Abstract: A container forming apparatus to form fluid filled containers from a tube of flexible packaging material includes a fluid delivery conduit to deliver fluid into the tube. A heat sealing mechanism receives the tube and forms spaced seals across the tube between which fluid is located. The seals are formed in a downstream to upstream succession and are non-orthogonal with respect to a longitudinal axis of the tube. Hydraulic equalization supports associated with the heat sealing mechanism support the tube indirections generally orthogonal to the longitudinal axis adjacent the seals as the seal is formed.

Abstract: The present invention relates to improvements in the operation and construction of roof bolters or roof bolt installation apparatus. The improvements comprise a roof bolter constructed so that the critical moving parts of its timber jack, feed frame, feed carrier and rotational unit are comprised of a rod and sleeve construction. Such construction allowing the protection of surfaces. The construction also includes feature of a spaced apart rod and sleeve construction which allows motive power units to be housed within the confines of the timber jack and feed carrier. The spaced apart arrangement also provides stability to the roof bolter.

Abstract: For selective operation in a Diesel mode and a pressure air mode a Diesel type pile hammer is additionally equipped with a pressure air accumulator, which is connected to the working space of the cylinder by a servo valve.

Abstract: A hydraulic hammer having an improved buffer assembly is provided. The hydraulic hammer includes a housing, a top cover plate connected to the upper portion of the housing, a hammer assembly installed in the housing, and a buffer assembly for supporting the hammer assembly, installed between the top cover plate and the hammer assembly, in which the buffer assembly includes a top buffer contacting the upper portion of the hammer assembly and formed of an elastic material for absorbing impact, and a sliding plate is disposed between the top buffer and the top cover plate. The hydraulic hammer reduces the repeated banding stress applied to the hammer assembly.

Abstract: Supporting clamps for a tool such as, for example, a pile driver machine are used to tilt a machine support relative to a horizontal plane. The clamps include a pair of jaw elements one of which is received on a pivot and the other of which has a pair of parallel spaced pistons. The clamp jaw elements gird a fixed reference device to support the tool securely for subsequent operations. Different pressures applied to the two pistons causes the clamp to tilt about the fixed reference device, and thereby to tilt the tool to which it is attached. The difference in pressure is controlled to rotate the tool as desired. In a second embodiment of the invention, the desired angle is established by controlling an angle of a backup surface, and applying equal pressure to the two pistons. The fixed reference device is driven into the angled backup surface to establish the desired tilt angle. In a further embodiment, one piston is disposed at each side of the gap. The two pistons are spaced apart along the gap.

Abstract: A tool, in particular a power screw driver, comprises an output shaft which is rotatably mounted in a housing and is driven by a motor. The output shaft extends substantially coaxially to a longitudinal axis of the housing. In order to improve a tool of the type described in such a manner that the tool can be held comfortably, in controlled manner and with little force, a grip sleeve which is rotatable relative to the housing is fitted over the housing, and at least one damping device that counteracts a pulse-like rotation of the grip sleeve relative to the housing is disposed between the housing and the grip sleeve.

Abstract: A clinch mechanism in a stapler in which legs of a staple penetrating a work are bent in a bending groove, comprises: a pair of right and left movable clinchers being movable in the bending groove in an operative direction, a pair of receivers formed symmetrical with a center of the bending groove so as to receive the legs of the staple which have penetrated the work, the receivers having guide slopes inclined towards the bending groove, and wall surfaces on the sides of the center of the bending groove wherein the wall surfaces are continuous to ends of the guide slopes which are on the sides of the bending groove such that the wall surfaces are in parallel with the operative direction of the movable clincher.

Abstract: A hydraulic ramming apparatus including an apparatus body (14) having a cylinder bore (23) and a guide bore (24) that are successively formed to each other in the apparatus body (14). A piston (30) is slidably inserted into the cylinder bore (23) so as to be reciprocable within the cylinder bore (23). An upper pressure-receiving chamber (31) is defined at an upper end portion side of the piston (30), and a lower pressure-receiving chamber (32) is defined at a lower end portion side of the piston (30). A ramming tool (19), having a rod body (35), can be detachably inserted into the guide bore (24). Also, a mechanism for moving the rod body (35) is provided so as to follow upward movement of the piston (30).

Abstract: The present invention generally relates to severing a running material web in a folding apparatus of a web-fed rotary printing press. In one exemplary embodiment, a severing element is moved in the traveling direction of the web with a speed which is substantially equal to the speed of the running web and is simultaneously moved across the width of the web in a substantially lateral direction. The severing element can be a sled with a blade, a laser source, a high-pressure fluid jet or a heated wire. The severing element is received and guided by a guiding rail coupled to a pair of endless parallel transport chains.
