Methods of temporarily alleviating symptoms of hypersomnia or mental fatigue or drowsiness or temporarily suppressing appetite by administering to a human or animal having one or more of the aforementioned symptoms an effective amount of piperoxan together with a suitable pharmaceutical carrier. Piperoxan is also useful for potentiating the effects of anti-depressant drugs.

A method of selectively alternating the oxidation, acid wetting, and leach cycles used on a low grade copper bearing ore or overburden body to thereby enhance the rate of copper recovery therefrom. Control of the pH of the aqueous solution used during the acid wetting phase to a pH value within the range of 1.0 to 2.0 has been found to be unusually significant.

A method for increasing the yield of crops involving application of an s-triazinedione such as 3-(4-chlorophenyl)-6-methoxy-s-triazine-2,4(1H,3H)-dione. A preferred use of the invention is to increase the number of inflorescences or the number of grains per inflorescence on corn, wheat, and rye by applying the s-triazinedione to the plant at a time that will affect floral differentiation or development.

Apparatus for increasing the density of data tracks on the recording surfaces of a disc memory of the type having at least one pre-recorded servo track which is continuously read by a servo head whose output signal changes with its position relative the track and is constantly adjusted to maintain a predetermined servo head output signal condition, without increasing the number of servo tracks in the memory. The improvement comprises a servo head having a plurality of flux paths, each passing th...

A device for inserting or moulding into a tire tread to increase traction and stabilize the tread comprising an elongated body having an end surface and installed in the tire so that the end surface is spaced inwardly of the tread surface in a manner defining a recess. As the tire moves along a supporting surface such as a road, the portion containing the device is brought into and out of maximum stress thereby varying the volume of the recess in a manner creating suction therein which increases...

A weight increasing device adapted to be mounted on an ice skate between the two posts supporting the boot of the ice skate. The device fits tightly between the two posts and abuts against each other. The device comprises a block which constitutes the mass of the device and a leg which projects outside said mass and is spring mounted so as to exert a longitudinal tension between the two posts.

The inherent viscosity of halooxirane-methacrylate copolymers is increased to produce semi-solid rubbery copolymers by treating said copolymers with an organolithium treating agent.

Methods for increasing the yield of crops comprising applying thereto an allophanimidate such as methyl 4-(p-chlorophenyl)-N-methoxycarbonylallo-phanimidate or methyl 4-(p-chlorophenyl)-N-methylthio-carbonylallophanimidate. A preferred use of this invention is to increase the number of inflorescences or the number of grains per inflorescence on corn, wheat, and rye by applying the allophanimidate to the plant at a time that will affect floral differentiation or development.

A method of increasing the thermostability of organopolysiloxanes and compositions containing the same comprising introducing into organopolysiloxanes and compositions based on them 0.01 to 10 weight parts of a polyethynylpyridine or synergistic mixtures of 0.01 to 10 weight parts of a polyethynylpyridine with 1 to 10 weight parts of metal salts or an oxide of a metal per 100 weight parts of organopolysiloxane. The resulting thermostable organopolysiloxanes and compositions based on them find ap...

A method for increasing the choroidal blood flow which comprises administering to a subject in need of such increasing a 13,14-dihydro-15-keto-20-ethyl-prostaglandin F, a pharmaceutically acceptable salt thereof or a lower alkyl ester thereof.
