Abstract: A method, device and system employs particles, such as nanoparticles, and an electric or electro-magnetic field, to cause cell death in target cells by non-thermal means. The method of causing targeted cell death comprises the steps of: introducing a particle to the interior of a target cell and exposing the target cell to a transient electromagnetic field for a sufficient time interval in order to cause cell death. Apparatus for performing the method; as well as techniques of delivering particles and for producing particles are also described.

Abstract: A method, device and system employs particles, such as nanoparticles, and an electric or electro-magnetic field, to cause cell death in target cells by non-thermal means. The method of causing targeted cell death comprises the steps of: introducing a particle to the interior of a target cell and exposing the target cell to a transient electromagnetic field for a sufficient time interval in order to cause cell death. The invention overcomes problems associated with similar methods as a result of the fact that a smaller electric field is applied because the particle enhances the effect of the electric field in its immediate vicinity, so reducing the field strength needed to achieve cell lysis and thereby reducing the risk of damage to healthy cells that may be in its vicinity. Apparatus for performing the method; as well as techniques of delivering particles and for producing particles are also described.

Abstract: A stacking device for assembling a slack of uniformly sized articles 1, has a receiving station for successively receiving said articles 1, and a lifting means to raise said articles from the receiving station to a stacking station The stacking station includes catching means 3 to catch and retain the articles in the stacking station, the catching means comprising at least two catchers 3 located on opposite sides of the station to engage opposite side edges of the article. The article 1 when being raised contacts the catchers 3 to displace the catchers to a closed position to enable the article to override the catchers 3 to move to a position above the catchers 3, the catchers 3 having biassing means to bias the catchers 3 back to an open position to engage and support the article 1 in the stacking station when the lifting means is withdrawn. The catchers 3 have a uniform cross-section and are pivotally mounted in a frame member 5 having a uniform cross-section.

Abstract: A clamshell type device which is adapted for use in strain relief. The clamshell surrounds the wire and also surrounds at least a part of the connector that attaches to the wire. The clamshell may press against the connector to hold to the connector and also may press against the wire. This provides strain relief. The outer surface of the clamshell device includes a part that still allows depression of the release mechanism from the connector.

Abstract: A dual voltage connector having keyway portions enabling protection of the connector against unintentionally using it with a long voltage. A higher voltage version of the connector, which supplies the voltage, is protected. In a female version of the connector, a plug is placed in the higher voltage portion of the connector.

Abstract: A fluid driven reciprocating pump is described, particularly for use in feeding fertilizer solution to an irrigating water line, the pump being driven solely by the pressurized water in the supply line and requiring no electricity or other power source for either driving or controlling the pump. The described pump includes a pair of flexible diaphragms defining a pair of expansible chambers, and a reciprocating rod connecting the diaphragms to each other so that they move in unison. A main valve supplies pressurized water to the expansible chambers, and a pilot valve controlled by operator elements carried by the reciprocating rod controls the main valve connections to the pair of expansible chambers such as to effect an expansion and contraction of the chambers.
