Abstract: Description is made of an increased volume synthetic fibre consisting of a porous central core and a large number of short porous lateral threads integral with the core and distributed along the whole length of the fibre so as to form a voluminous branching structure. There is also a description of the procedure used to produce the fibre, which consists of the mixing of a synthetic polymer with an inflating agent which expands when heated, the spinning by means of melting the mixture which results in the inflation and fringing of the threads produced, caused by the inflating agent, followed by the drawing and fixing of the threads thus produced while they are still hot. Examples of the use of the fibres in question are given by filters and padding.

Abstract: PCT No. PCT/GB88/00968 Sec. 371 Date May 1, 1990 Sec. 102(e) Date May 1, 1990 PCT Filed Nov. 9, 1988 PCT Pub. No. WO89/04392 PCT Pub. Date May 18, 1989.The invention provides a method and apparatus for energy efficient drying of moist material, for example washed garments, using superheated steam as the drying medium. Apparatus for carrying out the method comprises a casing 10 which is thermally insulated and gas-tight apart from an outlet vent 11. The air initially within the casing is circulated by a fan 13 through a heat source 16 and through moist garments 17. The heated air produces steam from the moisture in the garments which, due to the resultant increase in pressure in the casing, eventually displaces the air from the casing. Continued recirculation of the steam through the heat source 16 causes it to become superheated. As the process continues, and more moisture is evaporated from the garments, a portion of the superheated steam is continually discharged through the vent 11 where it passes into a condenser where its thermal energy is recovered and is transferred by heat exchange to, for example, water which may be used for other purposes.

Abstract: An elevator control apparatus suppresses the jerk at the start-up of speed controlled elevator installations in both directions of travel, not only the friction jerk at the transition from the static friction to the sliding friction, but also the imbalance jerk at unbalanced car loads. A set point signal multiplier is connected to the output side of a set point memory in the hoist motor drive control and the set point multiplying factor can be controlled by way of an on/off circuit. The multiplier is switched, prior to the start of the movement, by the on/off circuit to a value greater than one, and is switched back to one at start of movement in the direction of travel. The motor driving force is controlled to a value which, when summed with the imbalance force, is equal to the sliding friction force at start-up. This suppression of jerks is eminently suitable for the refitting of controlled elevator drives and increases, due to the earlier start of movement, their elevating capacity.

Abstract: The vehicle fuel regulation control (14) uses 2 parallel control stages (10.1.1; 10.2.1), each of which determines the required fuel setting for the fuel injection pump in dependance on a signal from a respective sensor device (11.1, 11.2). The fuel setting value from one control stage (10.1.1) is fed to the fuel injection pump (12.1) for corresponding adjustment and to a calibration stage (15) for comparison with the calculated fuel setting value provided by the second control stage (10.2.1). The output of the calibration stage (15) is used for precise adjustment of the first control stage (10.1.1). The first control stage (10.1.1) has a lower accuracy but a higher response rate and the second control stage (10.2.1) has a higher precision but a relatively low response rate, the calibration stage (15) having a delay which corresponds to the latter.
