Title: Sealing plug-in pipe-connection system
Inventor: MAYER HERBERT
IPC: F16L37/138
Filed: 1982-12-18
Abstract: The invention relates to a sealing plug-in pipe-connection system for liquid or gaseous media. It has the object of providing a firm and sealed pipe connection which can be plugged in and secured and cuts down on the mounting time, energy and auxiliary means. According to the invention, this is achieved in that the retaining and securing spring, which is fastened on the pipe by means of the ring, latched in the groove provided, and relieved, overlapping washer, connects said pipe to the joining part by its specially shaped spring ends latching in a captive manner into the depressions provided in the joining part. In each case, this ensures that the plug-in depth of the pipe end engages over the seal located in the joining part. If required, the latched-in spring ends can be arrested on the joining part by means of an additional securing means. The drawing shows an additionally arrested pipe connection. The advantages to be achieved consist in the rapid, firm and sealed pipe connection which can be secured and is capable of additionally relieving the fitter of any worries regarding risks relating to sealing or torsional freedom. <IMAGE>

Title: Device and arrangement for guiding belt-shaped webs of material
Inventor: KLEIN HERMANN ING GRAD
IPC: B65H23/02
Filed: 1983-03-11
Abstract: Method and device for the edge-aligned or centred guidance of belt-shaped webs of material which run over rollers and are guided by means of a correcting element which can be adjusted by means of a regulator, the web of material (1) being pneumatically scanned in the region close to its edges by means of a sensor (2, 2') comprising a transmitter nozzle and a receiver nozzle. The stream of air entering the receiver nozzle (4, 4') is guided into a pressure cell (6, 6') and transformed into an electrical signal in proportion to its pressure, from which electrical signal a signal for adjustment of the correcting element can be derived. Three regulating sequences can be selected by means of a selector switch (10), according to whether only one of the two belt edges are scanned, or whether both belt edges are scanned simultaneously for centred adjustment. The output of the pressure cell (6') is fed directly, and the output of the pressure cell (6) via an inverting operation amplifier (11), additively to the input of an operational amplifier (13). A power amplifier (14) whose output signal loads a motor used to drive a correcting element, for example, is inserted downstream of the operational amplifier (13). <IMAGE>

Title: Yarn-delivery device for yarn-consuming textile machines, especially circular knitting machines
Inventor: FECKER JOSEF
IPC: D04B15/48
Filed: 1983-05-07
Abstract: A yarn-delivery device for yarn-consuming textile machines, especially circular knitting machines, is equipped with at least one yarn-delivery roller which is preferably designed as a bar cage and is mounted freely rotatably on a holder about a fixed axis of rotation and round which a driven endless band is looped, over a predetermined circumferential region. Yarn-guide members, which are adjustable between two positions, in a first position introduce the yarn into the looping region between the band and the circumference of the yarn-delivery roller, whilst, in a second position, the yarn is held outside this region. In order to prevent impairment of or damage to the yarn lifted out of the looping region of the band and not transported, the arrangement is such that, in the second position of the yarn-guide members, the yarn loops round the yarn-delivery roller to a substantially lesser extent than in the first position, or the yarn is kept out of contact with the yarn-delivery roller.
