Abstract: A wastewater solid and/or liquid specimen/sample collection system provides continuous time sampling of a liquid source. The system includes an enclosure whose temperature is maintained within a temperature range for sample collection and storage. A sample collection container within the enclosure has an inlet for receiving intake liquid flow containing the sample being collected. An intake liquid conduit in fluid connection with the enclosure/container has a second end submerged into the liquid source. A pump provides an inlet connector in fluid connection with the intake liquid conduit. A controller communicatively coupled to an electrical motor of the pump transmits a pump activation signal with pump speed and length of time for sample collection, which activates the pump to initiate suction at the inlet connector. The pump suctions intake liquid at a flow rate that allows continuous sampling of the liquid source over an entirety of the length of sampling time.

Abstract: A portable, personal protective (PPP) respirator includes a protective barrier made of pliable material that expands when air flow is provided to create a volumetric interior air space, the barrier being non-porous and configured with an opening at one end and sealed at all other surfaces. The PPP respirator includes a barrier collar that is bendable to conform to being worn over a neck and shoulders of a person, the barrier collar providing an attachment component around which material from the open end of the barrier is wrapped to hold the protective barrier in place when the barrier collar is worn around the neck of the person. The PPP respirator includes a mantle having a neck opening for placing of the mantle over the person's head, the mantle resting on the person's neck and shoulders and upper torso when worn. The protective barrier prevents direct exposure to an exterior environment.

Abstract: A method and apparatus controls the sampling of a fluid flow related event by: receiving a selection of one or more situational parameters and a selection of a calculation basis parameter and value; performing a computation that calculates and outputs a result containing a listing of parameters and two sets of associated parameter values corresponding to a flow trigger, based on the selected calculation basis parameter and the selected situational parameters. The parameter values include both a precise computational result and a situation-specific best fit result. The method includes triggering a sampling mechanism to initiate collection of samples of the fluid flow based on the best fit result. The computation of the result comprises: executing a fluid flow trigger calculation program that computes the flow trigger based on an analysis of both the situational parameters with associated situational parameter values and the selected calculation basis parameter.

Abstract: An insulating wrap for adding to containers to prevent heat adsorbsion or heat loss is composed of conductive insulation material as well as radian barrier material. The insulating wrap conforms to the container shape and has multiple attachment elements for closing and retaining the insulating wrap to the container. The insulating wrap may also have attachment elements for adding a top and/or a bottom insulating cover also comprising conductive insulation material as well as radian barrier material. The insulating wrap may employ insulating tape on the top and bottom edges to protect the edges as well as to further improve heat transfer at the interface between the top or bottom covers and the insulating wrap. In one embodiment the top cover may have an integrated handle piece where the top and bottom cover attachments have sufficient strength to allow a container to be lifted. This embodiment facilitates lifting of a insulated container.

Abstract: A system for storing and dispensing liquid materials includes a container base, a removable closure for loading the container unit, and a spout valve on the closure and/or on the container body. The container unit provides a sealable large opening that allows the liquid material to be easily loaded into the container unit for storage. The closure seals and is easily removed facilitating cleaning of the container unit. The spout valve on the closure allows controlled dispensing of the stored liquid material. An insulation system is provide to adapt the system for thermally sensitive liquid materials. Additionally a brace unit supports the container unit in a desired dispensing angle to maximize the rate of liquid material removal and prevent the container unit from moving during dispensing.
