Inventor: BALABAN DAVID B
IPC: H02H5/04
Filed: 1998-06-08
Abstract: An electrical cord including over-temperature protection including a sensor adjacent an electrical conductor that detects over-temperatures and generates a sensor control signal. An interrupter electrically responsive to the sensor control signal defines the state of conductivity of the electrical conductor in accordance with the sensor control signal. Accordingly, the electrical cord may be made nonconductive when over-temperatures are sensed by the sensor. The sensor is a temperature sensitive material that has a positive temperature coefficient which exhibits changes in resistance in response to a change in temperature. Further described is a cable providing over-temperatureprotection which comprises temperature sensitive material disposed adjacent a conductor and a sense wire in the cable. An interrupt circuit interrupts electrical power to a load in accordance with temperature changes detected between the conductor and sense wire. Further, a cable for providing over-temperature protection for a load is described wherein over-temperature sensors are located within a load and power is interrupted to the load when a sensor of the cable detects over-temperatures. The cable may power the load. The electrical cord may be an extension cord or an appliance cord. The sensor may be a continuous fiber nearly the length of the cord or cable. Alternatively, multiple sensors connected in series may be employed.

Inventor: FELS HARALD
IPC: F24F6/04
Filed: 1998-09-22
Abstract: This invention relates to a method and an apparatus for humidifying a room. The apparatus is a decorative humidifier comprising a water reservoir, a porous body and pumping means for pumping water from the reservoir to the top of the porous body thereby increasing the surface area over which the water flows. The water then runs down the porous body by gravity infiltrating the pores of the porous body and increasing the surface area over which the water flows. The increase in surface area over which the water flows increases the efficiency of water evaporation and enhances the ambient air humidity without any mechanical means.

Abstract: A system for providing synchronization and information exchange in a network such as a digital television broadcast network using a network management operations and control paradigm. A management entity component, such as a computer workstation operated at a control center, coordinates the actions of different agent components, such as hardware used at the headend or uplink site of a television network. The agent components are used to provide conditional access to a television signal by inserting conditional access data into the transmitted programming. Management information bases (MIBs) are provided for the agent components and the management component. The agent components update their MIBs with information of the communication network, such as changes in a television event schedule. The management component periodically reads the agents' MIBs to obtain the updated information and store it in its own MIB. The management component provides information to the agents' MIBs according to the updated information obtained from the agents to synchronize the insertion of data into the digital broadcast data stream by the agents.

Title: Light emitting diode retrofitting lamps for illuminated traffic signs
Inventor: WU CHEN H
IPC: G09F13/04
Filed: 1999-02-09
Abstract: A light emitting diode (LED) retrofit lamp with locking swivel mount that mounts into a threaded screw-in electrical socket of a traffic signal.  The LED lamp includes a socket housing, a printed circuit board and a plurality of light emitting diodes. The socket housing has a lower end terminating in a threaded base for insertion into a threaded screw-in electrical socket. The printed circuit board is rotatably mounted to the socket housing. The plurality of light emitting diodes is mounted on the printed circuit in such a manner that they form a symbol image, such as an arrow, a pedestrian walking, a hand, a letter or even words. The printed circuit board is rotatable relative to the socket housing for rotation of the symbol image formed by the light emitting diodes to a desired rotational orientation relative to the socket housing. Therefore, once the threaded base is fully inserted into the threaded screw-in electrical socket of a traffic signal, the printed circuit board can be rotated relative to the socket housing so that the symbol image is properly oriented.
Patent CA-2262503-A1 (CA)
Inventor: WOLTMAN GARRY ROLAND
IPC: A61L15/20
Filed: 1997-08-11
Abstract: L'invention porte sur une structure améliorée qui inclut un voile de fibres non tissé comprenant un traitement de visco-élasticité. Le voile de fibres traité, lorsqu'il est mis au contact d'un fluide visco-élastique tel que des menstrues, modifie les propriétés du fluide et améliore son imbibition par capillarité et sa répartition sur toute la structure d'absorption. Un matériau visco-élastique souhaitable est un polyglycoside d'alkyle, en particulier un polyglycoside d'alkyle ayant 8 à 10 atomes de carbone dans la chaîne alkyle. Lorsque ledit matériau est appliqué de manière à produire une quantité d'environ 0,1 % à environ 5,0 % de matières sèches complémentaires par rapport au poids du voile de fibres non tissé, on peut obtenir une imbibition et une répartition de fluide rapides. L'invention porte sur d'autres matériaux visco-élastiques. Pour un meilleur résultat, le traitement peut être appliqué sous forme de composition à haute teneur en matières sèches, par des moyens d'application classiques tels que des applicateurs de revêtement par pulvérisation ou autres, ou comme produit d'addition interne. La structure d'absorption est particulièrement utile comme élément de couche de répartition d'une serviette hygiénique, pour l'absoption de mentrues ainsi que d'autres produits de manipulation du sang tels que des champs, par exemple.

IPC: A61L2/12
Filed: 1999-03-16
Abstract: When a medical instrument is sterilized by subjecting it to microwave radiation in a container comprising a susceptor that converts the radiation into heat, the tendency of the instrument to arc can be reduced by vacuum sealing the container. When the container is a pouch made from a flexible material, the vacuum sealing causes the material to intimately contact the medical instrument, thereby increasing the rate at which heat is transferred from the material to the instrument.
