Title: Printing inks
IPC: C08G63/695
Filed: 1980-04-23
Abstract: A modified drying or semi-drying oil equivalent for use in the formulation of an alkyd resin system for the ink vehicle of a lithographic printing ink contains within its chemical structure linkages which are readily cleavable under mildly alkaline conditions. In particular the invention includes oil equivalents of formula I R<s1>s-X-(R<s3>sR<s4>s)Y-X-R<u2>u, wherein R<s1>s and R<s2>s comprise unsaturated aliphatic groups, especially ethylenically unsaturated C<u10-24>u aliphatic groups e.g. linoleic residues; X comprises an alkali labile bridging group, preferably a sulphur, an acyloxy, a nitrogen or especially an oxygen bridging group; Y comprises silicon (Si) or titatium (Ti), and R3 and R4 comprise aliphatic, aromatic or araliphatic groups or groups of formula R<s1>s-X- or R<s2>s-X-, wherein R<S1>s, R<s2>s and X are as previously defined. Preferred oil equivalents in which the R-X-substituents are amine or alcohol residues are prepared by ammonolysis or alcoholysis of the corresponding amine or alcohol with a suitable substituted silane or titanate precursor. The oil equivalent is incorporated e.g. from about 5 to about 50% by weight, in alkyd resin systems with typical alkyd polymer chain material, and the alkyd resin systems are blended e.g. up to about 10% by weight, in lithographic printing ink compositions with pigment and diluent. These ink composites advantageously exhibit improved de-inking properties as compared with prior art lithographic inks.

Patent GB-808447-A (GB)
Abstract: 808,447. Automatic control systems for gyroscopes. SOC. D'APPLICATIONS GENERALE D'ELECTRICITE ET DE MECANIQUE S.A.G.E.M. July 23, 1956 [July 29, 1955], No. 22722/56. Class 38 (4). [Also in Group XX] A gyroscope suspended about its centre of gravity is automatically corrected for tilt by a processing torque motor controlled by a vertical detector having a time constant adjustable to greater than one fourth that of the gyro and the torque motor. Tilt of a ship-borne gyroscope about a horizontal axis is detected, as shown in Fig. 3, by inequality in the heights of gravityresponsive conducting liquid 8 in the limbs of a U-tube formed in a metal body 5 carried by the gyroscope. This upsets the balance of conductivity between metal body 5 and separate, otherwise insulated, electrodes b so that, as shown in Fig. 4, an A.C. output is produced from a transformer 11 in such a phase-sense that the tilt is corrected by energizing, through an amplifier 12, an induction torque motor 6 to process the gyro in the appropriate sense. The time constant of response of the tilt detector, determined by the setting of a needle valve 10 restricting liquid flow in the U-tube, is adjusted to be greater than one fourth of the torque motor-gyroscope combination. In the case of a gyro vertical, two gravity-responsive U-tubes mounted at right angles on the gyroscope casing control separate motors processing the gyroscope about perpendicular axes. Compensation for the earth's rotation may be provided by a signal, dependent on latitude, which is applied to a sine-cosine resolver deriving two outputs which are respectively injected into the control amplifiers associated with the two torque motors. Compensation for gyratory acceleration may be provided by a signal, dependent on the ship's speed and rate of change of heading, which is injected into the amplifier associated with the appropriate torque motor. Compensation for longitudinal acceleration may also be provided by a signal, dependent on such acceleration, which is injected into the amplifier associated with the appropriate torque motor. Pick-offs associated with the two horizontal axes of the gyroscope may also control, through a correspondence control system, remote indicators or a platform which may support the gyroscope itself so that the gravity-responsive U-tubes may be mounted on the platform instead of on the gyroscope casing. In the case of a gyroscope having a horizontal spin axis the gravity-responsive U-tube is mounted either on the gyroscope casing or a vertical gimbal ring. The torque motors may be arranged to be de-energized if horizontal acceleration exceeds a predetermined value.
