    Abstract: A skylight shutter is driven by a battery-powered d.c. motor through transistor switches operated by Schmitt triggers. A voltage dividing network derives the trigger signals by comparing the resistance of a photoresistor and a variable resistance, whose value determines the direction and degree the shutters are moved. A night sensor operates the Schmitt triggers independently of the remaining circuit for placing the shutters in a closed position to minimize radiation losses during evening hours.

    Abstract: A method for bonding two objects by means of the following two adhesives:(A) a moisture-inducible room temperature anion polymerization curing adhesive composed essentially of at least one anion polymerizable compound selected from the group consisting of an .alpha.-cyanoacrylate compound of the formula: ##STR1## wherein R is an alkyl group having from 1 to 16 carbon atoms, an alkoxyalkyl group having 2 to 16 carbon atoms, a haloalkyl group having from 1 to 16 carbon atoms, a cyanoalkyl group having from 2 to 16 carbon atoms, an aralkyl group having from 6 to 12 atoms, an acyloxyalkyl group having from 2 to 16 carbon atoms, a cycloalkyl group having from 3 to 16 carbon atoms, an alkenyl group having from 2 to 16 carbon atoms or an aryl group having from 6 to 12 carbon atoms, and a 1,1-disubstituted diene compound of the formula: ##STR2## wherein each of R.sup.1 and R.sup.2 which may be the same or different, is a hydrogen atom, an alkyl group having from 1 to 5 carbon atoms, an aryl group, an aralkyl group having from 6 to 12 carbon atoms or a halogen atom, R.sup.3 is a hydrogen atom or a methyl group, each of X and Y which may be the same or different, is a cyano group, a carboxylic acid ester group having from 2 to 12 carbon atoms, an ethylsulfone group, a phenylsulfone group, a formyl group, an acetyl group, a benzoyl group, an amide group, a diethyl sulfonyl group, or a phenyl group; and(B) a room temperature self-curing adhesive containing from 0.05 to 50% by weight of an anion polymerization accelerator, said self-curing adhesive being selected from the group consisting of (1) a room temperature moisture-curing adhesive, (2) a room temperature curing two-part type epoxy resin adhesive, and (3) a room temperature curing synthetic resin aqueous emulsion adhesive, which comprises applying said two adhesives (A) and (B) at the bonding interface of the objects so that they do not contact each other and pressing the objects to each other to bring the two adhesives in contact with each other.

    Abstract: A skylight shutter is driven by a battery-powered d.c. motor through transistor switches operated by Schmitt triggers. A sun sensor circuit generates a first shutter control signal so the shutter tracks the sun and passes maximum light. A room sensor circuit generates a second control signal which overrides the first control signal to reduce the room light to a desired selected level. A night sensor circuit overrides the first and second control signals for closing the shutters to minimize radiation losses during the night.
