Title: Electrophotographic toner carrier with fluorinated polyimide coating - with good charging property, adhesion, abrasion resistance and solubility in polar solvent
Inventor: HORIKOSHI YUZO
IPC: G03G9/113
Filed: 1993-06-23
Abstract: Toner carrier for an electrophotographic printer has a coating of fluorinated polyimide resin (I) contg. 5-60 (wt.)% F atoms. Pref. (I) has a solubility parameter of 9-12. It pref. is based on units of formula (II): R1 = a tetravalent organic gp., pref. of formula (III) or a deriv. of this, which may be fluorinated; R2 = a fluorinated divalent organic gp., pref. of formula (IV) or a deriv. of this: A = alkene, -CO-, -O- or a combinatoin of these; B = alkene, -O-, -SO2 or a combination of these. The coating contains over 20 (wt.)% (I). ADVANTAGE - The coating prevents the toner sticking to the carrier and is resistant to abrasion, so that the carrier retains satisfactory electrical and electrostatic charge properties and has a long operating lifetime. Compared with PTFE, (I) has better solubility in polar solvents, which facilitates coating; and higher adhesion to the carrier core (e.g. Fe, ferrite, magnetite, etc.), which is attained just by drying at ca. 200 deg.C, which rather than cure at e.g. 300-400 deg.C, which reduced the cost. No primer, e.g. acrylic or epoxide resin, is necessary.

Patent DE-4413121-A1 (DE)
Title: Method for separating enantiomers on chiral stationary phases by liquid chromatography in capillary columns
Inventor: SCHURIG VOLKER PROF DR
IPC: B01D15/38
Filed: 1994-04-17
Abstract: The present invention relates to a method for separating enantiomers by liquid chromatography in open capillary columns using chiral stationary phases. The chiral component used is, for example, a polysiloxane to which alkylated cyclodextrin ( alpha ,  beta  or gamma ) has been chemically bonded (e.g. CHIRALSIL-DEX) and which has been immobilised on the surface of the inner wall of the capillary. The method according to the invention is suitable for qualitative and quantitative analysis of enantiomers. In this respect there is no restriction to analytes which do not decompose on volatilisation as in capillary gas chromatography. A typical advantage of the method according to the invention is the smaller solvent usage, in the microlitre range, and the long lifetime of the arrangement used. The necessity, which is customary on use as addition to the mobile phase, of de novo preparation of the chiral separating component after each analysis run does not apply to the method according to the invention.

Title: Turbo-charged IC engine electronic management system
Inventor: GILE DAVID V
IPC: F02B37/00
Filed: 1994-12-08
Abstract: An IC engine management system has a microprocessor receiving input from a sensor for the exhaust gas temperature, and outputting a signal to the fuel injectors. This signal is also a function of the engine torque and throttle flap angle. The microprocessor compares the sensor signal with a predetermined throttle flap switching or release point. The control system then throttles the maximum available engine torque, so that the exhaust temperature exceeds the throttle flap release point.
