Patent GB-580498-A (GB)
Title: Improvements in the manufacture of artificial filaments
IPC: D01F2/28
Filed: 1944-03-29
Abstract: Artificial filaments having a basis of an organic derivative of cellulose are stretched by at least 100 per cent of their original length with the aid of a softening agent comprising an active substance in a concentration between that which dissolves the materials or destroys their structure and about 2 per cent by volume below such concentration, the softening agent being employed under such conditions as to give slip stretch as defined below. Alternatively, the filaments are stretched by at least 100 per cent of their original length with the aid of a softening agent containing an active substance in such concentration that the stretching tension required is between 0.1 and 0.5 grams per 100 denier, under such conditions that slip stretch is obtained. Slip stretch denotes stretch by which the extension of the yarn is not reduced by more than 25 per cent on stretching the yarn by at least 100 per cent of its original length.  Suitable softening agents for filaments made from cellulose acetate are a mixture of acetone and benzene containing 37 to 41 per cent of acetone at 20-25 DEG  C., a 90/10 ethyl acetate-toluene mixture at 30 DEG  C., and a 95/5 ethyl acetate-carbon tetrachloride mixture at 30 DEG  C.  In general, the materials are preferably treated with a mixture of a hydrophile organic softening liquid and an inert hydrophobe organic liquid.  The materials may be pretreated with a softening agent containing a slightly lower concentration of softening liquid or with a softening agent used at a slightly lower temperature.  In example (1), yarn made of acetone-soluble cellulose acetate of 54 per cent acetyl value and having an extensibility of about 25 per cent is immersed in a mixture of 90 per cent ethyl acetate and 10 per cent toluene at 30 DEG  C. for 30 seconds.  It is then stretched 100 per cent of its original length, rinsed with toluene and allowed to dry without tension. In example (2), the softening agent consists of 95 per cent ethyl acetate and 5 per cent carbon tetrachloride at 30 DEG  C.  In example (3), a similar yarn is stretched while passing through a mixture of 41 per cent acetone and 59 per cent benzene at 20 DEG  C., and the rate of travel is adjusted so that the stretching tension is about 0.3 grams per 100 denier.  Specifications 421,614 and 570,588 are referred to.

Title: A composite board and its method of manufacture
Inventor: POLOVTSEFF BORIS
IPC: D21J1/00
Filed: 1948-02-27
Abstract: A composite board consists of a layer of low density, loosely consolidated, comminuted material in the form of a dry preformed board and an outer layer of highly consolidated material of greater strength and density applied to one or both surfaces of the preformed board, such outer layer being formed of a loose mixture of comminuted wood and adhesive being simultaneously consolidated and caused to adhere by heat and pressure.  In one form the hardened board is made from 15 per cent (by weight) waste paper and 85 per cent comminuted wood, the paper first being pulped with water and the pulp then mixed with the wood, the resultant mixture being pressed to remove surplus moisture and dried in a suitable mould.  The mixture for the outer layers is then made up, e.g. 360 pounds of comminuted wood, 67 pounds of urea-formaldehyde resin, 6 3/4 pounds of chemical accelerator and 22 1/2 pounds of water, and a layer of the mixture is placed on the surface of a caul.  The hardened central board is then placed on the layer, a further layer of mixture placed on the board and another caul placed on the latter.  The whole is then stacked between the platens of a press and subjected to a pressure of approximately 200 pounds per square inch at 100-140 DEG  C. for about 24 minutes.  The heat is then shut off and when the board has cooled sufficiently the pressure is released and the board removed.  The central board may be made more porous by adding a stabilized colloid in the form of a foam to the mixture. Specification 595,474 is referred to.

Title: Process for the preparation of organopolysiloxanes
Inventor: BARONNIER JEAN HENRI
IPC: C08G77/00
Filed: 1967-02-09
Abstract: The reaction product of an alkali metal with an aminophosphine oxide is used as an equilibration catalyst in polymerizing organopolysiloxanes with or without organosilanes. The siloxanes may contain saturated or unsaturated hydrocarbon (h.c.) radicals, with or without halo-, amino- or cyanato-substituents hydroxyl or hydrocarbonoxy radicals.  The amino-phosphines used may have the formula <FORM:1105844/C3/1> in which R1 and R2 are each a monovalent h.c. radical or are joined to form with the N a heterocyclic radical. The catalyst can be made by allowing the alkali metal to dissolve in the anhydrous amino-phosphine oxide, or a mixture of the oxide and a liquid organopolysiloxane, in a nitrogen atmosphere and with or without heating.  The polymerization can be effected at 20 DEG  to 200 DEG  C.  In a typical Example (1) a catalyst solution, obtained by dissolving K in anhydrous hexamethylphosphorotriamide and octamethylcyclotetrasiloxane and diluting the mixture with toluene, was added to octamethylcyclotetrasiloxane maintained at 100 DEG  C. in a nitrogen atmosphere, and after 1 hour the contents were cooled and the catalyst neutralized, by adding ethyliodide and removing volatiles by heating under reduced pressure, to yield a siloxane gum.
