The problem with bench pressing is that you may actually exhaust yourself to the point that you can not push the barbell off of you or high enough to place it back on the supports. My design completely eliminates this problem, because the barbell remains within the support structure at all times – refer to the drawing.
Modular Spacecraft Concept:Valkerie
Abstract:
Valkerie is an attempt to create a multi-platform, multi-mission reusable spacecraft that uses gravimetric conditions in space to provide long-range capabilities. It is unique in that its main power source is a series of sequenced mechanical generators which use gravity as a force input and makes the craft in effect self propelling.
INTRODUCTION
Bio-refineries are analogous to petroleum refineries, which produce multiple fuels and products from crude petroleum. By producing multiple products, a bio-refinery takes advantage of the various elements in biomass and their components, maximizing their value.
For example, starch consumed during grain-based ethanol production concentrates protein and other nutrients,
This proposal relates to conceptual design of "valved two stroke engine with extended expansion". In a four stroke engine, power stroke occurs once in a two rotation whereas in a two stroke power stroke occurs once in each rotation. Theoretically a two stroke engine produces double the power of four stroke engine .
Imagine having a ball with an input shaft and an output shaft that you can move to almost any position and still supply a constant power to the output shaft, even while moving.
It's easy to find a 90 degree gearbox. Such a gearbox can be mounted at any angle, but is stationary. Then there is the universal joint.
Variable ratio chain drives (derailleurs) are extremely efficient, but suffer from several problems:
1. They should not be shifted under load.
2. They should not be shifted while stopped.
3. The chain is side loaded for most gear combinations, limiting the useful combinations.
4. They are subject to jamming caused by the chain wedging between the gears.
Autonomous Velocity Motors
One of the biggest problems with any device that needs an electric motor is the faster a motor turns and the more torque that is required, the more current and/or voltage is required to run it which limits the time a motor can run from a stored energy source like a battery.
This invention deals with an electronically controllable Variable Valve Lift System for internal combustion engines.
This system is a mechanical transmission having the capability of varying the lift of the intake and/or exhaust poppet valves while the engine is running and when varying its working conditions. Said variations being continuous and within wide limits.
The mechanical transmission includes (see Fig.
Problem: It is estimated that speed is a factor in 1/3 of fatal vehicle accidents. It is my belief that thousands of lives could be saved every year by encouraging drivers to drive within the posted speed limit.
This device would complement current global positioning system (GPS) privately owned vehicle trackers which are sold to anyone who wants to map out a destination or is lost. The device would actually simultaneously transmit a GPS navigation broadcast signal to installed receptors along major highways and roads througout the U.S.
