Abstract: A roof support employs an hydraulic piston and cylinder unit as an adjustment device between the goaf shield and the roof-engaging structure. The cylinder unit is mounted to the shield with the aid of a bearing body defining a cup receiving a spherical end of the cylinder. The body also has recesses accessible via offset openings in which journals projecting from the cylinder are located. Locking pieces detachably fitted to the shield block the openings to retain the journals therein yet permit easy assembly and dismantling of the unit.

Abstract: Piston for combustion engines consisting of an upper part forming the piston crown and a lower part forming the piston body. These two piston parts abut via annular contact surfaces in the piston axial direction and are coupled together via a gudgeon pin or a gudgeon pin bushing. In order to arrange such an unscrewed piston in such manner that its upper part need not be constructed to be rigid and heavy as in an articulated piston with pendulum shaft and that the construction of cooling channels between the upper and lower parts is possible without excessive expenditure and the constructional height of the piston can be small, the contact surfaces are mutually prestressed in the direction of the piston axis in that the gudgeon pin bore in the one piston part is arranged to be offset relative to the gudgeon pin bore in the other piston part in the unstressed condition in the direction of the piston axis. In this connection, the offset can amount to 0.5 to 10 parts per thousand of the piston diameter.

Abstract: A peristrophic internal combustion engine with increased power output has greater torque and reduced friction. The distance of rotation between the inertia weights and the crankpins is increased to increase torque. These transposed inertia weights are embodied in top and bottom journals of the connecting rods and in the pistons assemblies. Each piston assembly includes a top piston-ring-holder piston and a lower, bearing piston joined to reciprocate in the cylinder. The lower bearing piston may have a circumferential ring, cylindrical barrel rollers, or spherical ball bearing arrangement contacting the cylinder wall while the upper piston carries the piston rings. The spherical ball bearing arrangement allows lower piston rotation about the piston axis. Inner and outer cylinder liners increase the cylinder operating life and reduce combustion heat loss through the cylinder wall.

Abstract: A piston pin with a bore extending through it. To save weight and to optimize the shape of the pin with respect to accommodating stress, the diameter of the bore is increased to 75 to 90% of the outside diameter of the piston pin and reinforcing ribs are positioned in the bore in the vicinity of the inner edge of each hub.

Abstract: A link joint containing, between two component parts to be connected pivotably, a tension ring placed in corresponding cavities in the component parts extending from a pin, which tension ring, in addition to the pin on which the component parts bear with opposing bearing surfaces, encloses a tension pin which extends fully within one of the component parts and parallel to the pin axis.

Abstract: In a piston and connecting rod assembly for reciprocating piston machines the bending load applied to the piston pin bosses owing to the deformation of the piston pin to an oval shape should be prevented and the weight should be reduced. This is accomplished in that the piston pin is I-shaped in cross-section with wide flanges, the outer surfaces of which are shaped in accordance with an arc of a circle.

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 piston for combustion engines has connecting rod mounting apertures or pin bosses for receiving a gudgeon pin for a connecting rod, which bosses have resilient regions in the form of annular resilient sectors (17, 16) by the formation of slots in the axial direction of the piston. These annular spring sectors can however also be provided on the little end. Upon the occurrence of disturbing oscillations coming from the region of the crank shaft, these are transmitted axially of the resilient annular sectors and suppressed.

Abstract: For lifting loads there is provided an eyebolt with a collar swivelly mounted on a stud so as to freely rotate in a horizontal plane throughout a full 360.degree.. A lifting ring has oppositely disposed pivot pins in swivel engagement with the collar to allow the ring to pivot in a vertical arc as well as to rotate about the stud. The stud in turn is adapted to be anchored in fixed position to the load, whatever the load may be. Enlargements at free ends of the pivot pins serve to resist pulling the pins free of the collar when a heavy lifting force is applied to the lifting ring.

Abstract: A piston pin comprising a tubular body enclosed by end caps, the end caps being secured to the tubular body by an extrusion extending into a recess in the inner periphery of the tubular body, and said extrusion being formed when said end cap is hammered into the tubular body so that an end of the end cap abuts against an annular wall in the tubular body adjacent the recess to force the end cap material into the recess. Preferably, the end cap includes an axial bore, and a transverse bore for communicating between the axial bore and the periphery of the cap, and the transverse bore is positioned so that it communicates with an area adjacent a tapered end portion of the tubular body. In a preferred method of forming piston pins according to the present invention, the tubular body is heated before the plug is hammered into position within the end of the tubular body. Once the end cap has been installed in the tubular body, the end cap and the axial end of the tubular body can be finish machined as desired.

Abstract: A piston arrangement including a hollow piston, a piston pin extending within the piston, an intermediate abutment within the piston supporting the pin between its ends, and a transmission member, e.g., a connecting rod, engaging the pin on each side of the intermediate abutment. The intermediate abutment may be supported by the circumferential wall of the piston, or by the piston head, and may be formed as one piece with the piston. The transmission member may have a forked end for engaging the piston pin, the intermediate abutment being between the arms of the fork. The piston pin may be two separate aligned pins each having an end located within the intermediate abutment. The piston, intermediate abutment, piston pin, and transmission member may all be formed of a ceramic material.

Abstract: In the embodiments of the invention described in the specification, a piston and a connecting rod of an internal combustion engine have opposed approximately semi-cylindrical bearing regions partially enclosing a pin, leaving free gaps between the bearing regions to permit swivel motions of the piston and connecting rod about the axis of the pin. Two symmetrical rings which surround the pin axis retain the bearing regions against the pin. The provision of such opposed bearing regions reduces the oscillating mass of the link joint.

Abstract: In connection with a plunger piston for internal combustion engines, the connecting rod, which is hinged thereto via a gudgeon pin, is laterally guided at its small end by being in abutting contact with the internal faces of the gudgeon pin bosses. For this purpose, there are provided, only in the zone at the level of the gudgeon pin axis, limited contact surfaces between the connecting rod small end and the gudgeon pin bosses. By this means, the influence of deformations of the piston on the guidance of the connecting rod is eliminated to a very large extent.

Abstract: In order to provide a pin for connecting machine parts with one another, which is of optimally light weight, the pin is of a compound structure comprising a core of filler-reinforced synthetic plastics resin and a metallic envelope. As filler there are used quartz sand or carbon fibers. The envelope is preferably seated on the core under circumferential tensile bias. The manufacture of the pin takes place, for instance, by pressing the filler and a matrix resin system directly into a suitably prepared envelope.

Abstract: A device, such as a gudgeon pin, for connecting a piston of a reciprocating internal combustion agent to a connecting-rod comprises at least in part a fibre-reinforced composite material. The device further comprises a metallic sliding bearing having a circular cylindrical external surface. The sliding bearing layer is arranged on the external surface of the fibre-reinforced composite material. A plurality of fibre layers, which run in differing directions, are arranged in the composite material, and the sliding bearing layer is divided in the transition region from a piston to a connecting-rod. The gudgeon pin has alternate layers, in which fibres are arranged orthogonally to fibres in an adjacent fibre layer. The fibres run parallel to the gudgeon pin axis in one layer and orthogonally thereto in the two adjacent layers.

Abstract: A light-weight, high-strength composite pin for use in pin-jointed reciprocating mechanisms and a method of preparation thereof is provided. Basically, the pin has a tubular metal sleeve and an interior fiber-reinforced resin core. At least 50% of the fibers in the core are continuous fibers which are oriented at a predetermined specific angle of orientation ranging, in general, from 0.degree. to about .+-.25.degree.. Indeed, in a preferred embodiment of the present invention, the fibers are cross-plied at an angle of orientation of from about 5.degree. to about 12.degree..

Abstract: The backpack carrier permits a user to bend sideways, forward and backward without impediment. It includes a backpack frame and shoulder harness which is pivotally attached to a hip yoke through a two axis pivot member to permit pivotal movement therebetween about the vertical axis and about the horizontal axis generally perpendicular to the plane defined by the backpack frame. The ends of the hip yoke are secured to a harness locatable about the user's waist through a pivot member to permit pivotal movement of the hip yoke about the horizontal axis in the plane generally defined by the backpack frame.

Abstract: The invention is a new linkage for connecting the piston and the piston actuator in a high pressure pump. All of the compression forces transmitted from the piston actuator to the piston by this linkage will be axial forces parallel to the axis of the piston since the linkage will not transmit forces to the piston which are transverse to its axis. This linkage allows the use of hard brittle materials such as ceramic materials in the piston because any misalignment between the axises of the piston actuator and the piston will not result in bending forces being applied to the piston which would cause it to break.
