Abstract: The invention provides a releasable connector comprising a male part presenting four mutually inclined faces forming a tetrahedral wedge, and a female part presenting three walls for mating with the faces of the male part when the male part is inserted therein. A locking device is mounted on one of the two parts and applies a locking force, urging the wedge into intimate contact with the female part to lock the male part in position. The locking means is movable to a release position in which it frees the male part for insertion and withdrawal in a direction transverse to the face. The mutual inclinations of the three faces are sufficient to avoid jamming of the connector.

Abstract: A portable and foldable stand for musical instruments includes a pair of spaced apart supports each including a tubular main leg having a pivot collar, a brace leg, a brace, a pin for joining one end of the brace to the brace leg, and a latch for releasably attaching the brace to the main leg. The brace leg is pivotally linked at one of its ends to the pivot collar of the main leg and is joined to one end of the brace by the pin. The other end of the brace is releasably attached to the main leg by the latch means. A pivot is joined to the main leg, and an upper segment is joined to the pivot means. At least two cross members are provided each one including a releasable clamping sleeve for releasably clamping each cross member to each support. The clamping sleeve is releasably clampable and slidable on the upper segment and the pivot, thereby linking the pair of supports.

Abstract: Anti-rotation lock asembly includes a male threaded member that may be releasably locked in any desired axially adjusted position relative to a mating female threaded member by means of one or more wedge keys that are forced axially into notches in an end face of the female threaded member and radially against flats or keyways on the male threaded member. Surrounding the male member is a key retaining ring which retains the wedge keys on the male member when the wedge keys are disengaged from the female member to permit relative rotation between the male and female members for adjustment of the male member in or out relative to the female member. The wedge keys are retained in radial slots in the retaining ring which prevent relative axial movement between the wedge keys and retaining ring while permitting limited radial movement therebetween.

Abstract: We are dealing with a mechanism for clamping a second machine part 4 which is supported movably with respect to a first machine part 2. A clamping bar 28, which extends in the direction of movement is arranged on the second machine part 4, on which clamping bar can be clamped a clamping member 32 which is supported freely movably in directions transverse to the direction of movement of the first machine part, but otherwise clearance free. Since the clamping member 22 is as a whole freely movable in directions transverse to the direction of movement, no reactive forces whatsoever are created in the direction of movement during the clamping operation.The inventive clamping mechanism is preferably used in feed-movable spindle sleeves (tail spindles) in order to assure a secure clamping in an axial direction and in a peripheral direction, without producing forces which act transversely to the spindle axis.

Abstract: A protective device protects a platform installed in the open sea against the impact of floating objects such as icebergs, ice formations, or ships. A massive protective body surrounds the platform to be protected and has a bottom with inclined bearing surfaces. The body is movably supported on large bearings having inclined bearing areas that slidingly engage the bearing surfaces. When the protective body is struck by a floating object the kinetic energy of the impact pushes the protective body upwards on a portion of the inclined bearing areas and is transformed into potential energy of the elevated body. The protective body is able to thrust the floating object away from the platform as the body moves downwardly to its original position as its potential energy is reconverted to kinetic energy.

Abstract: The transmission has a housing enclosing an annular output gear with a drive member rotatably mounted coaxially therein. A drive gear carried by the drive member engages the output gear. A lug plate carried by the drive member interacts with a guide plate radially movable with respect to the housing to change the relative path traveled by the lugs and thereby the rotational ratio between the input and output gears. Transition between ratios is smooth and continuous over an almost infinite range of ratios.

Abstract: In a situation where animals, such as beavers, attempt to flood lands by blocking culverts or constructing dams across waterways, a device is used to maintain a constant flow of water through the dam or culvert. An elongated pipe or culvert with a downwardly directed opening distant from the culvert or dam is used. On the end of the pipe closest to the culvert is a gate which prevents animals and debris from passing through but allows for the smaller elongated pipe to communicate with the culvert. The beaver instinctively attempts to dam the gate area rather than dam the underwater opening of the elongated pipe, and thus is unsuccessful in stopping the flow of water.

Abstract: A molded, one-piece adaptor for concentrically connecting a steering wheel and a steering wheel shaft is disclosed. In particular, the adaptor is useful when the steering wheel shaft has a tubular form, but the adaptor may be readily modified in order to connect to a steering wheel shaft having a rod-like form. The adaptor comprises an upper portion and a lower portion. The upper portion has a mechanism for meshing with the steering wheel. The lower portion engages with the steering wheel shaft. If the steering wheel shaft is tubular, the steering wheel shaft slips over the lower portion which has a plurality of tapered ribs which are spaced around and extend axially along the lower portion. These tapered ribs tend to take up any variation in tolerances so as to reduce the rocking between the steering wheel and steering wheel shaft.
