Abstract: Abstract of the Disclosure A ventilation system for removing fumes in the space above a cooking surface includes a hood located above the cooking surface which forms an entrainment chamber between the hood and the cooking surface, an air intake means having a blower which introduces outside air into the entrainment chamber and exhaust means in operative relation with the hood and including a filter member through which the air and the cooking fumes are passed to filter out the grease and to exhaust the filtered air and gasses into the atmosphere. The improvement is in the provision of an intake blower and an exhaust blower and additionally, an air spreading and dif-fusion means for forming an air pattern in the entrainment chamber corresponding to the planar area of the cooking sur-face.  The diffused inlet gasses thus mix with the heated fumes and gasses from the cooking surface and therefore elim-inates the need to pretemper the air entering the entrainment chamber.  The provision of the air spreading and diffusion means in the top of the hood eliminates double walled hood construction with the pretempering chamber and can eliminate energy requirements by as much as 80%.

Granted: 1981-03-03
Abstract: Abstract:     A container end for use in a container for pressurized liquid includes a push-in easy opening pouring closure defined by a weakening line.  There is also a smaller pressure releasing closure defined by a weakening line and capable of being opened by a push-in force.  The pressure releasing closure is formed partly within the pouring closure and partly outside the pouring closure.  The pressure releasing closure is so arranged as to be permanently opened when the pouring closure is opened to create an air venting passageway.  Both the closures are integrally connected to the container end at a position adjacent the periphery of the end whereby the permanently opened pressure releasing closure creates a liquid draining opening that facilitates substantially complete draining of the contents of the container.

Abstract: ABSTRACT OF THE DISCLOSURE:    A controlled protein fractionation method in which a cold protein-containing solution is circulated in contact with one side of a membrane and the temperature is controlled by circu-lating a protein precipitant solution in contact with the oppo-site side of the membrane.  The flow rate is increased and back pressure is exerted on the precipitant solution to cause it to penetrate the membrane, mix with the protein solution and pre-cipitate protein in fine particles along an inside membrane wall.  The precipitated protein may be concentrated and separated by centrifugation or diafiltration.  The membrane is preferably in the form of a plurality of hollow fibers.  Control of process variables increases yield and purity, decreases processing time and reduces degree of denaturization.  The method is especially applicable to carrying out the Cohn cold alcohol fractionation process.
