Title: Skewing of stator slots after winding - with subsequent location of the core by clamping or welding
Inventor: TRAUTWEIN GUENTER
IPC: H02K15/06
Filed: 1973-11-21
Abstract: The application is to the stators of asynchronous machines, particularly where automatic winding is employed. The core is assembled as a relatively loose packet of punchings with axial slots, and the coils places in position. Subsequently, using special purpose tools, the core is skewed by the required amount and locked, for example by axial pressure through a clamp ring or by a seam weld along the core back. The correct skew may be obtained by twisting the core further than required and allowing the elasticity in windings and core to spring it back by the necessary amount. This has the effect of minimising residual stresses in the windings.

Patent DE-2437781-A1 (DE)
Title: Plastic fibre mat sausage skin - stabilized by heated calendar rollers to fuse fibres with each other
IPC: A22C13/00
Filed: 1974-08-06
Abstract: The parent patent describes a synthetic skin for unsmoked sausages and Frankfurters made of plastic fibre material which has been processed to a spun fibre mat. To prevent the fibres from unravelling the material is stabilized by treating it with artificial resins or varnishes or dispersions. In this addn. the fibre mat is heated enough to fuse the fibres with each other without destroying the fibrous texture. During the softening or fusing phase, a mechanical treatment between heated calender rollers is applied, in which the roller press force is kept inversely proportional to the temp. This saves the use of additional resins etc. and results in a better prod. The tear resistance of the skin is higher and the fibres do not become unravelled when torn.

Title: Rapid starting static converter - particularly for standby supplies provides full power with minimum start up time and uses batteries for energy store
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H02M7/517
Filed: 1974-09-27
Abstract: The static converter circuit provides its full output power with a correct phase relationship to the supply which it will be replacing in a very short time. During normal supply periods energy is stored to be fed into the load system, and when priming or firing signals are allowed through to the inverter by interruption of the normal supply, the inverter is supplied by some standby d.c. source such as batteries providing both polarities. This ensures that the correct polarity is available at the instant of switching. Switching is by electromechanical relays, thyristors or triacs (Tr1, Tr2), the switching operation being synchronised from sensors in the switching network.

Title: Fruit stream peeler construction - with water bed for gentle charging and displacement tank attached to pressure vessel
Inventor: KUNZ PAUL
IPC: A23N7/00
Filed: 1975-04-15
Abstract: A steam peeler for potatoes, tomatoes, peaches, etc., consists of a pear-shaped pressure vessel with a filling chute and a dished bottom. It can be inclined and has a partial water bed at the bottom to cushion the impact during the filling operation. An overflow allows the displaced water to pass to a storage tank, attached to the bottom. When in the vertical position, an internal power cylinder closes the filler opening and steam is introduced through the pivot to peel the fruit. This makes the steam peeler suitable for more delicate fruit than potatoes without causing marks to the flesh of the fruit. The peeler tank volume can be smaller than with conventional steam peelers so that a pressure can be built up more quickly, again assisting the peeling of soft fruit.
