    摘要: An automatic visual music teaching device for displaying the structure of coded chords. The device comprises a plurality of actuable switches for selecting a desired coded chord. Signals associated with the actuated switches are temporarily stored and are indicative of the desired coded chord to be visually displayed. A further switch is activated to transfer the stored signals indicative of the desired coded chord to a decoding circuit. The decoded circuit feeds a memory system to select in a matrix the composite parts of the desired coded chord in accordance with a coded data signal sent to it by the decoder whereby the composite parts of the desired coded chord are visually indicated on a visual display element. The method of visually teaching the component part structure of musical coded chords comprises simply the step of selecting switches having coded marking thereon representative of musical notes in major and minor tones and corresponding to a desired coded chord for transferring a corresponding signal to a temporary storage circuit. A transfer switch is then depressed to obtain the visual indication of the composite parts of the desired coded chord for learning purposes.

    摘要: Electrical energy is produced from solid fuels in an ACFBC steam generator with two gas turbines and a steam turbine. The fuel is pyrolyzed in a fluid pyrolysis bed (34) with a hot partial flow of the bed material from the ACFBC steam generator (30), which together with the formed pyro coke is returned to the generator (30) as a fuel. The formed pyro gas (35) is combusted in one of said gas turbines (10), the exhaust gas (16) from which is used for steam generation (17). The other gas turbine (20) is operated with compressed air from its high pressure compressor (22) partially heated in a heat exchanger (51) in a fluid bed (50) with a controlled partial flow of hot bed material from said generator (30). The compressed air is finally heated by burning (24) fuel directly therein, and the exhaust gas from the power turbine part (22) is used as combustion air in the generator (30) which produces super heated high pressure steam for the steam turbine (40).

    摘要: An angle indicating device is provided for measuring the angle of an X-ray machine and to display the angle on the photographic plate at the time it is exposed to X-rays. The invention includes the combination of a pendulum mounted to maintain a vertical orientation during rotation of the X-ray machine about its horizontal axis, and an indicator for indicating the angle of the X-ray machine relative to a vertical orientation of the pendulum. Furthermore, a scale and a scale indicator, both of which are opaque to X-rays is provided to project the read out of the angle indicator upon the photographic plate.

    摘要: A device for the indirect heating of air or another gas at high pressure to a high temperature, consisting of a heat exchanger of a special construction submerged in a fluid bed of the "classical type", through which flows a fluidized hot, finely powdered bed material which is introduced (2) below the bed surface (3) and discharged through an overflow (5). The heat exchanger surface is formed by hairpin-shaped tubes (6) with legs of unequal length, the shorter legs thereof discharging into the upper bottom of an inlet chamber (7) and the longer legs thereof extending down through a tubular lead-through (9) between the bottoms of said inlet chamber (7), which lead-through is concentric with said tube leg and opens into the upper bottom of an outlet chamber (8), with an annular channel between said tube (6) and said lead-through (9). A bell (12) is secured to each of the long legs above the lead-through (9), forming together with the annular channel (11) a distribution means of "bubble cap" type for the fluidizing air supplied to the fluid bed (13). The low space (14) between the pressure chambers is separated from the fluid bed and is supplied with a small air flow, which through the annular channels (11) bubbles out below the "bells" (12) and fluidizes the bed (13). The invention is also related to the use of said device for the indirect heating of gas, especially air.

    摘要: Workpieces for producing a firearm have an elongated body defined within a cross-sectional profile with a first elongated passage configured to receive the upper portion of the bolt, and with a second elongated passage configured to receive the lower portion of the bolt, and the elongated body having a separator between the first elongated passage and the second elongated passage and configured to prevent installation of the bolt assembly when the separator is present, and to enable installation of the bolt assembly when the separator is absent. The cross-sectional profile may be along the entire length of the elongated body. The cross-sectional profile may fully encompass the first elongated passage. The first elongated passage may be open only at the ends of the elongated body. The cross-sectional profile may have a U-shaped cross-section.
