Abstract: Equipment for filtering liquids incorporating a filter chamber which includes a granular or particulate filter material, on which precipitates etc. from the liquid settle out. The filter chamber is divided into two part- chambers A, B by a partition 13 which forms an overflow, and these part-chambers are designed to operate alternately, each having an upper inlet for unfiltered liquid and a lower outlet 19, 20, 22, 23 for the filtered liquid. One of the filter part-chambers A contains a granular or particulate filter material with a mean volumetric weight which is lower than the density of the liquid to be filtered. Inlets and outlets 14,15,19,20,22, 23 for the liquid are fitted with valves 17,18,21,24 for controlling the liquid level in the respective filter part-chambers A, B as required, so that it would be possible to raise the liquid level and allow the filter material to float up or be drawn with the liquid flow and thereby be carried over from one of the filter part- chambers A to the other B. The valves 17,18,21,24 can be automatically controlled. The filter material can be made up of light granular clinker material. A method for filtering liquids by allowing the liquid to percolate through a bed of granular or particulate filter material situated in a filter chamber A, the mean volumetric weight of which material is essentially similar to the density of the liquid. During the filtering process, the liquid is maintained at a lower level than the surface of the filter bed. For cleaning of the filter material, the liquid level is raised from time to time so that the grains or particles of the filter material, by floating or being drawn with the liquid flow over an overflow 13 or similar, are carried to an adjacent filter-material chamber B which is thereafter used until the filter material needs to be cleaned again. For this purpose, it is then carried back to the first filter-material chamber. <IMAGE>

Abstract: A resistor particularly useful as a self-regulating fluid heater has passages extending through a body of ceramic resistance material of positive temperature coefficient of resistivity (PTC) and has ohmic contact coatings formed on the inner walls of the passages. The passage walls define thin webs of the resistance material between adjacent passages and are of uniform thickness end to end. Slits located in the walls at the ends of selected passages accommodate electrically conducting means which interconnect the contacts in selected pairs of the passages. In that way, predetermined groups of the contacts are interconnected at respective ends of the resistor so that when the groups of contacts are connected in a circuit, electrical current is directed through the thin webs of resistance material between contacts of opposite polarity in adjacent passages, thereby to heat the resistor to self-regulate its temperature to efficiently generate heat for transfer to a fluid directed through the passages. Electrically conductive coatings are applied to the ends of the resistor body to be received in the slits and the body ends are then abraded for removing coating material outside the slits, thereby to interconnect the desired groups of contacts.

Abstract: A welding rectifier is connected to an a.c. power supply. The rectifier delivers a pulsating voltage which during a part of a period is too low to maintain the arc established between a welding electrode and a work. A main winding of an ironcored inductor is connected in series with the rectifier, the welding electrode and the work. An auxiliary winding is wound onto the iron core and connected in series with a capacitor. The auxiliary winding is connected to the main winding so that the two windings, when passed by a current, supply ampere-turns in the same direction. The auxiliary winding and the capacitor are connected in parallel with the main winding and the arc. The capacitor is also connected in series with a charging rectifier connected to the a.c. supply. The capacitor is discharged through the auxiliary winding and the main winding into the arc, when the voltage delivered by the welding rectifier is too low to maintain the arc.

Abstract: The invention relates to an oil damping device intended to be used in operating mechanisms for puffer-type SF6 breakers where there is a risk that the contact movement is reversed during an opening operation with great current. The damping device comprises a piston which is attached to a piston rod and is movable in a damping cylinder. The damping device is double-acting and the movement is damped against the two end positions of the piston (corresponding to the closed and open position, respectively, of the circuit breaker) by forcing oil to flow out through restricted openings in the damping cylinder. The damping cylinder is movable inside an additional cylinder between a rest position and a lock position. Upon an opening operation, the damping cylinder is automatically brought to the lock position where it is temporarily retained by a latching member. With the damping cylinder in this position, the restricted openings arranged on the closed position side of the piston are closed, such that the piston is prevented from moving in the closing position. By providing the damping device with a nonreturn latching member, a higher breaking capacity of the circuit breaker can be achieved.

Abstract: A pressurized water nuclear reactor comprises a reactor vessel arranged in a pool made in the form of a pressure vessel, the pool being filled with a strongly neutron-absorbing liquid, for example borated water. The reactor vessel, in addition to being connected to a primary system, is provided with a lower shutdown opening, arranged below the reactor core, for pool liquid and with an upper shutdown opening, arranged above the core, for pool liquid. The reactor vessel, the two emergency shutdown openings and the liquid-filled space of the pool are included in an emergency shutdown circuit, in which the difference in density between the liquid in the pool and the relatively warmer cooling water in the reactor vessel constitutes a pressure difference which by itself, or alternatively with the aid of some other pressure generation means, balances the pressure drop of the reactor cooling water across the core in such a way that no significant flow circulates in the emergency shutdown circuit during normal reactor operation.

Abstract: To be able to control the contrast in photographic copying, especially for colour, it is desirable to let the whole of the original's tone spectrum be used whilst not overstepping the copy material's full tone spectrum.Contrast regulation has so far been carried out using three different techniques, either in combination or on their own:1. copying via an intermediary original2. copying through a half transparent mask, which is adapted in contact with the original3. prior illumination of the copy material with white light.Contrast control with the help of the shadow mask method occurs via:- exposure of the copying material is divided up into two or more steps,- each exposure step involves a definite part of the original's scale of tone which can then be controlled for suitable lighting on the copy- those parts of the original scale of tone which are not included in a defined exposure step are shaded by a photographically produced mask which is totally opaque in those parts of the original's scale of tone and transparent in the other parts.- the mask is produced via exposure of a defined area in the light path of an optical copying arrangement (enlargement unit), is developed and put back in the exact same spot.- the mask represents a picture of non-definition in this part of the light path.- the mask's placement in the light path decides how fine details in the original are broken up by the mask's shadow.

Date Jun. 21, 1984.The present invention relates to a method and apparatus for measuring the content of suspended substances in a flowing medium by illuminating the medium with light from a light source. Reflected light from the medium is detected by at least two detectors, at least one of which measures directly reflected light while the other detectors measure multiply reflected light. The detector for detecting directly reflected light is located such that a linear relationship is established between its output signal and the concentration of the flowing medium. The other detectors are located such that their output signals will be essentially constant in relation to the concentration of particles in the flowing medium within a large range. The measuring scheme provides for obtaining the quotient of the signal provided by direct reflection divided by the signal provided by multiple reflection. A measure of concentration of the flowing medium is provided which is independent of disturbing factors such as for example pulp color.
