Abstract: A low shrinkage, dimensionally stable, polyester industrial fiber is produced by a process which involves conditions of continuously spinning and drawing filaments wherein the filaments are passed through a steam impinging draw point localizing jet (25) at a temperature of about 460°C. to 580°C. to thereby heat the filaments substantially immediately above their second order transition temperature. The low shrinkage polyester fibers are particularly useful in the preparation of industrial products, including industrial belts, conveyor belts, and reinforced elastomeric structures.

Abstract: Pressure equalisers of this type have at least one lock bunker (3 or 4) which is located upstream of the furnace chamber in the charging direction and which is associated with a charge material inlet valve (7 or 8) providing a seal against the atmosphere and a charge material outlet valve (11 or 12) providing a seal against the furnace chamber, and a gas pipe (13) connected to the lock bunker (3 or 4) can be connected alternately to pure gas supply and to discharge into the atmosphere. Large blast furnaces pose problems with respect to emissions of dust, gas and sound, which are now subject to statutory prescribed values. In order to avoid heat-insulating packing of the housings, which is disadvantageous for heat removal, it is proposed that, in addition to the lock bunker (3), at least one further gas space container, for example another lock bunker (4), which has at least one isolation valve (19 or 20), is provided and that the lock bunker (3) and the gas space container are mutually connected by pressure-equalising pipes (18) which can operate in either direction. This results in lower gas velocities and less troublesome noise when the pressurised gases are discharged into the atmosphere. <IMAGE>

Abstract: Turf maintenance machines have working units which are desirably counterbalanced at least partially in the working position to allow floating over ground contours. Known machines tend to have a relatively wide variation in the counterbalanced weight over the range of working levels. The invention provides a machine with a gas spring (67) which applies an almost constant force and is located to act so that the resultant weight of its associated unit is substantially constant at all working levels. Preferably this is achieved by having the inner end of a lifting and lowering arm (23) supporting a lateral unit (15) welded to a sleeve (39), freely rotatable on a shaft (27), which carries a pair of cranks (43, 47) to which the gas spring and an hydraulic lifting and lowering ram (51) are pivotally connected. The machine may have two lateral units (15, 17) on opposite sides and a central unit all counterbalanced by gas springs.
