Title: An ecological restoration structure for grassland opencast mine berms
Inventor: DE LIGEER
IPC: E02D17/20
Filed: 2023-04-28
Granted: 2023-11-07
Abstract: The invention discloses an ecological restoration structure for grassland opencast mine berms, comprising a protective slope, a protective plate fixedly connected to the surface of one side of said protective slope, the top of said protective plate penetrating and provided with evenly distributed recesses, and a transition plate fixedly connected to the bottom of said protective slope. said protective slope has a transition plate fixedly connected to the bottom of said protective slope. In the present invention, the soil in the grooves is watered through the sprinkler pipe and eventually through the sprinkler head. When it rains, the rainwater enters the collection chamber and follows the overflow channel into the storage box, thus making effective use of water resources and avoiding the problem of low survival rate of vegetation due to the weak water absorption of the soil on the slope of the mine.

Inventor: PRITCHARD JOHN NIGEL
IPC: A61M15/00
Filed: 1993-03-30
Abstract: A dry powder inhaler (10) consists of a chamber (12) into which powder is introduced from a metering system, and a mouthpiece (26) through which a patient inhales, connected by a duct (16), so that air flows through the chamber carrying the powder into the patient's lungs. Within the duct is an impactor (25) consisting of a plate (27) spaced in front of a similarly sized aperture, and between the chamber and the impactor plate is an orifice (18) narrower than the duct, so the air stream is diverted along S-shaped paths to avoid the plate. The presence of the impactor can improve the efficiency of delivery of a drug to the lungs, and decrease the unwanted dose to the mouth and throat, as the latter is principally due to agglomerates or larger particles which are intercepted or broken up by the impactor.

Abstract: A method of making a gas permeable material having a diffusive gas permeability at 0.21 atmosphere diffusive driving force in the range of about 0.5x105 cm3/100 square inches/day to about 2x105 cm3/100 square inches/day. The method comprises the step of coating a pattern of spots of a gas impermeable material onto a porous substrate, followed by a step of enlarging the pattern of spots to cover greater than about 95% of the porous substrate such that the gas permeability occurs only through openings between the pattern of spots. The gas impermeable material is preferably a hot melt adhesive and the porous substrate is preferably a nonwoven. The step of enlarging the pattern of spots includes smearing substantially circular spots into oblong spots as the pattern of spots is printed onto the porous substrate until the oblong spots partially overlap. The smearing is achieved by operating a printing screen at a surface speed higher than a draw rate of the porous substrate. Alternatively, the step of enlarging the pattern of spots includes calendering through a fixed gap the porous substrate after the pattern of spots is coated thereon.
