Title: Improvements in the preparation of mixtures, particularly of concrete
IPC: B28C5/08
Filed: 1962-07-02
Abstract: 993,803. Concrete mixers. P. AUGUST. July 2, 1962, No. 25203/62. Heading B1C. Dry mix materials are proportioned by weight and pre-mixed in batches in a loading skip which charges a continuous-discharge mixer. A concrete mixing plant has a drumshaped loading skip guided by wheels 10 and rollers 12 on rails 11 ; the wheels 10 operate a rotary stirring device (not depicted) in the drum. The drum is hoisted by a motor 13, winch 15 and cable 18; the motor may be a pole-changing reversible motor and automatically controlled at least in part in dependence on the motion of the drum. As the drum reaches its uppermost position the rollers 12 are guided along the path 19a, 19b, 19c and the wheels 10 along the path 11b, 11c whereby the drum is tilted and its contents are discharged from the outlet 9<SP>1</SP> across the full width of a shoot 3 feeding a continuous discharge mixer 1. The shoot 3 has a feeding screw 5 (which has an increasing conveying capacity towards its discharge end) feeding a mixing screw 4 ; water may be supplied by a transverse spray pipe 20 discharging upwards against a baffle 21. The mixer discharges into a storage container 24 suspended at one side on a spring 23 ; when the container is full its weight activates a switch 23 to stop the motor 8 driving the screws 4, 5, and also, if desired, to close a magnetically operated valve controlling the water supply.

Title: Method and apparatus for processing heat-softenable mineral materials and forming filaments therefrom
IPC: C03B37/09
Filed: 1965-06-15
Abstract: Heat-softenable materials such as glass are drawn into filaments through orifices in the bottom of a chamber to which is connected a horizontally-offset auxiliary chamber communicating by way of openings near its bottom with the main chamber a substantial distance below the top.  The material is melted in an electrically-heated tank 12 and is fed through apertures between guide wires 84 to an electrically-heated plate 86 terminating just below <PICT:1038815/C1/1> the level of liquid in the auxiliary chamber 68 whence it passes through holes in the dividing wall 561 into the main chamber 62.  The height of the liquid in the chambers is determined by a probe 94 which controls the supply of current to the tank 12. Disposed at a lower level in the main chamber is an electrically-heated perforated plate 110 to render the material more fluid and so assist in the release of gas bubbles.  The filaments issuing from the nozzles 18 are cooled by fins 115 extending between rows of nozzles from pipes 114 containing cooling water.  In order to provide a still greater volume of glass fed to the chamber 62, the auxiliary chamber and, if desired, the melting tank may be duplicated on the opposite side of the chamber 62.

Filed: 1928-09-06
Abstract: 326,216. Potts, H. E., (Plauson, H.). Sept. 6, 1928. Emulsions, making.-Paints or lacquers are produced by dissolving rubber, balata &c., in a saturated volatile organic solvent, vulcanizing under pressure at about 125‹ C, colloidalising the vulcanized product by heating it under pressure at a temperature up to 180‹ C, and suspending pigment in the dispersion of vulcanized rubber so formed. Resins such as hardened colophony or coumarone, or shellac substitutes may be added. As solvents saturated chlorinated hydrocarbons may be used, but dispersions in benzine or other saturated hydrocarbons are improved, as regards paintability, if organic acid anhydrides, such as acetic or -phthalic anhydrides or alkaline earth peroxides are added. The use of chlorinated hydrocarbons is stated to produce a. proportion of chlorinated rubber resin in the product. In examples, rubber or balata is dissolved in benzine (saturated) or acetylene or carbon tetrachlorides, and sulphur is added. Vulcanization is effected at 125‹ C. for 3-4 hours under 5-10 atmospheres pressure. The product is then heated for a short time at 100-180‹ C. under about 40 atmospheres pressure. After cooling, free sulphur is removed as by centrifuging, settling &c., and colloidalised Scheele's green or emerald green or a mercury colour with or without ochre, iron oxide, &c., is added. Non-poisonous colours such as dyes and lakes may also be employed.
