摘要： A smoke detector, especially for a fire alarm, comprising a radiation source possessing a substantially conical ring-shaped radiation characteristic or pattern and a radiation receiver arranged along the axis of the radiation source but externally of the direct radiation. The radiation receiver receives radiation which is scattered by smoke particles within the conical ring-shaped radiation region. In order to reduce the spurious radiation impinging on the radiation receiver the radiation region is bounded by elements located externally of the direct receiving region of the radiation receiver. Web means (which comprise the bounding elements opposite the radiation source) are provided which are specially-shaped to prevent dust from collecting on their radiation receiving surfaces, thereby keeping the smoke detector from becoming increasingly susceptible with time to the triggering of false alarms as the deposition of dust at the inner surface of the fire detector housing increases.

摘要： A process for the dyeing or printing and simultaneous finishing of cellulose materials is disclosed the said process comprises impregnating these materials with an aqueous liquor containing a specific dyestuff which contains at least one bis-hydroxy-alkylamino group bound to a pyrimidine or triazine nucleus and bridged via an amino group to the dyestuff molecule, synthetic resin forming intermediate or aminoplast, an acid catalyst and optionally further additives, thereupon drying the thus impregnated material or steaming or storing at room temperature and finally subjecting it to a treatment at elevated temperature and optionally washing.The dyeings thus obtained have especially very high fixing yields of the dyestuffs and are moreover fast to light and to washing and have further finishing effects such as, e.g. improvement of the handle and resistance to shrinkage.

摘要： In a jet pump, the suction pressure (Po) generated may be kept constant within predetermined limits and times by varying the pressure ratio f(p) providing a prescribed value for the pressure ratio f(p) is determined by computer-aided iterative changing of an existing value of the pressure ratio f(p) using an algorithm and a measured value for the pressure (Pe) of the delivery fluid.

摘要： Fiber-reactive, heavy metal-containing formazane dyestuffs are disclosed which are tricyclic and wherein the heavy metal is a metal of an atomic number ranging from 24 to 30 and is bonded via a --COO-- and --O-- substituent to different diazo components and to the terminal nitrogen atoms of the central formazane bridge portion ##STR1## wherein R represents an optionally substituted aliphatic hydrocarbon radical, a cycloaliphatic radical or a carbo- or heterocyclic-aromatic radical, one of the aforesaid diazo components or the radical R bearing the fiber-reactive substituent. These dyestuffs are useful for the dyeing and printing of textile materials, and also of synthetic materials for other then textile uses. The dyestuffs may contain or may be free from watersolubilizing groups the former being especially useful for the dyeing of leather, paper, and natural or synthetic polypeptide fiber materials, as well as for the dyeing and printing of material or regenerated cellulosic fiber materials, especially cotton. Dyestuffs in which this fiber-reactive substituent is a pyrimidyl amino radical containing at least one fluorine atom are distinguished by their high reactivity; dyeings or prints obtained therewith are very stable vis-a-vis acid or alkaline hydrolysis and exhibit very good fastness to light, milling and wet treatments.
