Patent GB-674479-A (GB)
Title: Felting machine
IPC: D04H17/12
Filed: 1950-06-13
Abstract: 674,479. Conveyers. CASSE, M. June 13,1950. [July 5, 1949] No. 14701/50. Class 78 (i). [Also in Groups VII and VIII] A machine for felting hat bodies has at least two felting mills or felting layers to operate successively on the hat bodies and conveyer means to allow any number of successive passes to be made, the position of the bodies relative to the mill rollers being altered by the conveyer between each mill or layer. Means for automatic cozing are also provided. In the first embodiment, Fig. 1, two mills, F<SP>1</SP>, F<SP>2</SP>, have a conveyer M between them comprising spaced discs keyed on shafts driven from the spindle of a roller 7c of the mill F2 the discs of the middle three shafts being longer at the ends of the shafts than at the centre or viceversa so that the hat bodies are displaced transversely relative to the rollers of the mills while on the conveyer. In operation, hat bodies B1 are placed on a conveyer 16 which comprises a number of parallel belts driven by gearing 19a, 19b, 19c, from a roller 7a of the mill F<SP>1</SP> and are then fed to the first mill F<SP>1</SP> and finally deposited by it on the conveyer M which alters their position relative to the mill rollers before they enter the second mill F<SP>2</SP> from which a shoot 33 deposits them on a conveyer 34. The conveyer 34, comprising a number of parallel belts, is driven by a pulley 39 preferably at a different speed from-the belts 16 so that where the two conveyers are in contact as between the rollers 17, 18 automatic cozing takes place. A device 46 causes the bodies to fall back on to the conveyer 16 to repeat passes through the mills until felting is completed. In the modified embodiment, Fig. 7, a single felting mill, having two felting layers is provided, the conveyer M<SP>1</SP> between the two layers comprising an upper part ml and a lower part m2 driven at different speeds from the rollers of the mill. The upper part m<SP>1</SP> comprises parallel belts 50 passing over equal sized pulleys 51 and over pulleys 56 keyed to a shaft 57, which are of different size at the ends of the shafts as in the case of the discs in the first embodiment so as to displace the bodies transversely while on the conveyer. The lower part m<SP>2</SP> also comprising parallel belts is in contact with the upper part m<SP>1</SP> between c and d and as the blanks pass between these points back to the lower felting layer cozing takes place owing to the difference in the speed of the belts of the parts m<SP>1</SP>, m<SP>2</SP>. The feed to the mill is identical to that of the first embodiment.

Title: Binder for forage presses
IPC: A01F15/14
Filed: 1934-05-16
Abstract: 430,205. Baling-presses. LAGAUCHE, H., Bezannes, Marne, France. May 16, 1934, No. 14815. Convention date, June 2, 1933. [Class 94 (i)] [See also Group XXII] Means for holding, twisting, and cutting the wire. used in binding bundles of forage in a press comprise two frames A, B each formed with two limbs provided with notches and given a relative reciprocating movement. After severing the spare wire from one bundle and removing that bundle from the press the frames are left in such position that the free end of the wire is securely gripped thereby. The wire 16, Fig. 10, extends from such free end through the eye of an oscillating needle 24 to a supply reel. The needle is now swung from the dotted line position to that shown in full lines and a fresh bundle is inserted in the machine in the direction of the arrow 25<1>. In swinging the needle the wire is passed between the jaws 13<1>, 14 of a rotary twisting device, Figs. 1 and 4. The needle is now restored to its dotted line position and in so doing again passes the wire between the jaws of the twister and lays it through the recesses 2, 4, 8, 10, Fig. 5, of the limbs of the frames which are now aligned as shown. The twister is then operated and the frame B subsequently moved downwardly thereby severing the wire at the corners of the shoulders 18, 21 of the recesses 2, 4, when these shoulders come into alignment due to the movement of the frame B, and the shoulders 29, 30 of the notches 5, 11 simultaneously release the wire left from the previous tie. The return movement of the frame B forces the wire into an undercut slot 19 of the notch 8 and the shoulder 31 of notch 11 bends the wire along the side of the limb 7 to hold it between the limbs 7 and 9 whilst the needle 24 returns to the full line position ready for the formation of the next bundle and the start of a new cycle.

Abstract: 568,284. Grinding &c. diamonds &c. JEARUM, F. C. Sept. 9, 1943, No. 14826. [Class 60] A machine or attachment for producing, by bruting, grinding and polishing, a cylindrical prism of diamond or other hard minerals, or hard metals, for use as a tool tip or tool piece for turning &c., comprises a mount 1 bevelled at 2 to fit a feed slide to which it is looked by a device 3, and having a projection 4 which may be formed in one with the block or, as shown, secured thereto by screws 8. The part 4 has therein seatings for the conical parts 9 of a hollow mandrel 6 having at its forward end a head 7 comprising an annular chambered portion, and a semicylindrical portion 11 with a diametral narrow face 12 provided with a cavity 13 to receive the diamond 14. On each side of the cavity 13 the face 12 is provided with grooves 15, 15a to receive respectively spindles 16, 17 clamped by plates 18, 19 and formed at their inner ends with conical recesses to form bearings for the conical ends 14a, 14b formed on the diamond ; alternatively, the spindles may be pointed to engage recesses in the diamond. The spindles, or one of them 16, may be spring pressed as by a leaf spring 21 engaging a groove 20 in the spindle and provided with a manipulating piece 22. In a chamber 23 in the head 11 is positioned the head 25 of a spindle 24, mounted in the mandrel 6 to allow rotation of the mandrel, the head 25 carrying a lateral annulus 26 of rubber, leather, &c. adapted to engage the surface of the diamond 14 ; the spindle 24 is adjustable axially by a resilient plunger 30 and screw 29 engaging a lever 27 depending from the spindle, and pivoted at 28 in the mount, and the annulus 26 may be disengaged from the diamond by movement of the lever 27 by a rotatable pin 31 of half-circular or cam section. In order to rotate the diamond and revolve it about the axis of the mandrel 6, the mandrel is driven by bevel gearing 32, 33 driven by a spindle 34, the friction between the diamond and the annulus 26 causing the diamond to rotate on its pivots ; the movement of the diamond in conjunction with the rotation of the cutting-wheel finds automatically the cutting grain of the diamond. The head 7 may be stationary and the spindle 24 rotated, the head being movable to maintain resilient contact of the diamond with the annulus 26. The diamond may be finished by mounting it in a dop and treating its ends to provide flat end planes. Specifications 565,399 and 565,407 are referred to.

Abstract: 1418412 Casting composite articles GREAT CANADIAN OIL SANDS Ltd 28 March 1973 [29 March 1972] 14859/73 Heading B3F [Also in Division E1] A method of hardfacing a metal workpiece 10, e.g. a tooth for a bucketwheel excavator, comprises forming a gap between the surface to be hardfaced and a plate 19 provided with a layer of metallic carbide particles, and filling the gap with molten metal by electroslag welding. Thus a workpiece having a bilaminar hardfacing containing metallic carbide particles on its outer surface is produced. The carbide particles may be dispersed within a glass plate or they may be bound to the surface of a steel plate using sodium silicate as a binder. Suitable carbides include those of W, Si, Cr and Ti. The process conditions are chosen so that the carbide particles do not melt or dissolve in the molten metal during the welding process. Apparatus for carrying out the process comprises a bench 11 for supporting the workpiece 10, a cooled shoe 17, a power supply unit 30 and a control unit 25. Electrode wires 13 pass through a straightening device 20, a feeding device 21 and consumable guide members 15 into the gap between the workpiece and the plate 19.

Hydrocarbons contained in the off-gas may be recovered by washing with diesel oil, and this then stripped and the hydrocarbons returned to the reaction system. The oxygen-containing gas is preferably used in a proportion such that the off-gas after removal of all constituents condensable up to 20 DEG  C. and diesel oil wash contains a maximum of 6% oxygen.
