摘要： A hydrostatic or hydrodynamic shaft seal comprises a ring revolving with the shaft and an axially movable static ring which is sealed against the housing by two O-rings and forms, with the revolving ring, radial seal gaps. An incompressible fluid flows and stabilizes the seal gaps and the static seal ring has a cavity for receiving the stopping or cooling liquid. A number of tensioning spring elements are arranged on the circumference or end of the static ring which take support against a ring which serves as a pressure limiting valve.

摘要： A method and device for automatically steering a trackless vehicle along a routing or guide line. A scanner senses the position of the longitudinal centerline of the vehicle with respect to the guide line and produces a position signal. A datum transmitter produces a datum signal. A comparator compares the two signals and produces a difference signal which is used by a control unit to produce a steering signal. In producing the steering signal, the device distinguishes between influences on the vehicle position caused by interference, e.g., wind gusts and rough roads, and influences caused by curvature of the guide line. The steering signal causes adjustment of the steering angle of the vehicle to minimize the distance between a reference point on the longitudinal centerline of the vehicle and the guide line.
摘要翻译：一种用于沿着路线或引导线自动地转向无轨道车辆的方法和装置。扫描仪感测车辆相对于引导线的纵向中心线的位置并产生位置信号。基准信号发生器产生一个基准信号。比较器比较两个信号并产生差分信号，该差信号由控制单元用于产生转向信号。在产生转向信号时，该装置区分由干扰引起的对车辆位置的影响，例如阵风和粗糙道路，以及由引导线的曲率引起的影响。转向信号引起车辆转向角的调整，使车辆纵向中心线上的参考点与引导线之间的距离最小化。

摘要： To connect two machine elements which are dynamically loaded by means of tension bolts, the bolts are carried through bores in the machine elements which are somewhat wider than the diameter of the bolts to form a cylindrical chamber, leaving a cylindrical gap surrounding the bolt; the chamber is entirely filled with a damping substance, such as a foamed material, or lubricating oil, particularly pressurized lubricating oil or the like. Preferably, the gap is about 2 to 8 percent of the diameter of the tension bolt, has a length at least three times the diameter of the tension bolt, and is located approximately centered between the points of force application on the tension bolt, to dampen transfer of vibrations, but permit slow bending, below the yield point of the bolt, within the chamber.

摘要： Workpieces which are formed by the build-up of weld metal are treated and cooled by directing a fluid such as water in a large stream so that rapid and intensive cooling of the surfaces of the workpiece is achieved by creating a laminar water flow. A water quantity is directed to reach the workpiece surface in a laminar flow and it is permitted to flow over the workpiece as the water is sucked off before it reaches its boiling point at the rate of flow to the workpiece and away from the workpiece being sufficient to prevent the formation of steam. The water which is employed is advantageously recooled to its initial temperature by the withdrawing effect created by an air fan.

摘要： 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.
摘要翻译：一种铰接式车辆，包括具有至少两个轴的前部构件，其中最前面的一个是可操纵的，以及通过枢转接头连接到前部构件的后部构件，其具有至少一个轴和用于驱动该车轴的发动机。第一传感器产生表示可转向轴与前部构件的另一个轴之间的角度的信号，并且第二换能器产生表示车辆构件之间的弯曲角度的信号。在实际的屈曲角小于或大于理论屈曲角度的情况下，比较器接收换能器信号并产生信号，后者由第一换能器的信号决定。诸如活塞和气缸装置的装置通过产生围绕枢转关节的扭矩来响应比较器信号，以根据情况增加或减小实际的屈曲角度，使得其接近理论屈曲角度。

摘要： To prevent differential deformation and damage, upon operation of large internal combustion engines, such as large Diesel engines, the cage structure is formed with a central valve seat and a lateral passage for inlet and exhaust gases to the cylinder of the internal combustion engine, and the wall opposite the lateral passage is formed with a diametrically interrupting slit extending at least in part transversely to the longitudinal axis of the cage (and hence of the valve), leaving a depending tongue to delimit the valve cage, the interrupted wall structure preventing unbalanced thermal and vibration stresses from interfering with the structural stability of the valve cage.
