Abstract: A dual circuit brake valve includes a plunger assembly (20) carrying the primary valve seat (48), and the primary valve poppet (44) within the primary piston (20). A pair of axially-spaced, circumferentially extending bearing members (24, 26) extend from the primary piston (20) slidably engaging larger and smaller diameter portions (l6, l8) of the bore (l4) of the housing (l2) to thereby guide the primary piston (20) independently of other components within the housing (l6). The secondary set of valve members (92, l00, l06) is actuated by a relay piston (76) which is similarly guided in larger (80) and smaller (72) diameters of the bore (l4) independently of other components within the valve housing (l2). The primary piston (20) defines a pressure effective area due to the difference in the larger and smaller portions (24. 26), so that inlet port pressure acting on the effective area yieldably urges the primary piston (20) toward the brake released position.

Abstract: @ A bleed flow modulator is used in conjunction with pressure regulating valves regulatng bleed air pressure from each engine to a common manifold. The bleed flow modulator monitors the pressure drop across a heat exchanger, which pressure drop is proportional to flow rate of bleed air through the heat exchanger. By providing a limited authority negative feedback single to the pressure regulating valve from the bleed flow modulator, flow rate of bleed air from each engine to the common manifold is kept near a desired uniform value, thereby achieving balanced flow extraction of bleed air from aircraft engines.

Abstract: The access method to the local area network allows transmission, on a unidirectional ring, or circuit-switched or packet-switched communications organized in hybrid frames, in which overlapping between the beginning of a frame and a residual of the preceding frame which is still to reach its destination is avoided without resorting to a rigid band allotment to the individual communications and to a network synchronization system, where a well defined node acts as a master clock. Also a local network using such access method is provided (Fig. 1).

Abstract: The present invention relates to a method for reducing the content of nitrogen oxide, especially nitrogen dioxide, in the effluent gases from an absorption column for manufacture of nitric acid and an apparatus for carrying out the method. The absorption in the upper 1-8 stages, preferably the upper 2-4 stages of the column, is carried out at a relation between the contact area in the liquid level for absorption on the plates and the free gas space for oxidation of 1,5-5, preferably of 2-3, larger than the corresponding relation for the horizontal plates further below. The relation between the contact area and free gas space is adjusted by increasing the overflow height for the liquid volume on the upper plates. Said relation can also be adjusted by reducing the distance between the upper plates. The apparatus comprises an absorp­tion column (1) having horizontal plates (6) with a liquid level (a,b) and oxidation spaces (9) between the plates (6). The overflow height on the 1-8 upper plates (6) in the column can be regulated to give a liquid level (a) 1,5-5 times the liquid level (b) on the plates (6) further below in the column, preferably (a) = (2-3).(b). The semispherical part (2) of the column (1) is separated from the upper oxidation volume (9) by a non-perforated plate (4). The two volumes (2,9) are in communicating via openings (10) between/in the plates (4). A pipe (3) through the semispherical part (2) can transport the effluent gases out of the column (1).

Abstract: Apparatus and method for compressing and de-compressing binary decision data by arithmetic coding and decoding wherein the estimated probability Qe of the less probable of the two decision events, or outcomes, adapts as decisions are successively encoded. To facilitate coding computations, an augend value A for the current number line interval is held to approximate one by renormalizing A whenever it becomes less than a prescribed minimum AMIN. When A is renormalized, the value of Qe is up-dated. The renormalization of A and up-dating of Qe are preferably based on a single-bit test. Also, each Qe value is preferably specified as a 12-bit value having the least significant bit set to 1 and having no more than four other bits set to 1. The number of Qe values in the 1/4 to 1/2 probability range is enhanced to improve coding efficiency. A decision coding parameter of preferably six bits indicates the sense of the more probable symbol (MPS) in one bit and identifies a corresponding Qe value with the remaining five bits. In addition to probability adaptation, the present invention discloses an allocation of bits in a code stream register in which preferably two spacer bits are inserted between a next byte portion (which contains a byte of data en route to a buffer) and a fractional portion which may be involved in further computation. With the two spacer bits, any code greater than or equal to Hex 'CO' which follows a Hex 'FF byte is illegal for data and therefore provides for an escape from the code stream. The two spacer bits also reduce the number of stuff bits inserted to account for carry or borrow propagation. Encoding and decoding can be performed interchangeably by hardware or software which feature differing coding conventions.

Abstract: A multi-gradation image signal obtained by multi-­gradationisation of a signal obtained by reading through a CCD (1) on original having a half tone is supplied to an unsharp signal producing part (5), which in turn outputs an unsharp signal (S U ) produced from the multi-gradation image signal and the multi-gradation image signal (S S ) itself. A comparator (12) discriminates a shadow portion of the original by comparing the multi-gradation image signal (S S ) with a reference value. As a result, a signal which is unsharp in the shadow portion of the original is produced from the multi-gradation image signal (S S ) and the unsharp signal (S U ).

Abstract: In processing especially washed coal mine refuse, the refuse being fractionated into various size fractions and separated off in a defined size fraction range, and the separated refuse being heat treated in an oven, processing of the coal mine refuse in an economical manner to give a hard or hardenable material having generally advantageous properties in construction technology, especially a high compressive strength and/or a high bending tensile strength, is achieved by comminuting the refuse after the fractionation but before the separation by surface pressure and by carrying out the heat treatment of the separated refuse in a temperature range from 750 K to 1100 K, especially from about 800 K to about 1000 K. Surprisingly, the resulting material has pozzolana-like properties and hence a high uniaxial compressive strength and corresponding bending tensile strength.

Abstract: Apparatus for measuring high temperatures in a boiler (10) transmits (20) pulses of acoustic waves from one side wall (22) of the boiler to an opposite side wall (24) thereof. Acoustic noise within the boiler, as well as the transmitted pulses of acoustic waves, are received (26) at the opposite side wall (24) of the boiler. The received signal is digitized (56) and compared to a digitized sample of the pulses during a time period which is more than the maximum transit time for the pulses between the side walls (22, 24). A point of maximum correlation between the sample and the signal is taken as the arrival time for the pulse and is used to calculate the transit time of the pulse across the boiler. This transit time is used in turn to calculate the velocity of the pulses. The temperature can then be calculated as a function of the velocity, the molecular weight of the medium and the specific heat ratio of the medium. Each pulse had a modulated frequency between 500 and 3000 Hz.
