Abstract: METHOD OF INCREASING PRODUCT EXPRESSION        THROUGH SOLUTE STRESS               Abstract of the Disclosure A method of determining the optimal level of product expression and cell growth of animal cell cul-ture  is  described.   The  method generally comprises culturing cells under  conditions  of  solute  stress, that  is, under conditions whereby optimal cell growth is decreased yet levels of product expression are  in-creased.   In  a preferred embodiment of the invention is described a method of increasing the yield of mono-clonal antibodies comprising culturing hybridoma cells in an environment of solute stress.  One  approach  to the creation of such an environment is the addition of inorganic salts, organic polyols, or  metabolic  prod-ucts  to  the  culture  medium.  One to three fold in-creases in antibody yield have been obtained by  these methods.

Abstract: ABSTRACT       An implement is provided for opening envelopes in which a ram (28) is reciprocally mounted within a  hollow sleeve (14).  A transverse envelope receiving crevice or slot (22) is defined at one end of the sleeve (14) and the ram (28) carries a blade (32) which has a cutting edge (34) directed toward the envelope receiving slot.  A spring (38) acts between the sleeve and the ram to urge the cutting edge of the blade away from the transverse slot so that the blade is not exposed unless the spring bias is overcome. Alternatively, a blade (120) is disposed within a body (114).  A guide within the body (114) limits movement of the blade (120) to a linear path between a position wherein the cutting edge projects into the crevice (118) in the direction of the width thereof and a position wherein the cutting edge is withdrawn from the crevice (118).  A dial (184) is eccentrically mounted on the body (114) in the path of movement of a slide (124) and is rotatable to adjustably limit the extent of projection of the cutting edge (122) of the blade (120) into the crevice (18).  The dial prevents the blade from spanning the crevice entirely.

Abstract: ABSTRACT             The invention relates to a method and apparatus for the automatic visual inspection, of at least partly specularly reflective surfaces, such as metal surfaces, especially those in continuous motion by means of a receiver and image-analysis equipment.  The apparatus includes a light source consisting of an incandescent bulb having a         lens positioned in front of it and a camera with an image analysis device.  The light from the light source is adapted to be reflected from the object being inspsected to produce an image which is received by the camera and analyzed  by the image analysis device.  In order to eliminate the uneven illumination caused by variation in the height and orienta-tion of the surface being inspected the view angle of the camera can be regulated by adjusting the length of the incandescent bulb or by adjusting the aperture in front of the light source.

Title: Buoyant coarse media flocculator
Inventor: SCHULZ CHRISTOPHER R
IPC: C02F1/52
Filed: 1989-09-08
Granted: 1994-03-08
Abstract: ABSTRACT A coarse media flocculator utilizes buoyant media restrained against upward movement in a vertical chamber whose cross-sectional area increases uniformly in the direction of flow, thereby providing a uniformly tapering velocity gradient. The height of the media restrainer within the chamber can be adjusted, thereby changing the depth and cross-sectional characteristics of the media bed within the tapered chamber. The velocity gradients of the flocculator can thus be changed independent of flow. A washwater piping grid with downwardly pointed jet spray nozzles is positioned within the media bed for cleaning. The height of the media bed can be adjusted by changing the position of the media restrainer or by changing the liquid level within the chamber, thus changing that part of the media bed wherein the jet spray is concentrated. In one embodi-ment, the restrainer is disposed within an area of the chamber above the tapered portion having a uniform cross section. This arrangement facilitates adjustment of the position of the re-strainer and also facilitates cleaning by allowing the restrainer to be repeatedly pushed downwardly, thereby pulsating the media bed. In a second embodiment, a two-piece restrainer is disposed within the tapered portion of the chamber and is adjustable in one dimension. This arrangement allows the cross-sectional and consequent flocculation parameters to be adjusted in both upper and lower portions of the media bed.
