Abstract: A hammer has a nail-removing claw located at a top portion of the hammer head between the poll and the handle. The novel claw is a pair of opposing jaws defined by a rearwardly opening V-shaped slot which is accessible from the side and rear of the hammer head. A second novel nail-removing claw is located in the throat of the hammer head between the poll and the handle. This claw consists of a pair of opposing jaws defined by a downwardly opening V-shaped slot.

Abstract: A liquid distribution device having preferred utility as a lawn sprinkler head consists of a hollow chamber having continuously curved interior walls and having a series of exit ports disposed therein. The interior chamber walls are structured to create a rapidly rotating turbulent mass of fluid in the chamber, producing a rapidly directionally unstable flow of discrete drops from each exit port. The chamber is preferably ellipsoidal in shape, and has a total exit-port cross-sectional area greater than that of the fluid inlet to the chamber.

Abstract: An improved recycling apparatus for particulate asphaltic concrete comprises a rotatable drum in which the particulate composition is gradually heated between an input end and an output end having a retractable chute extending into a port at the output end for recovering composition of a selected temperature. The chute contains a temperature sensing device, and the apparatus preferably includes a drive means for inserting or retracting the chute, and thermostat means for selecting a product temperature whereby the drive means causes the chute to be extended into the drum to recover the composition of a selected temperature. In another embodiment, the drum includes first, second, and third lifters each extending along different respective lengths of the drum interior to achieve different exposure of the particulate composition to the heating gases in the drum in the respective different drum sections to achieve improved heating and mixing efficiency.

Abstract: An improved process for recycling asphaltic concrete comprises introducing asphaltic concrete particles at one end of an elongated rotating drum while supplying flame and hot gases of combustion to the drum at the opposite end, and introducing virgin aggregate into the drum intermediate the two ends. The asphaltic concrete is heated as it travels along a portion of the length of the drum and is recovered just prior to reaching the position along the drum length at which the aggregate is introduced. The aggregate is heated as it travels toward the end of the drum at which the flame and hot gases are introduced. Heated aggregate may be returned to the drum for further heating, and may be directed to the opposite drum end and mixed with the asphaltic concrete in a section of the drum.

Abstract: A casing incorporates a spool having a cable wound thereon. One end of the cable is fixed to the spool and the other end passes from the casing.
