Abstract: A method for treating natural textile fibres and synthetic polyamide fibres to enhance their affinity for disperse dyestuffs which comprises treating the fibres with an aqueous solution or dispersion of an arylating agent. The arylating agent contains both a benzene or naphthalene ring and a reactive group, such as a halo-triazine group. The fibres may be treated by exhaustion from long liquors or by padding, and the affinity for disperse dyestuffs is considerably increased thereby.

Abstract: A method of controlling a hydraulic actuator which controls the rotational phase angle of the fuel injection pump for the automobile. A satisfactory exhaust gas composition and an appropriate fuel consumption during a warm-up period of the engine are achieved when the oil temperature in the hydraulic actuator is low. The control method for the hydraulic actuator includes the steps of detecting the temperature corresponding to the oil temperature, comparing the detected temperature with the predetermined reference temperature, and making the application period of the command pulse signal for driving the hydraulic actuator longer than the predetermined length when the detected temperature is lower than the predetermined reference temperature.

Abstract: An impact-activated toy suitable for use in a child's crib which is capable of generating a series of melodies in response to successive impacts by a child spaced by more than, for example, ten minutes from the termination of the preceding melody. A momentary push-button switch for the mother's use is provided to cause the toy to generate a series of melodies in response to actuation by the mother when no melody is being generated or to stop the generation of any melody being generated at the time of the switch actuation.

Abstract: An improved infusion bag for preparing an infusion of tea or other infusible substances, comprising a sachet member of liquid-permeable sheet material and a pull string. The pull string is joined at the upper apex of the sachet. At least one ventilative slit is provided below the joint point of the string and the upper apex of the sachet. The sachet can be folded into a generally tetragonal shape. After steeping, and by the action of withdrawing and submerging, the infusible substance swells and sinks to the lower apex of the sachet. The improved infusion bag makes the infusible substance less compacted and overcomes the constraint due to the capillarity of the liquid-permeable sheet material itself and the interface capillarity of the mass of the infusible substance. This gives a higher quantity and higher concentration of infusion liquor.

Abstract: A method for activating a methanol synthesis catalyst is disclosed. In this method, the catalyst is slurried in an inert liquid and is activated by a reducing gas stream. The activation step occurs in-situ. That is, it is conducted in the same reactor as is the subsequent step of synthesizing methanol from a methanol gas stream catalyzed by the activated catalyst still dispersed in a slurry.
