Abstract: A craft art form and system including patterns, paint, and applicators enables craft paint to form three-dimensional color dot matrix patterns having high degree of visual resolution and color saturation. Precisely located and closely spaced circles containing a standard set of color symbols are used to form designs in patterns. Each symbol in the standard set of symbols of the present invention represents an artistic expression which is permanently assigned to a particular color. Each color symbol has a darkness value which corresponds to the darkness value of the assigned color. The craft paint has the characteristics of forming a discrete uniform, homogeneous, three-dimensional bead to overlay the color symbol placed on each circle. This special beading paint can form beads placed very closely together (36 to 81 beads per square inch) without running together, yet retain sufficient fluidity to settle into smooth, substantially rounded, uniform beads.

Abstract: A gas analysis device for the remote detecting, measuring and recording of NO.sub.x, CO, CO.sub.2, HC and H.sub.2 O levels from the exhaust of moving motor vehicles. It utilizes a source of collimated infrared and ultraviolet radiation and includes a mechanism for receiving and measuring the infrared and ultraviolet radiation from its source, and another mechanism for measuring background infrared and ultraviolet radiation levels in the ambient atmosphere. The receiving mechanism splits the combined infrared and ultraviolet radiation into separate infrared and ultraviolet beams. A mechanism receives the separate ultraviolet beam and generates a signal indicative of NO.sub.x. Another mechanism splits the infrared beam into two to four components, and devices are positioned for receiving each of the infrared components and generating two to four signals indicative of, for example, CO, CO.sub.2, HC and H.sub.2 O. Another associated mechanism then computes and produces signals indicative of the amount of CO, CO.

Abstract: Soilborne rhizosphere-incompetent biocontrol agents can be converted into rhizosphere-competent agents by exposing them to a mutagenic agent and then screening the exposed rhizosphere-incompetent agent for a strain showing increased cellulase production. The increased cellulase production characteristic serves to convert the originally rhizosphere-incompetent agent into one which is rhizosphere-competent. Seeds of plants to be protected against various diseases can then be treated with the rhizosphere-competent strain. The roots of the plant, as well as its original seed, are protected by biocontrol agents produced by the disclosed process.

Abstract: An integrated semi-parabolic antenna/down converter MMDS receiving system wherein the support boom of a semi-parabolic antenna contains the down converter electronics. Located at the focal area of the semi-parabolic antenna are a pair of driven feed elements which are directly connected to the printed circuit board carrying the down converter electronics. The down converter is formed in an elongated shape to fit entirely within the formed hollow interior of the support boom. The down converter comprises a first printed circuit board which contains an RF filter located at the input end of the printed circuit board. The input of the RF filter circuit is directly connected to the pair of driven feed elements by soldering the legs of the driven feed elements directly to the input of the RF filter stage on the first printed circuit board. The RF filter is surrounded by an input ground shield which covers the RF filter circuit. The shield is soldered to the top and bottom ground planes of the printed circuit board.

Abstract: The self-contained sound effects system for a model radio controlled toy vehicle. The conventional internal control signals of the vehicle are detected by the present invention and are utilized to generate realistic sound effects on board the vehicle. The sound data and programming necessary to coordinate the realistic sound effects with the conventional on-board control signals are entirely contained on the vehicle. A microprocessor is used to provide the coordination of the sound data with the programming and the microprocessor modifies the sound effects with any changes in the on-board control signals by varying the pitch, timbre, amplitude, and the like of the sound effects. A communications port is also provided on the vehicle so that when connected with a remote computer, the sound data and programming can be selectively modified by the operator to add new sound effects or to change current sound effects and operating software.

Abstract: A method of providimg two-way communication between a plurality of channel units in a channel bank and a line interface circuit of a telephone system utilizing a receive direction protocol and a separate transmit direction protocol. The receive direction protocol identifies the channel unit to which provisioning data is to be delivered, increases the bandwidth of the voice data region in the time slot corresponding to the identified channel unit, superposes the provisioning data in the time slot with the voice data, and delivers the superposed data to the channel unit wherein the provisioning data is separated from the voice data. The transmit direction protocol utilizes the A and B signaling bits corresponding to the eighth bit of an identified time slot in the sixth and twelfth transmit frames wherein two bits of an eight bit status message is delivered on every other superframe. The two-way communication protocols occur without affecting or interfering with the PCM voice data.

Abstract: Apparatus for measuring an angular rate of turn employing vibrating elements which are so arranged that the reaction forces from both the driven deflection vibration mode as well as from the reaction deflections from the angular turn rate are contained within the assembly. The apparatus further employs means for selectively controlling the stiffness of the structure for undesirable modes of vibration while allowing maximum flexible coupling for the desirable modes of vibration thus minimizing the effects of outside vibrational influences and changing boundary conditions from causing errors in the turn rate signals. The assembly further employs unique non-contacting motion drivers and detectors for driving and sensing the movement of the elements without adversely affecting that motion. The apparatus further employs unique damping means which can dampen unwanted vibrational influence for selected modes and directions.

Abstract: A parabolic low wind load antenna for receiving incoming MMDS signals wherein the antenna is essentially constructed of two identically formed, one-piece reflective halves connected together to form a rectangular shaped parabolic antenna. Each of the reflector halves comprises a substantially U-shaped rigid frame being parabolically shaped in the length dimension and being parabolically shaped in the width dimension. A plurality of reflector elements of circular cross-section and of equal length are oriented in parallel relationship to each other and are spaced apart from each other at a predetermined spacing of about ten percent of the MMDS wavelength. The predetermined spacing is determined in a plane perpendicular to the path of the incoming signals and each of the reflected elements is connected at its terminal ends to the sides of the U-shaped frame. Each of the reflector elements is formed in a full parabolic shape in the width dimension.

Abstract: Attrition-resistant binders can be prepared by a process wherein a slurry of clay particles is brought to either a low pH level (e.g., 1.0 to 3.0) or to a high pH level (e.g., 14.0 to 10.0) and mixed with a phosphate-containing compound in a concentration of from about 2.0 to about 20.0 weight percent. Preferably, the resulting slurry is spray dried and the particulate products of the spray drying are then calcined to produce attrition-resistant binder particles.

Abstract: A firearms target is made of a target sheet bearing a predetermined target pattern backed with a layer of woven fabric of a contrasting color. The target sheet is a material, such as paper, which permits a projectile to pierce the target sheet leaving an opening of substantially the same size as the projectile. In contrast, the projectile pierces the fabric leaving a multitude of severed fabric strands which extend into the area of the fabric pierced by said projectile. When viewed from in front of the target, these severed strands are highly visible through the hole created by the projectile in the target sheet due to the contrasting colors.

Abstract: A system for deploying and retrieving a cover over a swimming pool. The cover is wound onto a motor driven reel. A guide spindle aligns the cover onto the reel during the winding process. A spool, also driven by the motor, has a tow rope wound on it. The tow rope is attached through a pulley system and secured to the cover to align the cover over the pool. Torque-limiting clutches on the reel and spool drive shafts compensate for changes in speed of the winding and unwinding of the tow rope and cover by allowing slippage of the drive shafts. An overriding clutch on the spool allows the spool to spin freely so the tow rope can be easily unwound from the spool by the movement of the cover. A friction brake band provides drag on the spool to prevent slack rope from accumulating. A photoelectric sensor detects full deployment and retrieval of the cover and stops the motor. A heating element is also provided to raise the temperature above the dew point to reduce condensation and corrosion in the system.

Abstract: Micron sized gas bubbles produced by electrolysis (e.g., oxygen and/or hydrogen gas bubbles by the electrolysis of water) are introduced into a flotation cell which is also provided with larger bubbles produced by sparging a gas such as air into the flotation cell. The mixed presence of both large bubbles and small bubbles serves to improve the recovery of various copper-containing ores. The small bubble producing electrodes can be retrofitted into an existing sparged gas driven flotation cell.

Abstract: A rubber stamp is disclosed which produces a special effect when the stamp is pressed against a medium to be imprinted therewith. The special effects generated by the stamp can include audible (sound and/or music), light (patterns and/or sequences), and/or aromas. A cavity in the wood block of the rubber stamp contains the electronic circuitry necessary to provide the special effects messages. A sensor is affixed within the wood block, such as a pressure sensitive switch between the block and the rubber stamp, so as to trigger the electronic cicuitry to issue the special effects message simultaneously with the imprinting of a visual image from the rubber stamp upon the desired medium.

Abstract: A unique method and system is disclosed for generating digital clock timing in a receiver for use in direct-sequence spread-spectrum digital communication systems wherein spread data is delivered from a transmitter to a receiver. The present invention provides at the transmitter frames of digital communication data with each frame having a plurality of time slots and with each time slot having a plurality of digital bits. The transmitter utilizes direct-sequence spreading codes for spreading the digital bits in the time frame. The direct sequence spreading codes each have the same fixed sequence length of M chips and, furthermore, the number of chips per bit CB to spread each digital bit is constant and fully aligned with each digital bit. The ration of M:CB is an integer and the ratio of time of each time slot to the time of the M chips also equals an integer. The spread frames of digital information are despread at the receiver with receiver provided identical direct-sequence codes.

Abstract: A system and method of driect-sequence spread-spectrum TDMA (or TDD) digital communication, wherein acquisition and tracking occurs for a plurality of frames having a predetermined number of time slots. One of the predetermined number of time slots in each frame is assigned for acquisition purposes and carries acquisition and sync digital information. The remaining time slots in each frame have assigned header bytes for tracking purposes. The assigned acquisition time slot is spread with an acquisition direct-sequence spreading code. The remaining time slots are spread with a communication direct-sequence spreading code. During acquisition, the signal strength in each successive time slot for each spread frame is measured for a given number of time frames. The peak is located within the given number of time frames through a major acquistion sweep and a refinement sweep. The major acquisition sweep and refinement acquisition sweep locate the frame and time slot boundaries of the transmitted signal.

Abstract: Lignin, or a lignin derived material, which has been significantly demethylated (e.g., the demethylated lignin found in the raffinate produced as a by-product of dimethyl sulfide production which can be carried out using the spent liquor from wood pulping operations) can be isolated by a process wherein an organic solvent is added to a lignin-containing aqueous solution. The organic solvent is typically a polar, and at least a partially water-immiscible substance such as, for example, ethyl acetate. The resulting lignin-containing aqueous solution/organic solvent mixture is acidified to produce a water layer which is discarded and an organic solvent layer which contains the demethylated lignin. Upon its recovery, the demethylated lignin is dissolved in an alkaline solution to which an aldehyde source is added to produce a resol-type resin. The aldehyde source may be formaldehyde in solution, paraformaldehyde, hexamethylenetetramine, or other aldehydes including acetaldehyde, furfural, and their derivatives.
