Inventor: GORBATY MARTIN L
IPC: C08L101/00
Filed: 1993-02-16
Abstract: Disclosed in this invention are novel asphaltic compositions and the method of making same. The compositions are made by combining an asphalt that contains sulfonate or sulfonic acid groups, a polymer preferably of butyl rubbers, styrene-butadiene linear diblock polymer, styrene-butadiene-styrene linear or radial triblock polymer and EPDM that has been sulfonated, and mixtures thereof, and a basic neutralizing agent that contains cations having a valence from +1 to +3. The amount of polymer is an amount less than 7 wt.% of total polymer-asphalt composition that is sufficient to produce an asphaltic composition having a viscosity at 135°C in the range of from about 150 cPs to about 2000 cPs or from about 3000 cPs to about 8000 cPs. The novel asphaltic compositions have improved viscoelasticity, softening point, and storage stability. The compositions can be used as binders in road paving applications.

Title: Voltage-controlled apparatus for battery-powered electronic devices
Inventor: MCNAIR BRUCE E
IPC: G06F1/28
Filed: 1993-03-31
Abstract: The frequency of a timing signal generated by a timing source apparatus for battery-operated, clock-driven electronic devices is reduced in a predetermined manner as the battery voltage decreases. The timing source is electrically connected to the internal clock of the device to dictate the speed of that clock. As the frequency of the timing source is decreased in response to lower battery voltage, the internal clock speed of the device is proportionately reduced, causing reduced power consumption and prolongation of the life or charge cycle of the battery.

Title: Light scattering light guide, manufacturing method thereof, and applied optical apparatuses
Inventor: KOIKE YASUHIRO
IPC: G02B6/04
Filed: 1992-09-25
Abstract: ABSTRACT A light scattering light guide, which is capable of converting a light flux of a relatively small cross-sectional area into a light flux of a relatively large area with high efficiency and uniformity, manufacturing method thereof, and applied optical apparatuses such as backlight light source apparatuses and light branching/mixing devices which make effective use of the characteristics of said light scattering light guide.

Title: Composition and method for temperature sensitive seed germination control
Inventor: STEWART RAY F
IPC: A01C1/06
Filed: 1991-12-03
Abstract: Coated organisms and particularly coated seeds are provided wherein the coating is comprised of one or more polymeric materials which form a coating having a temperature-dependent permeability with respect to a material such as water permeability. The polymeric materials used in making the coatings are relatively impermeable to the material such as water at cooler temperatures (less than optimum growth or germination temperatures) and relatively permeable at higher temperatures (at or greater than optimum growth or germination temperatures). The variable permeability of the coating prevents imbibition at lower temperatures and allows it at higher temperatures. Accordingly, coated seeds can be planted early in a planting season and undergo imbibition followed by germination under favorable moisture and temperature conditions.
