Title: Microchannel electron multiplier - uses varying wall resistivity for low signal to noise ratio or low emission dispersion
Inventor: DUCHENOIS VALERE
IPC: H01J43/24
Filed: 1974-05-10
Abstract: This electron multiplier uses either a single microchannel or a multiple assembly. The internal walls of the channel have the property of secondary emission and their resistivity varies by a factor of 1.5 to 10 relative to the average linear resistivity along the channel. When the value is low at the input (e) then the input field will be weaker and the parasitic electron emission will also be low giving a low signal to noise ratio. When this condition is reversed at the output (s) then a low electron dispersion is obtained.

Title: Coarse screening grid unit with moving rake - for removal of detritus from waste water and sewage
IPC: B01D29/03
Filed: 1974-10-03
Abstract: Coarse screening grid unit, with moving rake, is intended to separate the large solid detritus from waste water and sewage. It comprises a series of parallel rods with a base portion, inclined towards the rear, or a portion inclined to the front. At the upper end a rear extension is inclined downwards at an angle of 30 degrees with the vertical. A receptacle is arranged below this rear portion. An endless belt carrying a series of teeth is arranged upstream of the liq. flow. When debris carried by the liq. current is caught between the rods of the grid it is removed by the ascending teeth and taken to the descending portion from which it falls into the receptacle for evacuation. The incurved form of the base of the grid, either to the front or to the rear, allows of perfect raking of the lower portion. As the moving rake is upstream of the grid there is no risk of blockage with detached impurities.
