Title: Electrolytic cavity sinking apparatus and method
IPC: B23H3/00
Filed: 1961-05-25
Abstract: <PICT:0991607/C6-C7/1> In electrolytically penetrating a surface W1 to form a cavity 62 in a workpiece W, electrolyte is forced through a hollow electrode 26 which is moved through an opening 58 in an electrically insulating guide block 56 substantially sealed to the surface.  The electrolyte passes through the electrode and past the work gap and returns through a clearance between the outer surface of the electrode and the inner surface of the opening, the clearance being sufficiently small to ensure that the electrolyte pressure at the gap is sufficient to provide an electrolyte path between the whole area of the electrode front face and the surface even if the surface is irregular or (as shown) is at an angle to the front face of the electrode.  As shown, the electrode is used for making a through bore. A cup 72 is provided at the end of the proposed bore so that, when the electrode has passed through the workpiece, the electrolyte does not escape but is returned through the opening in the guide block. The cup also receives any slug or core removed from the workpiece. The operation is temporarily halted to remove the core.  The electrode 26 may be of copper, has a flanged tip 52 and, behind the tip, is covered with insulation 54 such as a layer of an epoxy paint or resin or a tube made of polytetrafluoroethylene. To prevent lateral vibration of the electrode and short circuiting, the block 56 is provided with guide members 66. Also to prevent short circuiting, an alternative electrode, Fig. 3 (not shown), has its tip made slightly smaller than the insulating sleeve 54. The tip in this case, instead of being a flanged end to a copper tube, comprises a ring-shaped bushing soldered to the tube.  The bushing may be of tungsten, tantalum or a mixture of silver and tantalum. Electrodes made of laminated plates some of which are flat and others of which are corrugated, ribbed or dimpled are also referred to. Specifications 943,101 and 944,613 are referred to.

Title: Improved process for sizing paper, pasteboard and the like
IPC: D21H17/22
Filed: 1920-07-06
Abstract: 147,006. Merckens, W. Dec. 7, 1915, [Convention date]. Sizing; artificial leather.-In sizing pulp in the Hollander, for making paper, pasteboard, &c., size of vegetable or animal origin is allowed to swell in water, melted therein, and partly fixed as a gelatinous mass by treatment with formalin, chrome alum, or other hardening-agent, and as such is comminuted and mixed with the pulp, the washing away of a large quantity of size being thus avoided. The subsequent heating during drying melts the gelatinous size which thus sticks together the fibres. By moistening the product and again treating with formaldehyde vapour or the like, the size is rendered absolutely insoluble and a substitute for sole leather is produced.

Filed: 1949-07-27
Abstract: 659,549. Sausage making. AMERICAN VISCOSE CORPORATION. July 27, 1949, No. 19805. Convention date, Sept. 25, 1948. [Class 28(ii)] Sausage casings 5 filled by a nozzle 4 are linked by squeezing them at spaced intervals between two spaced pairs of opposed teeth 7 on pairs of upper and lower wheels 7 and by rotating or twisting the sausage length lying between the pairs of teeth while held at the squeeze points during rotation. The twisting is done by a yoke or cage of rollers 21, Fig. 4, gripping all around the sausage skin 5, the cage being bodily rotated intermittently in timed relation with the squeeze of the sausage at the spaced points. The twist is applied to alternate sausages in opposite directions of rotation. This intermittent rotation is started by a pin 41 on the first lower wheel 6 engaging a pin 42 on a valve rod 37 which is then moved to the left to admit pressure fluid through a valve 34 to a piston 30 which works an attached yoke 28 which pushes a pin 26 on a gear wheel 25 to rotate it one step. The gear wheel is coupled to rotate the sleeve 18 and cage 17 intermittently through a belt 18 &c. After this twist and when the next linked sausage is intermediate the pairs of spaced squeeze teeth 7, an opposite rotation is given to this sausage by the actuation of the valve rod 37 to the left whereby as explained below the piston 30 is moved to the right with consequent reversed rotation of the sausage gripping rollers 21. This is caused by a pin 51 on the right hand lower roller 6 engaging under a cam surface 50 of a latch 45 so pivoting it clockwise about 46, and releasing 44 from 43 so that spring 39 can slide the valve rod 37 to the right to admit pressure fluid to the left side of the piston 30 to move it as above. The freely mounted rollers 21 inside the rotated sleeve 18 hold the individual sausage after twisting. Further holding is done by the set of idler rollers 52 at the exit.
