Title: Improvements relating to telephone systems
IPC: H04M1/654
Filed: 1957-08-26
Abstract: 910,951. Substation equipment. RUBENSTEIN, L. Nov. 26, 1958 [Aug. 26, 1957], No. 26852/57. Class 40 (4). A device for recording information transmitted in the form of a train of dial impulses by a calling subscriber comprises a type weel having a plurality of characters formed on an end face, a type head, a relay arranged to be energized by the train of impulses, first means operable by the relay for moving the type wheel in an axial direction, and second means operable by the relay for rotating the type wheel about its axis, whereby energization of the relay causes axial movement of the type wheel by the first means and rotation of the type wheel by the second means by an amount such that a character on the wheel corresponding to the information contained in the train of impulses is brought to an operative position relative to the type head, and de-energization of the relay causes axial movement of the type wheel in the return direction so that the wheel impinges against the type head and forms a reproduction of the relevant character on paper placed between the type wheel and the type head. As shown, closure of manual switch 77 enables incoming ringing current (and later dial impulses) to be picked up inductively by coil 81, energizing relay 60 which operates a solenoid 36 and a stepping relay 28. The latter closes switch 27 by means of cam 25. After a predetermined number of steps, cam 25 causes a lever 23 to lift the hand-set 21, stopping the ringing and releasing relay 60 and solenoid 36. Relay 28 steps slowly by self-interruption, producing an audible signal by rubbing ratchet wheel 29 or cam 25 against a vane or by some other method. If the calling subscriber then dials his own number or some other code message, solenoid 36 operates for each digit, advancing a type stop 42 and a paper strip 45 and causing a type wheel 31 to engage ratchet wheel 29 which is driven by stepping relay 28 at each impulse. At the end of each digit, solenoid 36 is released and a spring 33 drives type wheel 31 against the paper strip 45 backed by type stop 42 which is thereby unlatched from a spring 44. In a modification, Fig. 11 (not shown), the device is connected directly to the telephone circuit, dispensing with the inductive pick-up and the means for lifting the hand-set.

Patent GB-362523-A (GB)
Title: Improvements in or relating to threads or fabrics made of or containing cellulose esters
Filed: 1930-09-10
Abstract: Cr<\>zepe threads are formed of or contain filaments of an organic ester of cellulose which filaments are highly twisted together and are saponified at intervals along their length. In producing the threads, the saponification is effected while the threads have little or no twist or after they have received a twist of 20-30 turns per inch or more, the threads after saponification being twisted to 60, 70, 80 or more turns per inch. Suitable saponifying agents include sodium carbonate, potassium silicate, trisodium phosphate, potassium and sodium hydroxides, &c. The saponifying-agent may be applied in solution or as a paste, e.g. thickened with gum tragacanth, gum tragasol, dextrin, British gum etc.; with or without swelling agent, e.g. thiocyanates or ethyl or methyl alcohol. Buffer salts or modifying agents may also be added and the degree of saponification may be up to 3, 5, 10 or even 20 per cent less in weight. The saponifying material is suitably applied by the methods described in Specification 332,263, [Class 2 (ii), Cellulose &c.], by wicks, rollers, rods, &c. After treatment the threads are preferably passed through a bath of very dilute acid to neutralize residual saponifying-material and are then quickly dried at a fairly high temperature, e.g. 65-80 DEG  C.  The dried threads are collected on bobbins and transferred to a twisting-machine.  The saponification may be applied continuously with production, as in Specification 332,263 in which case no special drying treatment is necessary, or in the course of bobbin to bobbin &c. winding &c. operations.  The finished threads are woven into fabric which is subjected to the action of an aqueous or other scouring bath to produce the cr<\>zepe effect.  The scouring bath may include swelling-agents as described in Specifications 351,999 and 352,000 so that both the saponified and unsaponified portions of the thread are swollen.  In an example, filaments of cellulose acetate from a number of bobbins are led in parallel to a fluted roller supplied by a dip roller dipping into a trough of saponifying liquid or paste, e.g. an aqueous or alcoholic solution containing 1-5 or even up to 30 per cent of caustic soda. The threads are then run through a bath of very dilute hydrochloric or acetic acid and are then passed around drums heated to about 70 DEG  C. whereby the threads are dried and saponification is completed.  The dried threads are passed to bobbins which are subsequently taken to twisting devices to impart a high degree of twist.  Alternatively, threads may be taken from twisting-devices, e.g. as described in Specification 304,806, [Class 120 (ii), Spinning, twisting, &c.], and laid over a fluted roller, the twisting-device imparting a twist of say 20-30 turns per inch.  The saponified threads may be coated with sizes, e.g. as described in Specifications 348,589, 352,451, 356,233, 357,084 and 357,169.
