Title: Optical measuring instrument using flat light beam - has camera to record dimensions of formed section
Inventor: PETIT PIERRE
IPC: B21B38/04
Filed: 1975-03-28
Abstract: The optical device is for measuring the dimension of a formed-section structural member such as an 'H' girder and may be used during fabrication rolling of the member. The device has a light source and a slotted panel. A light beam is projected through a lens onto a formed-section. A camera (5) is used to measure the thickness of a webb of the formed-section. The camera is set at an angle to the light beam to avoid optical interference. The picture detected by the camera (5) consists of a broken light beam. The segments of this light beam are counted to determine the position of the outlines of the formed-section.

Title: Large dia pipe bending machine - has eccentric clamping jaws and discs connected to traction mechanism
Inventor: NISTRATOV A F
IPC: B21D7/025
Filed: 1975-06-06
Abstract: The pipe bending machine for large diamter pipes produces pipe bends without thinned-out walls. The bending mechanism is mounted on a shaft and works in conjunction with an eccentric jaw clamp and a set of discs and traction elements, which cannect the bending mechanism with a feed mechanis. The discs are arranged on either side of the clamping device. The distance between the centreline of the shaft and the area of contact of the traction element with the disc exceeds the distance between the shaft centre- line and the centre of the clear width between the effective surfaces of the jaws, when the latter are closed.

Title: Automatic opening of parachutes for paratroops - involves successive bag releases and strap extension to prevent parachute striking aircraft
Inventor: ROUSSEAU JACQUES
IPC: B64D17/60
Filed: 1975-06-23
Abstract: The parachute is contained in a bag fixed to the paratrooper's back. The main bag contains a smaller bag (4) which is attached to the release strap (1) and to the stabilising strap (9). The stabilising strap (9) ensures that the paratrooper swings into an upright position (A). The bag (4) is then pulled out of the main bag and the parachute is pulled out (B). As the force on the release strap (1) is increased, the strap (14) is stretched before the load is sufficient to break the connecting cord (18). The time delay in stretching the strap (14) allows the parachute to swing to a lower position (C). When the cord (18) breaks and releases (D) the parachute, it is clear of the aircraft.

Title: Aromatic amines prodn. by catalytic hydrogenation of mono-nitro cpds. - using amine as solvent and avoiding formation of aq. phase
Inventor: DOUBOVETZKY SERGE
IPC: C07C209/36
Filed: 1975-09-17
Abstract: A continuous process for the prepn. of aromatic amines comprises catalystic hydrogenation of mononitro cpds. with the catalyst suspended in the liq. phase which comprises the amine to be produced as a solvent. The amine is recycled to the reactor having a water content below saturation and the amt. recycled is such that the formation of an aq. phase in the reactor is avoided. The process is used esp. for aniline and also for chloroanilines, toluidines, hydrocyanilines and diamines. Previous processes using the amine as solvent have avoided the formation of an aq. phase either by using excess gas, which is costly, or by a higher reaction temp. which leads to more by-prods. and lower productivity. The above provides a simple means of overcoming this problem. Pref. the amt. of amine recycled in ratio to the amine produced is not >10. The recycled amine contains is not >10% water and/or the above ratio is 0.1-10. A pref. process for aniline employs a recycling ratio as above of 0.5-5, esp. 1-1.5, a temp. of 120-150 degrees C and a hydrogen pressure of 10-20 atmos.

Title: Generation of energy utilising rotation of earth - motion of gyroscope mounting drives electric generator
IPC: F03G3/08
Filed: 1975-11-04
Abstract: The rotor (S) of the gyroscope (G) is mounted on a spindle with axis (XX) which is aligned on a circumpolar star (C).

Title: Purificn. of waste water and sewage - by air diffusion in presence of activated sludge (BR 28.6.77)
IPC: C02F3/12
Filed: 1976-06-02
Abstract: Domestic or industrial waste, previously settled in a sludge tank, is introduced through the inlet into the aeration chamber. The liq. mass is transported by a pump and a diffuser which is fitted inside with a number of constrictions and central zones. These force the liq. passing through to contract and expand alternately along the length of the diffuser. The mixt. thus obtd. with dispersed air bubbles, passes into an extension; at the lower end the air rises to the surface through the in-coming liq. and supplies oxygen for its purifcn. After a pre-determined time the liq. passes to the decantation chamber where the flocules of activated sludge separate out and are re-cycled; the purified liq. is evacuated through an outlet. Efficient purificn. is effected in a low cost single unit.

Title: Submarine cable having small bending radius - has corrugated or stamped screen conductor surrounded by insulating liq. in outer cylindrical casing
Inventor: DAVAY LOUIS LE
IPC: H01B7/14
Filed: 1976-06-04
Abstract: Submarine cable having a small bending radius allowing it to be easily handled through rollers etc. Maximum flexibility is based on the use of a corrugated screen conductor (5) rather than the plain conductor often employed. The space between the screen and the insulation (2) surrounding the cable center conductor (3) caused by having a corrugated screen is filled with a low loss material (7) such as polyethylene grease. This also serves to prevent hydraulic pressure compressing the screen. An alternative form of screen consists of an overlapped plain screen which has triangular sections pressed out forming a toothed surface. Neither form of screen is complete in cross-section, ie. screening is achieved by overlap.

Patent FR-2323029-A1 (FR)
Inventor: BRCAR ANTON
IPC: F03B3/10
Filed: 1976-08-05
Abstract: The pump turbine has three rotor wheels (2, 3; 4), two (2, 3) of which are accommodated in chambers separated from one another, aligned in opposite directions in a common housing (5), whilst the third rotor wheel (4) is seated at an interval above the adjacent wheel (3) on the common shaft (1). In pump operation the water flows out of a pipeline (24) through the first rotor wheel (2), through a second pipeline (26), through the third rotor wheel (4) and the second rotor wheel (3) to the high pressure pipeline (23). In turbine operation, the pipelines (24, 26) and hence also the first rotor wheel (2) are shut off from the water. The water now flows from the high pressure pipeline (23) by way of the second rotor wheel (3) and the third rotor wheel (4) to the low pressure pipeline (22). The first rotor wheel (2) can be seated with a sprag clutch on the shaft (1) so that in turbine operation it can be at rest. Fixed guide vanes, adjustable to the other rotor wheels (16, 20) are assigned to the first rotor wheel (2). Improved control can thereby be achieved both in pump operation and in turbine operation.

Title: Abnormal movement detection during transportation - is indicated by movement of supported spherical mass in rigid enclosure
IPC: G01P13/00
Filed: 1977-06-08
Abstract: Fragile goods are packaged for protection during transportation and litigation may ensue from any damage received. Detection of shocks likely to cause damage is indicated by movement of the support for a mass. A spherical mass (1) is maintained in a stable position between a transport plate (2) and a crater support (3) which is firmly mounted in the base of a rigid cylindrical enclosure (4). Shock or deformation applied (5) to the enclosure which exceeds a predetermined threshold will cause the mass to change position. Movement can be indicated by reference to markings on the transparent cover plate.
