Abstract: A toy play set contains a set of playing cards used to play at least one predetermined card game. The toy play set includes a generally elongated body having a closed configuration in which ends and a side wall generally surround a hollow interior and an open configuration in which the hollow interior is at least partially accessible. The cards are identically shaped and sized and sufficiently small to be completely stored within the body in its closed configuration. The body includes an internal spindle, and each of the cards has an opening allowing it to be mounted on the spindle.

Abstract: A toy play set for use in a vehicle having a beverage cup holder includes a generally elongated body. At least a first longitudinal end is sized and shaped to fit at least partially into the cup holder sufficiently for the cup holder to support the body in a generally upright orientation when the body has in a closed configuration. The body has an open configuration in which a hollow interior is at least partially accessible through at least one opening in a side wall. A plurality of movable components is stored in storage positions within the hollow interior in the closed configuration of the body. At least two of the plurality of movable components are removable from the storage position and are repositionable in the open configuration of the body into at least one play position different from the storage position of the at least two movable components.

Abstract: A rotatable drilling shoe attachable to a section of casing that allows for drilling and casing of a well bore in a single trip. The drilling shoe includes a fixed section and a rotatable section that has a drillable bit attached thereto. The drilling shoe further includes a mechanism for inhibiting rotation of the rotatable section after the casing is cemented into place so that the drillable bit can be drilled out by a subsequent drilling operation.

Abstract: A portable digital audio device sized and shaped for handheld operation. The device includes a digital music production system for mixing and editing audio content acquired by the device. A mixing system is configured to audibly combine two or more audio clips that have been acquired by the device. An editing system is configured to alter an acoustic attribute of an audio clip that has been acquired by the device. The device also may include a portable power supply configured to provide power to the device. A housing at least partially encloses the mixing system, editing system, and power supply.

Abstract: A digital audio device. According to one aspect of the invention, the device includes a memory and an analog input system configured to record analog audio signals to the memory as digital audio data. The device further includes a digital input configured to download digital audio data to the memory, as well as an analog output system configured to generate analog playback signals decoded from digital audio data stored in the memory. Furthermore, the device includes a digital output configured to upload digital audio data from the memory.

Abstract: A pipe supporting element is releasably mounted on a top rim of a form board used to contain and support concrete during a drying and set up stage of a concrete pouring operation. The pipe supporting element supports a pipe away from the form board so concrete can ompletely surround the pipe whereby the pipe will be completely embedded in the hardened concrete. The pipe support element is monolithic and includes a rectangular base attached to the form board by a fastener, such as a nail, and a C-shaped section which abuttingly engages the pipe. A strap, such as a wire, is wound around the pipe and around the nail to further attach the pipe to the pipe supporting element. The pipe supporting element can be removed from the form board for re-use.
