Title: Friction-drive carriage type conveyor
Inventor: TADA SHOJI
IPC: B65G35/06
Filed: 2004-08-11
Abstract: A friction-drive carriage type conveyor includes a carriage 1 so supported as to run in a running direction along a track, which includes a linear path and a turning path 18. The carriage 1 has a frictional surface 6a continuing linearly along its whole length. The conveyor is fitted with first friction drive rollers 15 for contact With the frictional surface 6a, which are positioned near the linear path. The conveyor is also fitted with second friction drive rollers 15A - 15C for driving the carriage 1 smoothly and reliably even along the turning path 18. The second friction drive rollers 15A - 15C are spaced at intervals along the turning path 18, which are shorter than the frictional surface 6a. The second friction drive rollers 15A - 15C are so supported that each of them can move between an advance limit position and a retraction limit position. The advance limit position is on the locus described by the frictional surface 6a when the carriage 1 passes along the turning path 18. The retraction limit position is outside the locus. Each of the second friction drive rollers 15A - 15C can be biased toward the associated advance limit position by a biasing means, which may be a hydraulic cylinder 25. Each of the second friction drive rollers 15A - 15C comes into compressive contact with the frictional surface 6a of the carriage 1 driven forward by the just upward friction drive roller and drives the carriage to a position where the frictional surface comes into compressive contact with at least the just downstream friction drive roller.

Title: Designs, interfaces, and policies for systems that enhance communication and minimize disruption by encoding preferences and situations
Inventor: SUBRAMANI MURUGESAN S
IPC: G06Q10/10
Filed: 2004-09-14
Abstract: The present invention relates to utilizing identity and context-sensitive decision-making for handling communications, including, channel selection, routing, and rescheduling operations. The systems and methods provide a service that allows users to assess preferences regarding real-time call handling and performs dynamic decision-making about the best timing and channel for interpersonal communication. This service can be based on various cost-benefit analyses (e.g., basic and extended) that consider cost of interruption and preferences of contactors and contactees to guide communications, and/or on decision-making under uncertainty. Statistical models that are learned from data are joined with user preferences to generate expected costs of interruption for office activity and over time, based on a user's activities, locations, calendar information and preference assessments. In addition, statistical forecasting provides presence and availability predictions. The foregoing can provide an enhanced interpersonal communication system that can maximize the value and minimize the cost of communication among people.

Title: Wheel chock
Inventor: FORBIS CHARLES
IPC: B60T3/00
Filed: 2004-10-07
Abstract: A wheel chock (10) configured for placement under a resting rubber tired wheel (W), such as a wheel found on a powered vehicle, to maintain the wheel (W) at rest is disclosed. The wheel chock (10) broadly includes a body (12) that defines an internal chamber (14) in communication with an open face (16) presented by the body (12). The body (12) presents a prism-like configuration having a generally triangular shape and includes a pair of oppositely spaced sidewalls (18, 20), a rear wall (22) extending between and adjoining the sidewalls (18,20), and a wheel-supporting surface (24) extending between and thereby enclosing the walls (18,20,22). The wheel-supporting surface (24) presents a low profile, arcuate leading tire-engaging edge (34). The arcuate leading edge (34) substantially complements the contour of the tire and enables the chock (10) to be easily placed under the wheel (W) in an optimal operating position-i.e., in close adjacent alignment with the wheel (W) so that at least a portion of the majority of the circumferentially extending treads of the rubber tire of the wheel (W) engage at least a portion of the chock (10) -with a minimal exertion of force and effort by the user. The internal chamber (14) in communication with the open face (16) enables the body (12) of the chock (10) to be stackably nested within another similarly configured wheel chock to provide a compact, space-efficient storage of the chocks that facilitates ready portability for transportation of a pair or more of the chocks in the vehicle.

Inventor: BOTSTEIN DAVID
IPC: C12P21/08
Filed: 2000-05-15
Abstract: The invention concerns compositions and methods for the diagnosis and treatment of neoplastic cell growth and proliferation in mammals, including humans. The invention is based upon the identification of genes that are amplified in the genome of tumor cells. Such gene amplification is expected to be associated with the overexpression of the gene product as compared to normal cells of the same tissue type and contribute to tumorigenesis.  Accordingly, the proteins encoded by the amplified genes are believed to be useful targets for the diagnosis and/or treatment (including prevention) of certain cancers, and may act as predictors of the prognosis of tumor treatment. The present invention is directed to novel polypeptides and to nucleic acid molecules encoding those polypeptides. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention.
