Abstract: The present invention is directed to cinnolinyl and quinolinyl pyrazol-4-yl-pyridine compounds which are allosteric modulators of the M4 muscarinic acetylcholine receptor. The present invention is also directed to uses of the compounds described herein in the potential treatment or prevention of neurological and psychiatric disorders and diseases in which M4 muscarinic acetylcholine receptors are involved. The present invention is also directed to compositions comprising these compounds. The present invention is also directed to uses of these compositions in the potential prevention or treatment of such diseases in which M4 muscarinic acetylcholine receptors are involved.

Abstract: Apparatus is provided for improving the coupling between an external inductive transmitting coil and an internal inductive receiving coil to transmit power and/or data to the receiving coil from the transmitting coil. The structure includes a coupling coil inductively coupled to the transmitting coil to increase the Q factor and hence the energy transfer between the transmitting coil and the receiving coil.

Abstract: A method of impregnating polystyrene beads with an aliphatic hydrocarbon, rendering it into expandable polystyrene. The method involves the use of an improved impregnating solution or bath. The solution includes water, an expanding agent, the polystyrene beads and soaps which act as anti-agglomeration agents. The beads are maintained in the solution for a selected time period and at a temperature and pressure suitable to permit the expanding agent to impregnate the beads. The beads are then separated from the solution and, after drying, they are ready for use, no further processing being required.

Abstract: A protective vest for use by motorcycle riders, snow mobile riders, rodeo riders and the like provides an integral inner vest of cushioned material such as foam having a vertical opening at the front portion thereof and a pair of arm openings allowing it to be dorned by a wearer. A lowermost circumferential armor plate of hardened plastic, for example, extends from the vertical opening 360.degree. degrees around the wearer and vertically from the lowermost portion of the vest upwardly a distance terminating at the middle portion of the vest. The hardened armor plate is bonded, for example, directly to the innermost foam vest. A pair of bilaterally symmetrical hardened plates extend from the mid portion of the vest upwardly over the shoulder of the vest and downwardly onto the back portion thereof forming a pair of bilaterally symmetric continuous armor plated panels separate from the lowermost panel and from each other.
