Abstract: A pillow for sleeping on one's side that comfortably accommodates the user's shoulder by having an indentation at a middle section of the pillow. The indentation is created by a first interior face and a second interior face that tapers inwardly towards a center axis from lateral sides of the pillow. The first and second interior faces also taper from a top side towards the bottom side of the pillow. The indentation can be replicated on the opposite side so that the pillow can be reversible.

Abstract: A triune, substantially bilaterally symmetrical pillow for a reclining human being is configured to provide therapeutic and support and comfort for the head and neck while lying on one's back and side, and allow use in two, opposite orientations to increase durability and functional capacity. A center section is provided with a thin portion, abutted on either side along one axis by two substantially similar convex portions, and abutted on either side along a second axis normal to the first by two substantially identical flat end sections. The end sections have cutaways near the bottoms of their sides, to either side of their connections to the center section, that are designed to accommodate the shoulder of a human user. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

Abstract: A method and apparatus for ultrafiltration, washing and concentration of photographic emulsion uses the Blatt Stagnant Film Theory using a gelatin-based mass transfer coefficient of the feed, gelatin concentration of the feed and a setpoint of a constant concentration at the ultrafiltration membrane wall. A useful permeate flow is achieved by varying the pump speed and membrane pressures.

Abstract: An ambulatory traction system which is designed to provide decompressional forces to the lumbosacral spine, lower body and related connective tissues at varying speeds from static to ambulation speeds up to 12 MPH. The ambulatory traction system has an overhead support assembly for horizontal linear displacement and a novel harness assembly suspended from the overhead support assembly to support and suspend the patient's body. A variable ambulation speed system is provided beneath the harness assembly which allows the patient, while being suspended by the harness assembly, to stand, walk or run thereon.

Abstract: In order to reduce microphony due to the piezoelectric nature of a pyroelectric element (9) in a pyroelectric detector, the detector comprises one or more flexible films resiliently supporting the element (9) and two electrical connections thereto each comprising an electrically conductive layer (6,8) on the film(s). There are suitably two films with the element (9) therebetween. The films are secured to one another around the element (9) by an adhesive, thereby urging the films against the element (9) to hold it in position and maintain the electrical connections.

Abstract: A bolometric detector comprising an optical immersion lens and a pyroelectric detector element mounted so as to be spaced from the lens. The detector may be mounted spaced from the lens by an air gap, by a foraminous spacer, or by a cement having a low thermal conductivity.
