Title: Novel methods for the preparation of trisaryl-o-hydroxyphenyl-s-triazines
Inventor: ACKERMAN MICHAEL
IPC: C07D251/24
Filed: 1999-02-26
Abstract: A process for preparing 2-(2,4-dihydroxyphenyl)-4,6-diaryl-s-triazines or related compounds in three steps starting with cyanuric halide or corresponding phenoxy or alkoxy substituted triazine is described. Step 1 involves the nucleophilic displacement of one or two leaving groups in the triazine with a phenolic moiety. Step 2 involves a Friedel-Crafts reaction using a Lewis acid catalyst (preferably aluminum chloride) to replace the remaining leaving groups) with aryl groups such as xylyl. Finally, step 3 involves replacing the phenolic moiety with a phenol such as resorcinol using preferably a protic acid catalyst or a combination of a Lewis acid and a protic acid catalyst. Alternatively, step 3 may be performed alone, e.g. starting from materials from other processes, or leading directly to a tris-hydroxyphenyl-s-triazine.  The s-triazines prepared are useful as UV absorbers for the stabilization of organic substrates against the adverse effects of actinic light.

Title: Weapon system employing a transponder bomb and guidance method therefor
Inventor: OXFORD STEPHEN C
IPC: G01S13/00
Filed: 1998-06-26
Abstract: A launch aircraft (30) launches a bomb (10) at a target (36) and uses a radar (31) to transmit a predefined waveform (35) at the bomb (10) and target (36). The bomb (10) incorporates a transponder that frequency shifts the transmitted waveform and illuminates the target with a shifted waveform (33) having a null at the center of its beam pattern.  The initially transmitted waveform and frequency shifted waveform are reflected from the target and are received by the radar. The received signals are processed to generate a correction signal (32) that is a function of the offset between the null of the frequency shifted waveform and the target location. The correction signal is transmitted to the bomb and is processed therein to correct the flight path of the bomb toward the target.

IPC: C08L83/04
Filed: 1998-04-23
Abstract: Article absorbant, tel qu'une couche, doté de parties tour des jambes enduites d'une lotion. Les lotions décrites par l'invention réduisent l'abrasion entre les parties élastiques entourant les jambes et la peau dans les régions dans lesquelles ces parties entrent en contact avec la peau de l'utilisateur, ce qui diminue l'irritation cutanée. Ces lotions réduisent en outre l'adhérence des matières fécales à la peau, ce qui facilite le nettoyage. La lotion contient un émollient constitué de polysiloxane plastique ou fluide tel qu'un polyméthylsiloxane à fonction phényle, un agent fixant tel qu'un alcool gras ou une cire de paraffine pour fixer l'émollient à la surface des partie tour de jambe de la couche, et éventuellement un tensioactif hydrophile pour augmenter la facilité de manipulation et/ou la stabilité des compositions de lotion. Etant donnée que l'émollient constitué de polysiloxane est sensiblement fixé sur la surface de la partie tour de jambes, une quantité moins importante de lotion est nécessaire pour obtenir les effets protecteurs ou thérapeutiques désirés.
