Abstract: 331,567. Marks, Sir G. C., (Bauer Bros. Co.). March 5, 1929. Disc and like mills; reducing wood.-A method of producing pulp from wood &c. consists in disintegrating water-impregnated material, and then in the presence of water subjecting it to a rolling and crushing or squeezing action of two oppositely and concentrically positioned plates or discs between which relative rotary movement at high speed is produced. The material is fed from a hopper 1 through a feeding device 2 to a disintegrating machine 3 supplied with water from a pipe 6, the material being discharged into a conveyer 7 and fed therefrom into a secondary apparatus 8. The disintegrating machine 3 may consist of rollers which reduce the material and impregnate it with water. Heat in the form of steam or hot water may be furnished to the disintegrator. The disintegrator 3 comprises opposed discs of which one or both rotate, the disintegrating surfaces 3<1>, Figs. 3 and 4, being formed with a series of concentric corrugations which interengage and which are provided with radially extending ribs 15. The material is fed in the centre of the discs and the space between opposed corrugations is such that the tortuous nature of each channel increases and the crosssectional dimension decreases from the central throat to the outer discharge end. The secondary apparatus comprises oppositely rotating discs 9, 10 provided with radial disintegrating ribs 19, Fig. 10, inclined from base to point in the general direction of rotation. If the process of pulping is to be completed in the secondary apparatus further teeth 20, Fig. 6, of cpposite inclination to the teeth 19, are provided in rows extending to the periphery of the disc. These teeth roll, press and rub the material without cutting in the presence of water from a pipe 6 or hot water or steam from a pipe 7,Fig. 2, and the material is discharged through the outlet 18. Water for cleaning the discs 9, 10, Fig. 2, may be supplied by a pipe 22. The number of rows of these different forms of teeth may be varied.

[Class 31 (ii)] A machine for producing records on statistical cards is provided with means for displacing the card laterally to one of two or more positions combined with means acting freely on the rear edge of the card to push it step by step under a set of record - forming elements. The invention is shown as applied to a machine for punching sterling money amounts having eleven keys 6 which operate six punches 3, the even numbers being represented by a single punch and the odd numbers by the next higher even number punch together with the number 11 punch. A card is fed step by step under the punches by a carriage 21 which has escapement mechanism and a pusher 22 for freely engaging the rear edge of the card. A spring finger 23 may engage over the front edge of the card. The card is moved laterally to bring another part thereof under the punches by parallel bars 8, 8<a> which are moved by pinions 11 co-operating with racks 10 fixed to the bars; the pinions are coupled to a handle shaft 12 by loosely engaging dogs 14, 15 which allow limited independent adjustment of the ends of the bars 8, 8<a> to abut against adjustable cam stops 9 under the action of springs which act on the pinions 11 and are movable over a dead centre. Depression of an even number key rocks a lever 5a which by a lug 32 co-operating with a lever 4 actuates the corresponding punch 3. Depression of the next lower odd number key rocks a lever 5b which by a projecting pin 33 cooperating with the lever 4 lowers the same punch 3 and by a pin 27 co-operating with a collar 26 on a shaft 24 rocks the latter so as to lower the number 11 punch by the interaction of an arm 25 on the shaft with a lever 4<a>. To render the " touch " of all the keys the same, the levers 5a, 5b being of different length, the projections 27, 32 are differently positioned, and stronger return springs are provided for the keys actuating only one punch. The machine may be modified for decimal amounts by omitting the number 11 punch and replacing it by a number 9 punch. Instead of punches, record-forming elements may be provided to print spots.

Abstract: 1,164,081. Lifting magnets. L. FRITZ. 16 Feb., 1968 [21 Feb., 1967], No. 7662/68. Heading H1P. In a lifting electromagnet a part of the energizing coil which does not magnetically bridge the poles of the magnetic circuit is made of ferromagnetic material. As shown, Fig. 3, a section 18 of the coil of a pot-type magnet is wound from an insulated ferromagnetic conductor to increase the effective size of the polepiece 15. The remaining section 19 of the coil is wound from insulated copper or aluminium wire. In a modification, Fig. 4 (not shown), the ferromagnetic winding is arranged on three sides of the cross-section of the winding adjacent to the magnetic circuit members. The ferromagnetic winding may comprise an uninsulated strip of steel interleaved with a strip of anodized aluminium to insulate the turns from one another, Fig. 6 (not shown). The aluminium strip may be connected in parallel with the steel strip to increase the conductance of the winding. The ferromagnetic coil section may act as a choke in a protection system, Fig. 7 (not shown). The two sections of the coil are connected, over insulating switches (37, 38), in parallel to a power supply, and a varistor (36) is connected in parallel with the ferromagnetic coil section (35). The magnet is deenergized by opening the supply to the ferromagnetic coil section before that to the non- ferromagnetic coil section so that voltage surges due to the inductance of the windings is dissipated in the varistor. The invention may also be applied to horseshoetype magnets Fig. 5 (not shown).
