Abstract: The cylinder may be an aircraft landing gear axle. The items may be pick-ups the sense axle deformation. A ring (30) for supporting the pick-ups is made of highly resilient material. It is initially of such a size that its cylinder-engaging surface overlaps the cylindrical surface it is to engage. The ring is then deformed by urging at least two points (34 to 37) around its circumference to increase the degree of overlap. While maintaining the deforming force on the ring, its cylinder-engaging surface (31) is machined so that there is no longer any overlap, and still maintaining the force, the ring is engaged with the cylinder. The force is then removed. The said points move resiliently away from the cylinder, but intermediate points are consequently resiliently urged into contact with the cylinder. The contact is smooth and progressive, thus avoiding the kind of stress concentrations that could reduce cylinder life by fatigue, etc.

Abstract: This invention relates to mounting porous ceramic material to metal surfaces. The metal surfaces may either be flat surfaces or tubes. The ceramic material is held onto a perforated metal sheet by screwed-in spiral springs. The perforated metal sheet acts as a holding device and is located adjacent to a metal surface. The invention provides for porous ceramic insulation which is conveniently mounted with relation to the metal surface. Spiral springs absorb the stresses which occur during use.

Abstract: A method and an apparatus for forming a tube from a flat tape, more particularly for forming a shielding tape around a cable core, is disclosed. The tape is moved longitudinally along a straight path and simultaneously deflected laterally from a flat to a circular configuration around a mandrel, and the center of the tape is stressed over an eccentric ring attached to the outside surface of the mandrel in substantially inverse proportion to the stretch imparted to the tape during forming of the tube.

Abstract: The assembling of integrated circuits takes place in a welding post in which a film bearing circuit units advances step by step. Each integrated circuit is brought into the welding post by a rotating platform driven step by step in synchronism with the film. The integrated circuits are loaded in a loading post angularly separated from the welding post and very slightly separated from the exact position they should occupy following their transfer to the welding post. The position error is corrected in an alignment post by simply sliding the integrated ciruit over the platform surface. Thus three operations may be simultaneously performed (loading, alignment and welding) on three individual integrated circuits.

Abstract: An improved process is disclosed for forming a series of electrically conductive path through-holes in a dielectric layer which is sandwiched between two electrically conductive layers by applying pressure to conductive overhangs in a conductive layer through and elastomeric surface.

Abstract: A machine of modular construction having a framework onto which a plurality of removable stators is mounted. The stators are fixed relative to rotors which fit within openings in the stators. The rotors are keyed to a central axial shaft which provides rotary power so that the rotors can rotate within the fixed stators. Each rotor has a number of radially extending blades having a forward edge carrying a knife, while the stator has similar radially extending blades and knives confronting the rotor's knives in a material shearing relationship. A modular stator is jointed for disassembly allowing access to both rotor and stator knives while the apparatus is still mounted on the framework.

Abstract: The manufacture of a cylinder, particularly for use in sugar mills, which has an exterior surface defining circular grooves of a cross section having the shape of a triangle, each triangle having an apex at a bottom of the groove in a respective transverse plane extending substantially perpendicularly to the axis of the cylinder, and the bottom of each groove being in communication with longitudinal channels extending substantially parallel to the axis in the cylinder, is simplified by inserting plugs into radial channels in the cylinder in a plurality of the transverse planes before making the circular grooves which are cut into the plugs into the inner ends of which are formed circular slots of sufficient length to connect the grooves to the longitudinal channels.

Abstract: A hand operable tool (10) used in installing pistons and piston rod assemblies (PR) into an engine block (EB) includes magnets (170, 172,232) for securing the device to the engine block and engine dowel pin receiving holes (190,226) for receiving cylinder head dowel pins (200) to accurately and precisely orient and position the tool with respect to an engine block cylinder bore. A method of installing pistons and piston rod assemblies into an engine block utilizing the hand operable tool is also disclosed.

Abstract: A cable termination apparatus (90) for use in locating and terminating an electrical cable (10) of the twin-axial type to an electrical connector (50), the cable having a pair of insulated wires (20,30) having inner conductors (22, 32), the apparatus being characterized by as comprising a body (91) of conductive material including a passage (95) for receiving and locating one of the wires (30) and a radial slot (96) for receiving and locating the inner conductor (22) of the other wire (20), the passage (95) extending through the body and having a generally frusto-conical wire entry portion, (97) the slot (96) extending axially inward from one end of the body and intersecting with the frusto-conical portion (97) to provide stress relief to the conductor (22) when terminated within the slot (96) by solder (98).
