Abstract: Abstract of the Disclosure A housing which is connectible to a pressure sensitive tool has a filter cartridge mounted within it to communicate a pressure from an external fluid to a clean fluid contained within the filter cartridge and the tool.  The filter car-tridge includes one or more filters having a plurality of passageways small enough to hold the clean fluid under pres-sure equilibrium conditions, but large enough to communicate pressure from the external fluid to the clean fluid.  There are enough of such passageways so that it is unlikely that all will become clogged by any contaminants within the external fluid should a portion of the external fluid be sucked in through the filter in response to expansion and contraction phenomena of the clean fluid.

Abstract: Apparatus for the electrical discharge machining of a circumferential section from the wall of a bore in a metallic cylinder has a housing and a wire electrode guide disposed within the housing.  A wire feeder continuously feeds a wire electrode to the wire electrode guide.  The wire electrode guide also moves the wire electrode radially into and out of an axial groove extending between the circumferential grooves in the bore wall.  The wire electrode guide further moves a wire electrode, when the wire electrode is disposed within the axial groove in the bore wall, between a first position in which the distance along the bore wall between the point where the wire electrode enters and leaves the axial groove is the same as the distance between the circumferential grooves, and a second position in which the distance along the wall of the bore between the point where the wire electrode enters and leaves the axial groove is greater than the distance between the  circumferential  grooves.    A  rectifier  and  current controller provide an electrical discharge through the wire electrode.  A motor resolver rotates the wire electrode guide circumferentially within the bore.

Abstract: Abstract Laser jet welding of an outer sleeve to an inner fiber ferrule is expedited by, first, machining a thinned region in the outer diameter of the sleeve. After the ferrule has been inserted in the sleeve, the thinned region permits the laser to fuse through the sleeve and melt part of the ferrule, as is required for laser welding of ferrule for the sleeve. The thinned region is preferably made by using a rotary cutter to cut an axially extending slot in the outer sleeve, which permits a succession of laser welds in the axial direction in the slot. In a preferred embodiment, thinned regions are made on opposite sides of the outer sleeve, and laser welding is performed simultaneously on both sides of the sleeve so as to avoid distortions caused by thermal stress asymmetries.
