Abstract: This cam has a cam lobe having opposite sinusoidal surfaces which have two rises and two reverse rises or two dips in 360.degree. of each sinusoidal surface with the rises in one such surface being opposite to the reverse rises in the other such surface, which sinusoidal surfaces will have full, centerline contact with a pair of bearings attached to the same connecting rod connected to a pair of pistons, these bearings being on opposite sides of the cam lobe and at one time being driven in one direction by one of the two pistons in each pair and then at another time in the opposite direction by the other piston in that pair. The surfaces of the cam lobe avoid friction or binding between the cam lobe surfaces and across the width of each bearing continuously through each revolution of the cam and of each bearing.

Abstract: The wash shield disclosed herein comprises a sheet material in substantially cylindrical shape having a slot running parallel to the axis of the cylinder, in which cylindrical shape a paint roller may be enclosed while a stream of wash water is directed to the surface of the roller for the purpose of removing paint therefrom. This improved wash shield has a support or centering means against which a corner of the handle of the paint roller may be pressed or abutted so as to position the axis of the roller in a desired location inside the wash shield. This centering means may be attached to and extended from the side wall of the shield or where the shield has a cover, this centering means may be situated on the inside surface of this cover. Such a cover may be at one end of the cylinder which is at the top when the cylinder is held in a vertical position, and the opposite end or bottom end is open and extends about 0.75 inch or more beyond the end of the roller contained therein.

Abstract: The process described herein produces a cam which has a cam lobe having opposite sinusoidal surfaces which have at least two rises and at least two dips in 360.degree. of each sinusoidal surface with the rises in one such surface being opposite to the dips in the other such surface. These sinusoidal surfaces are designed so that they may be in full, centerline contact with pairs of bearings attached to connecting rods, these bearings being on opposite sides of the cam lobe and at one time being driven in one direction by one of the two pistons in each pair and then at another time in the opposite direction by the other piston in that pair, the two pistons of that pair being connected to each other by the same connecting rod carrying the bearings which are adapted to press against the cam lobe. The surfaces of the cam lobe are designed to avoid friction or binding between the bearings and the cam lobe. An engine for which this cam is particularly useful is described in applicant's U.S. Pat.

Abstract: The treatment described herein comprises the process of reducing the soreness of irritated or excoriated areas surrounding the stoma of ostomy patients by the application of a sulfate or phosphate of barium, calcium, strontium or zinc, preferably barium sulfate. This finely divided powder may be in the form of a dry powder, an aqueous suspension or paste, or an ointment or cream. This treatment brings relief in a short time and curing of the irritation, generally within 24 hours or more.
