Title: Cold pilger rolling of tubes, esp. steel tubes - to achieve max. output of tube with accurate dimensions for mfg. ball bearing races
Inventor: HAGEDORN WILLI
IPC: B21B21/04
Filed: 1980-08-25
Abstract: Cold pilger rolling of tubes, esp. to mfr. races for ball bearings. The tube is rolled onto a stationary mandrel via a pair of grooved rolls rotating in a reciprocating roll stand.

Title: Tyre tread pattern for touring cars - with channel profiles which give low road noise
Inventor: MOUTIER ROBERT
IPC: B60C11/04
Filed: 1981-05-06
Abstract: A tyre tread pattern for touring vehicles features a combination of twin circumferential channels and undulating lateral channels such that the distance between the channels is approx. 1/5th of the tread contact width and the lateral channels extend over the tread shoulders and at least halfway across the tread face to the adjacent circumferential channel. The lateral channels are linked to each other and to the circumferential channels by narrow slits so that the tread is subdivided into partially overlapping transverse rows of blocks. Compared with a combination of sinusoidal and oblique channels, reduces road noise at higher speeds without undue loss of directional stability, braking grip or drainage.

Title: Passive fibre=optic hydrophone utilising interferometer - comprises two paths in transparent plate of refractive index varied by electric field
Inventor: DUCHET CHRISTIAN
IPC: G01H9/00
Filed: 1981-06-25
Abstract: A beam splitter divides the beam from a laser for detection by a reference photodetector and for an injection system. The injection system transmits the light along an optical fibre to an acoustic sensor. This contains a piezo electric transducer whose outputs are applied to an electro optic transducer to modulate the light through two electrodes which vary the refractive index in two arms of the optical transducer. The arms recombine in an output guide to transmit the modulated light along a return optical fibre. A photodetector receives this light for application to an electronic unit. This eliminates intensity fluctuations from the laser as received by the reference photodiode to produce a signal representing the received acoustic signal. The transducer has an interferometer of the integrated Mach-Zehnder type.
