Abstract: Ces ensembles à soupapes centrales sont des composants d'importance vitale pour la sécurité et doivent répondre à des exigences sévères (montage irréprochable, fiabilité). La soupape centrale comprend une tige (25) sur laquelle sont agencées deux coupelles de ressort (29, 31) pourvues de ressorts de rappel (15) précontraints. Les coupelles de ressorts (29, 31) sont saisies par derrière grâce à des agrandissements de section de la tige de soupape (25), laquelle comporte un élément de fermeture de soupape (33). Un agrandissement de section est formé par un épaulement (26) de la tige de soupape (25). Un autre agrandissement de section est constitué par un manchon (36) qui est guidé longitudinalement sur la tige de soupape (25). Le manchon (36) comporte sur sa face opposée aux ressorts un alésage interne élargi (38) avec lequel il s'emboîte sur un circlip (35) s'engageant dans la tige de soupape (25). On obtient ainsi une liaison de forme entre le manchon (36) et la tige de soupape (25), qui assure la cohésion du bloc pré-assemblé constitué des parties précitées.

Abstract: Disclosed is a magneto-optical recording apparatus for recording an information signal on or for erasing an information signal from magneto-optical recording media by irradiating the magneto-optical recording media with a beam of light while applying a magnetic field thereto. The magneto-optical recording apparatus includes, as a magnetic field application device, a composite magnetic head which includes a first magnetic head capable of modulating a generated magnetic field in accordance with an information signal, and a second magnetic head capable of generating a constant magnetic field which is not associated with the information signal and capable of switching the direction of the constant magnetic field. This provides a magneto-optical recording apparatus which can use magneto-optical recording media for both light modulation type recording and magnetic field modulation type recording, and which ensures overwriting without increasing the overall size of the apparatus.

Inventor: SEDDON RICHARD I
IPC: G02B5/28
Filed: 1991-07-04
Abstract: The disclosure relates to a leak-corrected linearly variable filter (90) comprising optical filter coatings formed on an assembly of one or more optically transmissive substrates (91, 92, 93). Leaks due to the longitudinal precession of incident light within the substrates are suppressed by forming the filter such that no two surfaces which are reflected at the same wavelength within the range of interest are parallel. Typically, the constituent substrates (91, 92, 93) of the filter are oriented at a slight angle relative to one another, the angle being perpendicular to the direction of increasing wave length along the substrate. The filter coatings having overlapping reflective wavelengths are deposited on different substrates rather than on the two parallel sides of the same substrate. Alternatively, venetian shade structures can be incorporated within the substrates to block longitudinal precession of light.

Abstract: An apparatus and method for patient elevation above a fluidized surface includes a web (72) of filter sheet material disposed beneath the patient and between the patient and the main filter sheet (26) that covers the fluidized surface. The web (72) is loosely mounted about a pair of support rods (66,68) which are connected via a pair of splice bar linkages (48) to a pair of dual acting hydraulic cylinders (76,78). Activation of the cylinders (76,78) causes the two rods (66,68) to separate from one another. The separation takes up the slack in the web (72) and renders it taut about the two support rods (66,68). Further activation of the cylinders (76,78) elevates the two support rods (66,68) above the fluidized surface by pivoting them through the splice bar linkages (48). This raises the web (72) and the patient supported on the web (72).
