An Abbe–Koenig prism is a type of reflecting prism, used to invert an image (rotate it by 180°). They are commonly used in binoculars and some telescopes for this purpose. The prism is named after Ernst Abbe and Albert Koenig . The prism is made from two glass prisms, which are optically cemented together to form a symmetric, shallow Vee ...
Rideau Correctional and Treatment Centre. / 44.97361°N 75.82306°W / 44.97361; -75.82306. Rideau Correctional Centre was opened in 1947 as a minimum-security facility, with an integrated farm where inmates could learn skills to be plied upon their release. [1] It was decommissioned in 2004, [2] and subsequently demolished in 2013.

Tronado machine. The Tronado Machine was a device which employed ultra high frequency or microwave radiation as a hyperthermia therapy for cancer; however, tests have failed to back its treatment claims. A man named Tronado designed the machine in the 1970s. The treatment was improved and a new type of machine built by Dr John Holt who was ...
The Therac-25 was designed as a machine controlled by a computer, and some safety mechanisms switched from hardware to software. AECL decided not to duplicate some safety mechanisms. AECL reused modules and code routines from the Therac-20 for the Therac-25. The first prototype of the Therac-25 was built in 1976.
The S-PRISM represents GEH's Generation IV reactor solution to closing the nuclear fuel cycle and is also part of its Advanced Recycling Center (ARC) proposition [1] to U.S. Congress to deal with nuclear waste. [2] S-PRISM is a commercial implementation of the Integral Fast Reactor developed by Argonne National Laboratory between 1984 and 1994.
A Hieronymus machine is any of the patented radionics devices invented by electrical engineer Thomas Galen Hieronymus (21 November 1895 – 21 February 1988). Hieronymus received a U.S. Patent for his invention in 1949, which was described in the patent application title as a device for "detection of emanations from materials and measurement of ...
An Uppendahl prism is an erecting prism, i.e. a special reflection prism that is used to invert an image (rotation by 180°). The erecting system consists of three partial prisms made of optical glass with a high refractive index cemented together to form a symmetric assembly and is [2] used in microscopy as well as in binoculars technology.
