Title: Vibration isolator and shock absorber device
Inventor: WASSELL MARK E
IPC: E21B47/01
Filed: 1988-08-10
Granted: 1992-06-09
Abstract: VIBRATION ISOLATOR AND SHOCK ABSORBER DEVICE            Abstract of the Invention:     A vibration isolator and shock absorber system which provides excellent protection to sensors against the deleterious effects of shock and vibration even under severe drilling conditions is presented.  The vibration isolator and shock absorber system is enclosed within an outer cage and an inner yoke.  The cage is attached to the drill collar which takes the full impact of the shock and vibration due to drilling.  The yoke supports the sensor.          Conical disc springs (e.g. Belleville springs) or the like are stacked between the yoke and the cage; and are supported by pairs of upper and lower support rings.          These rings fit together to compress the springs and to allow for axial displacement as well as providing damping.  The pairs of support rings are supported, in turn, between upper and lower elastomeric isolator rings.          The upper elastomeric isolator ring is keyed to the yoke and the cage.  Fluid is allowed to move through the system via orifices in both the elastomeric isolators and the pairs of support rings.  The size of the orifices in the support rings control the amount of damping within the system.  The vibration isolator and shock absorber system of the present invention will dampen severe loads in the axial, lateral and torsional directions.  The system utilizes the drilling fluid as the damping medium for viscous damping (e.g. forcing fluid through orifices in the support rings).  Additional damping is supplied by flexing of the Belleville disc springs, which causes fluid movement, and friction and material damping of the springs.  Radial (lateral) and axial damping is provided by the rubber isolator rings while torsional damping is provided by locking the upper isolator ring to the yoke and cage.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention provides method to take advantage of the exhaust gas pulses in an exhaust system of a multi-cylinder  internal  combustion  engine  to  increase  the volumetric efficiency over the complete operating range of the engine. It solves the problems of other systems which are only able to gain a beneficial effect from the exhaust gas pulses over a limited range of the engine operating speeds, by providing a means of varying the exhaust pipe lengths, combinations,  and  cross-sectional  area  of the exhaust passages of the multi-cylinder internal combustion engine. By this means it provides an exhaust system in which the exhaust gas pulse frequencies can be varied over the entire operating range of the engine to obtain desirable pulse frequencies matching the cylinder exhaust timing for efficient extraction of the exhaust gases,improvement in volumetric efficiency and a higher maximum engine speed. The various methods can be controlled by sensors connected to any or all of the  engine rpm sensor, the gear change mechanism and the throttle valve.          The methods are suitable for any typo of multi-cylinder internal combustion engine,  that is,  in-line cylinders, horizontally opposed cylinders, V cylinder arrangement etc. and for any type of application whether stationary or on a moving vehicle. The methods solve the problem of other methods related to positioning on a motor cycle by being able to have the exhaust pipe combination change valve located between the engine  cylinder  exhaust  outlet  and later junctions of the exhaust pipes.  Also the layout of the system is such that the components can be simply protected from damage and easily accessed for maintenance.

Abstract: ABSTRACT OF THE DISCLOSURE    A parallel asynchronous elasticity buffer.  Selection of the address of a storage element for writing or reading of data is provided by asynchronous input and output pointers imple-mented using circular gray code counters.  The buffer is ini-tialized once during transmission of each frame of data so that the pointers do not select the same storage element for writing and reading at the same time.  Write overflow or read underrun of a storage element is detected before any data corruption can occur by comparing the input and output pointers.  An error con-dition is detected if the input and output pointers overlap for a threshold period, which can be shorter than the period re-quired for writing or reading of a multibit data unit to or from the buffer.  The overlap time period is determined by comparing the pointers at one or more sampling times corresponding to se-lected phases of a clock signal.
