Abstract: The invention relates to a control for a valve of an internal combustion engine. In order, for example, to increase the braking power of internal combustion engines, it is desirable to be able to vary the valve timing substantially independently of the movement brought about by the cam (2). For this purpose, the invention proposes to provide a connecting conduit (6) between the working piston (4) driven by the cam (2) and the reciprocating piston (8) of the valve (1), from which conduit there branches off a control conduit (17) leading to a control unit (18) which shuts off or opens the connection from the control conduit (6) to the return conduit (16) depending on whether the valve (1) is to open or close. The working piston (4) itself can function as a control piston and likewise shut off or open the connecting conduit (6) relative to the return conduit (16) in order to open or close the valve (1).

Abstract: A heating apparatus such as a microwave oven in which thermal energy of high-temperature vapor generated by heating an object (2) is detected by a pyroelectric element (5) and a resulting detection signal is used to control (stop) a heat source (3) such as a microwave source, etc. Among AC voltages generated by the pyroelectric element due to heat exchange of the pyroelectric element, a voltage of a polarity generated at the time of heat discharge (temperature decrease) of the pyroelectric element (5) is selectively eliminated through a circuit means (41). A voltage generated by heat exchange between air moving slowly in a heating chamber (1) and the pyroelectric element caused by the rotation of a turntable (33) or the like is eliminated by another circuit means (43). A control section (4) controls the operation of the heat source by deciding an output signal of the pyroelectric element by comparing it with a detection level determined in accordance with a noise level for a predetermined length of time after the start of the heating operation. Erroneous detection is thus prevented which otherwise might be caused by a noise voltage generated in the pyroeelctric element by the thermal energy of a hot air staying in the heating chamber after the energization of the heat source (3) or a second heat source (34, 35).

Abstract: The interlacing jet has a continuous yarn channel (3.1), into which open laterally an air feed bore (5) and a threading slit (4). The wall of the yarn channel (3.1) contains two cylindrical, for example circular-cylindrical wall portions, namely a baffle-wall portion (6.1) located opposite the air feed bore (5) and a nozzle-wall portion (9.1) adjacent to the air feed bore (5). The threading slit (4) opens out between the baffle-wall portion (6.1) and the nozzle-wall portion (9.1). The tangential plane (T) to the baffle-wall portion (6.1) at the edge (7) of the mouth of the threading slit (4) passes through the nozzle-wall portion (9.1). This ensures that the part of the airstream coming out of the air feed bore (5) and being deflected by the baffle-wall portion (6.1) towards the mouth edge (7) of the threading slit (4) and then leaving the baffle-wall portion (6.1) in the direction of the tangential plane (T) does not enter the threading slit (4). This reduces the danger of damage to filaments and filament bundles, since these are not blown into the threading slit (4). …<IMAGE>…

Abstract: A track circuit is disclosed, the receiver (E) of which carries out, for the purpose of track-release indication, a cross-correlation between a track voltage tapped off on the track (GL) and a reference voltage which is derived from the transmission signal of the track circuit transmitter (S) or generated separately. The maximum of the cross-correlation is sought by receiver (E) and compared with a predetermined threshold value. An embodiment with purely digital operation uses a track current source as transmitter which is controlled by a completely modulated transmission signal which is read out cyclically from a ROM. A microcomputer serves for calculating the cross-correlation function in the receiver (E) and for evaluating and tracking the maximum. The reference voltage is generated with the aid of a further ROM in the receiver (E) which is programmed in the same way as the transmission-side ROM. <IMAGE>
