Abstract: A router depth adjustment device includes a shaft with a first and a second end, a handle disposed on the first end of the shaft, for rotating the shaft, and a mechanical connection disposed on the second end. The mechanical connection is configured to couple with a corresponding mechanical connection on a depth adjustment shaft of a router. A depth adjustment indexing system includes an adjustment knob slidably mounted on the shaft and an indexer pivotally mounted to the adjustment knob. The adjustment knob and the indexer are capable of pivoting independently and pivoting simultaneously. The adjustment knob is configured such that rotation of the adjustment knob rotates the shaft.

Abstract: The present invention is directed to a detachable handle assembly for providing a mechanical device capable of utilization in securing and un-securing a work attachment, such as a blade or bit, to a hand-tool. The assembly includes a body portion for grasping, when implemented as an auxiliary handle for a hand-tool such as a power tool or a pneumatic tool.

Abstract: The present invention is a method and apparatus for monitoring the condition of a cable in a human power amplifying lift system. The method and apparatus employ a cable slack sensor and a cable end sensor to override and prevent the lift from continuing to unwind the lift cable when slack or and end of travel limit has been reached.

Abstract: This crane control apparatus and method with swing control and variable impedance is intended for use with overhead cranes where a line suspended from a moveable hoist suspends a load. It is responsive to operator force applied to the load and uses a control strategy based on estimating the force applied by the operator to the load and, subject to a variable desired load impedance, reacting in response to this estimate. The human pushing force on the load is not measured directly, but is estimated from measurement of the angle of deflection of the line suspending the load and measurement of hoist position.

Abstract: A fraud detection and security system for financial institutions utilizes a secure database of information relating to financial transactions of non-account holders who present checks and other instruments for payment. The system collects and tracks the frequency of particular aspects of the subject's behavior, and flags deviations from such norms for the purpose of indicating that fraudulent or criminal behavior may be occurring. At such time, the teller or other employee with whom the subject is dealing may stop the transaction, to the benefit of the financial institution and account holder. The system also allows for law enforcement to detect related transactions, or a string of criminal activity from the same perpetrator. In the preferred mode, the system includes a teller collecting information from the non-account holder, including name, date of birth, address, gender, driver's license number, social security number, and/or telephone number.

Abstract: This pendant responsive crane control system has a sensor pendulum arranged above a hoist for the crane and a load sensor for determining the load lifted by the hoist. The sensor pendulum serves as a swinging link between the hoist and a crane drive for moving the hoist. Lateral movement sensors generate signals in response to lateral movement of the sensor pendulum. A crane control means directs lateral movement of the crane drive in response to the signals generated by these sensors. The load sensor used is preferably a load cell or strain gauge incorporated into the sensor pendulum.

Abstract: A beam extruded of aluminum alloy for use in cranes and conveyors is formed with a channel having runs that straddle an open bottom and are strengthened by pin receivers formed in C-shapes with material integrally extruded under the runs. An upper region of the channel is formed with upright parallel fins that serve as a mounting element. T-shaped strengthening upper beam elements can be secured to the channel by sliding them between the parallel fins where they are held in place by fasteners. The upright fins also accommodate a variety of mounting arrangements.

Abstract: This invention turns pages of music using transparent fingers that are controlled by a hand or foot pedal, which is operated by the musician. The pages are turned by a self-contained electric motor that may be powered by a lightweight battery. The device is contained in an attractive case that doubles as a music holder. When desired, the pages may be reset to any point in the music by using a reset knob and the page turner will continue to turn the pages upon command from the musician.

Abstract: The present disclosure relates to a dust-collection system for use with a power tool such as a router. The system includes a router sub-base adapted for connection to a router. The router sub-base defines an opening configured to receive a cutting tool of the router. The system also includes lower and upper vacuum flowpaths. The lower vacuum flowpath is arranged and configured to evacuate dust from beneath the opening of the router sub-base. The upper vacuum flowpath is arranged and configured to evacuate dust from within the opening of the router sub-base.

Abstract: An articulating suspension for the bridge of an overhead bridge crane allows the bridge to be skewed from perpendicular to the parallel runs that support the bridge. The runs are allowed to pivot toward each other on pivot axes above and parallel with each run. End trucks that support end regions of the bridge from each run are interconnected with the bridge via suspension hangers. These are suspended on end truck pivots that are parallel with the runs and include thrust bearings that allow the bridge to skew. The bridge is suspended from the hangers on a pivot axis above and parallel with the bridge. The arrangement allows the necessary freedom of movements for skewing the bridge without making the crane wobbly or unstable. The arrangement of pivot pins and thrust bearings also is rugged and durable and requires little maintenance.

Abstract: An overhead bridge crane truss having a channel connected to a support beam by vertical connectors is improved in strength by adding wide braces at end regions of the truss, without significantly increasing truss weight or cost. The wide braces are rectangular box beams welded around their upper and lower peripheries respectively to the bottom of the support beam and the top of the channel.

Abstract: A beam for a bridge crane or conveyor system is extruded from an aluminum alloy in a configuration that disposes thickened regions at four corners of the beam. One pair of these is along opposite edges of a top flange, and another pair is at opposite lower corners of a bottom channel. The thickened regions are formed with alignment pin dowel grooves that can receive dowel pins for aligning butt joints between beams. The thickened regions also contribute to the strength-to-weight ratio of the beam.
