Title: Air cylinder
Inventor: LABAIR RICHARD L
IPC: F15B15/14
Filed: 1987-04-15
Granted: 1991-08-27
Abstract: AIR CYLINDER               ABSTRACT OF THE DISCLOSURE         A fixture cylinder is provided that permits the use of integrally mounted proximity switches with the same fixed probe lengths on both end caps without requiring the use of spacers.   The cylinder includes a body in which a piston assembly is slideably mounted about a longitudinal piston axis in a bore in the body.  The piston assembly has a piston head, piston rod and a pair of hubs of equal diameter on opposite sides  of the piston head.   First and second end caps are provided on opposite ends of the body.  Each end cap has a plurality of outer edges and a generally flat mounting surface is provided on one edge thereof for receiving a proximity switch.  An aperture perpendicularly extends through each end cap and communicates with the bore in the body of the piston assembly.   Two  substantially  identical  proximity  switches having generally flat mounting surfaces and the same fixed probe  lengths  are  employed.   The  proximity  switches  are secured to the  end  caps  so  that  the  respective  mounting surfaces  abut  and precisely define the  distance that  the probes extend towards the piston hubs in the bore.

Granted: 1992-03-24
Abstract: Abstract of the disclosure Process for the sulfation of partial esters of aliphatic polyhydric alcohols A process for the sulfation of primary free OH groups of partial esters of aliphatic polyhydric alcohols with SO3 is described.  As solvent, use is made of at least one compound which has a boiling point of 40 to 200°C at a pressure of 98 kPa, is liquid under the chosen reaction conditions and, in addition to at least one trivalent nit-rogen atom, which is linked exclusively to carbon atoms, contains only carbon, hydrogen and optionally ether oxygen atoms.  The sulfated partial esters and also their alkali or alkaline earth salts are obtained with a good color and good yield and without the formation of large quanti-ties of salts which pollute the waste water.  They may be used, for example, for detergent base materials, synthetic soaps and flotation agents.

Title: Packer bypass
Inventor: CHRISTENSEN JON B
IPC: E21B33/124
Filed: 1987-12-03
Granted: 1991-05-14
Abstract: Abstract A packer bypass for use between a pump and packer in a testing string for venting said pump and packer to a well annulus after completion of a testing operation.  The packer bypass comprises a case with an inner flow tube disposed therein such that an annular passageway is defined therebe-tween.  A piston having a lower portion is reciprocably disposed in the annular passageway.  A plurality of latching fingers are pivotally mounted to the lower end of the piston and biased towards a latching position.  A bypassing mandrel is reciprocably disposed in the annular passageway below the piston and has an open position for bypassing pump pressure thereabove and packer pressure therebelow to the well annu-lus and also has a closed position in which bypassing is prevented.  The mandrel may be raised from the closed posi-tion to the open position by lowering the piston and engaging the latching fingers with a flange on the mandrel.          When the mandrel is moved to the open position, the latching fingers are automatically released.  The mandrel may be pumped back to the closed position for another test.          Hydraulic pressure across the mandrel prevents overpull, and pressure balancing on the piston prevents undesired downward force on the packer.

Abstract: A Method And An Apparatus For Determining Surface Shape Utilizing Object Self-Shadowing Abstract A method and apparatus are provided wherein a moving light source is passed over a surface whose shape is to be determined, in two orthogonal paths and is fixed at a plurality of positions along each path such that the light source illuminates the surface at a different slope for each posi-tion.  A binary image camera photographs the surface for each of the fixed positions and the point at which each of a plurality of points on the surface is first illuminated and last illuminated, as well as the points that last shadowed or last failed to shadow any given point, are recorded.  Constraint equations develop the effect a given point has on its last and failing shadowers and the effect each last and failing shadower has on the given point.  Upper and lower bounds of these points are iteratively re-calculated according to the constraint equations until none of the points exhibit any more change in their upper and lower bounds.

Abstract: ABSTRACT OF THE DISCLOSURE    A method of deriving the word timing or word boundaries of a PPM signal, without requiring a synchronizing marker to be added to the PPM signal, employs a bipolar evaluation signal which begins at any time slot of the PPM signal.  The evaluation signal is multiplied repeatedly with successive portions of the PPM signal within a time frame of the PPM signal which extends over a plurality of word lengths, and the product signals are integrated.  Such repeated multi-plications with subsequent integration are performed a number of times, with the evaluation signal being offset by one time slot each time.  The time position of the evaluation signal which, after repeated multiplication and integration, produces the smallest possible signal, is considered to be in phase synchronism with the word timing of the PPM signal.
