Title: Surface active compositions
IPC: C11D1/72
Filed: 1963-05-16
Abstract: Surface-active compositions comprise by weight (1) 65-95% of an alkali soluble phosphorylated surfactant which is the reaction product of a polyether R(CH2CH2O)xH, wherein R = C10-C15 alkoxy or is a phenoxy group having one or more C4-C10 alkyl substituents, x, or the number average of x, is 5-25, and a phosphorylating agent which replaces terminal OH groups by primary phosphate groups; (2) 5-35% of an aminated surfactant of the formula <FORM:1021392/C4-C5/1> where R1 = C10-C15 alkoxy group or is a phenoxy group having one or more C4-C10 alkyl substituents; R2 and R3 are hydrogen or alkyl groups, the total number of carbon atoms in the alkyl groups being 7 or less, and z, or the number average of z, is 4-25.  Preferably R and R1 each are t-octylphenoxy groups and R2 and R3 are methyl groups.  The compositions are prepared by (a) blending the prepared constituents or (b) phosphorylating a mixture of the appropriate polyether and the aminated surfactant. Phosphorylation takes place at 80-110 DEG  C. using 1 to 2 moles of polyphosphoric acid per mole of surfactant or 1 to 2 moles per hydroxy group present in the mixture when method (b) is used. Discoloration of the reaction product may be prevented by the presence of hydrogen peroxide or hydrazine hydrate in the reaction mixture.  The above compositions may be combined with 88 to 99% by weight of an alkaline material to provide cleaning compositions which are water-soluble.  Specified alkaline materials are sodium meta-silicate, sodium orthosilicate, soda ash, trisodium phosphate, sodium polyphosphate, tetrasodium pyrophosphate and tetrapotassium pyrophosphate.ALSO:Surface-active compositions comprise by weight (1) 65-95% of an alkali soluble phosphorylated surfactant which is the reaction product of a polyether of general formula R(CH2CH2O)xH, wherein R is a C10-C15\t alkoxy group or a phenoxy group having one or more C4-C10 alkyl substituents, x or the number average of x is 5 to 25, and a phosphorylating agent which replaces terminal OH groups by primary phosphate groups; (2) 5-35% of an aminated surfactant of general formula <FORM:1021392/C3/1> wherein R1 is a C10-C15 alkoxy group or i a phenoxy group having one or more C4-C10 alkyl substituents, R2 and R3 are hydrogen or alkyl groups, the total number of carbon atoms in the alkyl groups being 7 or less and z or the number average of z being 4 to 25.

Patent GB-358431-A (GB)
Title: Improvements in and relating to methods of and apparatus for treating sulphur dioxide
IPC: C01B17/56
Filed: 1930-07-01
Abstract: <PICT:0358431/III/1> Sulphur dioxide is purified from sulphur trioxide by passing the gas through finely divided sulphur or finely divided sulphur which has been fused with bentonite, carbon black or other substance with a large surface which does not enter into chemical combination with sulphur, the reaction proceeding at room temperature.  Alternatively, the purification can be effected by passing the gas through finely divided selenium sulphide preferably maintained at 80-85 DEG  C.  The sulphur trioxide is reduced to sulphur dioxide by the sulphur or selenium sulphide. After a period of use the activity of the finely divided sulphur may be restored by heating it to 75-80 DEG  C. preferably an inert gas being passed over it at the same time.  The activity of used selenium sulphide may be restored by grinding the material.  A suitable purifying unit is shown in the Figure.  The impure but preferably dried sulphur dioxide enters at 10, passes upwards through the purifying material 29 situated in the annular space 4, the purified gas leaving at 21.  The temperature of the purifying material is controlled by a water jacket 1.  A battery of such units may be employed.  Specification 350,739, [Group XII], is referred to.

Title: Improvements in selecting devices for coins and tokens for coin freed machines and other uses
Filed: 1938-07-06
Abstract: 504,689. Testing coins. LABOUROT, L. C. July 6, 1938, No. 19995. Convention date, July 12, 1937. [Class 27] A device for selecting coins for coinfreed machines and other uses comprises a runner 6, Fig. 1, slidable on a guide 3, 4 mounted on a front plate 1 having an aperture 11 through which the runner passes. The coin is placed with its effigy uppermost in an aperture 7 in the runner which is pushed in carrying the coin with it until the coin comes over a disc 26, Fig. 4, on the end of a lever 23 which is hinged at 22 to a carriage 16 slidable on a dovetailed guide 17. A spring 24 urges the lever 23 upwardly and normally holds tlie carriage 16 against the front plate 1. Further inward movement of the runner moves the carriage 16 inwardly so that the end 27 of the lever 23 disengages an incline 28 on the guide 3 and is moved up until a lug 29 thereon abuts against the carriage. This movement presses the top of the coin against projections 14 on feelers 12 pivoted at 13 to the carriage and guided by grid 21. If the coin is correct the fillersare moved 'varying distances so that their free ends can pass through staggered slots in a plate 31 adjustably secured to a flap 32 which is pivoted at 33 to the fixed guide 17. The disc 26 is provided with small points to engage the lower surface of the coin. Further inward movement of the carriage causes an upstanding lug 40 on the lever 23 to meet an arm 38a of a lever 38 which is pivoted at 39 to the guide 17 and which is also connected by a pivot pin 36 to an arm 35 integral with the flap 32. The lever arm 38a causes the lever 23 to rock downwardly to discharge the coin to a shoot 2 leading to the releasing mechanism of a coin-freed machine or to a receptacle. If the coin is not correct, the feelers 12 will not be moved the proper distance and so cannot pass through the plate 31 which will be rocked to move the lever arm 38a out of the path of the lug 40. The lever 23 accordingly will not be rocked and the incorrect coin is returned by pulling out the runner to its initial position.

Title: Improvements relating to asphaltic and bituminous compositions
IPC: C08L95/00
Filed: 1933-07-17
Abstract: Fresh Florida bleaching-earth (Florida decolourizing clay), as used for refining and decolourizing in the petroleum industry and for refining mineral lubricating oils, is incorporated in bituminous and asphaltic compositions.  The earth may be activated prior to use, as by heating or acid treatment or both. Examples are given showing how the addition of the earth to usual bituminous compositions results in a hardening of the latter. Thus in one example a mixture containing 9 to 11 per cent epur<\>ae, 9 to 11 residual petroleum bitumen, 5 to 6 Florida bleaching earth and 70 to 75 powdered limestone, has a hardness number 15 compared with a hardness number 30 to 40 for a mixture containing no earth but otherwise identical therewith.  The petroleum bitumen and epur<\>ae are melted together and incorporated with the earth, preferably in vertical mixers.  This composition is then incorporated with the limestone in horizontal mixers.  This mixture may be mixed with 30 per cent of its weight of granite chippings for paving purposes.  Other examples are given in which sand and natural rock asphalt are used as the principal constituents. Specification 372,755 is referred to.

Title: Improvements in or relating to safety devices for appliances making, using, treatingor purifying combustible gases
Inventor: MACCORMAC MICHAEL
IPC: C10J3/72
Filed: 1952-08-13
Abstract: <PICT:0729935/III/1> Apparatus for testing a combustible gas and for protecting apparatus (e.g. electrostatic detarrers) in which an explosion may occur if the proportion of oxygen in the gas is too high, comprises an igniting means within a conduit conveying gas to the apparatus to be protected, a chamber surrounding the igniting means and open at both ends, a second conduit conveying air to the chamber, and a flame detecting device in the chamber adapted, should the flame spread away from the igniting means, to operate a warning or indicating device or to shut down the apparatus, and to stop the supply of air to the chamber, remove the igniting means, and extinguish the flame.  As shown, air is introduced at 26 through chamber 15 and duct 14 into chamber 28 where it mixes with gas entering from the main conduit through an inlet port in chamber 28; the mixture passes to flame chamber 11 in which is arranged a shrouded pilot jet 16 supplied with air from inlet 27 via conduit 25. If the gas contains too much oxygen, the flame spreads and burns or melts a combustible or fusible thread 23, thus releasing spring-loaded mercury switch 24 which operates warning and safety devices.  Other suitable igniting means are a small combustion chamber of the type described in Specification 535,482, [Group XIII], supplied with air and gas, an electrically heated wire, an electric arc, a spark gap, or an electric discharge produced between a high tension electrode and the earthed chamber.  The spread of the flame may also be detected by an electrical conductor sensitive to changes in temperature, by an electronic device in which the ionizing effect of the flame enables current to flow between two electrodes, or by making the combustible thread itself part of an electrical circuit which when broken operates the safety device.  The pilot jet may be lit by means of an incandescent wire, an electric arc, a spark gap, an ignition tube, or an explosion cartridge.  Means may be provided to give warning or actuate the safety devices if the igniting means is inoperative; such means may include a brinetallic strip, a thermocouple, an electronic conductor sensitive to changes in temperature, or an electronic device.  The testing apparatus may be surrounded by a water or steam jacket to keep the thread dry and free from tar deposits.  In order to extinguish the flame when the safety device operates, the chamber and the conduit are purged with a fire or explosion suppressing substance, e.g. steam, carbon tetrachloride, methyl bromide, or carbon dioxide, as described in Specification 643,188, [Group XXI].  The apparatus may be used in conjunction with a differential pressure switch actuated by pressure drop across the detarrer, and with a burner of the type described in Specification 676,282, supplied with gas from the outlet of the detarrer.

Abstract: 587,021. Controlling hydro-mechanical changespeed gearing. EVERNDEN, H. I. F. Oct. 20, 1944, No. 20396. [Class 80 (ii)] The actuating pressure of a friction controlling- element, such as a clutch or group of brakes 8a, b, c of a change-speed gear B, is augmented by the torque-reaction on the guide-ring 3 of a hydrokinetic torque-converter A through which the change-speed gear is driven, so that additional friction pressure is available at the controlling-element at times when the torque demand is greatest. The controlling band-brakes 8a, b, c of the three-speed epicyclic gear shown are operated by separate hydraulic pistons 12, under control of a manual distributer-valve 26, which is normally supplied with pressure oil by pumps 14, 15, the former driven by the turbine 3 of the converter, the latter by the rear-axle 10 of a motor-vehicle driven by the gear, the pumpsupply being subject to a pressure-relief valve 19. Pressure augmentation is effected by a spring-returned piston 24, which, under the influence of torque-reaction on the guide-ring 3 of the converter, is thrust downwardly in its cylinder 22 to increase the pressure in the line to the distributer-valve 26 and selected brakepiston 12, a non-return valve 20 preventing loss of such increased pressure through the pumpline. The distributer-valve line has a second pressure-relief valve 25 set at a substantially higher pressure than the pump relief-valve 19.
