Title: New imidazoline salts and hydrocarbon fuels containing same
IPC: C23F11/14
Filed: 1962-04-27
Abstract: The invention comprises salts of a 1, 2-disubstituted imidazoline and a carboxylic acid, the imidazoline having the formula: <FORM:0958160/C2/1> and the carboxylic acid containing the group <FORM:0958160/C2/2> linked to a carboxylic group by a chain of at least 2 carbon atoms, R and R1 being open-chain hydrocarbon radicals having 8-22 carbon atoms.  The salts may be prepared by reacting equimolar amounts of the 1, 2-disubstituted imidazoline and the appropriate acid.  Suitable acids are, for example, succinamic acids of formula: <FORM:0958160/C2/3> and citrimic acids of the formula: <FORM:0958160/C2/4> The reaction may be carried out in a solvent, e.g. isopropyl alcohol.  The 1, 2-substituted imidazolines may be prepared by reacting the corresponding acid (R1COOH) with N-hydroxyethyl ethylene. The succinamic acids may be prepared by the reaction of equal amounts of an amine (RNH2) with succinic acid and the N-substituted citrimic acids by reaction of an amine (RNH2) with citric acid.ALSO:New salts of 1,2-disubstituted imidazolines, of formula <FORM:0958160/C3/1> and a carboxylic acid containing a group <FORM:0958160/C3/2> linked to a carboxylic group by a chain of at least 2 carbon atoms, R and R1 being openchain hydrocarbon radicals having 8-22 carbon atoms, are used as corrosion inhibitors in hydrocarbon fuels.  They may be added, for example, to blended gasoline, heater oil, a jet or diesel fuel, a furnace oil, kerosene or gas oil.  Other additives, for example tetraethyl lead, may also be present.  Suitable salts are, for example, 1-(2-hydroxyethyl)-2-heptadecenyl imidazolinium N-tallow succinanate or citrimate, and 1-(2-hydroxyethyl)-2-tallow imidazolinium-N-oleyl citrimate.  They are preferably used in an amount of from 0.0001 to 0.0015% by weight and may be added in the form of a concentrate in a hydrocarbon fuel or a suitable solvent such as xylene, toluene, benzene, phenol, isopropyl alcohol, ethanol and n-butanol.

Title: Improvements in picking mechanism for looms
IPC: D03D49/46
Filed: 1921-06-14
Abstract: 184,319. Menzies, W. June 14, 1921. Picking-motions; shuttles; shuttle boxes.-In a positive picking-motion in which the shuttle is handed across the shed by bars, the bars enter into grooves in the shuttle and engage catches on the shuttle, while other. fixed catches throw the shuttle catches out of action as required. The bars 19, 20, Figs. 1 and 3, are reciprocated by grooved cams 3 operating on levers 6, 7. The shuttle with a sliding and catch-releasing plate 47 is shown in side elevation in Fig. 6, and in side elevation with the plate removed in Fig. 7. In operation, assume that the reduced end of the bar 19 is in the groove 33, and retained by engagement of the catch 39 with the wedge-shaped catchblock 27, Fig. 4, on the bar 19, the movement being to the left. Just before reaching the ex. treme left position, a spring-pressed catch 29 on the lay engages a stud 49 on the plate 47, thus sliding the plate 47 a little to the right, relative to the shuttle. The plate has an incline 52, which engages the spring catch 39 to disengage it from the catch on the shuttle-bar 19. The bars 19, 20 then move towards the centre, the bar 19 merely carrying the shuttle to the centre, where the reduced end of the bar 20 enters the groove 34 and is engaged by a similar catch 38. On the bars separating, the shuttle is carried to the right by the bar 20, the bar 19 being free to withdraw from the shuttle. The bars 19, 20 move in slides 23, 24, which in turn can slide within guide-bars 25, 26 on the lay.

Filed: 1961-05-08
Abstract: 924,307. Friction clutches; clutch combinations; ratchet clutches. ZAVODY 9. KVETNA NARODNI PODNIK. May 8, 1961 [May 11, 1960], No. 16708/61. Addition to 919,296. Class 80 (2). In a centrifugal friction clutch of the parent Specification, wherein lined clutch shoes 1 having conical friction surfaces and pivoted on a driving carrier 9 are centrifugally moved to an extent limited by stops 5, against return springs 8, to engage corresponding friction surfaces of one or two driven clutch plates (not shown), means providing a centrifugal disengaging speed, e.g. 1200 r.p.m., substantially below the centrifugal engaging speed, e.g. 1800 r.p.m., comprises masses 12 pivoted at 14 on the carrier 9 between the clutch axis 11 and the shoes and having return springs 18, shoeengaging arms r<SP>1</SP>, the length of which is equal to but not less than the radial distance between the pivots 14 and the inner surfaces of the shoes when the latter are fully expanded, and centres of gravity arranged to one side of the arm, and limit stops 16 on the shoes providing that in their outermost mass position the arms r<SP>1</SP> are, in the extreme case, radial to the clutch axis 11, such that the speed at which the moment of centrifugal force acting on each mass equals the moment exerted by its return spring 18 is less than the speed at which the moment of centrifugal force acting on each shoe equals the moment exerted by its return spring 8. The carrier and driven clutch plates are axially spring-loaded and disengagement at any speed may be effected by axial plate separation. As carrier 9 accelerates, the masses 12 swing out faster than the shoes 1 until their arms r<SP>1</SP> contact the shoe inner surfaces. The masses are relatively small and do not substantially affect shoe expansion so that the engaged position of the parts shown is not reached until the engaging speed (e.g. 1800 r.p.m.). When the speed falls below the engaging speed the centrifugal moment on the masses exceeds their return spring moment so that the masses prevent shoe retraction until the speed at which the moment exerted by the return springs 18 exceeds the combination of the moment of centrifugal force of the masses and the moment of the frictional force due to the load of the shoe return springs on the masses. As the masses begin to return, the friction between the shoes and the masses changes from static to dynamic and an additional moment due to the load of the shoe return springs on the masses assists the mass return spring moment with increasing effect to allow abrupt shoe retraction. The stops 16 may be arranged to arrest the masses in positions short of, but not beyond, the radial position of the arm r<SP>1</SP> shown, in order that the masses will be subject to a shoe return spring moment at all speeds below the engaging speed.

Title: Improvements in or relating to methods of chemically treating apparatus, particularlysteam generators
IPC: C23F11/00
Filed: 1962-05-04
Abstract: Apparatus, such as steam generators with natural of forced circulation, is chemically treated with at least one inhibitor in a treating agent in which the agent is heated in the apparatus and nowhere to more than the normal boiling temperature, the static pressure in the apparatus being adjusted so that nowhere does the boiling pressure exceed the normal pressure.  The treating agent comprises a circulating solvent containing dissolved chemicals, e.g. de-scaling with acid in a solvent, which may both clean and treat the apparatus, the pressure within said apparatus being reduced e.g. to 0.3 atm., so that the boiling temperature at the lower fluid levels does not exceed normal atmospheric boiling temperature.  To obtain adequate circulation of the chemical solutions, particularly with natural circulation boilers, reduced pressure boiling at below normal boiling temperatures is effected throughout the apparatus by controlled heating, e.g. by an electric immersion heater.  The circulatory flow in the apparatus can be mechanically or pneumatically assisted.  If superheaters, intermediate superheaters and economizers are connected to a boiler the agent can be circulated through these.  The invention is further said to be applicable to the treating or cleaning of evaporating plant, waste heat utlizers and heat recovery plant.
