Abstract:
Adhesive material from the fimbriae (esp. Type 1) of bacteria or synthetic analogues or fragments thereof is combined with a drug to provide for attachment to the gut of a mammal, thereby prolonging the transit time of the drug through the gut. The 28 kDa polypeptide from E. coli Type 1 fimbriae is the preferred adhesive material (“adhesin”). The drug is presented in a carrier such as albumin, a polylactide/glycolide copolymer or alginate microcapsules. The adhesin may be incorporated in the carrier during preparation thereof, adsorbed onto the carrier after preparation, or covalently linked thereto, for example with carbodiimide.
Abstract:
A light source module for use with a multi-camera array in a video surface inspection system includes a first light emitter which extends lengthwise across the entire width of a sheet to be inspected. Light from the first light emitter, which preferably comprises one or more fluorescent lamps, is received by a light guide and carried by the guide to uniformly illuminate a band extending entirely across the width of the moving sheet. The light guide comprises a transparent thermoplastic such that the light receiving end of the guide can be bent to define a plurality of sections which can be axially aligned with a corresponding plurality of fluorescent lamps. The fluorescent lamps may be powered by individual inverter ballasts which may be driven inturn by one or more variable dc power supplied to control the intensity of light emitted by the lamps. The light source module can also assist the inspection system in overcoming redundant data processing problems by providing second light emitters which illuminate the sheet in overlapping portions of the field of view of adjacent cameras of the multi-camera array to define data dividing points. Accordingly, duplicated data generated by the video cameras can be divided among the cameras at the defined data dividing points such that duplicated data is only processed once by the video surface inspection system.
Abstract:
A gauging apparatus for sheet materials and the like comprises a surface follower body (14,20,30) adapted to be constrained without substantial solid bodily contact and guided (e.g., by gas bearings between 32 and 36 and 38) for movement along a surface follower path that intersects the path of a traveling sheet (10) to be gauged. The body has a passage (46) adapted to carry a flow of pressurized gas to be discharged against one surface of the sheet. The discharge of the gas is effective when the body is at a predetermined distance from the surface to generate a levitating force (on 20) urging the body away from the sheet surface. Means (70,64,62) responsive to the pressure of the gas in the passage exerts on the body (at 64) a counteracting force that tends to move the body closer to the surface. The counteracting force increases when the pressure increases and decreases when the pressure decreases, and coacts with the levitating force in such a manner that the predetermined distance of the body from the surface is normally maintained substantially constant and is relatively unaffected by minor variations in the pressure of the gas in the passage.
Abstract:
A property of a thin, infrared radiation-transmissive film of plastic or the like with specular surfaces is measured with substantial freedom from errors caused by wave interference effects, utilizing first and second infrared radiations having wavelengths selected so that one of the radiations is subject to greater absorption in the film material than the other radiation. Beams of each of the radiations are directed from a multiplicity of points as on the diffusively reflective inner surface of a sphere to a surface of the film at a broad spectrum of incidence angles so that the beams traverse a multiplicity of paths through the film constituting a broad spectrum of path lengths. Radiations leaving the film are intercepted and redirected from a multiplicity of points to a surface of the film at a broad spectrum of incidence angles so that the redirected radiations also traverse a multiplicity of paths through the film constituting a broad spectrum of path lengths. Each of the first and second radiations are detected with detecting means so arranged with respect to the directing and redirecting points that detected components of each radiation are added at substantially all possible phase angles and so that the components of each of the respective radiations at each of the possible phase angles approach equality of intensity as detected by the detecting means. A response produced is indicative of the film property as a function of the ratio of the detected intensities of the first and second infrared radiations.

Abstract:
An in-situ technique is provided for automatically verifying proper operation of a photometric device, such as a cell density probe (CDP). The CDP has a first detector and a second detector. The first detector senses light that is transmitted from a light source of the CDP. The second detector senses light that has passed through an optical gap at a tip of the CDP, wherein the sensed light has been reduced in intensity due to light absorption. Electrical current provided to the light source is reduced, and the resultant values of a light characteristic (such as intensity) at the first and second detectors are sensed. These values from the detectors are compared against one or more predicted values. If the CDP is operating properly, the values from the detectors will be consistent with the predicted values. If there is a malfunction in the CDP, then the values from the detectors will be inconsistent with the predicted values.
