Title: Indirect determn. of steel smelting temp - by continuous monitoring of melt plus crucible wt. esp. for use in oxygen blast steel prodn
IPC: G01G3/14
Filed: 1973-10-19
Abstract: Crucible is mounted on trunnions in bearing bushes whose flanges are supported on strain gauge type load cells connected in bridge circuits to continuously produce electrical analogue signals corresp. to wt. This measured analogue is pen-recorded during the O-feed phase and simultaneously differentiated to indicate rate of change of wt. with time on a second pen recorder. The two records are used, in conjuction with a mathematical model or calibration curve which covers the point at which first phase of decarbonisation undergoes its transition into the second phase, to indirectly determine the temp. of that transition and during the subsequent second phase of decarbonisation. The oxygen blast, whose feed rate is esp. constant, is from a lance or from valves in the crucible base. The plant has long life as immersed temp. sensor methods are not involved.

Title: Optical technique for surface roughness measurement - using two plane coherent light waves and interference effects
Inventor: PERRIN J C
IPC: G01B11/30
Filed: 1975-02-07
Abstract: Method of measuring surface roughness involves luminating the surface (s) simultaneously with two plane coherent waves (1, 2) which are angularly separated ( THETA) from each other in the same plane of incidence. The surface is observed simulataneously from two directions (3, 4) in the same plane of incidence using an optical (I2) system which produces interference. The phase of one of the beams (1) is modulated and the global modulated illumination is measured in the interference plane and converted into a modulated electrical signal. The modulated depth determines the surface roughness.

Title: Chain drive for use in IC engine - has tooth contact faces machined to cause radial movement of chain rollers for wear take-up
Inventor: SOUBRE RENE
IPC: F16H55/30
Filed: 1975-09-26
Abstract: A chain driven by a toothed pinion transmits power to a toothed gear wheel. The teeth of the pinion have the driving side face machined at an angle to the radius through the base of the tooth recess sufficiently large to ensure that the reaction between the tooth and the chain roller has a component tending to push the roller radially out of the tooth space. The teeth of the wheel have the driven side face machined at a second angle to the radius sufficiently large to have a similar effect. As the chain rollers wear, they move radially outwards on both pinion and wheel and thus automatically take up the slack resulting from wear.

Patent FR-2307496-A1 (FR)
IPC: A47C7/40
Filed: 1976-04-14
Abstract: A portable back rest, composed of one planar sheet of material adapted particularly, but not exclusively, for use on stadium, or the like, bleacher or plank seats which are not provided with backs. The back rest is of unitary one piece construction and comprises a sheet of material in generally planar configuration which may be stamped or molded into the proper flat configuration for ease of transport and storage. The material from which the back rest is stamped or molded, is flexible so that it may be flexed from its flat transport and storage condition to its operative condition for combination with a bleacher seat. The one piece planar sheet of material from which the back rest is made, has an inherent "memory," or self adjusting characteristic, which urges it at all times to assume its flat transport and storage condition. The back rest is provided with means integral therewith for releasably clamping or locking the back rest in operative position on a bleacher seat. The "memory" or self adjusting characteristic of the sheet from which the back rest is made serves a dual function, it permits bending the back rest for combination with the bleacher seat, and because of this "memory," the releasable clamping or locking means are urged into back rest supporting and maintaining position on the bleacher seat, and this inherent "memory" also functions to automatically return the back rest to its flat transport and storage condition when the clamping or locking means is released from the bleacher seat.
