Abstract: 1400860 Removing material by laser beams; making waveguides WESTERN ELECTRIC CO Inc 25 Oct 1972 [26 Oct 1971] 49185/72 Headings B3V and B3A [Also in Divisions C7 and H1] A portion of an electrically conductive surface 12 overlying a dielectric surface on the inner wall of a hollow member 11 is modified or removed by irradiating it in the presence of a wet oxygen plasma. In one embodiment, a laser beam 22 from a source 21 is passed through an end plate 14, sealing the end of a steel waveguide tube 11, and reflected by a prism or mirror 23 through a focusing lens 24 onto the tubes inner surface 12 which comprises a copper coating covering a layer of silicon dioxide dielectric. The reflector 23 is mounted on a piston 13 which is simultaneously translated and rotated so that the laser beam 22 traces a helical path. The interior of the tube 11 is fitted through a line 18 with an atmosphere produced by bubbling oxygen through boiling water. A wet oxygen plasma is generated by the focused laser beam 22 causing the copper coating on the tube's inner surface 12 to be oxidized thereby facilitating its removal by the laser beam 22. A high voltage discharge may also be produced between the point of laser impingement and an electrode on the piston 13 to generate an oxygen plasma. The vapours produced are exhausted through a line 19, which is connected to a vacuum pump. A pattern of spaced rings may alternatively be formed on the tube's inner surface. Portions of the workpiece may alternatively be oxidized by the laser beam instead of vaporized.

Abstract: 1,175,756. Producing crimped polypropylene filaments. TOYO BOSEKI K.K. 30 Oct., 1967 [1 Nov., 1966], No. 49276/67. Heading B5B. Crimped polypropylene filaments or staple fibres are produced by melt-spinning an isotactic polypropylene or a polymer composed mostly of an isotactic polypropylene through a spinneret and winding up the filaments formed in which the minimum distance between the orifices is more than 4À0 mm., preferably more than 6À0 mm., blowing a stream of cooling gas at a velocity of more than 0À3 m./sec., e.g. 0À45 to 1À2 m./sec. across the extruded filaments, the distance D in cm. between the spinneret face and the uppermost portion of the gas stream being such as to satisfy the formula wherein V is the rate in m./min. at which the drawn down filaments are wound up and d is a single filament denier of the drawn-down filaments, to produce drawn-down filaments in which the corrected density pp (g./cm.<SP>3</SP>) is in the range represented by the formula 1À67 x 10<SP>-6</SP>d<SP>2</SP>-3À4 Î 10<SP>-6</SP>d + 0À9040## p #1À67 x 10<SP>-6</SP> d<SP>2</SP>-3À4 x 10<SP>-6</SP>d + 0À9058, in which the degree of asymmetry (As) of mean birefringence is more than 5% and in which the intrinsic viscosity is 1À05 to 1À50. The filaments thus obtained are stretched at a draw ratio of 2À5 or higher at such a stretching temperature that the temperature T (‹C.) of the filaments being stretched is in the range normal atmospheric temperature #T#120-d so that fine voids are distributed asymmetrically in the cross-sections of the filaments. The filaments are then heat-treated in the relaxed state at a temperature of 80‹ to 150‹ C., whereby they spontaneously develop crimps or the filaments are cut up to form staple fibres and the staple fibres are heat-treated at a temperature of 80‹ to 150‹ C. whereby they are crimped. The temperature of the cooling gas may be 0‹ to 25‹ C. Its velocity may be 0À45 to 1À2 m./sec. The drawn-down filaments may be preheat-treated at a temperature of from 25‹ to 140‹ C. for a time sufficient to promote the desired degree of asymmetry. The preferred heat treating temperature preceding the stretching step is within the range 70‹ to 135‹ C. The drawn-down filaments may have a crimp potential such that when they are stretched and heat-treated they will have a helix diameter of less than 0À7 mm. The expression " corrected density " #p (g./cm.<SP>3</SP>) is a density corrected to eliminate the influence of any polymer or additive which may be present in the filaments in the density of the undrawn filament, the correction being made according to the formula wherein p is the density of the undrawn filament, # a  is the density of the other polymer or additive and Vp is the percentage by volume of the polypropylene.
