Title: Open=end spinning of slub yarns - using flexible wire as obstruction in the fibre transfer tube
Inventor: ROHRBERG MARTIN DIPL ING DR IN
IPC: D02G3/34
Filed: 1978-02-28
Abstract: Prodn. of slub yarns on an open-end spinning machine is claimed in which the stream of fibres in the transfer tube is obstructed in an intermittent manner in order to produce a yarn with an irregular cross-section. The obstruction is pref. in the form of a thin wire of metal or plastic material protruding into the fibre transfer air stream at right angles to the direction of flow around which a proportion of the fibres become entangled, to be automatically released by the bending or rotation of the wire against the restraining influence of a spring, which may be the intrinsic elasticity of the wire itself, when the wad of fibres has reached a critical size. Method allows the high prodn. rate of the open-end spinning process to be applied to the formation of fancy yarns.
Patent DE-2811882-A1 (DE)
Inventor: DAMMANN PETER DIPL ING
IPC: D01H4/16
Filed: 1978-03-18
Abstract: The open-end spinning apparatus consists of two screen rollers (1, 2 concealed) which are arranged relative to one another in such a way that a narrow air gap is formed between their perforated air-permeable casings. These screen rollers are assigned an opening-roller unit (8) which consists of an opening roller (12), for opening a fibre sliver (spinning tow 10) into a cloud of individual fibres, and of drawing-in rollers (11, 42, 43), for drawing the spinning tow into the opening-roller unit (8). By means of a fibre-guide channel (16), the individual fibres (15) are guided from the opening-roller unit (8) into the very narrow gap between the two screen rollers (1, 2). In the fibre-guide channel, an air stream is generated by suction devices (21) arranged inside the screen rollers (1, 2). As a result of the arrangement of nozzle channels (50) in the side walls of the fibre-guide channel (16), transversely directed speed components and turbulences are imparted to the air flow guided in it. Helical air vortices can thereby be generated in the fibre-guide channel, especially in the direction of rotation of the thread produced or opposite to the direction of rotation of the screen rollers. The nozzle channels (50) open out in the first third of the fibre-guide channel (16) between the opening roller (12) and the mouth of the fibre-guide channel (16). <IMAGE>

Title: Calculator indicating instantaneous revolutions - uses analogue current varying between zero and 20 milliamps. depending on position of decimal point of result stored in 4 digit memory
Inventor: STOCK HEINZ
IPC: G01P3/44
Filed: 1978-08-16
Abstract: A calculator indicates the instantaneous revolutions using a load-independent analogue current output. The strength of the current varies from 020 mA. This analogue current is completely linear and a controlling tachogenerator is no longer necessary. The result from the calculator is stored in a four digit memory and converted by means of a d-a converter into a corresponding current. Circuit connections decide on the validity of the conversion. If, for instance, a speed of 10 to 99.99 r.p.m. is necessary for the control the connections are formed so that the decimal point signal after the second place of the result releases the control. If the decimal point signal appears after the first place, the analogue current increases to 20 mA. If it appears after the third place, the current sinks to OmA.
