Abstract: A method for forming concrete retaining wall blocks from a single mold with selectable dimensions such that a retaining wall of a desired setback can be defined.  One of a plurality of core bars is implemented with the mold during the manufacturing process to define a laterally extending recess of a same width across the lower major surface of a composite block.  Subsequently, the composite block is split along a midsection thereof to form a pair of identical blocks, each block having a laterally extending front lip and a laterally extending lower recess.   The depth  of  the recess  corresponds  to  the  setback of  a retaining wall formed therefrom.  The shallower the lower recess,  the greater the setback of the retaining wall formed therefrom.  Further, the present method facilitates creating a pair of blocks with a textured front surface to provide  an  aesthetically  pleasant  retaining  wall.  A plurality of core bars are available with different widths, and are used to form retaining wall blocks adapted to define retaining walls with setbacks from 0° to 12°.  The core bars can have a rectangular or trapezoidal cross section.    Each  formed  retaining  wall  block  has  core openings to reduce the weight thereof.

Abstract: Isocyanate prepolymers which are useful as binders are made from a polyisocyanate mixture and a hydroxyl compound having at least about 1 hydroxyl group. The polyisocyanate mixture is made up of from about 50 to about 60% by weight of polyphenyl polymethylene polyisocyanate and from about 40 to about 50% by weight of an isomeric mixture of diphenylmethane diisocyanate (MDI). The isomeric mixture of MDI is made up of from about 4 to about 30% by weight of the 2,4'-isomer and from about 70 to about 96% by weight of the 4,4'-isomer. The binders of the present invention are advantageous in that they may be used in high moisture, low temperature conditions without a catalyst. Reduced MDI emissions are also achieved when the binders of the present invention are used to make composite materials.

Title: Traveling mat backing
Inventor: ERLAND JONATHAN
IPC: H04N9/75
Filed: 1996-10-10
Granted: 2002-11-26
Abstract: The present invention provides an improved backing screen having particular application for use in composite photography. In particular, the present invention relates to color difference composite photography, whether still, motion picture, video, solid state digital electronic or electrophotographic imaging, in which foreground and background scenes are separately recorded and subsequently combined using known "blue screen" or special color background techniques to form a single image. The present invention includes a biaxially stretchable fabric of synthetic fibers treated with a dye formulation, including fluorescence which is reactive to the visible spectrum, to achieve any of a variety of specific spectral loci and luminances, for the purpose of providing a precise chromatic actinic stimulus response for a silver halide photographic film, or similar response for electronic imaging devices. The selected backing is deployed in a support such that the fabric is stretched to a smooth, featureless surface and then illuminated. Foreground subject matter interposed between the camera and the backing or directly on the backing will therefore be readily distinguished and "matted" for compositing by methods well known to the art. In a further aspect of the present invention, the light emitting characteristics of the fluorescent matte fabric of the present invention may be advantageously relied upon to obtain the desired lighting effect in, for example, underwater photography. In yet another embodiment of the present invention, the matte fabric of the present invention may be configured to cover objects or parts of a person in a field of view.

Abstract: Methods and apparatus for (a) increasing expansion tank "acceptance" (defined herein as working fluid storage capacity); and (b) adjusting the rate of pressure variations within a prespecified range in precharged fluid storage systems (for example, holding pressure down below a prespecified threshold value for a given volume of acceptance, stored water temperature level, etc.). A          "volatile" fluid (defined herein as a fluid having a boiling point within the predetermined pressure and temperature operating ranges for a given system), is used at least in part as the expansion fluid in an expansion tank included in a fluid storage system.  The volatile fluid, whether pure or combined with an ideal gas to temper the expansion fluids sensitivity to temperature, can be used to realize a relatively constant pressure "vapor spring" to make internal expansion tank pressure relatively independent of acceptance (where the term "relatively" in each instance is referring to a comparison between the use of an expansion fluid that contains a volatile liquid and one that does not contain such fluid).

Abstract: A compaction mechanism uses cables to move a compaction plate within a compaction chamber of a garbage truck. Cable guide pulleys are positioned adjacent a first end and a second end of the compaction chamber. Each cable has a first end and a second end, both of which are secured to the compaction plate.

Abstract: In contrast to typical machines though, the present invention discloses a device which allows the plate to "float" within the mechanism, so that any inaccuracies in dimensional tolerances between plate and knife are absorbed in a damping of the plate or bed of the mechanism. In this situation, the depth of the cut of the score line can be very reliably controlled, which results in the repeatable manufacturing of a child resistant, yet senior effective package. There is used a spring pre-load for this plate, which is such that cutting takes place yet, as the tool closes, the plate and package come in "metal to metal" contact, assuring "near perfect" cuts of the blister package. Extremely high tolerances are maintained, assuring packages which pass all levels and types of QA testing .
