Abstract: An automatic line spacing device which can be advantageously incorporated in typewriters, especially of the type which has no constantly rotating power shaft. A feed pawl is mounted on a rockable member and cooperates with a ratchet to angularly rotate a typewriter type platen. The rockable member is constantly coupled to a bidirectional electric motor which is first energized sufficiently to angularly rotate the rockable member from its home position to a rotated limit position defined by a fixed positive stop element for effecting a line spacing operation and then secondly energized sufficiently to rotate the rockable member back to its home position as defined by another stop element. A cam adjusts the angle during which the feed pawl engages the ratchet so as to effect different line spacing increments.

Abstract: A continuous process for thermally cracking a heavy hydrocarbon oil, including heat-treating the heavy hydrocarbon oil in a first thermal cracking zone for obtaining a first cracked product, and introducing the first cracked product into a second thermal cracking zone where it is thermally cracked by direct contact with a gaseous heat transfer medium to form distillable cracked components and a mesophase-containing pitch. The liquid phase in the second thermal cracking zone, including the mesophase-containing pitch, is withdrawn therefrom and separated into a mesophase-rich pitch and a matrix pitch having a low concentration of mesophase. The matrix pitch is recycled to the second thermal cracking zone. The distillable cracked components are stripped from the liquid phase in the second thermal cracking zone with the heat transfer medium, and the resulting gas phase is discharged overhead therefrom and then separated into a light fraction and a heavy fraction.

Abstract: An operating part, essential to the starting-up or use of a power-operated device (1), e.g. driven by an engine or a pressure-medium, is made in the form of a tool-carrier (4). Permanently attached to the tool-carrier (4) is at least one tool, preferably a set of tools, specifically intended for the maintenance, cleaning, or the like of the device. However, the operating part constituting the tool-carrier (4) is arranged detachably upon a functional element (2,3) of the device (1). It is therefore scarcely possible for the tool to be lost after it has been used, since the device (1) only becomes serviceable again (i.e. may be driven or guided by the operator) after the operating part of the device (1) which has been removed, and which constitutes the tool-carrier (4), has been replaced.

Abstract: Method for diagnosis of the presence of atherosclerosis plaques. The method comprises injection of a hematoporphyrin which is selectively absorbed by atheromotous plaques.

Abstract: The invention relates to a glass lathe for producing preforms which may be drawn into energy transmitting fibers. The apparatus includes a head stock and a tail stock for rotatably holding a starter tube and the preform as it is built from the starter tube. The tail stock is movable along the lathe bed with respect to the head stock so that a preform may be drawn down to approximately the diameter of the starter tube. A carriage is provided on the lathe bed which carries at least one burner for melting a particulate quartz feed and depositing it onto the rotating surface of the starter tube. A slide member mounted on the carriage supports a container for catching particulate quartz which does not adhere to the tube and a coolant reservoir adapted to produce a fountain for contacting and cooling the tube downstream of the burner.

Abstract: A construction element for constructing a supporting floor or the like consists of a slab made of reinforced concrete. The side walls of the slab are provided with protection profiles connected with each other. Two series of aligned, alternating projections and complementary recesses are lying above each other on each side wall of the slab, wherein the projections of one of the series are staggered with respect to the projections of the other series in such a manner that the recesses of one of the series lie above respectively below the projections of the other series. The projections of the lower series lie at a distance from the lower surface of the slab. As the construction elements forming a supporting floor are connected with each other by the interlocking projections and recesses of the adjacent side walls, the load of a construction element is distributed over the adjacent construction elements so that each construction element can take up a very high load.
