    Abstract: A method and apparatus for continuously pressure decatising a fabric include a rotatable drum (12) around which an endless belt (15) is arranged to travel for conveying a fabric (19) (and optionally a moisture laden textile (20)) between the facing surfaces of the belt (15) and the drum (12). The drum (12) is heated and fabric (19) is pressed between the belt and the drum as it is conveyed through the apparatus. The fabric (19) is subjected to pressurised saturated steam, which may be generated by evaporation of the moisture in textile (20) when it contacts the heated drum, as it is pressed. Various options other than use of a moisture laden textile (20) for supplying the steam are disclosed. The invention involves enclosing the drum in a pressure vessel (14) within which a compressed air atmosphere at ambient temperature is maintained. The surrounding compressed air atmosphere can be used to control the steam temperature, that is, the saturated steam temperature can be changed by changing the pressure of the surrounding compressed air. The surrounding compressed air atmosphere also reduces the sealing requirements for the steam treatment and belt wear. The method and apparatus are also applicable for setting staple fibres.

    Abstract: A laser marking apparatus for marking a moving workpiece such as a wire or cable directs a substantially constant rapidly pulsed beam of laser radiation in the U.V. band towards a low inertia, low mass rotatable mask with character apertures disposed around its periphery. The mask is driven asynchronously and slaved to the laser to present successive character apertures in the beam at each pulse. The drive system has a pre-stored drive profile for each possible angular increment to ensure that mask is very rapidly indexed between characters. Also disclosed is an optical transformation scheme for optionally transforming the mask characters to reduce the mask size, and a solid state spatial light modulator for obviating the need for a rotatable mask.

    Abstract: A method for stretching an assembly, e.g. a sliver or roving, of untwisted staple fibres (12) to reduce their diameter and increase their length employs false twist to provide grip between the fibres to ensure that stretching of the fibres and not drafting of the assembly occurs. The fibres are first plasticized by treatment with a suitable agent in a bath (16) and then passed through apparatus which employs a number of rotatable arrays (24, 25, 29, 32) of driven pulleys (26, 33). The arrays are mounted for rotation between two twist blocking nips (18, 18') and are rotatable about a longitudinal axis corresponding to the direction of travel of the assembly through the apparatus to impart false twist into the assembly. The assembly is stretched between two of the pulley arrays (24 and 25), the pulleys of the downstream array (25) being driven at a higher speed than the pulleys of the upstream array (24). The stretch is then set by steam heating in chamber (17) while the false twist is maintained by further rotatable pulley arrays (29). Post treatment stages (14, 46) may be added to further stabilize the stretched fibres. The fibres are animal hairs, for example wool.

    Abstract: A pump has a signal processor, including one forming part of a printed circuit board assembly, that receives signaling containing information about a voltage supplied to a motor to run a particular pump model, and also containing information about whether a current draw of the pump is lower than a predetermined low current level or is higher than a predetermined high current level; and determines whether to shut off the pump after a predetermined time, based on the signaling received. The signal processor provides control signalling to shut off the pump after the predetermined time if the current draw of the pump is lower than the predetermined low current level or is higher than the predetermined high current level, where the predetermined low current level and the predetermined high current level depend on the voltage being supplied to the motor to run the particular pump model.
