Abstract: The present invention relates to novel porphyrin derivates of formula (I), especially to porphyrins which carry substituted phenyl moieties in meso-position. The porphyrin derivates of the invention are useful as photosensitizers in photodynamic therapy (PDT), especially in photodynamic tumor therapy. Due to their excellent photophysical properties the compounds of formula I are extremely efficient in photodynamic treatment.

Abstract: In a reproduction machine, a static elimination device for removing static charge from a sheet of material being conveyed along a sheet path through a sheet handling machine. The static elimination device includes a thin flexible support member having a first length suitable for spanning across the sheet path, and a first width defining an area with the first length for supporting a static charge removing member. The static charge removing member has a second length substantially equal to the first length of the support member, and a second width greater than the first width of the support member, and is mounted to the support member. In particular, the static removing member comprises a conductive fabric for mounting in a static removing relationship with a sheet being conveyed along the sheet path of the sheet handling machine. The fabric consists of innumerable thin fibers forming fabric segments.

Abstract: In a reproduction machine, a user clearable convenience stapler assembly. The convenience stapler assembly includes a stapling apparatus having a stapler head for stapling together a set of copy sheets, and a mounting assembly for mounting and supporting the stapling apparatus to a portion of a frame of the reproduction machine. The stapling apparatus is mounted and supported such that staple jams within the stapler head are clearable by an ordinary user of the reproduction machine. The mounting assembly includes a pivot plate sub-assembly for mounting to the stapling apparatus, and a support sub-assembly for supporting the pivot plate sub-assembly and the stapling apparatus in a stapling position and in a jam clearing position. The pivot plate sub-assembly has integrally formed therein hinge tabs for forming part of a pivot assembly for the stapling apparatus and pivot plate sub-assembly, and a latching aperture for receiving a latching stop member from the support sub-assembly.

Abstract: Reducing the operating impact noise of a moving bins sorter of the type in which the bins of the sorter are sequentially incremented with a rotatable open mouthed "C" cam drive, where the open ends of the "C" cam on opposite sides of the open mouth provide operative bin engaging cam surfaces for engaging a cam engaging portion of the bins, without adversely affecting the contacting surfaces wear rate, by providing cantilevered arms of limited flexibility supporting the bin engaging end portions of the "C" cam to provide limited flexing of at least one of the bin engaging end portions of the "C" cam when at least one of these bin engaging end portions operatively engages a bin, for impact noise reduction. The "C" cam may further include an internal chordal cross brace.

Abstract: A corona generating device having an elongated generally U-shaped shield and a corona wire mounted within and extending along the length of the shield has an improved cleaning apparatus for cleaning both the interior surface of the shield and the wire. The cleaning apparatus includes a block slidably mounted within the shield so that the block can be moved back and forth along the shield, and a disposable cap which locks onto the block over the corona wire. The cap has cleaning pads mounted thereon for cleaning the interior surface of the shield, and a protrusion and recess are used to lock the cap onto the block in an operative position in which the cleaning pads contact the interior surface to be cleaned. Separate disposable pads for cleaning the corona wire are located between the block and cap, and when the cap is replaced, these wire cleaning pads are replaced also.
