Abstract: Materials and methods to control a nutrient feed in a cell culture process is provided. A sample is received from a bioreactor comprising a cell culture. A viable cell density and a residual nutrient measurement are determined from the received sample. A daily nutrient feeding target is calculated based on the viable cell density and the residual nutrient measurement. The nutrient is fed to the bioreactor according to the calculated daily nutrient feeding target.

Abstract: A burner assembly system is disposed in a rear side, i.e. back side, of a deep fryer. The burner assembly system includes an aperture disposed in a side of a bottom portion at the rear of a fryer cabinet of the controlled deep fryer. A burner at the rear of the fryer cabinet is coupled to the aperture and is adapted to receive fuel that enters through the aperture. An ignition assembly is disposed within the burner and ignites the received fuel. A flue is disposed at the rear of and within the fryer cabinet and receives combustion gases and heat from the burner created by the ignition of fuel. A heat exchanger is disposed within the flue at the rear of the fryer cabinet and is heated by heat conveyed through the flue from the ignition of fuel in the burner.

Abstract: A serviceable pump includes a motor disposed at an end of the serviceable pump and connected to a gear portion with a pump shaft. The gear portion receives fluid from and outputs fluid to a system such as a deep fryer cooking system. The gear portion includes at least one channel for receiving fluid, such as oil, to lubricate the gears and a fluid discharge aperture to push fluid into a cooling loop at a first end of the cooling loop. The cooling loop cools the fluid passing through the serviceable pump and is disposed between the motor and the gear portion. The cooling loop is connected to a seal assembly that surrounds the pump input shaft at a second end of the loop. The seal assembly allows the cooled fluid to pass along the pump input shaft.

Abstract: A substantially closed loop filtration and convection system is configured to move fluid/oil volume within a fryer vat. The vat has a flow directed inlet, which directs flow of cooking fluid in a direction across the bottom of the vat directing the flow of oil and crumbs/debris across the vat, up and across a flow separation portion toward and into a cleaning zone portion of the vat. A crumb tray or crumb/debris catch system is disposed in the cleaning zone adjacent to the vat.

The multi-bank cooking system may include two or more rack-fryer systems, each with discrete frypots, operating mechanisms and cooking controllers. Each of the discrete cooking systems, may share a common plumbing system with integrated valves and controls receiving coordinated safety signals to facilitate safe and efficient operation of the system.

Abstract: A system for automating the removal of cooking racks or trays laden with food items. The automatic rack lifting system includes a fryer assembly having a frypot and a liftable traveler assembly with a removable rack carrier or cooking carriage that carries a plurality of removable cooking baskets for food into and out of the cooking medium or oil disposed within the frypot. The system may further include lift arms removably secured to an actuation support structure. The automatic rack lifting system comprises a lift system for automated (e.g. under software program control) or manually controlled automatic lifting of a cooking carriage.

Abstract: The present disclosure provides a filter tray and filter tray assembly with removable filter media. The filter tray may include a quick-release retainer or spring-clip pivotally engaged with the tray and engageable with the tray to form a pressure fit over a filter medium. The filter tray may further include or interface to a handle extension and/or a removeable handle for manipulation of the filter tray, including removing and replacing the filter tray in a deep fryer cooking system.

Abstract: An implantable device comprises a polymer structure having an outer surface facing a surrounding tissue when the implantable device is implanted in a subject body. At least a portion of the surface of the structure has a semi-random pattern of extending micropillars. The semi-random pattern of micropillars on the surface contributes to advantageous surface characteristics of the implantable device in terms of reducing adhesion viable cells to the implantable device as compared to regular patterns of micropillars.

Abstract: A design is disclosed for a catheter assembly used during interventional and/or diagnostic procedures. The catheter includes a plurality of openings that allow for controlled fluid flow as the fluid exits the lumen of the catheter and can be inserted into the vascular system over a guidewire. As a result, the openings balance the fluid forces and, thereby, stabilize the distal tip to accommodate a wide range of injection parameters. The particular design of the catheter assembly of the present invention also reduces and/or eliminates recoil of the catheter tip during high volume injections, such as those associated with coronary or ventricular angiography.

Abstract: The tool for enhancing visualization during surgery includes a shaft having a balloon member at a distal end. A fluid conduit through the shaft permits passing and inflation fluid into the balloon to selectively inflate the balloon. The balloon is formed of a material transparent to a wavelength of interest. A waveguide extends within the shaft into the interior of the balloon to visualize anatomical features external to the balloon.

Abstract: A fry cooker uses a flow of cooking oil or other medium during the cooking operation to strain out or screen particles that cause degradation of the cooking oil or medium. There are several configurations of the fryer that achieve this result. One is a fryer with a first coarse strainer and a second fine sieve or screen. The first screen is used to swiftly screen and separate coarse particles. The second is used as a finer filter to separate finer particles. Either screen may also be adapted to hold a packet for chemically treating and preserving the cooking medium. Another configuration may include a fryer basket that has a straining portion for removing particulates from the cooking medium. The basket may have an upper sealing portion and a lower straining portion.

Abstract: A catheter for use in introducing fluid into a vessel or other bodily structure. The catheter comprises a stem and a restrictor. The stem has approximate a distal end thereof a porous section that defines microholes distributed thereabout, which are inclined by a predetermined angle in the proximal direction. Affixed to the stem, the restrictor includes a conically-shaped valve with an apex thereof defining an opening and pointing in the proximal direction. The opening generally decreases in size as the conically-shaped valve flattens out distally as the pressure of the fluid within the tip increases. The forces of the fluid flowing out of the opening of the restrictor and out of the microholes of the stem substantially balance thereby substantially eliminating both recoil and whipping of the catheter, thus enabling its position to remain exceptionally stable while the fluid is finely dispersed therefrom in a cloud-like form.
