A measurement apparatus includes a horizontal plate. The horizontal plate includes a first plate end, a second plate end disposed away from the first plate end in a longitudinal direction, a first plate surface extending between the first plate end and the second plate end, and a second plate surface extending between the first plate end and the second plate end. The second plate surface is disposed away from the first plate surface in a normal direction. A first support member extends from the first plate end longitudinally toward the second plate end and protrudes in a direction normally away from the second plate surface. A second support member extends from the first plate end longitudinally toward the second plate end and protrudes in a direction normally away from the second plate surface. A measurement bar contacts the first support member and the second support member.

Methods and devices for checking the geometry of an angle-of-attack sensor belonging to an aircraft are provided. The device includes one or more stages, a stage comprising a slot the geometric dimensions of which are specifically configured to accept a portion of the said angle-of-attack sensor. The device allows a visual inspection but can also be instrumented (photoelectric cell, laser, camera) in order to verify the geometry of the sensor in detail. Developments notably describe the use of signal indicators, motorized stages, one or more image sensors, specific materials, communications with computers, or placement by drone and/or robotic arm. Software aspects are described.

A brush gauge includes a stepped barb and an arcuate ledge. The stepped barb and the arcuate ledge partially define an aperture.

An electrofusion pipe measuring device, including a first section including a first edge and a second edge, a second section extending from the first section, the second section including a third edge arranged perpendicular to the first edge and a fourth edge, and a third section rotatably connected to one of the first section and the second section, the third section including a fifth edge and a sixth edge.

A modular nut cleaning plant comprises a nut sizer and a stick remover mounted to the nut sizer. A vacuum unit is mounted to the stick remover. A nut product stream will pass on the stick remover through the vacuum unit which will vacuum light debris from the nut product stream. The nut product stream moves on a chain on the stick remover. Large debris and sticks that do not fall through openings in the chain will pass into a debris conveyor. Nuts and debris that fall through the openings in the chain will be delivered to the nut sizer. The nut sizer will rotate and tumble nuts and debris in the nut product stream. Nuts of an undesirable size and debris will pass into a debris conveyor. Nuts of a desired size will pass through the nut sizer into a chute or other conveyance to be delivered to further nut processing apparatus.

A nut sizer includes a nut sizer frame and a rotatable nut sizer cage mounted therein. A motor is attached to the nut sizer frame at an intake end thereof. The motor will drive a drive sprocket which will in turn drive a reel sprocket that is connected to the rotatable sizer cage. A chain engages the drive sprocket and the reel sprocket. The sizer cage may be lifted from the nut sizer frame by removing the chain. The nut sizer cage is a sectioned sizer cage and includes a first sizer section and a second sizer section detachably connected thereto.

A nut processing apparatus includes a pair of side panels with a vacuum duct connected thereto. The nut processing apparatus which may be referred to as a vacuum unit is configured to be mounted directly to other nut processing equipment such as for example a stick remover. The vacuum unit includes a vacuum duct with an upper stationary portion and a lower pivotable portion.

A kit of wire gauge tools is provided. Each wire gauge tool is dimensioned and adapted to measure a diameter of wiring and associated insulation. Each wire gauge tool may be elongated with a thin profile, where both ends provide a different measuring slot. The present invention may include a case for housing the kit or plurality of wire gauge tools. Each wire gauge tool in the kit may be a different color for immediate identification of the diameters measurable with that specific tool.
