An improved thermophotovoltaic (TPV) n/p/n device is provided. Monolithic Interconnected Modules (MIMs), semiconductor devices converting infrared radiation to electricity, have been developed with improved electrical and optical performance. The structure is an n-type emitter on a p-type base with an n-type lateral conduction layer. The incorporation of a tunnel junction and the reduction in the amount of p-type material used results in negligible parasitic absorption, decreased series resistance, increased voltage and increased active area. The novel use of a tunnel junction results in the potential for a TPV device with efficiency greater than 24%.

A computer implemented information extraction process that locates and identifies eddy current signal features in digital point-ordered signals, said signals representing data from inspection of test materials, by enhancing the signal features relative to signal noise, detecting features of the signals, verifying the location of the signal features that can be known in advance, and outputting information about the identity and location of all detected signal features.

Patent for

Patent for "improvements in folding bows for vehicle-tops...for removably mounting the top upon the body of the vehicle" (lines 5-22) including illustrations.

Patent for improvements to a hame-fastener, specifically related to an easily made, inexpensively produced locking mechanism, including illustration.

Patent for an incubator that automatically maintains at least a minimum temperature, with the option to set and maintain a higher temperature, with adjustment of temperature from outside the incubator. The incubator uses electric heat.

Patent for an improved pipe gripping mechanism which engages the interior of a pipe or tube.

Patent for improvement of rail-chairs that would prevent railroad rails from spreading out and allowing for a better connection by a system of rods. The rods would allow for a shorter distance between the middle of the rail chairs and the mechanism allows for better usability.

Patent for a machine to remove the tops of beets while they are still in the ground "without packing or injuring the beets and without removing more or less than the exact portion required" (lines 15-18).

Patent for a car mover designed to move train cars along the tracks and sidings. Illustrations included.

Patent for a bottle for shoe polish which can also be used as a stopper and dauber. Illustrations included.

Patent for a seed hopper "constructed to efficiently receive and discharge the cotton seed" (lines 12-13). Illustrations included.

Patent for a baling press. This invention combines a truck and horse that facilitates the pressing of hay.

Patent for a combined cultivator and harrow. "This invention relates to an improved agricultural implement comprising in its construction a cultivator and a harrow, the tooth elements of which are so constructed and supported by the frame as to be capable of being adjusted for operation in several different positions" (line 8-14) illustration included.

Patent for a Jack. This design is operated by fluid pressure for use with driving axles and wheels.

Patent for a railway tie designed to to provide a metallic tie which is light strong, and durable (line 16-17) illustration included.

Patent for a spectacle holder. Illustration included.

Patent for a telephone transmitter and receiver. The device is for lines "known as 'long-distance' telephones for the purpose of taking up the weakened vibrations and re-energizing them...transmitting them with increased volume" (line 12-15) illustration included.

Patent for "an Alarm Attachment for Electric Bells." "The object in view is the provision of means for facilitating the change of an ordinary door-bell into a continuously-ringing alarm apparatus, while leaving the mechanism free to be changed back into its former operative condition as a door-bell."(Lines 10-15) Including illustrations and instructions.

Patent for a music-leaf turner to be used on pianos. It can turn pages to the right or left and the pianist need not use their hands. The pianist depresses a pedal with their foot to turn a page.
