Abstract: A process for increasing the crystalline content of an amorphous or a semi-amorphous crystallizable thermoplastic resins is disclosed. The process entails heating the resin by Infra-red heating. The thus modified resin is then more suitable for drying at a high temperature. The dried resin, in pellets form, is characterized by its flowability and the article molded has better properties than does a corresponding article made from an unmodified resins.

Abstract: The blasting gun for compressed air, in which a dynamic effect of the air is utilized for removing dirt and for cleaning purposes, comprises a built-in oscillator seat valve for producing a pulsating air stream with periodically repeated pressure discharges at a frequency of the order of 2-50 Hz thus causing the valve alternately to open and close an air flow through the blasting gun, this oscillator seat valve comprising a longitudinally displaceable oblong valve body having an end for shutting off the air flow through an air outlet of the gun by resting in contact against a valve seat under the influence of a compression spring, the oblong valve body having another end embodied as a piston displaceable through a closed cylinder. The piston separates an inner volume of the cylinder into two complementary back and front portions, the back portion of the volume being connected to the air outlet which is located on an outer side of the valve seat via a longitudinal bore through the valve body, the front portion of the volume being connected to a pressurized air chamber located on an inner side of the valve seat via a duct.

Abstract: A base station includes a call-terminated terminal identification message generating portion. When the base station transmits a call termination message to a terminal, a call-terminated terminal identification message useful for only the call-terminated terminal, for example a message such as ID number information peculiar to the terminal, is inserted in the head of a slot assigned to the terminal and is transmitted. When the call-terminated terminal detects the call-terminated terminal identification message, the terminal receives a regular call termination message transmitted thereafter. When the terminal cannot detect the call-terminated terminal identification message, the terminal judges that the message is not directed to call its own terminal and immediately stops monitoring of the slot at this time.

Abstract: An idler system that is both self-centering and self-aligning with a drive roll. The idler assembly consists of a pair of rolls connected by a shaft, the shaft being supported in a housing. The housing is retained by a resilient spring member which member allows the axis of rotation of the idler rolls to pivot in more than one plane simultaneously. This pivoting causes the axis of rotation of the idler assembly to align parallel with the drive roll axis. The single spring also provides an even loading of the normal force across the width of the drive nip. As a result of the alignment and even loading, skewing of a sheet is prevented as it is driven through the nip formed by the drive roll and the idler roll. The resilient spring mounting also allows for easy replaceability of the idler assembly and the housing is easily locatable between tabs formed in the frame of the machine for mounting the idler assembly therein. The housing provides a guide from the mounting frame into the nip and from the nip into the downstream paper path for increased capacity to handle curled and/or damaged cut sheet media.

Abstract: A vent system for exhausting gas generated within a battery case is provided. The vent system exhausts gas from the battery case (12) while maintaining the hermetic seal of the case. The vent system provides a small gas exit hole (16) that is sufficiently small to prevent electrolyte leakage and also intake of excess carbon dioxide or excess water vapor from the atmosphere. Also,various combinations of gas-permeable, hydrophobic membranes (40, 44) and diffuser material (42) may cover the gas exit hole to provide humidity control for the battery while exhausting gases from the battery. A recess (36) may be provided within the case such that the gas exit hole communicates between the atmosphere and the recess. Also, various combinations of gas-permeable, hydrophobic membranes (40, 44) and diffuser (42) material may cover the recess and gas exit hole to provide humidity control for the battery while exhausting gases from the battery case. The present invention also provides a vent system in which gas-permeable, hydrophobic membranes and diffuser material may fill an opening so as to exhaust gas from the case. The present invention also provides an electrode lead (39) which extends along the battery case and through the seam (34) of the battery case in a manner in which a hermetic seal is provided aroundthe lead. The manufacturing process for the seal around the lead is relatively simple.

Granted: 2000-11-14
Abstract: A spray assembly for a dishwasher includes a fluid pump and a spray tower.  The spray tower includes a lower stationary member and an upper rotatable member and includes a fluid cavity therein.  The rotatable member has at least one spray opening adjacent its upper end.  A spray nozzle directs a stream of washing fluid upwardly into the spray tower and moves the stream of washing fluid in a circular pattern.  The stream of water engages the upper rotatable member of the spray tower and the upper rotatable member rotates in response thereto.  One form of the invention uses a deflecting surface on the rotatable member for causing rotational movement of the rotatable member and for causing precession of the rotatable member.  Another modification of the present invention utilizes a pair of intermeshing gears for causing precession of the rotatable member.

Abstract: Batterie à ions lithium comprenant une électrode négative, un solvant non aqueux et une électrode positive comportant du LiV2O5 mélangé à une matière conductrice. Cette dernière est constituée de préférence de carbone en une quantité comprise entre environ 2 % et environ 20 % en poids de l'électrode positive, de préférence 10 % en poids. On forme le LiV2O5 en déversant un mélange de V2O5 et de matière conductrice dans un réacteur électrochimique avec une électrode négative en lithium métallique, où un sel électrolyte dans un solvant non aqueux réduit ledit mélange d'un Faraday par mole de V2O5 afin de convertir la totalité du V2O5. L'élément est déchargé de préférence à environ 2,8 volts pour former l'électrode positive en LiV2O5, que l'on enlève ensuite pour lui donner une forme d'électrode prédéterminée afin de l'utiliser comme électrode positive dans un élément dépourvu de lithium métallique.

Un capteur de pression (36) détecte indirectement la pression du fluide dans la vessie par l'intermédiaire d'une pression d'un tampon (38) venant en contact avec la paroi de la vessie. Un circuit de commande (34) produit un signal de pression en réaction au déplacement du tampon presseur (38) pour commander une soupape (30) qui dirige le fluide entre la pompe et la vessie. Un pointe distributrice (68) permet l'interconnexion d'un orifice distributeur (64) de la poche en communication fluidique avec la tubulure.
