Title: Improvements in and relating to the removal of liquid from peat, coal-mud or like watery substances
IPC: C10F5/00
Filed: 1929-01-19
Abstract: 304,329. Ten Bosch, A. Jan. 19, 1928, [Convention date]. Peat, preparing. - Peat, coal-mud or other watery substances from which water is to be expressed are subjected to a perforating process and the increased surface thus formed is rendered permeable to water by heat, electrical or other action. According to one method the peat is passed between perforating rollers included in an electric circuit, so that the current passing between contiguous opposed pins on the rollers heats the material around the perforations made by the pins. The surface layers may alternatively be broken down by chemical treatment or in a further method the peat may be squeezed between steam-heated perforating plungers of a heated press. According to the Specification as open to inspection under Sect. 91(3) (a) the colloidal condition of the peat surface may be disrupted by electric osmosis through the use of alternating current, the peat acting as a rectifier. This subject-matter does not appear in the Specification as accepted.

Title: Method of preparing preliminary metal or steel from pig iron containing phosphorus
IPC: C21C5/32
Filed: 1958-01-22
Abstract: A method of producing steel or preliminary metal from pig iron containing 0.1 to 2% phosphorous by blowing oxygen containing gas on to the surface of a slag layer to oxidize FeO to Fe2O3 which is reduced at the slag - metal interface comprises carrying out the process in a refining vessel having a capacity of at least 1.3 cu. m. per metric ton of pig iron and having a depth of metal not exceeding 40 cms.  The slag may be treated by the addition of lime or soda to reduce the surface tension or borax or fluorides to increase the surface tension. When steel is being prduced after the phosphorous has been removed the metal may be heated by a burner flame and the Fe2O3 in the slag allowed to remove carbon remaining in the metal, but oxygen may be added if necessary to increase the Fe2O3 in the slag.  The phosphorous slag is not removed until the greater part of the Fe2O3 has been reduced.  Superheated steam may be added at the beginning of the blow in the proportion of steam to oxygen of 1:2 to 1.4 and the steam is not used for more than 25% of the total time of blowing. The process may be performed in a vessel which may be rotated about its horizontal or vertical axis.

Title: Bleached sugar cane wax esters and amides for use in polishes and the production of said esters and amides
IPC: C11B11/00
Filed: 1954-01-28
Abstract: Bleached cane-sugar wax (mainly fatty acids) is converted into certain poly-esters or bis-amides.  The poly-esters are prepared from ethylene glycol, propylene glycol, trimethylene glycol, glycerol or penta erythritol by esterification with the bleached wax, suitably by heating in the presence of an esterification catalyst and under reduced pressure, in the case of the less volatile polyhydric alcohols, to remove the water formed.  The bis-amides are prepared either by condensing the bleached wax with a polymethylene diamine to form polymethylene bis-amides or by amidification of the wax to the corresponding carboxy-amides RCO.NH2 which are then condensed with formaldehyde to form methylene bis-amides of the bleached wax.  The poly-esters and bis-amides are waxes suitable for use in polishes (see Group III). In examples: (1) bleached vacuum refined or unrefined cane-sugar wax and penta erythritol; or (2) the refined wax and ethylene glycol are heated together in the presence of p-toluene sulphonic acid and water of esterification is removed under reduced pressure until the product has an acid value of 16-17; (3) the bleached wax is heated at 200-215 DEG  C. with ethylene diamine; or (4) hexamethylene diamine yielding the ethylene or hexamethylene bis-amide of the wax, acid value 5-12; (5) the bleached wax is reacted with excess thionyl chloride, the product is reacted in carbon tetrachloride with excess NH3, the amide formed is reacted with formaldehyde in alkaline alcoholic solution and the N-methylol derivative so formed is isolated and treated with dilute H2SO4 to yield the methylene bis-amide of the wax.  Specification 475,170, [Group IV], and U.S.A. Specification 2,477,346 are referred to.ALSO:Wax polishes comprise methylene or polymethylene bis amides of bleached cane sugar wax and/or polyesters of the bleached wax prepared from ethylene glycol, trimethylene glycol, propylene glycol, glycerol or pentaerythritol.  The poly-esters and bis-amides may be blended together in controlled amounts to give various gel strengths and flow-points as desired.  Dyes may be incorporated in the polishes.  Some specified polishes comprise paraffin wax, turpentine or white spirit and the pentaerythrityl ester, ethylene glycol ester, ethylene bis-amide, methylene bis-amide or hexamethylene bis-amide of the bleached cane sugar wax.  Other polishes comprise paraffin wax, turpentine and mixtures of the wax pentaerythrityl ester and the methylene or ethylene bis-amide of the wax in various proportions as shown in a graph.  The preparation of the esters and amides is given (see Group IV(b)).  Specification 475,170 [Group IV] and U.S.A. Specification 2,477,346 are referred to.

Title: Improvements in variable-speed and reversing gearing
IPC: F16H61/02
Filed: 1931-01-27
Abstract: 361,718. Variable-speed reversing gearing. NORDENSWAN, G. V., Appelviken, Stockholm. Jan. 27, 1931, No. 2693. Convention date, Jan. 27, 1930. [Class 80 (ii).] In variable-speed epicyclic gearing for motor cycles, cars, &c., the ratio varies inversely with the load, while the power-transmitting capacity varies with the speed of the driving shaft, these effects being produced by interconnecting two members of the gear by a centrifugal clutch, for example of the kind in which vanes on a driving member rotate in a driven casing containing powder, balls, or the like. Epicyclic or non-epicyclic means for effecting reversal may be provided. A clutch 11, 12, Fig. 1, of the kind described is provided between the driving shaft 10 and a drum 13 carrying an annulus 16 engaging planet wheels 17 on a carrier 19 secured to the driven shaft 20, which planet wheels are engaged also by a sun-wheel 15 secured to the shaft 10. By application of a brake 14 to the casing 12, a reduced non-variable forward drive is obtained. In a modification, the part 19 is free, but may be clutched to the driven shaft for automatically varying forward drive, or alternatively may be braked, when, upon the drum 13 being clutched to the driven shaft, a non-epicyclic reverse drive is obtained. Automatic or manual means may be provided to turn the clutch vanes upon their axes or to draw them towards the clutch centre to reduce or stop the transmission of power between its parts, or a separate clutch, for example of such vane or other centrifugal type, may be employed to disconnect the transmission, such clutch being capable of transmitting the full torque without slip. As shown in Fig. 2, a reverse drive may be obtained by securing to the wheels 17 smaller wheels 21 engaging a loose sun wheel 22 which may be braked by a band 24. Fig. 4 shows a modification in which an additional clutch 30, 31 is provided in the driving shaft 10 and the drum 13 is splined upon the clutch casing 12 so that, for reverse, the annulus 16 may be disengaged from the wheels 21 and connected to the framing by a positive brake 38 at the same time that a wheel 34 thereon is engaged with the wheels 21. With the parts placed as shown, backward rotation of the casing 13 is prevented by a detent 35, 36, which ensures that the forward automatically adjusted speed of the driven shaft 20 cannot fall below that obtainable when the casing 13 is stationary. The wheel 34 may be replaced by a slidable wheel loose on the driven shaft and connected to the framing by a detent preventing its forward running.
