Inventor: ROSENBURGH JOHN H
IPC: G03D3/02
Filed: 1994-04-12
Abstract: A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel.  The channel is formed by a repeating combination of squeegee pinch rollers and impingement slot nozzles.  Photographic processing solution is introduced through the impingement slot nozzles and the squeegee pinch rollers are used to remove the processing solution from the photosensitive material and provide transport of the photosensitive material.  Solution level control is achieved by drains positioned below the tops of the upturned sections.  The slot nozzles and the pinch rollers work interactively to break down the chemical barrier layer.

Title: Multi-Lavatory System
Inventor: BARNUM THOMAS G
IPC: E03C1/01
Filed: 1994-04-21
Abstract: A multi-lavatory system is preassembled to facilitate efficient installation with a minimum of connection points.  The multi-lavatory system is connected to a single fluid supply line and a single drainage line.  A fluid supply network conducts water from the single fluid supply line to a plurality of lavatory stations.  Similarly, a drainage network conducts waste water from the plurality of lavatory stations to the single drainage line.  Additionally, the multi-lavatory system includes a unitary lavatory subassembly having interconnected but spaced sink regions.  Each sink region is disposed in one of the lavatory stations and is bounded at a frontal area by an upstanding contoured wall that creates an independent washing zone.  This facilitates efficient production of the unitary lavatory subassembly and overall multi-lavatory system while providing each user of the system with a sense of privacy in their own independent washing zone.

Title: Diameter and lateral position sensitive nip pressure controls in a paper winding system
Inventor: FITZPATRICK DONALD C
IPC: B65H18/26
Filed: 1993-01-26
Abstract: A rider roll system for exerting an even nip load force along the surface of a roll of paper (24, 324) being wound from a continuous on-coming web (W) in a winder comprises a plurality of rider roll wheel elements (30a, 30b, 30c,... 330), each of which is connected to a common source (76, 376) of hydraulic pressure to provide the same rolling nip force against the wound paper roll (24, 324). The rider roll wheel elements (30a, 30b, 30c,... 330) are mounted to a beam (22, 322) which is translationally movable above the wound paper roll (24, 324). The beam (22, 322) and individual rider roll wheel elements (30a, 30b, 30c,... 330) are moved upwardly as a function of the increase in the diameter of the wound paper roll (24, 324). The relationship of the beam (22, 322) movement relative to the diameter of the wound paper roll (24, 324) is controlled by a programmable logic controller (84, 384). The individual wheel elements (30a, 30b, 30c,... 330) are loaded against a counter-balance force (52a, 52b, 52c,... 352) so as to provide equal, but cushioned, nip force against the surface of the wound paper roll (24, 324) at short intervals along its length. The magnitude of the evenly applied nip load force is also controlled as a function of the wound paper roll (24, 324) diameter.

Title: Improvements in or relating to rotary kilns
Inventor: CARTER ROBERT
IPC: F27D25/00
Filed: 1994-05-04
Abstract: A rotary kiln, particularly for producing uranium dioxide from hexafluoride, has an inlet arrangement (1) a heated rotatable barrel (14). Uranium hexafluoride  and steam react together in the inlet arrangement (1) to form uranyl fluoride which is fed into the barrel (14) by the aid of a rotating scroll feed device (17). In the barrel, the uranyl fluoride reacts with a counterflow  stream of steam and hydrogen to produce the uranium dioxide. A porous metal or ceramic filter (28) closely surrounds the scroll feed device (17) to remove particles from kiln-produced gases. The filter is maintained in a clean condition by the scraping action of a number of helical blades forming part of the scroll feed device (17). The uranium dioxide powder produced by the kiln may be processed to form nuclear fuel pellets.
