Patent EP-0021709-A1 (EP)
Inventor: WIGGINS JESSE O
IPC: F04D29/28
Filed: 1980-06-10
Abstract: A centrifugal air compressor (11) has an annular air flow path (14) of progressively increasing diameter and progressively diminishing cross-setional area in which a plurality of internal compression-diffusion stages (30a to 30f) are provided. The stages of progressively greater diameter are defined by sets (29a to 29h) of impeller blades (12) which alternate with sets (32a to 32h) of stator blades (13) along the air flow path (14) and each such stage (30a to 30f) has a diffusion factor below about 0.55. The multi-stage construction combines higher isentropic efficiency with reduced size and may be used as a component of a gas turbine engine (18) or a turbocharger (57) or for other purposes requiring gas compression.

Abstract: Le dispositif absorbeur d'energie cinetique qui fait l'objet de l'invention concerne principalement l'absorption des chocs de haute energie qui resultent de la rencontre d'obstacles par tous types de mobiles ou de vehicules. Ce dispositif est constitue d'un penetrateur male indeformable (29) et d'une piece receptrice femelle (27) en metal ductile. L'un de ces deux organes est solidaire du mobile tandis que l'autre est soumis a l'action de l'obstacle qui s'oppose au deplacement du mobile. Sous l'action du choc, le penetrateur s'introduit dans la piece femelle qu'il deforme plastiquement. C'est ce travail de deformation plastique qui absorbe la majeure partie de l'energie cinetique. La piece femelle est realisee de preference en acier austenitique a austenite instable. Ce dispositif permet en particulier l'absorption des chocs violents subis par les vehicules automobiles.

Abstract: Apparatus for dispensing a mixture of mutually reactive liquids, such as a hardenable plastic foam, comprises a metal housing with a plastic mixing chamber (13) disposed in the housing and having a bore (29) therethrough in which a purging rod (19) reciprocates to clean reactive mixture from the bore. The reactive liquids are separately introduced into the bore through the mixing chamber via valve assemblies (9, 11) whose metal housings extend through the plastic mixing chamber and terminate at the bore. The purging rod retracts rearwardly into a scraper (61) that is immediately behind the inlet openings for the liquids, the scraper being disposed in a recess in the rear of the plastic mixing chamber. The plastic mixing chamber is compressed rearwardly, so that it seals against the valve housings and the scraper. Also, the valve housings have a crush fit with the plastic of the mixing chamber, to augment the seat. Air nucleation can be provided, by feeding the air radially inwardly through the wall of the bore between the liquid inlet openings (85) and the scraper (61).

Title: Fire simulation device for small arms or the like
Inventor: ALLARD JEAN-CLAUDE
IPC: F41G3/26
Filed: 1983-07-25
Abstract: The simulation device provides training in the firing of rockets or guided missiles by means of a shoulder weapon. As soon as a shot is fired, the firer's field of view is occulted by a shutter. The aim at the instant of firing and the point of impact with respect to the target are displayed on an instructor's video screen. The target can be of a fictitious type generated by a computer and produced within the field of view of both the instructor and the firer at the same time. In the case of a real target, an index can be controlled by the instructor in order to locate the target and follow its progress up to the instant of firing. The result of the firing operation is judged according to the position of the point of impact with respect to the fictitious target or with respect to the index. The choice of the mode of operation is made on a control desk.
