    Abstract: One embodiment provides an asymmetrical nozzle housing within a nozzle base of a sprinkler which, when rotated, changes its angular orientation relative to the nozzle base. Since the nozzle is disposed within the nozzle housing, it similarly changes angular orientation relative to the nozzle base, thereby modifying the trajectory of ejected water during irrigation. In this respect, a user can change the trajectory of a watering stream by simply rotating the nozzle housing.

    Abstract: A rotary sprinkler having a rotatable nozzle assembly for watering an arc of ground traversed or swept by the nozzle assembly as the nozzle assembly rotates is disclosed. Oscillating rotation is achieved via a drive train that includes a trip spring that is drivable between first and second positions for reversing the direction of nozzle rotation. The sprinkler also includes: a variable trajectory nozzle; secondary opening adjacent the variable trajectory nozzle; an automatic break up screw configuration; a substantially constant speed turbine assembly; a bypass stator; a reversing cluster gear planetary drive with a uni-directional turbine; an overcenter reversing mechanism; a nozzle base clutch; an adjustable arc mechanism, solid arc limit stops, a snap ring installation method and an adjustable pilot valve which uses visual indicia.

    Abstract: Infinitely water soluble, storage stable, low molecular weight, amine-modified resins/binders (e.g., phenol-formaldehyde resole resins and binders made therefrom) are used to produce low odor fiberglass products, such as fiberglass insulation for automobile headliners and room dividers. The cured, bonded fiberglass products have low TMA (trimethylamine) emission because the free formaldehyde in the resin has been scavenged with melamine, which resists thermal decomposition, and because the binder contains a relatively low urea content, which is a TMA contributor. The resole resin production process includes adding two different formaldehyde scavengers (e.g., melamine and urea) to produce a modified phenol-formaldehyde resole resin. This resole resin is produced into a binder by mixing with water, optionally in the presence of a latent acid catalyst (e.g., an ammonium salt of a strong acid). The binder can be applied to a fiberglass base material, dried, stored for an extended time period, and then cured and shaped into a final desired shape.

    Abstract: A bilateral circuit is operable for transmitting signals in two directions without generation of ringing due to feedback caused by the insertion of the circuit. The circuit may include gain for each of the signals to provide a bidirectional amplifier. The signals are passed through two separate paths, with a unidirectional amplifier in each path. A controlled sampling device is provided in each path for sampling the two signals. Any feedback loop between the two signals is disrupted by providing a phase displacement between the control signals for the two sampling devices.
