  • Patent number: 7874126
    Abstract: A service line distribution base (10) comprises a ground anchor (18) having an upstanding cruciform portion adapted to extend into the ground. A cabinet (20) suited to support a utility pole (14) extends upwardly from the ground anchor (18). The cabinet (20) defines and internal space for receiving buried wire conduits (28) incorporated to the cruciform ground anchor (18). The cruciform shape of the ground anchor (18) advantageously permits to incorporate a greater number of wire conduits (28) into the base of a utility pole as compared to conventional concrete bases.

  • Patent number: 7871356
    Abstract: An arm mechanism for an elliptical exerciser comprises a linkage having a first end pivotally mounted to a frame of the elliptical exerciser, and a second end receiving a reciprocating movement from a foot pedal of the elliptical exerciser. An arm member has a handling portion to be handled by a user of the elliptical exerciser, and a coupling portion to be coupled to the first end of the linkage. A coupling mechanism releasably couples the linkage to the arm member such that the linkage and the arm member rotate jointly about the frame upon the linkage receiving the reciprocating movement from the foot pedal in a coupled position of the coupling mechanism, and for decoupling the arm member from the linkage in a decoupled position of the coupling mechanism to prevent rotation of the arm member while the linkage rotates.

  • Patent number: 7872847
    Abstract: Protective equipment for safely discharging electrical potential comprises an interface (10, 50, 60) adapted to be in contact with a wearer. A conductive path in the interface contacts the wearer, the conductive path reaching a ground. A first circuit device (30) is provided in the conductive path. The first circuit device (30) has at least one variable resistance so as to oppose a first level of variable resistance to decrease a conductivity in the conductive path as a function of an increase in potential difference between the wearer and the ground, to allow static discharge through the protective equipment.

  • Patent number: 7866980
    Abstract: Dental implant drill holes and the shape of a dental implant superstructure are chosen by creating a computer model giving jawbone structural details, gum surface shape information and proposed teeth or dental prosthesis shape information. The computer model shows the bone structure, gum surface and teeth images properly referenced to one another so that implant drill hole positions can be selected taking into consideration proper positioning within the bone as well as proper positioning with respect to the dental prosthesis. Similarly, manufacture of the dental implant superstructures used for fixed dental prosthesis or overdentures can be designed based on knowledge of the actual implant positions referenced to an image of the gum surface and proposed dental prosthesis.

  • Patent number: 7867360
    Abstract: Polysulphide produced by oxidizing white liquor includes both active and inactive components. “Active” polysulphide is the only component that increases pulp yield. The amount of active polysulphide formed when manganese oxides are used as catalysts in the generating process is increased by adding a co-catalyst. Adding bismuth compounds and, in particular, bismuth oxide as a co-catalyst increases the total amount of polysulphide formed with all the manganese oxides and increases the amount of active polysulphide produced particularly when using the lower manganese oxides. The co-catalyst also increases the number of cycles in which the most active catalyst, manganese dioxide, can participate before losing efficiency. Other elements in the same group and adjacent groups in the periodic table are active but these other elements are more soluble than bismuth and are toxic.
