Title: Control device for textile machines
IPC: D03C1/14
Filed: 1989-09-19
Granted: 1993-02-24
Abstract: A control device (57) for textile machines, in particular dobbies, has two magnet yokes (1, 2) with associated permanent mgnets (3) and electromagnet (4), as well as an appropriately built magnet armature (5, 55) held in the first or second end position by the permanent magnetic flow. When a current control pulse is applied to the electromagnet (4), however, the armature suddenly moves to the opposite end position, where it is again held until the next current control pulse moves it to the other end position. Only a very short current pulse is necessary to make the magnet armature (5, 55) change position. The resulting energy impulse is very intense and allows the holding and switching mechanic elements of dobbies to be directly controlled.

As a glass-making apparatus the invention includes a cyclone melt reactor for forming a liquid glass melt and a combustion preheater for receiving the glass-making materials and combusting the fuel and oxidant therein to heat the glass batch materials to a temperature at least equal to the melt temperature of the glass batch material. The combustion preheater has an outlet connected to the glass melt reactor, and at least one inlet is provided into the combustion preheater for introducing oxidizing materials and for creating a well-stirred region within the combustion preheater means. Supplemental heat can be provided by introducing a heated transfer gas into the combustion preheater, and a fuel gasifier can be provided for producing a fuel gas before the fuel gas is injected into the combustion preheater. For processing materials under reducing conditions, the cyclone melt reactor is connected to a preheater/reducing chamber and preheated reducing gas is introudced into the reducing chamber in such a manner that a well-stirred region is created within the reducing chamber. Heated transfer gas from a supplemental heat source and reducing gas from a fuel gasifier can also be introduced into the reducing chamber.
