摘要:
A gas lift pump apparatus for treating ballast water includes a column through which a liquid medium, such as seawater, may be pumped by gas lift. The apparatus includes a delivery device for delivering a flow of a gas into the liquid medium, and a resonance chamber that generates ultrasonic energy therein by the flow of the gas therethrough. The apparatus is operable to launch the ultrasonic energy into the liquid medium in the column.

An electrical connection device (10) for connecting a multi-core machine cable to another electrical device comprises a body (12) having an end-face with apertures and a plurality of insulating sleeves (22) extending about the apertures and a plurality of core coupling means (26, 28) each being at least in part positioned in a respective sleeve. Each core coupling means is connectable to a respective core (29) of the machine cable and has a first contact surface (14) for connecting to a terminal of another electrical device. The device comprises a plurality of spaced apart earth coupling means (24) which surround at least a portion of respective insulating sleeves. Each earth coupling means is connectable to a respective earth potential layer (31) of the machine cable and has a second contact surface (32) for connecting to an earth-potential terminal of another electrical device so that within the electrical connection device the core coupling means are earth-potential screened from one another.

The present invention relates to a hematology instrument system that discriminates platelets from red blood cells, debris and other particles within a blood sample. The instrument system uses an optical trigger and collects data at optical sensor locations relative to a flow cell-illuminating laser beam's optical axis. An axial sensor measures axial light loss due to a particle in the flow cell's illumination aperture. In addition, the instrument system can include an RF unit generates electrical parameters, such as DC and RF parameters, within the flow cell. Blood specimens can be prepared with and without a sphering agent.

The invention provides a method and apparatus for selecting desired attributes for system configuration. The invention uses one or more rule sets to define rules that are met when a configuration is valid. A rule set may specify the interrelation of attribute values within a product or between two or more products. If the combination of attribute values that specify a product conform to at least one rule in each of the rule sets that apply to that product, that combination of attribute values is considered to specify a valid product. If the combination of attribute values that specify all of the products of an assembly conform to at least one rule in each of the rule sets that apply to that assembly, that combination of attribute values is considered to specify a valid assembly.
摘要:
The present invention provides an electrical connection device. The device comprises a pin, socket or lug and a means for electrically connecting the pin, socket or lug to groups of strands of an individual multi-bunch core of a machine, reeling or trailing cable. The means is divided into a plurality of portions and each portion is arranged to receive at least one group of strands wherein, in use, the portions are individually connected to the or each respective group of strands whereby the strength of the connection is improved.

Methods are provided for measurement of nucleated red blood cells in a blood sample. The methods include exposing a blood cell sample to a reagent system to lyse mature red blood cells, subsequently analyzing nucleated red blood cells in a flow cell by axial light loss, DC impedance, and medium angle light scatter measurements; by axial light loss, low angle light scatter, and medium angle light scatter measurements; or by axial light loss, DC impedance, low angle light scatter, and medium angle light scatter measurements; and then differentiating nucleated red blood cells from other cell types by using measured signals and/or functions thereof.
摘要:
An electrical connection device is arranged for connection to a machine cable and includes a pin and a socket. The pin and the socket have engagement surfaces with the pin or socket having another surface that forms a wedging surface for the device. The pin and the socket are moveable relative to each other from a released position to an engaging position in which the engaging surfaces form an electrical contact. The device also includes a wedge portion arranged to impart a force on the wedging surface by contacting the wedging surface on movement to the engaging position. The pin and the socket are arranged so that the engagement surfaces move into opposing relationship on movement to the engaging position and the force imparted on the wedging surface biases one engagement surface against an opposing engagement surface.
