Granted: 1991-09-24
Abstract: ABSTRACT     A water purification arrangement which uses as the water treating  agent  ionized  oxygen  allotrope  gas  in  multiple (multivalent) ion charge forms (as distinguished from common chemical treatment substances), in which the raw material for practicing  the  invention  is  ambient  atmospheric  air,  and specifically its atmospheric oxygen content.  The arrangement provided has a gas flow path having multivalent oxygen ion allotrope forming sites that each include a magnetic flux field energy zone within the ambient air flow path characterized by interacting   multipolar   magnets   that   have   a   central demagnetization aperture and that exert flux fields across the flow path, and one or more elongate oxygen photolysis lamps enveloping  the  flux  with  ultra-violet  light  wave  length ionizing electron-volt radiant energy emissions.  The ambient atmospheric air is passed in a continuous flow through the flow path and then is conveyed to and is interspersed in the water to be treated in a continuous flow application.

Title: Box parts
Inventor: LEEPER ALAN L
IPC: B31B3/52
Filed: 1987-03-27
Granted: 1990-03-27
Abstract: ABSTRACT A machine to form an end of a unit of a box from a flat box blank that incudes two sides, a bottom, and, at each end, an end flap supporting a cantilevered sealing tab, and two side tabs supported by the two sides. A planar folding table receives the end flap and the sealing tab. A pair of side guides secures the two sides of the box blank and guide the box blank in its rearward travel. An end flap folding mechanism serves to fold the two side tabs attached to the box sides inward through ninety degrees to a position essentially parallel to the fold line. An adhesive applicator applies an adhesive ribbon in a predetermined pattern to the sealing tab and, sometimes, to the end flap. A drive mechanism folds the folding table from a position in which the plane of the folding table is in the plane of the movable table to a position in which the plane of the folding table is perpendicular to the plane of the movable table to fold the end flap through ninety degrees. A finger assembly consisting of a plurality of press fingers is disposed above and separated from the movable table. The press fingers have a planar bottom face and a planar back. The press fingers operate in pairs and are movable transversely to a position where the fingers of a pair are spaced from one another to another position wherein the press fingers of a pair are in close proximity to one another. Some of the finger assembly can be moved selectively transversely to accommodate various box widths.

Title: Method and apparatus for investigating drag and torque loss in the drilling process
Inventor: SHEPPARD MICHAEL C
IPC: E21B44/00
Filed: 1987-10-05
Granted: 1993-01-05
Abstract: ABSTRACT     Drilling conditions are analyzed by, for example, measuring the tongue applied at the surface to the drill string and the effective torque acting on the drill bit.  The applied torque and effective torque are compared to determine torque loss,   Likewise,  applied weight on the drill string and effective weight acting on the drill bit may he measured and compared to determine drag losses.  These measurements and comparisons may be done in real-time to diagnose unfavorable drilling conditions.  The torque or weight measurements may be used to calculate a variable coefficient of  friction acting on the drilling string.  Trends  in the torque or weight  losses,  or  in  the  value  of  the  coefficient  of friction, may be observed on a plot of these quantities as a function of depth.

Granted: 1993-09-14
Abstract: APPARATUS AND METHOD FOR PARTICLE ANALYSIS           Abstract of the Disclosure Apparatus for analyzing particles contained in a fluent medium (12). The apparatus includes a body (20) having a window (30), an optical source preferably comprising a laser diode (100) having a small light emitting area (140), and an optical system (102) for focusing the light from the laser diode at a focal spot (84) such that the size of the focal spot is approximately equal to the size of the light emitting area of the laser diode. A photodetector (106) is mounted in the body and detects light backscattered from the focal spot by particles in the fluent medium, and produces an electrical signal that comprises a series of pulses associated with the particles. The electrical signal is input to a detector thatcounts the pulses and indicates the number of particles in the fluent medium. The detector includes discrimination means for preventing the counting of a pulse that has a rise or fall time above a predetermined threshold, thereby discriminating against particles that are not at the focal spot. Means are provided for measuring the integrated amplitude of the electrical signal, and for varying the distance between the focal spot and the window to maximize such integrated amplitude. An intrinsically safe embodiment is also disclosed in which the probe positioned at the measuring site does not include any electrical components. This embodiment may be implemented using light of multiple wavelengths for characterizing individual particles.

Abstract: ABSTRACT         A method of treating substrate surfaces with the aid of a plasma is described.  The substrate is supported in a treatment-chamber to which a plasma is passed via a plasma-inlet from a plasma-generator.  A reactant is introduced into the plasma-generator and the pressure of the treatment-chamber is maintained lower than that of the plasma-generator.  A flushing gas is passed into the plasma-generator upstream of the cathode in the generator and the reactant is fed downstream of the cathode after the flushing gas has passed the cathode.  The flushing gas prevents contamination of the plasma by the cathode.

Title: Three-dimensional double air gap high speed solenoid
Inventor: MOHLER DAVID B
IPC: H01F7/08
Filed: 1988-06-22
Granted: 1993-01-19
Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed is a solenoid having a central and a peripheral air gap between the armature and the pole piece. The energizating coil is located in the space between the central core and the peripheral portions of the pole piece and armature.  In one embodiment, an output shaft is received in an aperture in the central core of the pole piece and connected to the armature.  In preferred embodiments, a longitudinally and radially extending slot is provide to produced eddy current losses.  Additionally, mass is removed from non-critical portions of the armature to reduce its weight and increase its acceleration during energization of the solenoid.  By utilizing stepped changes in the pole piece and armatures, peripheral portions and central core portions as well as variations in the central and peripheral gaps, the force/distance curve of the solenoid can be tailored to the specific application.  In one embodiment, the armature comprises a central core which is moveable relative to the peripheral portion only in the operating direction.  This permits a very small peripheral gap to generate high initial acceleration forces which are imparted to the armature central core but does not limit the central core to an inordinately short operating stroke.
