The patient positioning device of this invention relates to an apparatus used to assist a patient into a supine position and additionally through which traction is applied to the spine, such as physical therapy and chiropractic treatment. The patient positioning device is preferably a stand alone portable device that can be readily transported and adapted to almost any horizontal surface, such as a treatment table. A primary application of the leg support of this invention is in raising and supporting a patient's lower legs during before, during, and after traction is applied to a patient. The device includes a lower support frame, vertical supports, and a leg support coupled to a top frame. The patient positioning device may also have a motor which powers the leg support to rotate from a lowered position, in which a patient's lower legs rest on the leg support, to an elevated position in which a patient's lower legs are elevated. Once in the elevated position, traction can be applied to the lower back preferably with a cable and a board that is placed across the front of a patient's thighs.

High-quality composite printing elements are prepared without the need for precise registration of constituent photocurable elements by disposing at least one photocurable element, and preferably a plurality of photocurable elements, upon a surface of a printing element in approximate register and then transferring a computer-generated negative onto a surface of the elements.

Composite relief image printing elements

High-quality composite printing elements are prepared without the need for precise registration of constituent photocurable elements by disposing at least one photocurable element, and preferably a plurality of photocurable elements, upon a surface of a substantially planar carrier sheet in approximate register and then transferring a computer-generated negative onto a surface of the elements.

A method is provided for producing relief images having improved image fidelity and resolution. The method comprises positioning an image bearing negative transparency closely adjacent and substantially parallel to a layer of a photocurable material; positioning on the other side of the negative from the photocurable material and in substantially parallel relationship thereto at least one louver having a plurality of open cells, each cell extending through the louver along an axis perpendicular to the negative and having reflective side surfaces contoured to reflect and redirect rays of radiant energy incident thereon to a direction more normal to the negative surface; and passing radiant energy which is capable of curing the photocurable material through the louver and the negative and onto and through the photocurable material for a time sufficient to form a latent relief image in the photocurable material. The present invention is further directed to an apparatus for producing a latent relief image using the above method. The apparatus comprises, in sequence, a planar support for the photocurable layer, a negative in substantially parallel relation to the support, at least one louver which is positioned parallel in its major plane to the negative, and, immediately adjacent to the louver, a radiation source for irradiating the photocurable layer through the louver and the negative and effecting curing thereof. The method and apparatus of the invention are especially useful for the production of improved high resolution half-tone and line relief images.

A printing blanket having excellent lateral stability comprised of a carcass formed of one or more layers of woven fabric with low machine direction elongation characteristics, a nonwoven fabric attached to an upper surface of the lower most woven fabric layer, a compressible layer secured to the upper surface of the carcass and an ink transfer layer imposed upon the upper surface of the compressible layer. The blanket having a carcass containing a nonwoven layer comprised of continuous or discontinuous filaments, displays excellent cross machine direction elongation stability.
