Title: A process for the solvent fractionation of animal or vegetable fats in general
IPC: A61Q19/00
Filed: 1979-01-12
Abstract: A process has been developed for the solvent fractionation of an animal or vegetable fat into distinctive fractions of well defined physical properties. The fat is partitioned into three fractions by only two crystallizations from acetone or other solvents. One is a semi-solid fat fraction resembling cocoa butter in melting properties which melts at about 36 DEG -38 DEG  C. Another is a high melting solid fat which melts above 45 DEG  C. The third fraction is an oil at room temperature. The invention also relates to the uses of these fractions either by themselves, by combination of the fractions themselves or in combination with other fatty materials such as cocoa butter or various animal or vegetable fatty materials to create fatty products for food or non-food use. The Examples relate to the fractionation of butter fat and palm oil, respectively.

Title: Releasable coupling
IPC: E02D5/24
Filed: 1980-04-09
Abstract: A high strength releasable coupling particularly adapted for quick and simple interconnection of piling sections has mating cylindrical male and female members (18, 20) releasably interlocked by multiple locking pins (22) passing tangentially through the members. The pins (22) are received within spaced sets (42a,42b,42c) of complemental bores (44) in the female member (20) and extend partially through a corresponding annular groove (26a,26b,26c) formed in the male member (18) whereby the members (18, 20) may be locked together in axial alignment without requiring rotation about their axes. The arrangement of the bores (44) in each set (42a,42b,42c) is such that the axes of the pins (22) circumscribe the male member (18) when the members (18, 20) are interlocked thereby evenly distributing axial loads on the coupling while also providing superior endurance to bending loads. In preferred forms each set (42a,42b,42c) of bores (44) is angularly offset about the axes of the members (18, 20) relative to the other bore sets for improved loading. <IMAGE>

Title: Colour television transmission
IPC: H04N11/24
Filed: 1980-05-06
Abstract: A colour television transmission system providing a colour television signal capable of being utilised in currently manufactured broadcast television receivers and in receivers adapted to produce a higher quality display. With the system the luminance information of a composite television signal is transmitted as an amplitude modulated carrier whilst the chrominance information is transmitted as a modulated subcarrier spaced from the carrier, the type of modulation depending on the type of transmission. The luminance modulated carrier has a lower sideband of greater bandwidth than the upper sideband and the chrominance modulated subcarrier is located above the carrier but outside the bandwidth of the upper sideband. The upper sideband contains sufficient luminance information for it to be utilised to produce a television picture of an acceptable quality on currently manufactured television receivers, whereas the adapted receivers use the lower sideband. <IMAGE>
