    • A cart for transporting and supporting electronic equipment such as musical instrument amplifiers includes a wheeled open frame which defines an amplifier-receiving space therein. The frame rotatably supports an amplifier support chassis so that the support chassis is pivotable about a pivot axis for varying the angular orientation of a piece of equipment supported on the support chassis. The support chassis includes inner and outer members telescopingly interconnected for adjusting the depth of the support chassis. A fulcrum bar rotatably supported by the frame is affixed to the support chassis for providing the pivotal capability to the support chassis. A locking mechanism is provided for fixing the support chassis in a selected orientation, and a restraint is attached to the frame for encircling and restraining a piece of equipment supported in the cart.
    • 用于运输和支持诸如乐器放大器的电子设备的推车包括在其中限定放大器容纳空间的轮式开放框架。 框架可旋转地支撑放大器支撑底盘,使得支撑底盘可围绕枢转轴线枢转,以改变支撑在支撑底盘上的一件设备的角度定向。 支撑底盘包括可伸缩地互连的内部和外部构件,用于调节支撑底盘的深度。 由框架可旋转地支撑的支杆被固定到支撑底盘上,以将枢转能力提供给支撑底盘。 提供了一种锁定机构,用于将支撑底盘固定在选定的方向上,并且约束件附接到框架,以围绕和限制支撑在推车中的一件设备。

    • Apparatus for the determination of bond forms of gases, such as a sample containing oxygen or nitrogen in solid or liquid small metal samples (e.g. from 0.8 to 1.2 g).The apparatus includes a furnace to heat the sample to a temperature of about 3000.degree. C. maximum in less than five minutes, a control device to control the rate at a value between 20.degree. C./sec and 350.degree. C./sec, a gas analyzer coupled to the furnace to indicate as a function of the supplied gas the quantities of gas released from the furnace in equal periods of time, and a computer coupled to the furnace and to the gas analyzer for receiving therefrom a measured value sequence in the form of a curve (Evologram) related to the gas quantities released per unit time to the computer for the determination of the bond forms of the gases contained in the sample, and the computer forms a first derivative curve and a second derivative curve from the measured value curve (Evologram) to form measured values between successive points in a minimum position and/or points which occur as a second inflection point immediately after a first inflection point on the measured value curve, these point positions being identified by zero indications and extreme positions on the derivative curves.
