Abstract: A linkage for transmitting torque includes a stationary member, a movable member rotatably mounted to the stationary member, an input link having one end rotatably mounted to the stationary member and a second end connected to a linear actuator and a coupler link. The coupler link is connected to the second end of an output link, preferably integral to the movable member. The moment applied to the input link by the linear actuator is transferred through the coupler link to the output link, or movable member. The angle of rotation of the output link is greater than the angle of rotation of the input link.

Abstract: A support stand for a camera or other optical device comprises a head portion supported by support legs comprising first and second telescopically related tube portions, the inner tube portion forming the upper part of the respective leg and the outer tube portion forming the lower part. A fixing device for locking the tube portions of each leg relative to each other comprises an actuating member, a connecting rod and a clamping arrangement connected to the actuating member by the connecting rod and comprising at least one clamping cone member and at least one pressure element. The actuating member is carried on the inner tube portion in the vicinity of the support head portion of the stand. Actuation of the actuating member causes the pressure element to be expanded by displacement of the cone member until the pressure element bears against the inside surface of the outer tube portion, thereby to secure it in position relative to the inner tube portion.

Abstract: A single-lever control lockout for a boom and bucket control lever. The lever is selectively movable in both fore-and-aft and side-to-side directions to control the lowering and raising of the boom and the roll back and dumping of the bucket. A cover encloses the control valve and the control lever extends through an opening in the cover. A lockout is slidably attached to the lever and is movable within the cover opening between a locked position where the lockout engages the cover, and a free position where the lockout is spaced from the cover thus allowing free movement of the lever in all directions.

Abstract: Method and apparatus for securing abrasion resistant members to metallic surfaces to line the metallic surfaces for protection against wear is disclosed. The abrasion resistant members include an aperture therein having a taper in the bottom of the aperture. An end weldable stud of length less than the thickness of the abrasion resistant member is welded through the aperture to the metallic surface to be lined. A cup shaped spring retainer clip having side walls of dimension greater than the aperture and a stud engaging aperture of dimension less than the diameter of the stud is driven over the stud through the aperture of the abrasion resistant member into engagement with the taper of the aperture of the abrasion resistant member to draw the abrasion resistant member into firm securement with the metallic surface. An abrasion resistant plug is secured within the aperture of the abrasion resistant member following installation.

Abstract: The present invention relates to a fast connection with radially acting bolt-locking having a groove in the male element and a bolt in the female element that can receive an axial displacement and whose rear flank when locking engages in the groove of the male element, the bolt being urged into locking by a spring. According to the invention, at least two balls mounted with free radial play in the body of the female element are interposed between at least two points on the perimeter of the bolt symmetrical to the axis of thrust of the spring and a longitudinal ramp embodied on the inner surface of a sliding ring. The invention is applicable to fast connections for piping.

Abstract: A wire coupling device for connecting a displacement-transmitting wire therein is formed by engagement of two wire engaging members, wherein a first engaging member is entered through pivotal holes and then a second engaging member is inserted into a hollow cylinder of the first member, thereafter the two members are circumferentially turned to coincide respective notched grooves, thus the wire coupling device is formed. To the formed device, a wire terminal nipple is connected to serve as a wire coupling in a brake system of a bicycle, wherein the first member and the second member are integrally engaged and are adapted to turn in pivotal holes. Further the invention prevents possible disengagement of the connected nipple by way of turning the two engaged members relatively for about 180 degrees to cross over the grooves and openings provided on the members so that the nipple is enclosed in the wire coupling device.

Abstract: A coupling 10 for connecting an elongate first member 12 to a second member 14. The first member 12 is provided with external radial fins 16. The second member 14 defines a recess provided with a number of internal radial fins 20. The first and second members 12,14 and their fins 16,20 are sized such that the first member 12 can be positioned within the recess of the second member 14 with each fin of each member extending between two corresponding fins of the other member. At least one wedge 24 is positioned in the space intermediate each set of opposing fins 16,20. The fins 16,20 and wedge 24 are configured such that biasing the first member 12 in a first axial direction relative to the second member 14 causes the wedge 24 to lock the fins 16,20 together, preventing movement of the first member 12 in the first axial direction. The present coupling 10 can be used to support the members 12,14 under either a tensile or compressive axial loading.

In this actuator, the drive motor is mounted within the housing in a hidden position. There is a single control slide for keeping normally respective wire cables at their neutral position for keeping in turn the locks in their locked position. There is provided within the housing a three stage reduction and reversely accelerating gearing between the drive motor and the control slide. The first stage includes a crown gear, while the third stage includes rack teeth which is united rigidly with the control slide.

Abstract: A draining well (2) extending downwardly from the bottom (3) of an underground cavity for storing liquefied gas under pressure has an upper portion (9) of large area and a lower portion (10) of smaller area. The volume of the upper portion is sufficient for filling a service tube (5) with water up to its hydrostatic equilibrium level. This enables the depth of the draining well to be reduced and thus makes such a storage facility cheaper to produce.

Abstract: A shaft assembly (11) having a spline (16) with an anti-backlash device operable due to centrifugal force to engage both sides of internal spline teeth during rotation. The spline (16) includes a main force transmitting portion (18) and a moveable spline sleeve (22) which during operation engages the side of teeth opposite the side engaged by the main force transmitting spline. Spline sleeve (22) rides on helix member to move slightly circumferentially as it is moved axially by a centrifugal force actuated member. A bar which is pinned to the spline (16) has one end which moves radially outward due to centrifugal force as the spline (16) is rotated and another end which engages and moves the spline sleeve (22) axially. When the spline sleeve (22) is moved, the splined end on the shaft assembly (11) is locked or wedged into engagement with the mating internal spline (14).
