Title: Feed mixing apparatus
IPC: A23N17/00
Filed: 1972-02-23
Abstract: 1369271 Mixing feeding stuffs DEERE & CO 23 Feb 1972 [23 Feb 1971] 8343/72 Heading B1C  In a feeding stuffs mixer of the kind in which the material is circulated in a container 58 by a vertical screw conveyer 78, the lower end of the conveyer housing 66 is at least as far from the container wall 68 as the upper end; as shown, they are parallel. The lower end of the conveyer carries an arm 88 which sweeps the bottom of the container; the arm is parallel to but set back from a radius (see Fig. 3, not shown) and its outer end is restrained by a guide flange 94. The arm has a non-symmetrical sharp leading edge, Fig. 5, and asists mixing by sweeping material towards the conveyer intake; the bottom of the cylindrical container may also have a slight inward slope. The upper end of the screw may have a material distributing paddle and plate 86, 87. As shown the mixer is mounted on a transport chassis together with a hammer mill 32, blower 48 and dust collector 56, the output of the mill and dust collector falling into a screw conveyer 46. Additives may be supplied from a hopper 96 and all the material is lifted up into the container by a paddle 102. The mixer is discharged by screw conveyers (110, 112, 114). All the apparatus is powered by a drive shaft 34 from the towing tractor.

Title: Metallised azo dyestuffs
Inventor: BLACKHALL ALEXANDER
IPC: C09B62/095
Filed: 1963-03-01
Abstract: The invention comprises chromium containing azo dyestuffs which, in the form of the free acids, are represented by the formula <FORM:1018996/C4-C5/1> where R represents a lower alkyl radical, one X represents -O- and the other -O- or -COO-, the benzene rings I and II are optionally substituted by one or more chlorine atoms, or nitro, lower alkyl, lower alkoxy, lower alkyl sulphonyl, sulphamyl or substituted sulphamyl, the benzene ring III is optionally substituted by one or more chlorine atoms or lower alkyl, lower alkoxy, sulphamyl or substituted sulphamyl groups; the benzene ring IV is optionally substituted by a lower alkyl group and one of the four benzene rings is substituted by a single sulphonic group.  The dyes are prepared by condensing an appropriate metal containing amino azo dye with a 2:4-dichloro-6-lower alkoxy-1:3:5-triazine or with a 2:4:6-trichloro-1:3:5-triazine and subsequently treating the product with an appropriate alcohol to convert one of the two chlorine atoms to a lower alkoxy group. "Lower alkyl" and "lower alkoxy" groups are defined as containing 1 to 4 carbon atoms. The dyes are suitable for colouring wool, silk, fibres of polyhexamethyleneadipamide, caprolactan polymer, polyurethane, polyacrylonitrile, leather and natural and regenerated cellulose fibres.  Examples are furnished.

Title: Improvements in or relating to a process of producing amines
IPC: C07D213/127
Filed: 1953-03-26
Abstract: 738,515. Electrolytic production of amines. ROHM & HAAS CO. March 26, 1953 [April 1, 1952], No. 8384/53. Drawings to Specification. Class 41. A process for converting a water-soluble salt of an amine into the free amine comprises passing a direct current through a cell having a cathode compartment which contains an aqueous solution of the amine salt, and an anode compartment which contains an aqueous electrolyte, the compartments being separated by an anionic permselective membrane containing at least 25 per cent by weight of an anionexchange resin. The amine may be methylamine, dimethylamine, trimethylamine, nbutylamine, sec.-butylamine, tert.-butylamine, methylethylamine, di-tert.-butylamine, aniline, methylaniline, di-ethylaniline, pyridine, cyclohexylamine, di-cyclohexylamine, alpha- and #- naphthylamine, ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, ethanolamine, or dimethylamino ethanol. The salt may be that of an amine with an acid such as sulphuric acid, hydrochloric acid, phosphoric acid, or acetic acid. The electrolyte may be a solution of sulphuric acid, hydrochloric acid, or sodium chloride. When the current is passed free amine accumulates in the cathode compartment, with liberation of hydrogen at the cathode, and, if the amine salt is a salt of sulphuric acid, sulphuric acid accumulates in the anode compartment with liberation of oxygen; if the salt is one of hydrochloric acid, chlorine is liberated at the anode. The permselective membrane may be such as described in Specification 721,161, [Group IV (a)]. Specifications 450,414, 489,173, 556,622, 557,414, [all in Group IV], 654,706, [Group IV (a)], 693,166 and 720,002 also are referred to.

Title: Improvements in the production of metallic screens by electrodeposition
IPC: C25D1/10
Filed: 1938-03-22
Abstract: 515,043. Production of perforated metallic sheets by electrodeposition. JACKSON, L. MELLERSH-. (Norris, Inc., E. O.). March 22, 1938, No. 8773. [Class 41] In preparing a matrix for the production of perforated metal sheets by electrodeposition, a metal, preferably copper, plate is provided with an etching resist of mesh form by the photographic half-tone process, it is then etched to form depressions and the resist is removed. The depressions 10, Fig. 4, are then partially filled with a plating resist 11 preferably in several layers each hardened by heat. A nickel coating 13 extending partially into the depressions at 14 is then plated on to the exposed metal. The filling of the depressions with a plating resist 11a is then completed, and the matrix after cleaning is ready for use. A thin film of wax is applied before electrodeposition to facilitate stripping. In a modification the filling 11a is depressed to a craterlike form. In another modification the top surface of the filling is rubbed down so as to expose part of the side coatings 14; in this case the screen formed by electrodeposition on the matrix is of the section shown in Fig. 9. The etching resist in mesh form is formed by photographing on the copper plate a cross-line half-tone screen, or by printing on to the sensitized plate through a screen having parallel lines, the screen being placed successively in two positions at right-angles to each other.

Title: A new or improved machine for producing screw threads by a grinding operation
IPC: B24B19/02
Filed: 1934-03-21
Abstract: 440,255. Grinding screw-threads. HARLEY, S. J., Long Bend, Old Leamington Road, Stivichall, and COVENTRY GAUGE & TOOL CO., Ltd., Earlsdon, both in Coventry. March 21, 1934, No. 8798. [Class 60] [See also Group XXXVII] In a machine for grinding screw-threads, the drive for the grinding-wheel and for the work-head is in each case of the Ward-Leonard type, and the machine, which comprises a bed 2 having thereon a reciprocable workslide 3, has mounted in a guard 14, a main driving motor 10, a generator 11 driving the grinding-wheel motor 8, a generator 12 driving the work motor 9, and an exciter 13 ; the grinding-wheel 7 and its motor 8 are carried by a head provided with a guard 14<a>. The slide 3 is traversed by a lead screw driven from a gear box 41, and the work is driven, through gearing in a work-head 4, from the gear box. When fluted work is to be treated, a cam associated with the work-head closes a switch whilst a flute is passing the grinding- wheel, thus increasing the speed of rotation of the work. Fig. 5 shows the electrical connections employed, the motors 8 and 9, and the generators 11, 12 respectively having shunt fields 8<a>, 9<a>, 11<a>, 12<a> separately excited from the exciter 13 and regulated by resistances 11<b>, 12<b>, 12<c>. Movement of the slide is controlled by limit switches 60, 61 controlling the coils 63, 62 of contactors 67, 68, the switches 60, 61 being operated by a lever 64 engaged by dogs 65, 66 on the slide, and switches 69 and 70 also are provided serving to give a quick-return movement to the slide ; a change-over switch 76 is employed for obtaining the movements required for lefthand threads, and by means of a switch 71 the speed of the slide is arranged to be the same in both directions of movement. The increase in speed of the rotation of the work during grinding of fluted work is brought about by means of the cam referred to above, which closes a switch 80 in circuit with a hand-operated switch 79 and the exciting coil 78 of a contactor 81 which, when closed, short circuits, as shown in dotted lines, the variable resistance 12<c> in the field of generator 12. The machine carries a switch panel on a door 90 with starting and stopping switches 91, 93, 94 thereon and also carrying control wheels 97, 98 for the resistances ; the stop switch for the grinding-wheel motor may be interlocked with that of the work head, so that if the wheel is stopped, so also is the work, and a safety switch may be provided rendering the machine inoperative when the door 90 is open.
