Filed: 1982-09-23
Abstract: A polymer granulate whose particles consist of a core component and a coating component can be prepared by mixing a granular polymer with a pulverulent coating agent. The core component is made of a water-soluble polymer, in particular a polyvinyl alcohol. The coating component is a water-soluble or water-insoluble substance which is applied to the water-moistened particles of the core component. The particles of the polymer granulate have diameters within the range from 0.6 to 6 mm. The granulate has particularly good freeflowing properties; it is especially suitable for preparing adhesives.

Title: Electric force sensor
Inventor: BAUMANN EBERHARD DR
IPC: G01L1/22
Filed: 1982-10-04
Abstract: The invention relates to an electric force sensor and appertains to the field of electrical measurement of forces with measuring transducers which work with wire strain gauges. By slight modifications to the deformation body, which is of the compression-body type, the invention achieves the object of specifying such a deformation body which avoids the known disadvantages of the compression-body deformation type. Here, the production costs for this deformation body are to be reduced compared with bending, shearing-stress and torsion bodies. The essence of the invention consists in the fact that a zone is formed in the deformation-body sections between the active part carrying the wire strain gauges and the outer force-inducing surfaces, which zone prevents transverse extensions, which preferably originate from friction forces at the force-inducing surfaces, from being transmitted to the active part. In addition, the active zone is to be designed in such a way that it concentrates the useful stresses in the body, which act in the direction of the external force. The fields of application relate to the technology of electrical force measurement. Figure 1 illustrates the mode of operation. <IMAGE>

Patent DE-3243582-A1 (DE)
Inventor: HUMMEL PETER
IPC: B41F31/14
Filed: 1982-11-25
Abstract: A mechanism for axially reciprocating at least one of the distributing rollers of a printing press. A rocker having an elongated slot therein is mounted on a first pivot and oscillated thereabout by means of a link eccentrically connected to the press drive shaft. An oscillating lever is pivotally connected to the press frame for movement about a second pivot and includes a sliding block captively held in the elongated slot of the rocker. The oscillating lever is operatively connected to at least one of the distributing rollers so as to axially reciprocate the roller in response to the oscillation of the lever. The location of the first pivot is adjustable with respect to the press frame so as to change the orientation of the elongated slot in the rocker and, thus, vary the magnitude of travel of the oscillating lever which reciprocates the distributing roller. For such purpose, the first pivot is secured in one arm of a two-armed lever, the lever being pivotally connected to the frame. The second arm of the lever is secured to a traveling nut which is threaded on a shaft mounted for rotational movement with respect to the frame. Either a manually turnable knob or an electric motor is connected to the shaft so as to rotate the same, resulting in a rotation of the two-armed lever about its pivot to change the position of the first pivot held in the first arm of the lever.

Title: Method and circuit arrangement for limiting the intermediate circuit voltage of a pulse inverter supplying an AC motor
Inventor: SIEVERT BERND DIPL ING
IPC: H02P23/06
Filed: 1983-07-22
Abstract: The subject-matter of the invention is a method and a circuit arrangement for limiting the voltage of a DC voltage intermediate circuit, which is supplied via a rectifier from an AC network, of a pulse inverter which supplies an AC motor with a variable pulse frequency. The pulse inverter has freewheeling diodes for feedback into the intermediate circuit, and the desired value of the pulse frequency in the generator mode is controlled as a function of the actual value of the intermediate circuit voltage. In the case of a method and a circuit arrangement of the generic type, it is now intended to specify control of the desired value of the pulse frequency in the generator mode of the AC motor as a function of the actual value of the intermediate circuit voltage such that a predetermined increase in the intermediate circuit voltage cannot be exceeded as a result of the energy feedback into the intermediate circuit. For this purpose, the peak value of the network voltage is detected and subtracted from the instantaneous value of the intermediate circuit voltage, an analogue continuous controller taking over the control of the pulse frequency when the subtraction difference is positive in order to control the intermediate circuit voltage in the generator mode at a predetermined desired value.

Patent DE-3410165-A1 (DE)
Title: Arrangement for stabilising the inclination of electro-optical range finders
Inventor: FEIST WIELAND DR
IPC: G01C3/02
Filed: 1984-03-20
Abstract: The invention relates to an arrangement for stabilising the inclination of electro-optical range finders for angle and distance measurement. The arrangement is designed in such a manner that the visual aiming axis and the electro-optical axis of an electro-optical range finder are stabilised jointly and simultaneously at one measuring point. This is achieved by one inclination-stabilising, reflecting and imaging component being provided for all beam paths of the telescope systems of an electro-optical range finder. The invention makes it possible to save operating time in the measuring process during the electro-optical range finding, since the measuring instrument no longer needs to be set up above or below a measuring site when measuring relatively large heights and depths, but measurements can be taken from an externally situated point. When an electro-optical tachymeter is used for range finding, the modules of automatic inclination stabilisation and the automatic angle measuring system are omitted because the observer no longer needs to adjust the stabilised inclination at the vertical circuit before each measurement.
