Abstract: In an internal-combustion engine, in order to be able to vary the control times for opening and closing the gas inlet and outlet valves, the camshaft controlling the valves is constructed of two assemblies moving with respect to one another. A first assembly, supported on the internal-combustion engine, consists of a hollow outer shaft (1) with a first half of the control cams (5), for only the gas inlet or outlet valves, fixed thereto. The second assembly is an inner shaft (3), supported concentrically in the outer shaft (1), on which is mounted the second half of the control cams (4) via pins (7) protruding through radial slots in the outer shaft (1). The control cams (4) connected fixedly to the inner shaft (3) are supported on the outer shaft (1) such that they can rotate. By means of an adjusting device (10) integrated into the drive wheel (gear wheel 13), the angular position between the two halves of the control cams (4, 5) can be continuously adjusted over a predetermined range. The adjusting device (10) may be operated hydraulically or by means of an electrical stepping motor. The control signals for the adjusting device (10) are derived from selected engine operating data and namely, in particular, the air induction flow rate. <IMAGE>

Abstract: The pile (30') to be separated is pushed with its corner (30c) at the front over a passage (4), which is bounded by two table tops (2, 3). Fastened to the end face (3a) of the one table top (3) is a separating strip (27) having a wedge-shaped cross-section and facing the direction of movement (E) of the pile (30'). During the movement of the pile (30') from the one table top (2) over the passage (4) to the other table top (3), the said separating strip (27) travels in between the layers of the pile and separates a bottom part (39) of the pile (30') from the part lying above. This separated part (39) of the pile is deflected downwards through the passage (4) and is collected as a packet in a collector arranged below the passage (4). After the pile (30') has been pushed completely beyond the passage (4) onto the second table top (3) the separated, lower part (39) of the pile can be removed effortlessly by hand from the collector and placed next to the remainder of the pile (30'). The lower end of the pile (30') can now be connected to the end of a following paper web to form an endless web. <IMAGE>

Abstract: An input signal (R on/off ) for controlling a television power supply has "power-on" and "power-off" signal states. When the input signal is in the "power-on" state, it couples a clock signal (CK) to a primary winding (W1) of a transformer (T3) causing an alternating current voltage (V W2 ) that is conductively isolated from the input signal to be developed across a secondary winding (W2) of the transformer (T3). When the input signal (R on/off ) is in the "power-off" state, it decouples the clock signal (CK) from the primary winding (W1) so that no alternating current voltage is developed across the secondary winding (W2). The signal across the secondary winding is demodulated in a demodulator (41) that produces a control signal (S hot ) that is conductively isolated from the input signal (R on/off ). The control signal (S hot ) is coupled to a regulator (38c) of the power supply (38). A power-on state of the control signal occurs when the alternating current voltage (V W2 ) is developed at the secondary winding terminal (W2a). A power-off state of the control signal occurs when the alternating current voltage (V W2 ) is absent.

Abstract: An improved image restoration technique for an MRI method is provided where after the corrected location of image points is determined, an improved interpolation technique is used in determining the intensity value of that image point utilizing the surrounding pixels, e.g., 4 or 16. The interpolation technique provides for a uniform noise variance by using a weighted average interpolation technique with the added constraint that the sum of the squares of the interpolation weighting functions is substantially equal to a constant. The resulting image may be sharpened by a hybrid convolution technique which separately processes border regions.

Abstract: Quick cooking rice products are manufac­tured in a low mechanical shear extrusion process by first pre-cooking a rice and water mixture in a preconditioner and then advancing the mixture along the length of an extruder sequentially presenting a cooking zone, a venting zone, a forming zone, and finally an extrusion die to yield an extruded prod­uct. Venting of gaseous products removes a signifi­cant amount of moisture from the mixture during the time that the latter passes between the cooking zone and the forming zone, and consequently the moisture content of the mixture within the cooking zone can be increased in order to reduce the total mechanical shear imposed on the mixture during the cooking process. The extruded product, once dried, closely resembles rice grain and readily rehydrates without exhibiting slimy or sticky characteristics, and has an increased tolerance to overcooking. A venting device has a rotatable screw for enabling gaseous materials to be discharged from the mixture while substantially preventing the escape of the mixture from the extruder barrel of the extruder.

Abstract: A process for the preparation of synthesis gas by partial combustion of finely divided solid carbon-containing fuel with an oxygen-containing gas in a reactor. The liquid slag formed during the partial combustion process falls into a water bath or slag quench vessel where it solidifies and from there falls by gravity into a lockhopper from which the solidified slag is batchwise sluiced out of the gasification system. A gas bubble or gascap is created and maintained in the lockhopper, the pressure of the gas bubble being lower than the pressure in the slag quench vessel. Thus an initial downwards flow of water and slag is created during opening of the valves between the lockhopper and the slag quench vessel.
