The navigatorscope can be defined as a smart navigating wire with optical capabilities to inspect difficult-to-access-to areas in medium and large size pipes. The navigatorscope design resembles a flexible borescope. The body of the navigatorscope is made of rubber having a density of 1100 Kg/m3 and a young modulus of elasticity of around 10MPa, this was 40% higher than a rubber compound found. The navigatorscope would be made of 14 segmented links, where each link could be flexed individually. A proposed design with dimensions of each link is shown in figure 1 and 2.

The PZT elements used were of the type EC-65 having a modulus of elasticity of about 60 GPa, a density of 5600 Kg/m3, ...

The modern vehicles operate with lead-acid batteries, which are not environmentally correct, beyond the fact that they are expensive and have toxic products (sulfuric acid and the lead itself). In this work, a new idea is proposed in order to replace such electrochemical systems with new compounds. This new type of battery would be an aluminum-copper battery. This system has several advantages when compared with the classical lead-acid batteries:

1. Aluminum is a fully recyclable metal. The idea here is to use it from renewable sources and materials already existent, as per example: cans, electronic components wasted, etc., without being necessary to produce more aluminum from their ores, by saving energy and natural resources.
2. Copper is also ...

The proposal relates to a non-radiation technology of manufacturing nano- and micro-track membranes by deep penetration. A track membrane is a thin polymer film with through pores which are formed by penetrating a special substance into and through the material of a polymer plate and then removing the traces of penetrated particles from the matrix material thus forming pores. The track membrane may find use in various fields of industry as conventional membrane filters for purification of liquid substances from solid contaminants, e.g. as dialysis filter or water purification.

The new technology provides 5-10 multiple reduction of cost of the membranes and does not require the use of radiation and toxic solvents.

The technology is carried out ...

This device attacks the age old problem of friction, while expanding the range of motion, raising efficiency, and offering virtually unlimited life. It is the first spiral magnetic bearing; making a non-contacting screw thread. A few parts have the functionality of a multi-stage gear train. The size and parts reduction lowers the cost while improving performance and controllability.

Gear reducers, especially long-life reversible types, are found in all types of machinery and automobiles, from window actuators to power steering and automation. Dozens of high precision reliable devices are used as mirror segment actuators in the Webb telescope being built for NASA and non-contacting devices are ideal for 'cleanroom' facilities making semiconductors or pharmaceuticals. How this rotary to linear device ...

The 700 cotton ginners currently in operation in the United States struggle with international competition and declining profitability. This is in part due to the 2000 installed gin stands that use an old ginning technology that produces inferior fiber quality, short length and excessive waste. The World Cotton Economic Outlook projected world consumption to rise 7% to 25.5 million tons, representing a $31.4 B market, while world cotton production is estimated to decline almost 6% to 24.7 million tons. The imbalance of supply and demand is forecast to widen due to the decline in planted hectares and the decline in worldwide cotton yield per acre. These declines in cultivated area and yield pose reliability issues for the downstream textiles ...

Name of invention: Concave and Convex Roller Bearing

Range of field areas: Invention is widely used in the sphere of bearing production, mechanical engineering, as well as aircraft and high and light industry including other related fields of production.

Function: It is to enable the inner and outer rings of a bearing to be rotated smoothly on its axes.

Overview
The invention consists of inner and outer rings as well as cage and rollers. According to the main feature of the scheme the view is that no change is applied to parameters - “D” diameter, “L” length and “P” pressure (stress) of any existing flat cylindrical roller bearing.

It has three parts: middle (center - AMB arc) part ...

This technology provides solutions to current energy problems and can reduce consumption of natural resources.

As an example of the phase transition, there is a phase transition between superfluid state and normal-fluid state of liquid helium. Figure 1 shows the phase transition engine to get energy using the superfluid phase transition. Figure 2 shows the potential energy diagram explaining input and output energy of liquid helium. Vertical axis indicates potential energy of helium. Horizontal axis indicates temperature of helium.

Liquid helium becomes superfluid state at temperature below 2.17K. Temperature environment below 2.17K can be produced on the earth. Also, temperature environment below 2.17K occurs in natural world. For example, temperature of Boomerang Nebula is about 1K. Under such environments, ...

Pauling et al. (1949) used electrophoresis to identify structural differences between normal and sickle hemoglobin. Their findings gave rise to molecular genetics and orthomolecular medicine.

The discoveries of HIV, AIDS and their consequences introduced needs for rigorous studies of functional molecular differences. For example, early findings of co-morbidities with Kaposi sarcoma and acid-labile ?-interferon in clinical laboratory reports of persons with HIV/AIDS provided intriguing clues of “autotoxicity,” “autovirulence” and “context-specificity” (Figure 1; Smith, 1984; Smith et al., 1984a; Smith et al., 1984b). Whereas autotoxicity subsumes all prion processes (cf. Prusiner, 2012), autovirulence introduced a need to investigate novel, de novo and aberrant transcription and translation epigenetic byproducts (GERRs).

Many GERRs may be caused by transmissible and infectious small RNAs ...

This project proposes the development of a Production Logging Electron Spin Resonance Probe to operate in the range of temperatures and pressures found in the crude oil production wells able to provide the surface equipment a real time chemical analysis of the crude collected by each geological layer or depth and logging the proportion corresponding to each of the depths.

The Electron Spin Resonance chemical analysis technique measures the presence of unpaired electrons in materials by excited them through a magnetic field, the measure is made by registering the absorption of certain microwaves frequencies where the samples are located. The ESR is in use since time ago for the analysis of underground soils to determine it potential for crude ...

Stress Corrosion Cracking (SCC) is a sudden and difficult-to-predict severe degradation mode of failure of nuclear, petrochemical, and other industries. This is a development proposal for a very important model´s improvement. This is the slip-step dissolution and film rupture model, developed by Ford and Andresen [1] at GE Research and Development Laboratories, and consolidated in a Code named PLEDGE. The main result of this Code is to predict failures within an adequate regression. But there are some critics about this model [2]. One intends to propose a specific theoretical improvement based in two of Gutman´s (one of the critics of the model) references [3], [4]. The main result is a theoretical improvement for the model which could be improve ...
