Title: Improvements in or relating to the manufacture of textiles
IPC: D01C3/00
Filed: 1934-11-02
Abstract: 446,533. Obtaining tanned fibres. FREUDENBERG GES., C., Weinheim, Baden, Germany. Nov. 2, 1934, Nos. 31565, 31566, and 31567. Convention dates, Nov. 2, 1933, May 25, 1934, and July 23, 1934. [Class 76] [See also Group IX] Fibres suitable for textile purposes are obtained from animal skins by treating the swollen and coarsely shredded skins with dehydrating organic liquids miscible with water such as alcohol, acetone, and the like and/or with tanning-agents and finely shredding the material so treated. The bulk of the water in the coarse swollen material may be removed by mechanical means before the treatment with organic liquids &c., and it may first be treated with water, alkalies, alkaline earths or acids for the removal of substances which cause the fibres to gum up or become horny. The treatment with chemical agents may be in stages between which the material is finely shredded. The shredding and other treatments may be carried out while the material is transported by a conveyer device and the shredding is effected in such a manner as to dispose the fibres in parallel arrangement. Usual mineral, vegetable or synthetic tanning agents may be used to treat the fibres and also pseudo tanning agents such as oils, fats, blubber. The finished fibres may be treated with softening agents such as degras, egg oil and olein. The finished fibres may be worked up with other fibres, e.g. wool, by usual textile methods and if the fibrous material has not been tanned the worked up products may be treated in the hank or piece with tanning-agents. Specification 439,532 is referred to.

Title: Improvements in and relating to transmission of signals in printing telegraphy employing for transmission voice frequency or high frequency alternating currents
IPC: H04L27/02
Filed: 1927-11-26
Abstract: 307,318. Evans, G. T. Nov. 26, 1927. Type-printing telegraphs.-Relates to typeprinting telegraph transmitters of the kind by which currents of voice or higher frequency are transmitted, and consists in means for intermittently short-circuiting an a.c. supply which is continuously applied to the line, the need for contact-making relays being thus eliminated. The transmitter can be tested by causing it to operate a local receiver. Thus an a.c. generator 1 is connected to the outgoing line 6, 7 through an impedance 8 and link circuit 2, 3, 4, and a shortcircuit is intermittently removed, so as to permit the production of signals by a start-stop cam acting in conjunction with a tape or key board transmitter. In order to test the operation of the transmitter a local receiver with line magnet 22 is connected to it through a link circuit 15, 16, and washers 19, 21. The high input impedance of the valves prevents reaction of the receiver on the transmitter. The receiver may be connected to line at 23 and used for the reception of line messages.
