Abstract: A lithium storage battery having a high energy density and preferred electrical charge/discharge performance is produced to prevent a short circuit that may be caused by dendrite produced from the negative electrode. The lithium storage battery comprises an electrolyte layer, a positive electrode, and a negative electrode consisting of a lithiu m- containing material. The electrolyte layer consists of an inorganic solid electrolyte, and a positive electrode contains an organic polymer. Preferably, the electrolyte layer contains at least one element chosen from a group that consists of oxygen, sulfur, nitrogen, sulfide and oxynitride. Preferably, the lithium ion conductivity of the organic electrolytic solution of the positive electrode is lower than that of the inorganic solid electrolyte of the electrolyte layer.

Title: Low friction doctor blade
Inventor: NEWMAN BENJAMIN KEITH
IPC: G03G15/08
Filed: 2000-09-21
Granted: 2005-06-21
Abstract: A device within an image forming apparatus for positioning a doctor blade against a developer roller and preventing toner leakage. The device includes a developer housing for containing the developer roller and the doctor blade. A biasing member is positioned adjacent to the doctor blade for forcing the doctor blade against the developer roller for controlling the mass flow and charge level of the toner. The doctor blade is supported by retention stops on a front edge and a pair of supports on the back edge. Toner is prevented from leaking through the device by a flap seal positioned along the doctor blade back side and a seal positioned between each end of doctor blade end and developer housing. The invention provides for the doctor blade to be freely positioned between the retention stops, developer housing, and seals providing for the doctor blade to contact the developer roller in a consistent manner.

Abstract: Dispositif expansible (20) pour support de tissus, qui comporte des charnières ductiles (32) à des sites choisis dudit dispositif. Lorsque des forces d'expansion sont appliquées au dispositif dans son intégralité, les charnières ductiles concentrent les contraintes et forces d'expansion en de petites zones bien définies. Ledit dispositif comportant des charnières ductiles fournit les avantages suivants: faibles forces d'expansion requises, parois relativement épaisses qui sont radio-opaques, propriétés améliorées de jonction par serrage, forte résistance à l'écrasement, retour élastique réduit après implantation, et régulation des contraintes à un niveau désiré. Ledit dispositif comporte une pluralité de barrettes allongées disposées en un dispositif cylindrique et connectées par une pluralité de charnières ductiles. Bien que de nombreuses configurations soient possibles pour les charnières ductiles, ces dernières possèdent de préférence une superficie de section transversale pratiquement constante qui est inférieure à une superficie de section transversale des barrettes, si bien qu'en cas d'expansion du dispositif d'un premier diamètre à un second diamètre, les charnières ductiles connaissent une déformation plastique tandis que les barrettes ne subissent pas de déformation plastique.

Patent CA-2333948-C (CA)

Granted: 2008-09-16
Abstract: A thick walled Moineau-style stator (320) and method of manufacture are disclosed. The outer profile (355) of the stator follows the inner helical profile (353) of the stator.  The application of an elastomeric layer (330) to the inner profile of the stator results in a constant thickness for the elastomeric layer and proximity for the walls of the stator. This improves the durability of the motor because of lower heat generation and better heat dissipation. The stator walls also support the elastomeric layer. Further, the thick walls of the preferred stator eliminate the need for additional drill piping or other support provided adjacent the stator.  Thus, the cost of additional piping and difficulties placing a stator inside drill pipe or drill string housing are eliminated. Further, the improved strength of thick wall steel when contrasted to a thin wall counterpart allows a higher operating pressure drop for a given stator length, resulting in a higher power output. Moreover, the undulating outer profile of the stator provides a distinctive appearance to the stator piping.

Abstract: A method and apparatus for determining position in a pipe provides for the precise determination of location and associated characteristics of each pipe joint of a well, cross country pipeline or other fluid transmission line. The system includes a passive or active radio identification device at each joint in the pipe or casing string. The devices are preferably sealed within the resilient seal positioned between each pipe or casing joint. A pipeline tool includes a radio transmitter and receiver, with the transmitter transmitting on a frequency selected for resonating the identification devices. The resonant response of each device is detected by a receiver in the pipeline tool, with the response transmitted to the surface via the wireline to which the tool is connected. Alternatively, the tool may include storage information means until the tool can be recovered from the well or pipe. An information storage and retrieval system includes information on the location of each of the identification devices in the well or pipe, e. g., length or depth, pipe or casing diameter, previously logged geological characteristics and stratum at each identification device location, etc.  The system may count each device as the tool passes through the pipe in order to determine the location of the tool at any point. Alternatively, each identification device may provide a distinct signal, with the tool transmitting the signal to the surface (or storing the signal for later retrieval) where the system correlates the signal with previously logged information for that specific location.

Abstract: A pull-type implement has operating components that are driven by a mechanical drive line on the tongue of the implement. An upper gear box is fixed to the front end of the tongue and a lower gear box swivels relative to the upper gear box about an upright axis passing through the two gear boxes. A hitch that establishes a draft connection between the tongue and the draw bar of a towing tractor has a fore-and-aft receiver that extends beneath the lower gear box and has a lower pivotal connection with the tongue at that location. A mast fixed to and projecting upwardly from the receiver has an upper pivotal connection with the tongue at a location above the upper gear box. The receiver has a forwardly facing socket that loosely receives the draw bar to permit the draw bar to swing up and down to a limited extent about a transverse axis and rotate side-to-side to a limited extent about a fore-and-aft axis when the draw bar is retained within the socket by a locking pin. One embodiment isolates both gear boxes from all draft loads, while a second, pull-through embodiment places a limited amount of draft loading on the lower gear box.
