A chalk reel includes a housing defining a chalk chamber and an opening from the chalk chamber; a spool positioned within the chalk chamber; and a line wound on the spool and extending through the opening, the line having a width of dimension X. The spool comprises an axial hub and a sidewall. The sidewall comprises a plurality of apertures extending through the sidewall from a first face distal from the axial hub to a second face proximal to the axial hub. Each of the plurality of apertures having a maximum width of dimension Y. The dimension Y is sized so that no loops of the line may fit through each of the plurality of apertures.

Jam resistant chalk reel

Certain embodiments of a folding knife are disclosed. In one embodiment, an example knife may include a handle and a blade carrier. The blade carrier may be rotatable about the handle and may include a left and a right cap. A blade may be removably disposed within the blade carrier. The knife may further include a blade release mechanism. In one embodiment, the blade release mechanism may include a compression spring and a lift bar. In another embodiment, the blade release mechanism may further include a wheel. In yet another embodiment, the blade release mechanism may include a leaf spring and a slide bar. When the blade carrier is rotated such that the knife is not in a cutting position, at least a portion of the blade release mechanism is exposed. When the blade release mechanism is activated, the blade may be removed from within the blade carrier.

Folding knife with selectively hidden blade release

A chalk reel includes a housing defining a chalk chamber and an opening from the chalk chamber; a spool positioned within the chalk chamber; and a line wound on the spool and extending through the opening, the line having a width of dimension X. The spool comprises an axial hub and a sidewall. The sidewall comprises a plurality of apertures extending through the sidewall from a first face distal from the axial hub to a second face proximal to the axial hub. Each of the plurality of apertures having a maximum width of dimension Y. The dimension Y is less than or approximately equal to twice the dimension X.

A chalk line is disclosed herein. The chalk line may include a housing, a track, and a door. The housing may define a chalk chamber and an opening in communication with the chalk chamber. The track may be disposed adjacent the opening and may include a curved section. The door may be movable between a closed position preventing access to the chalk chamber through the opening and an open position allowing access to the chalk chamber through the opening, and the door may include one or more door segments pivotably connected to one another by one or more hinges.

Chalk line

A chalk reel has a housing defining a chalk chamber and an opening for accessing the chamber. A door is movable between an open position for allowing access through the opening to the chalk chamber and a closed position preventing access to the chamber. A lock assembly is provided on the door and is movable with the door. The lock assembly rotates relative to the door between a locked position and an unlocked position and reciprocates to secure and release a lock member.

Chalk reel

A torch assembly adapted to be attached to an associated fuel supply, the torch assembly has a housing, a fuel line at least partially contained within the housing, a burn tube extending from the housing and adapted to receive fuel from the fuel line, an attachment member operatively connected to the housing for connecting the torch assembly to the associated fuel supply, the attachment member in fluid communication with the fuel line for delivering fuel from the associated fuel supply to the fuel line; a control apparatus having a trigger for actuating an on/off valve adapted to permit or stop flow through the fuel line, a regulator adapted to at least partially restrict flow in the fuel line, and a controller operatively connected to the regulator to adjust the position of the regulator to vary the flow of fuel through the fuel line.

Utility knife handle

Utility knife

A torch assembly having features enabling single handed operation. The torch assembly includes a flame control device that can be operated with a user's fingers while the user is holding the torch with the same hand. A controller apparatus of the torch assembly includes a trigger for actuating an on/off valve adapted to permit or stop flow through a fuel line, a regulator adapted to at least partially restrict flow in the fuel line and including a regulator valve, and a controller operatively connected to the regulator to adjust the position of the valve to vary the flow of fuel through the fuel line. The controller is interposed between the trigger and the regulator, and can include a rotatably mounted knob.

Pressure sensor methods and systems are disclosed. In general, two micromachined die and a diaphragm for a pressure sensor can be provided. The two micromachined die can be embedded in a glass adhesive on a surface of the diaphragm, such that the glass adhesive possesses a large size relative to the two micromachined die. The large size of the glass adhesive creates a large planar target for placement of the two micromachined die upon the diaphragm, thereby providing a size difference between the glass adhesive and the two micromachined die thereby creates an optimum strain transfer, while maintaining stability for the pressure sensor.

Pressure sensor with single deposit adhesive

Differential pressure sensor systems and methods are disclosed, including an absolute pressure sensor composed of a plurality of pressure sense die for detecting sensed media, wherein each of the pressure sense die possess a back side and a front side and are respectively associated with a plurality of varying pressures. The sensed media are applied only at the backside of the pressure sense die, thereby preventing wire bonds and active regions associated with the front side of the pressure sense die from exposure to sensed media and attack from acids and abrasive chemicals associated with the sensed media.

Differential pressure measurement using backside sensing and a single ASIC

Sensor systems and methods are disclosed, which generally incorporate isolation between the sensor's electronics and the sensed media. The sensor's electronic circuit can incorporate one or more application specific integrated circuit (ASIC) that processes and outputs the signal for both absolute and differential measurements. Such a sensor can be adapted for use in exhaust gas re-circulation (EGR) systems utilized with automotive gasoline engines. Such a sensor can also be utilized for measuring differential pressure across diesel particular filters and/or applications in which differential pressure is required for system control and/or monitoring purposes. The absolute pressure sensor disclosed herein can therefore sense the exhaust pressure on automotive engines and other mechanical and/or electromechanical devices and machines.

Exhaust back pressure sensor using absolute micromachined pressure sense die

A high pressure sensor is provided with a single-piece pressure port machined from stainless steel and has no internal gaskets or seals. A housing surrounds the pressure port along a portion of its axial length. The housing and pressure port have mating configurations that prevent axial rotation when the pressure port is inserted into the assembled position in the housing. A retaining ring locks the pressure port axially with respect to the housing and is fixed in place by a fixative, such as epoxy.
