Patent GB-191026948-A (GB)
Title: Improvements in or relating to Apparatus for Delivering Liquids, such as Liquid Soap, in Measured Quantities.
Inventor: REICHHARDT FRANZ
IPC: A47K5/12
Filed: 1910-11-19
Granted: 1911-08-03
Abstract: 26,948. Reichhardt, F. Nov. 20, 1909, [Convention date]. Hand-pumps; drip, preventing.-In order to prevent drip from the outlet in an apparatus for delivering measured quantities of liquid soap &c., the valves' between the measuring- chamber and the reservoir and outlet are so arranged that, when they return to their normal position, a suction is produced in the outlet, so that any liquid remaining is withdrawn into the measuring-chamber. In the form shown in Fig. 1, communication between the measuring- chamber 2 and the reservoir 1 and outlet 3 is controlled by valves 4, 8, the co-axial stems of which are normally forced upwards by springs 6, 10. On depressing a hollow-ball 7, the valves are lowered successively, and on release the expansion of the ball diminishes the pressure in the valve stem 5 and chamber 2 so as to cause withdrawal of the liquid in the outlet before the valve 8 closes. In a second construction, shown in Fig. 4, the valve 4 is constituted by a sleeve piston surrounding the hollow stem 5 cf the valve 8. The liquid flows to the measuring- chamber 2 through the stem, and the holes 21 which are closed when the piston descends. A similar arrangement, but with a solid stem 5, is also described. The Specification as open to inspection under Section 91 (3) (a) describes also two other piston forms of the invention, in one of which the piston is arranged to slide horizontally. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in Apparatus for Supplying Oxygen for Respiration in Mines and other places.
Inventor: HARGER JOHN
IPC: A62B7/08
Filed: 1911-02-18
Granted: 1911-08-10
Abstract: 4177. Harger, J. Feb. 18. Respirators. - In a portable breathing-apparatus for use in mines, the oxygen bag is charged with gas prepared as required by the ignition of oxygeniferous sticks, such as are described in Specification 17,628/10, [Class 90, Non - metallic elements]. The absorption box contains specially-prepared caustic, and, when used for long spells of work, calcium chloride and potassium permanganate or other oxidizing-agent to absorb ammonia and organic impurities respectively. The nitrogen in the air circuit is prevented from entering the oxygen bag. Each oxygeniferous stick is ignited in a metal tube A, and the gas passed through caustic G, cotton-wool V, and a tube B to a light rubber, mackintosh, oilcloth, or like storage bag E carried on the back. When the tap C is closed, the miner may exhale through the mouthpiece K, flexible pipe L, and light flap valve P into the thin metal absorption box I I carried on the shoulders, and the air returns through the pipe M and flap valve Q, oxygen being sucked in through the pipe J. The pipe N opens to the bag I at a point M such that there is about two litres space between it and the pipe J, so that as the miner exhales, no gas in the box I, other than pure oxygen, is forced back into the pipe J and bag E. The absorption box I is roughened on the outside and coated with lamp-black or white lead to assist cooling; it is loosely packed with finely-divided caustic obtained by squirting a hot strong solution throngh a small hole, or by allowing such a solution to cool in contact with plain or carbonized wood-wool, asbestos, wire network, or the like. A cotton-wool filter is usually placed at the point M to trap potassium chloride smoke. In a modified apparatus for medical use, the ignition tube A may be surrounded by the absorption chamber and cotton-wool filter, and the device may be hung on the wall, a bedstead, &c.

Title: Improvements in Yarn Preparing Machines.
IPC: D06C29/00
Filed: 1911-04-13
Granted: 1911-08-24
Abstract: 9196. Lees & Co., A., and Taylor, R. April 13. Yarns, calendering.-Relates to a retarding motion for ensuring the gradual application of the weight to the bottom roller of a yarnpreparing machine. The shaft 23 which carries the worm 25 for actuating the sector 30 that releases the intermediate roller 3 when the hank has been sufficiently long in the machine, is mounted on a counterweighted pivoted bracket 26 which swings outward, when the roller 3 automatically moves outward, and disengages a bevel-wheel 24 mounted on the shaft from a spaced wheel 29. The wheel 20 is combined with a bevel-wheel 33 gearing with a wheel 34 on a shaft 35 carrying a cam 36 and a pulley 37 weighted by a chain and weight 39. The cam engages a bowl 40 on a rod 41 sliding in guides and connected at its lower end to the pedal lever 19. When the pedal lever is depressed, on removal of the hank, and the pressure roller lowered, the weight 39 pulls round the cam 36 until a projection 360 thereon comes in contact with the bowl 40, which then retains the pressure roller in its lowered position until the attendant pushes back the intermediate roller with a fresh supply of yarn, thereby returning the swing-bracket to its original position and putting the pinion 24 in gear with the wheel 29 and the worm 25 in gear with the sector 30. The wheel 29 now drives the cam 36, which lowers the rod 41 operating the pedal lever and allows the weight gradually to raise the pressure roller 4 into contact with the roller 3; when this takes place, the space in the wheel 29 will have come opposite the teeth of the wheel 24, and further motion is stopped.

Title: Improvements in the Process and Apparatus for Electrolytically Measuring Electricity.
IPC: G01R22/02
Filed: 1911-05-04
Granted: 1911-06-08
Abstract: 10,792. Schott & Gen. May 23, 1910, [Convention date]. Electrolytic meters.-The change of valume of a liquid electrode is determined by tilting the vessel so as to transfer the liquid to a measuring-tube. In the meter shown, the cathode liquid overflows from a cup f<1> into a chamber f which communicates through a tube g with a graduated tube h. To determine the cathode gain the vessel is rotated in the clockwise direction till the tube h is vertical. The rotation is afterwards continued, the liquid filling the pocket i<o> and the excess returning to the chamber f. The rotation is then reversed until the liquid in the chamber f passes into the anode chamber, and finally, on restoring the vessel to its erect position, the liquid in the pocket i<o> flows into the cup f<1>. In a modification, in which the loss of the anode liquid is measured, the anode chamber communicates with an upwardly inclined measuring-tube, and the cathode chamber is extended in a parallel direction, so that, on tilting the vessel in one direction, the anode liquid only runs into the measuring-tube, and on tilting the vessel in the opposite direction, the cathode liquid is returned to the anode chamber.

Abstract: 2067. Robinson, A. S. F. Jan. 25. Transmission gear of invariable ratio.-In worm speed-reducing gearing applicable to motor-vehicles &c., two worms on intergeared shafts gear with opposite sides of a worm-wheel, the worm shafts being movable endways and connected to one another by pivotally mounted levers in order to divide the thrust and equally distribute the work. In the arrangement shown in Fig. 1, the worm-wheel a is driven simultaneously on opposite sides by worms b of similar thread mounted on shafts geared together by pinions c so as to rotate in opposite directions, the driving-shaft x being coupled to one of the pinions c by pins x'. The worm shafts are movable endways within ball bearings k and carry between collars i loose rings or sleeves h trunnioned in levers d, which are pivotally supported at e in the gear-box and pinned or geared to one another at f, a certain slackness in the joints allowing the required movements. The thrusts of the shafts being in opposite directions, one is balanced against the other by the arrangement of the levers d. Modified means of driving, and interconnecting the worm shafts b are described. The driving- shaft x may be arranged between the two worm shafts, being geared to one shaft by spur pinions and to the other by chain gearing. To reduce the size of the gears, the worm shaft may be connected by universal shafting to two other shafts arranged at a suitable distance apart, or the worm shafts may be inclined to one another in the plane of the worm-wheel and geared together by bevel-pinions. The fixed bearing-supports k may be dispensed with, the worm shafts being supported by a duplicated series of equalizing-levers such as d, arranged at one or both ends of the worm shafts. In another arrangement, worms of oppositely-inclined threads, rotating in the same direction, gear with a double worm-wheel in which the adjacent members have oppositely-inclined teeth. In this modification, the worm shafts may be connected by chain or spur gearing. Instead of oppositely-cut teeth on adjacent members, the right and left hand teeth of the wormwheel may be cut through one another on a single member. In the arrangement shown in Fig. 11 and designed to give maximum space between the road and the gear-box of a motorvehicle, the worm shafts b carry worm-wheels c and are driven by an horizontal worm shaft x.

Abstract: 16,883. Gray, W. E., Best, J. W. W., and Pyke, H. R. July 19. Counters actuated by electric means; zeroizing-mechanism.-Apparatus for indicating the number of revolutions of a shaft, for example during a pre-determined period of time, comprises an electro-magnet adapted to be rotated by the shaft and to be energized for the period by a clock-rotated contact device so as to cause rotation of pointers by means of an armature disk normally locked but released simultaneously with the excitation of the electromagnet. The engine-driven shaft C can be clutched when desired to the instrument spindle B which drives the electro-magnet F. The armature disk F' is held normally by a spring G<1> out of contact with the magnet and is prevented from rotating by a tooth K<3> on the armature K<1> of an electro-magnet K. When the magnet F is energized, the tooth is simultaneously withdrawn and the disk F<1> is rotated and turns a pointer H and through an eccentric G<2>, pawl arm J, and a pawl J<1> a second pointer H' which registers the number of the revolutions of the pointer H. In order to reset the pointers after a test has been made, a plunger rod L is depressed, and this causes a pivoted spring-controlled arm M to zeroize the pointer spindles by rotation of the heart cams J<4>, G<3>. This arm M is normally held raised by a hook M<4>, which is shifted to release the arm bv a projection L<2>. Other projections on the rod L throw out the tooth K<3>, the pawl J<1> and the detent J<5>.

Abstract: 9944. Mewes, R. April 28. Separating g a s e o u s mixtures by liquefaction. - In a process for liquefying and separating the constituents of air and like gaseous mixtures by means of approximately adiabatic expansion and primary cooling of the incoming gas by the expanded gas in heat - interchangers, (1) the gas is expanded with the production of external work to below atmospheric pressure, and (2) separation is effected by rectification of liquid formed on the inlet side of the expansion device. Fig. 1 shows apparatus for carrying out the process in which, between a heat-interchanger a and an expansion engine c, a second heat - interchanger d is provided wherein the expanded gases pass downwards in countercurrent with the unexpanded gas, which is partly liquefied thereby. The liquid trickling down the walls of the tubes g is rectified by the ascending gases. The expanded gases are drawn off from the interchanger a by a suction pump (not shown). In a modification, the unexpanded gases pass from the interchanger a to the interchanger d through a passage located above the lower ends of the tubes g instead of below as shown. Fig. 3 shows an apparatus in which the interchanger d is replaced by a rectification column furnished with layers of glass beads. The unexpanded gas and expanded gas pass upwards and downwards respectively through coils i, h the convolutions of which alternate as shown. The contents of the column are thus alternately heated and cooled throughout by the contents of the coils. The contents of the coil i are discharged into the column, mostly in the form of liquid air, through the inlet l. Approximately, gaseous nitrogen only passes from the column by the pipe m, to the expansion engine. Refluxes of liquid nitrogen, and a liquid approximating possibly to liquid air, are provided by means of gases taken from the top and bottom of the column respectively and passed through coils v, y<1> located in a cooling-chamber y traversed by the expanded nitrogen, these coils preferably terminating in the column in liquid-sealed ends v<1>. In a simpler form of apparatus, these refluxes are suppressed. Fig. 4 shows an apparatus in which the interchanger or rectifier comprises upper and lower portions d, d<1>. This permits of pure liquid oxygen being readily obtained in the base of the lower column.
