Abstract: Compounds of formula (I): ##STR1## in which: Q is nitrogen or .dbd.CH--; R.sup.1 and R.sup.2 are hydrogen, alkyl, alkoxy, hydroxy, trifluoromethyl or halogen; and R.sup.3 is a substituted alkyl groups, or a pharmaceutically acceptable salt thereof have valuable anti-allergic and anti-asthmatic activities. The compounds are prepared by reacting a corresponding compound where R.sup.3 is replaced by a hydrogen atom with a compound to introduce the group R.sup.3.

Abstract: A cathodic electrodeposition paint containing as a binder resin an amine-epoxy resin adduct and a blocked polyisocyanate crosslinker is disclosed. The binder resin and the crosslinker are emulsified in an aqueous medium containing a neutralizing agent with the aid of amine adduct of a monoepoxide compound having a hydrophobic group or block. Not only the amine-monoepoxide adduct functions as a surfactant but also it is deposited electrically and then cured with the crosslinker integrally with the binder resin.

Abstract: Compounds of formula (I): ##STR1## [wherein: A-- B is .dbd.C.dbd.CH--or a nitrogen atom; R.sup.1 is hydrogen, alkyl, aryl or aralkyl; and Z is alkylene] and pharmaceutically acceptable salts thereof are useful in the treatment and prevention of allergies and asthma.

Abstract: A drying machine has a drying chamber for drying an article cleaned with an inflammable solvent as a detergent. A hot air supply channel communicates with the drying chamber and a heater is mounted in the hot air supply channel. A hot air evacuation channel communicates with the drying chamber and a hot air transfer device is mounted at a voluntary portion of the hot air supply channel and the hot air evacuation channel. A control device is provided for driving control of the heater. A first temperature sensor is mounted on the downstream side of the heater in the hot air supply channel and a second temperature sensor is mounted at a position shifted to the drying chamber in the hot air evacuation channel. The control device controls the heater so that the difference in the temperature detected by the first temperature sensor and the temperature detected by the second temperature sensor is kept within a safe temperature range.

Abstract: Compounds of formula (I): ##STR1## in which: R.sup.1 and R.sup.2 are independently alkyl, alkoxy, trifluoromethyl, nitro or halogen; A is an aliphatic hydrocarbon group having from 2 to 8 carbon atoms whose chain contains at least 2 carbon atoms in a linear chain between the piperidine group and --COOH, said group optionally being unsaturated; and m and n are independently 0, 1, 2 or 3; and pharmaceutically acceptable salts and esters thereof have been found to have valuable anti-histamine properties without the usual side effects of anti-histamines. Methods of preparing the compounds are also provided.
