A heat wave shielding lamination consisting of at least two In2O3 shield layers containing different amounts of Sn is provided on the surface of a glass substrate to provide shielding against heat waves without causing heat wave pollution in the surrounding environment. The amount of tin contained in the respective layers increases with increasing proximity to the substrate. The heat wave shieldin...

PURPOSE:To obtain the titled film good in mechanical strength and transparency, by adjusting the water content of a water-containing solidified film on an acrylonitrile type polymer, stretching longitudinally the film by rolls of a specified surface temperature, and then strentching laterally the film by a tenter under specified conditions with the water content of the film adjusted lower than in ...

PURPOSE:To obtain adequately distributed light and to provide excellent visibility by forming many prism-like columnar lenses which are formed to have the wall thickness increasing downward in such a way as to extend horizontally. CONSTITUTION:A light source 3 is fitted nearly in the focal position of a reflecting mirror 2, and an inner lens 5 in a front opening 4. A prism part 6 is formed nearly ...

The buckets of a turbine wheel are formed as a series of equally spaced, overlapping U-shaped passages in the rim of a wheel blank. In the machining operation, an island is left as the inner segment of the curved portion of the U and this is used in combination with labyrinth seals to provide a fluid seal between the inlet and the outlet portion of each bucket.

PURPOSE:To control the ignition timing of all cylinders at an optimum condition by setting a knocking detection level for each cylinder and controlling the ignition timing for each cylinder in response to detected knocking signals. CONSTITUTION:A knocking sensor 7 converts engine vibrations into electric signals, and the signals of the sensor 7 are processed by a portion comprised of the band pass...

Mixtures of finely divided solids and gases are subjected to a thermal treatment by feeding the optionally heated gas tangentially into the lower section of an axially symmetrical vessel, adding the solid to the gas at the latest in the vessel, heating or cooling the mixture of solid and gas in the vessel through the wall thereof and discharging the mixture in the upper section of the vessel. The ...

A method of insulating tubing comprising the steps of providing the tubing with a jacket of insulating material in web form, fixing the jacket with regard to its described diametrical dimensions, e.g. with a fixing casing, enclosing the jacketed tubing in a continuous tubular outer casing, e.g. by applying relative movement in the longitudinal direction thereof, and subsequently breaking the fixed...

Fluid streams containing hydrogen sulfide from a steam turbine or from a sour gas stream are contacted with an aqueous solution of a polyvalent metal chelate and an oxidizing agent whereby the hydrogen sulfide is converted to free sulfur and then to soluble sulfur compounds. The metal chelate is reduced to a lower oxidation state metal chelate and reduced metal chelate is subsequently oxidized wit...

A method of forming a casing for a booster wherein the casing is preliminarily preformed with a peripheral sleeve portion and a flat base portion connected by a web. The preformed casing is placed in a frame and the peripheral sleeve portion held in substantially fixed position to maintain a required transverse dimension. A reinforcing member is positioned adjacent the flat base and an axial force...

A radiation pyrometer for a gas-turbine engine has a sapphire lens that focusses radiation from the turbine blades onto the end of a fibre-optic cable. The front, exposed surface of the lens has a vapor deposited layer comprising a mixture of platinum and aluminum oxide which acts as a catalyst to promote oxidation of soot to a gaseous form and thereby reduce contamination of the lens.

In spun fleeces of thermoplastics in which the filaments are in approximately random arrangement, which fleeces have been strengthened by needle-punching and which have a higher tensile strength in one direction than in the direction at right angles thereto, the said tensile strengths are approximated to one another by stretching the fleece by 20 to 200% of the original length, in the direction of...
