Abstract: A guide wheel assembly adapted to retrofit a shopping cart having a guide wheel capable of only rotating in the intended direction of travel of the shopping cart and a flexible one piece mechanism possessing strong material memory such that constant contact between the guide wheel and a traveling surface is maintained. The guide wheel assembly is configured to allow the nesting of multiple carts.

Abstract: A golf teeing device includes a one-piece singulation arm having a ball-receiving region that is connected to a ball-seating region by a ramp region. The unitary singulation arm has a raised rest position and a lowered delivery position. The configuration of the ramp region channels a golf ball to the ball-seating region when the singulation arm is in its delivery position. The configuration of the ball-seating region inhibits horizontal movement of the ball in any direction when the ball reaches this region. In one embodiment, all three regions of the singulation arm have dimensions that are consistent with the channel of the ramp region. A ball-striking mechanism within a supply path to the singulation arm is activated to provide dislodging forces to at least two balls, thereby ensuring a consistent flow of balls to the singulation arm.

Abstract: An apparatus for switching a write-protect tab of a computer disk includes a supply hopper for storing a plurality of disks and includes a mechanism for delivering the disks in a one-by-one manner to a switching area. At the switching area, a tungsten carbide tip is caused to move vertically into contact with a major surface of the tab, and then horizontally to slide the tab into the desired position. The tungsten carbide tip includes teeth that are arranged in mirror-imaged first and second sets, so that the apparatus operates equally well in either switching direction. After the tab has been moved to the desired position, the disk is delivered to the disk-receiving hopper and elevated to accommodate delivery of the next disk.

Abstract: A method of loading disks includes first and second air-jet nozzles and a continuous flow of air. The first air jet nozzle is directed into the opening of the flexible bag to initiate opening the bag at a localized region. The continuous flow is designed to fully open the bag by taking advantage of the localized opening. The second air jet nozzle improves the reliability of the opening process by striking a surface of the flexible bag to overcome the continuous flow. Impinging the bag in this manner tends to remove any wrinkles at the opening, so that when the second jet is terminated the continuous flow fully opens the bag. Preferably, the second air jet flow is ionized, thereby neutralizing any static charge that is stored by the bag. Typically, the first and second air jet flows do not overlap in time.

Abstract: An apparatus for sequentially releasing computer disks from a stack includes a hopper and a pusher member for sliding a lowermost disk from beneath the stack. A next lowermost disk is held at an angle to the lowermost disk to limit contact of the disks to rearward disk edges, so that sliding contact is minimized. The front edge of the next lowermost disk is supported by a sloped surface to achieve the desired angle and to allow gravitational feed of the disks as the pusher plate is unloaded by a forward disk delivery and a rearward return. At the rearward end of the next lowest disk, an inwardly sloped surface provides space for the disk to slide down the outwardly sloped surface into the loaded position. Preferably, the hopper is one of a number of hoppers used in collating computer disks.

Abstract: An apparatus and system for sequentially releasing floppy disks includes a hopper for holding the stack of the disks and a mechanism for sliding the lowermost disk in the stack from beneath the remainder of the stack. A plunger device enters the area between the lowermost disk and a next lowest disk to provide some separation at an area of concern, while leaving sufficient contact between the two disks to ensure that the stack and a load member atop the stack provide the gravitational force necessary to properly position the lowermost disk for release. In a preferred embodiment, the stacks of disks are floppy disks and the plunger device is aligned to provide separation at write-protect notches of the disk. The plunger device may be a fluid-actuated device.
