Date Nov. 27, 1980.During the winding of coils with a non-circular shape the wire length necessary varies periodically for a trouble-free winding per unit of time. At a high winding rotational speed and unsatisfactory side ratios relative to the coil being wound, the periodic change in the required wire length is so large that with known wire brakes there is no adequate winding quality with a concurrent protective handling of the wire. These opposite goals are reached through the invention with the aid of a controllable wire brake which essentially consists of a plurality of brake strands wound about the wire in a single layer.

Abstract: A foamed plastic and a method for its production are described. Tne foamed plastic has cavities which consist of open cells or pores. In at least a portion of the cavities, particles of water-insoluble hydrophilic polymer are homogeneously distributed, the particles being swellable to a gel in water. Examples of such polymer particles are granules of cross-linked dextran. The polymer particles are incorporated in the foamed plastic by being suspended in a liquid impregnating agent, such as ethanol-chloroform which is of substantially the same density as the polymer particles. A water-soluble binder, such as polyvinyl pyrrolidone, is also dissolved in the impregnating agent, and suitably also a plasticizing and surface active agent, such as a poloxamer. The foamed plastic is impregnated with the liquid suspension, whereafter the impregnating liquid is removed by drying. The polymer particles are anchored to the dried foamed plastic by means of the binder, whereas the polymer particles, on use of the foamed plastic product for, for example, treating a running sore, swell to form a gel such that they fill out the cavities of the foamed plastic and are retained because of steric hindrance. The foamed plastic product is int.al. usable as a bandage and/or for plugging to drain exudate from injured skin surfaces, such as running sores, and in the treatment of incontinence. Also non-clinical fields of use, such as the use of gel iodophore-provided foamed plastic for water purification, are included in the invention.

Abstract: In the production of a tubular extruded section of thermoplastic material, the actual length of an extruded section at the end of the extrusion operation may be smaller or greater than the length of the extruded section which passed through the discharge orifice of the extrusion head during extrusion. If the wall thickness of the extruded section is varied during extrusion in accordance with a given program, inaccuracies in regard to distribution of the wall thickness over the length of the extruded section can be reduced by detecting the length of the extruded section which passes through the discharge orifice, and controlling the means for producing the programmed variation in wall thickness, in dependence on that discharge length. The same effect can be achieved by controlling the means for producing the programmed variation in wall thickness, in dependence on discharge speed and time. A higher degree of accuracy can be achieved by measuring the discharge length or discharge speed on the one hand and on the other hand the respective associated effective length of the extruded section, or the speed of movement of the free end of the extruded section, comparing those two detected values, and producing corrective variations in wall thickness in dependence on the result of the comparison operation.

An annulus gear (38) is fixedly disposed, such as for example by the surrounding transmission housing, and has internal gear teeth (40) which are engageable with the first set of external gear teeth (34) of the circular gear (28) upon overlap therebetween. An eccentric (26) is fixedly mounted on the transmission spindle shaft (24) and freely mounts the circular gear (28) thereon for maintaining the circular gear (28) and the annulus gear (38) in overlapping relationship, thus engaging the respective gear teeth thereof. By means thereof, the circular gear (28) traces a hypocycloid at reduced rotational speed within the annulus gear (38) in a second rotational direction opposite to the first rotational direction of the transmission spindle shaft (24). A rotatable drive hub (42) having internally disposed teeth (44) is disposed to surround a portion of the circular gear (28) and to receive the reduced rotational speed thereof by means of the overlap between the circular gear (28) and the drive hub (42). An output shaft (46) is connected to the drive hub (42) for receiving and transmitting the reduced rotational speed output. The various gears may preferably be made of a non-machined material, such as forged, cast, molded or extruded metal, plastic or other relatively rigid and durable material.
