The control system maintains the tank heating unit effectively turned off and turns the external heat source on in response to an indication from the tank heating unit that there is a demand for hot water.  The control system (32) also turns the external heat source (14) off in response to an indication from the tank heating unit that the demand for hot water has been satisfied.  Further, the control system is responsive to an external condition for turning the external heat source off,  turning  the tank heating unit on,  and maintaining the external heat source off and the tank heating unit on until the tank heating unit indicates that the demand for hot water has been  satisfied.  The tank heating unit need not be modified for use with the control system.

Abstract: La présente invention concerne un dispositif de réalisation d'un découpage de peinture dans un coin formé par l'intersection de deux surfaces planes et disposées à angle droit l'une par rapport à l'autre. Un tel dispositif comporte une première partie munie d'une plaque rectangulaire destinée à masquer à partir du coin une portion d'une première des deux surfaces située le long de ce coin, ainsi qu'un rouleau à peindre. Ce rouleau à peindre est muni d'un manche formé par une tige et portant à une extrémité le rouleau. Cette tige est pliée de telle sorte qu'elle coopère avec un système de guidage de la première partie pour, lorsque cette première partie masque à partir du coin la portion de la première surface, positionner le rouleau à peindre et guider tout mouvement le long du coin transmis à celui-ci par l'intermédiaire de son manche de manière à permettre de peindre à partir du coin une portion de la seconde des deux surfaces correspondant à la portion de la première surface masquée par la première partie. Donc, en manoeuvrant de façon appropriée la première partie pour masquer une portion de la première surface à partir du coin et le rouleau à peindre par l'intermédiaire de son manche coopérant avec le système de guidage, il est possible de peindre à partir du coin une portion de la seconde surface sans enduire de peinture la première surface masquée par la première partie, pour ainsi réaliser le découpage de peinture. L'utilisation du dispositif selon l'invention n'est cependant pas limitée à la peinture, mais s'applique également à tout enduit ou revêtement sous forme liquide.

Abstract: SAO-1-36904C/YT/84.     ABSTRACT OF THE DISCLOSURE         A novel star block copolymer represented by the general formula as shown below and a process for the produc-tion thereof are described.  The copolymer has superior physical properties, particularly impact strength and, further-more, is reduced in coloration.  Thus the copolymer can find numerous uses;  for example, it can be used in preparation of fibers, foams, automotive parts, and electrical components.          The copolymer is produced by copolymerizing a star-shaped polyether prepolymer and a lactam, said prepolymer being prepared by reacting a star-shaped polyoxyalkylene having at least 3 terminal hydroxy groups and an N-chlorocarbonyl lactam in the presence of an anionic polymerization catalyst.             In this formula, all the symbols are as defined hereinbefore.

Abstract: ABSTRACT OF THE DISCLOSURE           A tape cassette comprises a cassette housing including an upper section and a lower section.  The upper section has a top wall including an opaque portion and a transparent window plate, and the lower section has a bottom wall formed with a pair of hub-receiving apertures therein.          The top and bottom walls lie substantially in parallel spaced-apart planes.  A pair of tape reels are mounted within the housing, each of the tape reels being formed with a hub and having an axis extending in a direction substantially normal to the planes of the top and bottom walls. The hubs are respectively rotatably received within the hub-receiving apertures.  A rib is formed on the top wall and projects therefrom towards the tape reels.  Each of the tape reels is movable axially between a lower position limited by engagement with the bottom wall and an upper position limited by engagement with the rib.  The rib is spaced apart from the bottom wall a distance sufficient to enable axial movement of each of the tape reels away from the bottom wall in order to facilitate rotation of the tape reels but insufficient to enable withdrawal of the hubs from the respective hub-receiving apertures.  The upper section of the cassette is formed by a method employing a mold having stationary and movable cores.

Abstract: "ABSTRACT OF THE DISCLOSURE"           A catalyst composition composed of a crystalline aluminosilicate Y zeolite, normally having a silica-to-alumina mole ratio of about 6.2 or above, in combination with a porous, inorganic refractory oxide.  The Y zeolite contains ion-exchanged rare earth cations and ion-exchanged Group VIII noble metal cations.  The combination of the zeolite and the refractory oxide contains between about 4.5 weight percent and about 6.5 weight percent water, preferably between about 4.5 and 6.0 weight percent.  Such a catalyst containing the recited amount of water has been found to have consistently high activities when used as a catalyst in a hydrocracking process.  The Y zeolites used as part of the catalyst are typically prepared by contacting an ammonium-exchanged Y zeolite with an aqueous solution of ammonium fluorosilicate.
