    摘要: Quadrol has been found to stimulate macrophage activity in warm blooded animals. As a consequence, Quadrol may be used to combat bacterial infection, remove degenerated tissue, and promote new tissue growth. Quadrol may be applied topically, e.g., as the active agent in a wound dressing.

    摘要: An improved surgical needle of the type having one or more cutting edges converging towards the needle tip and formed by the intersection of a plurality of planar surfaces, for use in cutting through hard body tissue material. The forward end of the needle has one or more smaller additional cutting edges located at the tip to aid initial insertion into the tissue. These additional cutting edges are formed by at least two additional intersecting planar surfaces at the tip portion. The needle is preferably curved in the reference plane defined by one of the cutting edges and the axis of the needle.

    摘要: A wrapping machine has film feed rolls driven through a one revolution clutch to advance a wrapper length of stock in each cycle, past a continuously driven cutter, to separately driven and intermittently operating sheet locating belts. First sensing means disengage the clutch when no articles are ready to be wrapped. Second sensing means stop the belts in correct wrapping position of the sheet. Movable pressure rollers hold sheets on the belts, to stop with belts. Electrically actuated lifting devices lift the rollers from the belts. Cyclically driven switch means and holding circuits are connected to successively engage an electric clutch to drive the belts while opening a circuit to a brake for stopping the belts and deenergizing the roller lifting devices, then deenergize and disengage the electric clutch while conditioning the circuit to the brake for completion by the second sensing device, then energize the lifting devices for lifting the rollers from the belts. Other cyclically actuated switches and holding circuits condition the first sensing means to disengage the one revolution clutch and retract a movable striker blade from coacting cutting relation with the cutter when the first sensing device is activated during a short interval near the end of the rotational cycle of the one revolution clutch.

    摘要: A novel group of amine formal polymers of the general formula: ##STR1## wherein R is hydrogen, --CH.sub.2 R" or ##STR2## R' is hydrogen or --CH.sub.2 R" and R" is hydrogen, alkyl or hydroxyalkyl, n is 1 to 8, m is 0 to 8 and R, R', and R" may be the same or different. The polymers may be prepared by reacting bis(haloethyl)formals with ammonia or primary amines and/or monoalkanolamines in the presence of aqueous alkali. The products may be used as, e.g., rust inhibitors, acid scavengers, antioxidants and epoxide and urethane curing catalysts. Certain of the polymers are especially useful as epoxide curing agents.
