Abstract: An agent for improving the flow properties of middle distillates, said agent being a solution consisting essentially of a solvent having a boiling point of at least 50.degree. C. at 760 mm Hg and a graft copolymer formed from(a) as the grafting monomer, 20 to 80 percent by weight of an ester of methacrylic acid and a C.sub.8 to C.sub.15 alkanol, and(b) as the backbone polymer, from 80 to 20 percent by weight of an ethylene/vinyl acetate copolymer or of a terpolymer formed from ethylene, vinyl acetate, and a substituted olefin having form 3 to 50 carbon atoms, said backbone polymer having a reduced viscosity of 6 to 50 ml/g and degree of branching between 3 and 15 CH.sub.3 groups per 100 CH.sub.2 groups.

Abstract: A swivel joint includes a central member having a joint barrel having a first insertion hole and a second insertion hole parallel thereto, a slot communicating with the first insertion hole, a pair of first confronting inner surfaces defining the first insertion hole and having a pair of first locking ledges respectively, and a pair of second confronting inner surfaces defining the second insertion hole and having a pair of second locking ledges, the first inner surfaces including respective slanted surfaces slanted progressively inwardly toward each other. A retainer member includes a retainer fitted in the slot and a pair of first resilient legs projecting from the retainer and inserted in the first insertion hole. The first resilient legs having respective first locking fingers engaging the first locking ledges, respectively, and slidable respectively on the slanted surfaces under resiliency of the first resilient legs.

Abstract: A bathtub wall surround kit is disclosed. The kit includes a plurality of panels adapted to be secured to the walls of a bathtub opening with each of the panels having a vertical edge adapted to be disposed in overlapping relation to a corresponding vertical edge of the next adjacent of the panels. It also includes a plurality of vertical seals for joining the corresponding vertical edges of the overlapping panels in substantially watertight fashion where each of the vertical seals includes a panel-receiving channel formed by a pair of spaced apart walls joined by a channel-defining bottom wall along with a seal adapted to cooperate with the overlapping panels.

Abstract: A glazing unit is sealed into an extruded frame member by utilizing a piece of sealing tape which is impervious to air and water and which is disposed in sealing relation to the glazing unit. The tape is divided intermediately into a first portion adjacent one edge and a second portion adjacent the other edge, the first tape portion having adhesive on one surface, and the second tape portion having adhesive on the other surface. The first tape portion is adhered to a flat part of the extruded frame member adjacent the glazing unit with the adhesive surface away from the glazing unit. The second tape portion extends substantially at right angles with respect to the first, and is adhered to the inner pane of the glazing unit.

Abstract: A pole assembly includes an elongate tubular pole releasably locked or held to a base plate. Spaced apart bores are formed in the tubular pole by forming elongate partial bores and closing same with elongate clamp members. The bores so formed are aligned with bores in the base plate to form aligned bore passages each of which houses a spindle. Each spindle is mounted in the tubular pole and a locking device engages each spindle and the base plate to releasably lock the pole to the base plate via the spindles. The assembly has particular utility in the case of an extruded metal pole wherein bores are not readily formed, and additionally overcomes disadvantages associated with the welding of a pole to a base plate.

Abstract: The invention herein is directed to an improved apparatus used for facilitating the process of affixing rectangularly shaped sheets of rubber roofing material to the upper surface of a roof, in which process a plurality of bonding plates are used to bond the rubber roof sheets to the upper roof surface. The invention relates to an improved integrated bonding plate apparatus used as stated, wherein an adhesive material is deployed on both the upper and lower surfaces respectively of such bonding plate apparatus; and wherein such plate has integrally emeshed between the upper and lower surface both a rubber binder plate and a concentrically disposed metallic plate.
