摘要:
A showerhead adapted to automatically control the discharge pressure of shower water according to variations in water pressure and make the troublesome faucet operation unnecessary, thus ensuring a comfortable shower bathing. The showerhead (1) causes water that is being fed from a water supply through a predetermined piping to be discharged outside through discharge holes (H) in a shower nozzle (5). The shower nozzle (5) is made of a water-resistant expansion material, such as silicone rubber, and provided in its expansion surface with discharge holes (H) that can be enlarged and reduced according to variations in the water pressure in the showerhead (1).

摘要:
A shower head (40) having a plurality of nozzles (50) capable of attachment to a flexible shower arm (64). The shower head (40) has a unique nozzle construction that allows for the manipulation of an external flexible nozzle to remove mineral deposits and has an internal, rigid nozzle structure for efficiently forming an aesthetically pleasing water stream. The shower head (40) may have two available flow configurations which are selectable by a valve.

A hand holdable spray delivery system (10) for dispensing a relatively viscous and/or solids laden liquid is provided. This spray delivery system (10) includes a container (30) adapted to house the liquid. A manually actuated pump device (20) is mounted on the container (30). The pump device (20) including an inlet passage (23), a pump chamber (28), and a discharge passage (27) having a distal end connected in liquid communication so that the liquid is pumped from within the container (30), through the inlet passage (23), into the pump chamber (28) and through the discharge passage (27) upon manual actuation of the pump device (20). A slotted spray nozzle (40) including a housing (55) having an inlet side (46) and an exit side (44) is also included. The housing (55) having an internal recess (45) through the inlet side (46) that terminates in an elongated orifice (42) at the exit side (48). The internal recess (45) being attached in liquid communication to the distal end of the discharge passage (27) such that the liquid passing through the discharge passage (27) flows through the slotted spray nozzle (40) and converges toward the elongated orifice (42). The liquid is dispensed therefrom in a dispersed spray. The slotted spray nozzle (40) can be made of a rigid material or an elastomeric material. A fan shaped dispersed spray pattern is generated when the nozzle (40) is made using a rigid material, however, when an elastomeric material is utilized, the nozzle (40) is capable of ejecting particles larger than the smallest dimension of the elongated orifice (42), thereby substantially reducing the likelihood of clogging. Several versions of the spray delivery system (10) are illustrated, including a trigger operated sprayer and a reciprocating finger pump (20).
摘要:
The invention concerns an elastic hose with a shaped unsymmetrical cross-section for the delivery of liquids or gases through apertures along the hose, the delivery rate being uniform even over long lengths of hose. The hose is optionally housed in an outer tension-proof cover tube with an open cross-section, in particular a tube open along a generatrix, for the reception of additioned liquids or gases.

摘要:
Mikrodosiervorrichtung und Verfahren zur dosierten Abgabe von Flüssigkeiten Zusammenfassung Eine Mikrodosiervorrichtung umfasst eine Fluidleitung (100), die einen flexiblen Schlauch aufweist, mit einem ersten Ende (102) zum Verbinden mit einem Flüssigkeitsreservoir und einem zweiten Ende (104), an dem sich eine Auslassöffnung befindet. Eine Betätigungseinrichtung mit einem Verdränger (108) mit einstellbarem Hub ist vorgesehen, durch den das Volumen eines Abschnitts des flexiblen Schlauchs veränderbar ist, um dadurch durch Bewegen des Verdrängers (108) zwischen einer ersten Endstellung und einer zweiten Endstellung Flüssigkeit (130) als freifliegende Tröpfchen oder als freifliegender Strahl an der Auslassöffnung abzugeben, wobei der Schlauch in der ersten oder der zweiten Endstellung teilweise zusammengedrückt ist. Anders ausgedrückt umfasst eine Mikrodosiervorrichtung eine Fluidleitung (100), die einen Abschnitt aufweist, entlang dem ein Querschnitt der Fluidleitung durch eine Betätigungseinrichtung veränderbar ist, um eine Änderung des Volumens der Fluidleitung zu bewirken. Ein Verhältnis einer fluidischen Impedanz zwischen der Position der Betätigungseinrichtung und der Auslassöffnung zu einer fluidischen Impedanz zwischen einem ersten Ende der Fluidleitung und der Position der Betätigungseinrichtung ist durch Ändern der Position der Betätigungseinrichtung variierbar, so dass ein an der Auslassöffnung abgegebenes Dosiervolumen dadurch um zumindest 10% variierbar ist.
摘要:
Methods of generating pores (70) in thin sheets (20, 30) of material, typically thin polymer films (20, 30), are provided. The methods allow for generation of pores (70) which uniformly penetrate the material. The method comprises laminating a thick film (20) onto a thin film (30), then directing a laser source onto the thin film (30) so as to form pores (70) through the thin film (30). The increased stiffness conferred by the thick film (20) reduces wrinkle formation in the thin film (30), resulting in uniform thickness of the thin film (30) and consequent uniformity of pore depth. The invention further provides aerosolization containers (10) and devices comprising membranes (40) formed according to the invention.
