International Classification:

G01N 21/00

US Classification:

422 8205

Abstract:

A portable multi-channel device for optically testing of a liquid sample includes a controller; and a sample holder with a cylindrical sample compartment and at least two optical channels respectively for measuring turbidity of the sample liquid and for measuring one other optical property of the sample liquid. Each of the optical channels including: a light source placed at one end of the channel, a main detector placed across the sample compartment from the light source, a reference detector for measuring an intensity of light emitted by the light source, and an excitation focusing optic for directing a light emitted by the light source through the sample compartment towards the main detector. Signals from the reference detector of the channel, the main detector of the channel, and another main detector of another channel perpendicular to the channel are processed by the controller to evaluate the turbidity of the liquid sample.

Inventors:

Christopher B. Buck - Richmond VA

Assignee:

Libla Industries - Poplar Bluff MO

International Classification:

B27M 108

US Classification:

29430, 221168

Abstract:

An apparatus for making pallets includes an automatic stringer feeding system; an automatic stringer advancing system; a pallet assembly station; a nail delivery system; and a pallet stacking system. Wood stringers are automatically fed to a series of hoppers which facilitate advancing the stringers into the pallet assembly station. Spaced apart deck boards are nailed, via a gantry movable along a longitudinally extending frame on generally parallel spaced apart linear guide bearings, to both sides of the supporting base of transversely positioned stringers in the pallet assembly station. Multiple nailing stations in adjacent spaced relationship include a pneumatically driven double ram for nailing together stringers and overlying deck boards positioned within the pallet assembly station. The hopper loading system includes a first conveying system for conveying a layer of stringers from a stacked array in adjacent substantially horizontal relation along a first direction, and a second conveying system for conveying stringers in adjacent substantially horizontal relation to each hopper along a second direction substantially transverse to the first direction. A rare earth magnetic chuck is provided for holding a nail in position for nailing by the pneumatically driven ram.

G16H 40/20

Abstract:

A system and associated processes monitor hand hygiene compliance. The system includes hand hygiene product dispensers positioned within areas of concern (AOC) in a facility in which hand hygiene events are to be monitored. The dispensers detect dispense events initiated at the dispenser and transmit a dispense event signal indicative that a dispense event occurred along with dispenser identification information. The system also includes a plurality of compliance badges, each worn by a different person in the facility. The dispense event information may then be transferred to a local or remote computer for analysis and reporting on hand hygiene events taking place within the facility.

Abstract:

A controlling and monitoring control application associated with one or more work operations of one or more utility devices is disclosed. The controller is programmed for controlling one or more external work operations associated with one or more utility devices. An I/O board is connected in communication with the primary controller having a module with a plurality of device-specific control applications associated with one or more device-specific work operations. The housing of the controller includes one or more cable access points for plugging a cable into the controller. The cable access points are sealed to prevent water from entering into the housing. A mounting bracket assembly provides flexibility for mounting the controller at various orientations and/or positions. The controller also includes a DC control circuit for controlling backlight luminance over the entire dimming ratio.
