    Abstract: A starter for a fluorescent lamp comrises: a gas discharge tube with two external connections which are connected to two electrodes which are received in this gas discharge tube and at least one of which comprises a bimetallic strip, which bends in the direction of the other electrode when there is sufficient heating and can thus make electrically conducting contact therewith; a capacitor connected to said external connections; which starter is intended to form part of a collective electric circuit with the fluorescent lamp, which circuit comprises: two alternating current mains connections, the fluorescent lamp, the starter and a substantially reactive ballast, for instance a self-induction, which ballast is arranged in series between a mains connection and the lamp, which starter is connected in parallel to the lamp and which two mains connections are connected to respectively the ballast and a lamp electrode on the end of the lamp remote from the ballast; and has a feature that the capacitor has a value of a minimum of 5 nF.

    Abstract: Examples of a jet control device are described. The jet control device can comprise a jet deflecting member that is configured to intercept and/or collide with a high speed jet emerging from a jet formation location. The interaction of the jet deflecting member and the jet can cause the high speed jet to be dispersed into a plurality of jets with a number of flow directions which may be sideways to an initial direction of the high speed jet. In one embodiment the deflecting member can include a liquid guide formed by injecting a fluid out of an outlet nozzle so that the liquid guide extends longitudinally away from the outlet nozzle. In another embodiment the deflecting member can include an array of solid pellets injected through an outlet in a direction of the emerging high speed jet and configured to collide with the emerging jet thereby deflecting its initial direction.

    Abstract: A fast-closing valve system has been provided which operates to protect a cyclotron from loss of vacuum and backwash of radioactive contamination when using intensely alpha-active actinide targets. The valve portion consists of a valve chamber adapted for mounting in a beam tube and having aligned ports on opposite sides through which the accelerated particle beam travels. A valve gate is slidably mounted in the valve chamber between the ports and normally urged into a seated position, closing the ports, by means of compression springs. The valve gate is held open by means of an electromagnet and, when the current to the electromagnet is suddenly shorted, the magnetic field rapidly collapses and the springs slam the valve gate into the seated position. The circuit controlling the actuation of the electromagnet uses a spark plug as a pressure sensor mounted in the beam tube, downstream of the valve and when a slight pressure rise in the beam tube occurs the spark plug fires triggering the control circuit which, in turn, shorts the electromagnet. A plurality of annular baffles are mounted in the beam tube to retard the shock wave from pressurized gas backwash in the case of an accident, such as a target rupture, allowing the valve to close before the gas reaches the valve assembly.
