    摘要: A drill bit (20) for a modular arm (70) is provided. The modular arm (70) includes an inside surface (76) having first (144) and second (146) angled surfaces whose lower portions form an inwardly projecting wedge (125). A curved throat relief area (87) connects to a lower edge (152) of the wedge (125). A pocket (54) in the drill bit (20) is sized to receive the support arm (70). The pocket (54) includes a wedge-shaped recess (121) sized to receive the wedge (125) of the support arm (70). A triangular weld groove (126) is provided in the convex surface of the bit body (40). A length of weld (128) is applied in the weld groove (126) for firmly securing the support arm (70) to the bit body (40).

    摘要: A rotary cone drill bit (10) for forming a borehole having a bit body (18) with an upper end portion (20) adapted for connection to a drill string (21). A number of support arms (24) extend from the bit body (18). Each support arm (24) has an exterior surface (38). A number of cutter cone assemblies (12) equal to the number of support arms (24) are mounted respectively on the support arms (24) and project generally downwardly and inwardly with respect to an associated support arm (24). A ramp (36) is formed on the exterior surface (38) of the support arm (24) and is inclined at an angle from the leading edge (40) of the support arm (24) toward a trailing edge (42) of the support arm (24) such that the ramp (36) directs cuttings upward in the borehole.

    摘要: Step exercise apparatus (10) primary intended for use in an aquatic environment such as a pool or the like. The apparatus includes a step platform (11) maintained in elevated relation above a foundation surface by a pair of support members (12). The apparatus has a specific gravity greater than one so as to sink within a body of water, and slots (23) extend through the platform to prevent entrapment of air bubbles when the platform is placed in a pool. Handles (36) in the sides and ends of the apparatus assist the user in manipulating the apparatus while exercising in the water. Removable extension feet (43) selectively increase the step distance between the platform and the pool bottom or other foundation surface on which the apparatus rests.

Lesdits coutres (1) sont, de préférence, également levés en position de repos avec les socs d'ornière (13) pour éviter de défaire à tort les ornières formées par les roues du tracteur.

    摘要: Un mécanisme doseur comprend un boîtier (7) comportant un orifice d'admission de matériau (12) et un organe doseur rotatif (27) monté entre les parois latérales (8, 9) du boîtier, la périphérie de l'organe étant en communication avec une chambre (48) dans le boîtier, de manière à doser le matériau provenant de la chambre, lors de la rotation de l'organe. Le mécanisme est caractérisé par ue pièce rapportée amovible (74) qui est ajustée à ladite chambre et présente un passage traversant (75) mettant en communication l'orifice d'admission (12) et la périphérie de l'organe doseur rotatif (27) de sorte que le volume effectif de ladite chambre (48) est réduit au volume du passage (75). Par conséquent, si le mécanisme de dosage incorpore le dispositif connu de ligne de tram du type à volet obturateur dans lequel un volet (24) sert à fermer l'orifice d'admission (12) du boîtier, la quantité de graines retenue dans la chambre à l'intérieur du boîtier est réduite, de même que la longueur du trajet ensemencé après la fermeture du volet. Le mécanisme doseur peut incorporer également un dispositif de tram comprenant un organe de volet arqué (84).

    摘要: A sliding contact bearing, especially an aircraft landing gear trunnion bearing, comprises two bearing members (1, 3) composed of titanium or titanium alloy with cooperating sliding surfaces (2, 4), a first one of which is chromium plated and the second one of which is coated with nickel and fluorocarbon polymer. Preferably, the nickel coating is applied by an electroless plating process, and the fluorocarbon is infused into pores in the nickel plating. Preferably, the nickel and fluorocarbon coating is 0.025 to 0.041 mm thick, and has a hardness in the range 750-1000 VPN.
