Title: Process and Apparatus of Drying Granular Materials.
Inventor: HUHN ANTON
IPC: F26B11/04
Filed: 1918-02-07
Abstract: 122,910. Huhn, A. Feb. 7, 1918. Continuous - discharge apparatus, rotary.-A process and rotary-drum apparatus for drying grain, flour, ores, &c., comprises the feeding of the material into, through, and out of the drum in such a manner that the entrance of air with the material is prevented and the production of a partial vacuum in the drum by the withdrawal therefrom of the released vapour and a regulated quantity of admitted air. A slightly inclined drum. 1@ turns on rollers 12, 13 mounted on end frames 10, 11 and is driven by gearing. The frame 10 carries a head 20 with an inwardly extending flange 21 through which projects the feed pipe 27. Flanges on the drum make a tight joint with the flange 21. The frame 11 carries the rear head 39 of the drum and a battery of steam pipes 36 extend from the head into the cylinder, some of them, such as 38, being secured to the head 20. The pipes communicate with a space 40, and supply pipes 42 enclosed by the pipes 36 communicate with a steam space 43 fed by a pipe 44. The pipes are held in position by plates 37 and are disposed mainly in the upper part of the drum. Material is supplied by a pipe 32 fitted with a gate 31, and this pipe is kept full to prevent air from entering the drum through the supply pipe, but a regulated quantity of air is admitted through a pivoted slide valve 34. The drum carries internal peripheral blades 35 which constantly lift the material and discharge it on to the steam pipes. The material is discharged through a hopper 59 and spout 60 into a box 61 having a hinged lid 62 actuated by the weight of the material, which thus prevents the entry of air. An opening 64 for examining the grain is provided in the spout. Air is drawn from the drum and pipe 60 through pipes 68, 67, 66, 65, and 69 by a blower 80, and passes through a cleaner 72 to remove dust &c. which collects in a chamber 74 and can be discharged through a slide 76 into a sock 77. The pipes 66 and 69 are fitted with slide valves 102, 83. In a slightly modified arrangement, a double cleaner is employed.

Title: Improvements in and relating to light reflectors
IPC: F21S13/00
Filed: 1938-07-18
Abstract: 513,149. Lamps. MORGAN, P. KING-. July 18 1938, No. 2255/39. Divided out of 499,643. [Class 75 (ii)] A truncated conical reflector 19 having a base angle of 40-45 degrees is adapted to be supported around a light source 6 with an interposed lens system 20 for concentrating light thereon. The reflecting surface may be constituted by mirrored glass or polished metal, preferably the metal obtained and treated as described in Specifications ' 433,484; 436,154, 436,481, [both in Group XXXVI], and 440,287, and may be coloured or associated with colour filters. A bowl or other shade may be associated with the reflector. The light source may be an electric incandescent-lamp, preferably having a filament in a single plane, an electric discharge lamp, or one or more incandescent gas mantles. The lens system is constituted by a single ring element or two or more segmental portions. As shown, the reflector 19 and lens 20 are mounted in a skeleton framework 21 connected by rods 22 to an a pertured disc 10, adapted to engage with the lamp cap 11 or be secured to the lampholder. Specification 150,737, [Class 75 (iv)], also is referred to.

Title: A flap device for skips and hoppers
IPC: B63B35/30
Filed: 1938-01-24
Abstract: 491,190. Guided skip hoists; ships; delivering material from hoppers. AUTOMATIC COAL CLEANING CO., Ltd. Jan. 24, 1938, Nos. 2275 and' 2276. Convention dates, Feb. 22, 1937 and Aug. 28; 1937. [Classes 78 (i), 78 (iii), and 78 (iv)] The hinged bottom door 3 of a skip, which is pivoted at 4, is normally held closed by pivoted links 5 carrying rollers 7 bearing against the outer ends of slots 9. As the raised skip approaches the dumping point, the rollers engage fixed guides 15 and are moved towards the left until the links pass the vertical position and allow the door to open. In the meantime the upper end of the door has passed the fixed stops 16, and the rollers 13 drop on to these stops and support the door so that it opens gradually as the lifting continues until finally it forms a delivery slot approximately in line with the surface 32. During the latter part of the opening movement the depending links 5 are dragged by the door until the rollers are again at the right-hand ends of the slots, in which position they support the open door just clear of the stops 16. On lowering the skip, the stops 16 initiate the closing movement of the door and the guides 15 complete it. Similar apparatus may be used to open and close the door of a fixed bunker for charging skips. In this case the link is hauled in both directions by a motor so that the roller is displaced from end to end of the slot. Fig. 5 shows the means adopted to prevent interference with the closing of the door by jamming at the hinge. The door plate 33 is bent right round the hinge 4 and terminates in a curved portion 38 that co-operates with the tapered end of the fixed wall 32 to remove collected material as the door closes. For narrow shafts the door is formed with a tailpiece extending below the hinge and the link and roller are fitted thereto. Fig. 7 shows a modified construction in which the door is supported by the spring 61 in the open position, and the slot 51 is made long enough to allow the door to compress the spring and move down to the position 63 if the roller 59 strikes the upper guide 57a in the event of an overwind. In the position 63 the door can slide over the inner surface of the guide without being fractured. In a modification of the construction shown in Fig. 7, the link and slot are below the door instead of above it. In a further modification, the door is moved to its lowest position on overwind, by a cam which normally supports it in the open position but is rotated by contact with a fixed stop in the shaft so that it allows the door to fall to the position in which it is free of obstructions.

Title: Improvements in or relating to adhesive dispersions of the oil-in-water type, and processes of preparing the same
IPC: C08J3/03
Filed: 1945-01-29
Abstract: An adhesive oil-in-water type dispersion comprises individual dispersed particles, each of which comprises an intimate blend of a polyvalent metal soap and rubber or rubber-like material such as polyisobutene.  Suitable soaps are zinc and calcium resinates such as are known as "Lisor" or under the Registered Trade Mark "Zitro," and magnesium, barium, lead or aluminium resinates. The rubber may be in the form of latex or reclaim.  The dispersion is prepared by mixing a restricted amount of water with the blend forming a water-in oil dispersion and inversion of phase is effected by addition of an aqueous alkaline solution of a hydrophilic organic colloid such as casein, methyl cellulose, sodium alginate or corn starch, followed by the remainder of the water.  Minor proportions of alkali metal soap dispersing agents are also generally used and may be formed in situ by the addition of rosin and caustic potash.  This soap may be sufficient to invert phase, but the colloid is still used to prevent re-inversion by the polyvalent metal soap.  The blending may be carried out in a heated mixer and the dispersion, with the addition of other optional ingredients, formed between room temperature and 210 DEG  F.  The polyvalent metal soap may be plasticized with mineral oil and thinners, e.g. isopropanol, n-butanol and ethyl acetate, may be added to the dispersion. Other additives include pigments, ester gum, oleic and acetic acids, polymerized trimethyl dihydro-quinoline, vulcanizing agents and anti-oxidants.ALSO:An adhesive oil-in-water type dispersion comprises individual dispersed particles, each of which comprises an intimate blend of a polyvalent metal soap and rubber-like material such as polyisobutene.
