Abstract: A mechanical delay timer for operating either a toggle or a rocker-type wall switch to change the position of the switch after a preset interval includes a spring powered timer that drives a cam which, in turn, causes movement of an actuator that is arranged to engage either the toggle lever of a toggle wall switch or the rocker member of a rocker-type wall switch to move the switch from one position to another. The timer mechanism is contained within a housing that attaches to a timer base which, in turn, mounts over the existing cover plate of a conventional wall switch.

Abstract: A casket and burial system for human remains includes a casket fabricated from plastics and polymer composites, such as glass-fiber reinforced plastic. The casket includes a base member, a cover member fitting atop the base, and top and bottom closure panels having one or more ports for use in replacing the ambient atmosphere within the sealed casket with a selected gas or fluid such as nitrogen, or to inject a plastic foam into the free space remaining in the casket. The casket is preferably interred in a vertical attitude as that arrangement allows up to four caskets to fit within a standard grave plot.

Abstract: A multi-compartment liner bag is disposed within a receptacle and includes a first compartment having a height that is greater than that of the receptacle and a volume that is at least about equal to that of the receptacle. A second bag compartment is attached to and folds to the side of the first compartment when placed in the receptacle and has an entry folded over the receptacle top to form at least a visual seal to the compartment contents. Indicia means, which may be either visual or tactile, are provided along the second compartment entry to allow easy location of the compartment entry.

Abstract: A char containing less than 5% volatile matter is produced by pryolyzing shredded scrap vehicle tires and other rubber scrap material in an externally heated retort until the rubber is completely decomposed and until the temperature of the gases produced by the pyrolysis process reaches at least 500° C. The char is then subjected to resonance disintegration of an intensity sufficient to produce an unltrafine, particulate carbon product. In a preferred embodiment, essentially 100% of the individual carbon product particles are smaller than about 8 microns, and that product displays a dispersion coefficient in rubber of greater than 87%. The surface properties of the carbon product particles may be further modified by reacting or coating the carbon with chemical compounds or coating agents during or immediately after the resonance disintegration to tailor the properties of the carbon product to its use.

Abstract: The flow rate of water passing into a weir box and over a weir that is mounted on the weir box is determined using a sensor to continuously or intermittently obtain a measure of the water level within the weir box relative to the bottom of the weir notch to thereby determine the head of the water flowing over the weir which, in turn, translates into flow rate. The sensor is located in the interior of the sump which is in fluid communication with water within the weir box. The sump is positioned deeply enough within the ground so that the sensor is below the frost line and is not damaged upon freezing of the water within the weir box.

Abstract: A wheel assembly for supporting a load bearing platform includes a primary wheel and at least four secondary wheels that are of equal size. The primary wheel includes at least one planar member having an even number of axles at fixed locations extending perpendicularly therefrom with one secondary wheel mounted on each axle. The fixed locations are angularly equidistant apart and also equidistant from the central axis of the primary wheel. The diameter of each secondary wheel is greater than is the distance between locations, and adjacent secondary wheels are arranged to roll in separate, parallel paths.

Abstract: A process for the destruction of vesicants, nerve agents, and related chemical compounds is described. Blister-type chemical agents such as lewisite and mustards, as well as G or V Class nerve agents and phosphorus-containing pesticides, are reacted with a neutralent solution of a persulfate, preferably potassium peroxymonosulfate, and a peroxide, preferably hydrogen peroxide, at temperatures ranging from ambient to boiling for a time sufficient to reduce the residual agent concentration to levels acceptable for disposal in a routine manner.

Abstract: A timer for delaying the operation of a toggle switch for a pre-set interval includes a mechanical, spring powered timer which drives a cam that engages the toggle of a conventional wall switch to move the toggle from one position to another. The timer is contained within a housing which, in turn, detachably connects to a housing floor that is mounted over the toggle switch cover plate.

Abstract: A system for teaching basic arithmetic facts to students and for measuring their progress and rating their knowledge using a computer program that provides repetitive practice and immediate positive reinforcement is provided. The system features structured practice using problem sets of progressing levels of difficulty with problems selected randomly from each set. Progress made by individual students is tracked by generating a proficiency rating that reflects the arithmetic function tested, the level of difficulty of the problems presented, and the percentage of correct answers provided within a preset time period. Summary reports are generated and displayed at the end of each session as are the proficiency ratings.

Abstract: A system for the collection of near real time confirmation samples is provided to quickly eliminate false positive alarms by confirming the presence or absence of a chemical agent when a monitor operating in near real time to detect the presence of that chemical agent generates an alarm. The confirmation sampling system is synchronized with the near real time monitor and the confirmation sampler and monitor draw common samples of the atmosphere of concern. In the event that the monitor generates an alarm, the confirmation sampler preserves the sample taken contemporaneously with the alarm event for separate analysis, and also takes and preserves one or more follow-on samples.

Abstract: A printed circuit fluxgate sensor for use in magnetic gradient detection devices and the like includes a highly magnetically saturable core formed as a flat, closed loop that is bonded between two planar substrate members. An excitation coil is formed on the outer surfaces of the substrate members by masking and etching a layer of a conductive metal in a pattern of tracks that extend across the core. Each track end is connected through a metal plated bore hole through the substrates from one track end to the next adjacent track end on the opposite substrate to form a current path circling the core in a toroidal fashion. Indicia are provided on the sensor that define the mechanical axis and the magnetic axis of the sensor.

Abstract: A power switching transfer relay is provided to automatically switch an electrical load, such as that drawn by a computer or other sensitive electrical or electronic equipment, from a primary power source to a secondary, or backup, power source upon interruption or loss of the primary source. The transfer relay includes a power relay and two control relays that are arranged to switch the electrical power input from the primary source to the backup source upon failure of the primary power source in the space of less than one cycle, and to actuate an alarm upon loss of the primary power source, loss of the backup power source, or the occurrence of a relay fault.

Abstract: A walker includes a frame with downwardly extending front and rear legs.
