Abstract: A desmodromic valve system which provides direct bidirectional displacement of a valve stem of an internal combustion engine without the aid of a rocker arm, utilizing a semirigid basket operating in conjunction with a plurality of cams for each valve. The basket is disposed about the camshaft of the engine and secured to the valve stem by an integral retainer on a bottom portion of the basket, and is constrained to motion along the valve stem axis. The basket has a pair of downwardly oriented cam followers in the upper portion thereof, spaced apart from the valve stem axis. A central cam and a parallel pair of side cams are fixedly mounted on the camshaft so as to rotate therewith, the cams substantially surrounded by the basket and cooperating therewith to provide reciprocating valve action with positive bidirectional drive.

Abstract: A unitary cam follower and valve preload spring for a desmodromic valve mechanism having opening and closing cams mounted in parallel on an overhead camshaft so as to facilitate positive bidirectional drive of a valve. The device comprises a generally tubular spring member of oblong transverse cross-section, a shaped extension spring, preferably a band or basket. The spring member is configured to be nonrotatably mounted on the camshaft with its longitudinal axis parallel to the camshaft axis and its major axis aligned with the valve stem axis, substantially surrounding the opening and closing cams circumferentially and engaging the valve stem and closing cam so as to pull the valve stem in response to an upward force applied to the upper portion of the spring member by the closing cam.

Abstract: A water-stable and water-soluble ceramic precursor is provided, containing at least one Group III element. Also, a metal acid salt complex is provided comprising (1) bismuth, lanthanum, and titanium, and (2) a polyether acid. In addition, methods are provided for preparing the Group III metal acid salt complex and the Bi, La, Ti acid salt complex comprising a bismuth polyether acid salt complex, a lanthanum polyether acid salt complex, and a titanium polyether acid salt complex. Finally, devices that include lanthanum-doped bismuth titanate as the active component are provided, as well as a water-stable and water-soluble gallium polyether acid complex.

Abstract: A temperature-compensated capacitor device has ferroelectric properties and includes a ferroelectric capacitor using a ferroelectric material such as a metal oxide ferroelectric material, a negative-temperature-variable capacitor using a negative-temperature-coefficient-of-capacitance material such as a metal oxide paraelectric material, and an electrical series connection between the negative-temperature-variable capacitor and the ferroelectric capacitor. The temperature-compensated capacitor device may be formed as an integrated layered structure, or as separate capacitors with a discrete electrical connection therebetween.

Abstract: A self-supporting panel for a fence has a skewed anchor sleeve welded to each lower corner of the panel for receiving a stake to fasten the anchor sleeve to the ground or other support. Two panels are joined by a pin in the open ends of abutting lower rails from each panel and by a cap joining the upper ends of adjacent stiles from each panel.

Abstract: A method of treating and effectively alleviating the symptoms of tall fescue toxicosis in domestic farm animals includes the administering of thiamin at therapeutic levels into the feed for the animals. A method of preventing tall fescue toxicosis in animals grazing or feeding on endophyte infected tall fescue is also provided.

Abstract: A plurality of elongated tanks positioned in parallel relationship with respect to each other are swingably interconnected at their aligned ends to provide a yieldingly undulating breakwater apparatus. The buoyancy of each of the tanks is individually adjustable so that the ratio of floating tanks to submerged tanks, and the various depths thereof, can be altered to suit the prevailing wave and current characteristics of a particular installation site.
