Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to mechanical linkages and discloses linkages for constraining relatively large motion of the reference member to be along a reference axis.  The linkage includes two pairs of flexure elements, each flexure element having a vertex end portion and at least one distal end portion.  The flexure elements of each pair are connected so that their corresponding pairs of distal end portions are coupled to each other.  Each of the coupled distal end portions is connected by a rigid link to the corresponding pair of connected distal end portions of the other pair of flexure elements so that the junction of the distal end portions of each coupled pair are separated by a predetermined distance in the direction of the reference axis.  The vertex portions of corresponding ones of the flexure elements of each pair is connected to the reference member.  The two vertex portions coupled to the reference member are separated by the pre-determined distance in the direction of the reference axis.          The vertex portions of the other flexure members are connected to the support member at points separated by the predetermined distance in the direction of the reference axis.  This improved linkage effectively constrains the motion of an element to motion along a reference axis with a relatively large range of motion.

Abstract: CLAD THICKNESS MEASURING DEVICE          ABSTRACT OF THE DISCLOSURE         A system (10) for determining the thickness of a magnetic flux conductive clad material over a magnetic flux conductive base material of different permeability applies an alternating voltage (96) to the primary winding (52) of an incomplete core-type transformer (54).  The secondary winding (40) voltage to primary winding (52) voltage ratio is determined with the material being clad-thickness measured (56) completing the incomplete core (54). The voltage ratio is a nondestructive measurement of the thickness (64) of the clad material.  The preferred embodiment applies a constant voltage alternating voltage power source (18) to the primary winding (52).  This obviates the need to determine the ratio of voltages.  The secondary winding (40) voltage is a direct nondestructive measurement of the thickness (64) of the clad material.  By reference to a particular clad material-base material chart, the clad thickness is read from the scale adjacent the intersection of the voltage induced in secondary winding (40) and the curve (78,80,82,84,86,88,90,92,94) representing the composition of the clad material.

Abstract: ABSTRACT OF THE DISCLOSURE   an exterior surface portion or a metal tube (30) is bonded to a surface portion or a bore (11) in a metal tubesheet (10) by detonating an explosive bonding charge (31) inside the tube (30) adjacent a front face (13) of the tubesheet (10).  The bonding charge (31) consists of nitroguanidine, and is contained within a polypropylene container comprising a cup structure (21) and a header structure (22).  The cup structure (21) forms a receptacle  for the bonding charge (31), and positions the bonding charge (31) at the proper depth within the tube (30) to achieve the desired bonding effect.  The header structure (22) overlies and shapes the bonding charge (31), and contains a transfer charge (44) and a firing charge (43) for initiating detonation of the bonding charge (31).  A firing assembly for initiating detonations of firing charges (45) in tubes (30) arranged in a plurality of linear arrays comprises a corre-sponding plurality of firing rails (24) and an initiation rail (27).  Each firing rail (24) is secured to the header structures (22) of a corresponding linear array of bonding charge containers, so that a linear charge (25) secured to the firing rail (24) can initiate detonation in sequence of the individual firing charges (25) of the corresponding linear array.  An initiation rail (27) crosses each of the firing rails (24), so that a linear initiatin charge (25) secured to the initiation rail (27) can detonate each of the linear charges (25) on the various firing rails (24) in sequence.

A substantial weight mass is disposed in the housing and is responsive to centrifugal force such as occasioned by a vehicle turn, particularly an abrupt turn, to cause displacement thereof axially of the housing.  The device further comprises a piston at each end of the housing and means associated therewith for biasing the piston to a normal rest position, said piston having means permitting fluid bleeding between opposite sides thereof to enhance stabilizer action.

Abstract: ABSTRACT     The resistance to weld toe corrosion, exfoliation corrosion, and stress corrosion of joints welded from parent portions (of aluminium-zinc alloys containing magnesium) is in-creased by a pre-fusion application of a coating, comprised by a similar aluminium-zinc alloy containing less magnesium, the coating being applied by a hot-spraying process so as to coat at least the region of mutual interface and the intended weld zones.  The utility of the method mainly lies in the increased life of the weld, ie the prevention of its degradation.

Abstract: MULTIPLE OFFSET BOOM EXTENSION Abstract of the Disclosure A side stowable swing-around boom extension is pinned on the nose of a telescoping crane boom in a first use position nearly coaxial with the center line of the boom but tilted or offset therefrom at a small angle. Two larger angularly offset use positions of the boom extension are obtained with convenience and with complete safety while the crane boom and boom extension are at a near ground level position. Two slotted tension links are connected between the upper side of the boom extension and the boom nose and are allowed to support the boom extension in either of two major offset use positions automatically as the crane boom is elevated from he near ground level position. In such operation, the boom extension is allowed to rotate around the axis of its lower side pivotal connection with the boom nose while its upper side connection with the nose is released. The lower side connection is biased toward a position corresponding to the nearly coaxial use position of the boom extension.
