Title: Chloride free leaching process for porous zinc anodes
IPC: H01M4/02
Filed: 1972-02-09
Abstract: 1341928 Amalgamated Zn battery anodes P R MALLORY & CO Inc 9 Feb 1972 [10 Feb 1971] 6122/72 Heading C7D [Also in Division H1] A battery anode is made by mixing Zn powder, mercuric oxide powder and a chloride-free filler material and dissolving out the filler material with a chloride-free acid leachant to leave a porous amalgamated chloride-free Zn anode which has a lowered tendency to anode gassing. In example, the powder mix is pressed to make green anodes prior to leaching. The leachant may be acetic, oxalic or boric acid and the filler is preferably the corresponding sodium salt. The product may be washed with de-ionized water until the effluent has a pH of at least 6, washed with alcohol and dried (e.g. in air). The product amalgam contains trace amounts (e.g. up to 1%) of inert chloride-free (e.g. acetate, borate or oxalate) ions integrally united at specific lattice sites to reduce anode gassing.

Title: Improvements in pleating machines
IPC: C23C18/52
Filed: 1928-02-28
Abstract: 303,127. Ezbelent Fils. Dec. 30, 1927, [Convention date]. Pleating.-In. pleating-machines in which upper and lower knives are pivotally mounted on an axle and reciprocated to and from the pleatsetting rolls, a positively-driven member actuates the knife carrier to move it toward one of the rolls and spring- actuated means resists said motion and urges the carrier towards the other roll. The knives are relieved from the action of the positively-driven member by means which may comprise a spring catch or locking device. As shown, knives 1, 2 carried by cheeks 3 are pivoted at 6 and moved by means of a pin or rod 9, mounted on a plate 10, pivoted at 11 and are moved against an upper forming plate 7 or a lower forming plate 8, according as it is desired to have overlapped or underlapped pleats. The plate 10 is oscillated by means of a spring-pressed lever 15, roller 20, and cam 21, adjustment being obtained by a slot 18 and slide block 17. The cam 21 is provided with a part a, d, c which corresponds to the lower position of the knives and it may also be a rearward movement of same, and is provided with a part a, b, c corresponding to the upper position and forward movement. An intermittently-rotated cam 28 or series of cams, which may have a series of removable bosses as in the machine of Specification 267,873, operates or not on a roller 27 carried on a lever pivoted at 23 and having one end 22 serving as a hook to engage a catch 24 on the lever 15. The hook holds the lever in the position for constantly producing underlapping pleats, and when the hook is released the machine will produce overlapping pleats. By inverting the respective positions of the pivot point 11 and sliding member 17, the hook acts on the projection 24 to produce overlapping pleats. In Fig. 2 is shown a. series of cams 28 - - 31 with bosses for engagement by the roller 27, said cams being slidable axially by means of a sleeve 26 and handle 33. Notches 35 - - 38 correspond to positions of the cams for engaging the roller 27 and a lower notch 35<1> to a position in which the hook 22 engages the catch 24. Raised portions 40, corresponding to a slight rotation of the sleeve 26, bring the roller out of engagement with the cams as it passes from one to the other.

Abstract: 158,159. Marks, E. C. R., (Gilbert & Barker Manufacturing Co.). March 1, 1920. Air and steam pressure sprayers; nozzles with several outlets.-A liquid-fuel burner comprises a body 10 and a cap 11 between which are clamped a number of removable plates 17, 18, alternate plates being slotted to form nozzles. The body 10 has an inlet passage 13 for the atomizing fluid which may be air or steam, and a fuel inlet passage 14. The nozzle-forming plates 17, which are reversible, have a recess 23 which communicates with either of the inlet-passages 13 or 14, according to which face is uppermost, and a hole 22 which registers with the opposite inlet-passage. The blank plates 18, which are placed between the nozzle-forming plates, have holes 20, 21 which register with both inlet-passages. Both sets of plates have holes 19 through which the clamping-bolts 12 pass. The burner, when assembled as at Fig. 2, has a series of nozzles, the air or steam nozzles 24 occuring between the fuel nozzles 25. The cap and body are standardized, but the plates, which may be of different thickness and have different sizes of recess, are readily interchangeable so that a burner may be built up to suit any conditions.
