Abstract:
A twin wire welding apparatus including a first contact tube for guiding a first consumable electrode toward a weld puddle and transferring welding current to the first consumable electrode, a second contact tube for guiding a second consumable electrode toward said weld puddle and transferring welding current to the second consumable electrode, and a single power source connected to said first and second contact tubes for providing the same potential to said two consumable electrodes, and a method for operating such an apparatus.
Abstract:
A device for dispensing products senses when the respective products are accessed. A signal indicative of day and time of access can be transmitted to a remote monitoring station. Received signals can be compared to a pre-established schedule.
Abstract:
An improved tool for pulling off a rotor of a motor from a shaft or a fan from a shaft, which improved tool is provided with hooked arms that are releasably but securely held at one end in the housing, without the use of retaining clips, so that the arms do not fall off during use or become lost, and so that they do not interfere with the use of the tool when using the securing bolts for pulling off a rotor. The housing of the improved tool of the invention is circular in shape, and in a first version, is provided with a plurality of equally-spaced holes about its circumference, which holes received the hooked ends of the hooked arms, so that various configurations of hooked arms may be provided to best suit the configuration of vanes and type of fan being pulled off a shaft. In another version, instead of the plurality of equally-spaced holes for holding the hooked ends of the hooked arms, an annular groove is provided on the upper, horizontal surface of the lower circular cross-sectioned section of the housing, which annular groove is preferably continuous for 360 degrees about the upper, horizontal surface of the lower circular cross-sectioned section of the housing, whereby there is provided substantially an infinite spacing capability to the hooked ends of the hooked arms.
Abstract:
A system comprising a stanchion, the stanchion including a pole and a base supporting the pole. A cover adapted to display visible indicia, the cover defining an opening and a discontinuity extending from an exterior boundary of the cover to an interior boundary of the cover, the interior boundary bounding the opening. The discontinuity permits the pole to be positioned within the opening.
Abstract:
Methods, particles and devices are disclosed which are suitable for food-grade oil filtration. Disclosed particles may comprise an inert porous inner particle and at least a partial coating on the inner particle that comprises a polymer comprising at least one amine, amino or imine group.
Abstract:
The invention relates to two products, each of which can be designed to provide either permanent or semi-permanent hair hold. A first product includes two formulations applied to the hair in two separate steps, while a second product includes a single formulation applied to the hair in one step.
Abstract:
An improved tool for pulling off a rotor of a motor from a shaft or a fan from a shaft, which improved tool is provided with hooked arms that are releasably but securely held at one end in the housing, without the use of retaining clips, so that the arms do not fall off during use or become lost, and so that they do not interfere with the use of the tool when using the securing bolts for pulling off a rotor. The hooked arms of the invention are also hexagonal shaped, and securing bolts are provided with hexagonal-shaped recesses in their heads, so that the hooked arms may themselves be used for rotating the securing bolts when pulling off a rotor of a motor from a shaft. In addition, the housing of the improved tool of the invention is circular in shape, and is provided with a plurality of equally-spaced holes about its circumference, which holes received the hooked ends of the hooked arms, so that various configurations of hooked arms may be provided to best suit the configuration of vanes and type of fan being pulled off a shaft. To ensure that the each hooked arm is releasably retained in a respective hole of the housing, the end of the arm is provided with a hook defined by a straight piece extending at an acute angle with respect with the main, elongated body of the arm.

Abstract:
A method of optimising real cellular, wireless communication networks comprising the steps of providing location-referenced values of subscriber traffic for area elements; transmitting a reference signal of constant transmission power; providing a cell-referenced value of the power received from the reference signal; providing a model of the communication network having an original model network configuration, and iteratively optimising the model network configuration by accumulating and weighting the subscriber traffic values of the area elements and by locally adjusting the model network configuration, to provide an optimised model network configuration.
