Abstract: METALLIZED WOVEN FABRIC      ABSTRACT OF THE DISCLOSURE This invention relates to the field of fabrics woven at least partially from metal wire and including areas of double layer fabric. Tubular metal fabric is well-known in the art, but since the conventional fabric consists of a single tube formed of the entire double layer width of the fabric, the size of the tube is limited to the width of the fabric and cannot be reduced without destroying the tube.  It is often necessary to produce irregular shaped double layer fabric for use in filters and the like.  This cannot be done easily with the single tubular fabric of the prior art.  The present invention overcomes these defects by providing an improved woven fabric including metal wire in at least one of the warp and weft directions.  The fabric includes alternating areas of double and single weaving forming alternating areas of double layer or combined single layer fabric.  These areas alternate in at least one of the warp and weft directions.

Abstract: ABSTRACT      A method and an apparatus for improving the speed of executing instructions and reducing the microprogram memory requirements in a conventional digital computer system by eliminating a ROM address register for addressing micro-words.  The method or apparatus incorporates the use of a predetermined bit position in the microinstruction word which is set to a binary one when the microword is the last microword of an executing microprogram.  The apparatus is responsive to the electronic representation of the binary one signal to cause the microinstruction execution sequence to branch to a predetermined location in the microprogram memory for execution of the following microinstruction; thus eliminating one ROM address register and at least one step in returning to a common address for starting the execution of another microprogram.

Abstract: HAMMER     ABSTRACT     A fluid operable hammer has a hammer piston reciprocably slidable in an elongated bore of a body member so as to provide work and return strokes.  The piston defines a variable volume chamber in the bore which chamber is supplied with hydraulic fluid to effect the return strokes.  A valve is selectively movable to a first position to permit the supply of hydraulic fluid to the variable volume chamber, and to a second position whereby an exhaust chamber can receive hydraulic fluid from the variable volume chamber.  With the valve in the second position a work stroke may be accomplished, while a return stroke is effected with the valve in the first position.  The valve is constructed so that hydraulic fluid is discharged from the exhaust chamber as the valve moves from the second position to the first position.          The hammer is simplified in construction and may, contrary to prior art devices be operated in any and all orient-ations.  Furthermore hydraulic fluid back pressure, which limits piston movement, is minimized.
