Abstract: A portable personal heating device including a heater and an optional heat suit is disclosed. The heater is adapted to be used with a removable heat source including a base to receive the heat source and a heat stack attached to the base. The heat suit is preferably a camouflaged poncho, which encompasses a user's body and the heater to keep warm and enhances the blending and camouflaging of the user relative to an environment. The personal heating device is simple, portable, lightweight and effective for outdoor recreations in winter.

Abstract: The present invention relates to N-propargylphentermine and its derivatives and the neuroprotective and anti-depressant activity of such compounds as well as therapeutic methods for such compounds.

Abstract: The present invention is directed to novel N.sup.1 -propargylhydrazines, N.sup.2 -propargylhydrazines and their salts in pharmaceutical compositions. The compounds according to the present invention have at least one of the following activities: monoamine oxidase-A inhibiting, monoamine oxidase-B inhibiting, anti-depressant, anti-anxiety and neuroprotectant activities. These compounds are useful as monoamine oxidase inhibitors and should be useful for the treatment of depression, anxiety and of neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease.

Abstract: A technique for providing a continuous underground tunnel between first and second spaced-apart points and for installing new cable, pipe or conduit is disclosed herein. This technique utilizes a boring device including means for boring through soil and a thrust conduit which pushes the boring device through the soil from a first starting point to a second end point as the device bores through the soil, whereby to form a tunnel between the two points. Thereafter, the cable to be installed within the tunnel is attached to the front end of the boring device and the latter is pulled back through the tunnel to its starting point by means of the thrust cable, thereby automatically pulling the new cable in place.

Abstract: A technique for providing a continuous underground tunnel is disclosed herein. This technique utilizes an elongated boring device including a forward facing, off-axis high pressure fluid jet which is rotated about the elongated axis of the device while the latter is urged forward through the soil, whereby to cause the device to bore a tunnel through the soil as it moves forward. In accordance with one feature of this technique, the boring device is steered by modulating the speed and/or the direction of rotation of its off-axis fluid jet in a way which depends upon the desired direction to be taken by the boring device within the soil. In accordance with another feature of the overall technique, the pitch angle of the boring device, as defined by its elongation axis, is monitored relative to a horizontal ground plane, independent of the roll position of the device.
