    摘要: The equipment for measuring on earth the thrust of thrusters for use in space comprises a balance (1) and a measuring means (11) which is associated with the balance in order to measure the thrust exerted by the thruster (P). The balance (1) is provided with a target (13) at which the exhaust jet from the thruster (P) is directed, whereas the thruster is mechanically free from the structure of the balance and the measuring means (11) measures the force applied to the balance in order to balance the thrust exerted on the balance by the jet from the thruster.

    摘要: A process for the fabrication of thermistors is described. Conductive wires are positioned in a spaced fashion and are aligned so as to intersect one another. The wires are maintained in the above alignment and placed into a reaction chamber or other suitable environment in which chemical vapor deposition of a semiconductor material by a pyrolysis technique is produced. The temperature of the reaction chamber is preferably just below the temperature level needed to produce the vapor deposition. Electric current is preferably passed through the conductors causing them to heat at the region of the intersections to a level sufficient to induce vapor deposition. The semiconductor material is caused to be deposited upon the conductors in the region of the intersection and is continued until the semiconductor material substantially completely surrounds both of the wires in the region of the intersection so as to mechanically and electrically join the wires. The growth is continued until the thermistor of the desired characteristics is developed. Thereafter, two adjacent leads are removed leaving the remaining two leads projecting from the semiconductor material for use in coupling the thermistor to electrical circuits. The process when completed substantially provides a thermistor device which is ready for use without the need for performing additional steps of providing electrical terminations. The nature of the process also lends itself advantageously for producing thermistors on a large mass production scale.

    摘要: A sterilization system for PET containers and bottles including at least one electron flow generator 1, a scan gun 2 and at least one target 4 preferably made of heavy metal, so that when a part of the electron radiation hits said target a reflected X ray radiation is generated, which contributes to the sterilization of the containers. A certain amount of liquid or gaseous oxygen which upon collision with the electron radiation is converted to ozone is also exposed to the radiation, thus further contributing to the sterilization.

    摘要: The cathode of an electron gun is connected to the body of a space vehicle, performing an automatic limitation (or neutralization) of the negative potential (measured with respect to the physical entity toward which the electron beam is directed, i.e. the anode (A) of the gun, whether this be the environment in which the gun is immersed or a particular object such as a second space vehicle) which the body may assume in the absence of the connection referred to. The aforementioned negative potential is limited or neutralized by means of the extraction of negative charges emitted from the gun (K-E) in the form of an electron beam under appropriate conditions of vacuum. The gun comprises a cathode (K) to be connected to the body (C), at least one accelerating electrode (E), an accelerating voltage generator (G) and a generator (R) for heating the cathode.

    摘要: An electron gun and a high tension switch permits the achievement of high-power electron beams which are ON-OFF modulated by DC up to frequencies exceeding kHz. The electron gun has a cathode, at least two accelerating electrodes, a cathode heater, and a possible focussing system. The or each accelerating voltage, generated by any source, which may in the case of space applications also be a tether, is applied between accelerating electrodes and cathode, with the exception of an appropriate accelerating electrode to which there is applied, by of the switch, alternately its accelerating voltage or the same voltage as that of the cathode, obtaining an ON-OFF modulation of the electron beam emitted by the gun.

    摘要: A process and apparatus for increasing the pulse repetition frequency in a laser is disclosed. The laser includes first and second series connected discharge tubes, a supply unit for applying energy to the discharge tubes and a pulse generator for controlling the discharge of the discharge tubes. The discharge tubes are alternately discharged such that one of the tubes is charging as the other of the tubes is discharging. In this manner, the maximum pulse frequency of the laser is twice the maximum pulse repetition frequency of each of the individual discharge tubes.
