摘要:
A vector analyzer which serves for determining defining quantities of a planar vector in which the output of a digital counter is fed, via sine and cosine function generators, to a vector rotator addressed by the component voltages of an input vector and made to follow the value of the phase angle of the input vector by means of a three point control in order to make the output of the digital overflow counter follow the phase angle of an input vector by means of a control loop; the counter content is reset to zero without problem if the value 360.degree. of the phase angle is exceeded. The invention can be used particularly for field orientation control of rotating field machines.

The invention relates to a method for creating a robot model (17) of an industrial robot (1) which has a robotic arm (2) having a plurality of successive limbs (3-8) which are adjustable by means of drives (11-16) via transmissions (5) in relation to axes (A1-A2), controlled by a control device (10) of the industrial robot (1). According to the invention, the robotic arm (2) is moved in a plurality of poses. At least one of the limbs (4) is moved in the same first movement direction (18) by means of the drive (11) thereof at least upon approaching the individual poses. In order to obtain the robot model (17), the robotic arm (2) is measured at each of the poses thereof.

A method according to the invention for operating a manipulator, in particular a robot (1), includes the following steps: determining (S10) parameters (c′, c″) of an exactly positioned manipulator model (M) with various nominal loads (m′, m″); specifying parameters (c) of the manipulator model on the basis of which the manipulator is operated, depending on a payload (m) of the manipulator (S20); and operating the manipulator on the basis of the manipulator model (S30, S40).
摘要:
In one embodiment of the present invention, a process that uses a first processor is provided. The process includes the operation of blocking by the first processor of completion by a second processor of a configuration cycle. The process also includes the operation of selecting by the first processor of one procedure from a plurality of procedures that are associated with respective types of circuitry that may be used to permit the first processor to control a device. The one procedure is associated with one of the respective types of circuitry that is actually available to be used by the first processor.

摘要:
The present invention relates to molded articles of an open-cell structure, containing a copolymer which is comprised of copolymerized, fluorinated olefin, copolymerized vinyl acetate and optionally copolymerized olefin, the acetate groups of the copolymer being optionally saponified into OH groups. The molded articles possess an inherent latent structural convertibility and have effective pores of a diameter in the range from 0.002 to 10 .mu.m. The invention further includes processes for the preparation of the specified molded articles and processes for converting their structure. The invention also relates to several uses of molded articles according to the invention.
摘要:
An apparatus for stuffing a shirred tubular casing with a fluid material such as a sausage composition or pieces of ham comprising a stuffing horn having an aperture through which the fluid material is forced under pressure into the casing, a device located on the periphery of the stuffing horn and within the interior of the casing for smoothing and expanding the casing, the device comprising at least two disk-shaped planar bodies, at least one of which is rotatable in a plane parallel to and/or shiftable perpendicular to the longitudinal axis of the stuffing horn, the outer circumference of each planar body being smaller than the inner circumference of the tubular casing, whereby the projection of the cross-sectional surfaces of the planar bodies in the direction of the longitudinal axis upon rotating or shifting of the bodies results in a total surface having a greater circumference than the inner circumference of the tubular casing.
摘要:
A membrane unit and apparatus for removing toxic metabolites and metabolites normally present in urine from blood is disclosed. The unit comprises an arrangement of at least one permselective membrane and a fluid-absorbing and/or fluid-draining carrier containing at least one adsorbent. The apparatus comprises at least one membrane unit which is connected to inlet and outlet means for transporting blood to and from the unit.
