International Classification:

A61M 1500

US Classification:

12820315, 12820321

Abstract:

The invention provides various apparatus and methods for aerosolizing a powdered medicament. In one exemplary embodiment, an apparatus includes a pressurization cylinder, and a piston which is slidable within the cylinder to pressurize a gas. A handle is coupled to the piston and is movable between an extended position and a home position to pressurize the gas. An aerosolizing mechanism is included and is configured to aerosolize a powdered medicament that is held within a receptacle with pressurized gas from the cylinder. A carriage assembly is included to receive the receptacle and to couple the receptacle to the aerosolizing mechanism. A first and a second interlock are operably engageable with the carriage assembly to prevent coupling of the receptacle with the aerosolization mechanism. The first interlock is released to allow movement of the carriage upon movement of the handle to the extended position. The second interlock remains engaged if the receptacle is only partially inserted into the carriage assembly.

US Classification:

360 67, 360 46, 360 61, 360 75

Abstract:

A disk drive includes recording media having one or more recording surfaces, one or more transducer heads positionable relative to the recording surfaces by an actuator operating within a head position servo loop, and a data transfer driver. A preamplifier in the data transfer driver includes one or more head interfaces, each head interface for controlling a transducer head for read and write operations, and a mode controller for controlling each head interface based on configuration information for selectively (i) reading data from at least one recording surface, (ii) writing data to at least one recording surface, and (iii) simultaneously reading data (such as a reference pattern) from at least one recording surface and writing data (such as servo patterns) to at least one recording surface.

International Classification:

US Classification:

47 327

Abstract:

Structural cells that are placed beneath hardscape. The cells are strong enough to structurally support the hardscape, effectively bearing its weight along with the weight of any load it carries. Furthermore, even though the cells are strong enough to offer structural support of a hardscape, the cells are also designed to be relatively lightweight, stackable, and open, allowing approximately 90% of their volume, or more, to be free volume that can contain uncompacted soil, tree roots, and the like. The cells achieve these attributes through a design that includes a flexible bottom frame, and support members. These support members have a cross-sectional shape that allows for axial rigidity while also preventing any interlocking between support members when cells are stacked. In one embodiment, this cross-sectional shape is a generally quadrifoil shape.

Appl. No.:

5/959515

Inventors:

Fred J. Szekely - Tujunga CA
Charles A. Ray - Arcadia CA

Assignee:

Clemar Manufacturing Corp. - Azusa CA

International Classification:

G05D 1616
F16K 31365

US Classification:

137269

Abstract:

For use with a remotely actuated fluid supply valve, an internally balanced pressure regulating module is provided for regulating the pressure downstream of the valve by modulating the rate at which fluid is bled from a closure chamber of the valve in response to downstream pressure. The module includes a flow restricting member arranged at the open end of a cylinder and having a first surface facing the open end of the cylinder and a second surface facing outwardly of the cylinder and exposed to downstream pressure. The flow restricting member is secured to a piston in the cylinder which is resiliently biased toward the open end of the cylinder, and the downstream pressure acting on the second surface urges the first surface against the force of the biasing means, into a flow restricting relationship with the open end of the cylinder.

International Classification:

B05B 1506

US Classification:

239201

Abstract:

An improved locking assembly is provided for releasably locking a valve unit incorporated into a sprinkler housing or the like, wherein the locking assembly prevents the valve unit from being driven from the housing as a projectile by water under pressure at the upstream side of the valve unit. The valve unit includes a mounting ring normally held seated upon a shoulder seat within the base of the sprikler housing by the locking assembly including a stacked pair of snap rings installed into an enlarged housing lock groove thereby positioning a movable valve member in association with a valve seat to control water flow into the sprinkler housing. The valve unit is removable from the housing, for example, for maintenance purposes by removing the two snap rings one at a time. In the event the first snap ring is removed without prior relieving of water pressure at the upstream side of the valve unit, the water pressure lifts the valve unit from the valve seat to permit water flow into the housing while the second snap ring remains locked within the lock groove to block valve unit removal. When the water flow is turned off, the valve unit is removable quickly and easily by removal of the second snap ring.
