This device is a dispenser for a measured amount of liquid, bleach, water softener, etc., into a toilet tank with each flush. The valve works on the principal of differential densities between water and the valve shuttle. The volume dispensed is the volume of the cavity formed by the valve shuttle and the base of the unit. When the toilet is flushed the water level goes below the level required to float the valve shuttle which lets it drop and dispenses the liquid contained in the valve reservoir. This motion closes the valve inlet with the conical upper end of the valve shuttle. The angle of the cone is designed to shed air bubbles from the now empty valve ...

SnotRocket is a unique syringe-type aspirator that is more powerful, more precisely controllable, more sanitary, more rugged, more convenient and more discreet than any other pediatric nasal aspirator.

The simpler version has only two parts, both injection-molded plastic -- a rocket-shaped outer cylinder and a matching plunger with fin-like finger-grips. A spring-loaded version would require only two more parts, the spring and a snap-on base cap.

Various commonly available thermoplastic polymers that are especially slippery are preferable. If the parts are made to be very close-fitting then no seals are necessary. Otherwise, a stock o-ring can easily be incorporated into the design.

The cylinder is open at both ends. The working end, the tip of the smoothly rounded “nosecone,” gently seats against ...

BikeUp is the main ally of the population, against vehicular traffic in the city of Lima. It seeks to increase the number of people who use bicycles to transport to different places, and for this, within this application you can accumulate "money" according to the number of kilometers traveled by bicycle, which will be called "bi-credits." There will also be a discussion forum, which will help users report accidents or recommended ...

Umbilical Care is an L-shaped silicon cord clip used to test the bacterial infection at baby’s cord. Via the “histamine testing sticker” attached on a hollow chamber of Umbilical Care which can react with the histamine produced by bacteria, medical staff and mothers can deal with cord infection when an orange sad face is shown. It is an efficient way to prevent infection and reduce the staff’s burden. The L-shaped design allows staff to measure the safety distance to chip on, which makes the operation efficient and makes extra room for Umbilical Arterial Catheter operation in the ...

According to the U.S. Department of Transportation 17% of all motor vehicle environmentally related crashes was caused by Glare or blindness from sunlight. Between 2005 and 2007 this accounted for more than 9000 crash accidents in US.

This invention seeks to reduce the risk of sun blindness in five steps.
1. Identify the angle of the sun relative to the vehicle
2. Identify the position of the drivers eyes relative to the Vehicle.
3. Using trigonometry to calculate the position of the sun on the windscreen, as viewed by the driver
4. Position a shading object in the line of sight to the sun, preventing the sun to enter the eyes of the driver
5. Continuously relocated ...
