The patent pending RSK-185 is a lithium-ion battery powered rotary tool to safely remove the criss-crossed outer layers made of high strength spring steel on umbilical cables. These cables are used to control and power ROV vehicles (remotely operated underwater vehicles). Previously the only way to cut these cables was to use a rotary hand grinder; this method is very labor intensive and could take hours, each steel strand had to be individually cut.
The RSK-185 cutting depth stop is easy to set which eliminates the operator worries of damaging the cable’s core. The outer steel armor must be removed while preventing damage to the cable’s inner core which contains the electrical conductors and fiber optic cables. A specially ...
This prototype is a new type of telescope dedicated to a non-professional amateur public. This system is composed of a fully automated rotary movement and an inclination automatic. These two movements are controlled by two stepping motors by means of a kit electronic control. Motor commands are fully guided them through a second circuit board composed of a computer system, giving a 32-bit RISC ARM11 MCU, memory, SDCARD, VGA to an LCD, HD-output CCD camera, a GPS 3D, may be added a wireless system and an external control software. Part of the goal to a slope of 2 ° cone which will allow an accumulation of higher brightness, the diameter of the mirror is quite big 400 mm diameter. ...
Magnetic assemblies, for switching power excitation, using Sector Torus Core sections, in conjunction with round rod core sections,and two layer coherent windings, can weigh half as much, cost half as much, and have half the energy losses, when compared to assemblies in current production. Typical magnetic assemblies include Inductors, Coupled Inductors, Transformers, Motors, Generators, Motor-Generators and Actuators.
The lower core losses are produced by operating at much the same frequency and flux level, generating much the same specific loss, but multiplying the specific loss, by less than half the volume, when compared to ordinary ferrite shapes, or ordinary core shapes for motors or generators.
The lower copper losses are from being able to use larger wire, without increasing layer ...
Bushing bearings are used as a cost effective alternative to much more expensive ball or roller bearings. The main drawback, however, is the radial clearance between the bearing and the shaft that continues to increase as the bearing wears. In addition to the noise generated, especially in a reciprocating motion application, there is a critical maximum clearance where the lubrication breaks down resulting in damage to the shaft as well as the bearing. The self-adjusting bushing bearing (SABB) design eliminates this failure mode and provides additional benefits that make it a more advantageous and cost effective alternative to ball, roller, as well as conventional bushing bearings.
Figures 1, 2, and 3 show an exploded view, partially assembled view, and ...
In most gear drives, due to inertial motion the driven output shaft becomes the driving one and the driving input shaft becomes the driven one. This condition is known as back-driving. In order to prevent this condition, different types of brake or clutch devices are used. However, there are also solutions in gear transmission that prevent inertial motion or back-driving using self-locking gears without any additional devices. The most common one is the self-locking worm gear with a low lead angle. However, worm gears has some limitations: very low gear mesh efficiency, relatively high gear ratio, the crossed axis shafts’ arrangement, low speed, or increased heat generation.
The proposed new self-locking gear actuators don't have such application limitations. They ...
Many alloys have rare earth additions to improve their surface properties at high temperatures. A new product, Minimox® Nanocrystalline Alloy Treatment, exploits this fact to protect a variety of alloys in extreme environmental conditions of elevated temperature and/or corrosive atmospheres. Thermal oxides that form after this treatment are different in structure and/or chemistry from the thermal oxides that form without pretreatment. The ultimate protective oxide is primarily a function of the alloy itself, not the rare earth material (Figure 1). In this way, the treatment helps the alloy become self-protective. The technology allows economical surface modification in the field and inside complex geometries using low concentrations of rare earth materials in a water-based solution.
Because Minimox® treatment ...
Steam Generating Apparatus (SGA) is a small, compact hot water or steam generator using a small motor to spin up to speed for whatever you require.
The SGA device is only 4" in diameter using an AC drive to control a 1HP motor. The system would include a micro processor to set up and tweak your specific application. SGA can replace hot water heaters, hot-water space heaters, swimming pool heaters, and hot tub heaters.
The SGA is harnessing the power of both the water hammer effect, as well as cavitation to produce hot water and or steam.
The SGA is Green and Energy friendly, operating at 99.999% efficiency. It utilizes only renewable and recyclable ...
Simultaneous Production of Nano Carbon, Hydrogen and Energy
This process is based on compression of acetylene. When acetylene is compressed it explodes, generating thermal and mechanical energy and decomposes to its original constituents; carbon (finely divided) and hydrogen.
The scope of work includes full process and mechanical design for a system that can produce nano carbon, and hydrogen; separate the produced carbon and hydrogen; and utilize the thermal and mechanical energy.
This effort will include:
1. The selection of the appropriate acetylene generator (Carbide-type is one of the options).
2. Develop design specification for the appropriate compression/expansion device.
3. Design, develop and select the means with which to recover the explosive wave and thermal energy.
This telescope design consists of a primary mirror shaped to a parabola along a single axis. Whereas a conventional telescope focuses light to a single point, the Single-Axis Telescope spreads its focus along a sensor the same width as the mirror.
I call this a scanning telescope because it is designed to be stationary, using the rotation of the Earth as its scanning mechanism.
This design has four major advantages over conventional prime focus CCD reflector telescopes.
The elongated sensor (CCD) greatly improves heat dissipation, allowing for much faster capture rates and less thermal noise.
Conventional telescopes use motors on an equatorial mount to track areas of the sky. A wider sensor with faster frame rates ...
Chemical classification is an important operation for many industries. Typically, this is done with portable spectrometers that cost on the order of $5000. The data from portable spectrometers must be transported back to the lab to have post processing determine what the contents of the measurement were. The complexity of these spectrometers is often excessive; the expensive scientific grade accuracy instruments are useful for separating every single chemical known to man, but in the cases where only two classes are needed (clean air vs. anthrax in air), a wider network of less expensive instruments programmed specifically for this detection task will be more suitable.
Smartphones natively contain almost all of the components required for spectroscopic material distinction, and many ...
