Abstract: Briquettes made from bituminous or sub-bituminous coal or peat are produced by grinding the coal, mixing it with a binder and compacting the mixture. They are then carbonized in a continuous process in a shaft oven. The coal may be predried and the finished briquettes may be preheated, with a subsequent drying and hardening. The carbonization is effected in two stages in an indirectly heated shaft oven, with the evolved gas being taken off about at the mid-height of the oven shaft, processed, and used for heating in the second, high-temperature stage. The flue gases from this high-temperature stage are used for heating in the first stage and for preheating. The second or high-temperature stage is followed by a cooling stage where the gases evolved in the second stage, and mainly comprising hydrogen are used and circulated. The evolved gas in excess is continuously removed from the cooling circuit.

Abstract: Sewing machine with a control for the movement of a workholder. For the formation of edge parallel seams when sewing on labels with seam sections extending parallel to the movement axes of a cross slide system carrying the work holder, there are arranged at uniform distance from the stitch hole four transmitted light sensors, of which always only the one which can recognize the crosswise extending following edge of a seam section is switchable into readiness for operation. After a signal has been given by a sensor, the respective drive motor of the cross slide system is controlled by means of a microcomputer in such a way that the respective seam section ends exactly in the intended corner. Because of the work related feed control, a sewing program is not needed. Besides, the control automatically adapts itself to different label dimensions.

Abstract: A tool for measuring rolled-up material comprises a housing with a measuring thread spool rotatably mounted in the housing, having a supply of measuring thread thereon, which is delivered out of the housing through a rotatable delivery tube which is angled to one side so that the tip of the tube may be passed around the material to be measured after the measuring material is anchored to the end of the material being measured. The measuring thread is advantageously passed over the thread spool which may be cylindrical and of uniform diameter or may vary in diameter from one side to the other. The thread spool is part of a counter which records the length of measuring thread that is fed out, preferably in feet and inches when the thread spool is made in the form of a cone measuring thread is guided on each side of the spool so that it passes over selective thicknesses of the spool and, thus, the feed-out speed is varied and so is the counting in dependence on how the thread is guided over the spool.
