Abstract: The present invention is directed to a reciprocating motor pump (1) suitable to generate compressed gas with a reduced noise level of at most 55 dB, wherein said pump (1) includes a pump casing comprising:—a gas inlet nozzle (3);—a gas chamber;—a cylinder chamber (4) comprising a piston (5);—an inlet valve (7);—an outlet valve (8); and—a gas outlet port (9); wherein gas enters the gas chamber (2) through a gas inlet nozzle—(3) of said gas chamber (2) and then flows from said gas chamber (2) to said cylinder chamber (2) to said cylinder chamber (4) through an inlet valve (7) of said cylinder chamber (4), whereby the ratio of the diameter of the opening of the gas passage of said inlet nozzle (3) to the diameter of the opening of the gas passage of said inlet valve (7) is 1:15 to 1:5.

Abstract: A hot beverage making device comprises a boiler (10) for heating water; a housing (20) for accommodating the boiler (10) and other components of the device; and connecting means (30) for connecting the boiler (10) to the housing (20). During operation of the boiler (10), water is heated and water vapor bubbles are created inside the boiler (10). The formation of the bubbles causes varying moments about the center of mass of the boiler (10). The connecting means (30) are adapted to preventing transmittal to the housing (20) of at least a portion of the moment variations, in order to keep the noise produced as a result of vibrations of the housing (20) at an acceptable level. In particular, the connecting means (30) are adapted to let the boiler (10) have at least one rotational degree of freedom.

Abstract: The surface profile of, or distance to, an object can be accurately determined by scanning the surface (3) with an illumination beam (2) having a slit shaped cross-section and an intensity distribution in the slit width direction (= scan direction) and imaging the surface on an image sensor (5) comprising a number of pixels (51). By determining when a sensor pixel receives a maximum radiation intensity the position in the scan direction (x) of an illuminated surface area (31, 32) associated with said sensor pixel van be established and the height of this area can be measured by triangulation calculation.

Abstract: Generation of a granular graphic pattern on a physical surface is based on the multiple usage of elementary shapes. In particular, the method uses computer graphics in a multilevel pattern generation. It features defining at least two different absolute and/or relative transformation specifiers that are non-uniform amongst the elementary shapes with respect to either neighbouring ones of said elementary shapes and/or with respect to an overall geometry of the elementary shape in question. Finally, it applies the elementary shapes so specified on the physical surface.

Abstract: The invention relates to an electrical surface treatment device which is provided with an acoustic surface type detector with which a type of a surface to be treated can be detected during operation. According to the invention, the surface type detector delivers an output signal (u.sub.FT) during operation which is characteristic of the type of surface to be treated and which is determined by a value of a physical quantity of air vibrations reflected by the surface to be treated, which value is measured by a vibration detector of the surface type detector. In a special embodiment, the physical quantity is an amplitude, and the surface type detector is a vibration generator for generating air vibrations having a predetermined amplitude. The generated air vibrations preferably have a frequency of at least 15,000 Hz which varies within a predetermined range.

Abstract: A deep-frying device comprising a reservoir, a discharge channel for discharging fumes, and a converter for converting volatile organic compounds into carbon dioxide and water, has a passage for the admixture of ambient air to the fumes exuded during deep-frying. This provides an improved odour reduction. In the case of upstream admixture additional oxygen is available, as a result of which a more complete conversion is achieved. In the case of downstream admixture, conversion is possible at a higher temperature without a corresponding rise in the temperature of the discharged mixture.

Abstract: A vacuum cleaner comprises a suction unit (23) which is drivable by means of a first electric motor (25). A suction attachment (7) of the vacuum cleaner comprises a rotatable brush (41) which is drivable by means of a second electric motor (45). The vacuum cleaner comprises a control unit (29) by means of which an electric current through the first motor (25) can be controlled. In accordance with the invention, the control unit (29) controls the current through the first motor (25) as a function of a mode of operation of the brush (41), which mode can be selected by a user of the vacuum cleaner. In this way, the suction power of the suction unit (23) is adapted to the mode of operation of the brush (41), thereby improving a relationship between cleaning performance, ease of use, current consumption and noise production of the vacuum cleaner.
