Abstract: ABSTRACT OF THE DISCLOSURE An efficient, portable, easy to operate fastener applying tool is disclosed that is powered by the gases produced from the internal combustion of a fuel and air mixture.  A supply of liquified gas stored under pressure in a cylinder provides the source of power.  A piston connected to a fastener driver is slidably mounted within a cylinder to move reciprocally downwardly and upwardly through a driving and a return stroke.  A combustion chamber is formed at the upper end of the cylinder.  A compression chamber is formed at the lower end of the cylinder.  A spark plug powered by a piezo-electric firing device, is located within the combustion chamber.  The combustion chamber features a set of fan blades driven by an electric motor which is continuously in operation when the tool is in use.  A main valve mechanism actuated by a set of lifting rods which are moved upwardly and downwardly when the tool is moved toward and away from the workpiece, is used to control the flow of fresh air through the combustion chamber.  When the combustion chamber is isolated from the atmosphere and the fuel and air are thoroughly mixed, the spark plug is fired to explode the fuel and air mixture and force the piston through its driving stroke.  Air compressed by the lower end of the piston at the lower end of the cylinder is used to form an air bumper to keep the piston from striking the bottom of the cylinder.  An exhaust valve is mounted at the side of the cylinder to discharge combustion gases at the end of the driving stroke.  The rapid discharge of combustion gases at the end of the driving stroke produces a thermal vacuum within the combustion chamber.  Additional air supplied to the lower face of the piston from the atmosphere forces the piston through its return stroke.  A simple but reliable interlock mechanism is used to insure the safe operation and sequencing of the various components of the tool.  The unique use of the electric fan improves the overall operation of the tool and the utilization of the liquified combustible gas.  It also insures that the piston is forced through its return stroke by atmospheric pressure alone.

Abstract: ABSTRACT Disclosed is a method which makes it possible to address specific text units very quickly.  This is achieved by providing a table allocated to the highest hierarchy stage, for storing the index of the first text unit of the second highest hierarchy stage.  Further tables are provided, associated with the lower hierarchy stages, each for storing the indices of the text units of the next lower hierarchy stages.  The tables are refer-red to successively, in decreasing order of hierarchy, until the index of the text unit which is being sought is reached.  Very fast access can be had to specific text units.  The physical address of each text unit is stored under the corresponding index in the table which is allocated to the lowest hierarchy stage.  Text units can be inserted and deleted very quickly in a simple manner, since only the indices need to be changed in the tables. When text units are removed, the entire concatenation of text units is not formed anew, but rather the indices of the previous and following text units are changed.  When text units are inserted, the indices applying to the text units before and after point of insertion are changed.

Abstract: Abstract Molten metal such as the light metals aluminum and magnesium containing finely divided suspended particles is treated to remove such particles and beneficiate the metal.  The particles are typically in the micron size range and may include solid material such as oxides or solid salt particles and may include buoyant liquid particles such as liquid salt particles. Solid particles may be attached to or encapsulated within liquid salt particles.  The molten metal containing the suspended particles is moved through a medium of submerged contacting surfaces such as a packed bed.  The contacting medium has a high void fraction and a high specific surface area.  This results in coalescence or agglomeration of the particles which are thus rendered more responsive to gravity separation than the fine particles.  The molten metal preferably is then passed through inclined channels or passages in contact with inclined surfaces such as parallel plates or tubes, the movement therethrough being substantially laminar.  Buoyant particles and agglomerates collect on the underside of the inclined surfaces and typically move upwardly in counterflow relationship with metal where the metal moves laterally and downwardly through the inclined passages.  A plurality of such inclined surfaces may be provided as tubes or parallel plates. A gas such as a nonreactive gas with or without a chlorinaceous or halogenaceous gas may be bubbled through the contacting medium for further treatment of the molten metal.  Such gas can be used to provide a mild disturbance in the contacting medium to aid removal of agglomerated particles, especially buoyant particles, there-from.

Abstract: ABSTRACT         To repair worn-out bearing lugs, the worn bores are enlarged and are then built up by the application of helical layers of weld material.  The bores are then enlarged by metal removal to the desired diameter. This is a significant improvement over the prior art method wherein worn lugs were repaired by inserting a replacement sleeve and welding it in place.  Such sleeves to be weldable had to be made of relatively soft material and therefore were subject to rapid wear.  In contrast the welded fillets applied in the present invention produce a hard material with good wear resistance.
