Patent SE-7713735-L (SE)
Inventor: ANANTHA N G
IPC: G11C19/28
Filed: 1977-12-05
Abstract: A two phase charge coupled device memory array wherein the storage capacity is increased by using multiple levels of charge storage within a given cell. A voltage waveform generator capable of producing one of four different voltages is utilized to input and output charge in the multiple level charge method. In determining the level of charge stored within a given cell in the array, the voltage difference between a reference cell and an adjacent addressing cell is used. By determining the voltage level of the addressing cell at which charge overflows the reference cell and counting the number of times it overflows as the voltage generator is successively stepped through its four voltage levels, the level of the original charge input to a given cell can be determined. To make the multiple level scheme independent of process parameters and temperature, the same two cells are utilized for both input and output functions. Various other cells are provided to block and route charge with respect to the array. The method could be utilized with three phase and four phase systems, if desired.

Abstract: In reinforced wires intended for forming and water removal in the wet section of a papermaking machine, it has proved to be important for the forming side of the wire to have a specific appearance, at the same time as the underside of the wire has an appearance matched to the forming side. The peculiarity with the present wire is that the longitudinal threads 1; 5 successively bind over two of five transverse threads 2, 3, 4; 6, 7 on the forming side of the wire, combined with the fact that the longitudinal threads 1; 5 simultaneously bind under one of five transverse threads 2, 3, 4; 6, 7 on the underside of the wire. <IMAGE>

Abstract: This provides a way of producing a sand mould which does not require heavy mechanical presses or violent vibration to ensure sand properly fills tight patterns in a mould. Sand is put into a buffer zone 40 via a feed device 2,3. Below the buffer zone 40 is a flask 10 and pattern plate 14, and the space between the buffer zone 40, the flask 10 and the plate 14 defines a charging chamber through which the sand must fall to produce the mould. This space, and preferably the buffer zone as well, is evacuated. This eliminates air resistance to the falling sand and, as a result, the sand fills the mould properly. The sand is allowed to fall after the vacuum has been established. The reason for evacuating the buffer zone is to bleed the sand of air. It is preferred that the pressure in the charging chamber is reduced further than that in the buffer zone, since a difference in pressure will further accelerate the sand towards the pattern plate.

Abstract: A heated controlled deflection roll equipped with spraying devices arranged in the intermediate space or compartment between the stationary roll support and the roll shell. The spraying devices have walls confronting the inner surface of the roll shell and at which walls there are formed openings which, during operation, form liquid jets. Oil which is infed to the spraying devices can be heated in a collecting container and/or in a tubular conduit. Temperature regulation of the roll shell can also be accomplished by a throughflow or quantitative regulation by means of valves. If there are present a number of temperature zones in the lengthwise direction of the roll shell then different spray devices can be operatively associated with partition walls, from which the liquid is infed to separate collecting containers. From these collecting containers the liquid is again infed, by means of separate pressure lines, to the individual spray devices.

Abstract: Method and apparatus for producing and sealing a can-type pack, consisting of a sleeve-shaped casing 1 and at at least one end thereof an end piece 2,3, where the pack sections are produced from a material suitable for high- frequency welding, having, on the inside of the rest of the pack, at least one layer of a weldable material 5, and wherein the end piece 2,3 is pushed inside the open ends of the casing 1 and fixed by high-frequency welding. The seal is produced in that a material forming an end piece 2,3 is formed with a conically enlarged edge around it, after which the material is pressed into the open end of the casing 1 using a plunger 14 with a conical surface 15 and interacting with a welding tool 8 with a corresponding conical surface 10, wherein the plunger is subjected to a pre-determined pressure, which is maintained until the weldable layer 5 due to the welding begins to take on a plastic fluid form. In this phase the plunger 14 is pushed down with the end section 2,3 slightly, with essentially the same pressure as previously, after which the pressure is relieved while the welded seam sets. The apparatus consists of a tool slide 16 with spring system 21 which supports the plunger 14 and which can be moved down to a fixed stop 18,27, and the plunger 14 is mounted in the tool slide 16 on a vertically movable axis 19 , which can be moved a specifically adjustable distance 22 upwards in relation to the tool slide 16 and then, under the influence of a compression spring 21, a specific distance 20 downwards in relation to the tool slide 16 and in relation to a fixed welding tool 8, which holds the pack casing 1 fast. <IMAGE>

Abstract: A device for adjusting a doctor blade of a printing machine comprising an inking roller facing the doctor blade and adapted to be spaced therefrom by a gap to establish a predetermined ink thickness on the inking roller. Sensors are coupled to the doctor blade for determining the spacing between the inking roller and the doctor blade. Servomotors are coupled to the doctor blade to adjust the position of the doctor blade thereby to adjust the size of the gap. A microcomputer receives signals from the sensors to compare signals from the sensors with the desired gap according to given values of ink thickness and for sending signals to the servomotors to adjust the doctor blade so that the actual distance and the desired distance correspond. The microcomputer also receives the signals from the sensors in non-adjusted state when the inking roller is in contact with the doctor blade to establish this as the zero position of the doctor blade. The zero position can be detected automatically before each resetting of the doctor blade or it can be detected at periodic intervals or by external instruction.

Abstract: The invention relates to a method for separating gaseous elementary mercury from a gas in conjunction with a wet-gas cleaning process comprising a plurality of washing stages. The mercury-containing gas is treated with an aqueous washing liquid conducted in a closed circuit, the liquid containing 0.1-300 mmol/1 mercury (II) ions and at least twice this amount of ions having the ability of forming complexes with mercury (II) ions, the mercury in the gas being oxidized and absorbed in the washing liquid. The invention is characterized in that the treatment process is carried out in conjunction with a gas-cooling process effected after the last washing stage of the wet-gas cleaning process, to form a condensate for absorbing the halogens contained in the gas. The resultant condensate is transferred to the washing liquid and the mercury (II) content of the washing liquid is maintained by contacting the washing liquid with an oxidizing agent for mercury (I) ions. The agent used to oxidize mercury (I) ions is preferably chlorine gas.
