摘要： A safety device for use with a chain extending between a trailer and a tow vehicle. The device has a central sleeve that houses the chain. Two side sleeves extend parallel to the central sleeve and house an elastic cord. The elastic cord provides tension to the sleeve, allowing the chain to group or bunch up without tension. The allows a user to avoid having to manipulate the length of the chain in order to avoid chain drag from the chains being too long or chain bind from the chains being too short when the vehicle attempts to turn while towing the trailer. Typically trailers have a pair of safety chains extending from the trailer to the vehicle, thus two of the devices are preferably utilized.

摘要： The present invention relates to a polymer comprising repeating units consisting of a substituted pyrrole ring. In particular, the repeating units consist of substituted pyrrole containing polar groups capable of interacting with carbon allotropes such as carbon nanotubes, graphene or nanographites, in order to improve the chemical-physical characteristics of the allotropes mainly by increasing their dispersibility and stability in liquid media and in polymer matrices. The invention also relates to products of addition of these polymers with carbon allotropes in order to obtain easily dispersible macromolecules.

摘要： A grounding attachment for use with a CRS Roller. The grounding attachment has a body having two arms. Each arm is pivotally attached to the body. The arms are configured to be biased downward onto a conductor positioned on the CRS Roller. Preferably a torsion spring biases the arms downward such that a roller attached to each arm rests on a conductor positioned within the radius block. Energy is conducted from the conductor, through the roller and arm to a grounding lug that is configured for a lineworker to attach a ground to the grounding device to allow the energy to reach the earth.

摘要： What is disclosed is a self governing speed control device for controlling the rotation speed of a sprinkler turbine. The device has a housing that houses a viscous fluid. An axle extends into the housing and is configured to rotate in the housing. The axle is fixedly attached to a primary drum that rotates with the axle. One or more hinge pins extends from the primary drum. A brake shoe is positioned on the hinge pin. The hinge pin passes into a slot in an actuation drum configured to rotate on the axle. The brake shoe is configured to expand and contract based on the speed of rotation of the axle in relation to the speed of rotation of the actuation drum.

摘要： An improved luminaire configured to detect dawn and dusk and to turn on, dim and/or turn off in response to the ambient light level. The luminaire is configured to delay turning on, dimming, and/or turning off such that light emitted by the luminaire can be utilized by neighboring luminaires in calculating the ambient light level in determining if dawn, dusk, or other low light condition has begun or is ending. The luminaires further utilize a timer for measuring the ambient light so as to avoid momentary or brief ambient light changes caused by, for example, weather conditions or temporarily reflected light such as by a vehicle positioned proximate to on or more of the luminaires.

摘要： A sprinkler head for irrigation having a sprinkler body. The sprinkler body surrounds a fluid delivery tube. The sprinkler body includes an upper plate and a lower plate. A and exits out the fluid nozzle. A fluid distribution cage is positioned on the sprinkler body and around the fluid delivery tube. The fluid distribution cage has one or more arms connecting an upper plate and a lower plate. The lower plate is configured to direct fluid sprayed onto it from the fluid delivery tube. When fluid is sprayed on the lower plate the upper plate begins to nutate around the fluid delivery tube between the upper sprinkler body plate and lower sprinkler body plate. The upper and lower sprinkler body plates have races configured for receiving one or more resilient cushions positioned on the upper plate of the fluid distribution cage. The upper cage plate or the lower sprinkler body plate has one or more projections positioned such that the fluid distribution cage hangs at an angle to facilitate initiation of nutation of the fluid distribution cage.

摘要： A sprinkler head is disclosed having a fluid distribution cage configured to nutate between an upper sprinkler body plate and a lower sprinkler body plate. The sprinkler head has a projection to cause the fluid distribution cage to hang at a non-horizontal angle prior to initiation of nutation. The projection is configured to move or rotate away from the upper cage plate of the fluid distribution cage during nutation initiation. Preferably the projection is positioned on a gimbal ring that rotates in response to force asserted on the projection by the upper cage plate. Preferably the gimbal ring has two projections positioned on opposing sides of the axis of rotation of the gimbal ring.

摘要： A bagel cookware comprises a round bagel tray sized to hold about four bagels in a twelve-inch pot of boiling water. The bagel tray has about four vertical bagel support rods and a central socket comprising a cylindrical collar. This cylindrical collar has a pair of bosses to receive a hollow end of a lifting handle. When the handle is twisted the bosses engage a pair of L shaped retainer channels in a hollow mouth at the bottom of the handle. The handle also has a series of anti-floatation screens so the bagels cannot float while boiling. The chef can use the removable handle to place the cookware in boiling water, then pick up the cookware, tilt the cookware, and place it in an oven. Commercial embodiments could use robotics and hold dozens of bagels on an equivalent apparatus. Alternative embodiments include a stamped anti-flotation screen, a hollow central socket, and hollow, tapered bagel support rods. The hollow mouth of the handle allows a controlled tilting of the entire bagel cookware during the phases of cooking.
