IPC: A21D2/02
Filed: 1939-05-20
Abstract: 529,110. Cereal preparations. JONES, C. R., and GREER, E. N. May 20, 1939, No. 15109. [Class 49] In the treatment of flour with activated carbon by admixture therewith to remove objectionable smells and flavours, the carbon is primarily mixed with a relatively small quantity of flour and after removal of 95 to 98 per cent of the flour the carbon-flour residue is mixed with the flour to be treated and after standing for a period, 95 to 98 per cent of the flour is finally separated therefrom. The granular carbon is thereby freed of black dust before using. The carbon-flour residue from each treatment can be used for a fresh batch of flour. A proportion of 0.1 per cent of active carbon to the flour to be treated is specified and the mixture stood for 24 hours.

Title: Improvements relating to heads of wax or other substances used for advertisements, shows, or exhibitions
IPC: A63H3/40
Filed: 1925-06-12
Abstract: 249,373. Berlize, T. C. A., and Berlize, T. P. F. June 12, 1925. Forms and models with characteristic movements.-An advertising head of wax &c. of the type provided with eyes adapted to move in all directions, and with moving eyelids is operated by power-driven mechanism. The eyes D are mounted on gimbals, the inner member of each of which, controlling the horizontal movement of the eye, has fixed to it an arm F pivoted to a floating link H. A projection I on this link is embraced by a fork at the free end of a lever 0 pivoted at O<1>. The lever O is oscillated by a cam N on a continuously rotating shaft J. Geared to the shaft J by wheels L, M, differing slightly in size to ensure a long period before the same combination of movements is repeated, is a shaft K carrying a cam P whereby vertical movement of the eye is effected. The cam P oscillates a bell-crank Q which through a rod R swings the outer members of the gimbals, ball joints being provided in the connecting links. To reduce the extent of vertical movement of the eyes when near their extreme horizontal positions, the longitudinal motion of the rod R for a given angular swing of the crank Q is varied by mounting its pivot e slidably in a slot in the crank Q. The position of the pivot e in the slot is controlled by a cam a on the shaft J. The sliding pivot may be otherwise located. The eyelids f are pivoted to a bracket h, Fig. 4, and connected by a link l to a bell-crank k pivoted at k<1> and carrying two rollers y which bear respectively on cams or cam flanges j mounted one on the top of each shaft J, K. As the shafts J, K rotate at different speeds, the depressions in the cams j will coincide only at intervals, the occasions of full coincidence giving maximum motion to the eyelids, and partial coincidence a lesser motion. The cams j, P are arranged so that the eyelids will not be lowered when the eyeball is raised. A supplementary device for regulating the amplitude of the eyelid motion consists of a, cam o, Fig. 8, rotating at a speed preferably differing from that of shaft J or K, and controlling a crank n which by a link m adjusts the position of the link l in a slot in the crank k. Alternatively the slot may be located in the eyelid support g, Fig. 4. One cam j only may be employed with the supplementary device. The eyes may be lit up by lamps located behind, and illuminated either continuously or intermittently under control of a commutator mounted on one of the shafts J, K, or on a special shaft. Instead of lamps, light may be conveyed to the eyes by mirrors or prisms. The different shafts may be driven by independent motors.
