effic-ient and ecologically conservative since the work liquid (i.e., the water) is returned to its original source when its work has been extracted.

Abstract: ABSTRACT OF THE INVENTION           An apparatus for precisely moving a camera lens element to focus an image at the camera's film plane is disclosed.  The apparatus employs an electrically controlled and incrementally stepped rotating motor which moves a lens element parallel to the lens axis.  The disclosed motor is an epicyclic motor, and a mechanical coupling arrangement interconnects a driven rotating motor element and the lens element holder and converts the rotary motion of the motor to incremental translation of the lens element.  The apparatus moves the lens element in this manner in small  precisely controlled increments, for example, steps of less than 0.001 inch.

Abstract: ABSTRACT OF THE DISCLOSURE          A wire matrix printer includes a print head having banks of print wires arranged for linear reciprocation toward and away from a recording surface by associated actuators.  Outer or actuator ends of the wires define a vertically spaced and stepped array with actuators also in an array vertically spaced and stepped and respectively coupled to the outer print wire ends by armatures. The inner or printing ends of the wires define a vertically spaced, nearly planar array near the recording surface, and a spaced, planar array at such surface.  The banks are angularly spaced from a line extending perpendicularly from the recording surface, and the inner ends of the wires in each bank are alternately interleaved near the recording surface.  The actuators in each bank also include torsion springs, pole pieces, a permanent magnet and an electrical coil about but not mechanically loading each armature.  The pole pieces are magnetized by the permanent magnet to normally attract and hold each armature adja-cent thereto against the action of its associated torsion spring, thereby storing potential energy therein.  The flux of the permanent magnet is momentarily neutralized for a selected arma-ture by energization of its associated coil to allow the armature too rotate on and about one of its pole pieces for impacting the inner end of the print wire couplet thereto against the recording surface due to conversion of the potential energy stored in the torsion spring to kinetic energy of the armature.

Abstract: ABSTRACT A method is disclosed of making refiner pulp by refining ligno-cellulose-containing material having a concentration of 8-15%, measured as discharge concentration.  The material is refined in a disc refiner during its passage out through the gap between the refining discs of the refiner to a surrounding refiner housing.  Water is continuously supplied to the housing outside the refining discs to dilute the refined material to a fibre suspension of a concentration which is easy to pump.  The housing is maintained filled with the suspension in order to reduce the pulp flow through the refiner, and thereby the retention time of the material between the refining discs.

Abstract: Abstract A programmable control latch mechanism which is particularly useful in a microprocessor.  One or more control latches are provided which can be set or reset under direct program control directly from the instruc-tion register of a data processor by the loading therein of a unique program instruction.  The unique instruction includes for each control latch two predetermined bit positions, one of which determines whether or not the control latch is to be changed and the other of which determines the binary value to which the control latch is to be changed.  This enables anywhere from one to all of the control latches to be changed by a single instruc-tion and enables each latch which is changed to be changed to any desired binary value.  The control latch outputs can be used for storage page selection, direct control of external devices or circuits, selection of internal processor functions and the like.

Abstract: ABSTRACT OF THE DISCLOSURE A rotor for an induction motor is made of a stack of punchings forming the body of the rotor and including a set of main punchings with integral spring punchings spaced apart in the stack of punchings.  The main punchings have conductor receiving slots which preferably are closed at the periphery and have a portion at the radially inward end which extends deeper than is necessary to accommodate a conductor. The integral spring punchings have conductor receiving slots which align with those of the main punchings, and they also have a portion at the radially inward end which extends deeper than necessary to accommodate the conductor.  The integral spring punchings have a projecting integral tab at the inner extent of the slot.  This spring tab is deflected when the conductor is installed and provides on the conductor an outwardly directed spring force to reduce vibration and rattling.
