Abstract: ABSTRACT      A method is provided for producing a butter-like composition which has a taste, texture and mouth feel similar to butter but which is spreadable at refrigera-tion temperatures. A feed of at least one liquid dairy product which is primarily an oil-in-water emulsion and has a fat content of at about 8% is prepared. The feed is concentrated by removing water until a concentrate having at least about 40% fat is obtained. The concen-trate is homogenized and a phase reversal of the con-centrate is caused,  either prior to,  during or after homogenization, so that the emulsion of the concentrate is converted from a primarily oil-in-water emulsion to a predominantly water-in-oil emulsion. The concentrate, thereby, forms a butter-like composition, and the ratio of oil-in-water emulsion to water-in-oil  emulsion in the composition is at least about 6:4, and preferably between 7:3 and 8:2.

IPC: E21B47/06
Filed: 1988-06-16
Granted: 1991-09-24
Abstract: Abstract A perforate,  test and sample tool for obtaining fluid samples  from a formation reservoir  in a well.   The tool comprises  a  retrievable  packer,  perforating  guns  and  a sampler  disposed  between  the  packer  and  guns  which  is adapted for entrapping a fluid sample without flowing well fluids into the tool string.   An operating piston is sli-dably disposed in a cylinder above the packer and is used to actuate a sampler valve in the sampler.  A seal insures that all  portions  of  a  sampling  chamber  in  the  sampler  are disposed below the packer.  In one embodiment, the operating piston is actuated in response to a pressure differential between a well annulus  above  the packer and an internal pressure in the tool.   The sampler includes a plurality of sampler modules disposed in the sampling chamber.  Each of the  sampler modules  includes  a valve which automatically closes after a predetermined volume of fluid fills a sampler module  chamber  defined  in  the  sampler  module.    Testing gauges may be disposed in the sampler adjacent the sampler modules.  A shear pin holds the operating piston and sampler valve in a first closed position as the tool in run into the hole,  and  a  locking  dog  assembly is  used  to  lock  the operating piston and sampler valve in a second closed posi-tion after the sampling chamber has been filled.  A method of using the perforate, test and sample tool is also disclosed.

Title: Printing of angled and curved lines using thermal dot matrix printer
Inventor: BROOKS RALF M
IPC: G06K15/02
Filed: 1988-07-15
Granted: 1992-02-18
Abstract: PRINTING OF ANGLED AND CURVED LINES USING THERMAL DOT MATRIX PRINTER            Abstract A method and apparatus are described for enhancing the visual quality of dot matrix characters printed by means of thermal printing technologies, particularly in enhancing diagonal lines and blended radii of curvature.  Two independent techniques can be combined or used in isolation to effect this print enhancement.  The first, quarter dot step resolution, enables printed dots to be positioned at one quarter their previous step displacement distance.  Memory must be expanded to handle increased dot position resolution.  The second technique is element energy control, which enables each element in the printhead to emit different energy levels.  The individual dot energy control translates into control of the printed dot shape and size, which when properly controlled, allows printing of diagonal lines and blended radii of curvature.  This second technique further increases the required memory space by an additional factor.

Title: Fiber optic bore inspection probe
Inventor: FRANKLIN JOSEPH O JR
IPC: G02B6/06
Filed: 1988-11-10
Granted: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE      A bore inspection probe utilizing optical fibers is disclosed.  A first layer of optical fibers and a second layer of optical fibers are placed over a tubular mandrel having a circular cross-section, and a mirror is placed adjacent the distal ends of the first and second optical fiber layers within the probe.  The proximate ends of the optical fibers forming the second optical fiber layer are gathered into a bundle for exposure to a light source, whereas the proximate ends of the optical fibers forming the first optical fiber layer are fanned outwardly adjacent the end of the probe to form a thin optical fiber line.  Light is transmitted to the surface of the bore via the second optical fiber layer and the mirror and is reflected from same via the mirror and the first optical fiber layer to form an image on the thin optical fiber line.  Synchronization of a film with the movement of the probe within the bore produces a panoramic image of the surface of the bore on the thin optical fiber line.

Title: Radio communications device incorporating channel guard decode and priority channel scanning

Granted: 1994-01-25
Abstract: RADIO COMMUNICATIONS DEVICE INCORPORATING    CHANNELS GUARD DECODE AND PRIORITY         CHANNEL SCANNING           ABSTRACT OF THE DISCLOSURE    A significantly improved scanning method and apparatus is disclosed which allows tone channel guard decode and scan to optimally coexist on the priority channel.  In an exemplary embodiment of the present invention, tone channel guard decoding processing is divided into three processing windows.  The first window (hereinafter referred to as SHORTLOOK) serves to indicate whether channel guard might be present.  If the SHORTLOOK window processing indicates that the correct channel guard might be present, then a further processing window, hereinafter referred to as SECONDLOOK is initiated.  If at anytime during the SECONDLOOK time period, a second predetermined threshold is exceeded, the system is informed that the correct channel guard tone pattern is most probably present.  The audio is them unmuted, even though the SECONDLOOK time period expires before the channel guard tone pattern is capable of being reliably detected in accordance with conventional standards.  A LASTLOOK window is utilized when the SECONDLOOK window has detected a tone and opens the audio.  During the LASTLOOK window, a further tone channel guard detect threshold is monitored.  If this threshold is exceeded, then the priority channel audio is allowed to remain active, thereby serving as a check on the determinations made in the SHORTLOOK and SECONDLOOK windows.
