The angular relation of a pair of pipes to be connected can be changed then fixed in the required angular position. The angular position of the fixed pipe axis cannot be changed without intentional rotation of wedge-shaped parts of the assembly.

A connection device for releasably interconnecting two members (16, 18) preferably a receptacle and its lid, comprising an upper component (1, 101) which is provided with a hook (21, 102) and a lower component (2, 103) and a one- or two-armed lever (3, 104) which is articulated on said lower component and which is provided with a counterhook (15, 105). In order to avoid that the connection device springs open or disengages unintentionally, a snapper (5, 109) is pivotably attached to the end of t...

A cable connection is described. It is particularly suitable for a piezoelectric cable which has a low melting point conductor. The connection is made by inserting a conductive piercing member such as a wire (14) into the conductor (4), so as to leave a portion of the piercing member extending from the cable. The piercing member (14) is then heated to the softening temperature of the cable conductor (4) to allow local softening of the conductor. The result, on cooling, is a solder joint between ...

A hinge connection comprises a one-piece hinge part of synthetic plastic material and a separate part to which the hinge part is fittable. The hinge part comprises an elastic joint film forming a joint axis and stiffening strips extending on both sides thereof parallel to the joint axis and formed by material thickenings. On at least one stiffening strip there are formed two resilient tongues protruding with mutual spacing and in one common plane, on the ends of which tongues there are formed pr...

A connection device is provided including a housing with a chimney for inserting wires to be connected, extended inside the housing, and in which a catch is locked. A plug, having a slotted clip for gripping, pulling and stripping the wires by extrusion of their sheath between the catch and the clip, is driven into the housing. The clip is locked on the housing. The space between the clip and the catch is less than the diameter of the core of the wires.

An improved threaded connection adapted to secure adjacent conduits in a continuous flow conduit forming relationship. The threaded connection employs a tapered or wedge shaped thread with angled or tapered thread load flanks to obtain superior mechanical strength by controlling stress levels in the connection. To insure proper make-up of the connection the dimension of the thread structure is controlled to prevent trapping of thread lubricant during rotational make-up which may produce false to...

In the case of a flange connection for rectangular air conditioning ducts which have four walls, four flange profiles with four rectangular angle-pieces are fitted frame-wise on the end of a duct portion. The flange profiles are in this case subhstantially L-shaped hollow profiles which are in each case fitted onto a duct wall and fixed there with a plurality of spot welds. Problematical is the seal between the inner arm of the flange profile and the duct wall, because by reason of spot welds wh...

Stabilizng arms are applied to an agricultural tractor having a three point hitch with a quick hitch frame. Specifically, a belly plate is added to the frame beams about half way between the front axle and the rear axle. A horizontal frame draw bar extends from the belly plate to a pivot pin mounted by a clamp below the rear axle housing. The stabilizing arms extend from the pivot pin below the axle housing back to a quick hitch frame pin, which is an extension of the quick hitch pin and extends...

A limitedly shiftable overlap connection between two platelike parts, as between a U-rail and a covering or blocking platelet of connection rod fittings in which the parts can be brought into connection with one another through a simple snap plug coupling without the need for riveting or welding.

The invention relates to a flange connection for two components, in particular for containers, pipes or the like, with each of the two components having a flange which can be fastened against one another by fastening means and enclose between them a sealing body gripping over the connecting joint between the two components. Each flange, in its end face facing toward the connecting joint, has an annular sealing chamber which widens conically toward the connecting joint and into which a sealing bo...
