Filed: 1951-08-31
Abstract: The invention comprises 6 : 61-alkylidene bis-(2-isobornyl-4-methyl phenols), e.g. 6 : 61-methylene bis-(2-isobornyl-4-methyl phenol) <FORM:0687833/IV (b)/1> which may be prepared by reacting camphene with p-cresol in the presence of a Friedel-Crafts catalyst, to give a monobornyl p-cresol and reacting this with an aldehyde in the presence of an acidic or basic compound as a catalyst to give the desired diphenylol compound.  Suitable aldehydes are formaldehyde, butyraldehyde and heptaldehyde.  In an example, p-cresol is reacted with camphene in the presence of boron fluoride etherate to give mono-isobornyl-p-cresol which is separated by distillation and reacted with formaldehyde in the presence of a further quantity of boron fluoride etherate to give 6 : 61-methylene bis-(2-isobornyl phenol).  The products are used as antioxidants.ALSO:The 6 : 61 alkylidene-bis-(2-isobornyl-4-methyl phenols), e.g. 6 : 61-methylene-bis-(2-isobornyl-4-methyl-phenol), <FORM:0687833/III/1> (see Group IV (b) for preparation) may be used as antioxidants in gasoline or fats.  The methylene bridge in the specified compound may be replaced for example by a butylidene or heptylidene group.ALSO:The 6 : 61 alkylidene bis-(2-isobornyl-4-methyl phenols) e.g. 6 : 61-methylene bis-(2-isobornyl-4-methyl phenol <FORM:0687833/V/1> (see Group IV (b) for preparation) are used as antioxidants in natural or synthetic rubber or allied unsaturated gums.

Abstract: <PICT:0969387/C1/1> Niobium pentachloride is produced by simultaneously feeding to a reaction zone maintained at a temperature between 300 DEG  and 650 DEG  C. and containing activated carbon, a niobium-bearing oxidic material and Cl2, Cl2+CO, COCl2 or Cl2+COCl2\sBCO, such that the amount of chlorine is at least sufficient to convert all the niobium to pentachloride. Activated carbon of surface area 500 m.2/gm. or above and preferably of cellulosic origin, e.g. wood or nut charcoal, is charged into a closed reactor 1 and fluidized by an inert gas, e.g. N2.  The reactor may be of silica, silica brick, nickel or a nickel alloy. Electrical or other heating is applied externally to raise the bed to the operating temperature. The oxidic niobium material, e.g. columbite or pyrochlore concentrate and chlorinating gas to replace the inert gas are supplied simultaneously through 4, 2.  NbCl5, together with any chlorides of Mn, Ca, Si or Ba, leave through outlet 3, ensuring that the entering ore cannot contaminate the product.  An excess of 10-50% chlorine above that stoichiometrically required to react with all chlorinatable values in the ore is used.  95% or more NbCl5 is separated from the product.

Abstract: 1,273,524. Moulding shoes. PORVAIR Ltd. 30 April, 1969 [1 May, 1968], No. 20737/68. Heading B5A. [Also in Division A3] Water vapour permeable, flexible, microporous three dimensionally shaped shoe uppers or upper components having resistance to loss of shape when heated are made by dip moulding a former into a mixture of a polymer extended in a liquid vehicle, e.g., a solvent, and coagulating the layer of polymer formed upon the former by a non-solvent for the polymer. The uniformity and size of the pores may be enhanced by incorporating removable particles of a filler, e.g., salt, in the extended polymer and removing the filler subsequently by means of the non-solvent, e.g., water, in the case of a salt filler. The non-solvent may contain a dye to be transferred into the dip moulded layer to colour it during the coagulating step. In one embodiment multi-layered polyurethane shoe uppers are made by dipping a hollow sintered polyethylene former into successive salt containing polymer mixtures, the former being covered with a reinforcing sock or toe reinforcement if desired. The former is withdrawn at different speeds to give regions of differing thickness if desired and the non-solvent may be applied by dipping in a bath, passing it into the interior of a hollow porous former, or both. The former may be made of wood, metal, for example wire gauge, solid or sintered plastics, or fabric and is internally supported if necessary. Where hollow, the interior of the former is preferably vented by a tube to the atmosphere to promote adhesion of the material to core.

Title: Electrical translator devices
IPC: H01L29/00
Filed: 1958-07-01
Abstract: 863,829. Semi-conductor circuits. SYLVANIA ELECTRIC PRODUCTS Inc. July 1, 1958 [July 8, 1957], No. 21085/58. Class 40(6) [Also in Group XXXVI] In a semi-conductor arrangement comprising a body of semi-conductor including a first region of one type conductivity and second and third regions of the opposite conductivity type, with a corresponding ohmic connection to each region, the junction between the first and second regions is reverse biased below the breakdown voltage. Electromagnetic means which normally deflect minority carriers injected at the third connection towards the first connection operate in response to the avalanche breakdown current across the aforesaid junction initiated by triggering means to deflect the carriers towards the second connection for the purpose of maintaining the breakdown current. Operation of the switching circuit shown in Fig. 1, incorporating the semiconductor device illustrated in Fig. 2, is as follows: Initially holes flow from P region 3 to electrode 7 under the influence of the magnetic field, and the PN junction 4, 2 is reverse biased to slightly below its breakdown voltage. When a positive pulse is applied from source 17 part of the increased injected hole current drifts into the space charge region of the junction and produces avalanche breakdown. The resulting voltage developed across load 11 reduces the current in the magnet winding to produce a further increase in current through the load. The cumulative effect is a reversal of the field and consequent cutting off of the current to electrode 7. The circuit is re-set by applying a negative pulse at electrode 5 when the above process is reversed. In an alternative circuit (Fig. 2) switching is effected by current pulses applied to an auxiliary winding on the electromagnet core. In this case the holes initially enter the space charge region as a result of deflection in the modified magnetic field. The circuit of Fig. 1 may be modified to act as an oscillator by replacing pulse source 17 by a capacitor shunting resistor 15 and battery 16, the frequency of oscillation then being determined by the time constant CR of the capacitor and resistor.

Title: Improvements in the treatment of cellulosic materials and the manufacture of cellulose esters and ethers therefrom
IPC: D21C3/26
Filed: 1932-07-27
Abstract: Ligno-cellulosic materials such as wood, esparto, grasses, and also wood pulps from which the lignins have already been partially removed by the customary commercial process, for example, the sulphite, soda, or sulphate process, are subjected to treatment with alkali, especially dilute alkali, at high temperatures, to remove or substantially remove the lignins, and then heated with an acid liquor containing sulphur dioxide either in the free state or in the form of a bisulphite, or in both forms.  The alkali may be employed in concentration under 5 per cent, e.g. 3 per cent and under pressure of, e.g. 7 to 10 atmospheres, at temperatures of 100 to 180 DEG  C., preferably 130 to 145 DEG  C.  The treatment with the sulphur dioxide may be carried out at temperatures of 100 to 140 DEG  C., and under pressure.  The sulphur dioxide may be used alone, or it may be wholly or partly combined in the form of bisulphite, with soda, potash, lime, magnesia and the like.  When used for the production of cellulose derivatives, the cellulose may be pretreated, for example, by means of lower aliphatic acids, in the liquid, dissolved, or vapour state, as described in Specification 263,938, [Class 2 (ii)]. The treatment with aliphatic acid may be combined with the sulphiting step of the present invention.  The cellulose may be esterified so that the product goes into solution, or in the presence of a non-solvent for the product. Examples of esterification processes are those of Specifications 6463/15, 14101/15, 100,009, 101,555, 207,562, 309,201, 312,095, 312,096, 312,098, and 326,515, [all in Class 2 (ii)].  The esters may be subjected to ripening processes as described, for example, in Specifications 20977/11, 20852/12, and 300,140, [all in Class 2 (ii)].  The cellulose may also be subjected to etherification, as is described, for example, in Specifications 164,374, 164,375, 164,377, and 277,721, [all in Class 2 (ii)].  The esters and ethers may be employed in the production of artificial silk, films, varnishes, plastic masses, moulding powders, and the like. In one example, wood chips are treated with 2 to 3 per cent caustic soda at a temperature of 140 to 150 DEG  C. until the lignins are substantially removed, after which sulphur dioxide is blown in and cooking is continued at 100 to 120 DEG  C. under a pressure of 4 to 6 atmospheres.  In another example, wood chips are treated with caustic soda as in the previous example then heated at 100 to 120 DEG C. with a liquor containing 1 per cent of free sulphur dioxide and 0.5 per cent of sulphur dioxide in the form of calcium bisulphite.
