Title: Liq reflectometer used as vessel filling detector - uses total reflection of light rays within a paraboloid or ellipsoid hollow body
IPC: G01F23/292
Filed: 1974-10-25
Abstract: The equipment may be used for checking the filling of a vessel, typically an oil tank, with liquid, which fills an outer housing (9), within which is an inner body (1) of paraboloid or ellipsoidal form, which is normally filled with a gas such as air.

Title: Pile yarn texturising process - uses a heated eddy airstream to give a double twist to continuous synthetic yarn
IPC: D02G1/02
Filed: 1975-03-27
Abstract: The process to give a bulked and texturised effect to continuous thermoplastic filaments, with false-twisting, uses a high-speed airstream heated to 155-300 degrees C directed at the oriented yarn, after it passes between toothed wheels, to give it a pneumatic twisting effect, to be fixed and cooled to be bulked by passing through a venturi tube with a further 155-300 degrees C high-speed airstream where the yarn entry speed is higher than its outlet rate. The process gives a double-crimped yarn of high bulked character for use in tufted and other pile carpetings.

Title: Hot rolled ductile steel sheet - contg. a limited amt. of carbon and manganese, and sulphide and silicate inclusions in the form of short needles
Inventor: TAKECHI HIROSHI
IPC: C22C38/60
Filed: 1975-06-20
Abstract: The steel sheet, which has good cold working properties, contains 0.03-0.30% C (0.05-0.30%) and 0.15-2.0% Mn (0.5-2.0%) as main addns., and needle-like sulphide and/or silicate inclusions, the needles having an average length of 100 (80) mu. The ductile sheet is produced from a cast bar (batch or continuously cast) which is hot rolled at a final temp. of 800-1100 degrees C, and with a final rolling speed of at least 1100 m/min. The average rate of cooling from the final temp. of rolling to the temp. of coiling is over 30 degrees C/sec. The cold working properties and ductility of the steel are improved by controlling the sulphide and silicate inclusions in a simple manner in that the rolling conditions are controlled, i.e., final rolling temp., speed of final rolling and cooling rate, and it is not necessary as in the conventional method to add modifying elements or further deoxidation agents.

Title: Automatic control for process drier esp. of grain - uses series of time control circuits connected in parallel overriding single control according to temp.
IPC: F26B25/22
Filed: 1975-09-12
Abstract: A device for automatic control of a process drier, in partic. for grain, is designed to produce control efficiency comparable to conventional methods whilst being less complicated. The drier is controlled to produce corn with a moisture content within defined limits from corn input with moisture content varying according to ripeness, temp., and ambient humidity. The grain moisture content is measured with a temp, sensor whose output is used to control a discharge device which releases the grain from the drier. A time control device regulating the operating cycle of the discharge mechanism is controlled by a series of time control circuits connected in parallel which override the single control device according to the measured temp.
