A panoramic optical device includes a quadric reflector, a mirror, and a set of one or more optical elements. The quadric reflector has a conical shape, which tapers from a wide base to an apex. The apex includes an aperture. The mirror is positioned within the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror reflects environmental light that is reflected by the quadric reflector into the aperture or reflecting light emitting from the aperture onto the quadric reflector. The set of one or more optical elements are positioned at least partially within a volumetric region of the quadric reflector. The one or more optical elements focus light passing through the aperture.

A degradation pick of the type used in such fields as road milling, mining, and trenching to engage and degrade tough materials such as asphalt, concrete, and rock may comprise a body attached at one end to a substantially cylindrical shaft. A hardened tip may also be attached to the body opposite the shaft. The hardened tip may comprise an axis offset from a central axis of the shaft. Such a degradation pick may be secured to an exterior of a rotatable drum or continuous chain so as to be repeatedly brought into contact with a surface of a material to be degraded. The body may comprise a protruding spine adjacent the hardened tip and opposite a direction of travel of the hardened tip when transported by a rotating drum or continuous chain.

A reflector can have a conical shape. The shape can tapers from a wide base to an apex. The apex can include an aperture, a mirror, and a set of one or more optical elements. A mirror is location in a cavity and is positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror can reflect environmental light that is reflected by the reflector into the aperture or reflect light emitting from the aperture onto the reflector. Stray light reflected by the mirror is absorbed by the cavity walls. A set of one or more optical elements can be positioned at least partially within a volumetric region of the reflector. The one or more optical elements focus light passing through the aperture to an image sensor.

A quadric reflector can have an approximately conical shape. The shape can tapers from a wide base to an apex. The apex can include an aperture, a mirror, and a set of one or more optical elements. A mirror can be positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror can reflect environmental light that is reflected by the quadric reflector into the aperture or reflect light emitting from the aperture onto the quadric reflector. The overhang enclosure can have a substantially conical shape which eliminates secondary reflection resulting from the environmental light reaching the aperture twice. Using the overhang enclosure to absorb the secondary reflection eliminates or minimizes banding.

A magnetic display unit includes: a display layer; a magnetic layer located behind the display layer; and a quick-release mechanism including an activator, wherein the quick-release mechanism is adapted to increase the distance between the magnetic layer and the display layer such that, when activated by the activator, the quick-release mechanism causes any magnets located along the display layer to be released from the display layer.

In one aspect of the present invention, a pick assembly is configured that comprises a pick shank configured to be press fit directly within a bore of a block. The pick shank comprises an inside and outside surface. The pick comprises a pick head opposite the shank. The shank comprises at least one longitudinal recess extending towards the pick head along the shank from a distal end of the shank. The recess allows the shank to resiliently collapse upon insertion into the bore while maintaining a press fit between the bore and the shank.

In one aspect of the present invention, a tool assembly comprises a rotary portion and a stationary portion. The rotary portion comprises a bolster bonded to a diamond symmetric, substantially conically shaped tip. The stationary portion comprises a block mounted to a driving mechanism. A compressible element is disposed intermediate and in mechanical contact with both the rotary and stationary portions. The compressible element is compressed sufficiently to restrict free rotation during a degradation operation.

Manually rotatable tool

A degradation assembly comprises a rotary portion and a stationary portion. The rotary portion includes a cemented metal bolster bonded to a tip. The tip comprises a symmetric, substantially conically shaped tip formed of diamond and a cemented metal carbide substrate. The stationary portion comprises a holder configured to be coupled to a block mounted to a driving mechanism. A compressible element is disposed intermediate, or between, and in mechanical contact with both the rotary portion and the stationary portion.

In one aspect of the invention, a pick assembly comprises a pick shank press fitted within a bore of a pick holder. The pick comprises a pick head opposite the shank. The shank also comprises at least one longitudinal slot extending towards the pick head along the shank from a distal end of the shank. The slot allows the shank to resiliently collapse upon insertion into the bore while still allowing the shank to maintain a press fit while within the bore.

In one aspect of the present invention, a degradation assembly comprises a pressing seal element and a pressurized rigid element disposed intermediate a rotating component and a stationary component. The rotating component comprising an impact tip bonded to an end opposing the stationary component. The seal element may energize the rigid element against one of the components to form a slidable seal capable of holding lubricant within the assembly and keeping debris out while still rotating.

A degradation assembly comprises a rotary portion and a stationary portion. The rotary portion includes a cemented metal bolster bonded to a tip. The tip comprises a asymmetric, substantially conically shaped tip formed of diamond and a cemented metal carbide substrate. The stationary portion comprises a holder configured to be coupled to a block mounted to a driving mechanism. A compressible element is disposed between and in mechanical contact with both the rotary portion and the stationary portion.

In one aspect of the present invention, the present invention is a system for removing aggregate from a paved surface. The system includes a motorized vehicle with a degradation drum that is connected to the underside of the vehicle. The degradation drum is enclosed by a milling chamber. The milling chamber is defined by having a plurality of plates, including a moldboard positioned rearward of the milling drum. The moldboard comprises an end that is disposed opposite the underside. The end comprises a section that is proximate the milling drum.
