Title: Improvements in taps or valves
IPC: F16K21/10
Filed: 1926-10-15
Abstract: 260,251. Sircar, J. P. Oct. 23, 1925, [Convention date]. Valves closing after predetermined interval or flow.-A waste-preventing valve is provided with means for compressing a spring against the valve proper, or part connected thereto, and with means, such as a bellows device, for retaining it against sudden expansion so that the valve can then be opened and thereafter allowed to return gradually to its seat under the expansion of the spring. In the arrangement shown in Fig. 1, in the initial compression of the spring J the bellows K, formed of corrugated metal diaphragms is collapsed, water passing out through the non- return valve I; the valve N is then opened by a direct pull on the spindle C. Water gradually enters the bellows through the screw-controlled orifice H and closes the valve in a regulated time. The main supply is also controlled by a ferrule l having an opening of definite size. Fig. 2 shows a modification, operated by a lever c, in which the bellows is on the side of the seating remote from the valve N, the bottom G of the bellows being connected by a frame R to the valve spindle. The lever c compresses the spring by forcing down the upper end F of the bellows by engaging a pin P on an extension Q mounted on the end F.

Title: Improvements in rotary compressors and engines
Inventor: CHILTON ROLAND
IPC: F01C3/02
Filed: 1948-10-04
Abstract: 649,412. Rotary engines and compressors; gas turbines. STEVENS, A. H. (Wright Aeronautical Corporation). Oct. 4, 1948, No. 25803. [Class 110(ii)] [Also in Group XXII] A rotor 10 is provided with helicospiral vanes 16 which. with abutments 43 on discs 42, form working chambers diminishing in capacity from the rotor periphery radially inwards. The vanes 16 may be hollow, Fig. 1, and have cooling fluid passed through them. A stator 22, supporting the discs 42, is toric-shaped to fit closely to the vane tips, between the discs. The latter ,are driven by main gears 74, 72 frcm the main shaft 76, and from a shaft 66 coupled to the discs through bevel gearing. The stator 22 is built up of segments 32, which carry the discs and their driving mechanism, and segments 34, surrounded by a band 38 secured by bolts 40. The disc axes are tangential to the pitch circle 14 of the toric stator t. The disc shafts 48, 78, carry end flanges 50 and nuts 52 to clamp nut members 54, 56 and the bevel gears in position. Each disc 42 is formed in two halves to facilitate assembly, the halves being secured between the members 54, 56 by screws 62. Each bevel gear 58 meshes with a bevel gear 64 formed integrally with the shaft 66 and gears 60, 84 mesh together. In the construction shown the speed ratio between the rotor 10 and each disc 42 is 12 : 8 to prevent contact between the vanes 16 and disc teeth 43. Labyrinth packings 112, carried by walls 33, 35, minimize leakage of working-fluid, or fluid being compressed, radially inwards. When operating as a compressor the rotor 10 turns anti-clockwise, Fig. 3, and fluid which enters an annular inlet 24 is compressed in the diminishing chambers and discharged through an annular outlet 26. The compression ratio may be varied by varying the number of abutment discs, with increase in the number of vanes 16 and/or increase in the angle subtended by each vane about the rotor axis between the peripheral and minimum diameter of the rotor. Lubricating oil, for the bearings and gears, is supplied through ducts 94, 96, 98, 100. Seals 102 prevent leakage of oil to the discs 42. To balance the axial thrust on the rotor 10, fluid under pressure passes through openings 102 into a chamber 104. Two rotors may be arranged back-to-back for balancing purposes. When the apparatus operates as an engine, high-pressure fluid is supplied through the duct 26. Cooling air may be admitted into a shaft extension 76 and flows into the vane interiors through holes 108 and discharged through holes 110. Where the compressor supplies a gas turbine, compressed air collected by a manifold 114 may be led to passages in or between the turbine blades for cooling purposes. As a rotary engine the apparatus may be used as a starter for aircraft power plants, such as gas turbines. Means to machine the rotor disc, and form the vanes, are described in the Specification.

Patent GB-259899-A (GB)
Abstract: 259,899. CadgÞne, E., (Assignee of Rivat, G.). Oct. 15, 1925, [Convention date]. Yarns and threads, treating with liquids.- Textile materials composed of or containing cellulose acetate, are rendered capable of absorbing the weighting agent by treatment with acetic or formic acid or other agent having the effect of causing a swelling of the cellulose acetate fibres. The treatment with the swelling agent may take place either before they are treated with the tin chloride solution, or a solution of a salt of any other heavy metal; or alternatively it may take place during such treatment, for example by adding acetic acid to the tin salt solution. After treatment with the tin salt solution, the material is washed, and it may be again treated with the swelling agent and then further treated for fixing of the weighting agent, for example the tin salt may be fixed by treatment with a sodium phosphate bath. After the fixing, the material may be treated with silicate of soda. The weighting process may be repeated one or more times according to the loading desired. The weighted materials show an enhanced affinity for dyestuffs, particularly S.R.A. colours.

Abstract: 1,027,124. Transistor pulse circuits. SIEMENS & HALSKE A.G. June 25, 1964 [June 25, 1963], No. 26224/64. Heading H3T. [Also in Division G4] In a system for reading data from a magnetic tape (see Division G4) a circuit (Fig. 2, not shown) is effective to detect the absence of a clock pulse in a clock pulse train associated with the read data bits. The clock pulses are applied to switch a magnetic core K1 thereby rendering a transistor T3 briefly conductive to charge a capacitor C thereby switching a trigger circuit comprising transistors T1, T2 to a state with transistor T1 blocked. If, due to the absence of an input clock pulse, the capacitor C becomes discharged, the trigger circuit T1, T2 changes over thereby switching a magnetic core K2 to cause a transistor T4 to produce an output or alarm signal at AL which may be effective to replace the missing pulse by opening a gate to pass a pulse from an auxiliary train (Fig. 1, not shown). A thermistor Th renders the time constant of the circuit R, C independent of temperature changes.

Title: Process for dyeing cellulose fibres with direct-dyeing azo-dyestuffs containing copper or nickel in complex union
IPC: D06P3/64
Filed: 1951-11-09
Abstract: Cellulose fibres are dyed with direct-dyeing azodyestuffs containing copper or nickel in complex union, in the presence of an aliphatic amine having at least 2 nitrogen atoms each bound to 2 carbon atoms and having at least 2 hydroxyl groups, e.g., amines of the general formula <FORM:0708144/IV(c)/1> in which R1 is hydrogen or an alkyl group having at the most three carbon atoms or a hydroxymethyl group, R2 is hydrogen or a methyl group, and n is a whole number at the most 4 but preferably 2.  The amine has a strong restraining action on the dyestuff and equilibrium is attained very rapidly, and at any given amine concentration, quantity of dyestuff and quantity of material to be dyed, the restraining action is constant and independent of the liquor ratio.  Aldehydes may be added, if necessary, to restrain the action of the amines.  Unlevel dyeings or too strong dyeings which have been produced with cupriferous dyeings by the customary processes may be treated in a bath containing the amine to remove the excess or a greater part of the dyestuff, after which formaldehyde may be added to restrain the action of the amine and the dyeing repeated, if desired, using the dyestuff that is present in the bath. The maximum action of the amine is usually obtained at a concentration of 3 grams per litre.  In Example (1), cotton is dyed in a bath containing sodium sulphate, 1, 2-di (b -oxyethylamino)-ethane and the copper compound of the dyestuff obtained from diazotized 2-amino-1-oxybenzene-4-sulphonic acid amide and 5, 5\sv-dioxy-2, 2\sv-dinaphthylamine-7, 7\sv-disulphonic acid, and formaldehyde is then added in several portions.  By omitting the formaldehyde a weaker dyeing is obtained but several successive and equal dyeings may be made in the same bath.  Several alternative dyestuffs are specified, and a table is given showing how the strength of the dyeing depends on the concentration of the amine.  In Example (2), cotton dyed with the copper complex of the disazo dyestuff from diazotized 2-amino-1-oxybenzene-4-sulphonic acid and 5, 5\sv-dioxy-2, 2\sv-dinaphthylurea-7, 7\sv-disulphonic acid is entered into a bath of 1, 2-di-(b -oxyethylamino)-ethane at the boil whereby the dyestuff is practically completely removed; on adding formaldehyde to the bath, the dyestuff is again taken up by the fibre.  In Example (3), cotton is dyed in a bath containing the nickel complex of a dyestuff having the formula <FORM:0708144/IV(c)/2> sodium sulphate and 1, 2-di-(b -hydroxyethylamino)-ethane at the boil, followed by the addition of formaldehyde.  Specification 676,584 is referred to.

Abstract: 627,579. Valve circuits for radio reception ; radiolocation. BEVERIDGE, H. N. Sept. 5, 1946, No. 26730. Convention date, Sept. 12, 1945. [Classes 40 (v) and 40 (vii)] A detector circuit which is capable of linear operation over a very wide range of input amplitudes comprises a first rectifier 40 and an auxiliary rectifier 25. At low input levels at which the diode 40 would be non-linear it is rendered inoperative by means of a delay bias applied over resistances 37, 41 and the signal is amplified by a valve 10, linearly rectified by the diode 25 and restored to the proper level by a potentiometer comprising resistances 35, 36. At higher levels the diode 40 is operative and rectification by the diode 25 ceases due to limiting taking place in the valve 10. A modification of the arrangement (Fig. 2, not shown), is intended for an echo-ranging or impulse communication receiver to permit of clear reception in the presence of interference by continuous waves ; it follows the normal signal detector and is used to rectify the beat note produced between the detected signal pulses and the interference. In the modified arrangement the valve 10 is connected as an audio frequency amplifier and is fed from the anode circuit of an additional preliminary amplifier. The diode 40 is fed from the cathode circuit of the preliminary amplifier in order to preserve the phase relationships of the output irrespective of which of the diodes is operative.

A battery charging circuit comprises voltage dividing resistors R1, R2 connected at the midpoint 4 to the base of a transistor TR1 forming with a transistor TR2 a Schmitt trigger circuit controlling a current amplifying transistor TR3. The circuit is arranged so that when the battery reaches a determined voltage, just short of the gassing point, the potential at point 4 relative to the conductors 3 causes TR1 to conduct and TR2, TR3 to block, but as the battery voltage falls this state is reversed and charging proceeds in a series of small intervals of decreasing current magnitude (see Fig. 3, not shown). In a modified circuit, Fig. 6 (not shown), a load may be alternatively supplied through a switch SW1-5. In position a the load voltage, as measured across C2, VR is maintained constant by transistor TR3. On failure of the supply the battery supplies the load in an uncontrolled manner through a transistor TR6 switched to its conductive state. The battery is not charged through TR6 due to its unidirectional properties. When the battery voltage falls to a determined discharge value, transistors TR4-6 block and this circuit must be reset, but in a modification, Fig. 9 (not shown), when the battery voltage recovers the circuit is again supplied until the battery voltage falls again. In switch position b the load is disconnected and the circuit is reconnected to charge the battery in a manner as described in connection with Fig. 1A. A number of other arrangements are described in the Specification.
