Title: Improvements in or relating to the treatment of materials consisting wholly or partly of wool
Inventor: ALEXANDER PETER
IPC: D06M13/196
Filed: 1949-01-12
Abstract: Perpropionic and per-n-butyric acids are prepared in a similar manner to peracetic acid (see Ind. and Eng. Chem., 1947, 39, 847) by condensing equimolecular proportions of hydrogen peroxide and propionic or n-butyric acid in the presence of suphuric acid.  The reaction mixture initially contains the reactants in the proportions of 1.5 gm. mols. of the initial acid to 1 gm. mol. of the peroxide and is allowed to stand for 24 hours at 0 DEG  C.  The per-acids may be used for treating wool (see Group IV (c)).ALSO:Materials consisting wholly or partly of wool are treated, to reduce their tendency to felt and shrink, with a solution of a compound of the formula <FORM:0656938/IV (c)/1> wherein R is hydrogen or an alkyl, aryl, substituted alkyl or substituted aryl group and M is hydrogen or a metal, in a solvent which does not decompose the compound.  R may be an alkyl group containing not more than five carbon atoms and the compound may be used in aqueous solution, in which case an alkali (other than a nitrogen base such as ammonia) may be added to render the solution neutral or alkaline to a pH of less than 11. Alternatively, the solvent may be an organic solvent such as chloroform or carbon tetrachloride.  In an example, all-wool knitted fabric is treated at room temperature with a solution of 45 per cent by weight of peracetic acid in acetic acid diluted with 10 times its weight of water, and thereafter rinsed with water.  Examples are given also of the treatment of wool fabrics with perpropionic acid, per-n-butyric acid (see Group IV (b)), and perbenzoic acid in carbon tetrachloride or chloroform.  Data are furnished of the shrinkage of the fabric (produced by milling in soap solution) before and after treatment as above and before and after treatment under similar conditions with hydrogen peroxide and tertiary butyl hydroperoxide, ditertiary butyl peroxide, tertiary butyl perbenzoate, benzoyl peroxide and acetyl benzoyl peroxide respectively.

Title: Relay congestion detecting method in store and forward switching network
Inventor: ASAMURA MITSURU
IPC: H04L47/265
Filed: 1995-01-05
Abstract: PURPOSE: To reduce burden on the processing of congestion detection notice of a tandem switch by judging congestion by measuring the reception line working ratio of or reception data quantity on a relay line by an incoming call side exchange. CONSTITUTION: When communication is performed via the tandem switches 21, 22 by setting a logic channel between exchanges 20 and 23, the exchange 23 measures the reception line working ratio or data quantity from the tandem switch 22 by, for example, a reception buffer working ratio. When the line working ratio or data quantity exceeds a threshold value in fixed time, it is judged that the congestion occurs in the relay line 42 of the tandem switch 22, and it is informed to the exchange 20. In this way, congestion control processing such as the congestion detection notice, etc., on a tandem switch 22 side is reduced, and the congestion of the tandem switch is prevented from being further propagated by the congestion processing when the congestion occurs.
