Abstract: A pressure relief valve comprises a housing (10) having a stepped bore comprising a first portion (18) and a second portion (18) extending through the housing (10). An annular shoulder is formed in the housing to define a valve seat (19). A piston (22) is slidable in the housing (10) and a spring (30) biases the piston (22) into engagement with the seat (19). The spring (30) is retained by a cap (32). A seal between the piston (22) and the seat (19) is made by an 0-ring (25) located in an annular groove (23). Passageways (37) adjacent the seat (19) communicate the exterior and interior of the housing (10). The total cross-sectional area of the passageways (37) is less than the area of the second bore portion (20) causing, in operation, a pressure build-up in the first portion (18) below the piston (22) which increases piston movement. 
     The pressure relief valve is particularly suitable for use on life rafts.

Abstract: Procede pour faire fonctionner une installation de pompe chauffante-refroidissante. Le degivrage des evaporateurs au moyen de liquide chaud a haute pression provenant du compresseur a precedemment ete effectue en faisant fonctionner l'installation a l'envers, c'est a dire en utilisant alternativement les condensateurs en tant qu'evaporateurs et les evaporateurs en tant que condensateurs et vice-versa, ou en doublant les evaporateurs, dont l'un reste actif pendant que l'autre est degivre. Il existe des inconvenients dans ces deux systemes et le but de l'invention est d'eliminer ces inconvenients et de fournir une installation de construction et de fonctionnement simples et qui fourni un facteur moyen eleve par an pour l'effet d'emission de chaleur. Ceci a ete obtenu par le fait que les evaporateurs (21, 22) qui doivent fonctionner en tant qu'emetteurs de chaleur pendant le degivrage sont essentiellement completement vides du refrigerant, lequel apres compression et condensation, est entrepose dans un reservoir (15). Le degivrage du ou des evaporateurs vides (21, 22) est effectue au moyen du condensat de refrigerant sous haute pression en provenance du reservoir (15) et du condenseur super-refroidi est rajoute aux evaporateurs, qui sont en etat d'absorption de chaleur, en provenance des evaporateurs en etat de degivrage a partir d'un recipient d'operation (17). Du condensat de refrigerant est aussi conduit par la voie du recipient d'operation (17) a l'un ou a ceux des evaporateurs (21, 22) destines a servir en tant qu'absorbeurs de chaleur et/ou emetteurs de chaleur.

Abstract: Capteur de rayonnement solaire du type plan et fixe. Il utilise un panneau absorbeur de chaleur dont la surface active est formee par une plaque mince (2) thermiquement conductrice profondement ondulee suivant des ondulations a section trapezoidale et recouverte de noir de fumee. Une seconde plaque (3) de preference plane est soudee a la premiere et forme de petits canaux que le fluide caloporteur parcourt verticalement.

Abstract: A dielectric waveguide comprises a wave propagating member having a core with a refractive index n 1  and a cladding with a refractive index n 2 , the core having an elongate cross-section with a magor axis a and a minor axis b. The values of n 1 , n 2 , a and b are such that only the two orthogonally polarized fundamental modes of a wave with a prescribed wavelength can propagate through the core, thereby avoiding propagation of unwanted higher order modes of the wave, and such that the group velocities of the two orthogonally polarized fundamental modes are substantially equal so that any accidental coupling between the fundamental modes does not reduce the bandwidth of the waveguide.

Abstract: In one embodiment a slip coupling is incorporated as part of a bracket (12) for supporting one end of the roller (1). The bracket (12) has a cylindrical bearing (15) which is rotatable within a circular aperture (16) in the face of the bracket (12) and receives a pin (5) of a spindle (4) of the roller so as to be rotatable therewith. The bearing (15) carries a spring (20) the ends of which engage with stops (30) on the face of the bracket (12) so that the bearing (15) is prevented from rotation when the torque exerted by the motor spring (7) is below a predetermined level. When the motor spring (7) is overwound the ends of the springs (20) are caused to flex to override the stops (30) and so reduce the tension in the motor spring (7). In a second embodiment the slip coupling is located within the roller (1).

Abstract: The electron applicator incorporates a stationary support tube (2) and an insert tube (12). The support tube and the insert tube each have a first end portion and a second end portion. The first end portion of the insert tube slideably extends into the second end portion of the support tube. Electrons of high energy are transmitted through the assembly of both tubes. The surface of the insert tube is tapered inwardly toward the end thereof in the travelling direction of the high energy electrons. A device is provided for preventing the insert tube from sliding out of the support tube. A first engaging device engages the insert tube in a first working position. This device is such that upon a predetermined axial force which may inadvertently be exercised by a patient under treatment, the insert tube will slide into the support tube. 
     An adapter for small field or cavetory treatment may be connected to the output end of the insert tube. To compensate for the additional length of the tube assembly associated with such an adapter, the insert tube is moved into the support tube by a distance (L) equal to the effective length increase and held in this second position by a second engaging device which can be similar to the first engaging device.
