Abstract: 959,323. Sawing. E. A. HAYDEN. June 5, 1961 [Jan. 10, 1961], No. 20142/61. Heading B5L. A portable log saw assembly comprises an inverted substantially U- shaped frame having a tie-rod 230, Fig. 2, from the ends of which depend leg portions 208, 210, having elongated bars 242, 244 slidable thereon, and a plurality of rollers mounted for rotation between its bars, the rollers including leading and trailing rollers 258, 262 and at least one intermediate roller 268 normally coplanar therewith but releasable out of coplanar relationship. The rollers support the assembly on a log which a chain saw driven by means S about a bar 238 cuts the log in a plane below the rollers as described in Specification 963,425. The bars 242, 244 are adjustable relative to the bar by screw-and-nut mechanisms 252 to determine the thickness of a board to be cut from the log. The intermediate roller 268 is eccentrically mounted in the bars and its axis is movable out of coplanar relation with leading and trailing rollers by levers 286, 288. The assembly is laterally guided during sawing by rollers 314, 316 mounted on a bar secured to the foot 236 of one of the leg portions, the rollers 316 beneath the saw bar being screwthreaded to act on the log as the assembly is moved along the log during sawing to pull the assembly into contact with the log. In operation, during initial engagement of the saw with the log, the intermediate roller 268 is locked in coplanar relation with the leading and trailing rollers and the assembly supported on the log by the leading and intermediate rollers 258, 268. When the saw has engaged the log sufficiently for the trailing roller 262 also to support the assembly, the intermediate roller is raised by the levers out of coplanar relationship. Towards the end of the cut, the intermediate roller 268 is returned to its coplanar position and the assembly is supported by the intermediate and trailing rollers.

Title: Improved manufacture of an ammonium potassium phosphatic fertilizer and of a utilisable slag
IPC: C05B13/02
Filed: 1930-07-04
Abstract: Calcium and potassium phosphates; phosphoric acid; ammonium phosphate; phosphorus; silicates.--In obtaining an ammonium potassium phosphatic manure, a mixture of silico-aluminous potassium rocks such as felspar or leucite, crude calcium phosphate, lime, and coal is moistened and agglomerated in steam in an autoclave at 180 DEG  C., and heated in a shaft or electric furnace, the amount of coal added being smaller in the latter case.  The proportions are such that for each molecule of potash, two molecules of phosphoric anhydride are present.  When a shaft furnace is employed, the air injected is heated to 400-600 DEG  C. in a preheater of iron or pottery.  A slag, capable of yielding cement, and containing 50 per cent CaO, 20 per cent Al2O3, and 30 per cent SiO2 is obtained, an is run into water. When employing an electric furnace vapours of phosphorus and potash are evolved and are burnt.  In the case where a shaft furnace is used, the phosphorus is oxidized by the carbon monoxide and steam present.  The vapours of phosphoric anhydride and potash are absorbed in an atomizer, the concentration of the solution being maintained at about 50 DEG  B<\>ae. The residual gases may be used for heating purposes.  The solution of dipotassium phosphate and phosphoric acid is treated with crude calcium phosphate, forming monocalcium phosphate, and gaseous ammonia and ammonium sulphate are then added. The resultant mixture of dipotassium phosphate, diammonium phosphate and gypsum is allowed to set in a tank, extracted, and dried at 100 DEG  C.ALSO:In obtaining an ammonium potassium phosphatic manure, a mixture of silico-aluminous potassium rocks such as felspar or leucite, crude calcium phosphate, lime and coal is moistened and agglomerated in steam in an autoclave at 180 DEG  C., and heated in a shaft or electric furnace, the amount of coal added being smaller in the latter case.

Title: Improvements in or relating to storage battery systems
IPC: H02J7/14
Filed: 1922-07-31
Abstract: 207,578. White, A. E., (Cellokay Manufacturing Corporation). July 31, 1922. Testing storage batteries; casings for instrumonts.-The charge conditions of the batteries in storage battery systems is indicated by means of a record or testing circuit adapted to discharge the batteries momentarily at a rate greater than the normal or rated current of the batteries, preferablv at a rate from 1.5 to 7 times the rated current, an indicator being provided to measure a characteristic of the discharge and so give a rapid reliable indication of the battery condition whether the normal working circuit is open or closed. The testing circuit may comprise a testing resistance unaffected by temperature changes, for example, a German silver wire, or may include the coil of the indicator or the normal load. A galvanometer in series with, or a voltmeter in shunt with, the testing resistance and with a testing switch may be used to measure a characteristic of the discharge. In an automobile starting and lighting system of the kind in which the motor-generator set MG, Fig. 2, charges the batteries 1, the voltmeter 15 normally indicating the battery voltage is used to indicate also the battery condition by shunting it with a testing load 5 and switch 6, the voltmeter 15 having the usual voltage scale 16, Fig. 3, and a battery charge scale 19. As the full variation in battery charge condition corresponds to a variation of .2 volts per cell on the scale 16, a " suppressed " scale 16 not indicating voltages below a certain minimum is used for the normal measurement of the voltage of the batteries, the scale 19 being thus enlarged. The switch 6 and voltmeter 15 are mounted together on the main instrument board 18 of the vehicle and the switch 6 may comprise a push-button 17 in the voltmeter frame.

Title: An improved method for the production of sheet rubber, gutta-percha, balata, and other analogous vegetable resins and fabrics coated therewith
Filed: 1927-08-12
Abstract: 302,201. Dunlop Rubber Co., Ltd., Twiss, D. F., and Murphy, E. A. Aug. 12,1927. Latex, coagulating ; indiarubber, guttapercha, and balata sheets, threads, and tapes ; composifions containing indiarubber.-A process for coating fabrics with rubber and the like and for making rubber sheeting, strips, &c. consists in applying by spreading a concentrated or a compounded concentrated unvulcanized rubber latex in the form of a cream to a moving surface and causing the cream by the action of heat to set or gel as quickly as possible, the setting in the case of coated fabrics occurring before the water in the dispersion penetrates the fabric to any substantial extent. A concentrated compounded latex as described in Specification 290,313 or a latex concentrated by centrifuging as described in Specification 219,635 is suitable. In addition to the usual compounding ingredients, substances such as factice, rubber waste, rubber reclaim, mineral rubber, synthetic rubber, leather dust, cork dust, fibres metal dust, colloidal metals and synthetic resins may be added. In an example, for coating artificial silk, the cream is poured on the fabric and spread thereon by a blade, the least possible pressure being applied. The fabric is immediately passed over a heated table so that the dispersion sets before the water has penetrated the fabric. The fabric is then either returned to receive a fresh coating, or is led into a curing chamber. The spread deposit can be set by passage through a heated setting and dehydrating bath described in Specification 303,544. In the case of sheeting, the backing may be a smooth surface to impart a gloss, and may have an engraved pattern which will be imparted to the rubber face. Tapes or threads may be obtained by having suitable indentations in the spreading blade. When powerful accelerators are used, the latex cream may b.e applied to the backing in two layers, one containing the sulphur and the other the accelerator. Alternate layers may also be applied to secure special effects such as of colour.
