Abstract: A telescoping, U-shaped straight through, primary flow invert form may be lenghtened or shortened to meet the diameter of the cylindrical manhole and is mounted at opposite ends to the aligned main flow inlet and outlet pipes of the manhole. Longitudinally projecting bottom and opposed side invert tabs located at the ends of the straight through invert form contact the insides of the inlet and outlet pipes, respectively, to center the form. Slide guides, each carrying a retainer tab, adjust the retaining tabs longitudinally to position them within respective pipes at respective ends of the form for preventing lifting of the invert form during concrete pouring within the manhole. An angularly adjustable, intersecting side flow invert form projects from another pipe opening to the manhole at some angle to the straight through form and includes interlocking, axially slidable, opposed section halves.

Abstract: A tractor vehicle has a driving station including a driver's seat and steering console which is mounted on a base for swivelling movement about a vertical axis through 180.degree. between a tractor configuration and a pushing power unit configuration. In the latter configuration the driving station is supported on a higher tractor cab floor level to enable the driver to see over equipment being pushed. The driving station has a support which is connected to the tractor cab floor by at least one parallelogram linkage and weight compensating springs which lift the support off the cab floor.

Abstract: Each key of the pedalboard is supported and guided for pivotal movement in a vertical plane by a steel strip secured to the underside of each key adjacent the midportion thereof. The rear end of each key is operatively connected to a transversely extending rear frame for horizontal reciprocating movement perpendicular to the rear frame and the forward end of each key is disposed between transversely extending upper and lower and front frame members for limited vertical movement therebetween. The forward end of each steel strip is secured to the lower front frame member to normally bias the forward end of each key into engagement with the upper front frame member.

Abstract: The present invention relates to novel treating agents for treating waste water containing dyes and/or other organic substances, a process for treating said waste water by using said treating agent, and an equipment for the same.The treating agent is prepared by mixing component A comprising a water-insoluble calcium salts and component B consisting mainly of aluminum hydroxide, aluminum oxide or a mixture thereof at a molar ratio of 3:1 to 1:3 and heating said mixture of components A and B as such or after granulation at a temperature between 100.degree. C. and 450.degree. C.The treating agent thus obtained has excellent adsorption and oxidative ability and is capable of easily clarifying waste water discharged from fiber processing plants that contains a variety of dyes and other organic substances, for example, sizing agents such as starch, polyvinyl alcohol and C.M.C.

Abstract: The method for processing a mixture of air and rare gases consisting especially of xenon and krypton which are at least partially radioactive and especially for processing gaseous effluents arising from the reprocessing of irradiated fuels comprises a step involving concentration of the rare gases in solution in liquid argon by cryogenic distillation of the light gases and mainly nitrogen from the liquefied mixture.

Abstract: Porous film materials composed of polytetrafluoroethylene having an asymmetric structure are produced by stretching the film using a pair of revolving rolls which are heated to a temperature lower than the melting point of the film. Stretching is produced by revolving the two rolls at different speeds which also tends to produce a compressive force in the thickness of the film. The rolls are heated to different temperatures to produce a temperature difference of preferably 50.degree. C. or more. The combination of the compressive force and the temperature gradient in the thickness of the film is believed to produce the asymmetric structure in the resulting porous film materials which are characterized by a fiber structure in the surface which is different from that in the back.

Abstract: A faucet has a sealing member clamped at its periphery and overlying an orifice through which fluid is to flow. Pressure applying means maintains the sealing member in sealing engagement with the wall defining the orifice. Upon removal of the pressure applying means the sealing member moves away from the orifice to permit flow.The pressure applying means is located in a valve body which is screwed into the faucet housing and acts to change the periphery of the sealing member. The valve body may be removed by removing the handle and engaging a pair of projections within the handle with a pair of ears on the valve body. The sealing member is thus unclamped and easily removed.
