    摘要: An apparatus for measuring tension of piston rings includes a cylindrical support fixture having a circumferential groove formed therearound for receiving and holding a piston ring. A rigid base supports a plurality of components of the apparatus. A strong, thin band, formed from a material sufficiently strong to withstand repeated applications of pulling force thereto, is mounted to the base, and is held between two clamps. The band has a loop formed therein, for receiving the support fixture with a piston ring mounted therein. The apparatus also includes reciprocally movable structure for tightening the band around the support fixture, such as a slidably movable clamp assembly at one end of the band. The apparatus further includes mechanism for measuring tension on the band, and fluid activatable mechanism for vertically reciprocating a portion of the support fixture. In a preferred embodiment, the reciprocating mechanism is pneumatically activatable, such as by compressed air.

    摘要: 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.

    摘要: 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. Each local office includes access means for accessing the assigned time slots of the time division multiplexed signals on the transmission line pair, and control means responsive to the interoffice signal sent from the center office for controlling the access means, whereby when a communication is made between two offices belonging to the loop, the processing means of the central office assigns time slot to said offices between which communication is made for causing the access means of the local offices to operate under control of the control means so as to form with the assigned time slots two route channels, one passing through a specific point on a transmission path provided by the transmission line pair, while the other not passing through the specific point thereby performing interoffice communications through at least one of the route channels under the control of either one of the processing means of the central office and the control means of the local office.

    摘要: 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.

    摘要: 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.
