Abstract: A dumbbell system is provided including a body portion and a handle extending across an opening in the body portion. The dumbbell system is ideal for use in areas where space is limited.

Abstract: A dumbbell system is provided including a base weight member and a handle rotatably attached to the base weight member. A plurality of added weights are adapted to be removably mounted to the base weight member in order to provide a compact dumbbell system which has the capability of providing several weight increments in a compact assembly. The dumbbell system is ideal for use in areas where space is limited.

Abstract: This invention relates to a method for improving the efficiency with which fuel is burnt in a fuel burning apparatus, particularly an internal combustion engine, comprising dispersing an amount of at least one particulate lanthanide oxide, particularly cerium oxide, in the fuel. This invention further relates to tablets, capsules, compositions and liquid fuel additives suitable for dispersing a lanthanide oxide in fuel.

Abstract: A dumbbell system (10) is provided including a base weight member (12) having a ring-shaped body (14) and a handle (18) extending across an opening (16) in the ring-shaped body (14). A plurality of weight rings (20, 22, 24) are adapted to be removably mounted to the base weight member (12) in order to provide a compact dumbbell system which has the capability of providing several weight increments in a compact assembly. The dumbbell system (10) is ideal for use in areas where space is limited. The dumbbell (10) also provides for a unique balanced mass arrangement which alleviates undesired stresses on a user's wrist.

Abstract: A truck trailer or similar bulk storage area is heated by providing electrical resistance heaters in longitudinally-extending metal ducts extending from and to a short distance below the floor level. Electrical sheet resistance heaters are attached to the underside of the metal plate forming the duct top, each duct is placed between a longitudinally-extending pair of wooden floor boards, and a pair of ducts are placed side-by-side near each edge of the trailer bed or floor of the storage area.

Abstract: A process or acylating or sulfenylating 1-amino-2-phenyl-1-butene-3-ones to prepare the corresponding 4-acyl or 4-substituted-thio compounds provides intermediates useful for preparing herbicides.
