  • Patent number: 8562310
    Abstract: A pumping apparatus for pumping a liquid from a source to a target including a motor and pump driven by the motor. Sacrificial zinc components are utilized to minimize corrosion due to chlorine vapors. Measures to ensure that liquid is pumped in only one direction include the use of a full wave rectifier and/or a spacer incorporated with a swivel platform to limits the range of the angle between the motor shaft and the pump piston. To minimize the risk of rupturing the pump, the pump piston includes a relieved portion in fluid communication with a transverse bore of the pump housing when the piston is axially inserted within the pump housing in its full forward position. To prevent overheating and damage to the pump components, the pumping apparatus makes use of a positive temperature coefficient (PTC) resistor interposed between the motor and a current source.

  • Patent number: 8477992
    Abstract: The present subject matter relates to controlling of mail processing equipment. More specifically, the present subject matter allows for unique recognition of a printed document from all other similar documents, without the inclusion of additional purposeful identifying marks, data or barcodes. A document processing system, such as an inserter, printer, postage meter, sorter or other document processing system is controlled based on document identification which does not depend on unique identifiers. Similarly if a document is identified with a unique identifying mark on the first page, the present subject matter allows for identification of each subsequent page in the document without requiring identifying marks on each page. The identification data is then used to control the processing of the printed document based upon the recognition and enables the performance of quality checks.

  • Publication number: 20110319237
    Abstract: An apparatus for performing abdominal and squat exercises is provided with a frame having a support member, a first end and a second end that operate to provide horizontal stabilization, and at least two leg securing bars extending substantially transversely from the frame of the apparatus. A first leg securing bar may be disposed at a first location along the frame, and a second leg securing bar may be disposed at a second location along the frame such that the arrangement of the leg securing bars in the first and second locations permits the apparatus to operate as an exercise device for abdominal and squat exercises. A user of the apparatus may position one or more legs in between the leg securing bars and perform abdominal and squat exercises without having to readjust the leg securing bars and without having to move one or more feet thereof in between routines.
