Title: Automatic regulator for supply voltage - comprises air gap choke with controlled auxiliary winding
Inventor: MEINTRUP WALTER DIPL ING
IPC: G05F1/30
Filed: 1979-01-23
Abstract: A regulator finds application in the provision of constant voltage power supplies in, e.g. mining and quarrying works. In series with the output of a step down transformer (1) is an air gap choke (2) with separate main (3) and auxiliary (4) windings. The auxiliary winding is connected across an anti-parallel thyristor assembly (5, 6). Triggering of the thyristors is controlled by a regulator (7) which compares the voltage on the load side of the choke (Uist) with a reference voltage (U) representing the desired voltage for the suppl system. The regulator is fast acting and can compensate for the effects of large and sudden variations of load current. All power components can be contained within the step down transformer tank. Typical large units have an output of 2OMVA at 6kV secondary and 220kV primary voltage.

Title: Applying liq. treatment agents to textiles - using soft rubber padding rollers
Inventor: COTTON JAMES FRANK
IPC: D06B1/14
Filed: 1979-06-02
Abstract: In a process for applying treatment liqs. to textiles, the textile is passed between two soft rubber rollers which are pressed together such that one of the rollers, which is driven, causes rotation of the other roller. The liq. treatment agent is then applied to one or both rollers for application to the textile. The process allows the application of small amts. of liq. treatment agents such as dyes, fabric resin finishes, etc. to textile fabrics and gives excellent penetration of the agent into the fabric which is normally associated with padding treatments. Due to the small amts. of treatment agent used, the energy requirements for the process are very much lower than in normal padding treatments. Good control over the penetration of the agent into the fabric is possible by varying the pressure on the rollers, thus allowing a large number of interesting effects to be obtd.
