Title: Improvement in Telephone Exchange Systems.
Filed: 1911-07-11
Granted: 1912-01-11
Abstract: 16,075. Western Electric Co., [Western Electric Co.]. July 11. Automatic exchange systems; exchange systems.-At an exchange at which a reverting call may be received over a party-line, it is arranged that, instead of the test lead of the called subscriber showing busy on account of the connexion of the calling subscriber, a special circuit is completed to indicate to the exchange operator that it is a reverting call. In order that this indication may not be given in the case of lines on which reverting calls are not possible, a reversed arrangement of batteries is used to prevent actuation of the polarized relay that controls the signal. In the Figure, the connexions are shown at a time when a reverting call has been received on the party-line 22 and the automatic switch 32 has been moved by the operator to the contacts 16, 17, 18 of the called subscriber. The battery 9 would in this case not energize the test relay 49 on account of the connexion to ground through plug sleeve 3, lead 25, and winding 28. At the moment that the connexion is made, however, it is arranged that the switch 36 is moved either manually or automatically to connect the lead 25 momentarily with the lead 38. The line 21 now tests idle, and the current from the battery 9 energizes the polarized relay 40, which by closing the contact 41, completes a circuit for the battery 42 over the relay 45, leads 38, 25, 6 and 21, to the test relay 49. This current is sufficient to energize the relay 45, which is not initially energized by currents over the high-resistance windings 40, 31. The relay 45 brings into circuit the reverting-call indicator 52, and is retained energized by the connexion over the winding 40 until the switch 46 is opened. In order that the indicator 52 may not be operated during a connexion with a line 53 such as a private branch exchange line on which reverting calls are not possible, the battery 15 is arranged to be of opposite polarity to the battery 9, so that the polarized relay 40 is not operated by it.

Title: Improvements in the Manufacture of Urea.
Inventor: IMMENDORFF HEINRICH
IPC: C07C273/06
Filed: 1911-07-25
Granted: 1912-02-22
Abstract: 17,018. Immendorff, H., and Kappen, H. July 25. Urea.-Urea is produced by treating cyanamide solutions, freed from the base or not, with catalysts in an acid solution, or in a neutral solution preferably maintained permanently neutral by the addition of acid during the reaction. The solution is preferably strongly agitated, or the catalyst is otherwise uniformly distributed; or the cyanamide solution may drip over the catalyst contained in suitable apparatus. The reaction can also be accelerated by bringing the reaction mixture as quickly as possible to the desired temperature, for example by previously heating the cyanamide solution. Suitable catalysts are manganese peroxide, ferric oxide and hydroxide, preferably calcined, chromium oxide and hydroxide, stannic oxide, and lead monoxide and peroxide. Pure urea is obtained from the reaction mass by precipitation of the calcium with suitable salts, and the catalyst may be regenerated, when necessary, by treatment with acid, water, &c. In order to obtain strong solutions of urea, the initiallyobtained weak solution is used as a solvent for a further quantity of cyanamide, which is then converted into urea, and so on. As an alternative a weak calcium cyanamide solution obtained by direct solution is freed from calcium by means of a suitable acid, and the solution of free cyanamide used as a solvent for a further quantity of calcium cyanamide, from which calcium is again precipitated. By repetition, a solution of high concentration and suitable for conversion into urea is obtained.

Granted: 1912-10-24
Abstract: 24,011. Abbott, E. J. Oct. 30. [Addition to 15,076/09.] Damping - machines. -Relates to the general construction of the machine described in the parent Specification a n d in Specification 24,655/10, and i n - cludes special means for damping envelope flaps and the end stamps of the stamp strip. The envelope feeding and damping slide 11, Fig. 6, is reciprocated by an adjustable connexion from a crank on the driving - shaft, and the connecting - rod is adapted to strike an adjustable stop on a lever, of which one end bears beneath the water well 31 and raises this to bring its absorbent pad 34 into contact with the slide 11. The well 31 is detachably and pivotally mounted on pins 33. Arms 41 pivoted at 42 carry the roller 3, upon which the free eud of the pivoted envelope magazine 2 rests, and these are rocked so that the roller presses the flap of an envelope on to the wet part of the slide 11 as it is being fed from the magazine, and so that the roller is lowered out of contact with the slide during the return movement. The slide raises the roller by depressing the free ends of the arms 41, and a step 44' on a spring-actuated lever 44 pivoted at 45 holds the arms 41 and the roller 3 in the raised position. When an envelope is fed forward, the slide 11 rocks the lever 44, and the roller 3 drops until the arms 41 are supported by a step 44<11> on the lever. When a stamp is projected beneath the affixing- plunger 120, Fig. 6, it is moistened 'by a wick 131 in a well 130 carried by a lever 129 pivoted at 128<1> to a slide 128. The lever 129 is caused to slide by the envelope-feeding plate 11 contacting, when moving in one direction, with a depending member 137 of the slide 128, and when moving in the opposite direction, with a depending portion of the end of the lever, but before the latter contact is made, the slide 11 engages a roller at the end of the lever to rock the wick 131 into engagement with the stamp, which is supported above by a plate 139 carried by the slide 128 and acted upon by a spring 140.

Title: Improvements in the Manufacture of Artificial Silk from Viscose.
Inventor: ELLIS GEORGE BELOE
IPC: D01F2/06
Filed: 1912-10-02
Granted: 1913-06-19
Abstract: 22,436. Ellis, G. B., [Chemische Fabrik von Heyden Akt.-Ges.]. Oct. 2. Viscose.-Artificial threads are produced by squirting viscose solutions into aqueous solutions of mineral acids or acid salts thereof, with or without the addition of neutral salts, and under such conditions that the threads on leaving the bath still consist of viscose. The water-soluble threads then pass to a second bath of diluted acid, or salt solutions with or without acid, and are there rendered insoluble. They may also be rendered insoluble without the use of a second bath by spinning under such conditions that sufficient acid or acid salt is carried over from the spinning-bath to enable the viscose to be decomposed when wound on the spools. The concentration of the spinning-bath, its temperature, the length and speed of travel therein, and the length and speed of travel between the first bath and the second bath or other spool, are important conditions in the process. Specifications 2529/02, 17,503/02, and 16,720/11 are referred to.

Title: Improvements in and relating to Photographic Printing Paper and Transfer Processes.
Inventor: KENT FRANK WILLIAM
IPC: G03C1/805
Filed: 1912-12-23
Granted: 1913-12-23
Abstract: 29,616. Kent, F. W. Dec. 23. Plates, films, and papers; printing - paper; composite photographs; kinematograph picture films.-Relates to the treatment of photographic images by production on a sensitized basis of paper or the like previously fully saturated with wax followed by transfer to a somewhat adhesive stratum of resinoid or like or equivalent substance. The waxed basis may be polished or burnished by friction. Two sheets of waxed paper may be used back to back and coated on both sides to prevent curling. Vogel's sensitive emulsion, as described in Specification 2162/80, may be used. For other sensitive media the insensitive basis of Vogel's emulsion may be used as a substratum, or other substrata containing pyroxylin, gelatin, and acetic acid. The receiving support for the image is treated with a resinous or resinoid cement or a solution of india-rubber in benzol, or both the receiving surface and the image may be coated. The separation of the temporary wax support may be facilitated by heat or a solvent which softens the wax, such as benzol. A harder resinous or resinoid body such as damar may be used on one surface and may be mixed with the rubber cement. The finished print may be protected with coating of viscose, albumen, boracic lac varnish, india-rubber, or celluloid. In order to superimpose accurately successive prints, and more especially colour prints, pins may be used in the camera, and the negative supports perforated to engage these pins. The transfer supports and the final receiving support may also be punched to correspond with the camera registration pins. Alternatively and where it is not convenient to perforate the receiving support, the perforations may be used as a visible registration for successive transfers after the first. In the case of glass negatives, each negative may be margined with perforatable material. In the case of kinematograph films, registration is effected by the sprocket holes.
