Abstract: An apparatus which utilizes precut, coated fiber canvases, vertical and horizontal support elements, multiple rotatable couplings and detachable shoe-like receptacles, together with lacing rope and other miscellaneous hardware, to provide a shelter for a boat secured in a floating dock. The modular structure and unique design of the apparatus permits it to be easily and quickly erected or dismantled, on site, using only a set of Allen Wrenches. Each of the partially preassembled vertical support elements is unfolded and reenforced on the site with a lateral support member and a pair of angular truss members. Multiple numbers of these vertical support elements are then interconnected by three precut horizontal truss members and two precut horizontal roof support members to produce whatever length of dock cover is required.

Abstract: A carbon composite article and the method of making the article wherein selected carbon fibrous materials are formed into a basic starting substrate having a volume greater than the desired volume of the finished article. Very small amounts of a carbonaceous binder material are used to bond the fibrous materials together at a multiplicity of bonding sites. The basic substrate is then subjected to controlled temperatures and pressures to form a shaped substrate characterized by having a high degree of open porosity, a predetermined shape and structural integrity sufficient to withstand subsequent substrate processing. The carbonaceous binder is applied to the fibrous material in a manner whereby substantial encapsulation of the individual fibers is avoided so that the portions of the fibers disposed intermediate the bonding sites are free to move to accommodate and effectively distribute stresses which may be generated within the substrate due to material shrinkage or other process related causes.

Abstract: Oil is recovered from a coastal or offshore reservoir by a water injection process in which a dispersing agent is added to sea water which is then filtered. The treated sea water is then injected into a reservoir through an injection well and crude oil is recovered from a production well.

Abstract: A loudspeaker enclosure for housing a basic speaker and providing a conduit for channeling the sound waves emitted from the back surface of the basic speaker so that the sound waves are shifted in phase and emerge from a port in the enclosure and add to, rather than acoustically cancel, the sound waves emitted from the front surface of the basic speaker. The sound waves from the back surface of the speaker travel through the length of the conduit which is folded through several 45.degree. angles upon itself. These sound waves are directed through the conduit by striking and reflecting from a plurality of at least six reflector panels which are mounted at 45.degree. angles. In this manner, due to the nature of reflections at 45.degree. angles, each portion of a sound wave impulse travels the same distance as each other portion and the impulse emerges from the port basically intact. The enclosure has a unique shape because of the several foldings of the conduit through 45.degree. angles.

Abstract: A photographic print processing system comprising a processing basket assembly and a tank unit. The basket assembly includes a basket frame structure, a pair of movable top combs, and a plurality of pairs of removable guide members. The basket frame structure comprises front and back members with handles, side combs, bottom combs and base plates. The removable guide members are positioned within the basket and facilitate inserting each of a plurality of exposed photographic sheets of material into the basket with the lights off. As the exposed sheets are placed within the basket, the guide members are withdrawn. Each basket front and back member has a raised guide portion for use in positioning the top combs so that each photographic sheet is secured on all sides within the basket frame. The basket frame further comprises a plurality of spaced apart base plates which induce fluid turbulence and control fluid direction during mild vertical agitation of the basket within the tank.

Abstract: Sea water for injection into an oil field to maintain the pressure thereof is filtered through a filter element composed of polyester fibres. The diameter of the fibres is from 8 to 15 microns, the thickness of the element at least 7 mms and the density in the range 0.08 to 0.1 gm/cc.

Abstract: A color filter head for attachment to photographic enlargers has a universal mount adapted for ready attachment to lens mounts regardless of size and a unique system for sequential color addition and integration to produce a color corrected print. The filter head includes a manually rotatable, adjustable filter disc assembly having high-density filter segments which are relatively movable under an overlying cover disc having two opposed open quadrants. The filter assembly acts like a balanced fly wheel which is mounted beneath the enlarger lens. In normal use, the light from the lens passes through the open quadrants of the cover disc and through the portion of the filter material disposed in the open quadrants as the wheel is manually rotated during the printing step. The system thereby utilizes a method of sequential light addition and integration. Sequential periods of white and colored light are integrated to produce the desired total exposure.

Abstract: A display frame construction employs spaced end plates having at least two contiguous curved edges to receive at least two webs or sheets carrying graphic displays. Interposed slotted spacer members which interfit with and maintain the plates in spaced generally parallel relation may be employed to receive the contiguous edges of the displays. Edge portions of the plates are also slotted along the curved edges whereby two opposed edges of a rectangular picture or other display web may be received in plate slots which follow the edge contours of the plates and the other pair of opposed edges of the display may be received in the slots of the spacer means. The plates and spacers may interlock or resilient means between the plates may be employed to maintain the frame components in a state of assembly.

Abstract: The transverse properties of high modulus fabric such as graphite are significantly improved by continuously processing the material through a multiple roller unit under warp tension while restraining fill shrinkage by wrapping the material no less than 180.degree. around each roll and by minimizing unrestrained inter-roll travel by controlling the inter-roll span. Graphite precursor fabrics such as polyacrylonitrile (PAN) can be stretched as high as 45% in the warp direction with as little as 1-2% shrinkage in the fill direction. The invention also relates to simultaneous stretching and preoxidation of the precursor fabric under tension and while minimizing fill shrinkage.

Abstract: The present invention is an optical aid especially applicative as a focuser for use with photographic enlargers. The structure of the device makes it possible to focus at any point on the projected image at the easel surface. The focuser can be hand held by the operator with one reference point placed on the easel surface in an area where the image is to be focused. The focuser has a mirror which reflects the light of the enlarging apparatus onto an integral viewing surface with the distance from the reference point to the center of the mirror along a reference axis being precisely the same as the distance from the center of the mirror to the center of the viewing surface along a viewing surface axis. The angle of the viewing axis relative to the mirror surface must be the same as the angle of the reference axis to the mirror surface.
