Inventor: REED WILLIAM SUMNER
Filed: 1908-11-11
Granted: 1909-03-25
Abstract: 24,215. Reed, W. S. Nov. 11. Couplings, disconnectible; screw couplings.- The female member of a coupling for hose and like pipes has jaws 8 with serrations adapted to engage the screw-thread 4 of the male member. The jaws are housed in recesses and are pivoted at 9 so that the member 4 can be pushed into place. The jaws are pressed inwards by springs 12 housed in a groove 14. Any tendency to pull the coupling apart causes the jaws to grip the member 4 more tightly. The pivots 9 may be relieved of longitudinal thrust by a flanged screw-cap 16, which also limits the inward, but not the outward, movement of the jaws. A slight rotation of the male member, when the parts are assembled, compresses a packing- ring 21. The parts are uncoupled by unscrewing. The device may be applied to ordinary screw couplings by a screw-thread 20.

Title: Method of and Apparatus for the Extraction of Grease and similar Matter from and for Treating Wool, Skins, Textile and other Materials.
Inventor: MAYO CHARLES ROBERT
IPC: C11B11/00
Filed: 1909-04-10
Granted: 1910-06-10
Abstract: 8600. Mayo, C. R. April 10. [Cognate Applications, 17,125/09 and 22,615/09.] Fats and fatty oils, extracting by solvents. A plant for degreasing wool, skins, textiles, &c. comprises one or more extractors, a still, and a condensing-apparatus, all maintained under reduced pressure. The arrangement is of the type in which the used solvent in the extractors is displaced by fresh solvent, and is thus caused to overflow from the upper end into the still. The condenser comprises a vessel containing a column of water, through or into which the condensed solvent, for example, carbon bisulphide, is discharged, the air-pump suction communicating with the space above the water. The airpump discharges into a scrubber, preferably through the intermediary of a compression chamber, in which the pressure is regulated by an exit valve. The extractors a, b, c are exhausted at the beginning of the operation by means of pipes 27, 26, leading to the air-pump 7, the extractors being meanwhile heated by admitting steam to the jackets e, in order to ensure the removal of any moisture the material may contain. The valves are then manipulated so as to exhaust the whole of the apparatus by the main suction pipe 8, the open system then comprising the water-container 3, previously referred to, an evaporative condenser y, a still o, and extractors a, b, c, together with the communicating pipes 4, 5, and 45, 43. Solvent is then forced through a pipe 21 from the reservoir 6 by the head of water in the container 3, and passes in succession through the extractors by way of pipes 15, 17, 24, one charge in each cycle being made to overflow into the still o. To empty any extractor, steam is admitted to the jacket to cause evaporation of the solvent and thus generate pressure, which, on opening suitable valves, forces the solvent either back into the reservoir 6, or forward to the next extractor. The vapour in the extractor is now drawn off by the pipes 43, 45, and finally air, steam, or both, are admitted by a cock 31, and the residual solvent vapour is led to the pump by the pipes 27, 26. The upper layers of grease-laden solvent alone may be run from the extractor c to the still at any stage of the operation. The still may be provided with internal film-forming baffles. The air in the compression chamber, into which the air-pump discharges, is allowed to stand and cool, and then is further cooled by opening the exit cock and allowing the air to expand suddenly into the scrubber 12. The scrubber is filled with water, and may be provided with baffles so that the ascending air bubbles may follow a tortuous course.

Title: Improvements in the Transmission of Speech and Audible Signals through Water by Means of Sound Vibrations.
Inventor: ROSENTHAL HANS
IPC: G01S1/72
Filed: 1910-07-01
Granted: 1911-02-09
Abstract: 15,837. Rosenthal, H. July 8, 1909, [Convention date]. Subaqueous sound signals.-A sound-producer for the transmission of speech and audible signals through water consists of a mass of metal M which is caused to vibrate by means of an alternating or pulsating current. The windings conducting the current may themselves act as the sound-emitter, or the whole or part of the ship's shell may be used. The mass of metal may take the form of a hollow metal cylinder open at one end, and may be permanently magnetized by an auxiliary winding E. The vibrating body may be tuned to the frequency of the current employed, and a directive effect may be produced by using two transmitters arranged at a distance apart equal to half the wave-length of the sound used. In the transmission of speech, a microphone Mi is arranged in circuit with the alternating generator. Reference has been directed by the Comptroller to Specification 3359/07.

Abstract: 26,390. Taylor, A. M. Nov. 14. [Addition to 20,867/09.] No Patent granted (Sealing fee not paid). Commutator switching-arrangements; phase, changing; transformers.-In a system for converting direct currents into alternating currents, and vice versa, of the kind described in the parent Specification, wherein means are provided for altering the wave form of the alternating current, the transformer P is provided with an exciting-coil E supplied from a small synchronous alternator N driven from the motor M, which drives the commutators A, B, for the purpose of magnetically saturating the core and the transformer at certain periods. A small auxiliary transformer Z is also employed having an unsaturated core, its primary coil C being in series with the exciting winding of the main transformer, and its secondary coil L being in series with the secondary winding S of the main transformer. This effects the requisite deformations of the wave of electromotive force applied to the exciting-coil E, and at the same time adds a component to the alternating electromotive force delivered by the secondary winding S of the main transformer, so that a sine wave of electromotive force is transmitted to the mains D. The exciting-coil E may be connected to the mains D by means of a switch O, when the system is being used for rectifying alternating currents. The secondary coil S of the transformer P has two tappings, and a switch Q enables a part thereof to be cut out to compensate for the pressure drop in the transformer when reversed. The exciting-coil E may also have an additional number of turns adapted to be thrown into circuit by a switch R, the transformer P being then worked in an unsaturated condition with improved efficiency. In this case, the alternator N is designed to give the special wave shape which the primary winding of the transformer has to deliver for commutation purposes. The auxiliary transformer Z in this case is fed with a special wave from an auxiliary winding on the alternator N so as to deliver a compensating wave of electromotive force in the circuit of the coil S. The Figure shows the connexions for one phase only, the general arrangement for three-phase circuits being as set forth in the parent Specification.

[Addition to 13,406/10.] Controllers, actuating and retarding mechanism for; controllers with auxiliary switches. - In a solenoid motor-starter of the type described in the parent Specification, the travel of the speedregulating arm 3, Fig. 1, is adjusted by varying the angle between it and the solenoid-operated arm 11 to which it is attached. This is effected by causing a pin 14, Fig. 2, which is depressed by a spring 17 in a housing 15 on the arm 11, to enter one of a series of holes 19 in an extension of the arm 3. The armature resistance 44 is first cut out, and after that the desired amount of field resistance 46 is inserted. A screw-pin 26 on the arm 11 opens a switch 27 at the limit of travel, and inserts a resistance 52 into the solenoid circuit. The end of the dash-pot has two series of holes 36, 37 connected by a by-pass passage, thus relieving the retardation at the end of the travel. The removal of retardation, added to the increased pull on the magnetic core as it enters the solenoid, causes a rapid break at the switch 27.
