Abstract: The method according to the invention for the decorative machining of glass, ceramics and products thereof is carried out by means of periodic pulsed transverse discharge under atmospheric pressure (RP TEA) of a CO2 laser at a pulse energy from 1 to 5 J, a power density from 1 x 10<6> to 6 x 10<7> W/cm<2>, a pulse duration from 50 to 100 ns, a pulse repetition frequency from 1 to 500 Hz and an average power from 1 to 1,000 W with a metal mask carrying a lithographically reproducible image by means of a supporting grid structure. The movement of the product to be decorated and the emission frequency of the laser are combined in such a way that 5 to 80% of the spots coincide, depending on the required contrast of the image. 
<??>The device for laser decoration consists of a base (1) with a console (2) which is mounted thereon and on which parallel elements (3) and a screw (4) are fixed. A nut (8) movable on the screw (4) is fixed by means of a second console (9) to a fork (10), on which a carriage (15) with longitudinal channels (16) is fastened by means of a handle (13) and a fixing device (14). The complete device is mounted in a sound-insulating box. A spherical mirror (34) which reflects the laser beam on to the mask (21) and focuses it is located in a seat (33).

Abstract: For dephosphorising molten metals having an iron content of at least 50 per cent by weight and contents of nickel, cobalt and copper of at most 30 per cent by weight in total, a particulate mixture of at least one alkali metal and/or alkaline earth metal and of at least one halide of the same alkali metal or alkaline earth metal is blown into the melt by means of an inert gas. The mixing ratio is here selected such that, under the reaction conditions, a minimum of the alkali metal or alkaline earth metal vapourises. The unconverted components of the mixture (alkali metal and alkaline earth metal and the halide or halides of these metals) and the phosphides, formed by the reaction, of the alkali metals and alkaline earth metals are collected in a top slag located above the melt, further reactions between the alkali metals and alkaline earth metals and the iron-containing molten metal being effected by the bath movement. Finally, the slag with the reaction products is separated from the molten metal, kept with exclusion of moisture and treated with oxygen or oxygen-containing compounds until the reaction products have been completely converted into oxygenated phosphorus compounds. <IMAGE>

Abstract: A satellite tracking antenna system comprises three or four plane antennas juxtaposed on a single plane. A first and a second antenna are juxtaposed in an azimuth direction, and a phase difference between signals received by these antennas is detected in order to determine a declination of an antenna unit with respect to the satellite as viewed in the azimuth direction. The first and a third antenna are juxtaposed in an elevation direction, and a phase difference between signals received by these antennas is detected to determine a declination of the antenna unit with respect to the satellite as viewed in the elevation direction. The antenna unit is driven so as to reduce these declinations to zero. Stated differently, values of a sine and a cosine function are extracted which have a phase difference between signals received by a pair of antennas as a parameter, and a tangent value representing the ratio therebetween is calculated and is then inversely converted to provide phase difference information.

The leading edge (47) of the connector insert is beveled. A corresponding beveled surface (42) is formed on the inner wall of the receptacle to engage and seal with the beveled leading edge of the connector to form a continuous, peripheral seal immediately adjacent to the wall of the tank so that when the vacuum motor is turned on, a positive force is generated to increase the effectiveness of the seal.

Abstract: A resilient pad (10) has a uniform patterned support surface, including a plurality of parallel ribs (18). Each rib (18) has a like profile of stacked compressible steps (23, 25, 27, 29) of varying widths. Progressive collapse of the steps (23, 25, 27, 29) under different loading results in differential resilient support responsive to such loading. Troughs (20) between adjacent ribs (18) have profiles identical to that of the ribs (18) when inverted so that two pads (10) may be simultaneously manufactured in mutually-facing, complementary alignment. The ribs (18) may execute a rocking action when loaded, which reduces the transmission of shear forces to a load such as a hospital patient, while rib compression provides an air pumping action for circulating air about the patient.

Abstract: The invention relates to an apparatus for atomising a liquid-metal casting stream by means of a gas emerging under pressure from a plurality of nozzles, the nozzles being arranged in the lower half of a pipe surrounding the casting stream and the nozzle axes intersecting the axis of the casting stream at spaced points of intersection lying one below the other, and the atomised metal forming a body on a moving base. In order to influence the quantitative distribution of the particles of the atomised metal in the spray stream over the cross-section in such a way that the profile of the spray stream leads to a more uniform thickness of the body produced, over its width, and that losses of the sprayed metal in the edge region are reduced, it is proposed according to the invention that the nozzles (12) be gathered into groups (14, 16) in such a way that, where they are at different distances from the axis of the casting stream, the groups have an identical angle of inclination or, where the distance is the same, the angle of inclination within a group is the same but adjacent groups have different angles of inclination, groups with nozzles at the same distance and the same angle of inclination being arranged opposite one another. <IMAGE>
