  • Patent number: 9802686
    Abstract: The present application relates to an accessory paddle head for use with a spinnaker pole. The accessory paddle head is adapted to releasably connect to a spinnaker pole to provide a paddle system. The accessory paddle head surface optionally includes gripping members disposed on its surface for engaging with and detachably securing the spinnaker pole. The accessory paddle head is optionally formed of molded material.
    Type: Grant

  • Patent number: 6746018
    Abstract: A multiple shaft seal arrangement positioned between a shaft and an inside diameter surface of an aperture in a wall. The multiple shaft seal arrangement has a flinger attached to the shaft with a face seal mounted to the flinger. A double lip oil seal is mounted to the inside diameter of the aperture. The flinger is positioned such that the face seal is pressed against the double lip oil seal. Accordingly, rotation of the shaft causes rotation of the flinger and face seal. This centrifugally throws contaminants, such as particulate matter, away from the aperture. The void between the face seal and the inside diameter of the aperture is filled with grease or similar substance. The combination of these elements greatly prohibits debris, moisture, particulate matter or other environmental elements from passing from one side of the multiple shaft seal arrangement to the other.

  • Patent number: 6663313
    Abstract: A mounting system for a speed reducer having a housing with a rotatable input drive coupled with the housing and a gear train coupled with the input to drive an output. The mounting system has a cylinder having an inner and outer surface and two ends. The outer surface includes a portion adapted to couple with the drive train. The outer surface at both ends may have a threaded portion or another securement portion. The inner surface may be tapered from both the ends such that the tapers are substantially symmetrical about the cylinder. A bushing ring, with an internal diameter, may include threads to threadily connect with either threaded end of the output cylinder, or another type of securement may be used. A bushing, which includes a flange and a cylindrical portion, is adapted to couple with the bushing ring. The flange portion couples with the bushing ring on either side of the output cylinder.

  • Patent number: 5341595
    Abstract: An environmental day-lit chamber for plant growth analysis having therein a growth chamber with a perforated or slotted plant supporting floor for allowing air to be forced vertically through the plant space. The transparent and frameless exterior of the chamber shell allows equalized distribution of sunlight with minimal impedance into the growth chamber. A vertical surface at the rear of the plant growth chamber forms a return air plenum for ducting air through the growth chamber and back to an air conditioning compartment beneath the growth chamber for reconditioning the air. A gasketed door at the front of the chamber shell provides reach-in capacity for entry into the plant growth chamber and expedites the ability to sealing close the growth chamber upon completion of operations therein.
