Patent GB-837797-A (GB)
Title: Process for the homogenisation of pores
IPC: B01D59/14
Filed: 1958-04-03
Abstract: Porous material is heated to the decomposition temperature of a volatile compound which precipitates solids on decomposition and then intermittently treated with small amounts of the compound. Solids are thus preferentially deposited in the larger pores, the result being a material of uniform pore size.  The example discloses the deposition of nickel from a nickel carbonyl/inert gas mixture under vacuum conditions in a nickel diaphragm which is subsequently treated with fluorine or hydrofluoric acid, preferably in admixture with an inert gas or steam, before being used in the separation of uranium isotopes by way of uranium hexafluoride.  Reference is also made to the deposition of silica from a silicon tetrafluoride/steam mixture, and to the treatment of glass frits and sintered ceramic materials. Specification 832,317 is referred to.ALSO:Porous material is heated to the decomposition temperature of a volatile compound which precipitates solids on decomposition and then intermittently treated with small amounts of the compound.

Title: Improvements relating to the manufacture of synthetic resinous compositions
IPC: C08L61/06
Filed: 1947-04-23
Abstract: Thermosetting resins are obtained by heating a liquid "resol" (prepared by refluxing a phenol with an equimolar or greater amount of formaldehyde in alkaline medium) and a liquid or solid "novolak" (prepared by heating a phenol with less than an equimolar amount of formaldehyde in acid medium) in proportions such that the molar ratio of initial phenol to initial formaldehyde is 0.85-1.20 to 1 in the presence of excess of alkali until substantially all uncombined phenol is eliminated, e.g. up to 120 DEG  C. under vacuum. Preferably, the resol is present in such proportion that its catalyst alkali is stoichiometrically in excess of the acid catalyst of the novolak, but alkali may be added if necessary.  The products may be ground and mixed with wood flour, lime and stearic acid to form moulding powders. Examples illustrate the heating together of resols prepared from phenol and formalin in the presence of caustic soda and novolaks prepared from phenol and formalin in the presence of sulphuric or oxalic acid.  Specification 404,060 is referred to.

The pad 1 is of vulcanized fibre, a phenol condensation product or other material, preferably heat insulating, in which is secured a pin 2 having a lefthand thread, and a pin 4 forming a pivot for a clip 5. The clip has a tongue 6 adapted to engage in one of a number of depressions 7 in the pad 1. The curler rod 8 screws.on to the pin 2 and is formed with a helical rib or groove 9 of constant or gradually diminishing pitch engaging with a thread or a projection such as a ball on the collar 10. A sleeve 12 forming a handle rotates on ball bearings on the collar 10 and on ball bearings 13 on an internal sleeve 26 integral with the collar and secured by lock nuts 25. A ratchet clutch 16 between the handle 12 and the collar 10 is disengageable against the action of a spring by a pin 15 moving in a slot 14 in the handle. In a modification, the handle 12 rotates freely on the sleeve 26. The collar 10 has a bracket 17 supporting a pair of pins 18 serving as guide for a convex cap 19 normally pressed outwardly by compression springs, and the cap cooperates with a roller 21 on a bar hinging about one of the pins 18 and slotted to engage around the other pin. A strand of hair enclosed in a thin cylindrical or conical tube of paper, knitted or woven fabric is passed into the opening 24 in the pad and secured by the clip 5. The rod 8 is then threaded on the pin 2, the strand of hair passed over the plate 19 and the pivoted bar supporting the roller 21 brought into the position shown to form a clamp through which the hair can slide with frictional resistance. By withdrawing the handle 12 axially, the collar 10 is withdrawn and also stated to wind the hair on the rod 8. If the resistance to movement is too great, a turn or two of the collar 10 may be effected by locking the ratchet 16 and turning the handle, or in the modified construction referred to above, by turning the knurled nuts 25. After the heating operation, the rod 8 is withdrawn by unscrewing. Rods of differing lengths may be used.
