Abstract: 1. An arrangement for the electrode regulation of an arc furnace which is fed from a transformer and has an impedance regulator for each electrode, which controls the assigned setting element for the level adjustment of the electrode or of each of the electrodes in rotary-current arc furnaces, having a measuring element for supplying a magnitude proportional to the electrode voltage (U) measured between the secondary connecting terminal of the transformer and the furnace case and for supplying a magnitude proportional to the electrode current (I), where the operating points of predetermined characteristics of the furnace operation respectively assigned to a voltage stage of the furnace transformer can be stored as a theoretical impedance value (z*) in the cells of a digital store (1) provided for each electrode, where the theoretical impedance value (z*) of the respectively selected cell, which permanently occurs at the output of the store, is fed to the pulse regulator by a digital-to-analogue converter (8) and the voltage stage of the furnace transformer or the number of the characteristics and the assigned theoretical impedance values can be fed into the storage cells of the digital store (1) by means of numerical adjuster (2 or 3, 5, 6), characterised in that change-over switches (S2, S3) are provided which in their one position feed freely selectable magnitudes for the electrode voltage and the electrode current to a divider (7), and in their other position feed magnitudes which are proportional to the actual values of electrode voltage and electrode current to said divider, and the divider (7) determines theoretical impedance values (z*) from these magnitudes which can be fed to the store (1) as digital magnitudes and which can be alternatively input into the store in place of the stored theoretical impedance value with the aid of a further switch (T4), and that in order to correct the theoretical analogue impedance value (z*) predetermined in this manner a correction element (22) is provided which can be connected and disconnected by means of a change-over switch (S4) which can be manually operated.

Title: Process and system for dry scrubbing of flue gas
Inventor: BAKKE EVEN
IPC: C01B17/00
Filed: 1981-12-03
Granted: 1986-12-11
Abstract: A flue gas dry scrubbing process and system achieves higher sulfur dioxide removal efficiency with a better utilization of alkali reagent chemicals as well as increased dry product recovery performance using a combination of spray drying with an alkali reagent slurry and with a recycled stream comprising a mixture of unreacted alkali, sulfite and sulfate reaction products and flyash which directly contacts the sulfur dioxide-containing flue gas. Preferably the recycled mixture contacts the flue gas in the spray dryer (12). The invention utilizes a splitting method and a splitter apparatus (78) wherein the particle product powder is separated into two fractions for recycling (18) and for product disposal (82). The rate of splitting is fully adjustable over a wide range.

Title: A rebound stop member for a telescopic hydraulic shock absorber
Inventor: MOURRAY JACK
IPC: F16F9/58
Filed: 1982-09-20
Granted: 1988-12-08
Abstract: A rebound stop assembly (22) rests on a shoulder (30) fixed to a piston rod (16). The stop includes an elastomer ring (24) interposed between two collars (26,28) to form an annular chamber (74). At the end of the piston rod rebound stroke, the stop is axially compressed between the piston rod shoulder and the guide until the ring abuts the inner wall of the cylinder as it deforms. A restrictive passage allows some fluid flow to an additional chamber. Further compression of the stop decreases the volume of both chambers and causes restrictive fluid flow out through the passage into the lower section (68) of the rebound chamber. The ring compression and the restricted fluid flow provides additional damping at the end of the stroke.

Title: Improvements to apparatus for decoding error-correcting codes
Inventor: GORDON JOHN ASHLEY
IPC: H03M13/23
Filed: 1984-05-23
Granted: 1987-05-07
Abstract: An improvement to a Viterbi-type decoder for decoding convolutional error-correcting codes whereby decisions regarding which predecessor state to a given state most probably corresponds to the best path terminating in that given state are stored in association with that given state and not in association with the best path. Paths are reconstructed by searching through such stored decisions. Such searches are used to recover a number, possibly greater than one of data symbols for later output from the decoder. The larger this number, the less frequently a search need be carried out.

Title: Batch mixer
Inventor: MATHIS PAUL
IPC: B01F7/02
Filed: 1984-10-04
Granted: 1987-06-11
Abstract: Apparatus for mixing charges of flowable solid materials has a hollow cylindrical housing with two upright end walls and a hollow shell between the end walls. The lower part of the shell has a large material evacuating opening sealable by two mirror symmetrical doors which are pivotable about horizontal axes. The opening extends all the way between the end walls and is large enough to allow for gravitational outflow of the entire contents of the housing irrespective of the angle of repose of the charge. The doors are bounded by edge faces which make oblique angles with their external surfaces and abut against complementary edge faces of the end walls and shell. Sealing strips on the shell and end walls are engaged by deforming members at the external surfaces of the doors when the opening is closed. The abutting edge faces of the doors also make oblique angles with the respective external surfaces.

Abstract: A stereophonic broadcasting system incorporating companding of the difference signal in which both the usual difference signal(s) and a compressed version of te difference signal(s') are transmitted to one or more remote receivers (70). At the receiver (70) the usual difference signal(s) and the compressed difference signal(s') are combined (84) and the resulting signal then expanded (86) to obtain a noise-reduced difference signal for dematrixing (74) with the sum signal (M) to obtain the original left (L) and right (R) signals. Utilizing both difference signals increases the effective level of the received difference signal by about 6dB, whereas the noise is increased only about 3dB, for a net improvement of about 3dB in signal-to-noise ratio, and also permits compression of the difference signal according to any desired compression law and the use of the unchanged difference signal(s) as a reference signal for controlling the expansion (146) of the compressed difference signal(s') so as to cause the amplitude of the companded difference signal to equal the level of the usual difference signal(s). That is, the expander is adaptive to any compression characteristic that might be employed at the transmitter (24). Further the availability of the usual uncompressed difference signal(s) at the receiver enables the adaptive decoding of dynamic parameters of the received signal, such as frequency response and attack and recovery times, so that all of the parameters of the original signal can be restored automatically.
