Title: Film processor
Inventor: MORSE JOHN B
IPC: G03D9/00
Filed: 1984-02-24
Granted: 1987-07-16
Abstract: Apparatus for processing individual rolls of self-developing type transparency film. The apparatus includes a spool having a first post, to which the leaders of a length of photographically exposed film and a length of flexible sheet material are adapted to be attached, and a second post, to which only the leader of the film is to be attached. The spool is adapted to be rotated so as to wind upon the spool a laminate comprised of the film, the sheet material, and a layer of processing liquid sandwiched therebetween for a period of time sufficient to form a visible image in the laminate. After formation of such image, the laminate is unwound from the spool and the film stripped from the sheet material as they are being rewound into their original containers. The posts are constructed such that the leader of the sheet material will automatically become detached from the first post at the end of the unwinding of the laminate thereby allowing the sheet material to be returned completely to its container while the second post maintains its attachment to the film leader. Thus, when the film leader is manually detached from the second post, it is available for withdrawing the processed film from its container for subsequent cutting and mounting of the film's individual frames.

Patent DE-3584761-D1 (DE)
Inventor: ELLIS HAROLD
IPC: B32B13/00
Filed: 1985-04-23
Granted: 1992-01-09
Abstract: A novel, non-combustible thin coating, applied as an air-setting paint, is used to form a coherent fire-barrier on or between susceptible wood or plastic substrates, or other substances. Consisting of a paint-like slurry of three separate but compatible and mutually synergistic co-bonding systems, viz. magnesium "oxychloride" cement, plus high alumina mono-calcium aluminate cement, plus colloidal silica dispersed in dimethyl formamide (DMF), and utilizing an aqueous solution of magnesium chloride as the common hydrating fluid for the two cements, the coating retains its structural integrity through prolonged exposure to flame temperatures of 2000 DEG  F. The coating takes advantage of its brilliant whiteness to act as a thermal radiation reflector for the high radiation component of most flames. Used alone, or in combination with structural reinforcing geotextiles, such as non-woven spunbonded polyester fabric, or woven and non-woven fiberglass or other natural or synthetic fabrics to form a laminate, the coating, while serving only transitorily as a heat barrier, effectively prevents the ignition of and flame spread of fire on the coated substrate. When placed between substrates at the partial sacrifice of the surface directly exposed to flame, it protects the back-substrate, and thus maintains structural integrity, as well as preventing the spread of flame to adjacent areas. The coating thus acts as a "fire-barrier" for which there are numerous applications.
