Abstract: A mixture comprising a natural tannin material and formaldehyde or its equivalent, with or without fillers, plasticizers, colouring matter and lubricants, is moulded by heat and pressure. The formaldehyde equivalent may be solid, e.g. hexamethylenetetramine or paraformaldehyde; or the formaldehyde or its equivalent, or the tannin material, or both, may be added to the filler as solutions or dispersions and the water or other solvent or dispersion medium evaporated.  Acidic or basic catalysts, e.g. phthalic anhydride or sodium formate, may be employed.  Suitable tannin materials are catechin, quebracho tannin, mangrove cutch, wattle bark extract, hemlock tannin, kino-tannin, and pistacia tannin.  In examples: (1)-(3) mixtures of catechin, hexamethylenetetramine, and woodmeal alone or with (2) stearic acid or (3) stearic acid, phthalic anhydride, and paraformaldehyde, are hot-pressed; (4) a mixture of catechin, woodmeal, paraformaldehyde, sodium formate, and stearic acid is hot-pressed; (5) woodmeal is mixed with alcoholic solutions of catechin and phthalic anhydride, the alcohol evaporated, and the mixture ground with paraformaldehyde and stearic acid and hot-pressed; (6), (7) woodmeal is mixed with an aqueous solution of "Star & Crescent" Gambier, the water evaporated, an alcoholic solution of (6) phthalic anhydride, (7) a heathardening phenolic resin prepared from cresol and formaldehyde, added and the composition mixed with paraformaldehyde and stearic acid and hot-pressed; (8) woodmeal is mixed with an aqueous solution of "Star & Crescent" Gambier, the water evaporated, the product mixed with paraformaldehyde, and hot-pressed; (9) woodmeal is mixed with liquid Gambier, dried, and ground, then mixed with paraformaldehyde with or without plasticizers such as tricresyl phosphate, butyl stearate, and benzyl-cresol, and hot-pressed; (10) woodmeal is mixed with aqueous mimosa extract, dried, mixed with an alcoholic solution of phthalic anhydride, and the alcohol evaporated, then the composition mixed with paraformaldehyde and stearic acid and hot-pressed.

Title: Improvements in feeding hopper for use in pneumatic conveying systems
IPC: A21C1/14
Filed: 1954-02-22
Abstract: 774,982. Pneumatic conveyers. FULLER CO. Feb. 22, 1954 [March 11, 1953], No. 30154/55. Divided out of 774,980. Class 78 (1). Pulverulent material, e.g. flour, to be conveyed pneumatically through a pipe 43, Fig. 1, is contained in a hopper 1 which has means for dividing its interior into compartments and regulating the flow from the respective compartments through the outlet 16 into a rotary discharger 31. The bottom of the hopper comprises inclined gas permeable members 8, 9 through which gas passes into the flour from plenum chambers 10, 11. The permeable members slope towards the outlet 16. The flow of material is regulated by a pivoted plate 19 which is shown in Fig. 1 in its extreme positions 19, 19<SP>1</SP> and in an intermediate position 19<SP>11</SP>. In its extreme positions 19, 19<SP>1</SP> the flow of material from the members 8, 9 respectively, is stopped. The plate 19 is fast on a shaft 20, which is connected by worm gearing 21, 23, Fig. 3, to a shaft 24. This shaft is rotated by a hand-wheel 27 and is locked in any position by screwing-up a threaded member 28. An indicator 29 fast on the shaft 20 in conjunction with a scale 30 shows the position of the plate 19. If two materials having different conveying characteristics are dumped into opposite sides of the hopper, they can be blended in any proportion by adjusting the position of the plate 19. Inclined plates 48, 49 are disposed in the hopper above the plate 19 to disperse the material blown upwards by the release of compressed air from the pockets of the discharger as they enter the opening 16. A guard grid 55 in the hopper prevents a flour bag from falling into the discharger if dropped accidentally.

A filter may be located and connected to the inlet side of the water supply to the aerating/mixing device or the outlet side of the mineral dissolving means or both, for the removal of objectionable solid particles and sterilizing agents contained in the water. The aerating!mixing device is in the form of a body unit 11 to which a CO 2  bottle 19 is connectable and which supplies CO 2  via a spring biassed valve 27, 24 which is engageable with a spring biassed diaphragm 30, 34 which together controls the pressure of CO 2  in a cavity 23 in the body 11. A passage 47 connects the cavity 23 with a needle valve 48 and chamber 43 which controls the passage of the CO 2  to a base chamber 45, 46 by way of an automatic valve 50 and throttle valve 52. The water supply is connected to the body 11 at 15 and enters through a ball check valve 61, 62 and is connected to the chamber 45 by a duct 60. The throttle valve 52 and automatic valve 50 operate in conjunction with a further spring biassed diaphragm to control the pressure of CO 2  entering the water in the chamber 45 and which when combined passes through bore 63 to the mineral dissolver where-by controlling the flow of carbonated water there-through 'minerals preferably calcium carbonate are absorbed into the water. The mineral dissolver is in the form of a container 501 with a porous filter 504 downstream of the inlet 502 and a further filter 506 at the upper end of the container next to the outlet 503 and the mineral CaCO 3  is packed between the filters at a predetermined density. The upper filter is in the form of a plurality of filter cloth layers and various construction are indicated in Fig. 6a, 6b and 6c (not shown). The physical size of the dissolver, the density of active materials and the rate of flow therethrough are controllable factors in the optium operation of the apparatus.
