Inventor: PANTTILA VAINOE
IPC: F16H57/025
Filed: 1995-03-06
Abstract: A drive gear for a group of cylinders and a method in the drive of cylinders in which the drive gear has a box frame including a front plate, a rear plate, and side plates, and to which box frame, rotational drive is introduced from outside the gearbox through a shaft.  Rotation of the shaft causes rotation of a cogwheel and further, two other cogwheels are rotated which are in contact with this cogwheel, and the drive is transferred to both sides of the gearbox and further to the cylinders.  The box frame of the gearbox is stationarily supported on a foundation which receives the weight of the gearbox shafts and cogwheels and the weight of the box frame.  The load arising from the weight of the gearbox is transferred to the foundation through the box frame of the gearbox.  Two cylinders and their shafts can be operated so that, between the shafts and the gearbox, there is a floating coupling which permits certain angular changes for the shafts of the driven cylinders.  In this manner, torsion arising from faults in the directions of the shafts is not transferred from the cylinders to the gearbox or from the gearbox to the cylinders.

Filed: 1991-09-11
Abstract: A motor control system includes a single, multicompart-ment enclosure mounted on a skid. The enclosure contains a transformer circuit and a motor controller circuit intercon-nected so that only external connections to a power source and a load are needed. When the circuits are energized, access to high voltage motor control components and to field replaceable fuses and output selection switches is prevented by a double interlocking mechanism which operates in con-junction with energizing and de-energizing the transformer. The transformer of the transformer circuit includes a ter-tiary winding disposed radially between a primary winding and a secondary winding. The winding filters electrostati-cally coupled transients. A conventional electrostatic shield is also used so that the transformer is doubly shielded to electrostatic transients. The tertiary winding is connected to one or more capacitors to filter magneti-cally coupled transients. A current limiting fuse, a load sensing fuse and a primary make/break switch are connected in electrical series to the primary winding. Methods for energizing or operating a motor utilizing the primary switch and the load sensing fuse are also disclosed.

Title: Method and apparatus for measuring the distance of a turbocompressor's operating point to the surge limit interface
Inventor: BATSON BRETT W
IPC: F04D27/02
Filed: 1995-04-07
Abstract: A method and apparatus are disclosed for protecting turbocompressors from unstable flow conditions (surge and stall). To accomplish this, it is necessary to easily and accurately calculate a compressor's operating point and its distance from the interface between the surge region and the stable region-this interface is referred to as the Surge Limit Interface. The proximity of theoperating point to the Surge Limit Interface. The proximity of the operating point to the Surge Limit Interface is calculated using measurements of properties throughout the compressor-process system. It is crucial that the calculation be invariant to suction conditions, especially gas composition. Disclosed are three coordinates, Tr (reduced torque), Pr (reduced power), and Ne(equivalent speed). Each of these can be combined with other invariant parameters to construct coordinate systems in which to define the Surge Limit Interface and measure the distance of the operating point to that interface.

Title: Safety Coupling for Rotary Down Hole Pump
Inventor: MILLS ROBERT A R
IPC: F16D43/16
Filed: 1995-08-28
Abstract: A safety coupling for preventing backspin at excessive speeds of a torque transmitting drive powering a drive shaft which stores reactive torque due to torsional stress is disclosed. The safety coupling includes a rotatable driving member to be coupled with a torque producing power source, a rotatable driven member to be coupled with the drive shaft for axial rotation therewith, means for coaxially and rotatably supporting the driving and driven members in relation toeach other, a radial abutment provided on the driving member, and a centrifugal force responsive pawl pivotally mounted to the driven member for releasable engagement with the abutment. The pawl is pivoted from a locking position wherein it engages the radial abutment upon mutual rotation of the driving and driven members to provide a positive driving connection therebetween, to a disengaged position wherein the driving and driven members are freely rotatable relative to each other by the centrifugal force acting thereon when the driven member is coupled to a drive shaft backspinning at a speed in excess of a selected speed. The coupling substantially prevents damage to the torque transmitting drive upon excessive back-spin of the drive shaft and reduces the risk of injury to personnel working in the vicinity of a drive shaft subject to elastic torsion.

Title: Electron beam array for surface treatment
Inventor: WAKALOPULOS GEORGE
IPC: H01J37/06
Filed: 1994-05-23
Abstract: An array of electron beam tubes (152, 156, 158) is mounted on a conduc-tive plate (91, 109, 123) for projecting stripe-like electron beam (163, 164, 165) through air onto a substrate (101) beneath the plate. The tubes each have a narrow beam window (51) formed by a very thin low-Z film layer (73), supported by silicon (71) and sealing the tube against ambi-ent pressure. Such windows produce low beam attenuation and allow low extrac-tion voltages to be used, thereby reducing beam energy which would otherwise be lost by penetration through a surface to be treated. The stripe-like output electron beam segments (113, 115) may be formed into a linear beam track so that the en-tire widthwise extent of a surface, such as a sheet or web (121), may be treated by electron beam irradiation or the beam segments may be formed into any desired composite beam pattern. In another em-bodiment the stripe-like output beam seg-ments may be arranged in an array to treat a circular circumferential surface, such as a cable.

Title: Cylindrical magnetron shield structure
Inventor: SIECK PETER A
IPC: H01J37/34
Filed: 1995-12-21
Abstract: An improved shield structure for use in a sputtering  apparatus  for  depositing  a  film  on  a substrate is disclosed.  The cylindrically shaped shield structure, which extends over the ends of a cylindrical sputtering target, has at least one annular structure extending around an outside surface of the shield.  The annular  structure  is  dimensioned  to  interrupt  or suppress movement of any arc which might otherwise travel across its outside surface.   In a preferred embodiment, the annular structure is a groove capable of trapping any such arc therein and preventing its escape therefrom.    In  another  preferred  embodiment,  the improved shield structure is electrically isolated such that it is prevented from becoming an anode.  In this manner,  the  electrically  isolated  shield  structure inhibits the formation of severe arcs between it and the cathodic target.   Further, with its arc-suppressing annular  structure,  the electrically isolated shield structure inhibits movement of any such severe arcs which might otherwise travel across the shield surface toward the support blocks, the vacuum chamber or other anode.
