Patent FR-2329861-A1 (FR)
Title: Carburettor with auxiliary throttle flap - has sprung diaphragm pneumatic regulator operating series of taper needles to regulate fuel flow for each cylinder
Inventor: MENNESSON ANDRE
IPC: F02M7/12
Filed: 1975-10-31
Abstract: The carburettor air intake has an auxiliary throttle flap upstream of the main throttle. The auxiliary throttle opens automatically and progressively corresp. to air intake vol. and its pivot shaft is mechanically linked to a fuel metering unit in the float chamber which has a number of taper needles. Each needle is able to vary the cross section of a feed pipe leading to a pneumatic regulator on each cylinder intake port. Each pneumatic regulator has a sprung diaphgram dividing a housing into two parts. The diaphragm movement is transferred to a needle valve to regulate the fuel pressure outlet. Each diaphragm chamber is connected to a depression source between the auxiliary air flap and the main throttle valve.

Title: Nozzle providing irrigation by droplets - has diaphragm and helical channel with grooves to ensure flow is independent of pressure in pipe
IPC: A01G25/02
Filed: 1975-12-10
Abstract: The nozzle provides irrigation by droplets, the rate of feed being independent of the water pressure in the supply pipe. The water enters from this pipe (2) into a chamber in the body of the nozzle. In the chamber is a thick dished diaphragm (108) provided with a hole (112) through its centre. The water pressure flexes this diaphragm, altering the hole diameter and regulating the flow through it. The water passes through an orifice (111) in a retainer cap (110) sealing the diaphragm slong a helical channel (102) and through labyrinth grooves (105) where it is discharged (106) as droplets out of an inner body (101).

Title: Wall mounted electric central heating boiler - has by=pass between flow and return with adjustable valve
IPC: F24H1/08
Filed: 1976-08-06
Abstract: The boiler has electric heater elements running through horizontal water tubes between a return header and a flow header and a pump is connected directly to the outflow of the flow header. A console on the boiler contains controls including a thermostatic regulation of the electric input. A bypass is provided between the flow and return connections within the boiler casing. An adjustable valve regulates the flow through the bypass and is constructed so that there is a minimum bypass flow when the valve is completely shut. This enables the boiler to be adjusted to the hydraulic characteristics of the circuit it serves and ensures a minimum flow over the electric heating elements.

Title: Refractory structure for furnace components - partic. for air-cooled burner support beams and injection heads in limestone furnaces
Inventor: VERNEY SIMON SERGE
IPC: F27B1/10
Filed: 1976-10-20
Abstract: A refractory structure, for building internal components of vertical furnaces, incorporates a core of sheet metal, with longitudinal and transverse partitions fixed on it, perpendicular to its surface. The partitions form four-sided cells closed on one side by the core and open on the other side. The cells are filled with refractory material.
