Abstract: A collator (10) collates folded signatures (30). A conveyor (12) of the collator (10) moves a plurality of support saddles (20). The support saddles (20) receive and support the signatures (30) with their folds extending in a direction perpendicular to a movement direction (18) of the support saddles. A feed mechanism (40) feeds a signature (30) down toward a respective support saddle (20) as the conveyor (12) moves the support saddles. The signature (30) falls vertically toward the respective support saddle (20). An air handler (66) draws air down, vertically relative to the respective support saddle (20) to minimize air resistance acting against the signature (30) being fed to the respective support saddle (20).

Patent CA-2260078-A1 (CA)
Title: Method of making injection molded orthotics
Inventor: MARSHALL SCOTT
IPC: A43D1/02
Filed: 1997-08-13
Abstract: A method of making functional orthotics from a multiplicity of uniquely designed injection molds which have been constructed by studying large numbers of replicas produced from uncorrected replicas that replicate the contour of the feet of a multiplicity of patients. In one form of the method of the invention, following a careful dimensional study of the corrected replicas, they are grouped into families, the members of which exhibit lower surface contours that are substantially identical. An injection mold is then made for each of the identified families, in a manner such that the mold will produce an orthotic having an upper surface that corresponds to the lower surface of the corrected orthotic that makes up the group. Companion data is then developed which correlates the corrected replicas of each identified family with the uncorrected replicas from which they were made. A study of the uncorrected replicas then provides data as to the contour of the patient's feet which they replicate. This data can then be compared with new patient data provided by the prescribing doctor and the mold can be selected which will produce an injection molded orthotic which is appropriate for the particular patient.

Title: Communication system capable of displaying addresser information and method for displaying addresser-related information
Inventor: NAGASHIMA KUNIO
IPC: H04M1/57
Filed: 1999-01-29
Abstract: A communication system of the present invention retrieves first relevant information for an addresser according to received addresser information out of a storage circuit 14 and displays the first relevant information in a second window different from the first window and having a display priority higher than that of a first window of a first processing based on an application program in the program memory 16. In this case, the control circuit 12 keeps a display focus in the first window. Thereby, it is possible to display only the necessary and minimum addresser information without influencing an application currently used when a call is received. Moreover, the present invention can be constituted so as to display first relevant information in a tool bar.

Title: Dual purpose input electrode structure for miocs (multi-function integrated optics chips)
Inventor: ZIMMERMAN GREGORY A
IPC: G02F1/313
Filed: 1999-07-28
Abstract: An Integrated Optics Chip with improved performance when exposed to rapidly changing temperature is disclosed. The optic chip or integrated optic chip or MIOC has a top surface, a +Z face and -Z face. The chip is formed from a crystal having a high electro-optic coefficient such as Lithium Niobate. For the purpose of orienting the components to the optic chip to be described, the +Z crystal axis extends outward from the +Z face. An input waveguide formed in the top surface of the chip and orthogonal to the +Z axis receives an optical signal from an input port, passes the signal via a waveguide network, to an output waveguide coupling the waveguide network to an output port. Metalization is applied to the top face of the optic chip to form at least a first and a second rail. The first and second rails are positioned to very closely straddle a portion of the input waveguide. A conductive bridge connects the first and second rails to prevent a charge differential from developing between the first and second rails.
