Patent CA-2089097-A1 (CA)
Inventor: DORICA JOSEPH
IPC: C02F9/00
Filed: 1991-09-18
Abstract: A process for removal of adsorbable organic chlorine (AOX) in which the acid-soluble AOX present in kraft chlorination (CD) effluents (12) are destabilized and converted to inorganic chloride by pH shift using the alkalinity and acidity sources available at the mill; CD effluent, typically having a pH of 1-2 and E1 effluent (22), typically having a pH of 9-12 can be mixed in various proportions to achieve a pH between 6.5-9.0 or the CD effluent is adjusted in pH to 6-11 with an alkaline composition (23) so that alkaline hydrolysis as well as precipitation of organic material occurs and the treated effluent (26) contains less AOX than present in the original untreated effluents; the AOX removal is enhanced substantially by (i) the presence of a sulphide (20) or (ii) by carrying out the alkaline treatment at elevated temperature and pressure.

Title: Thermooxidative stabilization of polyolefins with an oxo-piperazinyl-triazine and a phosphorous acid ester
Inventor: KLETECKA GEORGE
IPC: C08K5/524
Filed: 1991-09-06
Abstract: Only two symmetrical stabilizers in a polyolefin or copolymer thereof, provide thermooxidative (''TO'') or antioxidative (''AO'') stability. One is a phosphite or fluorophosphite; the other is a monomolecular tri-substituted triazine in which each of three chlorine atoms on a trihalo-s-triazine is substituted with a piperazinone in which the N atom in the 4-position is alkylated. Only a trace amount of phosphite, from 0.01 phr to no more than 0.1 phr, is used; additional phosphite has no noticeable effect. The trace amount of phosphite has a surprising booster effect, giving the stabilized composition excellent TO stability. Articles thermoformed from the stabilized polyolefin or copolymer thereof may be used under the hood or the dash of a vehicle, and, in containers for packaging goods, all of which articles are subject to TO  degradation even if they are not subject to ultraviolet light degradation.

Abstract: A retro-fit temperature compensating device (T.S., JP3, JP2, J1, S) regulates the output voltage (V) of a rectifier (R) or "charger" connected to a rack or bank  (B) of serially connected batteries (BAT).  The temperature (T) of the battery (BAT) is sensed (S) and the temperature compensating device (TS) regulates the effective voltage (V) applied by the rectifier or charger (R) to the battery terminals  (JP2, JP1) according to a pre-selected slope  (figure 2) as the manufacturer may have determined from a referenced temperature, generally fixed at 25 °C.   The device (TS, JP3, JP2, JP1, S) may be retro-fitted to existing charging units (R) and the device maintains the float voltage on, for instance, a 48V battery string (B) at the manufacturer's recommended charge rate, having a deviation or slope, of 72 mV for every  °C of temperature change about the reference voltage 25 °C of the string (B) or single battery (BAT); hence, life expectancy of each battery (BAT) of the string (BB) for the full life term of 10 years may be more adequately achieved.
