Abstract: 1,202,098. Storing silage, grain &c. TEXAS INDUSTRIES Inc. 21 March, 1968 [28 March, 1967], No. 13828/68. Heading A1F. A crop store or silo has a rigid body portion 2 and a flexible upper portion 6 with means being provided for air to be withdrawn from a lower region of the silo. The flexible portion 6 is bag shaped and is attached at its open end to a vertical wall of the lower rigid body portion. The lower portion of the body has a feeding channel 9 through which crop is fed by means of the tines 18, the curved reciprocating member 14 and the reciprocating piston 10. The crop is held inside the silo by means of the spring biased flaps 27. The conveyer 24 and the screw auger (22), Fig. 2 (not shown), are arranged to feed crop into an opening (16) from where it is acted upon by the tines 18. The silo has an outlet opening 41 whose lowermost end communicates with a laterally directed portion 43. This portion 43 and the feeding channel 9 being closable by hydraulically operable flaps 65 and 66 respectively. A vertical shaft 44 transmits the power of an electric motor 45 to a screw auger 49. The screw auger 49 rotates about the shaft 48 and also about the shaft 44. Ejected material is carried away by a conveyer 64 and the flap 65 is retained in a closed position by the catch 71. An inward facing channel sectioned ring 52 surrounds the silo and communicates with it by means of a grating 53 of wire mesh or the like. The ring can be selectively connected to either the pressure or suction sides of a double acting pump 58. A duct 59 selectively connects the upper part of the silo on the side of the flexible bag remote from that where the crop is disposed to either side of the pump 58. In an embodiment, Fig. 5 (not shown), the gauze mesh 53 is replaced by a plurality of holes in the body of the silo, the flexible bag (77) is not surrounded by the rigid body portion and the screw auger 49 is replaced by a series of blades 85. In a further embodiment, Figs. 6, 7, 9 and 10 (not shown) the flexible bag (94) is removably attached to the rigid body portion which is partially buried so that on removal of the flexible portion crop may be dropped into the silo. Air is removed from the lower portion by means of a plurality of rings (89-91) each formed with a plurality of apertures and connected to a suction pump (93). In a further embodiment, Fig. 11, a flexible hose 118 selectively connects the inside of the body 2 on the side of the flexible portion 6 remote from that on which crop is disposed to a suction pump 121 or a source of water under pressure. The water is removed from the silo by the pump or by siphoning. The body of the silo may be constructed from a plurality of elements formed from a synthetic resin or plastics material, each element having bent-over rims for attachment to other elements with the aid of a sealing adhesive.

Patent GB-848054-A (GB)
Title: Improvements in or relating to the manufacture of lubricating grease compositions
Filed: 1959-04-27
Abstract: A lubricating grease composition is manufactured by preparing an aqueous suspension containing a clay and a water-insoluble dye in a weight ratio between 1:10 and 10:1, adding a lubricating oil to the suspension, substantially dehydrating the mixture and shearing the dehydrated product.  The waterinsoluble dye employed is an indanthrene compound, an indogen compound, a phthalocyanine, an N - acyl derivative of 9,10-dihydroxyl-1,4-diamino-anthracene, an N-acyl derivative of 9,10-dihydroxy - 1,2 - diamino-anthracene or an N-acyl derivative of diamino-anthraquinone.  The lubricating oil may be mineral or synthetic, examples of synthetic oils being alkyl esters of mono- or dicarboxylic esters, polyglycols or their esters or ethers, complex esters, phosphate or sulphite esters (including those derived from the monomethyl ether of ethylene glycol), carbonate esters, halocarbon oils, silicones (including chlorophenyl silicones), mercaptals and formals.  Indanthrene compounds mentioned are flavanthrone, indanthrone, pyranthrone, violanthrone, and di- or tri-chloroindanthrone.  The indogen compounds may carry substituents such as hydroxy, carboxy or nitro groups or halogen atoms, specific compounds being indigo, iso-indigo, 3 - keto - indoline, isatide and isatin.  The phthalocyanines include not only metal-free phthalocyanine but also metal phthalocyanines, chlorinated phthalocyanine and chlorinated metal phthalocyanines.  The clay employed, e.g. bentonite or bectorite, may be modified by treating the aqueous clay slurry with a phosphorus acid (especially phosphoric acid) to increase the waterresistant properties of the grease.  The mixture of grease ingredients may be dehydrated by distillation (especially in the presence of an azeotroping agent, e.g. an alcohol, ketone or ester) or by solvent replacement with a watermiscible liquid (e.g. acetone or isopropyl alcohol).  In the examples, grease compositions are prepared from (1) hectorite, phosphoric acid, indanthrone and methyl phenyl silicone oil, (2) hectorite, phosphoric acid, indigo and bright stock or (3) bentonite, phosphoric acid, copper phthalocyanine and methyl phenyl silicone oil.  Specification 846,223 is referred to.
