Title: Coating PVC film etc. with PVA - by plasma treatment and application of aq. PVA soln., gives reduced gas permeability and improved antistatic properties
IPC: C08J7/048
Filed: 1980-07-08
Abstract: PVC articles are provided with a coating layer of polyvinyl alcohol (PVA) applied directly without an intermediate adhesive layer. Pref. the surface of the PVC is subjected to an atmos. of low temp. plasma of a gas which does not polymerise in the plasma state, and the treated article is coated with aq. PVA soln. and allowed to dry. coating is carried out e.g. within 24 hours of the plasma exposure and the PVA coating is dried e.g. at 50-70 deg.C. The process is esp. useful for treating vinyl chloride (co)polymer films to give reduced gas permeability, improved antistatic properties, improved mechanical strength, improved chemical resistance and improved scratch resistance.

Title: Electronically controlled record-player - has automatic speed adjustment to account for any eccentricity in record being played
IPC: G11B19/28
Filed: 1982-02-05
Abstract: Radial eccentricity in an L.P. record of only 0.1 mm can cause a variation in tone of 0.4%. Motor speed is therefore continuously controlled to take account of eccentricity. The eccentricity is monitored by means of transducers mounted on an arm under the turntable which is mounted on the same axis as the pick-up arm on the record. The signal from the transducer controls a voltage-controlled oscillator which is part of a phase-locked loop motor drive circuit. The transducer can be a lightweight potentiometer, an air-dielectric capacitor or, at greater cost, a Doppler shift laser transducer.

Patent PT-70004-A (PT)
IPC: C08G/
Filed: 1979-07-31
Abstract: Through condensation ortho- and para-isomers of methylene dianiline (MDA) as well as PMPPA are produced as condensation products from arylamines, especially from aniline, and formaldehyde in the presence of acid catalysts, in which at least one component is a perfluoro-carbonic acid. From this mixture of the condensation products, 4,4'-MDA (p-isomer) of high purity is obtained by crystallization while the homogeneous aqueous solution obtained is being cooled down. It has been discovered that the 4,4'-MDA salts of the perfluoro-carbonic acids are less soluble in water than the corresponding salts of the o-isomers and the PMPPA.
