Title: Treadmill exerciser
Inventor: POTTS LANNY L
IPC: A63B22/02
Filed: 1987-08-14
Granted: 1991-12-31
Abstract: TREADMILL EXERCISER     Abstract of the Disclosure A treadmill exerciser involving an upwardly and rearwardly sloping tread-mill having a plurality of steps which are activated by the weight of a person "walking" up them. The tread portion and the riser portion of each step are connected at both ends by hinges to each other and to endless chains which permit the steps to move or fold around end sprockets as the steps move from an upper inclined course of the chains to a lower inclined return course, and vice versa. A speed control mechanism, driven by one of the chains, employs a gyroscopic flywheel which cooperates with a non-rotatable but axially slidable brake drum to provide even, continuous step movement and a controlled start-up. The flywheel drives a plastic cylinder composed of plastic fingers which fly out, under centrifugal force, into contact with the inner surface of the brake drum thus preventing further increased speed for the user. With the brake drum in oneaxial position, the plastic fingers become partially disengaged allowing for rapid step speed; when the brake drum is moved to an opposite axial position, step movement is halted. The brake drum can be adjusted to positions between the above two axial positions to provide a controlled speed of movement compatible with the interests or needs of the operator. A control panel, mounted between the top of the tubular handrail shafts, provides operating, goal-setting, and health related information.

Title: Sequential hydraulic fracturing
Inventor: UHRI DUANE C
IPC: G09B25/02
Filed: 1987-08-27
Granted: 1991-03-12
Abstract: SEQUENTIAL HYDRAULIC FRACTURING      ABSTRACT   A process for sequential hydraulic fracturing of a hydrocarbon fluid-bearing formation.  A fracture is induced in the formation by hydraulically fracturing via one wellbore.  Thereafter, while the formation remains pressurized from the first induced-fracture operation, a second hydraulic fracturing operation is conducted via another wellbore substantially within the pressurized formation area of the first fracturing operation which causes a fracture trajectory to form contrary to the far-field in-situ stresses.  This second hydraulic fracture will tend to curve away from the first hydraulic fracture and has the potential of intersecting natural hydrocarbon fluid-bearing fractures in the formation.

Title: Reversible arming and firing mechanism for marine markers
Inventor: ST-ONGE MICHEL
IPC: F42C15/40
Filed: 1987-09-21
Granted: 1991-07-02
Abstract: ABSTRACT OF THE DISCLOSURE          An improved buoyant pyrotechnic marine marker of the type comprising a water impermeable jacket enclosing a pyro-technic candle, an ignition device for the candle consisting of a water actuable battery,  a candle igniting squib electrically acutated by the battery and  circuitry extending  between the battery and the squib.  The jacket has a gas emission hole for escape  of  the combustion gases  produced by the candle when ignited.   The  improvement  is  characterized  by  a  reversible arming mechanism comprising an open ended casing having walls, within which casing  is  seated  a  piston with walls  slidably cooperating with those of the casing, for axial movement of the piston with respect to the casing.  The casing and piston form a  chamber  adjacent  the pyrotechnic  candle  within  which  the battery is  seated.   Guides  are  provided  on  confronting overlapping portions of the walls of the casing and piston to permit the piston to slide between an unarmed position and an armed position.  An aperture is located in the walls so that it is closed when the piston is in unarmed position and open when the piston is in armed position.  The marker is provided with a switch   for  the  circuitry.  The  switch  is  mechanically associated with the piston and  the casing  so  that when the piston is in unarmed position the switch is in position keeping the circuitry open  and  when  the  piston  is  moved  to  armed position,  the switch automatically closes the circuitry.  The marker  according  to  the  present  invention  provides  easier arming and improved safety over conventional markers of this type.   It also provides the ability to dearm the marker,  if necessary,  and to repeat the arming procedure indefinitely as required.

Title: Rise-rate control of pulsed-bed granular medium filters
Inventor: GARZONETTI GARY A
IPC: B01D29/62
Filed: 1987-09-25
Granted: 1992-07-14
Abstract: RISE-RATE CONTROL OF PULSED-BED     GRANULAR MEDIUM FILTERS                         ABSTRACT           A method for controlling the pulsing of a granular medium filter, based on determination of the rise rate of liquid level above the filtration medium.   A pulse system is activated whereby sub-fluidizing pulses of a fluid are directed upwardly through the filter medium from an array of orifices, and each pulse is initiated whenever the determined rise rate attains a predetermined value.   The pulses dislodge solids from the upper surface of the bed and store a portion of the solids within the bed itself at particular loci, for decreasing the resistance of the bed and reducing the rise rate.  The frequency of backwash is optimized over a wide range of solids load, liquid load and other factors affecting the filtration.

Abstract: ABSTRACT           Drill cuttings contaminated with hydrocarbon, such as diesel oil,  kerosene or mineral oil,  from residual  drilling mud are cleaned up to a solid particulate form containing very low amounts of residual hydrocarbon by means of  an integrated  four-step treatment process.  In the first step, the cuttings are conditioned to destroy the complex fluid structure of the material and to break up agglomerations and clumps of  solid  particles  into  individual  particles. Preferably this is accomplished by addition of a compatible hydrocarbon diluent under shearing agitation. Secondly,  the destabilized contaminated cuttings are subjected to centrifugation to separate excess liquid. Thirdly,  the residual solids are treated,  preferably under shearing agitation, with water and an appropriate wetting agent at low concentration to displace residual surface hydrocarbon contamination.   Fourthly,  the treated cuttings  are subjected to a final phase separation step,  eg. by centrifugation of the total stream, or by screening and washing the coarse fraction followed by washing and filtration of the fines fraction.  The resultant solid material has a residual hydrocarbon content of less than about 6 grams per 100 grams of dry cuttings, largely in a form where it is unlikely to migrate out of the solids to harm the environment,  under normal environmentally experienced conditions.
