Abstract: An apparatus for applying a stratified charge to a reciprocating internal combustion engine is disclosed. The apparatus comprises a cylindrical rotary valve body disposed for rotation within the head of an internal combustion engine. The valve body defines first and second inlet ports and an exhaust port. The first inlet port is disposed, upon rotation in the valve body, to establish communication between an intake manifold for transporting a fuel lean charge and a main combustion chamber of the engine. The second inlet port is disposed for establishing simultaneous communication between a second manifold for transporting a fuel-rich charge and a pre-combustion chamber adjacent the main combustion chamber. The exhaust valve is disposed for establishing communication between an exhaust manifold and the main combustion chamber. In a second embodiment of the invention, the inlet passages and the exhaust passages are located in separate valve bodies mounted for rotation within the head. Means are also provided for shielding the exhaust passages from excessive exhaust heat, for sealing the rotary valve body and for controlling the timing of the valve in response to engine demand.

Abstract: The primary of the ignition coil is tapped to provide two partial primary portions which are serially connected; during an initial current flow, only one partial portion has current flowing therethrough, the other partial portion being short-circuited. When the current through the coil has risen to a predetermined level, as sensed by current flow through a sensing resistor, the short circuit across the second partial portion is removed so that current can continue to flow through the entire primary, causing a substantial drop in current level but maintaining the stored inductive energy. Current can thus rise rapidly initially, so that the coil will store sufficient energy to initiate sparking at high speeds of the connected internal combustion engine while, at low speeds thereof, the overall current flow through the coil is decreased.

Abstract: A class-AB audio amplifier comprises, as a final stage, two complementary power transistors connected across a direct-current source in series with an output resistor whose junction with the first of these transistors is grounded through a capacitor. The bases of the power transistors are connected across a biasing resistance inserted between two complementary pilot transistors which are connected across the d-c source in series with a constant-current generator, one of these pilot transistors having its base connected to a signal input while the other forms part of a differential circuit also including a feedback transistor of the same conductivity type connected across the source in series with the constant-current generator. With the base of the last-mentioned pilot transistor held at a constant potential through a Zener diode and the base of the feedback transistor tied to the aforementioned junction, any change in the junction potential is compensated by a variation in the current flow through the biasing resistance modifying the conductivity of the first power transistor to keep its current substantially constant, that current flowing alternately into the second power transistor and into a capacitor connected across the latter transistor in series with a load.

Abstract: The subject of the invention is a continuous filtering-settling centrifuge designed for separating continuously mixtures containing solid and liquid bodies. In the centrifuge several filtering or settling baskets are applied, situated beyond the main axis of spinning, and rotating around their own axes at an angular velocity different from the angular velocity of the centrifuge. In the particular filtering or settling baskets there is applied a system of feeding the mixture to be centrifuged, constituting a separated feeding zone, and a discharge system constituting a separate discharge zone with a chute receiver or a worm receiver. Besides, in the particular baskets there are separated zones of centrifuging, washing the solid part with a liquid, steaming of the solid part, separating of the washing agent or steaming agent, drying of the solid part, and washing of filtering screens with appropriate technical means in the particular zones. In the baskets finned partitions are applied. The finned partitions prevent a displacement of the mixture along the circumferences of the baskets, thus preventing damaging of the centrifuged solid part and the filtering screens in case of the filtering centrifuge, and also enable to drain off liquid from the basket in case of the settling centrifuge.

Abstract: The method comprises spraying at higher loads a fuel jet (17) through an ignition chamber (9) and a connecting passage (10) onto the wall (18) of a combustion chamber (4), where it spreads as a thin film (19). The air flow in the ignition chamber (9) during the compression stroke of the piston (2) and control of fuel injection is such as to cause individual fuel particles to be separated from the fuel jet (17) to form an ignitable mixture with the air and residual gas remaining in the ignition chamber (9). This ignitable mixture is ignited in the ignition chamber (9) so that a flame penetrates through the connecting passage (10) into the combustion chamber (4) to ignite the fuel evaporating from the combustion chamber wall (18). At idling and lower loads the injector provides an atomised spray (20) and an igniter provides for starting. <IMAGE>

Abstract: An object is produced from a tubular blank (10,15,17) of thermoplastic material of polyester or polyamide, preferably of polyethylene terephthalate by reducing the thickness of amorphous material in one or several areas of the blank by means of one or several consecutive re-shaping operations. A mechanical shaping device (23,29,71,81) moves a transitional zone (13,14,113) situated between thicker and thinner material along the blank and simultaneously elongates the blank in the moving direction of the transitional zone while reducing the thickness. After the last re-shaping operation the thinner material preferably has an oriented state. During the re-shaping operation the temperature of the material in the transitional zone (13,14,113) is controlled at a level which, immediately before the re-shaping operation, is within or close to the range of the glass transition temperature (TG). In one embodiment the reduction of the wall thickness of the material is begun in a track (12) in the wall of the blank and continues symmetrically around the track. Clamping devices (41,51,61) are used to maintain the axial position of the blank. The blank is suitable for re-shaping, for instance, into a container in which the mouth also consists of oriented material.

Abstract: The state of a flowmeter used in an installation is determined and, where necessary, its function is corrected, partic. where the meter causes a pressure drop in the medium being handled. The flowmeter's characteristics, i.e. the relation between pressure drop and flow is determined prior to its installation. During operation the pressure drop over the meter is evaluated, and the provided flow is measured. The relationship thus established is compared with that determined prior to the meter's installation. If there is a discrepancy, the meter is corrected. A pipe conduit part (1) is used in which the flowmeter (2) is installed. On each side of the meter is a connecting component (4,5) for determining the pressure drop in the conduit (1).
