Abstract: An anode assembly, suitable for use in solder plating, comprises a plurality of relatively short anode sections (2) mounted on a retaining rod (3) the upper end of which screws into a hook (6) by means of which the anode assembly is hung from a busbar when in use. The anode sections (2) are preferably of the same length, generally 0.20 metres, and can be made from a tin/lead alloy or from pure tin. This anode assembly avoids the conventional necessity of stocking anodes of various lengths and of having to discard a whole anode when only the lower end becomes too thin, and has the advantage that the central bore (10) present in each anode section can be of differing cross-section as an aid to identifying the material from which a particular anode section has been manufactured.

Abstract: A wheelchair for handicapped or elederly persons consists of a seat supported by a generally rigid chassis or frame (242,243,244,248), the chassis or frame being supported on a pair of rear wheels (90) and front castor wheels (26). Each wheel is movable relative to the frame between an extended operative position and a retracted inoperative position. Each rear wheel (90) is rotatable about an axle (92) carried at the end of a respective swing arm (140) which rotates about a fixed stub axle (93) extending outwardly from a respective side (94, 95) of the sheet metal box structure (244). Each stub axle (93) is skewed rearwardly so that rotation of the swing arm (140) about the skew axis from a position in which the wheel axle 92 is horizontal not only skews the respective wheel (90) to the vertical to reduce the track width of the chair but also produces a rearward convergence or toeing-out, of the wheels. The chair is thus able to fit between the transmission tunnel and the door sill of a small, family sized motor vehicle, and the occupant of the chair is less hemmed-in by the tops of the wheels when these are in their raised, retracted positions.

Abstract: A heat pipe heat exchanger in which groups of heat pipes are arranged within a box, the center of which is partitioned, a high temperature fluid flows on one side, a low temperature fluid flows on the other side, thereby transferring the heat of the high temperature fluid to the low temperature fluid via fluid sealed in heat pipes. In the heat exchanger, a plurality of heat pipes which are bare tubes at least on the high temperature fluid passage side are arranged across both passages, and the heat pipes on the high temperature fluid side are inserted into pipes without fins. At least the outer surfaces of the pipes without fins are treated for corrosion resistance. Since the pipes without fins and the heat pipes are joined by a thermally conductive substance, the heat pipes can be easily removed, and accordingly the efficiency of the heat exchanger can be increased or decreased as required.

Abstract: Un circuit de commutation de transistor permet d'effectuer la commutation d'un transistor de puissance (28) d'un état sous tension vers un état hors tension à des vitesses élevées avec une dissipation minimum de puissance et sans rencontrer de charges disruptives secondaires dans le transistor de puissance. Le circuit de commutation du transistor comprend un transformateur (36) ayant un enroulement secondaire (35) connecté à la base (30) du transistor de puissance (28) et un enroulement primaire (49) connecté à une logique de commutation (38), le transformateur (36) assurant une isolation galvanique entre le transistor de puissance (28) et la logique de commutation (38). La logique de commutation (38) comprend un premier commutateur (50) et un second commutateur (52). Lorsque le premier commutateur (50) est sous tension et le second commutateur (52) est hors tension, l'enroulement secondaire (35) du transformateur (36) développe un courant de base positif appliqué au transistor de puissance (28), mettant ainsi le transistor sous tension. Pour unifier la commutation du transistor (28) sur son état hors circuit, le premier et le second commutateurs (50, 52) sont tous les deux en circuit, ce qui fait cesser la conduction de courant par l'enroulement secondaire (35) pour permettre aux porte-charges collecteurs du transistor (28) de se recombiner. Après que les porte-charges collecteurs sont recombinés de manière suffisante, cette recombinaison étant détectée par un circuit de détection de saturation (62), le premier commutateur (50) est mis hors circuit, le second commutateur (52) restant sur "on" de sorte que l'enroulement secondaire (35) développe un courant négatif appliqué sur la base du transistor de puissance (28), mettant le transistor (28) rapidement sur "off". Le circuit de commutation du transistor comprend en outre des moyens pour limiter la tension d'émission de base du transistor et des moyens pour remettre à zéro rapidement le noyau du transformateur.

Abstract: Un amortisseur (10) possède un assemblage de butées de rebond de suspension (22). L'assemblage de butées de rebond de suspension (22) repose sur un épaulement (30) fixé à une bielle de piston (16). L'assemblage de butées de rebond de suspension (22) comprend une bague élastomère (24) interposée entre deux colliers (26 et 28) formant ue chambre annulaire (74) entre les deux colliers. A l'extrémité de la course de rebond de la bielle de piston (16), l'assemblage de butées de rebond de suspension (22) est comprimé axialement entre l'épaulement (30) de la bielle de piston (16) et le guide bielle (18) jusqu'à ce que la bague élastomère (24) se déforme pour s'appuyer contre la paroi intérieure (64) du cylindre de travail. Au fur et à mesure que la bague élastomère se déforme, la chambre annulaire diminue de volume. Un passage restrictif (71) permet un écoulement restreint de fluide. Une chambre supplémentaire (70) est formée et est en communication restreinte par un fluide passant au travers du passage (71) avec la section (68) de la chambre de rebond (20). Une compression supplémentaire de butées de rebond de suspension (22) réduit le volume des deux chambres (70 et 74) et provoque un écoulement de fluide limité sortant de ces chambres au travers du passage (71) et entrant dans la section (68) de la chambre de rebond (20). La compression de la bague élastomère et l'écoulement de fluide restrictif assurent un amortissement supplémentaire à la fin de la course de rebond.

Abstract: The toothpick of the invention is shaped to reproduce faithfully the shape of the interstices between the teeth at the base of the teeth. For this purpose, it exhibits substantially trapezoidal sections decreasing toward the tip, with tapering curved sides. The upper front part (B, E, F) is concave and the lower front part (G, H, B) is curved upward. 
     The base of the tip (HB) is impregnated with antiplaque, antibacterial and scented substances, while the sides (1') are coated with a toothpaste with a base of fluorine and a slight abrasive. 
     The entire unit is protected by a film that is removed mechanically and by the action of saliva when the toothpick is inserted in the interstices between the teeth. 
     The toothpick not only makes possible the removal of residue bodies from mastication, inserted in the interstices between the teeth, but especially removal of bacterial plaque and tartar with the deposition of antiplaque substances, as also brushing of the teeth and administration of fluorine, thus impeding caries.

Abstract: Un circuit permettant de changer la fréquence d'un train d'impulsions (10) en réponse à un changement de la valeur moyenne d'un signal numérique appliqué (18) applique le signal à changer à un soustracteur d'impulsions (12). L'application d'un nombre prédéterminé de signaux de données numériques d'un signe donné entraîne la soustraction périodique d'une impulsion dans le soustracteur (12), réduisant ainsi la fréquence moyenne à la sortie du soustracteur d'impulsions (12). Le signal à la sortie provenant du soustracteur est appliqué à un additionneur d'impulsions (14) qui additionne une impulsion au train d'impulsions soustraites en réponse à un nombre prédéterminé d'impulsions de données du signe opposé. La fréquence du train d'impulsions de sortie (16) varie ainsi en réponse à la variation de la valeur moyenne de l'entrée de données numériques. L'ordre d'addition et de soustraction peut être inversé.
