Abstract: A method and apparatus for generating high current, negative ion beams is described. A plasma source of ions of one charge polarity includes an accelerator for accelerating the ions toward a target having a plurality of apertures. An electric field directs the ions exiting the apertures against a target surface which is arranged to emit ions of an opposite polarity. The electric field directs the opposite polarity ions away from the target forming a stream of oppositely charged ions. 
<??>In the drawing the ions produced in the plasma chamber 10 are accelerated toward the apertured grid 12 by field 8 and pass through the aligned apertures in the grid 12 and target 16. A field established between apertured grid 18 and target 16 reverses the general direction of the ion beams so that they bombard the back surface of the target. Ions of the opposite polarity are emitted from the back of the target and are accelerated away from the target by the field between the grid 18 and the target. The opposite polarity ions exit as streams through the apertures in the grid 18.

Abstract: A method of marine seismic investigation involves positioning or deploying at a predetermined point close to or within a multi-element seismic source array a calibration source which is an acoustic pressure wave point source which has a far-field seismic signature of broad bandwidth. The radiated pressure wave field of the calibration source (3) is weaker than that of the main source (2). The two sources are fired at separate instants within a predetermined time range, preferably with the calibration source (3) being fired about two seconds before the main source (2). The reflected response of the sub-surface strata is recorded and processed to generate seismic data. In one embodiment, the response is recorded with two hydrophone arrays - a short high-resolution array (4) and a conventional main array (5). The method can be used to determine the far-field signature of the main source array (2). It can also be used to obtain a high-resolution shallow seismic section simultaneously with . a deep seismic section. Apparatus suitable for the method is described, and also a method of conducting an underwater seismic survey.

Abstract: In the method, after coordinated transformation the data are written into a frame buffer, which can be addressed in cartesian coordinates, using a storage organisation corresponding to the screen raster, and read out from the frame buffer by row or column and visually displayed on the screen. For the purpose of data reduction without worsening the resolution of the panoramic picture, the increment of the angular coordinate is chosen to be larger by an order of magnitude than the azimuthal resolution of the frame buffer, and is preferably between half the value and the full value of the aperture angle of the scanning member of the panoramic scanning device. In accordance with the azimuthal resolution of the frame buffer, a non- redundant set of cartesian input addresses, whose upper and lower boundaries are determined by the angular coordinate increment, is generated for each pair of values of polar coordinates in such a way that all the memory locations of the frame buffer which are necessary for the panoramic representation can be addressed through the totality of the address records. The same data are written in each case into the memory locations which can be addressed in the address records in each case.

Abstract: A method of heterogeneous reaction is described, comprising reacting a water-soluble component and an oil-soluble component dispersed in the water-soluble component or an aqueous medium containing the same. This dispersion is attained by passing the oil-soluble component through the micropores of a hydrophilic material as it is introduced into the aqueous medium. This hydrophilic material can be shaped into a desired form such as a membrane and a fabric. The flow rate, reaction rate and conversion are easy to control in the present method since the particle size of the oil-soluble component can be appropriately controlled. Furthermore, the present method does not need any stirring power nor an emulsification operation, and thus is advantageous from an economic standpoint.

Abstract: The metal clip (12) of the belt (14) is fastened to a movable element (5) by a retention member (20). The element (5) slides on a rod (1) fixed to the vehicle and which has a spherical portion (1d) situated opposite an annular rubber lining (8) carried by the movable element (5). When a high tensile force is exerted on the belt (14), the movable element (5) is displaced counter to a return spring (7) and the sphere (1d) passes through the lining (8) with friction. When the tensile force ceases, the spring (7) causes the return of the movable element (5) which is slowed down by the passage of the sphere (1d) through the lining (8). As soon as the sphere (1d) has passed through this lining (8), the movable element (5) is freed and the return spring (7) then displaces it instantaneously towards the left. An articulated piece (24) carried by a catch (9) integral with the rod (1) acts on a projection (20a) of the retention member (20) in order to displace the latter axially and thus to free the metal clip (12) of the belt (14). <IMAGE>
