Title: Multi layered dough portions for flaky pastry - by applying fluid fat mixt. to dough without full cover
Inventor: HAHN CARL-GEORG
IPC: A21C9/04
Filed: 1973-11-23
Abstract: The parent patent concerns the prodn. of dough portions for flaky pastry, in which the layers of dough are sprayed with a mixt. of fats in a fluid and chilled condition, and then folded together. The equipment makes possible the application of a uniform film of fat, the thickness of which can be adjusted accurately. In this patent, the layer of fat is applied only to sections of the surface of the moving sheet of dough, either as a continuous strip or band or intermittently, running lengthways, diagonally, zigzag or meandering, by >=1 pressure jet, possibly opened and closed alternately. The band of dough is moved at a constant speed through the application zone, the jets reciprocating transversely, or moving forward and backwards as well as sideways. As the layers of dough are not completely sepd. by a film of fat, but are in contact in places, involuntary movement relative to each other is ruled out. The enclosed fat vapourises during baking to form cavities between the layers, and make the pastry correspondingly lighter.

Title: Control circuit for triacs controlling motors braking - has oscillators triggering triac pairs when control exceeds reference levels
Inventor: JOHN REINHARD
IPC: H03K17/723
Filed: 1974-01-16
Abstract: The control circuit, for triacs or antiparallel thyristors controlling e.g. a motor braking windings, has an input trigger with two thresholds to generate two outputs depending on the control input level. The outputs start two oscillators whose outputs are rectified and applied over diodes to a common point. This common point is coupled over a resistor to the gate of the centre of three triacs. The gates of the two outer triacs are connected directly to the oscillator outputs. When one oscillator produces an output, the centre triac and one outer triac conduct so that the braking winding is excited.
