Title: Low pressure relief valve
Inventor: GAUSMAN THEODORE J
IPC: F16K17/04
Filed: 1988-08-26
Granted: 1992-05-19
Abstract: LOW PRESSURE RELIEF VALVE Abstract of the Disclosure A relief valve for low pressure operation includes a valve body having an enlarged cylindrical bore in alignment with an inlet port and defining a valve chamber.  An outlet opens laterally from the valve chamber at a location spaced from the inlet port.  An insert member is received in the bore and defines an axially facing raised seat circumferentially about the inlet port at a location closely adjacent the outlet port.  A poppet valve with a truncated conical configuration and a maximum outer diameter only slightly less than the inner diameter of the enlarged bore is mounted for engaging the seat and blocking flow through the inlet.  A biased stem extends into the valve chamber in axial alignment with the seat insert.  The stem has a cylindrical end portion which is received in a cylindrical opening formed axially into the poppet valve on the end thereof opposite the seat insert.  The cylindrical end portion and the cylindrical opening are sized to permit lateral shifting and alignment of the poppet valve relative the seat while preventing excessive and unwanted tilting of the poppet valve relative to the bore.

Abstract: Abstract of the Disclosure Means for lifting formation fluid to the surface in a drill stem test.   The drill string has  first openings allowing entry of formation fluid and upwardly spaced second openings which are normally closed by a sleeve slidably mounted on the drill string.  Fluid pressure from within the drill string impinges on a transverse surface of the sleeve and forces it down, allowing treatment fluid to enter the drill string from the annulus between the drill string and the well bore.  A jet pump comprised of a flow constriction creating  a  venturi  effect  causes  treatment  fluid  to accelerate upwardly in the drill string, the circulation of the treatment fluid drawing the formation fluid to the surface.  The second openings covered by the sleeve include the fluid crossover of the jet pump.  A standing valve in the drill string between the first and second openings allows down hole shut-in and pressure build-up tests.

Title: Opener assembly with depth gauging from a press wheel
Inventor: NEUMEYER LOWELL H
IPC: A01C5/06
Filed: 1988-10-07
Granted: 1991-03-26
Abstract: OPENER ASSEMBLY WITH DEPTH GAUGING FROM A PRESS WHEEL              Abstract of the Disclosure Relatively simple opener assembly structure for maintaining a generally constant vertical relationship between an opener and a trailing press wheel.  The structure provides benefits of a parallel linkage design but obviates the extra links of, and provides better trash shedding and tripping characteristics than, a parallel linkage design.  An opener arm and a press wheel arm are pivotally connected to a leg assembly for rocking about offset pivotal axes.  As the press wheel arm oscillates over uneven ground, the opener arm is constrained for vertical movement with the central portion of a press wheel arm by a track and follower assembly.  The opener arm is substantially shorter than the press wheel arm and causes the opener to rotate both rearwardly and upwardly upon encountering trash or other obstacles.

Title: Silicone polymer encapsulated substrates
Inventor: CALDWELL JAMES MICHAEL
IPC: D06M15/643
Filed: 1989-03-14
Granted: 1999-11-02
Abstract: A flexible porous substrate (i.e., leather, paper, and open-celled foamed structures) comprising a matrix having open cells therein is provided wherein the cells are partially lined with a silicone polymer. Most cells remain open, but are partially filled with silicone polymer. The substrate displays characteristics not achievable in prior art substrates treated with either fluorochemical or silicone polymer, such as higher water droplet contact angle, higher abrasion resistance, and higher water rewashability, yet breathability and water repellency remain excellent.      The treated substrate can display hand characteristics similar to the hand of the untreated substrate.      Optionally but preferably, the substrate is preliminarily uniformly impregnated with a fluorochemical. Also optionally, the substrate can be post treated with fluorochemical to improve characteristics, such as oil penetration and soil resistance. The substrate is produced by using a pressure impregnation technique upon a substrate using a curable silicone polymer composition.

Abstract: ABSTRACT                        Braided Sleeve A braided sleeve is formed from a tow of flexible filaments such as glass fibers and a rigid filament such as a stainless steel wire.  The rigid filament reduces the tendency of a braided sleeve to fray at its ends, and can cause the end portions of the sleeve to taper inwardly, which can enhance the thermal insulation properties of the sleeve.  The sleeve may be coated with polymeric material.

Abstract: ABSTRACT OF THE DISCLOSURE          Method of fabricating a coherently exposed multiple holographic lens including a first step of fabricating an incoherently exposed master multiple holographic lens with an array of overlapping holographic lens elements, each of said lens elements having an interference pattern substantially covering the entire area of the lens.  The master multiple holographic lens is illuminated with a first beam of light from a coherent source to provide a plurality of light waves equal in number to the number of lens elements in the master lens.  The plurality of light waves overlap in a region downstream of the master lens.  A holographic recording medium is positioned in the region of overlap such that an area thereon is illuminated simultaneously by each of the plurality of light waves.  A second beam of light from a coherent source is directed toward the area of the holographic recording medium illuminated by the plurality of light waves.  The holographic recording medium is exposed simultaneously to the second beam of light and the plurality of light waves and is developed to form a coherently exposed multiple holographic lens.  A larger area of overlap of the plurality of light waves illuminating to recording medium is provided by an imaging lens positioned to capture and redirect the waves.  A one to one image of the master lens can be recorded by positioning a pair of imaging lenses between the master lens and the recording medium.

Abstract: The components (1,2,3) of the construction are formed by two rigid surface layers (6,7) between which are unbroken insulating layers (8). The male type edge parts (4) are formed by the unbroken insulating layer (8) and the two rigid surface layers. Each of the surface layers comprises a landing or ledge (9) on the surfaces (10,11) turned away from the insulating layer in the transition between the male type edge parts (4) and the remaining parts of the construction. The female type edge parts (5) are formed by only the two rigid surface layers, which are adjusted so that they connect against the landings or ledge formations. Their surfaces turned away from the insulating layer form level surfaces in the transitions between adjoining components. The insulating layers connect directly with each other so that an unbroken insulation system exists throughout the construction.

Abstract: The process consists in successively separating increasingly heavy petroleum cuts at the head of a plurality of columns CO1, CO2, CO3 and Cl0 of a first series of columns which feed individually each column of the second series. The column CO7 is a gasoline stabilizing column which feeds an installation for fractionating light petroleum gases. The column CO4 is a gasoline fractionating column. The columns CO5 and CO6 are columns for separating petroleum naphthas from kerosine. The atmospheric residue collected at the bottom of the column Cl0 is processed in the vacuum distillation column Cl2 and the residue from this column is processed in the second vacuum distillation column Cl3 after reheating in a furnace. By carrying out a succession of progressive separations performed in a series of columns of small volume, more efficient utilization of the recovery heat is achieved.
