Abstract: An eddy current power absorption unit has a particular cooling system which alleviates overheating of the unit and its individual components. Cooling conduits comprising a plurality of meandering paths, each including axially oriented flow lines, are disposed close to the heated components to uniformly remove heat therefrom. The flow velocities at the entrance and exit of the meandering flow paths are generally equal to one another.

Abstract: Through a method for transferring forces and/or moments between a rotatingly powered test stand and a test specimen and through an apparatus for carrying out the method, data is obtained which is identical to actual service data of a vehicle as it is driven on the road. This is accomplished without need to resort to additional empirical factors. The data is obtained by suspension of the mass of the driven test specimen with the test machine and through a torsion elastic connection of the test specimen with the test machine.

Abstract: In a process for the transportation and accumulation of pallets, guide or retaining rollers are arranged on a traction element on an axle. Elastic guiding of the support and retaining rollers in relation to the traction element is accomplished and elastic centering in relation to the traction element results in a straight line operation with conveyors used for the transportation of pallets and large area objects. Reduced maintenance and wear, reduction of noise level of the conveying equipment, prevention of acceleration and braking jolts to the goods to be conveyed and assured parallel guiding of conveyor belts are advantageous of the present invention. Clear centering of the support rollers and of the retaining rollers in relation to the conveyor is also obtained with a device for the transportation and accumulation of pallets as a result of a lagging of the retaining rollers and support rollers behind the axle mount therefor.

Abstract: A machine for mass-centering rotors consists of a pair of spaced apart headstocks, each rotatably supporting an adapter disc, and each equipped with a device for the application of machining centers in a rotor being investigated. Adjuster mechanisms on the adapter discs are removably secured to the ends of the rotor, whereby rotation of the discs causes the rotor to rotate. The headstocks are connected to a vibration sensing vibratory bridge arrangement which picks-up the vibration of the rotor as it rotates. The adjuster mechanisms shift the axis of rotation of the rotor until the unbalance thereof is zero or at a predeterminable level. Rotors of differing length are easily positioned between the headstocks which move toward and away from one another.

Abstract: In a method and apparatus for measuring deformations of test samples in testing machines, a test sample (4) is clamped into force transmitting units (10, 11). A light source (1) emits a light beam (2) which is reflected from at least one mirror (6, 6') arranged on the force transmitting units (10, 11) to impinge upon a position detector (7) which generates an output signal. The output signal is input to an electronic evaluating circuit (8) to determine the location or rather the location movement of the point of impingement of the light beam on the position detector. Preferably, but not necessarily, each force transmitting unit (10, 11) includes its own mirror (6, 6'), whereby the light beam (2) emitted by the light source (1) is reflected in sequence by the first mirror (6) of the first force transmitting unit (10) onto a second mirror (6') of the second force transmitting unit (11) and then onto the position detector (7).

Abstract: The quantity of a flow of bulk material passing over a measuring wheel is continuously measured by measuring the load r.p.m. of the wheel or of a motor driving the wheel and the power output torque of the motor. The resulting r.p.m. and torque values are used for calculating the quantity. Interfering influences are substantially eliminated by using a correction value in the calculation. The correction value is based on the inertia moment of all rotating components of the system and on variations in the load r.p.m. Load r.p.m. and power output torque measuring devices provide data to a microprocessor for the calculations for achieving a high measuring precision even when the r.p.m. varies.

Abstract: In a test sample clamping apparatus for testing machines, having a clamping head or chuck and a force sensor (2) arranged on the chuck, testing forces are measured with a force sensor and displacements or test sample deformations are measured simultaneously with a light deflection. Thus, rapid test procedures such as fast tensile rupture tests are made possible. The clamping head or chuck includes a base plate (3), one side of which receives or holds clamping elements (15) and the other side of which clamps down the force sensor (2) against a support. A mirror surface (8, 8') is arranged on the base plate (3) or on other appropriate surfaces of the clamping head so as to reflect a ligth beam (10) emitted by a light source (9) onto a position detector (11). In order to measure a deformation caused displacement of the clamping head and correspondingly of the test sample (4), an electronic evaluating circuit (12) evaluates the position dependent output signal of the detector (11).

Abstract: In a method for continuously determining the delivery rate of a stream or flow of loose bulk material and/or for continuously dosing such material, the loose material is caused to travel along part of a circular path and is then removed from that circular path after travelling at least around a portion of a circle. The centrifugal force exerted by the loose material on the axis of rotation is measured and used to deterine the delivery rate. The centrifugal force is measured by sensing an excursion of a rotational axis of a measuring wheel caused by the centrifugal force exerted by the loose material continuously fed onto and removed from the rotating measuring wheel such that the material travels through a semicircle. Before being fed onto the measuring wheel, the material may be accelerated to the wheel's velocity. The centrifugal force resulting on the wheel axis is measured.

Abstract: An unbalance measuring station (1) is disclosed toward which a rotor to be balanced is carried by a transport system (7). The station (1) contains an unbalance measurement unit (10) as well as devices (11, 12) for loading the rotor (6) into the unbalance measurement unit. The unit is essentially arranged above the plane of the path of movement of the transport system (7). The unbalance measuring station (1) is particularly suited for use in connection with transfer and assembly lines.

Abstract: A roller deck for the angular deflection of a pallet comprises a basic frame and a lift frame which is movable relative to the basic frame. Both frames have rollers for supporting a pallet. A pneumatic lifting device between the frames elevates the lifting frame upon activation. With such pneumatic lifting, replacement of damaged lifting elements is accomplished without separating the basic frame and lift frame. Moreover, such lift elements are maintenance free during operation.

Abstract: A stable reference platform is securely anchored within the passenger compartment of a motor vehicle. The positioning and anchoring of the platform is accomplished without removing or engaging the passenger seat, and in a manner which avoids soiling and/or damage to the passenger compartment. The reference platform functions to support devices used to automatically operate the vehicle during testing thereof.

Abstract: In a method of supporting the bearing of a bearing support structure during balancing of a rotor, the bearing and the rotor journal in the bearing are permitted to rotate about the vertical, and transverse axes of the rotor journal. A spring arrangement is positioned between the bearing and vibration transducers for transferring unbalance information from the rotor being investigated to the vibration transducers. The spring arrangement allows the bearing and rotor journal to move without hindrance about the vertical, and transverse axes, such movement being caused from misalignment of the rotor journals with the axis of rotation of the rotor. Coulomb's friction is thereby eliminated for the purpose of avoiding excessively high constraining forces, spring realignment forces and frication forces.

Abstract: The spread of particles which might otherwise be unevenly deposited upon a moving surface is equalized in accordance with a rated density distribution of the particle mass. The density distribution is determined across the particle mass and the particle distribution is varied so that the stream deposited upon the moving surface is uniform and in accord with a given density distribution.

Abstract: An eddy current brake has a particular cooling system which alleviates overheating of the brake and its individual components. Cooling conduits comprising a plurality of parallel flow lines are disposed close to the heated components and the arrangement is such that heat is uniformly exchanged and removed from the brake. Cooling medium flows through the conduits along the plurality of flow lines and the distribution of cooling medium is such that the velocity of flow is substantially equal along each line.

Abstract: Test stands for power plants generally include a power absorbing unit for absorbing the power of the plant under test. The allowable measuring speed of the power absorbing unit depends on permissible additional weight on the coupling flange which serves to interconnect the power plant to one end of the power absorbing unit. In order to avoid the detrimental influence of increased amplitudes caused by torsional resonances the weight that exceeds the permissible weight is transferred to the opposite end of the power absorbing unit and the torque of the power plant is introduced in dampened form at that end.

Abstract: In a procedure for the longitudinal orientation of chips, particularly during the manufacturing of OSB boards, spaced apart discs are located on rotating shafts sequentially one after the other. The discs are positioned above a forming belt that receives the chips after they are oriented by the discs. The discs are located on each of the shafts, and these discs together with the longitudinal side walls of an enclosure for the discs, function to longitudinally orient the wood chips to the point of deposit upon the forming belt.

Abstract: Method and apparatus for taking into account position inaccuracies of attachment surfaces for later attachment of components, that possess mass on a rotor, such as a crankshaft with crankpins, during balancing of the rotor. The attachment surfaces such as crankpins function as sites for the later assembly of components that possess mass. Differences between the ideal and actual positions of each attachment surface are determined and are taken into account during the balancing procedure.

Abstract: A procedure is described for the balancing of rotors without journals, as well as an auxiliary bearing arrangement used to accomplish the balancing of such rotors. Fluids function to separate the rotor being balanced from the journal exterior of the bearing arrangement and also to separate the rotor from the support surface of the bearing arrangement. A high level of precision is achieved while avoiding fixed or expanding mandrels. Improvement of the automated operation of balancing machines of this type is possible without wear on the machine. Also, additional disturbance frequencies are avoided.

Abstract: A device for the orientation of chips into a preferred direction during production of particleboard includes parallel vertical guide surfaces arranged at a distance from one another and horizontal parallel rotating shafts arranged at a distance from one another above the guide surfaces. Each shaft has spacer rings and pin plates that collectively provide pin roller arrangements for the orientation of chips in a preferred direction as the shafts rotate. Chips are discharged without congestion between the guide surfaces and without damage to the pins of the pin rollers. Free passage is also possible for chips to be oriented in the production of OSB boards.

Abstract: In a method for constructing a weighbridge, the weighing platform is made of reinforced concrete and is built in a previously prepared foundation ditch which is used as a mold for the weighing platform. After the hardening of the foundation ditch (1) separating means (10, 11) are placed in the foundation ditch (1) for separating the weighing platform from the ditch (1). Subsequently, the weighing platform is cast in the foundation ditch (1). A weighing cell assembly for a weighbridge, which is particularly suitable for use when performing this method, includes a weighing cell, a support element (6) for the weighing cell and a tubular structural member (8) which can be connected to the weighing platform and holds the support element (6). The weighing platform can be supported on the weighing cell through the tubular structural member.
