| 4598348 | Arc lamp support system The anode of an arc lamp is supported on an arm. When the arc lamp fails, motion of the arm detects the failure and turns the current off of the arc lamp. In addition, after failure of the lamp, the arm limits motion of the anode so that it does not strik... | 07/01/1986 |
| 4591753 | Electron beam apparatus comprising a wire source An electron beam apparatus comprises an electron source with an electron emitter in the form of a wire, suitably of metal, which slides on two supports. The two supports are constructed and spaced apart at such a distance (not more than 1 millimeter) that... | 05/27/1986 |
| 4194120 | Adjustable ionization chamber An ionization chamber with two electrodes having a variable spacing and with a radioactive source for the ionization of the electrode gap therebetween includes an adjusting mechanism for the positional adjustment of one of the electrodes relative to the o... | 03/18/1980 |
| 4189644 | Smoke detector ionization chamber An ionization chamber of the type used in an ionization smoke detector is made adjustable. The chamber has two electrodes and one radioactive source for ionizing the electrode gap. One of the electrodes is laterally displaceable relative to the other. As ... | 02/19/1980 |
| 4188559 | Rotary anode X-ray tube A rotary anode X-ray tube capable of operating at very high voltages of several hundred thousand volts.
