Abstract: A mechanism is provided for receiving a web with intermittent motion and converting it to constant motion, particularly for severed carton items. A reciprocating carriage has first and second adjacent idler rollers and a third roller spaced away from the first two. A driven roller has a fixed axis and is located with respect to the third idler roller such that the web when stung between the first and second rollers and thence around the third roller and thence around the driven roller, assumes a quasi-boustrophedonic configuration such that a portion of the web can be accumulated  between the third idler roller and the driven roller when the carriage moves in the direction which increases the distance between them. Upper and lower endless belts pass partially around the first and second translating rollers respectively and once juxtapositioned, between the two idler rollers, thence around the thirdtranslating idler roller, thence around the driven roller, thence along different respective return paths. The driven roller is rotated at substantially constant speed, and the carriage is moved in a first direction corresponding to that portion of the cycle when the web movement has been arrested, and for moving the carriage in the second direction opposite the first direction when web movement resumes.

Title: Positive photoactive compounds based on 2,6-dinitrobenzyl groups
IPC: A61K9/00
Filed: 1995-06-29
Abstract: The present invention is an approach to positive acting photochemistry which yields a substantial improvement in quantum efficiency by the use of photoreactive compounds synthesized from monomers including:    where X and Y may be the same or different member selected from the group consisting of: halogen, -OH, -OR, -O-SO2R, -SR, and NRR'. R and R' may be hydrogen or any of a wide variety of organic substituents, including substituted or unsubstituted alkyl, aryl, or aralkyl substitutents. If further reaction to form adducts or polymers is desired, the R or R' groups may include a reactive group such as a hydroxyl group. After exposure to radiation such as ultraviolet light, the bond is broken between the carbon and the X in the CH2X group, thus providing photoactivity to the compounds of the present invention.

Title: Method and system for dynamically establishing field size coincidence
Inventor: HUGHES JOHN H
IPC: A61N5/10
Filed: 1997-08-08
Abstract: A method of establishing coincidence between a field size of a light field used in a setup mode of a radiation system and a field size of a radiation field used in an operation mode of the system includes providing automatic adjustment of field-defining structure to compensate for differences in optical properties of the light and the radiation. A light beam passing through the field-defining structure typically exhibits greater scattering than an X-ray beam passing through the structure. For each of a number of different settings of the field-defining structure, the difference between the field sizes of the light and the radiation are determined and recorded. Then, for a particular desired field size, the field-defining structure can be automatically adjusted to provide compensation. In the preferred embodiment, the field-defining structure includes jaws of a collimator of a radiation system and the determination of field size differences of the light and the radiation occurs for each of various energy level settings of the radiation system.

Abstract: An adjustable radius form assembly is provided which includes a plurality of vertical strongbacks and a plurality of horizontal walers. Each of the walers are pre-rolled to a desired radius. The walers are then connected to one another by ball and socket type adjusters which enable the end to end arrangement of the walers to accommodate an overall form assembly having a wide range of curvatures or radii. The plurality of end to end walers and plurality of corresponding strongbacks may define a gang form length. A number of gang form lengths may be connected to one another to create the desired form assembly for the structure to be constructed. The vertical strongbacks may be placed at desired spacings along the horizontal lengths of the corresponding walers by adjustment of connectors on said strongbacks extending through slotted plates on the walers. The exact number and spacing of walers and strongbacks used in the form assembly are dictated by the size and strength requirements of the structure to be constructed.
