Abstract: A standup forward facing rowing watercraft is disclosed. The craft includes a hull having first and second opposed ends; a deck affixed to the hull, the deck including a surface for supporting a rider who may face in the direction of the movement of the watercraft; and an outrigger attached to the deck, the outrigger including a pivot point that extends outwardly from the deck, the pivot point being capable of accepting an oar. The oar is capable of rotating in the pivot point so as to allow a rider to employ a j-stroke to provide forward course correction when powering the watercraft with one oar. The outrigger can be adapted to include a second pivot point extending outwardly from the deck, the second pivot point being capable of accepting a second oar. The outrigger may preferably be adapted for longitudinal movement in relation to the deck of the watercraft.

Abstract: An adjunct actuator including an electric actuator motor and associated gear train providing motive power for remotely operating an output arm of the adjunct actuator. A lost motion clutch mechanism is provided between the gear train and the output arm. The lost motion clutch mechanism includes a floating sector gear driven by the gear train. The sector gear rides upon an arcuate rail formed on the actuator frame. The sector gear is driven to a neutral position by a spring when the electric motor is deenergized. The spring of the adjunct actuator is not preloaded during assembly of the adjunct actuator. The sector gear is disposed to drive an arcuate carriage which is pivotally mounted on the actuator frame to move about a common rotational axis with the sector gear. A pair of driving faces of the sector gear are interposed between a pair of driven faces on the carriage in a manner providing lost motion between the sector gear and the carriage.

Abstract: Calixarene derivatives, their synthesis and use as chloride channel blockers are described. Preferred calixarene derivatives are of the formula: ##STR1## wherein R is an acidic group or salt thereof, such as SO.sub.3 X or R.sup.1 SO.sub.3 X where X is H or Na, and R.sup.1 is ##STR2## where m=1-2, and R.sup.3 and R.sup.4 the same or different is each H or a C.sub.1-4 alkyl, or a nitrogen-containing group of the formula ##STR3## or A, wherein R.sup.5 is a C.sub.1-4 alkyl, R.sup.6 is a C.sub.1-4 alkyl and A is ##STR4## where R.sup.7 and R.sup.8, the same or different each is H or a C.sub.1-4 alkyl, and R.sup.9 and R.sup.10, the same or different, each is H or a C.sub.1-4 alkyl; R' is H or a C.sub.1-4 alkyl; and n is an integer of 4-8, preferably 4, 6 or 8.
