摘要:
Apparatus for sterilizing a transfer conduit having(a) a source of steam connected to the transfer conduit,(b) a condensate conduit for draining steam condensate from the transfer conduit,(c) a valve in the condensate conduit having a valve body with an upstream portion and a downstream portion, the portions are separated by a rapidly opening flow control means, such as a diaphragm,(d) a temperature sensor in the upstream portion of the valve body, and(e) a temperature controller connected to the temperature sensor adapted to read the temperature in the upstream portion of the valve body and to open the valve when the temperature drops below a fixed set point and to close the valve when the temperature is above the fixed set point.A steam condensate drain control system and a steam condensate valve are also described and claimed.

An automated system is disclosed for managing accounts receivable for outstanding healthcare accounts. In particular, the system in accordance with the present invention is an automated system which preemptively assesses the risk of denials of outstanding healthcare accounts by way of a self-learning engine driven by current data and prioritizes those accounts for follow up according to the risk profile of the account. As such, the system is able to minimize denials by the respective payers thereby improving optimizing the efforts of healthcare accounts receivable personnel while improving the revenue yield and minimizing the revenue cycle.

A low cost valve and system for automated ebb and flow irrigation utilizes a collapsible sleeve to control fluid flow direction. No external power, moving parts, or floats are needed to operate the valve, resulting in improved reliability, low operating cost, and minimal need for maintenance. The valve operates using feed pressure to close the drain when hydroponic nutrient solution is pumped into the cultivation chamber. The valve drains automatically once the pump is stopped, usually by means of a timer, and the spent hydroponic solution is recovered. The fill/drain cycle is repeated as needed to keep the plants moist, yet not waterlogged.

This invention provides a system and apparatus that is able to authenticate and prevent illegal manufacturing and unauthorized operation of disposable bioprocess components. This invention utilizes a ferro-electric random access memory (FRAM) chip to store error-correctable information on a RFID tag attached to the disposable bioprocess components, where the error-correctable information is written into the memory chip, so that the information can remain in the chip when the RFID tag and disposable bioprocess component is gamma-sterilized. Also, this invention includes a method for authenticating the disposable bioprocess component that reduces liability in that a counterfeit poor quality disposable component is not used on the hardware so the user will not file an unjustified complaint.

Methods and systems for processing oilseed meal. Oilseed meal is hydrated to provide a hydrated oilseed meal. A particle size of the hydrated oilseed meal is reduced to provide a size-reduced oilseed meal. Enhanced oilseed meal is physically separated from the size-reduced oilseed meal.
摘要:
A method and apparatus is provided for non-invasively mixing ingredients in closed containers. Mixing is performed by inducing waves in the liquid to be mixed. This is achieved by rocking the container in precise phase so as to produce resonance. With the waves moving back and forth in resonance, it is possible to mix with very low energy requirements compared to prior art. Mixing ingredients with resonant waves in a closed container eliminates the need for an invasive mixer and has obvious advantages in minimizing contamination. This makes the device ideal for biological processing that typically require sterile operation.

A disposable bioreactor for perfusion cell culture. Cells are grown in a plastic bag that is rocked and aerated on a mechanical platform. The bioreactor bag contains a filter that allows liquid to be removed from the bioreactor-without losing cells. Nutrients may be added through another port. The perfusion filter is constructed such that it can move freely on the liquid surface. The filter is flicked rapidly across the surface as a result of the rocking motion of the bioreactor and this tangential motion of the filter keeps it from clogging. A weight-based control system regulates feed and harvest rates and allows weeks of continuous operation. This invention has numerous applications in biotechnology and medicine.

The present invention provides a novel apparatus for culturing animal, insect, microbial, or plant cells whereby an inflated plastic bag provides a sterile, disposable cultivation chamber. The inflated bag is partially filled with liquid cultivation media and cells, and placed on rocking mechanism that moves the bag to and fro thereby inducing a wave-like motion to the liquid contained therein. This motion ensures cell suspension, bulk mixing, and oxygen transfer from the liquid surface to the respiring cells without damaging shear forces or foam generation. Air is passed through the bag to provide oxygen, and sweep out evolved carbon dioxide.

The present invention provides synthetic processes for preparing racemic and/or optically pure epicatechin, epigallocatechin and related polyphenols as such or as their variously functionalized derivatives. A principle objective of the disclosure is to provide a new and useful method of synthesis to obtain polyphenols in isomerically pure and/or racemic forms.
