Granted: 1990-11-27
Abstract: A B S T R A C T IMPROVEMENTS IN OR RELATING TO BEAT-SHRINKABLE            TUBULAR FILM MATERIAL           In the manufacture and use of tubular casing material, a starting material having heat-shrinkable properties is partially shrunk to a controlled reduced calibre and then is further shrunk during use.          The shrinking may either take place during use, for example by partially shrinking tubular film material over a stuffing horn 2 in a shrinker 6 (Figure 1) or may be carried out during manufacture by partially shrinking a length of tubular film material to a controlled reduced calibre before sale (Figures 2 and 3).

Inventor: FURMANEK ROBERT A
IPC: B23Q1/26
Filed: 1987-10-30
Granted: 1991-04-16
Abstract: Abstract Slide and Way Assembly and Method of Making Same A slide (20) having conveniently removable and replaceable bearing components (28-38) with the bearing components engaging seats (50) made of resilient, low friction material.  The slide is supported on ways (24,  26) by way bearing pads (28-32) and opposed adjustable bearing  assemblies  (34-38).   The  seats  (50)  are formed by rough machining pockets (40,  42)  into slide (20), positioning the slide (20) onto the ways (24, 26), positioning tooling blocks (60) at the locations normally occupied by the bearing components (28-36), and filling the spaces between the tooling blocks and pockets with a low friction, epoxy material, thereby forming the seats (50).  Any one of the bearing components (28-38) may be removed and replaced without removing  the slide  (20)  from the ways  (24,  26).   Further,  each bearing assembly (34, 38) is mounted on one side of a respective way with a way bearing pad (28-32) being mounted on the opposite side of the  way.   Moreover,  each  bearing  assembly  (34-38)  includes  an adjustable tapered gib (54) that is sandwiched between a seat (50) and a bearing pack (56) that engages a way (24 or 26).

Title: Amphiphilic phase behavior separation of carboxylic acids/hydrocarbon mixtures in recovery of oil from tar sands or the like
Inventor: BABCOCK ROBERT E
IPC: C10G1/04
Filed: 1987-11-06
Granted: 1991-09-03
Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed a process of oil recovery from tar sands or separation of hydrocarbons from a solid or viscous bitumen source wherein carboxylic acids or carboxylic acid mixtures are utilized as a solvent or diluent and are mixed with heavy crude oil, injected into an oil reservoir or mixed with tar sands in a surface vessel to reduce the viscosity of the crude oil and to increase the mobility of the oil. The process is characterized by the use of an amphiphilic phase separation induced by injection of isopropanol or other alcohol to facilitate the recovery of carboxylic acid diluent from the bitumen product, and another phase separation step may be employed to separate the carboxylic acid component from the alcohol. Sodium chloride or other brine solution is usually mixed with the alcohol and many embodiments combine a light hydro-carbon such as heptane with the carboxylic acid as an additional solvent. Carboxylic acids in the form of fatty acids with from 8 to 20 carbon atoms are preferred. Distillation may be employed to separate the alcohol from the brine solution or to concentrate the alcohol for recycling. All the processing chemicals may be recycled in the process with the exception of the light hydrocarbons, which may or may not be separated from the product stream in later conventional processing.

Title: Method and system for determining curvature in fluid transmission pipelines
Inventor: LARA PEDRO F
IPC: E21B47/02
Filed: 1987-12-23
Granted: 1991-05-28
Abstract: ABSTRACT OF THE DISCLOSURE        A change in curvature or displacement of a section of submarine  or subterranean fluid transmission pipeline is measured by traversing the pipeline with a pig having an onboard  instrument  package,  including  accelerometers and a longitudinal position measuring device comprising a magnetometer for counting the girth welds or other known magnetic anomalies  along the  section  of pipeline to be measured.  The accelerometers are mounted at the central longitudinal axis of the pig which is substantially coinci-dent with the central longitudinal axis of the section of pipeline being measured so that the roll attitude of the pig does not influence the signals generated by the accel-erometers.  This arrangement precludes the requirement of mounting the  accelerometers  on  a  gyroscopic  stabilized platform since the absolute position of the pig in space is not required, but primarily the change in curvature or displacement of the pipeline from a predetermined course is what is desired to be known.  The pig weight is mini-mized and supporting structure  is sufficiently stiff  as to provide natural modes of vibration at frequencies higher than the frequencies of  signals of  interest as the pig traverses the pipe.

Abstract: SCORED FIBERBOARD HAVING IMPROVED MOLDABILITY                ABSTRACT OF THE DISCLOSURE         A plurality of intermittent incisions are made in a surface region of a fiberboard to sever fibers without removing them from the surface region.  The resultant fiberboard may be molded under heat and pressure to a three dimensional hardboard with high fidelity to the mold and without causing stretch marks, tears or fractures.  The fiberboard may be a dry consolidated mass of wet-felted cellulosic fibers.  The invention is particularly valuable in the molding of boards made from redwood fibers and other long fibers. The intermittent incisions may be made along one or more lines  parallel  to  or  perpendicular  to  the longitudinal edge of the fiberboard but a grid of incisions along intersecting lines is advantageous.  To cut the incisions, the fiberboard is preferably moved on a conveyor belt while an assembly of toothed cutting disks is rotated in cutting engagement with the board. The cutting disks are mounted co-axially on a motor-driven shaft.
