Abstract: The invention relates to a method for manufacturing an inlet lip skin part according to a nominal definition comprising dimensions of the lip skin and associated tolerances, the method comprising the steps of: a) obtaining at least one blank from at least one metal sheet; b) deforming the at least one blank into an intermediate part; and c) machining a first surface of the intermediate part with a first machining path, said first machining path being independent of the real dimensions of the intermediate part, and being based on the nominal definition of the lip skin part, so as to obtain a semi-machined part, and d) machining a second surface of the semi-machined part with a second machining path, said second machining path being based on real dimensions of the semi-machined part and the nominal definition of the lip skin part.

Abstract: An inductive heating arrangement to heat an aerosol-forming substrate is provided, including: a DC power source and power supply electronics including a DC/AC inverter connected to the power source, the inverter including a resonant switching power amplifier with a transistor switch, a transistor switch driver circuit associated with the switch and an LC load network including a capacitor and an inductor to generate an alternating magnetic field, the driver circuit including a tunable oscillator to output a switching signal to the switch having a tunable switching frequency; a current sensor to determine a DC supply current drawn from the power source; and a controller to receive a current signal from the sensor indicative of the supply current and to tune the frequency of the switching signal in response to the received current signal in order to tune the supply current to be in a predetermined range.

Abstract: A dry vacuum pump includes an elastic outer seal and at least one elastic inner seal respectively including a first and a second end annular parts parallel to one another and inserted between a respective end piece and the half-shells, and two side rails connecting the end annular parts and which are at right angles thereto, the side rails being inserted between the half-shells, the at least one inner seal being arranged inside the outer seal so that the at least one inner seal and the outer seal form at least two successive sealing barriers for the gases.

Abstract: The machine includes a fixed disk (2) comprising a spiral wall (3), a mobile disk (4) also comprising a spiral wall (5) cooperating with that of the fixed disk, and means (11, 16, 22, 23) for driving circular translation movement of the mobile disk, the mobile disk being positioned axially by a system including a shoe (25, 32, 36) rubbing between two lateral abutments (26, 27-34, 35-39, 40), one member of the pair of members (i.e.

Abstract: A scroll type machine including a fixed disk (5) comprising a spiral working wall (6) and a mobile disk (7) equally comprising a spiral working wall (8) cooperating with that of the fixed disk, means for driving circular translation movement of the mobile disk, a sealing bellows (15) joined at one end to a member (14) fixed with respect to the circular translation movement of the mobile disk (7) and at its other end to a fixed part (1C) of the machine, said bellows (15) separating the fluid circuit from the mechanical parts driving the mobile disk, characterized in that the fixed disk (5) is joined on the side opposite the mobile disk (7) to a fixed central shaft (10) including a discharge passage (11), said central shaft being surrounded by said bellows (15), the space (16) between said bellows and said fixed central shaft constituting a suction passage, in that a hollow main rotary shaft (19) surrounds said bellows (15) and is carried by at least one bearing (23, 24-32) in a fixed frame (1), one end of said

Abstract: An evolutive coding process using a pseudo-random discontinuous function for coding remote controls, such as for automobiles. A message containing at least two pseudo-random values calculated by the pseudo-random discontinuous function is transmitted. Preferably the pseudo-random values are successive values of the pseudo-random discontinuous function, and the message optionally includes a code derived as a function of a specific base code associated with the system. The general preferred form of complete code message may take the form T(C) plus FA(C,n-1), plus FA(C,n) where T is a continuous function and FA is a pseudo-random discontinuous function.

Abstract: An infrared transmitter of coded message is provided having a fixed code and large number of combinations particularly but not solely for use in the automobile industry.The transmitter comprises a series programmable electronic memory (1), the content of which is addressed by a pulse transmitter (2), an oscillator or timer, the content of the memory (1) being supplied to a pulse generator (3) supplying an amplifier (4), the output of which is transmitted to a transmitter diode (5), the content of the memory (1) being supplied, in addition, to an end of message blocking device (6) controlling the reading pulse transmitter (2).
