Patent DE-2820825-A1 (DE)
Title: Single phase induction motor with two windings - with auxiliary winding divided into two branches in series with capacitor and resistor
Inventor: GHOSH SHYAMAL
IPC: H02P1/44
Filed: 1978-05-12
Abstract: The modified auxiliary winding circuit is intended to assist starting. The auxiliary winding is divided into two parallel branches (3, 4). One branch is in series with a capacitor (6), the other with a positive temp. coefficient resistor (5). At starting, the PTC resistor (5) has a low value and the current flows through both auxiliary coils to give a high starting torque. As the PTC resistor heats up, its resistance rises to a high value and effectively switches off the winding (3) in series with it. The motor then runs on the main (2) and capacitor-linked auxiliary winding.

Title: Slow speed external rotor synchronous motor - with short circuited windings on auxiliary poles for starting
Inventor: MERKLE PAUL
IPC: H02K19/06
Filed: 1978-11-03
Abstract: The internal stator has two diametrically opposite limbs (6) which are divided into a main (f, h) and auxiliary pole (o, q). Each complete limb is surrounded by a winding (7, 8) and the auxiliary poles each have a short circuited winding (9, 10). At right angles to these poles are further main pole limbs (p, n) which end in pole tips (i, k, l) having the same spacing as the rotor poles (m). The damping windings (9, 10) on the auxiliary poles (o, q) serve to cancel torques acting in opposition to the preferred direction of rotation, and thus assist in a quicker run up. The starting process is analogous to the run up of a single phase shaded pole motor. During synchronous operation some small torque contribution is still provided by the starting poles.

Title: Mixing device for diluted solution preparation - with extra weight in concentrate bladder riser
Inventor: WIENHOLD WILLY
IPC: B01J4/02
Filed: 1979-03-24
Abstract: The Parent Patent described in a device for the preparation of diluted chemical solutions by feed proportioning of a liquid concentrate to a fluid in a pipe. In this addn the concentrate is contained in a bladder inside a container. A riser inside the bladder allows the concentrate to be raised for admixture to the fluid by the fluid pressure exerted on the bladder outside. The riser contains an additional weight which rests on a cut-off disc. The latter operates a valve which gives access for the fluid in the container to another outside riser in the container. The extra weight ensures that the access to the outside riser is kept locked as long as any concentrate is left in the bladder.
