Patent EP-0053594-A1 (EP)
Inventor: JENSFELT TORSTEN ELI
IPC: C22B5/02
Filed: 1981-11-27
Abstract: Lead is recovered from sulphidic lead raw-material containing impurities of the kind bismuth, arsenic, antimony and tin, by flame-smelting the material with an oxygen-containing gas. The oxygen potential and temperature are adapted during the flame-smelting process so that the product formed thereby comprises substantially a lead-sulphide melt substantially free of volatile, sulphidic and metallic impurities of the said kind. The lead-sulphide melt is brought into contact with an oxidic lead material substantially free of impurities of the aforementioned kind, while oxidising the sulphide-sulphur content of the material and forming a melt substantially free of sulphur. Lead is recovered from the melt by separation, optionally after subjecting the melt or a part thereof to a reducing process.

Abstract: Objects constituted by a porous web-like material, such as a paper web, a granular material, such as peat, or a solid material such as wood, are dried by placing the same in contiguity with a fine porous liquid suction surface which itself is in liquid communication with a liquid volume with the latter being in communication with apparatus by which the liquid in the liquid volume is maintained at an underpressure relative to the pressure of the liquid in the object to be dried so that liquid flows from the object into the fine porous suction surface. The liquid flow can be enhanced through the application of an over pressure or through the direction of radiation onto the object to be dried. In one embodiment, the fine porous liquid suction surface comprises the surface of a rotatably mounted cylinder whereby a web-like object, such as a paper web, can be dried as the same is carried on the cylinder surface.

Abstract: In a first embodiment (Figure 1) an electronic ballast system is provided for two gas discharge tubes (202, 202'), the ballast system comprising a first transformer (238) powered by an AC source (204) via wave bridge (218). Transformer (238) comprises primary and secondary windings (240 and 242) which establish an oscillating signal. Two transistors (256, 258) are coupled in feed-back relation to the transformer for switching a current signal in response to the oscillation signal. Two inverter transformers (210, 212) establish an induced voltage signal responsive to the current signal which is passed to the tubes via capacitors (308, 310). Capacitance tuning circuits embodying capacitors (312, 314; 316, 318) serve to modify the resonance frequency and duty factor of the signal pulse generated by each inverter transformer. 
     In a second embodiment, Figure 2, tube (12) is powered by a ballast system comprising transformer (T) connected to AC power source (14) via rectifying diode (D,). Primary winding (22) of transformer (T) is connected in series with the power source (14) and filament (30) of tube (12) via capacitor (C 2 ). Secondary winding (24) of transformer (T) is connected in positive feed-back relation with the base (44) and emitter (42) of a transistor (Tr). The collector (38) of the transistor (Tr) is connected to the capacitor (C 2 ). Second capacitor (C 3 ) is connected in series with the transformer secondary winding (24) to apply a pulse voltage to the second filament (32) of the tube (12).

Abstract: Die Alarmanlage dient zur Erfassung von ungewöhnlichen Zuständen wie z.B.

Der Lichtstrahl wird für die Uebertragung der Signale verwendet, die die ungewöhnlichen Zustände anzeigen. Hierdurch werden die Anzahl der für diese Signal-Uebertragung notwendigen Leitungen verringert und die Signal-Uebertragung selbst unempfindlicher gegenüber elektrischer Störungen gemacht. Zu diesem Zweck enthält der Lichtprojektor einen Signal-Eingangskreis mit einem Codierer (23), einem Serien/parallel-Umwandler (24) oder dergleichen für den Empfang des zu Übertragenden Signales und einem Modulator (25) zur Modulation des Stromes der Lichtemission mit dem Ausgangssignal des Signal-Eingangskreises.

Wenn mehrere Rauchmelder in Kaskade verbunden sind, wird das Signal, das den abnormalen Zustand anzeigt, über die Lichtstrahlen eines jeden von mehreren Rauchmeldern bis zur Empfangseinheit (4) übertragen.

Abstract: The invention is an improved specially designed wrapper construction for smoking articles producing controlled bum properties of smoking articles such as cigarettes so that the cigarette will self-extinguish after free burning in air for a designed time period. In addition, the wrapper construction results in cigarettes with reduced tendency to ignite combustible substrates, such as upholstered furniture, when in contact with them. Therefore, smoking articles with this wrapper construction reduce the likelihood of accidental fires, yet they free-bum rapidly for a designed period of time without puffing. However, during a normal puffing sequence the behavior of cigarettes with these wrappers is indistinguishable from commercial cigarettes. On the other hand, other self-extinguishing cigarettes go out without puffing and therefore have to beTelighted frequently. The wrapper constructions of the present invention include single (14) or double wraps (14A, 14B) of cigarette paper (16) which are inherently incapable without elevated levels of bum promoting chemical of supporting cigarette free bum. The construction is modified by application of a plurality of zones (18) of elevated levels of bum promoter to the extent that the cigarette bums normally in the treated zones (18). Thus, when the burning coal advances to an area of untreated wrap, it reliably self-extinguishes unless puffed. The extent of the treated zones (18) controls the time required for the cigarette to self-extinguish. Required wrappers are preferably those having a Burn Mode Index ("BMI") as defined in the range of from about 1.5 cm-' to about 6.0 cm-' for the single wrap embodiment and, forthe double wrap embodiment, about 0.1 cm -1 to about 4.0 cm -1  for the inner wrap and about 2 cm -1  to about 40 cm -1  for the outer wrap depending on the BMI of the inner wrap. The wrappers and smoking articles of the invention may be produced using conventional methods and equipment.
