Abstract
A fluid manifold comprised of a manifold adapted to deliver fluid directly into a gap formed between a surface of a substrate and an acoustic transducer. The fluid is delivered into the gap at a variable rate along a length of the manifold. Preferably, the manifold includes a plurality of apertures positioned along the length of the manifold for dispensing the fluid into the gap at the variable rate.
Claims9
An apparatus comprising:
- a manifold configured for placement adjacent to an acoustic transducer;
- an angled face extending along a length of the manifold, with the angled face being oriented to deliver a fluid directly into a gap formed between a surface of a circular substrate and the acoustic transducer when the manifold has been placed adjacent to the acoustic transducer and the acoustic transducer is positioned adjacent to the circular substrate;
- and
- at least a first aperture and a second aperture positioned in the angled face for dispensing the fluid into the gap, with the first aperture dispensing the fluid at a different rate than the second aperture, whereby a variable amount of the fluid can be delivered into the gap along at least part of the length of the manifold through the first and second apertures.

An apparatus comprising:
- a manifold configured for placement adjacent to an acoustic transducer, with the manifold having an angled face that extends along a length of the manifold and faces in the direction of the acoustic transducer, and with the angled face of the manifold extending parallel to a radius of a circular substrate when the manifold is positioned over the circular substrate;
- and
- a plurality of apertures positioned in the angled face for dispensing a fluid directly into a gap formed between the surface of a circular substrate and the acoustic transducer, the plurality of apertures including at least a first aperture and a second aperture positioned along the length of the manifold for dispensing the fluid into the gap, with the first aperture dispensing the fluid at a different rate than the second aperture, whereby a variable amount of the fluid can be delivered into the gap along at least some of the length of the manifold.
