A hand layout tool, apparatus, and method directed toward skilled and industrial trades, or for use within other similar mechanical layout and user applications, is presented. The current invention allows the trades technician or user to quickly and accurately determine or otherwise identify the outer or inner centerline of a radial or cylindrical surface feature at a selected or desired angle. Alternately, the current invention can allow the user to quickly, easily, and accurately measure or otherwise determine the included angle between two imaginary planes: a first plane defined as being coincident with the central axis of the cylindrical or radial surface and a first point on an outer or inner cylindrical or radial surface and a second plane defined as being coincident with the central axis of the cylindrical or radial surface and a second point on an outer or inner cylindrical or radial surface.

A tool for confirming the connection status of a fluid line to a quick-connect fluid coupling assembly includes a hub portion configured to interface with an outer portion of the fluid line, a finger coupled to the hub portion, a handle portion, a spring portion coupled to the hub portion and to the handle portion, and an indicating means. When the tool is placed in contact with the fluid line, a biasing force is applied to the tool in an axial direction, and a torque is applied to the handle portion to rotate the handle portion by a predetermined amount about the longitudinal axis of the fluid line, the finger cooperates with the retaining clip to produce a reaction torque to activate the indicating means when the fluid line is properly connected to the fluid coupling assembly.

Systems and methods for using high-impact fasteners to couple components of a solar power system together to prevent these components from any movement or slippage relative to each other. A strap may be secured over a top surface of the high-impact fasteners and around the components to prevent a disengagement of the high-impact fastener from the components and a separation of the components.

The present disclosure is directed to an apparatus for use with an adjustable wrench to limit the displacement of a broken portion of the adjustable wrench relative to the remaining parts of the adjustable wrench when the wrench fractures.

A heating system for a vehicle includes a low-temperature circuit and a high-temperature circuit which can be operated independently of each other and in which a low-temperature cooler or a high-temperature cooler is arranged. The two cooling circuits are coupled to each other via two coupling points for the exchange of coolant, and have a common conduit section, which extends between the two coupling points and on which a heat exchanger is arranged for heating the passenger compartment. A respective heat exchanger is arranged in the two cooling circuits, namely a low-temperature heat exchanger or a high-temperature heat exchanger for receiving waste heat from a respective vehicle component. The cooling circuits can be switched between a cooling operation and a heating operation.

A frozen desert holder holds flat for carrying in a purse or bag, and includes two opposing flaps which fold out above a handle portion. The handle portion includes a vertical passage for an ice cream stick, and the flaps catch drips which otherwise would fall onto a consumer's hand. The holder may be made from an absorbent biodegradable material having a water impermeable material backing.
