Abstract:
An airbrush having a nozzle (22) through which gas can flow, the end of the nozzle having an inclined surface (30). The apparatus also includes support means for a liquid source (28) which, in use, is directed towards the inclined surface of the nozzle.
Abstract:
A spring (4) comprising two branches (41, 42) is connected by a bend (40) such that the branches form, in the idle position, an acute angle. Said branches are elastically mobile in relation to each other by relative pivoting around the bend until they come into contact with each other so as to be extended relatively in parallel. The spring also comprises a spring stiffness variation systems (43, 44) which produce different stiffnesses depending on whether the spring is compressed or slackened. Said variation system producing a low stiffness when the branches are extended relatively in parallel and a greater stiffness when the branches are forced together from the idle position.
Abstract:
Liquid dispensing apparatus comprises a tubular casing having at one of its ends a mouthpiece and an elongate cap, and at the other of its ends a nozzle having an orifice in communication with an expansion chamber bounded by sides which diverge away from the orifice. A liquid source including an elongate body and an absorbent nib (e.g. a felt-tipped pen) is located within the casing with side surfaces of the pen body spaced from internal was surfaces of the casing to define an air flow passageway therebetween. First and second stop means are provided within the casing against the first of which a surface of the elongate body can abut to position the nib of the liquid source within or in close proximity to the nozzle orifice, and against the second of which a rearward end of the elongate body can abut to position the nib of the liquid source in a relatively airtight manner into one end of the elongate cap. The other end of the elongate cap is closed. Thus the liquid source can selectively be positioned with its nib within or in close proximity to the casing nozzle or with its nib effectively sealed within the elongate cap when the apparatus is not in use.
Abstract:
Apparatus for dispensing a fine spray of liquid particles comprises a hollow tubular casing (1) whose internal cross section is formed with at least one abutment surface. A tubular liquid source (2) is positioned within the casing (1) with the abutment surface in close contact with the outer surface of the source to provide support thereto. The casing (1) includes a passageway for the flow of air from a mouthpiece (3) positioned at one end of the casing (1) to a nozzle (9) positioned at the other end of the casing (1) into which the discharge end of the liquid source protrudes. The liquid source may comprise a pen formed with a nib (14) of absorbent material.
