Title: Poussoir miniature
Inventor: GAGNEBIN GASTON
IPC: G04G21/00
Filed: 1980-12-08
Abstract: Poussoir miniature pour pièce d'horlogerie comprenant une tige de commande (1) coopérant avec une douille (2) chassée dans la carrure (15). Pris pour lui-même, il constitue un correcteur dormant puisqu'il est dépourvu de ressort de rappel, ce qui permet de réduire fortement ses dimensions. La tige de commande (1) est construite de façon telle qu'on peut la monter depuis l'extérieur de la montre, ce qui rend très aisées les opérations d'assemblage et de désassemblage. Enfin, le poussoir est muni d'un système de retenue qui empêche que la tige (1) ne s'échappe de la douille (2) dans laquelle elle est montée. Le poussoir trouve son application surtout dans les pièces d'horlogerie de très faible épaisseur.

Abstract: In a high pressure hydraulic system a source (1) supplies pressurised fluid to a slave unit (7) through a control valve (3) operative to maintain the slave unit (7) in a desired condition. 
     Leakage from the slave unit (7) past the control valve (3) when the source (1) is inoperative is undesirable, but it is difficult to provide durable leakproof seals and to minimise valve operating forces at high fluid pressures. The control valve (3) therefore comprises two solenoid-operated valves (11, 12), oppositely acting and arranged in series between the source (1) and the slave unit (7), each valve (11, 12) being closed to prevent flow through the valve in a direction from the other valve and opened to permit flow in both directions, under the control of a solenoid (32, 38) and the pressure differential acting across the valve (11, 12), a seating portion (29) on a first valve (11) is of elastomeric material to provide a leakproof seal when that valve (11) is closed. 
     In the construction shown the slave unit (7) is an hydraulic suspension strut, and the system is adapted as a vehicular suspension levelling system, with the valves (11, 12) and the source (1) being manipulated as required by an electronic control system.

Abstract: A tandem quadrupole mass spectrometer system having first 10, second 14 and third 12 quadrupole sections close coupled in series with one another. AC voltages are applied to the centre section and conventional AC and DC voltages are applied to the two end sections. The AC applied to all three sections is synchronized in frequency. The AC phase shift between each section is of magnitude between 0 and 0.1 cycles in absolute value, preferably between 0 and 0.03 cycles in absolute value, and in the preferred embodiment the AC phase shift between each section is essentially zero. The sections are spaced apart longitudinally by a very short distance not exceeding r., the radius of the inscribed circle within the quadrupole rods. In this way ion losses between the sections are minimized, resulting in increased sensitivity.

Abstract: System for waste heat recovery, comprising a combustion machine (2,3) with a compressor (4) for the combustion air (30) and means (7) like a heat exchanger (13) and/or a recirculation duct (14), to transfer heat, contained in the combustion gases (37,38,39) after their expansion in the machine (3), to the combustion air flow (33) before its entry into the compressor (4). Water (8,8') is introduced into the (to be) heated combustion air flow (30,33) cooling it by its evaporation, and the vapor is partially condensed again in a cooler (6) fitted in the compressed flow (34) after leaving the compressor (4). The condensation can take place at higher temperature, thus the system acts as heat pump for the waste heat. The compressed air flow (35) enters extra cooled into the combustion chamber (2) which provides an additional advantage. For the compressor (4), combustion chamber (2) and turbine (3) a normal gas turbine may be used.

Abstract: In an axial flow rotary compressor a fluid flow inlet (12) is circumferentially separated from a fluid flow outlet (20) by a dynamic flow splitter (18) comprising at least one toroidal chamber (27) providing a loop fluid flow path (24) intersecting the path (23) of the rotor blades 2 such that any fluid leakage through the flow splitter flows around the loop flow path (24). Regeneration of the flow through the rotor blades (2) as they emerge from the flow splitter (18) is thus facilitated. The flow splitter (18) may comprise a number of contiguous chambers (27-31) whose apartures can increase towards the low pressure end of the flow splitter to compensate for the decreased density of the fluid. The downstream walls (22) of the flow splitter chambers can be offset relative to the upstream walls (21) so as to provide a direct quasihelical fluid flow path through the flow splitter to increase the enthalpy transport through the flow splitter.

Abstract: An improved insulating composition has been discovered which has general use in the construction field for providing a thermal and / or acoustical barrier. This novel composition is formulated from a particulate insulating material (e.g., fibers or porous solids) and a foamed binder component based upon an organic or water-soluble silicate adhesive material. The composition requires a relatively minor amount of adhesive and is easily handled and applied where the resulting barrier has a low density and excellent insulating properties.
