Abstract: This invention is a manually operated tube bending machine with a power drive mechanism that is adjustably set to a desired bend speed. The bending machine includes a bending die, a counter die and a rotating hook die to form a desired bend into a tube or pipe. The tube bender includes a drive wheel with ratchet teeth around its perimeter. A drive pin grips one of the ratchet teeth. The drive pin is secured to a lever and torque bar. During each bending stroke, the lever and torque bar incrementally rotate the drive wheel a desired amount. The rotation of the drive wheel and hook die draw the tube through the bending and counter dies to bend the tube. An anti-spring back mechanism holds the position of the drive wheel while the power drive mechanism is advanced to grip the next ratchet tooth of the drive wheel.

Abstract: A dock leveler with a deck and an extendable lip that hangs pendant when the deck is in a stored position. A lip extension mechanism engages when the deck is raised to a raised or cocked position. As the deck is lowered to an intermediate transition position, the extension mechanism extends the lip to a fully extended position. At the transition position, the lip extension mechanism automatically disengages and a lip locking mechanism automatically and simultaneously locks and holds the lip in its fully extended position. When the deck is further lowered so that the lip comes to rest on a truck trailer, the locking mechanism automatically released or unlocked. The lip returns to its pendant position when the deck is raised from the truck bed. After the truck pulls away from the dock, the deck is lowered to its stored position.

Abstract: The invention is a multi-mode hammering machine that operates in a rigid mode, a flexible power hammer mode and a machine press mode to contour, shape and form sheet metal products. In all three modes, a ram is linearly stroked toward and away from a fixed die by a common ram drive assembly that includes a lever drive assembly and a reciprocating lever. The lever drive assembly moves in a rigid non-flexing manner. The reciprocating lever includes a rigid mode and a flexible mode. A conversion pin is used to engage one and simultaneously disengage the other. The lever drive assembly includes a control link that interfaces with a stroke adjustment mechanism. The gap adjustment mechanism is located at the fulcrum of the reciprocating lever. Both stroke length and gap are adjusted independently during the operation while the ram is cycling.

Abstract: The invention is a rotary draw bending machine and process for bending materials such as tubes or pipes into precise bends. A spindle holds a bending die, and a radial arm holds a counter-die. The spindle and arm are simultaneously rotated in opposite directions by a dual hydraulic drive controlled by an electro-hydraulic control system with foot pedal controls. The bend angle is preset by a protractor-like dial and limit switch mechanism. The radial arm has a slide track to align the counter-die with the bending die. The ratchet mechanism has teeth to allow incremental advancement of the counter-die when aligning it with its bending die to accurately set the gap between the dies. The machine is used with a wide variety of dies to bend a wide variety of workpiece diameters. The ratchet mechanism preferably includes a fine tuning device to provide an infinite range of alignment positions.

Abstract: A computer input device on a glove includes fittings for a user's fingers and adjustable straps for fastening to a user's wrist. A tracking device for controlling cursor movement on a video display is affixed to the glove for positioning next to the end of one of the user's fingers. Pressure plates for controlling the various right and left mouse “clicking” functions are affixed to the glove for positioning next to the ends of the other of the user's fingers. Scrolling/paging buttons are located on the side of the fitting fitted to the index finger for pressing by the thumb. A transmitter is affixed to the glove for receiving signals from the tracking device, the pressure plates and the scrolling/paging buttons, and transmitting those signals to a computer for controlling cursor movement in the x-y plane on a video display and for controlling the various mouse “clicking” controls, which implement the “select” function, the “drag” function, the “scroll” function, the “page” function, and so forth.

Abstract: The present invention relates to a composite masonry edging or stepping block used with other like-shaped blocks to form a continuous interconnected edging pattern or stepping path that accommodates straight sections and tight bends in the pattern or path. Each block has a series of six adjoining projections around a major portion of its perimeter, and a pair of adjoining recesses along a minor portion of its perimeter. Two adjoining projections form a multi-wave protrusion. Several combinations of two adjoining projections can be used to form a number of multi-wave protrusion. Each protrusion has the same size and shape but extends in a different angular direction. The two recesses form a multi-wave indentation. The multi-wave indentation flushly receives one of the multi-wave protrusions of an adjacent block to achieve an interlocking connection in either straight or angled alignments. The structure of each block forms a flower-like pattern.

Abstract: This invention relates to a method and apparatus for administering prescribed medication to a patient. The prescribed medication administration system and apparatus dispense prescribed medication, verify the medication is given to a correct patient by an authorized healthcare worker and tracks and records the administration of the medication. The system utilizes a workstation connected to a database containing prescribed medication dose information for various patients. A healthcare worker uses the workstation to manually or automatically dispenses the medication the portable container. An information device is secured to the portable container during transport and administration of the medication to the intended patient. The information device prevents access to the medication or warns the healthcare worker of a potential error if the medication is delivered to the wrong patient or administered by an unauthorized healthcare worker.

Abstract: The present invention relates to a non-invasive penile erection device having a constrictor ring designed to fit against the base of a male genital or penis, and a diaphragm seal that forms a substantially air tight seal against the constrictor ring. The constrictor ring is designed to comfortably and securely fit the base of the penis. The substantially air tight seal enables the pump to produce vacuum pressures of over 17 inches of mercury. The placement of the constrictor ring on the base of the penis and the greater vacuum pressure achieved by the device tend to draw the root of the penis into the constrictor ring so that a more natural erection is achieved and maintained after the vacuum tube is removed. The erection device can be easily provided as a kit containing a rigid vacuum tube, a hand or power operated pump, and several diaphragm seals and constrictor rings of various sizes to achieve a custom fit and optimum results.

Abstract: A detachable fishing rod and reel holder, for use by a fisherman in a sitting position is disclosed. The holder comprises a concave, convex frame attached to the fisherman's leg with the concave surface bearing against the fisherman's shin whereby the force applied to the line from a fish strike is transmitted to the users leg thereby alerting him to the fish strike. The hook may be set by the simple movement of the fisherman's leg, by rotating the leg about the hip joint, or the knee joint as a pivot point.

Abstract: The present invention relates to a non-invasive penile erection device having a constrictor ring designed to fit against the base of a male genital or penis, and a diaphragm seal that forms a substantially air tight seal against the constrictor ring. The constrictor ring is designed to comfortably and securely fit the base of the penis. The substantially air tight seal enables the pump to produce vacuum pressures of over 17 inches of mercury. The diaphragm seal is designed to collapse around the constrictor ring and remain on during sexual activity. The diaphragm seal cooperates with the constrictor ring to apply pressure to the surface of the penis. The placement of the constrictor ring on the base of the penis and the greater vacuum pressure achieved by the device tend to draw the root or "oz" of the penis into the constrictor ring so that a more natural erection is achieved and maintained after the vacuum tube is removed.

Abstract: The present invention relates to a low profile monolithic crystal strip filter and filter package. The filter includes an AT-cut rectangular strip of quartz crystal. The filter further includes input, output and ground electrodes which are formed in a symmetrical pattern on the strip. Each electrode is connected to its respective mounting or ground contact by a flag. The electrodes, contacts and flags have a predetermined size and shape, and are arranged in a predetermined configuration on the crystal strip to minimize spurious responses and insertion losses. The crystal strip is mounted to an HC-45 or HC-49 base to minimize production costs. The output signal of the filter has a center frequency of about 4 to 500 MHz, a 3 dB bandwidth of about 3 to 250 kHz, an ultimate of better than 60 dB, standard insertion losses for the number of poles in the filter and commercially acceptable spurious responses.
