摘要:
A carrier supporting multiple filters is inserted jointly with the filters into an air sampler. The carrier includes an indexing structure to ensure correct positioning within the air sampler. A memory device physically associated with the carrier stores sample collection data provided by the air sampler. The stored data can be read by a read/write station at a lab, and transmitted to a processor. The processor also receives a weight reading from a communicating balance for each collected sample, and calculates therefrom mass concentration for each sample.

Exemplary embodiments of foam pumps, refill units and dispenser systems are disclosed herein. Some embodiments have a foam pump that includes a chamber having a liquid inlet, a vacuum outlet, a pressurized air inlet and a liquid air mixture outlet. An exemplary foam pump includes a liquid inlet valve to allow liquid to enter the chamber and to prevent liquid from exiting the chamber through the liquid inlet. Vacuum pressure applied to the vacuum outlet causes fluid to flow through the liquid inlet, past the liquid inlet valve and into the chamber. Pressurized air flows through the pressurized air inlet and mixes with the liquid and the liquid air mixture is forced out of the liquid air mixture outlet. The foam pump includes a mix media. The liquid air mixture flows through the mix media and flows through an outlet to be dispensed as a foam.

An exemplary foam dispenser includes a housing, a plate located in the housing, a first dispensing wheel located proximate the plate. The first dispensing wheel has a plurality of pinch members and is rotatable about an axis. The exemplary dispenser includes a second dispensing wheel located proximate the plate. The second dispensing wheel having a plurality of pinch members and rotatable about the same axis as the first dispensing wheel. Rotation of the first dispensing wheel is configured to pinch a first flexible tube against the plate and to move a first liquid through the first tube; and rotation of the second dispensing wheel is configured to pinch a second flexible tube against the plate and to move a second liquid through the first tube. The exemplary dispenser includes a motor for rotating the first and second dispensing wheels and a motor controller for starting and stopping the motor.

A modular bingo system (A) includes a separate primary console (10) and ball console (20). The ball console (20) includes: a bingo ball chamber (22) into which a plurality of numbered bingo balls are loaded and from which the bingo balls are dispensed in an unpredictable order; a ball tray (26) into which the operator places dispensed bingo balls; a first switch matrix (70) that identifies where bingo balls have been placed in the first ball tray (26); and, a ball console computer (40) that monitors the first switch matrix (70) and transmits data regarding its state. The primary console (10) receives the data regarding the state of the first switch matrix (70) from the first ball console (20) and includes: a main computer (13) programmed to conduct bingo games; a local display (12) operatively connected to the main computer (13); an adjustable arm (11) upon which the local display (12) is supported, the adjustable arm (11) providing a plurality of degrees of freedom of movement for adjusting the position of the local display (12); an UPS (80) that provides power to the first console (10); and, a data router (30) operatively connected to the main computer (13), the data router (30) providing communications links for the exchange of data between the main computer (13), the ball console computer (40) and an external flashboard (50).
摘要:
A packaging and disposal system for sealing waste and related materials within flexible plastic tubing for odorless and sanitary disposal. Improvements in the latch, including the addition of a transverse mounted latch spring, and improvements in the support retention springs serve to increase the ability of the device to operate efficiently and effectively and reduce the potential of accidental spills or other exposure of the waste package. The latch requires two independent motions to actuate and incorporates a transversely mounted latch spring. The reduced cross-sectional area of the retention spring design concentrates force applied to the package to increase the effective holding ability of the system.
摘要:
An encapsulated ballistic protection system (EBPS). In one embodiment, an EBPS for protecting a human or an object from a projectile includes one or more ballistic protection material layers at least substantially encapsulated by encapsulation material having a tensile strength of 20,000 psi or greater. Additionally, in one embodiment, an EBPS includes one or more ballistic protection material layers that are substantially encapsulated by the encapsulation material on a first side adapted to face the human or the object and on a second side opposite the first side and adapted to face the projectile, and the EBPS further includes a compressible layer between the one or more ballistic protection material layers and the encapsulation material on the first side, the compressible layer configured to at least one of dissipate energy, reduce velocity of the projectile, and reduce backface deformation.
