Hot water reset. Hot water reset, also called outdoor reset (ODR), is an energy-saving automatic control algorithm for heating boilers that are typically fired with fuel oil or natural gas. A hot water reset control loop measures the outside air temperature; this information is used to estimate demand or heating load as the outdoor temperature varies.  The supply hot water temperature is modulated up and down range in an inverse linear ratio to outside air temperature.  The typical range for conventional boilers is to vary the supply water temperature from  as the outside temperature varies from .

Buildings cool down slowly when the outdoor temperature is moderate, and cool more rapidly when the outdoor temperature is colder. Hot water reset reduces the energy output by the heating system to approximately balance it against the energy lost as the building cools. This makes it easier to maintain the temperature within the desired range (as the radiant heating systems that boilers usually power respond slowly and are subject to overshoot) and can allow boilers to operate more efficiently.

Implementation
The control system can be made to modulate the supply water temperature in two different ways:
By acting as an operating control on the boiler burners, either modulated on/off, high/low fire, or fully modulating fire, depending on the burner construction. When modulating the actual boiler temperature lower, water temperature needs to have a low limit and be maintained above the flue gas condensation temperature for non-condensing boilers, typically above . Condensing boilers can be made to operate at temperatures below the flue gas condensation limit, typically below  and raise stated efficiencies from 70-80% to around 90-95%.
By acting as an operating control on a three-way powered mixing valve or proportional injection pump system that modulates the supply distribution hot water temperature. The mixing valve or mixing pump system recirculates the return water temperature and adds proportionally supply hot water from the boiler for tempering to achieve the desired supply water temperature. Another method is to adjust boiler temperature from thermostat activity. This is indoor reset control. It is more responsive to real needs inside the building.

Bus mouse. A bus mouse is a variety of PC computer mouse which is attached to the computer using a specialized interface (originally, the Microsoft InPort interface developed for Microsoft's original mouse product).

In the late 1980s, mice were not integrated with IBM-compatible personal computers, and the specialized bus interface (implemented via an ISA add-in card) was one of two popular ways to connect a mouse; serial interfaces were the other method. In addition to Microsoft, Logitech also made bus mouse interface cards.

When the IBM PS/2 was introduced, it included a motherboard mouse interface which was integrated with the keyboard controller (still called the PS/2 mouse interface long after the PS/2 brand was withdrawn); this fairly quickly drove the bus mouse design out of the marketplace.

The bus mouse lived on in the NEC PC-98 family of personal computers in Japan.

Keith Millis. Keith Dwight Millis (May 20, 1915 – July 6, 1992) was an American metallurgical engineer and inventor of ductile iron.

Keith Millis grew up in Rensselaer, New York and earned his Bachelor of Science in Metallurgical Engineering as a 1938 graduate of Rensselaer Polytechnic Institute. A year later he was conferred a Master of Science degree in Metallurgical Engineering at RPI.

Early in the Second World War, chromium was considered critical to the war effort and experimentation was conducted by Millis to find a substitute. He made his discovery while experimenting with molten iron and magnesium. The original intent was to find another element that would cause all the carbon in the cast iron alloy to be combined as carbide. Magnesium was a known carbide former. Instead, the graphite in the iron formed into spheroidal shapes, and the cast iron had high tensile strength plus it exhibited ductility. Thus was born ductile iron in 1943.

Millis and others at the International Nickel Company (Inco) sought and obtained U.S. patent 2,485,760 on October 25, 1949 for magnesium additions to cast iron that would spheroidize the graphite and dramatically ductilize the material.

As an employee of Inco, Millis worked to promote the use of ductile iron as it began to be used as a commercial material.  He also helped to found the Ductile Iron Society, an organization whose purpose is to promote the production and application of ductile iron castings.

Millis died in 1992.

Legacy
Since his death, the Ductile Iron Society has held the "Keith Millis World Symposium on Ductile Iron", a technical meeting concerning all facets of ductile iron material, processing and applications.  The event has been held approximately every 5 years:

 1993 - Hilton Head Island, SC
 1998 - Hilton Head Island, SC
 2003 - Hilton Head Island, SC
 2008 - Las Vegas, NV
 2013 - Nashville, TN

The most recent symposium was co-sponsored by the American Foundry Society. He was inducted into RPI's alumni hall of fame in 1999. A perpetual international scholarship has been awarded by the Ductile Iron Society Foundry Educational Foundation in Millis's name since 1991.

Violet ray. A violet ray is an antique medical appliance used during the early 20th century to discharge in electrotherapy.  Their construction usually featured a disruptive discharge coil with an interrupter to apply a high voltage, high frequency, low current to the human body for therapeutic purposes.

Overview
Nikola Tesla introduced his first prototype violet ray at the World's Columbian Exposition in 1893. Most of the antique violet rays in the US were produced before the Depression era, and some of the larger US manufacturers of violet rays were Renulife, Fitzgerald, and Fisher.  Companies who manufactured violet ray devices made many other types of electrical appliances as well, e.g. Star Electric, which also manufactured stock ticker machines.  Many of the companies who were able to continue manufacturing violet rays after the Depression stopped making them due to World War II, when they began manufacturing radio coils and other electrical components for the war instead.

A typical violet ray device consisted of an ungrounded, electrical control box that controlled the interrupter and housed the magneto coil, and an attached bakelite or other handle housing which contained the high voltage coil and an insertion port for attachments.  Glass, evacuated tubes of varying shapes and for different therapeutic uses could be inserted into the bakelite handle to apply the resulting current to different parts of the body. 

Violet ray treatments were said to cure everything from lower back pain to carbuncles.  From an antique Master Violet Ray manual c. 1920 comes this treatment advice:

For catarrh, this treatment was directed:

Legal actions

During the 1940s and 1950s, makers of violet ray devices were subjected to numerous lawsuits and multiple actions by the US government including recalls, seizures, forfeitures, and orders to have them destroyed. 

The last manufacturer of violet ray electrotherapy devices in the US was Master Electric. The company was subjected to a 1951 lawsuit in Marion, Indiana, and the devices were seized by the FDA. While their manufacture was prohibited in the US by case law, violet ray electrotherapy devices are still manufactured by companies outside of the US.

Other uses

Jon Burge of the Chicago Police Department, who was dismissed in 1992 following allegations of torture of suspects by Burge and detectives working under him in the 1970s and 1980s, may have used a violet ray.  The violet ray was suggested independently by two museum curators after they were given victims' descriptions of one of the several electrical devices used by Burge.

American clairvoyant Edgar Cayce advocated use of the violet ray in almost 900 of his readings.

Since the 1990s, under the name "violet wand", violet ray devices have more recently become popular as relatively safe electrical stimulation devices for erotic electrostimulation.
