Title: Improvements in or relating to the manufacture of split poles or rods of bamboo or similar material
IPC: B27K3/15
Filed: 1947-04-03
Abstract: The method of impregnating bamboo and similar material, as described in the parent Specification is modified by dispensing with the initial soaking of the rods or rod sections in "Bakelite" (Registered Trade Mark) free water.  In one modification the rods or rod sections after being cemented together and cleaned are placed directly into a bath of solution comprising two parts of Bakelite resin and one part water at a temperature of 60 DEG F. to 70 DEG F.  This bath is maintained at this temperature for two to three days then raised quickly to 100 DEG F., maintained for three hours and then quickly restored to room temperature.  This is repeated for several days, then the bath is raised to about 125 DEG F. and maintained for an hour before the temperature is restored to normal.  The rods are then air dried and then heat treated in an oven.  In a variation, the initial bath solution contains equal parts of Bakelite and water.

Title: Improvements in or relating to safety devices for the driving turbines of vehicles
IPC: B60T7/12
Filed: 1952-04-09
Abstract: 742,984. Fluid-pressure brakes. REGIE NATIONALE DES USINES RENAULT. April 9, 1952 [June 20, 1951], No. 9148/52. Class 103 (1). [Also in Groups XXIX and XXXI] A turbine-driven vehicle having a compressed air or vacuum brake system is provided with a device, adapted to prevent the turbine racing, the device comprising a rod 3 movable under the influence of turbine speed and connected to a valve 75, 86 or 95 in the brake system, whereby at a predetermined turbine speed the brake is applied, the brake being either released automatically on a drop in turbine speed or remaining engaged until released by the driver. As shown in Fig. 1 the invention is applied to a compressed air or vacuum disengaged brake system in which the brakes are applied by connecting a pipe 74 through the valve 75 to atmosphere, the valve 75 housing a piston 76 connected to the rod 3 so that, when the turbine reaches the predetermined speed, movement of the rod causes the piston 76 to connect the pipe 74 to atmosphere, the brakes remaining applied until the turbine speed drops. In a modification, Fig. 2 (not shown), the invention is applied in a similar manner to a braking system in which the brakes are applied by being connected to a vacuum or compressed air reservoir. In another modification, Fig. 3 (not shown), the pipe is placed in communication with atmosphere through an electromagnetic valve which is controlled by a switch operated by the movable rod. This modification may be applied, Fig. 4 (not shown), to the braking system employed in Fig. 2 (not shown). The braking systems in Figs. 1 and 2 may have incorporated in them a mechanism, Figs. 5 and 6, (not shown), by which the brakes remain applied after the turbine speed drops and are released by the driver. In another embodiment, Fig. 7, the valve 86 is electromagnetically operable to connect a pipe 85 to atmosphere, the valve being operative when a switch 89 is closed. The switch 89 and switches 90, 93, 94 are closed by energization of a relay 88, such energization being effected by a switch 87 under the control of the rod 3. The switches 93, 94 are effective to operate an electrically-energized signal and the disengagement of a clutch forming part of the vehicle transmission when the turbine speed is excessive. The switch 90 maintains the relay 88 energized despite subsequent opening of the switch 87 as the turbine speed drops, and thus maintaining the brakes applied, the drive disengaged and the signal energized until manual opening of a switch 92. The valve 86 may be replaced by the valve 95 which applies the brakes by connecting the system to a compressed air or vacuum reservoir.

Title: Process and apparatus for treating electrolytically tinned ferrous metal strip
IPC: C25D5/50
Filed: 1947-04-03
Abstract: 631,687. Tinning. CARNEGIE-ILLINOIS STEEL CORPORATION. April 3, 1947. No. 9163. Convention date, April 23, 1946. [Class 82(ii)] [Also in Group XXXVI] Electrolytically tinned strip metal is sprayed on both sides with a coating of thermally stable vegetable oil such as palm or cotton seed oil, the excess oil being removed leaving a film adhering to the strip which is then passed through a thermally insulated muffle, the portion of the strip within the muffle being heated by the passage of electric current therethrough to a temperature sufficient to melt the tin before it leaves the muffle from which the strip is immediately passed through a quenching bath. As shown, the tin coated strip 1 is passed through a steam drier 8 to dry off any liquid adhering thereto and thence upwardly between nozzles 17 which spray oil supplied from reservoir 18 by pump 19 on to both sides of the strip. Excess oil flowing down the strip is wiped by pinch rolls 16 and delivered into trough 25 for return to reservoir 18. Additional pinch rolls 16a may be provided to remove any excess oil adhering to the strip after passage between the nozzles 17. The oil coated strip then passes upwardly into the refractory muffle 27 divided by inner refractory wall, 28 dividing the muffle into leg 29 in which the strip is heated from room temperature to the melting point of tin by electric current passed through the strip between contact rolls 11 and 33 and leg 30 in which the tin coating is melted starting at the top of the leg. From the muffile the strip passes immediately into a quenching bath 34. The muffle is heated by resistance elements 31 in the walls thereof to prevent loss of heat from the strip by radiation. The strip is maintained at a temperature above the melting point of the tin for such length of time as to promote an alloy bond between the tin and the strip metal and pin holes in the tin coating are substantially filled. Specification 557,029, [Group XXXVI], is referred to.

Title: Preparation of esters of aromatic acids
IPC: C07C51/265
Filed: 1961-03-14
Abstract: An alkyl ester of an aromatic carboxylic acid is obtained by introducing a gas containing molecular oxygen into a reaction zone containing a liquid mixture of an alkyl aromatic hydrocarbon and an alkyl ester of an aliphatic carboxylic acid, together with an oxidation catalyst dissolved in the mixture, maintaining the reaction zone at 150-300 DEG C. and under a pressure sufficient to maintain at least 1.25 mole equivalents of the alkyl ester per alkyl group of the alkyl aromatic hydrocarbon in the liquid phase, and withdrawing the oxidised mixture from the reaction zone.  The process is particularly applicable to the production of dimethyl terephthalate from p-xylene. Toluene and durene are examples of other alkyl aromatic hydrocarbons which may be used, and methyl acetate, formate, propionate, 3.5.6- trichloroperfluoro-hexanoate, and perfluoroacetate, and dimethyl oxalate and perfluoroglutarate, are examples of alkyl esters.  Ethyl, propyl, or butyl esters may also be used.  Some free carboxylic acid may be present and in the case of a perhalogenated acid it may serve as catalyst or catalyst promoter of the oxidation.  Oxides, hydroxides, inorganic and organic acid salts of cobalt, lead, manganese, chromium, iron, cerium, and vanadium may be used as oxidation catalyst.  In an example, p-xylene is oxidised with air in an autoclave in the presence of cobalt naphthenate and in the presence of methyl acetate.  The reaction product contains dimethyl terephthalate, methyl hydrogen terephthalate, terephthalic acid, methyl p-toluate, and p-toluic acid.  Unreacted and partially reacted material may be returned to the reaction vessel.  Free aliphatic acid is preferably re-esterified before returning the residual liquor to the reaction zone.

Abstract: 526,653. Fractional condensation. BRITISH OXYGEN CO., Ltd., and SCHUFTAN, P. M. March 24, 1939, No. 9282. [Class 32] [Also in Group XXVIII] A gaseous mixture, the constituents of which are mutually soluble in the liquid state, is split up by passage through a regenerator precooled so that initially all the less volatile constituents and a substantial proportion of the more volatile are condensed in the regenerator, the passage of gas being continued till the more volatile constituents are driven off ; the remaining less volatile constituents are then removed e.g. by revaporization under reduced pressure or by continuing the supply of mixture, the less volatile constituents being in the latter case recovered in an impure state. The constituents to be separated may be diluted in the original mixture with more volatile substances e.g. ethylene and propylene may be separately recovered from coke-oven or oil refinery gas. The process may be applied to mixtures of oxygen and nitrogen, water and alcohol, or water and ammonia.
