Abstract: ABSTRACT OF THE DISCLOSURE           A process for reducing the waiting-on-cement (WOC) time assoc-iated with the cementing of a casing string in an oil well involving the specific improvement of pumping into the well a highly retarded cement slurry containing a dispersed encapsulated accelerator, such as calcium chloride or anhydrous sodium metasilicate, wherein the encapsulating material is specifically selected such that it will melt at a tempera-ture above the bottom-hole circulating temperature but below the bottom-hole static temperature of the well to be cemented.  Petroleum-derived waxes and petroleum-derived waxes in combination with vinyl resins, such as wax-compatible copolymers of ethylene and vinyl acetate, are particu-larly suitable as the meltable encapsulating material exhibiting excel-lent strength and abrasion resistance as well as serving as a moisture barrier.  The improved process is particularly useful in cementing deep hot wells.

Abstract: ABSTRACT OF THE DISCLOSURE         An enveloper system is disclosed which fabricates envelopes around a series of continuously moving single or multiple page letters.  Very accurate registration or synchronization of the envelope web blank and letter at high speed is achieved by supplying envelope blanks from two separate stacks of envelope blanks to a pair of Bernoulli plates from which the blanks are fed alternately to continuously running take-away rollers.  The accuracy of registration or synchronization is achieved by the fact that the alternate feeding takes place initially at only half the speed at which the letters are moving through the system.

Abstract: -39-                    W.E. 47,863 Abstract A servicing machine for a steam generator is accurately set up in the generator channel head with a pivoted arm mounted for rotation in a plane parallel to the tubesheet.  The angular position of the arm, the longitudinal position of a carriage mounted on the arm and the vertical position of a platform on the carriage are remotely controlled to maneuver a probe used in mapping the precise location of the thousands of holes in the tubesheet.  Various operations are then performed at each precise hole location by tools carried by the arm mounted carriage to prepare for installation of new tubing.  The operation of a pair remotely controlled pivoted arms, one on each side of the channel head divider plate, is coordinated to automatically position the ends of U-shaped tubes in corresponding holes in the tubesheet on opposite sides of the divider plate and to secure the same in place.

Title: Process and apparatus for balancing a rotating body
Inventor: MAUS OTFRID
IPC: G01M1/16
Filed: 1979-10-16
Granted: 1982-06-15
Abstract: ABSTRACT OF THE DISCLOSURE   This invention relates to a process and an apparatus for balancing a body of rotation in two parallel balancing planes disposed perpendicular to the rotational axis of the body.  A slotted plate disposed substantially per-pendicular to the axis of rotation of the body conducts the rotary and trans-latory vibrations to separate transducers.  The slots essentially divide the plate into an outer frame and central portion, which are connected by narrow linking strips.  The rotary vibrations are transmitted by linking strips which are stressed in bending, where as the translatory vibrations are transmitted by linking strips which are stressed in tension or compression.  Unwanted force factors are eliminated by interposing members between their source and the foundation, such as by mounting the rotating body and slotted plate upon springs, which in some instances may be vertically disposed.

Abstract: ABSTRACT            "Diagnosis Of Engine Power and Compression Balance"     This disclosure relates to a system for analyzing the performance of a reciprocating piston, internal combustion engine such as a diesel engine.  Sensors are connected to the engine, which respond to various operating parameters, and signals representing the parameters are transmitted to computer processing equipment.  A speed sensor responds to the movement  of an engine part such as the teeth of the engine fly-wheel ring gear, and the processor calculates a function representing the change in the instantaneous engine kinetic energy.  The kinetic energy change data are accumu-lated during an engine acceleration run and again during a deceleration run.  The signals from an engine cycle event sensor are processed to indicate the firing intervals of the cylinders and thereby to correlate the engine acceleration and deceleration data.  The changes in kinetic energy during the cylinder firing intervals are measured during engine acceleration, and the kinetic energy changes are again measured during deceleration, the two sets of measurements being at substantially the same engine speed.  For each cylinder, the measurement on deceleration is subtracted from the related measurement on acceleration, to obtain the net work produced by each cylinder.  A similar procedure may be followed to obtain the work done over segments of each firing interval, to thereby check the compression balance of the cylinders.

The hot melt adhesive layer has a lower modulus of elasticity than the film and is applied in heat-softened condition to obtain strong, uniform adherence to the film.  In a method for applying the adhesive layer wide band of adhesive of predeter-mined thickness is extruded in heat-softened condition into direct contact with selected areas of a moving web of the film. The adhesive is one which has a Ring & Ball softening point lower than the heat distor-tion temperature of the film and during application will not thermally degrade or distort the film.
