Abstract: An improved muffler including a body 2 with an exhaust inlet 3 in the form of a porous pipe enclosed in s second porous pipe 31 for diffusing exhaust gases into the interior of body 2. A pair of pipes 5 introduce ambient air into the discharge region of the muffler. A constricted discharge opening 41 of the body 2 encircles the pipes 5 and confine helical vanes 51 which impart a helical path to the exhaust gases just before mixing with ambient air from the pipes 5. A venturi section 6 with a bell shaped outlet 62 completes the tailpipe section 4. An auxiliary air inlet 43 to the venturi 6 adds additional ambient air to the final outlet via ports 63. In an additional embodiment(Fig. 8), the venturi section 113 is within the muffler body 100. A constricted tube 121 provides a direct path for a portion of the exhaust gases while the major quantity of exhaust gases traverse the helical paths defined by the vanes 123.

Abstract: Improvement in tubular telescopic struts for ensuring greater safety.   The improvement involves adding to the base of the shank a tubular abutment 15 force-fitted into the tube 8 and welded to the plate 3. The stroke of the slide 7 is limited in this way, to prevent the possibility that the hand will be crushed between the plate 11 and the nut 6, and the fingers between the slide 7 and the plate 3. The abutment also reinforces the base of the shank which better withstands sledgehammer blows. It is also possible to place at the head of the slide a reinforcement 16 which is also capable of receiving sledgehammer blows if the strut is arranged with the slide downwards. This improvement can apply to all conventional tubular telescopic struts used particularly on public works sites, civil engineering sites, building sites, etc. <IMAGE>

Abstract: In the described process, a restricted number of moulds (T1, T2, ...., TN) having standardised parameters (for producing the following contact lens parameters: contact lens diameter, radius of curvature of the contact lens rear surface, vertex power) are used to produce standardised casting moulds (M1, M2, ...., MN). By preferably material-removing machining of the casting moulds, casting moulds having additional, altered parameters are prepared. The wide variety of casting moulds prepared in this way is used for the single-stage production (F) of contact lenses (L) of different parameters requiring virtually no finishing.

Abstract: Dans un mode de réalisation du procédé et de l'appareil, on utilise une pluralité de chambres gonflables de fluide (120, 130) et des moyens associés (140, 150) pour régler la pression de fluide dans chaque chambre (120, 180). Au moins deux de ces chambres sont physiquement agencées de sorte que le gonflement d'une des chambres et le dégonflement de l'autre chambre complémentaire amènent un personnage (110) ou une partie d'un personnage à prendre une position spatiale différente qui dépend du niveau de gonflement de chaque chambre. Dans un autre mode de réalisation, on utilise une seule chambre gonflable dont une paroi a une section moins élastique que la partie restante de la paroi. Compte-tenu de la différence d'élasticité, lorsque la chambre est gonflée elle prend une forme ou un agencement différent de celui de la chambre non gonflée. Dans un troisième mode de réalisation, deux chambres (540, 550) gonflables de fluide sont enroulées en spirale dans des directions opposées, sensiblement parallèles. Lorsqu'une pression de fluide est appliquée à l'une ou à l'autre chambre (540, 550), ladite chambre se met en rotation, déroulant des spires hélicoïdales tout en serrant dans une même mesure les spires de l'autre chambre.

Abstract: Un mécanisme de vannes amélioré dans le coulage d'alliages métalliques a basses températures de fusion comprend deux vannes (22, 46) dans un seul ensemble situé à l'intérieur d'un réservoir d'alliage (10). Les vannes situées dans le réservoir réduisent la formation d'oxydes pouvant se produire dans l'air, et elles tendent à réduire les fuites. L'appareil comprend un réservoir (10) adapté pour contenir des alliages métalliques en fusion, un cylindre (16) situé à l'intérieur du réservoir (10) présentant au niveau de sa base une connexion à un passage d'injection (20), lequel conduit par l'intermédiaire du réservoir (10) à une matrice (58) située à l'extérieur du réservoir (10). Un piston (18) va et vient à l'intérieur du cylindre (16). Deux vannes (22, 46) sont ménagées dans le passage (20) se trouvant dans le réservoir (10), lequel permet à l'alliage métallique en fusion de passer dans le cylindre (16), et de s'écouler à travers le passage (52) jusque dans la matrice (58). Un système de commande (86) destiné au piston (18) régule avec précision la vitesse du piston (18) dans le cylindre (16) lorsque l'alliage métallique en fusion est acheminé à la matrice (58).

Abstract: 2.1. It is necessary to be able to operate heating boilers with exhaust (waste, flue, exit) gas values which are especially environmentally friendly (inter alia with an especially low NOx fraction) and in an especially economic manner; they must be designed to be as compact as possible. Heating boilers of conventional design realise only a part of these aims alternatively. The novel design is intended to achieve these aims simultaneously and, additionally in an optimum fashion, by means of a simple third waste gas flue. 2.2. For this purpose, the third flue (10) of a three-flue heating boiler using finned technology is positioned in a channel on the periphery of the combustion chamber (1). 2.3. This type of design is advantageous for heating boilers in which a compact configuration is particularly important. <IMAGE>

Abstract: A tubular bushing (68) is positioned into an opening (92) in a member (88). An axially split expansion sleeve (66) is placed onto a small diameter portion (54) of an extended mandrel (40). The mandrel (10) includes an increasing diameter portion (56) and a maximum diameter end portion (58) endwise from the small diameter portion (54). The maximum diameter portion (58) is sized to fit through the tubular bushing (68). The expansion sleeve (66), while on the small diameter portion (54) of the mandrel (10) can also fit through the bushing (68). The sleeve (66) is placed on the small diameter portion (54) of the mandrel (10) with its inner end (76) against the end (78) of a sleeve positioner (40). A tubular nosepiece (16) surrounds the sleeve positioner (40), and extend axially beyond the end surface (78). The mandrel (10) is inserted through the bushing (68) while the bushing (68) is within opening (92). The mandrel (10) is moved to place the sleeve (66) within the bushing (68), and an end surface (41) of the nosepiece (16) against a surface portion (84) of the workpiece (88). At the same time, the end surface (43) of a nosepiece extension (39) is positioned against an end surface (82) of the bushing (68). The mandrel (10) is then pulled through the sleeve (66). Movement of the increasing diameter portion (56) and the maximum diameter portion (58) through the sleeve (66) imposes a radially outwardly directed force on the sleeve (66), causing the sleeve (66) to expand. The expanding sleeve (66) exerts a radially outwardly directed force on the bushing (68). In response, the bushing (68) is expanded radially into a secure interference fit within the opening (92) in the workpiece (88).
