Abstract: Device (10) for guiding a user to mark a core sample (12) carried by a core tube (14), the device (10) including: a housing (20) mountable relative to the core sample (12) or the core tube (14) and having a marking guide (22) configured to be arranged adjacent the core sample (12) to guide marking; a communications module (26) operable to communicate with the downhole tool (16) to receive data; a user interface (28) operable to convey perceptible feedback to the user; and a processor (30) and associated memory (32). The processor (30) is configured to store data in the memory (32) and determine a marking position based on the data, and operate the user interface (28) to direct the user to cause relative rotation of the marking guide (22) and the core sample (12) so that the marking guide (22) is aligned with the marking position, allowing the user to use the marking guide (22) to mark the core sample (12) at the marking position.

Abstract: An air blowing apparatus having an auxiliary housing and auxiliary air flow output that can be selectively engaged and disengaged is described herein. In an embodiment of the disclosure, the auxiliary housing can comprise an auxiliary fan to generate a second high speed air flow to supplement a high volume air flow of a primary housing. When baffled, the auxiliary fan is isolated from air intake and can be driven with little power consumption. An air blowing apparatus can be a backpack-style apparatus or hand-held air blowing apparatus. As examples, one airflow can have a relatively high volumetric flowrate relative to another airflow, or can have a high air speed relative to another airflow, or can have a high energy relative to another airflow, and so forth.

Abstract: Providing a portable blending sleeve for a food processor can include forming one or more structures of the blending sleeve that enable coupling of the blending sleeve with the food processor; and forming one or more structures of the blending sleeve that enable the food processor to blend a set of ingredients inside the blending sleeve.
