Patent EP-0226434-A2 (EP)
Inventor: LO YING-CHENG
IPC: B29C48/08
Filed: 1986-12-09
Abstract: Biaxially oriented polymer sheet (70) is produced by advancing a workpiece (67) of polymer material in the longitudinal direction between opposed working surfaces (56, 57, 61, 62), causing the material of the workpiece to flow simultaneously in the longitudinal direction (Z) and the sideways direction (Y) whilst decreasing the thickness of the workpiece in the direction (X) by squeezing the workpiece between the opposed working surfaces. The friction between the polymer material and the working surfaces is compensated for by squeezing the workpiece more at the centre than at the edges thereof in the widthwise direction (Y) whereby the material of the workpiece flows bidirectionally to produce the biaxially oriented sheet. In one embodiment, the workpiece is forced through a die affording two opposed surfaces (56, 57) which converge in the longitudinal direction and which carry respective projections (61, 62) which are convex across the width of the workpiece. In an alternative embodiment, the workpiece is drawn between a pair of opposed flexible belts (80, 81) supported by pairs of opposed rollers (87A-N), the spacing of the pairs of rollers and the convexity of the rollers decreasing in the longitudinal direction (Z).

Abstract: Ultrapure silicon nitride precursor is made by: (a) continuously reacting liquid silicon halide (SiCl 4 ) with an excess of liquid ammonia (NH 3 ) (i) in the effective absence of contaminants, (ii) at a reaction situs in an inert atmosphere to form the silicon nitride precursor as a precipitate, and (iii) with a ratio of liquid ammonia to silicon halide (equal to or greater than 21 molar) effective to solubilize any gas reaction products; (b) providing a pressure differential to simultaneously and continuously withdraw a filtered portion of the excess liquid ammonia to leave the silicon nitride precursor precipitate in the reaction situs; and (c) adding ammonia to the excess of ammonia in said reaction situs to replace the withdrawn filtered portion of the liquid ammonia. 
     The reaction is carried out with vigorous stirring of the liquid mixture and the atmosphere over the entire mixture is regulated to contain only ammonia vapor and nitrogen. The temperature of the liquid mixture is maintained between -33°C to -69°C by employing a cooling jacket containing dry ice, a slush of dry ice and acetone, isopropanol or cellosolve, and by recycling the withdrawn liquid ammonia and re-adding it to the reaction situs either as a cooling liquid or as a heating gas.

IPC: B23K9/28
Filed: 1986-02-12
Abstract: A contact tip for supporting a consumable welding electrode and for supplying welding current thereto. The contact tip is generally rod-shaped and has a passage with a helical contact surface. The welding electrode is fed through the passage and makes electrical contact with the contact tip. Because of the helical contact surface, the passage never becomes constricted by cumulative deposits of dirt and extraneous matter from the welding electrode surface. Also, the helical contact surface, which axially extends at least one complete turn, has an unbending effect on the welding electrode, thus straightening the electrode. A distance "A" of the electrode axis from the contact tip axis may be chosen, as desired, considering the diameter of the welding electrode. Optionally, the contact tip may include a sleeve-like nozzle, to shield the contact tip from deposits of welding splatter.

Abstract: An inflatable attenuator (40) having an inflatable resilient bladder (46) enclosed by a perforated protective cylindrical housing is positioned in a liquid column in a well (10) below (and if desired another inflatable attenuator is also positioned above) an impul­sive energy source (20) in the liquid column. The housing (42) has an exterior diameter slightly less than the interior diameter of the well (10). The bladder (46) is inflated when in the liquid column by gas supplied from a pressurized gas container attached to the attenu­ator or is supplied with pressurized gas through a hose line from a source of pressurized gas located on the surface of the Earth near the mouth of the well. A pressure-regulator respon­sive to the ambient hydrostatic pressure in the liquid column near the pressure regulator serves to maintain the pressure of the gas within the bladder at a regulated pressure at least equal to the ambient pressure in the liquid column where it is located. A pressure-relief valve (50) releases pressurized gas from the bladder to prevent the pressure inside of the bladder from exceeding a predetermined differential in pressure between the inside of the bladder and ambient hydrostatic pressure so that the bladder (46) will not rupture when the attenuator (40) is being elevated in the well. The inflated bladder (46) attenuates tube waves (32) traveling along the liquid column in the well (10) from an impulsive source (20) of seismic energy waves when employed in the liquid col­umn above or below the energy source. The upwardly traveling tube waves (35) may alternatively be dissipated by releasing numerous gas bubbles (72) in the upper portion of the liquid column to generate a bubble barrier in the upper portion of the liquid column. A further embodiment includes two bladders, including a tapered upper bladder which flares outwardly and downwardly and a cylindrical lower bladder. The perforated protective housing is omitted, and enlarged annular shoulders protect these bladders from abrasion against the wall of the well.
