Patent SE-7714820-L (SE)
Inventor: SIGMUND J A
IPC: B25B23/151
Filed: 1977-12-28
Abstract: A tightening and control system is disclosed for automatically tightening a fastener to a predetermined tightened condition in a workpiece, where the fastener is of the type which exhibits more than one installation region on a graph of two tightening characteristics during a complete tightening cycle. Typical of such fasteners are thread tapping fasteners, such as thread-cutting or thread forming types, which first generate a mating thread in a workpiece material and thereafter are tightened in the workpiece to a predetermined load condition. Such fasteners typically exhibit a curve of two related input tightening characteristics, such as torque and rotation, having a thread forming region characterized by a generally linear portion followed by a marked drop off in the slope, an intermediate region having several possible characteristic shapes, and a tightening region having a somewhat similar shape to the thread forming region. Apparatus is generally disclosed for determining the gradient of the torque-rotation curve through which the assembly is being tightened, determining when a first condition indicative of having formed the thread has occurred, and thereafter determining when the tightening region has been reached. The gradient information is utilized to determine when tightening should be discontinued at the predetermined tightened condition. Typically, this predetermined tightened condition may be the yield point of the assembly. Alternatively, the instantaneous torque value at the first condition is obtained and stored, and tightening is discontinued when the instantaneous torque bears some predetermined relationship to the instantaneous torque value at the first condition.

Abstract: METHOD AND APPARATUS FOR THE TREATMENT OF A CELLULOSE-CONTAINING MATERIAL A b s t r a c t Disclosed is a method for the treatment of a cellulose -containing material basically comprising the steps of continuously charging the material together with the solution of reagents into a working chamber and repeatedly machanically compacting the same by means of the cooperation between an inner and an outer working bodies, the outer working body enclosing the inner working body and defining in combination therewith the aforesaid working chamber. The step of repeatedly mechanically compacting the material is effected by imparting to one of the working bodies wobbling and rolling over the other working body through a layer of the material treated, the aforesaid wobbling and rolling being produced by the rotation of a mass unbalanced with respect to the axis of rotation and coupled ratably to one of the working bodies. Also disclosed is an apparatus for practising the above method, which comprises a housing, a rotor made in the form of a body of rotation arranged inside the housing and defining in combination therewith a working chamber, a means for charging the cellulose-containing material together with the solution of reagents into the aforesaid working chamber, a drive shaft and its driving gear. Mounted on the drive shaft are unbalanced masses, 9 while the shaft itself is rotatably coupled to the rotor or to the housing, a portion of the surface of the rotor being designed for repeatedly mechanically compacting the material treated.

Abstract: A method for the production of fiber pulp from lignocellulosic material containing at least 70% spruce or spruce-like material. The method comprises the steps of lignin softening and defibration/refining, the step of lignin softening being performed prior to the step of defibration/refining and comprising impregnating the starting material with a dilute aqueous solution of a lignin softening agent, namely a solution of sulfurous acid, metal bisulfite salts and/or metal sulfite salts in an amount sufficient to provide a defibrated/refined pulp containing an absorbed and bonded amount of sulfonate groups within the range of from 0.06 to 0.75 wt.-%, calculated as Na2SO3 and based on the dry pulp weight. The absorbed and bonded amount of sulfonate groups is balanced to the composition of the starting material and the temperature-pressure conditions in the defibration step to provide a pulp of maximum tensile strength such as to represent a point within the polygon ABGH in FIG. 1. The invention makes it possible to utilize favorable effects, not earlier known, resulting from very low concentrations of the lignin softening agent, and to produce a pulp with high yield and optimum strength and optical properties at a comparatively low energy input in the defibrator/refiner.

Abstract: A filtration or diffusion cell, consisting of adjacent facing support plates and cut diaphragm sections of a semi-permeable diaphragm, for the treating fluids. The support plates are sealed by stringlike or bandlike sealing elements for the separate flow conduction of the fluids. Support plates are provided with channel grooves, for holding the sealing elements. The channel grooves are open toward the plate plane and are provided with perforations through which a sealing material inserted in a flowable state and solidified in the grooves. Several support plates are connected by the sealing material to form a plate holder-like unit, and form seals for separate flow conduction. The support plates are square-shaped, and the front side and the back side of the cut diaphragm sections are subjected to crosswise flow of the fluid. The cut diaphragm sections are supported by grooves and groove crests extending in flow direction of the support plates. The grooves are provided with longitudinally spaced passages leading to the opposite side of the support plates. Flow barriers crossing the grooves under an angle of about 45 DEG  bring about a uniform overflowing of the diaphragm surfaces and prevent shortcuts.

Abstract: In subassemblies having components through which electric current flows, there is the problem of dissipating heat in a pinpointed and highly efficient manner. For this purpose, a cooling element (7) is fitted with a spiral coolant line (20-24), which is located as near as possible to at least one surface (25, 26). The spiral shape of the coolant line (20-24) is particularly suitable, since in most active semiconductor elements heat is to be dissipated by a circular surface. A method for producing cooling elements is suitable, in particular for mass production on a pressure die-casting machine. In this process, the coolant line is positioned during the actual casting process by means of supports (15) and a controllable core (16a). <IMAGE>

Abstract: A method and a device are proposed for the injection of very small amounts of samples into cells (74) with the aid of a microcapillary (10).

Abstract: The invention relates to a method of recovering chemicals from chloride-containing green liquor by precarbonating the green liquor by means of flue gases into hydrosulfide and soda, by removing hydrosulfide from the precarbonated solution in the form of hydrogen sulfide, by evaporation crystallizing the chloride- and soda-containing solution in order to separate the chloride salt from the alkaline solution. In order to reduce releases of hydrogen sulfide, the produced hydrogen sulfide is absorbed into a soda solution and/or an alkaline solution in order to produce a solution suitable for the preparation of white liquor, whereas the hydrogen sulfide which remains unabsorbed is returned to the precarbonation stage, in which the hydrogen sulfide is absorbed substantially completely. By means of the invention it is possible to achieve a closed cycle of chemicals without the chloride load of the system increasing, and at the same time the chloride is recovered and returned to the bleaching.
