Abstract: The invention relates to a displacement device for the horizontal displacement of heavy loads, especially of derailed rail vehicles or the like, having a lifting cylinder and a preferably hydraulically driven displacement mechanism, which allows the position of the load raised by the lifting cylinder to be varied, the lifting cylinder (2) being borne by a slide (6) which is horizontally movable, preferably in two opposite directions, the slide being disposed displaceably on the surface of a support and the piston rod (11) of a displacement cylinder arrangement being fixedly connected to the support without the one end of the piston rod (11) being latch-locked to the support in a displacement-dependent manner.

Abstract: A so-called rescue spreader is constructed with a pair of replaceable jaws that are mirror images of one another and are operatively positioned back-to-back. Each jaw is generally a triangle having a back side and a front side, with both sides extending from a base and converging at a tip where the sides define an included angle of approximately 20.degree. to 30.degree.. Corrugations on the back side are provided to reduce slippage. The front side along its half length extending from the tip is provided with a plurality of teeth and a circular cam is provided along the other half length of the front side.

Abstract: A shackle-type connector for the rapid attachment of a round-linked chain to an external device, such as hydraulic rescue equipment. The connector includes a body having an attachment opening which is capable of removably receiving the device, to attach the connector thereon. The chain can be extended through a chain passage hole in the body of the connector. A holding slot communicates with the hole through a transition region. A securing nose defines a chain passage channel in the transition region. The chain can be drawn through the chain passage hole, and a link of the chain is then slid over the securing nose, through the chain passage channel and into the holding slot, whereby the surrounding links, which are rotated with respect to the link in the holding slot, cannot slide into the holding slot. Thus the securing nose secures the chain in the connector.

Abstract: A stripping device for enlarging an opening in sheet material and possibly for initially forming and then enlarging the opening. A hydraulically operated cylinder has a cylinder housing around it. A piston in the cylinder is connected to move a shoe that is guided on the cylinder housing. A clamping jaw is attached to the cylinder housing. An axially displaceable stripping jaw is connected to the piston either by a rod on the piston or that jaw is attached on the shoe and moves with the shoe. The shoe may have a plurality of spaced attachment points for the stripping jaw. There may be an extension of the piston on which the stripping jaw is carried or on which an additional sripping jaw is carried. There may be an extension of the cylinder housing on which an additional clamping jaw is carried.

Abstract: An anchor assembly includes an anchor bolt or stud and an adhesive material for securing the bolt in a prepared borehole. The adhesive material consists of at least two required components which, when mixed together, harden to fix the bolt within the borehole. Of the two required components, one is located within a cartridge and the other is placed on the shank of the anchor bolt and can be enclosed within a destructible sheath. By driving the bolt into the cartridge the components are mixed. Either a mixture promoting material can be included in the cartridge or mixture promoting members can be associated with it to assure the component is stripped from the bolt and adequately mixed with the component in the cartridge.

Abstract: In a straddling dowel or expansion anchor assembly, a threaded bolt or stud has a head or nut adjacent one end for securing a member onto a support structure. The bolt is threaded into one end of a sleeve-like member and a threaded projection extends axially from the other end of the member with the projection extending axially through an expansion sleeve. A spreader is threaded onto the outer end of the projection for use in expanding the expansion sleeve. A device interconnects the bolt or stud and the sleeve-like member so that rotation of the bolt is transmitted to the sleeve-like member for pulling the spreader into and expanding the expansion sleeve. When a minimum anchoring value of the anchor within a borehole is achieved, the interconnection is disengaged. By continued rotation of the bolt or stud the member can be secured to the support structure with the interconnecting device being completely enclosed within the anchor structure.

Abstract: In a straddling dowel or expansion anchor assembly a spreader is threaded on one end of a bolt so that by turning the bolt the spreader is pulled into an expansion sleeve for spreading it into anchoring contact with the surface of a borehole. The opposite end of the bolt has a shoulder provided by a head or nut. Between the expansion sleeve and the shoulder, a yielding member laterally encloses the bolt and yields at least when a minimum anchoring value of the expansion sleeve has been reached. The yielding member affords a visible indication that the minimum anchoring value has been achieved. A washer is positioned adjacent the shoulder on one end of the bolt. Before the expanding action, the washer is spaced from the shoulder on the bolt by the yielding member or by a separate member, however, as the minimum anchoring value is achieved the washer is displaced relative to the member which spaces it from the shoulder, into contact with the shoulder.

Abstract: System for journalling a high speed rotary shaft in which a spherical fluid dynamic cap bearing is adapted to receive an end of the shaft. A magnet arrayed in the vicinity of the cap exerting a force axially on the shaft. The shaft is provided with magnetic material cooperation with the magnet, so that that the shaft is drawn and/or pushed into the bearing.
