Title: Process for printing textile material.
IPC: D06P5/12
Filed: 1983-09-22
Abstract: By using water-repellent emulsions based on paraffin and/or polyorganosiloxanes in the preprinted resist it is possible to effect the preparation of white and coloured discharge resist effects on differently coloured grounds on synthetic fibre textile sheet materials with alkali-dischargeable disperse dyes by the energy-saving wet-on-wet technique. The novel process can also be used with advantage on polyester and cellulose or wool blend fabrics, in which case the diversity of design options can be increased still further by including reactive dyes. In addition, the crispness of the prints is significantly improved when, after the resists have been applied, the water-repellent emulsion is destroyed by adding sulphates or phosphates to the overprinting colour applied in the second phase.

Title: Controlling leaks between primary and secondary circuits of a steam generator of a pressurised water reactor system.
IPC: F22B37/42
Filed: 1984-12-18
Abstract: To control leaks between primary and secondary circuits of a steam generator (52) of a pressurised water reactor system, pressure equalisation is brought about by shutting off a live steam line (78) and feedwater line (74) connected to the secondary circuit of the steam generator (52) and by increasing the pressure in the resulting isolated secondary circuit by the injection of steam. For a U-type steam generator (52) in which there is a secondary steam space (72) between the top of the tubes (54) and the top of the steam generator, the secondary liquid level (82) is maintained above the top of the tubes (54) and the steam is injected (86) into the secondary steam space (72) to prevent contact of the steam with the tube walls and the resulting condensation of steam that would thus occur.

Title: Improved method and apparatus for incrementally stretching a zero strain stretch laminate web to impart elasticity thereto
Inventor: WEBER GERALD MARTIN
IPC: B29C55/18
Filed: 1992-02-27
Abstract: An improved method and apparatus for incrementally stretching "zero strain" stretch laminate webs to impart elasticity thereto in the direction of initial stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate material is formed of at least two plies of material which are either intermittently or substantially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condition. One of the plies is stretchable and elastomeric, while the second ply is elongatable, but not necessarily elastomeric. The second ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration. This results in z-direction bulking of the laminate web when the applied tension is released as well as subsequent elastic extensibility in the direction of initial stretching, at least up to the point of initial stretching. In a particularly preferred embodiment of the present invention the opposed peripheral edge portions of the laminate web to be incrementally stretched are subjected to restraint to substantially prevent inwardly directed slippage or contraction thereof in a direction parallel to the direction of stretching. This maximizes the effectiveness of the incremental web stretching operation by forcing the "zero strain" stretch laminate web to undergo the fullest possible degree of elongation during the incremental stretching operation.
