  • Apparatus and method for driving a vehicle with a plurality of motors
    Patent number: 5879265
    Abstract: A method and apparatus for the operation of a vehicle with a plurality of electric motors includes an electric motor assigned to each wheel of an axle of the vehicle. Attached to each of the electric motors is a shiftable transmission (at least two-speeds). Shifting of a transmission is performed as a function of the total efficiency of the particular motor when reaching a predetermined shifting point. The transmissions attached to the electric motors are shifted, delayed in time. The shifting of the transmission attached to a first electric motor is monitored and the shifting of a transmission attached to a second motor is performed only when the shifting of the first transmission is completed. No interruption of the traction force occurs in the drive system.

  • Device for dewatering suspensions
    Patent number: 5879551
    Abstract: A device for dewatering suspensions such as sludge or similar dewaterable goods contains several rollers and filtering webs that follow a sinuous path around the rollers. The width of at least one pressure gap, as well as the force which is applied on the goods to be filtered in this pressure gap, may be adjusted by sliding or swivelling so that the ratio between linear pressure and surface pressure can be adapted to the properties of the goods to be dewatered. By influencing this ratio it is possible from a standard model to cover a wide range of applications by simple and economic means, so that the cost-effectiveness ratio is improved.

  • Flow control especially for instantaneous water heater
    Patent number: 5875807
    Abstract: Fitting, especially for a continuous flow water heater.The submitted invention takes as its basis the problem of developing a fitting of the named type by which the formation of calcareous deposits on the rod protruding from the water control housing is lessened and the influence of such calcareous deposits on the controller action is completely eliminated.The problem is solved in that within water control housing (2), the control motion of membrane (24) is transmitted to a lever (3) whose center of rotation forms a shaft (4), rigidly connected to this lever (3) and whose pivot is sealed, leading to the exterior of water control housing (2). At the same time, shaft (4) is also the center of rotation for a second lever (5) which is likewise rigidly connected to it.

  • Fixing a tool in position
    Patent number: 5875696
    Abstract: A tool fixing device for machine tools has a tool holder with a tool holder body for bearing the tool, and a tool carrier with a tool station. The tool station has a support surface and a receiver for receiving a shaft from the tool holder. An aligning device operative between the tool holder body and the tool carrier is used to position the tool holder body relative to the tool carrier, such that the tool holders in the respective tool station of the tool carrier need not be readjusted each time they are inserted. The aligning device has two aligning elements, one on the tool carrier, and the other on the tool holder body. When the shaft from the tool holder is clamped in the receiver on the tool station, the aligning elements fix the tool carrier so as to be aligned in a single position using form-fitting elements which engage in one another without clearance.

  • Housing for receiving individual components of a heating or cooling installation
    Patent number: 5875821
    Abstract: A housing for receiving individual components of a heating or cooling installation is formed of at least two shells of thermally insulating plastic which enclose the components between themselves. The shells are provided at their respective facing edges with a rabbet connection formed of a rabbet strip and a groove strip corresponding thereto in shape and dimensions. The flank of the groove strip of the bottom shell which cooperates with the rabbet strip is divided into an upper partial surface inclined relative to the rabbet strip at an angle .alpha. to the normal line and a lower partial surface which is inclined at an angle .beta. to the normal line. The angles .alpha. and .beta. have opposite rotational directions. The rabbet strip of the top shell has surfaces corresponding to the surfaces of the groove strip so as to substantially facilitate closing and opening of the housing.

  • Method for producing tomosynthesis exposures employing a reference object formed by a region of the examination subject
    Patent number: 5878104
    Abstract: In a method for producing a tomosynthesis exposure a reference object is used which is formed by a region of the examination subject. It is thus possible to determine the distance of the beam transmitter to the beam receiver and to the examination subject, the irradiation angle, and the direction of irradiation, on the basis of the signals that can be derived from the beam receiver during the transillumination of the reference object, without the reference object causing any disturbance in the region of the subject of examination.
