Abstract: A robotic arm includes a base, a first robotic arm, a second robotic arm, a robotic hand and a cigarette holder connected in sequence. The cigarette holder includes a cigarette insertion hole and a cigarette smoking tube. The cigarette smoking tube is connected to a smoking simulator. The robotic arm further includes at least one air exhausting hole. The air exhausting hole is located around the cigarette holder and communicated with an air exhauster through an air exhausting pipe. The robotic arm swings to control the cigarette holder to carry a cigarette from a smoking position to an ash flicking position. Airflow is formed near the air exhausting hole by means of air exhaustion, so as to simulate influences of a wind speed in an outdoor environment on the columnar ash in the cigarette smoking process of the human body.

Abstract: A smoking path simulation system includes a case, the robotic arm fixedly provided in the case and a cigarette holder mounted at a working end of the robotic arm, and further includes a feeding device, a cigarette tapping device and a cigarette lighting device provided in the case and located at a periphery of the robotic arm, as well as an image acquisition device mounted at the working end of the robotic arm. With the smoking path simulation system, an action path of smoking a cigarette by a consumer may be simulated, and consistency of the simulated action paths may be guaranteed, thus effectively improving precision of test of indexes of a cigarette-combustion performance, such as cigarette-combustion ash integration characteristics, or the like.

Abstract: A high-transparence fiberglass paper includes vegetable parchment which is successively coated with a base layer, a second layer and a protective layer on both sides. The base layer and protective layer are prepared using water-based paints, while the second layer is prepared using UV ink through curing. The transparency and surface smoothness of the fiber is thereby greatly improved. Through treatment on the both surfaces, the paper can be processed into a light and smooth paper, with a surface smoothness of both sides more than 200 s, just like hyaline paper.

Abstract: The present invention provides a low-loss high-repetition-rate pulsed laser modulator comprising: a 2*2, 1:1 coupler; a light delay module; a 1*2, 1:1 coupler. The present invention can modulate a low-repetition-rate pulsed laser to be a high-repetition-rate pulsed laser. The basic principle is: one beam of low-repetition-rate pulsed laser can be divided into two beams with the same light intensity by a 1*2, 1:1 coupler; control the two beams of light to have an optical path difference so that when they are coupled into a 2*2, 1:1 coupler, a double pulse repetition rate can be obtained; In the same way, when the two beams of light from former 2*2, 1:1 coupler, with another different optical path difference are coupled into the next 2*2, 1:1 coupler, a double pulse repetition rate can be obtained again; when we obtain the repetition rate we need, a 1*2, 1:1 coupler instead is connected to couple the two beams of light into one beam with a double repetition rate.

Abstract: A steam ironing device (1) comprises a steam generator (20) for heating water to steam, a steam outlet (25) for letting out a burst of steam (27) from the steam generator (20), a device (30) for supplying water to the steam generator (20), a hose (40) connecting the water supplying device (30) to the steam generator (20), and a controller (50) which is adapted to operating the water supplying device (30) during a period of time in a situation in which there is hardly any need or no need at all of a supply of steam in an ironing process, while keeping the steam outlet (25) closed. In this way, a reserve amount of steam is generated, which is stored in an internal space (21) of the steam generator (20), and, as the occasion arises, inside at least a portion of the hose (40). When a burst of steam (27) is required, the reserve amount of steam is released through the steam outlet (25).

Abstract: A steam iron comprises a soleplate (1) and a separately arranged steam generator (30) having heating means (31) for heating a content of the steam generator (30). The soleplate (1) comprises an embossed area (11) for distributing the steam. As the soleplate (1) does not play a part in the process of generating steam, and does not need to comprise additional means for distributing steam, it is designed in a relatively lightweight manner, which has the advantage that the time needed for a temperature change of the soleplate (1) is relatively short. On a top surface of the embossed area (11), heating tracks for heating the soleplate (1) are arranged. As the top surface of the embossed area (11) is not capable of directly touching other objects, for example objects to be ironed, situations in which the heating tracks are subjected to severe thermal shocks are avoided.

Abstract: The invention provides an ion exchange cartridge (13), in particular for a domestic appliance that comprises between a water inlet (1A) and a water outlet (2A) a weak acid ion exchanger in the H+ form (5), followed by a strong acid ion exchanger in the Na+ form (7). This cartridge may be compact because it removes hard scale forming ions only. The cartridge may further comprise a first (16) and a second probe (17) to measure hard scale causing ions by a differential measurement of the conductivity of incoming water and water that has passed one or both ion exchangers. Herewith the appliance can be switched off when the cartridge is not functioning anymore, thus forcing a user to replace the cartridge, or to regenerate the ion exchangers before hard scale blocking of the appliance.

Abstract: A steam generator (1) comprises a body (20) in which a spiral-shaped groove (30) is arranged, as well as a connection channel (32) which provides access to an end portion (33) of the spiral-shaped groove (30) from a circumferential surface (21) of the body (20). For the purpose of closing the spiral-shaped groove (30), a cover is provided, which has a hole for providing access to a central portion (31) of the spiral-shaped groove (30). During operation of the steam generator (1), water is supplied at one of the central portion (31) and the end portion (33) of the spiral-shaped groove (30). Under the influence of heat, steam is generated, which exits at another one of the central portion (31) and the end portion (33) of the spiral-shaped groove (30).

Abstract: A steam iron having a soleplate and a steam generator comprises a heater circuit (40) having two parallel loops (44, 45), wherein a main soleplate heating element (41) is arranged in a first loop (44), and wherein an auxiliary soleplate heating element (42) and a steam generator heating element (43) are arranged in a second loop (45). In the second loop (45), a selector switch (46) is arranged, for either connecting the auxiliary soleplate heating element (42) or the steam generator heating element (43) to an electric power source (50). A position of the selector switch (46) is determinative of an operating condition of the heater circuit (40). In one possible operating condition, both soleplate heating elements (41, 42) are connected to the electric power source (50). In this operating condition, the soleplate is heated up fast, as all available electric power is used for heating the soleplate.
