摘要:
A solenoid valve has a housing in which is disposed a coil, a sleeve valve and a plurality of hydraulic fluid passages. The passages are formed in a cylindrical core which is integral with and extends axially from an end wall of the housing. The sleeve valve is slidably mounted on the core and has a pair of annular recesses which are selectively positionable by valve movement to interconnect various combinations of passages for controlling hydraulic fluid flow. The sleeve valve has a metal ring secured thereto so that the sleeve valve will be moved in response to electric current flowing in the coil which surrounds a portion of the sleeve valve.

A process of dyeing textile fibres in which the fibre is contacted with a two-phase suspension comprising an active solvent containing dissolved dye and the necessary amount of a bulking inert substantially immiscible solvent, the active solvent under the conditions of dyeing being liquid, is a solvent for the dye, is insoluble or only slightly soluble in the inert solvent, and in which the fixation affinity of the fibre for the dye is greater than that of the active solvent for the dye at the temperature required for the fixation, wherein the dye used is in the form of an aqueous, stable, highly concentrated, finely dispersed, flowable preparation insoluble to difficultly soluble in water containing at least 25% of finely dispersed dyestuff, at most 10% of an anion-active dispersing agent, at most 5% of a non-ionic dispersing agent and from 0 to 35% of a hydrotropic agent.
摘要:
A process for dyeing textile fibres which comprises contacting the fibre with an active solvent containing dissolved dye in admixture with the necessary amount of a bulking inert substantially immiscible solvent, the active solvent under the conditions of dyeing being liquid, a solvent for the dye, insoluble or only slightly soluble in the inert solvent, and in which the fixation affinity of the fibre for the dye is greater than that of the active solvent for the dye at the temperature required for fixation.
摘要:
A particulate composition useful in the softening of fabrics from a wash liquor, the composition comprising a fabric softening clay material and a nonionic surfactant system which consists of one or more nonionic surfactants, wherein the nonionic surfactant system exists as a cloudy phase, at 1% concentration in water, somewhere in the range of 0.degree. C. to 80.degree. C., the weight ratio of the clay to the nonionic surfactant system is from 2:3 to 20:1, and the moisture content of the composition, as measured by the water loss at 135.degree. C., is from 7.5% to 12% by weight.
摘要:
An improved process for dyeing of fibre material, especially textile fibres, by applying to the fibre material at a temperature below the absorption temperature of the dyestuffs and with a goods-to-liquor ratio of 1:1.5 to 1:4, a concentrated aqueous dye liquor, said concentrated aqueous dye liquor containing at least one dyestuff which, in the case of the substrate to be dyed, has affinity to the fibres and which is either soluble or dispersible in water, and 0.2 to 10 g/l, preferably 2 to 5 g/l, of a surface-active agent, and finishing of the dyeing by means of a heat treatment, e.g. introduction of saturated steam, superheated steam or hot air, preferably by heating from without, at temperatures of 95.degree. to 140.degree. C.

摘要:
An apparatus and method of controlling a remelting process by providing measured process variable values to a process controller; estimating process variable values using a process model of a remelting process; and outputting estimated process variable values from the process controller. Feedback and feedforward control devices receive the estimated process variable values and adjust inputs to the remelting process. Electrode weight, electrode mass, electrode gap, process current, process voltage, electrode position, electrode temperature, electrode thermal boundary layer thickness, electrode velocity, electrode acceleration, slag temperature, melting efficiency, cooling water temperature, cooling water flow rate, crucible temperature profile, slag skin temperature, and/or drip short events are employed, as are parameters representing physical constraints of electroslag remelting or vacuum arc remelting, as applicable.
摘要:
An air/fuel ratio controller for an internal combustion engine including two memories each having numbers stored at locations addressed by engine operating points with the locations addressed by the engine operating points being updated during closed loop operation in accord with the value of a closed loop adjustment of the air/fuel ratio. Each memory location in the first memory is updated during operation of the engine at the corresponding operating point in accord with an update time constant having a value so that the number stored tracks adjustment value producing the predetermined desired closed loop air/fuel ratio during varying values of engine operating parameters. Each memory location in the second memory is updated during operation of the engine at the corresponding operating point in accord with an update time constant having a value so that the number stored is the average of the values producing the predetermined closed loop air/fuel ratio during varying values of engine operating parameters. The first memory is used during closed loop operation to preset the closed loop adjustment at least when the engine first operates at an operating point and the second memory is utilized during open loop operation to adjust the air/fuel ratio by an amount determined at least in part by the number stored in the second memory at locations addressed by the engine operating point.
