Abstract: 1,232,790. Spreading butter and like spreadable substances. SPIRO ENG. Ltd. 20 Dec., 1968 [22 Dec., 1967], No. 58404/67. Heading A2A. Apparatus for spreading butter (or like spreadable substances) on bread, rolls, cake, or other baked articles having a flat surface to receive the butter comprises a container 10 for the butter, a rotatable butter-applying roller 15, a rotatable kneading member 18 having axially spaced pairs of opposed teeth 19 on it which pass between correspondingly axially spaced projections 20 fixed to the container, and means (e.g. an inclined conveyer belt 11, Fig. 1, not shown) for feeding slices of bread or similar baked articles tangentially against the periphery of the butter-applying roller. The teeth 19 are preferably triangular in form (as seen in a direction perpendicular to the axis of the member 18, Fig. 3, not shown). A roller 17 is preferably included to feed the butter towards the kneading member. The rollers 15 and 17, the member 18, and the belt 11 are driven through a belt and gearing 30-32. A plate 22 which is carried by arms 23 pivoted about the axis of roller 17 prevents butter passing between the rollers 15 and 17. The butter thickness is regulated by an adjustable plate 21.

Abstract: 1,233,694. 694. Jet propulsion nozzles. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Jan. 15, 1969 [Jan. 19, 1968], No.2298/69. Heading F1J. . A variable area jet propulsion nozzle having a series of inner flaps 4 pivoted on tangential spindles 17 adjacent the downstream end of a fixed duct 3 and controlled by jacks 6 has a synchronizing device to ensure that all the flaps move in unison. The flap spindles 17 are supported by longitudinal side plates 10a, 10b which are each secured to the duct 3 by a spindle 11a passing through a yoke 11 bolted at 11b to the duct and by a boss 10c on the side plate engaging an aperture 3c in a circular flange 3b on the duct. This mounting permits relative thermal expansion between the duct 3 and side plates 10a, 10b. The latter also support the jacks 6 by way of pivots 9. Each jack 6 is aligned with its respective flap 4 and connected thereto by its piston rod 6a and a spindle 16 passing through ribs 4a, 4b on the flap. Each end of the spindle 16 carries a link 15, each of which is pivoted to a lever 12 pivoted to adjacent side plates 10a, 10b at 13. Thus all the flaps 4 are interconnected by way of the links 15 and levers 12 so as to move in unison even in the event of failure of a jack 6. As seen in Fig. 1, the geometric figure formed by the pivots 13, 14, 16, 17 is a parallelogram, the side 17-13 being fixed and parallel to the nozzle axis and the side 14-16 formed by link 15, also remaining parallel to the nozzle axis. Follower flaps 24 are disposed between the jack controlled flaps 4. Outer fairing flaps 5 are pivoted to the side plates 10a, 10b by spindles 19 and members 18, the flaps 5, being connected to move with flaps 4 by links 22. The flaps 5 may have their own synchronizing device. Cooling air may pass through the annular spaces between the nacelle 1 and duct 3 and between the latter and an inner liner 8.
