    Abstract: A linear guide includes rolling bodies that are inserted into mutually corresponding grooves of mutually guided parts. The guide surfaces for the rolling bodies are partially formed by plane surfaces of rotatable beveled round rods that are positioned in the grooves. The linear guide is constructed as a double guide on both sides with respectively two spaced-apart guide grooves on mutually opposed sides of the mutually guided parts. Because the guide surfaces are partially formed by the plane surfaces of the rotatable beveled round rods, wedge angles between the mutually guided parts are compensated. Manufacturing technical requirements regarding the matching of the distances of the guide grooves to each other are thereby greatly reduced.

    Abstract: A drive system for the conversion of a rotary motion into a linear motion contains a belt drive similar to a block and pulley system, and a system of a rack and pinion that is driven synchronously with the belt drive. The pinion and the rack are adjusted with respect to each other such that the teeth of the pinion engage with relatively large play in the rack. When driving under normal load, the drive takes place without loading of the rack and pinion system by the belt drive, so that the reversal backlash and the play of the rack and pinion system remain without effect on the displacement motion. When an overloading of the moving part and a corresponding stretching of the drive belt occur, the tooth flanks of the pinion and of the rack are supported against each other and in this manner prevent tearing or overloading of the drive belt. The drive system has a high reproducibility and a small reversal back-lash, and is particularly applicable for the drive of the focusing motion in microscopes with automatic repositioning by means of a drive motor.

    Abstract: A process for the continuous manufacture of sheeting from thermoplastic synthetic resins includes the steps of applying thermoplastic synthetic resin, in the form of particles, such as shreds, crumbs, cuttings, pieces, chips, or the like, continuously as a sheet-like layer of raw material to a moving support; passing the raw material layer through a heating zone to thereby preheat the material layer to a temperature approximately in the range from 100.degree. to 140.degree. C.; pressing the preheated material layer continuously over its full area during travel through a treatment zone so that, in a first phase, the raw material layer is compacted and welded under the effect of a pressure of from about 10 to 60 kp/cm.sup.2 and at the same time the material layer is heated to a temperature in the range from about 160.degree. to 220.degree. C; and, in a second, directly following phase, while maintaining said pressure, cooling the material layer and simultaneously pressing the layer to the thickness dimension predetermined by the amount of raw material layer applied to the moving support.
