Title: Mfr. of inhabitation units - using retractable mandrel mould with jacks and sliding shutters
IPC: B28B7/22
Filed: 1974-05-29
Abstract: The fabrication system for the manufacture of prefabricated three-dimensional cells, (e.g. cells representing habitation units), uses a retractable mandrel mould forming the core or internal shutter, this mould being able to rotate w.r.t. a horizontal axis and thus presenting wall elements in successive upper horizontal stations, with the wall pours being effected whilst each element is in this station. The mould uses jacks arranged on a horizontal axle and a sliding arrangement of shutter panels and supports. The absence of external forms facilitates the placement of reinforcement cages etc; and the mould is used in conjunction with a semi-automatic overhead gantry concrete supply system.

Title: Variable demand fuel oil atomising burner - has concentric annular passages and axial connecting passages
IPC: F23D11/28
Filed: 1974-08-01
Abstract: The oil feed and return pipes run concentrically down the centre of the combustion air duct. The oil feed is controlled by a 3-way cock which bypasses the burner. Tangential passages connect the mixing chamber and air duct, axial passages leading from this chamber. A set of radial holes in the atomising head which can be blocked off under certain conditions enables the flame exit angle to be modified. Thus with the dual control the burner is suitable for variable load conditions giving quick response.

Title: Continuous purification of material by advancing fusing zone - is regulated using viscous torque as control parameter
Inventor: QUENISSET JEAN-MICHEL
IPC: C30B21/02
Filed: 1974-08-21
Abstract: A method of regulating a bath of molten material consists of measuring a mechanical force resulting from viscous friction generated in the bath. In partic. a viscosity moment produced by the relative rotation of the bath of molten material and of the solid part of the material undergoing treatment, is measured. More specif. the mechanical force resulting from viscous friction is converted into a form where it can be compared with a threshold value or set point, to give a control variable of the on/off type. Alternatively, an analogue control may be used. Esp. for flat zone purification of material, e.g. in bar form, where a heating zone is progressively advanced along the bar to melt and purify the material without any contact with a crucible. The method enables the size of the fusion zone to be accurately measured and consequently regulated as a function of the viscosity between the rotating solid and molten parts.

Title: Hot refractory lining thickness measurement - using gamma radiation source and reference values
Inventor: ARNOULT JEAN
IPC: G01B15/02
Filed: 1976-03-12
Abstract: The thickness of the refractory lining of a metallurgical vessel is measured by introducing at a specific point a source of gamma-radiation of known intensity. Measurements are taken at specific points, outside the vessel, the intensity of the radiation which has passed through the lining. The values obtd. are compared with reference values obtd. from the furnace with a new lining, the differences being in direct relation to the variation in the lining thickness.

Title: Air motor driven tool exhaust silencer - has expansion chamber around motor with discharge into further chamber formed in tool hood
IPC: B23Q11/00
Filed: 1977-01-11
Abstract: A pneumatic tool (1) has an air motor (2) within its casing to drive a shaft (4) which carries a grinding wheel (5) or other attachment on its end.
