Title: Method and device for manufacture of combined yarns from staple fibres
Inventor: SLAVOV GEORGI S
IPC: D01G19/04
Filed: 1987-01-19
Abstract: This method and device are employed in the textile industry. The combined yarns produced are very soft, furry, and bulky. The method uses staple fibers of different types, content and length, which are combed and mechanically separated from the wire clothing. Initially their front ends are picked, falsely twisted by means of individually and fully drawing the clothing, and bound together with a binding yarn. The device consists of a mechanism for the feeding of fibers in the form of a sliver (1) to a wire clothing roller (3), furnished with a mechanism for the separation of fibers (4) from the clothing with means for the addition of a false twist (5) to the separated fibers. There is additionally a hollow spindle (6) and a winding mechanism (8). The mechanism for fiber separation (4) is comprised of fiber separators (9) arranged along the combing roller (2) with two adjacent rows of needles between each. The fiber separators (9) have the capability to consecutively rise over the needles of the wire clothing (3) in the area of fiber separation (18). The means for the addition of the false twist (5) is represented by a spinning nozzle placed between the area of fiber separation (18) and the hollow spindle (6).

Abstract: ABSTRACT OF THE DISCLOSURE.      During start-up or run-on of a printing machine, a printed image is transferred from a printing cylinder (2, 24, 34) on a control or test cylinder (5, 26,35) which has a surface representative of the surface of a substrate (6, 25, 33) on which printing, later on, is to be effected, for example a white ceramic surface of roughness comparable to that of paper.  The image transferred on the control or test cylinder is optically tested while the cylinder rotates over a first partial circumferential range (7, 27, 36), and data derived, either by human observation or by electro-optical sensors (8, 28, 37) to permit readjustment of operating systems of the printing machine in accordance with desired operating parameters, such as register, inking density, ink/damping fluid relationship in offset processes or the like.  The printed  image is then erased, extinguished or removed, for example by cleaning, by a cleaning apparatus (13, 30, 39) located in a second subsequent range (12, 29, 38) of the circumference of the control or test cylinder.  Ink stripped off the control or test cylinder is recycled, and washing fluid ant ink are separated, for separate recycling. When appropriate printing is obtained on the control or test cylinder (5, 26, 35), substrates can then be passed through the printing machine and printing carried out without prior scrap test prints.  The method and system are suitable for all printing methods, but are preferably and primarily used in offset printing systems and methods.

Filed: 1991-09-06
Abstract: ABSTRACT OF THE DISCLOSURE    The  disclosure  relates  to  fast   amplification circuits that are designed to provide an output current of some amperes, proportional to an input voltage,  and have a frequency spectrum that  may go beyond 1 MHz.  A linear amplifier  follows the  fast variations in  the input voltage and gives a  load all the output  current so long as this current is  low. As soon as the  output current from  the  linear  amplifier  reaches  a  given value, a chopper amplifier gives a current that  causes a  reduction  in  the  output  current  of  the  linear amplifier. The circuit may  be applied, in  particular, to the  control  of  deflection coils  and  as  a  high efficiency amplification circuit for audiofrequencies.

Inventor: SHAW DAVID G
IPC: H04B1/62
Filed: 1991-11-21
Abstract: The problem of noise enhancement is eliminated in communications systems by predistorting the amplitude of the transmitted information signal in a manner which compensates for the amplitude distortion introduced in a portion ofthe communications channel. In the disclosed embodiments, the communications system includes two signal transceivers which communicate with one another through a communications channel. The communications channel includes two-wire subscriber loops adjacent to each signal transceiver with a four-wire transmission path disposed between the subscriber loops. Each transceiver transmits an information signal which, depending on the system noise characteristics, is predistorted to compensate for all or a portion of the amplitude distortion introduced in a subscriber loop adjacent to that signal transceiver. The predistortion necessary to provide such compensation is determined at each transceiver in response to received signals at that transceiver.

Abstract: Powder of not more than 1 µm in mean particle diameter is prepared to contain a mixture of superconducting phases mainly composed of 2212 phases of Bi-Sr-Ca-Cu or (Bi, Pb)-Sr-Ca-Cu and non-superconducting phases which is obtained by calcining and pulverizing raw material powder at least once, this powder is heat treated at a high temperature and thereafter coated with a metal to prepare a round wire by deformation processing, thereafter a tape type or flat type wire is prepared by deformation processing, then the wire is heat treated under conditions for allowing phase transformation of the 2212 phases of main superconducting phases to 2223 phases with facilitation of grain growth, thereafter the as-formed 2223 phases are highly densified by deformation processing or pressurization, and the wire is again heat treated so that the 2223 phases are strongly bonded with each other and the non-superconducting phases are finely dispersed.  Thus, a bismuth oxide superconducting wire having a high critical current density is obtained.
