Appl. No.:

6/282226

Inventors:

John C. Silva - Ipswich MA

International Classification:

F02M 3100
F02M 1304

US Classification:

123522

Abstract:

An evaporative carburetor has a normally pressure-tight chamber which houses an evaporator tray to which a fuel supply delivers gasoline. A first air passage in the carburetor chamber communicates from a first, automatically-valved, air inlet to pick up gasoline particles and vapor from the evaporator tray. A second air passage communicates from the evaporator tray to a mixing region and includes a particle arrester. A heater maintains the evaporator tray and the second passage above a selected temperature. A second, externally-controlled, valved inlet feeds air to the mixing region, and a third air passage communicates from the mixing region to a throttled output port. An aqueous control liquid is injected into the air stream in the third passage.

Inventors:

John C. Silva - Ipswich MA

International Classification:

B03C 314

US Classification:

96 50

Abstract:

An air ionization device for use in industrial, commercial or residential settings which includes a core section shaped to provide internal venturi action in order to force air outwardly from an ozone manifold. Air fins are provided at the front of the cabinet to prevent turbulence of air as it exits the cabinet. The device further includes electronics for providing controlled negative ozone and ionization output, and a 12 VDC power supply for operating system fans and relays. The device can operate as a master unit to control up to four slave units (i. e. up to five units on one system) for providing even distribution of ions and ozone over large industrial areas. In addition, various features are provided to allow for facile servicing of the device, including a purging hose mounted inside the core, removably replaceable ionization needles, and ozone relief holes positioned directly behind the ionization needles for constantly purging the needles and keeping them clean.

International Classification:

G06Q 10/06

Abstract:

When providing a smart phone based multi-patient worklist (SPWL), a smartphone application, or “app,” is provided for nurses or other healthcare providers to plan and coordinate the care of their assigned patients. The SPWL includes time-based and patient-based screens that allow a nurse to determine what needs to be done for a particular patient as well as what needs to be done at a particular time or time range for a group of patients. Navigation between different views, such as zooming in or out to different levels of detail granularity can be performed, e.g., via touchscreen or the like. Through the use of icons, the SPWL can provide optimizing information detail using limited screen space.
