Abstract: A portable display frame includes a support frame and improved telescoping support bars. Each of the improved telescoping support bars includes a pass-through engaging slot on a first telescoping support bar section and an easily replaceable attachment projection member on a last telescoping support bar section. Known support bars require flexing the support bar to pass a closed end engaging slot on the first telescoping support bar section past a middle engaging hub, often resulting in damage to the telescoping support bar. The pass-through engaging slot of the present invention passes over the middle engaging hub without requiring flexing. Further, attachment projections on known support bars have broken and required time consuming repair or replacement of the support bar, often at an inconvenient time and location. The replaceable attachment projection member allows simple and easy repair when the attachment projections break.

Abstract: A slurry is used to secure a metallic casting core to a ceramic casting core. The slurry may be introduced between the metallic and ceramic casting cores and hardened. The slurry may comprise zircon and aqueous colloidal silica.

Abstract: An improved device for testing electrical circuit tracings on a printed circuit board is provided. The device includes a first plate, a second plate and connecting elements for connecting the first and second plates to one another, such that one or both of the plates can be moved relative to one another such that one or both of the plates can be moved relative to the other between a distal position wherein the plates are distal to one another and a proximal plate position wherein the plates are proximal to one another. The device further includes retaining device, which preferably is a pull-out tray, for retaining a printed circuit board between and substantially parallel to the first and second plates and a plurality of test probes disposed either above the retaining device and/or below the retaining device. The test probes are disposed so as to contact a trace on a circuit board being tested when that circuit board is disposed on the retaining device and when the plates are in the proximal plate position.

Abstract: A top for attachment to the frame of a boat is comprised of at least one panel member having a plurality of T-tracks arranged in spaced apart generally rectangular orientation. At least one body member is adapted to slide along each T-track and has a brake for inhibition of the sliding action. An adapter clip is attached to each body member for removable attachment of the top to the frame and additional adapter clips can be attached directly to the top for further attachment of the top to the frame.

Abstract: The flyer of the present invention comprises an upper main disk and a lower ring made from lightweight sheet material. The upper main disk and lower ring connect via an attachment element. Design, construction and assembly of the flyer of the present invention produce a stable flyer; when thrown flat, the flyer flies flat. Design, construction and assembly reduce or eliminate veering, an inherent characteristic of other common flyers. Distinguishing flight features of the flyer of the present invention arise where the design and construction of the flyer include a main disk and a lower ring separated by the attachment element, usually cut from the upper main disk and lower ring. Action between air and the upper main disk, lower ring and attachment means produce desirable flight features.

Abstract: A fish hook lure and leader carrier is formed from plastic. It has a basic configuration having a tubular structure with two caps, one on each end. The interior of the tubular structure houses the hooks and/or lures in the interior cavities. The leader extends through slots in the interior cavity and wraps around the outside of the tubular structure. When the two caps are snapped onto the ends the leader is held firmly in place. The interior cavity may contain a septum separating it into two cavities. These cavities may have end walls that occlude half the opening at each end of the tubular structure. The end walls are not opposite providing access to the two cavities.
