Abstract: The present invention relates to an aqueous alkaline developing solution comprising an alkaline mixture of an alkali metal silicate and/or an alkali metal metasilicate, wherein the M.sub.2 O/SiO.sub.2 molar ratio of said alkaline mixture is in the range of from 0.5 to 1.2, the total content of said alkaline mixture being in the range of from 6 to 15% by weight of the total developing solution, and wherein said developing solution comprises a non-ionic surfactant and at least another surfactant selected from the group consisting of anionic surfactants and amphoteric surfactants. An alkali metal hydroxide can be optionally added to the alkaline mixture. Also claimed is the concentrated developing solution to be diluted to the desired strength.

Abstract: A method for winding up a yarn reserve on a winding tube for a bobbin. The method comprises the steps of: continuously sucking the spun yarn, causing it to move through a circular yarn guide-positioning element, removably arranged coaxially with a yarn suction orifice; removing yarn positioning element from the suction orifice while the yarn being supplied and continuously passing therethrough; positioning said element above a yarn adherence zone of tube; breaking the yarn passing through the positioning element allowing the supplied yarn end to fall down on the tube adherence zone and into guide device, with yarn end facing externally of the tube end, and forming yarn reserve turns before winding the yarn bobbin.

Abstract: Device for yarn paraffining with solid paraffin in textile machines. The device comprises a block of paraffin carried by a support rotating on and sliding along a pin; a lever acting against the paraffin support and a return spring connected to the lever at a connection location angularly rearwardly displaced relative to the lever end acting on said paraffin support.

Abstract: An automatic positioning device for the control cams of the needle selecting cylinders on a circular knitting machine. According to the invention, the device comprises a portion fixed to the machine frame and a portion movable and rotating with the needle cylinder. The movable portion of the device comprises a cam support movable between extreme positions and cooperating with a retaining means operable by the fixed portion of the device to release, lock the cam and maintain it at predetermined positions between said extreme positions. On the other hand, the fixed portion of the device comprises a release member for said retaining means and cam positioning members, the cam release and positioning members being operated through linkages by a mechanical programming device.In known prior art devices such as U.S. Pat. No. 3,766,753, a control cam is disclosed which has several profiles. The cam is positioned in a vertical direction in order to bring a desired profile into alignment with a cam follower.

Abstract: A machine for inserting pins or pegs in the holes of needle selecting cylinders for circular knitting machines. According to the disclosure, the machine comprises a cylinder spindle and a side support movable longitudinally of the spindle, having placed thereon a device for inserting the pins in the holes of said cylinder; said device being controlled to sequentially operate by signals provided by a device for directly reading the pattern; a pin feeding means having a gravity storage means provides for feeding the pins in aligned relationship in front of a pusher member of said inserting device.
