Abstract: An austenitic stainless steel which in wrought or cast, and annealed, condition exhibits excellent galling resistance, excellent stress corrosion resistance in chloride-containing environments, good resistance against intergranular corrosion, good high temperature oxidation resistance, and a high work hardening rate. The broad composition range is, in weight percent, about 13 to about 19% chromium, about 13 to about 19% nickel, 0.5 to about 4% manganese, 3.5 to about 7% silicon, up to about 0.15% carbon, less than 0.04% nitrogen, about 0.05% maximum phosphorus, about 0.05% maximum sulfur, and balance essentially iron except for incidental impurities. The steel can be readily worked with conventional equipment and has particular utility for applications in which moving metal-to-metal contact, corrosive attack and/or elevated temperature are encountered in combination. The steel can also be cast into articles of ultimate use, or utilized in powder metallurgy techniques.

Abstract: A processor has a working receptacle with a part-spherical internal wall. There is a working element which can execute either simple rotary motion about a single axis or planetary motion about two axes which intersect at the geometric center of the part-spherical internal wall. There are control means for enabling simple rotary motion or planetary motion to be effected. Dough is worked by hydrating the mix and then completing development at a substantially greater energy input rate. The hydration stage can be considered as being carried out at such an energy input rate that substantial relaxation of the dough occurs, the development completion stage being considered to be carried out at an energy input rate at which no substantial relaxation of the dough occurs. Alternatively, in a more specific idea, the hydration stage is carried out using a working element with a planetary motion and the development completion stage is carried out using a working element with simple rotary motion.

Abstract: A puffer type circuit breaker is provided with a pump means consisting of a piston and a cylinder for producing a blast of arc-extinguishing gas. The piston is axially displaceable against a spring force, and the cylinder is joined to the movable contact of the circuit breaker and arranged, during a breaking operation, to compress the gas in the cylinder space of the pump means to achieve a blast of extinguishing gas towards the contact area. A spring holds the piston pressed against a stop in the closed as well as the open position of the circuit breaker. The spring has such a high pre-stress that the piston only moves upon breaking of short-circuit currents.

Abstract: An articulated vehicle including a front member having at least two axles, the forwardmost one of which is steerable, and a rear member, connected to the front member by a pivotal joint, having at least one axle and an engine for driving that axle. A first transducer produces a signal representative of the angle between the steerable axle and another axle of the front member, and a second transducer produces a signal representative of the buckling angle between the vehicle members. A comparator receives the transducer signals and produces a signal in the event that the actual buckling angle is less or greater than a theoretical buckling angle, the latter being determined by the signal from the first transducer. A device, such as a piston and cylinder device, responds to the comparator signal by producing a torque about the pivotal joint to increase or decrease, as the case may be, the actual buckling angle so that it approaches the theoretical buckling angle.

Abstract: A box-like recess between the condylar portions of the femoral component has a transverse convexly curved cam follower portion at the posterior extremity of a superior wall which engages a concave cam surface at the inferior portion of the posterior surface of a tibial post that extends up from the plateau surface of the tibial component into the recess. The camming action between the cam follower and cam surface forces the zones of contact between the condylar portions of the femoral component and concavities in the tibial component posteriorly as the leg approaches full flexion, thereby increasing the range of flexion without interference between posterior surfaces of the femur and the tibial component and preventing anterior dislocation of the femur. The plateau of the tibial component slopes inferiorly and posteriorly, also to increase the range of flexion without interference.

Date Nov. 11, 1982.In displaying on a viewing screen an image generated by output signals from a radiation-sensitive detector, e.g., an infrared detector, it may occur that weakly contrasting details in the image are lost when the light intensity of the image covers too great an intensity range. In one method of avoiding this loss of details, the amplification of the low-frequency portions of the video signals is regulated adaptively by calculating two statistical parameters, characteristic for the statistical properties of the signal values, and adjusting the amplification such that a selected image intensity corresponds to the calculated parameters.

Abstract: A calender roll whose shell consists of ferromagnetic material is heated by several groups of electromagnets which are mounted within the shell on a stationary carrier and whose pole shoes are adjacent to the internal surface of the shell. The temperature of the external surface of the shell is monitored at several locations as considered in the axial direction of the roll, and the resulting signals are compared with reference signals denoting the optimum or desired temperatures at such locations. Signals denoting the differences between the actual temperature signals and desired temperature signals are used to regulate the characteristics of electric current which is supplied to the windings of the electromagnets. Each electromagnet of each group can be regulated independently of all other electromagnets. Alternatively, two or more electromagnets of each group or entire groups of electromagnets may be regulated simultaneously. Additional electromagnets are provided to heat the end portions of the shell. Alternatively, such end portions can be heated by the rotors of electric motors which rotate the shell. The characteristics of current which is supplied to the windings of certain electromagnets can be influenced by signals which denote the magnitude of flexural stresses upon selected portions of the shell so that the corresponding electromagnets oppose deformation of adjacent portions of the shell.

Abstract: The invention relates to a method for crushing and an apparatus for use in performing the method. The crushing is done by causing the crushing elements 6 belonging to the rotor 2, which are mounted so that they can rotate about their shafts 7 and are moveable to a restricted degree in the radial direction of the rotor 2, to move past a curved counter-surface 3 at the rotation of the rotor 2, in such a way that the material to be processed is crushed when it lands between the rotating crushing elements, acted on by the centrifugal force, and the counter-surface 3. The most essential characteristic according to the invention is that the crushing is done in a crushing chamber 1 defined by an essentially cylindrical or conical counter-surface 3 by feeding the material through an upper inlet end 11 into the crushing chamber 1, by crushing the material with a rotor 2 fitted in a crushing chamber 1, the material being moved downward in the crushing chamber 1 by the force of gravity or by the gravitational and centrifugal force, and by removing the crushed material at the bottom outlet end 12 of the crushing chamber 1. The particle size of the crushed material is regulated by adjusting the distance between the counter-surface 3 and the crushing elements 6, for example by constructing the counter- surface 3 from separate disc elements, which can be bent towards the crushing elements 6. <IMAGE>
