Abstract: High tension voltage is applied to the X-ray tube via a number of control units that are connected in series with the positive and the negative supply, respectively. Each control unit (11) includes a transistor (27) which conducts according to the difference between the actual level and the required level of voltage as determined by a comparator (20). The actual voltage level is derived from a potential divider (22) connected between the output terminals  (A+, A-) of the unit and the required level is derived from control inputs (E+, E-). These are produced by regulators in connection with a reference voltage. The required level for the next control unit in the chain is derived from the output volt-age of the preceding control unit. Each unit is provided with a voltage limiting circuit for short circuit protection.

Abstract: The electromagnetically operated pilot valve (182) of an electrohydraulically actuated fuel injector is used to close and temporarily open the outlet side of an orifice (38) to close and temporarily open a hydraulically operated injector valve, depending upon electric pulses of a predetermined duration applied to a solenoid (172). In order to improve the controllability of injection events, it is important that the pilot valve (182) switch-over movement takes place as soon as possible after the end of an electric pulse. The closing bias of the pilot valve (182) is provided by a spring (196). To reduce the release time of the pilot valve (182), a stop member (184) placed coaxially to the stem (180) of the pilot valve (182) and protruding beyond the pole face (148, 150) of the solenoid (172) is provided.

Abstract: The invention relates to process and apparatus for three-dimensional surveying by triangulation with a laser beam source. Pursuant to known practice, a laser beam scans a scene to be surveyed, by means of controlled rotary positioning of a mirror. The reflected beam is detected by a linear array of photosensitive receptors, enabling the location of the illuminated point to be determined by triangulation. Significant to the invention is the use of a secondary light source for precision measurement of the angular location of the scanning mirror, rather than relying upon controlled positioning of the mirror, which is much less accurate.

Abstract: The invention relates to a method and apparatus for separating knots. In particular the method and the apparatus are meant to be used in separating knots from fibre suspensions of the wood processing industry. The knotter according to the invention uses a profiled screen cylinder (5) with which it has been found from performed tests to be most preferable to feed the pulp from the connections (2) in the direction of rotation of the screen cylinder and also to discharge the reject from the connections (4) and the accept from the connections (3) of the cylinder (5) in the direction of rotation. As a result, there is not only less wear of the screen surface, but also a significantly smaller consumption of power per pulp ton than in the apparatuses in accordance with the prior art.

Abstract: In a cryogenic air distillation process for producing medium-to-high purity oxygen plus optional coproduct argon, a new process sequence results in more efficient distillations at reduced supply pressure and full O2 recovery. Reforming to FIG. 2, a minor stream of supply air is additionally compressed by compander 204, cooled, and then reboils column 201 by total condensation in reboiler 205. The liquid air is split into two intermediate reflux streams, one for each column 201 and 202, valves 206 and 207, thereby improving the efficiency of both columns. The air condensing in 205 is somewhat hotter than that supplied to 202, due to its higher pressure, which permits a reduction in the main supply pressure.
