    摘要: An apparatus and method for melt spinning polymeric yarns, wherein a main melt flow is generated by an extruder and supplied to a spin head. The spin head is enclosed in a heated spinning beam and comprises a mixer, a distributor pump and a plurality of spinnerets. A feed device generates a secondary flow which is supplied to the main melt flow for the purpose of additive admixture. The secondary flow and the main melt flow are combined inside the spinning beam.

    摘要: 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.

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.

    摘要: A yarn heating apparatus for use in a yarn false twisting machine, which has an axial channel in which the yarn advances along a zigzagged path. To guide the yarn in the axial channel, yarn guides are provided, which are shaped as spaced apart protuberances on two metal strips. The metal strips are supported in contact with the side walls of the axial channel.

    摘要: In the stuffing of synthetic continuous filamentary threads in stuffer boxes, special value is to be placed on the thermal treatment and especially the cooling of the initially crimped filaments. The filaments in the configuration of a compact thread plug, which is formed in the stuffer box, can be wound on a rotatably driven drum in several helical windings, the last thread plug winding can then be disentangled again at the end of the drum, and the finished texturized thread drawn off. The disentangling of the thread plug and the drawing off of the thread is improved by the present invention through an application of axial and/or radial forces or pressures onto the last thread plug winding in the region of the disentangling point. Suitable mechanical and pneumatic devices are provided by the invention for this purpose.

    摘要: The invention relates to a method for measuring the cooling curve of a test sample of metal or a metal alloy, in particular cast iron or cast steel, for the differential thermal analysis in which the difference of the cooling curve of the test sample of a fixedly given comparative curve which satisfies Newton's law of cooling (U=U.sub.0 .times.e.sup.-t/RC, the U.sub.0 parameter being the maximum value at the point in time t=0 and the RC parameter being the time constant) is formed, said comparative curve being brought to coincidence with a section of the cooling curve of the sample by adjusting its parameters so that the difference can then be formed between the adjusted comparative curve and the cooling curve.
