Linear polyesteramides are prepared by heating at 200-350‹ C., in an inert atmosphere or vacuum a compound or compounds contains ing carboxylic acid, amino and hydroxyl groupas the sole reactive groups in the presence of 0À005 to 2% by wt. of the reaction mixture of an organo-tin compound. The carboxylic acid groups are present in the form of dicarboxylic acids, amino acids or hydroxy acids. The amino groups which are directly attached to an aromatic nucleus are present as diamines, amino alcohols or amino acids. The hydroxyl groups are present as diols, amino alcohols or hydroxy acids; the reactive OH group is separated from the other functional groups by at least two carbon atoms and is attached to an organic radical in which the carbon atom attached to OH is attached to adjacent atoms, at least one of which is hydrogen, by single valence bonds. A variety of combinations of the above compounds are described and claimed. When a dicarboxylic acid is used it may be an aliphatic acid having at least 4 carbon atoms between the carboxyl groups or an aromatic or alicyclic dicarboxylic acid having at least 3 carbon atoms between the carboxyl groups. A mixture of an alicyclic acid with either an aromatic or aliphatic acid may be used. A diamine may be used in which the amino groups are separated by at least 3 carbon atoms. Amino acids are suitable in which the carboxyl group is attached to an aromatic ring or is separated therefrom by an alkylene, cycloalkylene or alkyleneoxy group. Hydroxy acids of similar structure may also be employed. Amino alcohols may be used in which the amino group is attached to an aromatic ring and the OH group is separated therefrom by an alkylene, cycloalkyl. ene or alkyleneoxy group. In preferred embodiments the reactants are heated at 200- 300‹ C. for 30-90 minutes to give a prepolymer. The latter is further polymerized either by stirring the melt in vacuum for ¢-3 hours at 200-350‹ C. or by granulating the prepolymer to a particle size of 0À03 inch or smaller followed by heating in vacuum or inert atmosphere below its M.P. for at least one hour. Suitable organotin compounds are di- or tetra-valent, the valencies being satisfied by alkyl or aryl groups or electronegative radicals.

Abstract: 1426694 Paper-making SCOTT PAPER CO 2 April 1974 14643/74 Headings D2A and D2B [Also in Division G1] A method of making a soft absorbent creped paper web of uniform density comprises forming a web of principally lignocellulosic fibres by deposition of an aqueous slurry of the fibres on a foraminous surface, removing water from the web, the water being removed without subjecting the web to a pressure of more than 5 psi until it is at least 80% dry, whereby the fibres are bonded together substantially by papermaking bonds, and thereafter creping the web. As shown stock, which may include small amounts of non-lignocellulosic fibres such as cotton, wool or rayon, is deposited from a distribution means 10 onto a foudrinier wire 16 passing over a breast roll 17, table rolls 18, driven rolls 20 and guide rolls 21-23. The web is then transferred onto a drying fabric 24 at a pick up roll 25, transfer being assisted by a jet of steam or air from a header 26. The web is carried on fabric 24 through a drier 27, e.g. radiant heat lamps, a tunnel drier or a transpiration drier, and is subsequently transferred by a roll 31 to a creping drum 32, e.g. a Yankee drier. A creping adhesive may be applied, by a sprayer 37 or roller, to the web surface or the surface of the drum 32 particularly if the web is 90% or more dry. The adhesive may reduce the web dryness by 10-20%. The web is preferably dried by the drum 32 to 95% or more then creped by a blade 38 which also removes the web from the drum. Examples of the method are described using a pulp consisting of 80% kraft softwood and 20% kraft hardwood to form webs dried to 95% and 98% before being subjected to substantial compression. The resulting webs have a density under no load of less than 0.3 gm/cm<SP>3</SP> and a tensile energy absorption/stiffness ratio greater than 0.5 Î 10<SP>-4</SP> for a dry basis weight of between 10 and 30 1bs/2880 sq. ft.

[Class 74 (ii).] Openwork is produced by alternately holding and releasing sinker loops for a certain number of courses. The sinker loops are held by needles which take no other part in the knitting operations. By causing loop retention to occur at different wales in different courses the disposition of the openwork effect can be varied. The fabric may be knitted on the dial needles of a six-feeder circular machine, yarn being withheld from one of the feeders. While the dial needles are knitting the cylinder needles take and accumulate the sinker loops for five courses and cast off on the sixth. No clearing cam is provided for the cylinder cams but selected needles are raised by jacks as described in Specification 329,369, [Class 74 (ii), Knitting &c.], at each of the first five feeds. At the sixth feed station, all the cylinder needles are raised and since no yarn is fed at this station, the accumulated loops are cast off. Accumulation of loops can then be started again on the same or a different selection of needles, and so on. Figs. 1, 2, 3, and 4 (not shown) illustrate suitable cam systems.
