Title: Gas light control apparatus
Inventor: KOZIOL WALTER
IPC: F16K31/06
Filed: 1994-11-22
Granted: 1998-09-22
Abstract: A dimmer device for a gas light which is solar activated and is composed of a minimum number of parts.  A magnetically operated valve with a magnetically attractable ball is energized during daylight hours to close off one passageway yet allows gas to flow through a second passageway at a lower flow rate to provide a dimmer condition for the lamp.  At night time, the magnetic valve is deactivated causing the magnetic ball to open the otherwise closed passageway and thereby allow full gas flow to the lamp.  The dimmer device is easily installed into the lamp housing rather than the post.

Title: Implementation of dissolved solids profiling
Inventor: MARCOCCIA BRUNO S
IPC: C08B15/00
Filed: 1994-07-20
Granted: 2004-03-02
Abstract: Digester systems for producing paper pulp from comminuted cellulosic fibrous material take into account the level of dissolved organic materials (DOM), such as lignin, hemi-cellulose, and cellulose, maintaining the DOM level at about 100 g/l throughout the cook (particularly kraft cook) . In order to make sure there is sufficient liquid to slurry the material in t he feed system of a two vessel system, some liquid is withdrawn from the circulation conduits between the digester and impregnation vessel, cooled, and fed to the feed system. In a vapor phase digester, the level of liquid a t the top of the digester is more precisely controlled by circulating some of the withdrawn liquid from a circulatory loop of the digester to the level tank associated with the feed system. An in-line drainer may be provided in the feed system between a make-up liquor pump and a liquid inlet conduit leading to the top of an impregnation vessel. Within the digester, a set of extraction/dilution screens is provided specifically positioned and spaced from each other, and with respect to a reintroduction conduit opening, so th at mixing of different DOM concentration liquids is minimized.
