Abstract: A tomography data acquisition system in which the signal processing of signals from a radiation detector is a function of the angular position of the detector relative to a center path from the radiation source through the center of a tomography subject, and which results in system hardware savings. The information content of detector signals derived from radiation paths progressively outward from the center path is progressively less than the information content of detector signals derived from the central radiation path. The sampling rate of the outward detector signals can be lower without loss of information. The resolution of the outward detector signals can also be lower, and as desired, either the sampling rate or the resolution or both can be varied in accordance with the position of the detector in relation to the center path.

Abstract: This invention relates to sequential blasting utilising electronic circuitry to steer detonating pulses to successive detonators. Modules are provided which contain a two- terminal element that has the characteristic that in its first normal state it has a high resistance in at least one direction and it may be changed into a second state in which it has a low resistance in both directions by a suitable pulse. Further, a detonating signal does not flow from one power line to the other through the particular module that is being addressed, but from one side of one module through a connecting link and then through the other module. Thus, each module has an input steering terminal and an output steering terminal, with the output steering terminal of each module connected to the input steering terminal of the next module. Then in use, current flows from one power line to a power terminal of one module, through its output steering terminal to the input terminal of the next module, through that module and to the other power line. Thus, with each detonating pulse, a detonator is fused and one of the elements passes into its second conducting state. As the detonator goes into a non-conducting configuration the next pulse is steered via the element that is now conducting to the next module.

Abstract: A device for matching a hybrid circuit to a telecommunication line as well as an application of the method and a device for carrying out the method. The hybrid circuit (G1) connected with its bidirectional main branch to the telecommunication line is terminated on its side opposite the main branch with a balancing network (NB1) which contains variable impedances that can be controlled by a microcomputer (MC1). A test signal with a constant signal level is fed to one sub-branch of the hybrid circuit (G1) and the component of the signal level crossing over into the other sub-branch of the hybrid circuit (G1) in dependence on the transhybrid loss is continuously measured. Before each measurement the variable impedance is set to another value by the microcomputer (MC1) and the measured values of the crossover component of the signal level obtained are compared with each other. In each case the smallest measured value associated with a specific impedance value is stored and, after a predetermined number of measurements, the balancing network is permanently set to an impedance value corresponding to the smallest measured value of the crossover component of the signal level. <IMAGE>

Abstract: The lines representing each edge of each face of each object of a model for producing a multiple object image are segmented at line of sight intersections with other lines representing contour edges of visible faces. Each resulting edge line segment is checked against all visible faces to determine which are visible and which are invisible, and information on visibility is stored together with detailed information on each edge line segment for each object. The model is modified by changing the number of component objects and after each change, the edge line segments are checked for visibility only with respect to the changes associated with the changed component objects. This results is a substantial reduction in the required number of comparisons between segments and faces as compared to prior methods.

Abstract: The vertically operating machine tool has at least one tool slide (14) guided on a wall (18). The workpiece is transferred between at least two working positions (10) on one side of the wall (18) by means of a manipulator (26), mounted on the other side of the wall, through at least two wall apertures (20, 22). The manipulator (26) has a two- piece bending arm (32) which can be rotated about a pivoting axis (36) and whose bending movement is derived from its rotary movement by positive guidance. Uniaxial control for the manipulator is therefore sufficient despite the complicated transfer of the workpiece in both directions through the wall (18) and along the same. <IMAGE>

Abstract: The quantity flue gas residues purification plant, which have to be put into landfill and which also contain significant amounts of reactive chemicals in addition to pollutants, is reduced when the dusty residues are slurried together with fresh chemicals and added to the scrubbing fluid of a wet-operating flue gas purification plant, the still reactive fraction of the chemicals present in the residues serving for the neutralisation and activation of the scrubbing fluid and thus being substantially more completely utilised than is possible in dry processes. In this way, it is not only possible to reduce the quantity for landfill, but also to achieve considerable savings in the consumption of fresh chemicals. <IMAGE>

Abstract: A novel class of heterocyclic polymers and copolymers containing the 2-imidazolin-5-one ring structure is described. These polymers are prepared by reaction of bisazlactones and diamines, with or without suitable condensation monomers; the resultant polyamides are then thermally cyclodehydrated in the presence of a catalyst to produce the imidazolinone-containing polymers. Many of the poly(imidazolinones) are water soluble and therefore find utility in various aspects of water treatment, or in paper or fabric sizing.

Abstract: The invention relates to a process for glueing together products made of paper, plastics films, etc., especially for glueing together letter-sheets (12'), such as single-sheet letters (12), i.e. mailers. With such products it was hitherto necessary, if a closed envelope was to be formed, to apply an adhesive to certain predetermined areas, preferably edge zones (1, 2, 3; 4, 5, 6; 4'), and dry it. On passing through an electrostatic copier or laser printer it was a disadvantage that, as a consequence of the heat exerted, the thermoplastics adhesive material was activated and caused damage or interference within the copier or printer. This disadvantage is avoided with the novel process in that the adhesive areas (1, 2, 3; 4, 5, 6; 4') are produced by means of electrostatic charge images and in that the adhesive is a pulverulent toner composition as used in electrostatic copying, laser printing or the like. <IMAGE>

Abstract: In a weapons training simulator, laser radiation is output via optics (28) to simulate the firing of a round, and reflected radiation received via a conjugate path to assess the effectiveness of the shot. In the event of a miss a scan of the target area is required to provide fall of shot information. The scan is performed by controlled movement of the output faces of fibre optics (23, 24, 25) flexibly coupling to fixed sources (20, 21. 22) and of the input face of a fibre optic (200) flexibly coupling to a fixed detector (201). The problem of the bulk and inertia of prior art systems is improved by the remote location of lasers, drive and control, which may be conveniently separated for service or replacement without disturbing the optically aligned input and output faces. A further improvement is that vertically aligned multiple sources may be employed without undue weight penalty, yielding elevation information from a lateral scan.
