Title: Process for the preparation of n-carboxyalkyl-3-fluoro-4-dialkylaminoanilines
Inventor: SCHUBERT HANS
IPC: C07D295/12
Filed: 1998-02-17
Abstract: A process for the preparation of N-carboxyalkyl-3-fluoro-4-dialkylaminoanilines,which comprises reacting, in a first step, 2-chloro-4,5-difluoronitrobenzene of the formula (I) (see fig.I) with a secondary amine of the formula (II) HNR1R2, in which R1 and R2, independently of one another, are identical or different and are an alkyl radical having from 1 to 10 carbon atoms or, together with the N atom to which they are bonded, form a ring having from 5 to 7 members, in the presence of a water-soluble amine which forms hydrofluorides and hydrochlorides which are liquid at the reaction temperature and work-up temperature or soluble in the reaction mixture, in the presence or absence of a solvent at -10 to 120°C, reducing, in a second step, the reaction mixture containing the 2-chloro-4-dialkylamino-5-fluoronitrobenzeneusing hydrogen at from 30 to 150°C and from 1 to 350 bar in the presence of the water-soluble amine and in the presence of a noble-metal catalyst and, in a third step, reacting the reaction mixture containing the 3-fluoro-4-dialkylaminoaniline with a chloroformate of the formula (IV) ClCO2R3, in which R3 is an alkyl radical having from 1 to 10 carbon atoms or an aralkyl radical having from 7 to 20 carbon atoms, at from 0 to 100°C in the presence of the water-soluble amine.
Patent CA-2233832-A1 (CA)
Title: Business form with patterned silicone liner
Inventor: CHESS STANLEY C
IPC: B42D15/10
Filed: 1998-03-31
Abstract: A business form with labels, and a method of construction of the form, are provided. The form according to the invention includes a cellulose ply larger than a second, release liner ply, and the release liner ply may be provided so that one edge (e.g. with tractor drive holes therein) extends past a substantially parallel edge of the cellulose ply, and at the opposite edge of the release liner ply, adhesive release material is provided along between 10-50% of the length of the edge so that the release material covered portion of the edge is not substantially permanently adhered to the edge by the adhesive between the plies. This allows the labels die cut (or otherwise formed) in the cellulose ply, where overlapped by the release liner, to be removed from the back or the front, and also allows one to separate the release liner ply completely from the cellulose ply, if desired (after use) for ease of recycling since one can get a port ion started which allows breaking of the "permanent" bond between the cellulose and the release liner where no release material is provided on the release liner.

Filed: 1997-03-24
Abstract: An apparatus (figure 2) and method for forming a digital optical disc master from a disc having a substrate (300) coated with a photoresist coating (320).  The method includes irradiating the surface of the photoresist material (320) with a laser beam (310) at a multiplicity of pit locations over the substrate (300) causing the photoresist material (320) to react to the laser radiation (310) to form at least three different discrete levels at the multiplicity of pit locations relative to the surface of the substrate (300) due to the dose of radiation applied being calculated to react with the photoresist to a depth equivalent to the discrete levels. The exposed photoresist is then developed to achieve the pits having the different discrete levels. A further method is disclosed for equalization and compensation for intersymbol interference between adjacent pits.

Patent CA-2253469-A1 (CA)
Inventor: FAY THEODORE D
IPC: G01T1/202
Filed: 1997-04-03
Abstract: A scintillator detector apparatus (10) includes a sandwich (30) of fibers (14, 16) disposed in a spaced apart pattern for detecting one form of radiation while enabling another form of radiation to pass through open portions (20) between the fibers (14, 16) along with a thin film (24) attached to or proximate to the fibers (14, 16) for detecting the another form of radiation. The thin film (24) is disposed on a plastic substrate (26) which includes a reflecting layer (74) for directing scintillation from the film (24) into the fibers (14, 16). The fibers (14, 16) scintillate upon interception of, for example, beta particles, which is transmitted to photomultiplier tubes (40, 42) by the fibers (14, 16). The fibers (14, 16) are also sensitive to ultraviolet scintillation from the film (24) and respond thereto to generate scintillation which is also transmitted to the photomultiplier tubes (40, 42). Combinations of the sandwiches (30) may be utilized to formulate time of flight scintillation detectors and the sandwiches (30) can be responsive to various types of radiation dependent upon selected fibers (14, 16) and thin films (24).
