Title: Electrostatic precipitator for sepg. particles from gas - with precharging, charging and collecting stages reducing re-entrainment
IPC: B03C3/12
Filed: 1973-04-13
Abstract: An electrostatic precipitator, for sepg. particles from a gas, consists of a duct in which there are three sections, for precharging, charging and collecting stages respectively. The precharging stage incorporates several electrodes close together forming openings through which the particles and the gas flow. The charging stage has emissive electrodes which establish an emissive electric field downstream of the precharging stage to charge the particles to satn. The collecting stage has a central non-emissive electrode which establishes a collector field over a considerable length of the duct, and a no. of emissive electrodes, opposite the central electrode, which create an ion spray, promoting turbulence in the aerodynamic boundary layer. The precipitator is simple and efficient and can be used for all applications, e.g. for any particle load, for high flow rates and continuous operation, whereas the Cottrell precipitator is used generally for high concentrations, low flow rates and continuous operation and the two stage type is used only for low concentrations, high speeds and intermittent operation.

Title: Contact switching circuit - has an oscillator with a sensor which, when touched by the operator, changes the oscillation amplitude
IPC: H03K17/945
Filed: 1974-11-25
Abstract: An amplitude-voltage converter is connected to the oscillator and delivers an output signal which reproduces the oscillator amplitude.

Patent FR-2313276-A1 (FR)
IPC: B65D30/00
Filed: 1975-06-06
Abstract: A packet is used to protect valuable documents. A sliding clasp fastener (8, 9) with two sliders (14, 15) is used to close the access to the packet. The sliders are moved to the centre of the front face of the packet, so that after the top part of the packet is folded over it is impossible to touch the sliders. Folding over the top part brings two rows of eyelets (21, 23) into alignment. Strips of material (27, 28) which stick together face to face by pressure alone hold the eyelets in the correct relative position while a second fold is made. This lines up a third row of eyelets (25) with the others. The three sets of eyelets can then be laced up with metal wire. A piece of plastics strip can be inserted as a stiffener adjacent to the fastener.
