Title: Amplifier with reduced input capacitance
Inventor: MADAFFARI PETER L
IPC: H03F1/14
Filed: 1998-04-27
Granted: 2002-07-16
Abstract: A JFET preamplifier for use with a high impedance transducer, having an inherently capacitive input bias impedance. The capacitance of the input bias impedance is effectively neutralized by capacitively coupling the JFET gate bias circuit to the source electrode of the JFET. The JFET preamplifier is configured as a source follower which reduces any capacitance between the JFET gate and source electrode by the open loop gain of the amplifier. By capacitively coupling the JFET gate bias circuit capacitance to the JFET source electrode, the overall input capacitance of the preamplifier stage is reduced.

Title: Chemically induced permeability enhancement of subterranean coal formation
Inventor: BROSS STEPHEN V
IPC: E21B43/26
Filed: 1998-04-29
Granted: 2003-01-07
Abstract: A method for increasing the permeability to methane of a subterranean coal formation by chemically stimulating the formation of cleats in the coal formation in order to increase the rate of methane production from the coal formation. The method comprises injecting a gaseous oxidant into the coal formation to stimulate the formation of cleats in the coal formation; and thereafter producing methane from the coal formations at an increased rate. The gaseous solution comprises ozone, oxygen and combinations thereof. The completion of wells penetrating a coal formation is facilitated by injecting a gaseous oxidant into the coal formation surrounding the well prior to forming a cavity in the coal formation around the well.

Title: Seed coating composition of gypsum with molybdenum
Inventor: NI BING-RUI
IPC: C05D3/00
Filed: 1998-05-01
Granted: 2006-02-14
Abstract: Embodiments of a coating composition and coating method for seeds are described, the coating including molybdenum and a sulfur-containing component and being for improving seed and seedling performance. The preferred molybdenum source is molybdenum trioxide, and the preferred sulfur source is gypsum. After planting, the seed coating provides protection for the seed during dry spells until moisture is received and seed growth is established. During the establishment period for legumes, the invented seed coating serves as a protective coat for the seed under adverse growing conditions, such as temperature and moisture extremes. Within a few days of emergence of legume seedlings, the invented coating stimulates and/or feeds the Rhizobium bacteria that is in place on the seed and speeds up formation of the Rhizobium, which fixes/feeds nitrogen to the plant. The coating and method may also include inoculation with Rhizobium, and, optionally, other nutrients, pesticides, or herbicides and a binder.
