Title: Improvements in and relating to motor cycles and other motor vehicles and friction transmission gears for same
IPC: F16H61/664
Filed: 1920-07-17
Abstract: 160,737. Neracher, C. A. March 26, 1920, [Convention date]. Controlling different functions by same handle or lever; setting and retaining devices.-Comprises controlling-mechanism for friction-disc variable gearing for motor-cycles &c. In the construction shown in Fig. 1, the roller 14 is pressed against the fly-wheel by a cable 37, and is moved inwards along its shaft to change the gear ratio by a foot-lever 25 operating a link 28 and a bellcrank lever 31. The roller is retained in the low-gear or intermediate position by a catch pivoted to the lever 25, this catch engaging with fixed teeth 34 and being released therefrom by pressure on a toe-piece 35. In the construction shown in Fig. 4, the roller is poved along its shaft by a link 51, and is pressed against the fly-wheel by a link 57, both links being operated by a single hand-lever 46 carrying a pin 49 engaging eyes in the two links. ' The roller tends to move to the edge of the fly-wheel under the action of a spring on the roller shaft, the link 51, however, is normally restrained from movement in the corresponding direction by the engagement of a tooth 52 with fixed ratchet teeth 53. When the link 51 is lifted by upward foot pressure on a pin 54, the spring is free to act and moves the roller to the next higher gear position. A spring 58 tends to pull the roller away from the fly-wheel. When the hand-lever 46 is moved to the left it operates both links and disengages the gear while shifting the roller to the low-gear position. When the lever is moved to the right it operates the link 57 only and causes the roller to engage the fly-wheel, giving the low-gear drive. Changes of speed are then effected by raising the foot-piece 54, so allowing the roller spring to act.

Title: Valve for pressure fluid flow control
Inventor: HOWLETT REX RICHARD
IPC: F17C13/04
Filed: 1958-07-07
Abstract: 862,756. Valves. BRITISH OXYGEN CO. Ltd. July 6, 1959 [July 7, 1958], No. 21706/58. Class 135. [Also in Group XXVIII] A combined pressure-regulating and relief valve comprises a easing 10, Fig. 1, divided by an apertured partition 11 into a pressure chamber 12 and a secondary chamber 13 each provided with a flow port 25, 26, respectively, opening out of the casing, a movable valve member 15 having a longitudinal bore 16 therethrough being movable endwise with clearance in the aperture and being resiliently urged into fluid-tight engagement, so as to close one end of said bore, with a seating 19 carried by a resiliently-loaded flexible member or bellows 20 forming a wall of the pressure-chamber, the valve member 15 having a portion thereof which is in the secondary chamber formed with an annular seating member 28 capable of engagement with a complementary seating 30 surrounding the aperture in the partition, and the resilient loading of the flexible member 20 normally balancing the resilient loading of the valve member 15 with the annular seating member 28 held clear of the partition so as to open said aperture, the range of movement of the flexible member 20 being sufficiently greater than the clearance between the annular seating 28 and the seating 30 on the partition to provide for closing of the aperture in the partition followed by opening of the bore in the valve member 15. As applied to a converter system for liquified gas, Fig. 2, an initial gravity flow from a storage vessel 41 to a demand line 42 also supplies a pressure build-up circuit comprising an evaporating coil 45 so that the vessel 41 becomes pressurized on top of the liquid phase through the ports 26, 25 of the valve device and thence through a filler valve 47 and a conduit 48, whereby the line 42 is now supplied under an operating pressure head. This operating pressure is limited by closing of the aperture in partition 11, which stops communication between the gas phase and the liquid phase of the vessel 41 via the build-up circuit. Any further pressure increase occurring within the vessel 41 is relieved from the gaseous phase by opening of the upper end of the bore 16 of the valve member 15 and this gas passes a check-valve 31 seated on the other end of the member 15 and is fed back into the circuit to prevent wastage. To guard against an excessively high pressure occurring in the gas phase of the system a further relief valve 35 incorporated in the body 10 is opened by the bellows 20 on continued compression thereof acting through a spindle 40 to vent the pressure chamber 12 to atmosphere at 39. An additional relief valve 33 controling a by-pass between the two chambers of the valve device prevents excessive pressure from developing in the build-up circuit while the system is standing pressurized without demand on it, and also by maintaining a slight pressure differential of the liquid phase delivery side over the gas phase side under these conditions prevents loss of liquefied gas from the vessel 41 under gravity head.

Title: A process for manufacturing coloured cellulose material
IPC: C08L1/00
Filed: 1933-08-04
Abstract: Regenerated cellulose materials in the form of threads, ribbons, films, &c. such as are produced by the viscose and cuprammonium processes, are obtained directly in the dyed condition by adding to the viscose &c. solution an ester salt of a body yielding by acid oxidation a coloured compound, preferably an ester salt of a leuco vat dyestuff, the colour being developed by acid oxidation simultaneously with or subsequently to coagulation.  As an alternative, the cellulose solution containing the undeveloped ester salt may be applied to a fabric, and the colour similarly developed during or after coagulation of the effect coating.  In the case of cuprammonium solutions, coagulation and development of the colour may take place simultaneously under the influence of the cupric salt set free during the coagulation process; with viscose, the oxidising agent may be added to the coagulation bath, or an oxidising agent such as sodium nitrite which acts only in an acid medium, may be incorporated in the viscose.  To obtain particular effects, threads may be made up of a number of filaments differently dyed or even undyed; the undeveloped colour may be superficially removed from a thick thread or film by treatment with water; and the printing-reserve-discharge process may be employed.  The examples include processes for the production of coloured viscose and cuprammonium threads in which to the viscose &c. solution there is added a salt of the acid sulphuric ester of leuco-indigo, leuco-6 : 6<1> - diethoxyindizo, leuco - dimethoxydibenzanthrone, leuco - dibenzpyrenequinone, 3 : 3<1>-dichlor-1 : 2 : 2<1> : 1<1>-dianthronequinoneazine, 1 : 2 : 2<1> : 1<1> - dianthronequinoneazine, and of reduced b -aminoanthraquinone or a derivative thereof, and also of the dyestuffs from diazotised b  - amino - 3 - chloranthrahydro - quinone - disulphuric acid ester and b -oxynaphthoic-acidanilide; the colour is either developed in the coagulation bath, or more usually in a subsequent bath, suitable oxidising agents being sodium nitrite, bichromate, copper sulphate and ferric chloride.  Specifications 186,057, 203,681, 310,478, 312,404, [all in Class 15 (ii), Dyeing, Processes &c. for], and 383,741 are referred to.
