The “Pillow Purifier”© is a semi-automated device for cleaning and sanitizing pillows. Bacteria, viruses, dead skin, saliva, oils, hair chemicals, fungi, dust mites and their feces, are among the common items found on the surface and within pillows when a guest is spending the night in a hotel. On rare occasions even lice or fleas. Even though pillow cases are cleaned, the pillow itself gets contaminated. High quality pillow covers that could prevent internal pillow infestation are costly, uncomfortable and can still harbor surface organisms.

“The National Library of Medicine recommends replacing pillows every three years… a major cause of allergies and upper respiratory infections. Cleaning them is nearly impossible since fibers break down, mat up and, over time, ...

The pneumatic pump proposed below comprises 1) Air Controller, 2) The Pumps, & 3) Hose Connections.

The pumps (Part no.1&2) are simply cylindrical hollow containers. They do not have conventional rotating or reciprocating components like an impeller, piston, bearing etc. They are connected to check valves (foot valves) 4,4.1, 5, 5.1. as shown in the figure and submerged in the well 3. Air source 9 is connected to a 5 Port, 2 Position, Solenoid by spring return Directional Control valve 15 through an electrically operated isolation valve 10. The solenoid of the DC valve is connected to electrical power supply 19 through a switch, timer 11. The water from well 3 is pumped to an over head tank 18 as ...

Recreational vessels (RVs) are often serviced in boat yards. It is very common to see boat yards with a very limited infrastructure to support an efficient workflow. In fact, some of the boat yards have challenging conditions, sometimes unsafe for workers and customers. These challenging conditions reduce the quality of the service and ultimately increase the cost of the operation.

Over 90% of inland waterways (IW) have no access to boat yards or service facilities within a distance of 10 miles. High property values in the surroundings of IW limit the options for boat owners when they have to service their boats. Vessels over 28 ft are costly to remove from the water and transport for servicing.

Between two railway rails there must be a thermal space gap to accommodate the steel track thermal expansion due to environment temperature change. When a railway car’s wheel passes this gap, it causes impact between wheel and track and causes vibration. It also causes material fatigue, equipment wear, and energy losses. What is worse, due to the weight of the car, when the wheel approaches the gap, the first rail will sink and causes an uneven connection which causes more damage. This phenomenon becomes more important for high speed trains. Here I proposal a simple solution. To make the two rails’ connect surface to have an angle so that before the wheel leaves the first rail, it already lands on ...

This proposal provides a CAD driven Robotic Application for Sprayfoam/ShotCrete for the construction of various sizes of residential Monolithic Dome Buildings. The intent is to provide via Computer Aided Design a Controller interface to automate the construction process. The Robotic arm would be fitted with a sprayfoam/shotcrete nozzle on the end effector and the spraying action controlled via a computer program which drives the Robotic Arm Controller and the action of the Robotic Arm rapidly and consistently creates the Monolithic Dome Building via the CAD. Features such as Door and Window openings would be automatically provided for during the spraying operation and this gives an accuracy and consistency in the building process enhancing quality in the end product.

The three most popular hand tools used by the human race are the hammer, screw driver and ratchet wrench. Sales for these tools increase annually due to their universal appeal and usefulness. Tool sales in 2010 were $15.5B in the US and $43B worldwide according to the Freedonia Report on Power and Hand Tools.

The ratchet is the ideal tool for torqueing or removing a fastener and saves a great deal of time and labor. Current ratchet technology relies on a system of gears to rotate in either direction and allows the tool to remain in contact with the fastener between successive turns. All of which is a big improvement compared to its predecessor, the box wrench.

Conversely, the ...

The invention relates to some rotary valves for heat engines, pumps and compressors to replace known valves – with go forth alternative motion - from existing engines, pumps and compressors, and all installations and devices that can benefit from this solution.
The rotary valve comprises a valve block, generally made of light alloys or ceramic material made by means of known technology, shaped corresponding to its purpose and the ends are provided with one or two bearings and a drive shaft. The body of the valve consists of a metal or ceramic disc with one or more fluid flow holes and a shaft for coupling the drive shaft.

It is here where a cycle occurs every half rotation axis, ...

The Patent Pending rotary cutting Roto-Skinner RSK-185 was designed especially for armored umbilical cables used on underwater Remotely Operated Vehicles (ROVs). The same tool can also have applications for cables subject to great stress, such as oceanography research or mining operations.

These cables usually are constructed with outer steel strands made of high strength steel wires. To make an electrical or fiber optic connection several feet of these multiple strands must be removed. This operation can be performed with hand tools. However, because of the large number of wires to be cut, it is extremely time-consuming and great caution must be taken to prevent damage to the cable core.

This cordless cutting tool is powered by 18V lithium-ion batteries. ...

CatOne
Rudder-less Autonomous Unmanned Surface Vessel

In order to be actually autonomous, small unmanned surface vessels need to avoid getting caught by floating objects (algae, plastic bags etc.). CatOne is a family of multi-purpose catamaran-robots aimed at performing, in total autonomy or under remote control, a large spread of missions. They are proposed either as an alternative to boats with onboard drivers/operators or as a replacement/complement of networks of non-garrisoned, measurement fixed stations.

One of the main peculiarities of these (patented) tools is the electrical propulsion/guidance system, based on two aerial propellers, the only moving components of the system. Neither propellers nor rudders protrude under the (catamaran) hulls, allowing operations in very shallow water, in presence of algae and ...

This system is consists of a fly wheel and a pulley connected together by a belt. As the fly wheel stores energy, it will increase the torque of motor. The fly wheel is powered by an electric motor. The wheel drives the pulley that is connected to an electric generator. A part of the electricity generated will be transferred back to the motor (driving the wheel) and the remaining power can be used to operate any ...
