Filed: 1932-05-19
Abstract: 401,021. Enamels. EYER, P., 151, Quedlinburgerstrasse, Halberstadt, Germany. May 19, 1932, No. 14287. [Class 56.] A method of producing enamelled iron articles by a wet process consists in fusing directly on to the iron base a light-coloured glaze, using white opacifying agents which contain antimony oxide together with zinc oxide or zirconium oxide, or both. The zinc oxide or the zirconium oxide may be replaced partly or wholly by oxides of the alkaline earth metals or of the earth metals, particularly those which possess opacifying properties themselves. The mixture of antimony oxide with the other oxides is calcined, and compounds of aluminium or barium, or of both, together with oxidizing agents may be added to the mixture. The addition of barium components assists in the formation of the glaze and facilitates the adhesion of the cover glaze to the ground coat. About 1-10 parts of the opacifying agent are added to 100 parts of the ground glaze, either before fusion or during grinding in the mill. Compositions of suitable ground glazes are given in the Specification.

Title: Improvements in or relating to reel-adjustment devices for harvesting machines
IPC: A01D57/04
Filed: 1956-05-09
Abstract: 833,656. Mowing machines. CLAAS, A., and CLAAS, F., [trading as CLAAS GEB]. May 9, 1956 [May 9, 1955], No. 14418/56. Class 6(3). A harvesting machine comprises a reel 2 which is vertically adjustable on a tubular support 6 by means of a sprocket 17 engaging a roller chain 15 and mounted coaxially with the reel shaft 3, the latter being driven via bevel gears 22 and 23 from the shaft 21. The sprocket 17 is connected to a clutch plate 24 whereby the sprocket may be brought into driving engagement with the gear wheel 23 which is mounted on an extension of the reel shaft. Adjustment of the reel is effected by mean of a control lever 32 carrying a roller 31 which engages a cam surface on a lever 29 journalled in the gear housing 19. The lever 29 is provided with a rolling key 27 for engaging teeth on the periphery of the clutch plate. When the control lever is in the position I (see Fig. 8) the clutch plate is disconnected from the gear wheel and the clutch plate and sprocket are blocked since the rolling key engages one of the above teeth, and thus vertical movement of the reel is prevented. When the control lever is in the position II the clutch plate is still disconnected from the gear wheel 23, but the rolling key is disengaged from the teeth on the periphery of the clutch plate and the reel can move downwards under the action of gravity, rotating the sprocket against the roller chain 15. The abutting portions of the control lever 32 and counter lever 35 are so formed that when the former is moved to the position III the lining 25 on the clutch plate 24 is pressed into contact with the gear wheel 23, the sprocket 17 thereby being rotated so as to climb the roller chain 15, resulting in the upward displacement of the reel. A spring 37 urges the control lever into the position I. The implement is illustrated as comprising a crop divider which is of hollow, pyramidal form, but this is not specifically described in the Specification.

Patent GB-593008-A (GB)
Title: Improvements in applying vat dyestuffs to textile materials in package form
IPC: D06P1/22
Filed: 1945-06-08
Abstract: Textile materials are dyed in package form by circulating through the materials a suspension of an unreduced vat dyestuff containing a dispersing agent dissolved therein, gradually adding a water-soluble inorganic salt to cause substantially complete deposition of the dyestuff from the suspension on to the material, and thereafter reducing and subsequently oxidizing the vat dyestuff by any conventional method.  The materials may be of natural fibres or of viscose or cuprammonium rayon.  Common salt and Glauber's salt are mentioned as suitable salts for depositing the dyestuff from the suspension, and an excess is preferably added in order to ensure that no appreciable amount of leuco compound dissolves in the circulating liquor after reduction.  In an example, a suspension of "Caledon Blue RC paste fine" in water containing "Dispersol VL" (Registered Trade Mark) is circulated through cakes of viscose yarn, and common salt is gradually added to deposit the dye on the cake.  The dyestuff is then reduced by circulating a solution of caustic soda, sodium hydrosulphite and Formusol through the cake, followed by washing with cold water until the dye is oxidized.  Other examples include the dyeing of viscose spun yarn, loose viscose staple fibre, spun rayon piece goods, cuprammonium yarn, mercerized cotton yarn, viscose filament yarn and wool-viscose staple yarn, using various vat dyes.
