Patent GB-2422566-A (GB)
Title: Abrasive entrainment
Inventor: MILLER DONALD STUART
IPC: B24C5/02
Filed: 2004-11-15
Abstract: A method for generating a high-velocity cutting jet(3) comprises forming a high velocity jet (10) of a liquid such as water, forming a suspension of an abrasive such as garnet in a carrier gas containing a condensable vapour such as superheated steam, and entraining the abrasive suspension into the liquid jet (10) so that the vapour condenses, producing a cutting jet (3) of a liquid/abrasive mixture. A cutting head (7) of apparatus for generating the cutting jet (3) has a chamber (8) into which the abrasive suspension is passed. The liquid jet (10) traverses this chamber (8), entraining the suspension, and passes into a tapering transition region (5) and a bore (9) of a nozzle (4). Kinetic energy is transferred from the liquid jet (10) to the abrasive as they pass through the chamber (8) and the nozzle (4). Condensation of the vapour ensures that the cutting jet (3) leaves the nozzle (4) at close to ambient pressure, reducing the diameter of the cutting jet (3) compared to conventional abrasive-in-air systems, so as to increase the energy density of the abrasive.

Title: Limiter integrated circuit
Inventor: NICHOLSON DEAN
IPC: H02H9/04
Filed: 2006-05-24
Abstract: An integrated circuit 100 comprises a limiter section 105 between a radio frequency (RF) input port 134 and RF output port 136, and a detector section 102 that detects a power level or an electrostatic discharge (ESD) event of an input signal and is coupled to the limiter section. A limiter drive circuit 147 may comprise a differential amplifier 160 which, when the signals from the detector outputs 139, 141 indicate an electrical overstress, switches limiter diodes 104-118 to a forward-biased low impedance condition so that most of an incoming signal is reflected by limiter section 105. Resistors 150, 152 may cooperate with voltage divider resistors 142, 144 to set the operating points, and enabling rapid switching, of detector diodes 138, 140, so that negligible distortion is added to the incoming signal at an un-attenuated power level. The integrated circuit may comprise a gallium-arsenide (GaAs) integrated circuit and differential amplifier 160 may be a silicon device or a GaAs device on the same chip (fig 1B, 172). An integrated amplifier (fig 2, 202) may precede the detector section (fig 2, 204) and may be a hetrojunction bipolar transistor (HBT) and the limiter drive circuit may comprise a comparator (fig 2, 260). A detector output (fig 3, DETout) may provide overpower indication. The limiter may comprise a directional device (fig 4, 401) such as a directional coupler or bridge, which can prevent power from the limiter being reflected toward the detector (fig 4, 404).

By providing a specific portion of the front panel with this feature, access can easily be obtained to the baby's umbilical stump, but without substantially weakening the remainder of the envelope, and with reduced risk of injury to the baby.

Filed: 2006-09-22
Abstract: An atomic beam optical frequency atomic clock and a producing method thereof includes an atomic oven (1) provided in a vacuum chamber (2) which sprays an atomic beam (8) from a fire hole after heating, a transition laser (4) corresponding to the frequency of the transition excites the atomic beam (8) from a basic state of the transition to an excited state of the transition which passes by means of insulating, and the atomic beam (8) acts with the laser which corresponds to the frequency of the transition. After acting, the atomic beam passes a signal detection region which has a detection laser (5) and acts with the detection laser (5). After acting, each atom emits spontaneous radiating photons, and the fluorescent photon signals which are excited by the detection laser (5) are detected, and the transition laser (4) which is used to detect the frequency of the atomic transition is modulated and the frequency of the transition laser is locked at the transition spectrum of atom by the detected signals, so the atomic clock is realized.

Title: A method of processing a large data file
Inventor: HAYES LEONARD PATRICK
IPC: G06F17/30
Filed: 2008-12-09
Abstract: A method of processing a large data file in a Data Transfer System (DTS), the data file is typically of the order of 0.5 Mb in size and the DTS will handle several thousand large data files every day. Accordingly, the DTS may be required to process several terabytes of data every day. On receipt of a large data file, the DTS creates a DTS message for the file which comprises a header portion and a content portion having the records of the large data file therein. The DTS retrieves a format specification from a local catalogue and then uses it to convert the records in the content portion into a common data file format (CDFF). The data records are processed in CDFF before being reconverted into the originating format for subsequent delivery. The processing time required to process large data files is thereby reduced.
