Title: Friction welder having a drive which produces orbital motion
Inventor: SNYDER EDWARD A
IPC: H02K41/06
Filed: 1991-12-23
Abstract: An electromagnetically actuated friction welder produces orbital motion at interfaces between parts (usually of thermoplastic material) to bond the parts by fusion generated by friction. This welder can also be operated alternatively to produce reciprocating vibratory forces thereby providing flexibility as to the selection of an orbital or reciprocating mode, depending upon the joint to be welded. The velocity of motion is controllable preferably around the resonant frequency of the driven structure by adjusting the frequency of the AC power which operates the electromagnetic drive motor of the welder. A plate which carries one of the parts to be welded and which is driven is flexurally mounted for movement in an orbital plane or planes containing the interfaces without substantial tilting by an array of stiff members, such as rods, located around the drive motor, attached to the plate at one end and to a tubular structure at the opposite ends thereof. The tubular structure is desirably attached to a massive support carried by the frame of the welder.

Abstract: This invention concerns a process for the casting of anchors (2) meant for the mooring of floating oil producing and/or drilling platforms, for which an anchor laying craft (1) is used, whose general arrangement consists of a deck with wells (3) for anchors, a capstan (4) for dealing with chains (5), cable drums (6) of an improved kind, lockers (10) for the stowing of chains built into the underside of the deck of the craft, which are led by a capstan from such lockers or back to them, along hawsepipes (11), and drums (12) for winding cables, mounted on a bed (13). When a floating platform is being moored, an improved laying device is used which prevents any slipping or dropping after each platform chain has been fastened to the previously laid line whenever the latter has to be lowered to its place in the sag. The invention also provides an improved line fisher.

Abstract: In a combination of multiple concurrently-executing database management systems which share data storage resources, efficient lock processing for shared data is implemented by hiding from a global lock manager the distinction between transaction-interest and cache-interest locks that are processed at the DBMS level. The local lock manager of a DBMS, in response to a request for either type of lock, may issue a request to the global lock manager for a system-level lock without disclosing to the global lock manager the type of lock requested of the local lock manager. After receipt of the system level lock, the local lock manager can grant either transaction or cache interest locks locally on a data resource if the combined mode of locally-held locks on that data resource is greater than or equal to the requested mode.

Abstract: Disclosed are method and apparatus for establishing a Door Dwell Time for an elevator car. The method includes the steps of (a) accumulating, over a first interval of time, a total amount of time that expires between a time when a hall call is received to when an elevator door of the elevator car opens in response to the hall call; and, at the end of the interval of time, (b) determining an Average Waiting Time (AWT) by dividing the total amount of time by a number of hall calls that occurred during the first interval of time. The method further includes the steps of (c) comparing the AWT to a first AWT threshold value; and, if the AWT exceeds the first AWT threshold value, (d) decreasing the elevator car Door Dwell Time (DDT) by a time increment so as to obtain a revised DDT for use during a second time interval. If the AWT does not exceed the first AWT threshold value, the method further includes the steps of (e) comparing the AWT to a second AWT threshold value; and if the AWT is less than the second AWT threshold value, (f) increasing the elevator car DDT by the time increment so as to obtain a revised DDT for use during the second time interval.

Abstract: The invention relates to a rear seat arrangement for buses having at least two rear seats which each have a seat cushion with seat cushion frame which can be moved forwards in the direction of travel by means of a rail guide and a backrest which can be folded down when the seat cushion is moved forwards and is connected in a swivellable fashion to the frame of the seat cushion. In order to provide a rear seat arrangement which is independent of the installation conditions in the vehicle and can be transferred rapidly and with a single handle into a folded-down position of the backrest which clears the emergency exit, the backrests are each connected to a guide rod via a lever linkage, the end of the said rod which is at a distance from the lever being capable of being displaced together with the frame of the seat cushion and being blocked after a predetermined displacement path in the direction of travel. The lever linkage is constructed in such a way that if the frame of the seat cushion continues to move, the folding-down movement of the backrest can then be forced. The locking devices provided at the rear seats to lock them in a fixed position are coupled to one another when a handle is actuated in such a way that all the locking devices are released. A displacement force can then be applied to the frame of the seat cushion via the handle. <IMAGE>
