Vacuum component and vacuum apparatus

Номер: GB0002619340A
Автор: PAUL DAVID SMITH [GB], PETER CHARLES LAMB [GB]
Принадлежит:

A vacuum component for a vacuum apparatus, such as a tube 10, comprises a wall element 12 having an outer surface 14 outside the vacuum and an inner surface 16 inside the vacuum, a layer heating element 20, such as a metallic or ceramic resistive heater, connected to the outer surface, and a non-evaporable getter (NEG) material layer 26 connected to the inner surface at a position corresponding to the position of the heating element. The NEG material layer may comprise a dense NEG material layer 28 and a columnar NEG material layer 30, which layers may cover the complete inner surface of the component. Thermal insulation may be included to provide a thermal barrier to prevent heat from the heating element spreading to other components of the vacuum apparatus.

Liquid blade pump

Номер: GB0002597952A
Автор: PAUL DAVID SMITH [GB], PETER ANTHONY MCBRIEN [GB]
Принадлежит:

A pump, for pumping a gas, having a rotor 10 and a stator 20 one of which has at least one liquid opening 12 from which is driven a stream of liquid that forms a liquid blade, or fluid vane, between the rotor and the stator such that, gas is confined and driven along a pumping channel (38, fig.5) by the relative rotation of the rotor and stator from an inlet 52 towards an outlet 54 and a cross-sectional area of the pumping channel increases from the gas inlet to the gas outlet. The radial width and/or axial width of the pumping channel, which may be helical (fig.2) or spiral, can increase towards the outlet as too can the size of the liquid opening and hence the volume of the liquid blade. The liquid opening may be a slit which is arranged as a helix around the rotor, or it may be formed of multiple smaller openings in a line. The pump can have a seal (32, fig.5) and be used as a vacuum pump that compresses the gas by having a decreasing cross-section of available space in the pumping channel ...

Fire suppressant apparatus

Номер: GB0002536630A
Автор: PAUL DAVID SMITH [GB], ROBERT GEORGE DUNSTER [GB], PAUL DAVID SMITH, ROBERT GEORGE DUNSTER, Paul David Smith, Robert George Dunster
Принадлежит:

A fire extinguishing apparatus comprises a container 100 for holding a fire suppressant, a valve 200 sealing said container and comprising a diaphragm 130 configured to perforate so as to release fire suppressant from said container. The apparatus further includes a pyrotechnic charge 140 for perforating said diaphragm and a barrier 150 configured to prevent contact of the fire suppressant with said diaphragm in use. The fire suppressant is preferably a powder suppressant. The barrier may be a gas-permeable foam extending across an outlet of the container and may be spaced from the diaphragm such that an air gap 230 is present there between. The barrier may be configured to deform upon perforation of the diaphragm to allow suppressant to be released from the container. Preferably the container is pressurised and the diaphragm comprises a metal disc having lines of weakness to aid perforation. A method of preparing the fire extinguisher and a valve for a fire extinguisher are also disclosed ...

Принадлежит:

A fire extinguishing apparatus comprises a container 100 for holding a fire suppressant, a valve 200 sealing said container and comprising a diaphragm 130 configured to perforate so as to release fire suppressant from said container, wherein the fire suppressant exerts a force on said diaphragm during use. The apparatus further includes a pyrotechnic charge 140 for perforating said diaphragm and a device 150, or cap, configured to reduce the force exerted by said fire suppressant on said diaphragm in use. The fire suppressant is preferably a powder suppressant and the cap is configured to support a portion of the suppressant material, thus reducing the weight of the suppressant acting on the diaphragm. The cap may be provided with apertures 152 to allow suppressant to flow through upon perforation of the diaphragm. Preferably the container is pressurised and the diaphragm comprises a metal disc having lines of weakness to aid perforation.

Vibration damping connector systems

Номер: GB0002552324A
Автор: PAUL DAVID SMITH [GB], PAUL DAVID SMITH, Paul David Smith
Принадлежит:

A vibration damping connector 10 system to connect between a vacuum chamber and a vacuum pump such that the vacuum pump is supported by the vibration damping connector system includes a first cylindrical member 12 and a second cylindrical member 16 that provide a flow passage 14, 18 through which gas can flow from the vacuum chamber to the vacuum pump. At least one sealing member 22, 24 is disposed intermediate the first and second cylindrical members to provide a gas seal and a securing system 26 securely connect the first and second cylindrical members. At least one resilient member 28, 30 disposed intermediate the securing system and a cylindrical member 12, 16 so that when the at least one sealing member 22, 24 is compressed by a pressure reduction caused in use by operation of the vacuum pump, the at least one resilient member can expand to enable the securing system to maintain a secure connection. Also claimed are vibration damping connector systems characterised by an isolator mass ...

A fire extinguishing apparatus comprises a container 100 for holding a fire suppressant, a valve 200 sealing said container and comprising a diaphragm 130 configured to perforate so as to release fire suppressant from said container. The apparatus further includes a pyrotechnic charge 140 arranged to combust to produce combustion products that form a shockwave directed onto the surface of said diaphragm. A device 150 encasing the pyrotechnic charge is also provided. The device comprises a hollow, elongate channel 155 located over the pyrotechnic charge and is directed at the centre of the diaphragm to focus or direct the combustion products onto the centre of the diaphragm. The elongate channel has a length that is at least 1.5 times its smallest width.
