Abstract: The one-piece snap closure made of plastic for the opening of a container is provided with a sealing lever (3) above a covering plate provided with an opening, which sealing lever is articulated to a spring hinge (2) which is connected to the upper side of the closure in an articulated manner via a swivel connection (16). The sealing lever (3) and the spring hinge (2) are of approximately rectangular construction and, in the closed position, fill a diametrical incision in the upper side of the closure together with guide cylinders (7) of the swivel connections of the spring hinge (2) in such a way that the upper side of the sealing lever (3) and of the spring hinge are in alignment with the upper side of the closure. The upper side of the closure extends tangentially above two guide cylinders (7) of the sealing lever (3) which are connected eccentrically along a line (17) of the outer surface to the swivel connection (15) between the sealing lever (3) and the spring hinge (2) and engage in insertion openings, which are open upwards, in support walls on the covering plate. In the swivel direction (8), the sealing lever (3) reaches the open position (10) only after overcoming a dead centre position (9), up to which point the spring hinge (2) curves in the direction (x) until it subsequently assumes an unstressed position below the upper side (at 23a). A sturdy closure is thus provided which does not project beyond the closure edge after being opened and completely covers the mechanism so that the function of the spring hinge is not or is hardly recognisable.

Abstract: A double side band (DSB) demodulator compatible for a carrier suppressed amplitude-modulated signal and a carrier non-suppressed amplitude-modulated signal and a demodulating method therefor are provided. The inventive demodulator includes circuitry (2, 4, 5) for performing in-phase synchronous detection of an input modulated signal, circuitry (3, 4, 8, 10) for performing quadrature synchronous detection of the input modulated signal, a detector (11) for determining whether a signal obtained by demodulating the carrier non-suppressed amplitude-modulated signal is included in an in-phase synchronous detected output, and a selector responsive to an output of the detector for selectively passing one of the in-phase synchronous detected output and a quadrature synchronous detected output. According to this structure, even if signals obtained by quadrature modulation of the carrier suppressed amplitude-modulated signal and the carrier non-suppressed amplitude-modulated signal are inputted, a signal obtained by DSB demodulation of the carrier suppressed amplitude-modulated signal is always obtained in an output of the selector by switching a detection output depending on whether a demodulated component of the carrier non-suppressed amplitude-modulated signal is included in the in-phase synchronous detected output.

Abstract: The present specification discloses an oven foruse in the orientation and heat setting of synthetic yearns and filaments. One known oven comprises an elongate chamber (1) through which a filament to be processed is passed, hot gas being introduced intot he chamber (1) near to the region where the filament enters the chamber. The hot gas is introduced into the chamber (1) under pressure in the general direction of filament travel and thus heats the filament as it passes through the chamber (1). However there is a problem as the hot gas quickly reduces in temperature due to the heat absorption by the filament and also due to the expansion of the gas as it enters the chamber (1). Thus very little heating is found to take place after the filament has passed through the jets of hot gas on entry into the chamber (1). 
     The present invention provides an oven comprising an elongate chamber (1) with an inlet orifice (5) at one end and an outlet orifice (7) at the other end, via which a filament can pass through the chamber (1). Primary nozzles (15) for use in introducing hot gas into the chamber (1) are arranged, together with a gas outlet port (13), adjacent to the said one end (5) of the chamber (1). Preferably the outlet port (13) is nearer to the said one end (5) than the primary nozzles (15). Secondary nozzles (17) also for introd­ucing hot gas into the chamber (1) are arranged adjacent to the other end (7) of the chamber. In use, hot gas is fed under pressure into the chamber (1) via the primary and secondary nozzles (15,17) against the direction of filament travel. Whilst the hot gas   is fed under high pressure through the primary nozzles (15), the hot gas is fed at a relatively low pressure but high volume through the secondary nozzles (17). In this way the filament is heated all along its length in the chamber (1).

Abstract: A discharge arc lamp includes an arc tube (1) containing a dose, an electrode structure (4) sealed to each end of the arc tube, and an insert member (11; 23, 24) positioned between the arc tube wall and at least one said electrode structure(4). The insert member (11; 23, 24) is arranged to define a wick (12, 13, 15; 22, 22′; 25, 25′) which is effective, in operation of the lamp, to more liquid dose, by capillary action, from a relatively cold region (R₁) of the arc tube (1) adjacent to said end into a reservoir (R₂) in a relatively hot region of the arc tube (1), and to further define a passageway (16) allowing movement of dose, by vapour diffusion, to said relatively cold region (R₁). The wick (12, 13, 15; 22, 22′; 25, 25′) is so configured as to accommodate a variable volume of liquid dose. The passageway is configured to enable attainment of a desired operating pressure in the arc tube (1).
