Abstract: A crosslinker composition is prepared from a reaction mixture including: (a) a prepolymer including a reaction product of a prepolymer mixture including: (i) a polyfunctional isocyanate; and (ii) a first compound comprising two or more active hydrogen groups, where the polyfunctional isocyanate and/or the first compound comprising two or more active hydrogen groups includes a greater than two functional isocyanate and/or active hydrogen groups, respectively; and (b) a polyfunctional hydrazide. The crosslinker composition is not self-crosslinkable. The crosslinker composition has an acid value of at least 15 based on total resin solids of the crosslinker composition.

Abstract: A retractable cocking assembly with hooks slidingly secured to a crossbow track. In a default or non-actuated position, the hooks are positioned forward of the uncocked bowstring. The hooks are drawn in a rearward direction to engage the bowstring and to pull the bowstring to its cocked position. When the bowstring is secured in a trigger catch in the cocked position, a user engages a release member that causes the hooks to return to the default position at the forward end of the crossbow track. A continuous force springs pull the hooks forward into the default position when the release member is engaged.

Abstract: A worm gear crank cocking device (“CCD”) for a crossbow to draw a bowstring from a released position to a cocked position. A user rotates a receptacle of the worm gear CCD to draw hooks rearward along the crossbow track to engage the bowstring and to draw the hooks with the bow string to a catch to place the crossbow in the cocked position. The worm gear CCD provides an automatic stop. If a user stops rotating the receptacle of the worm gear CCD, the hooks remain stationary on the track. A release mechanism is provided that disengages spools winding the cords attached to the hooks so that the hooks may return to their starting position forward of the released bowstring.

Abstract: A crossbow trigger assembly with a nock sensor enabling the catch to release the crossbow string only when a nock of an arrow is properly engaging the crossbow string. The trigger assembly also contains a bypass feature for deactivating the nock sensor to cause release of the crossbow string from the catch when a user activates a release switch. The bypass feature can only be activated when retractable hooks are positioned to receive the crossbow string near the catch, thereby preventing a dry fire of the crossbow string.

Abstract: A modular AFM/SPM which provides faster measurements, in part through the use of smaller probes, of smaller forces and movements, free of noise artifacts, that the old generations of these devices have increasingly been unable to provide. The modular AFM/SPM includes a chassis, the foundation on which the modules of the instrument are supported; a view module providing the optics for viewing the sample and the probe; a head module providing the components for the optical lever arrangement and for steering and focusing those components; a scanner module providing the XYZ translation stage that actuates the sample in those dimensions and the engage mechanism; a isolation module that encloses the chassis and provides acoustic and/or thermal isolation for the instrument and an electronics module which, together with the separate controller, provide the electronics for acquiring and processing images and controlling the other functions of the instrument.
