Disclosed is a pointing compound for use in making repairs particularly to road surfaces. In accordance with the invention, the pointing compound comprises a mixture of mildly air blown bitumen, at least 25% by weight of polyolefin material selected from polyethylene, polypropylene and copolymers thereof and 10 to 40% by weight of a high boiling aromatic mineral oil. The amorphous polyolefin material preferably has a molecular weight ranging from 25,000 to 30,000 and a viscosity at 170.degree. C...

A musical instrument being, preferably, a compound drum, is provided having a plurality of distinct percussion chambers which may be contiguously incorporated into a single drum shell under a single continuous drum head, wherein this head may include a plurality of distinct surfaces.

A novel anthracycline antibiotic designated rudolphomycin is produced by fermentaion of Actinosporangium sp. ATCC 31127 and isolation of the new antibiotic free of substances co-produced therewith. Rudolphomycin and its pharmaceutically acceptable salts exhibit antimicrobial activity and inhibit the growth of mammalian tumors.

A compound slingshot comprises a longitudinally extending support shaped for holding by a user, an elongate resilient member having one end attached to the support, and a cam rotatably mounted on the support and having an eccentric marginal surface. A flexible line has one end connected with the free end of the resilient member, and the other end attached to and wound about the marginal surface of the cam. A projectile receiver is operably connected with the cam by a second flexible line, whereb...

A bow of the compound type for use in archery, having an upper and lower limb pivotally mounted at opposite ends of an elongated central frame member having a hand grasp portion formed thereon. First and second pivot members having continuously variable leverage characteristics are each connected to both the upper and lower limbs. When the drawstring is pulled back toward the cocked position, the limbs pivot and the variable leverage pivot members rotate from the position of least leverage to po...

Herbicidal compounds are the compounds having the formula ##STR1## wherein R represents H or CH.sub.3 and X represents H or Cl.

This invention relates to improving the internal combustion and internal use of fuel in reciprocating engines, and more particularly to reciprocating engines which are compounded in order to effect extension of the expansion event of the four-event work cycle of such engines and which are enabled especially thereby to receive and use, for the furtherance and prolongation of the combustion process, secondary air inducted by such engines or made available by external means, said air being directly...

Compound bow having two eccentric wheels or cams at each end. One of the wheels may be quickly manually adjusted with respect to the other without disassembling the strung bow to adjust the magnitude of drop off at full draw without significantly changing the draw length or peak weight. Also, a ball and socket type quick connect and disconnect device is provided for dead ending the bow cables or strings to the eccentric wheels or cams.
