Patent CA-2300684-A1 (CA)
Title: Robotic end effector with counter-rotating fingers
Inventor: GRAMS ROBERT S
IPC: B65G47/90
Filed: 2000-03-14
Abstract: An improved end effector for use with a robot includes a pair of carriages.  Each carriage supports a pair of fingers and at least one actuator. Each actuator is interconnected with the associated pair of fingers to counter-rotate the fingers.  One or both of the carriages is movable toward the other carriage to engage trays on a conveyor system with the fingers. The robot moves the end effector between the conveyor system and shipping containers for shipping the trays. Because the pairs of fingers counter-rotate, the friction forces between each finger and the tray is offset by the friction forces between the other finger in the pair and the tray.  The improved end effector thereby maintains trays substantially in the desired stacking orientation within the shipping container. Preferably, an actuator is provided for each finger. A change-out mechanism may also be provided to facilitate replacing the fingers.

Title: Collision avoidance using gps device and train proximity detector
Inventor: ERICK JACK M
IPC: G01S19/48
Filed: 1998-08-18
Abstract: A processor (12) located on a vehicle processes GPS coordinates input thereto to provide an area of protection around the vehicle. Railroad grade crossing data (82, 84) stored in a data base (30) is read therefrom to ascertain whether a grade crossing is within the area of protection. If so, heading data (86) stored in association with the grade crossing data (82, 84) is compared with the heading of the vehicle to determine if the vehicle is on a road that intersects the grade crossing.  If so, a first level alert is provided to the vehicle operator. If, in addition, a train is in the vicinity of the crossing, a second level alert is provided to the operator of the vehicle.

Filed: 2000-04-13
Abstract: The casting chamber for a die casting machine includes a casting chamber jacket in which, over its entire length, there is provided an inner jacket defining the sliding surface for the pressure piston. In order for excessive heat in the inner jacket to be uniformly distributed and passed to the casting chamber jacket, copper rings are inserted in the inner jacket (3), the latter being pressed against the casting chamber jacket by means of screws threaded into a conical wedge.

Abstract: The present invention provides a system, method and apparatus for modifying persistent storage. In an embodiment of the invention, the persistent storage within a radio phone contains a telephone directory. The telephone directory in the radio phone can be used to automatically dial the number of an individual or entity that exists as an entry in the telephone directory. The phone is operable to send and receive, via a radio base station respective to the radio phone, copies of the telephone directory. A remote client-device, such as a personal computer, is operable to allow a user to modify the telephone directory and to exchange copies of the telephone directory with the radio phone. The present invention thus provides a user-friendly way to backup, modify and restore a telephone directory or other electronic information in a radio phone or other intelligent devices which typically have limited user-interface capabilities.

Abstract: The invention relates to a dispenser (11) for discharging, especially spraying media, especially liquid medicaments. The inventive dispenser discharges a desired quantity of the medicament in just one or optionally, a few strokes. The user can operate the dispenser with three fingers, the thumb pressing an activating depressor (80) in the direction of activation and discharge. The aim of the invention is to prevent the dispenser from being activated unintentionally and to protect the discharge opening (44) against dirt and contamination. To this end, a protective cap (90) which covers the entire discharge section (13) and the holding surfaces (14) for operating the dispenser is provided. Said protective cap also has rod-shaped projections (93) which extend as far as the activating depressor (80) and fix said depressor in place so that the dispenser cannot be activated whilst the protective cap is on. Removing the protective cap, which is fixed in place with a snap connection, unblocks the activating mechanism.

Title: Modified atmosphere package with accelerated reduction of oxygen level in meat compartment
Inventor: NORBY ALLEN J
IPC: B65D81/26
Filed: 1999-03-26
Abstract: A modified atmosphere package includes first and second compartments separated by a partition member that is substantially permeable to oxygen. The first compartment contains an oxygen scavenger activated with an oxygen scavenger accelerator. The second compartment contains a retail cut of raw meat. Various techniques are employed to rapidly reduce the oxygen level in the second compartment below pigment sensitive levels so that the growth of metmyoglobin is inhibited. Some of these techniques increase the flow of oxygen from the second compartment to the first compartment through the partition member, while other techniques directly absorb oxygen within the second compartment.

Title: System of currents for compensating the magnetic field produced by electrically driven trains
Inventor: RIVERO RODRIGUEZ GUILLERMO
IPC: B60M1/06
Filed: 2000-02-03
Abstract: The invention relates to a device that can compensate at the point of origin disturbances of the magnetic field in the surroundings of a railway line caused by fluctuations in the current of the power supply catenary. Said system aims at creating a return circuit whose geometry varies depending on the position of the train and which suppresses at the point of origin the field produced by the catenary-train-track and reduces disturbances in the magnetic field in the surroundings. The system is based on deriving the return current from the track that is divided into elementary segments isolated from one another to a return conductor located adjacent and parallel to the catenary by means of a series of vertical conductors connecting each segment to the return conductor.
