Abstract: Disclosed is a novel carcinostatic composition comprising 4,6-0-benzylidene-D-glucopyranose as the active ingredient. This active ingredient exerts a very high carcinostatic activity according to a specific carcinostatic mechanism quite different from that of conventional carcinostatic chemotherapeutic agents. The active ingredient is very low in toxicity and is highly stable and water-soluble. This composition is effective against selected malignant conditions which are carcinoma of the colon, cancer of the stomach, cancer of the tongue, peritonitis carcinomatosa, cancer of the liver and malignancies induced by SV.sub.40 virus.

Abstract: A process is disclosed for making a casting nozzle wherein gas can be blown out through the outlet of the nozzle to prevent the sticking of nonmetallic impurities to the nozzle during use. Reticulate organic filaments in the form, e.g., of a net are applied around a preformed inner cylindrical refractory body having a pouring hole therein. An outer cylinder body is then formed around the inner cylinder body including the organic filaments. The entire body is then fired, whereby the organic filaments carbonize and evaporate, leaving a network of gas-permeable reticulate holes in the body. An outlet is drilled or cut in the fired body through the gas-permeable holes to the pouring holes. Accordingly, when the nozzle is in use, a blowing gas can be provided through the reticulate holes to the nozzle outlet to prevent the sticking of nonmetallic impurities.

Abstract: A casting nozzle designed such that the sticking of nonmetallic impurities to the outlet of the nozzle is prevented by blowing out a gas. The casting nozzle comprises a nozzle proper, an annular hollow chamber for gas blowing formed in the axial direction of the nozzle proper, and annularly arranged reticulate small holes for gas blowing communicating with the annular hollow chamber, the small holes opening at the outlet of the nozzle. The reticulate small holes are formed when organic filaments wound round a portion of the inside wall of the nozzle proper carbonize, volatilize, or shrink upon heating.

Abstract: A device for tracking a movable body along a linear path parallel to a plane includes a linear motor for driving the body along the linear path. The body is mounted, as by rollers, for movement along a guide, such as a pair of parallel guide rails, supported on a base which also supports the motor. To enhance stability of the body during tracking movement, the rollers or other mounts for the body are urged against the guide by the magnetic action of a flux which is separate from the principal flux used to generate thrust for the linear motor and which provides an attractive force against preferably a pair of members, such as steel plates, of high magnetic permeability fixed to the movable body.

Abstract: A time division multiplex communication circuit is constituted by a set of loop shaped transmission line pairs which transmits time division multiplexed signals via a clockwise transmission line and a counterclockwise transmission line, a center office connected to starting and terminal ends of the transmission line pair, and a plurality of local offices located at intermediate points of the transmission line pair. The center office includes a device connected to the starting and terminal ends of the transmission line pair for transmitting and receiving signals therewith, and a processing means for assigning time slots of time division multiplexed channels of the transmission line pairs to signals to be sent to the transmission line pairs and for sending an interoffice signal regarding the assignment of the time slots to the local offices.

Abstract: Fuel oil containing sodium salt, potassium salt and solid matters is purified by separating the fuel oil into fuel oil and sludges by a centrifugal separating means, thereby removing the sludges from the fuel oil, and mixing the fuel oil freed from the sludges with water, and separating the resulting liquid mixture into fuel oil and water. Removal of the salts and the solid matters from the fuel oil can be attained at the same time very effectively with a reduced frequency of cleaning a filter or by omitting the use of the filter, with or without using an emulsion breaker.

Abstract: A process is described for cracking a heavy hydrocarbon to form a light oil and for producing hydrogen by the use of a catalyst containing at least 30 wt % Fe which comprises a first step wherein steam and heavy hydrocarbon are simultaneously contacted with the catalyst in a reduced state to produce hydrogen, cracked gases, and a cracked light oil, to oxidize the reduced-state catalyst, and to deposit coke on the catalyst; and a second step wherein the oxidized-state catalyst on which said coke is deposited is contacted with an oxygen-containing gas insufficient for achieving complete combustion of the coke, to thereby partially combust the coke and regenerate the catalyst to a reduced state.
