Patent DE-2727184-A1 (DE)
Title: Embossing of designs onto soft copper sheets - uses cast iron plate with design cast in relief on surface
Inventor: BAUER GUENTER
IPC: B44C3/08
Filed: 1977-06-16
Abstract: A cast iron plate has a design or picture cast in relief on one surface. This design can be transferred to a sheet of suitable material such as soft copper by placing the sheet over the cast iron plate nad then hammering the sheet until the design is impressed on the undersurface of the sheet. The copper sheet can be made more rigid by turning over the edges of right angles all around the perimeter. Also insted of one massive cast iron plate the required design can be cast with a thinner plate which is then reinforced with a second plate.

Title: Twin screw plastics mixer - having degassing vent downstream of flow restricting zone
Inventor: TODD DAVID B
IPC: B29C48/92
Filed: 1978-07-27
Abstract: In a continuous plastics mixts. having twin interconnected cylinders with V-section saddle portions at the points of intersection of the cylinders, the rotatable shafts have radially adjacent pairs of cowiping elements, one element of each pair being in different cylinder and being of full bore shape, and the other element of each pair being of reducing size and axially staggered w.r.t. the other pair.

Title: Push-pull inverter - has separate output transformers for each load circuit comprising inductor
Inventor: GANZER ERICH DIPL ING
IPC: H02M3/338
Filed: 1979-06-13
Abstract: Galvanic separation of output circuits fed by the push-pull inverter permits unequal loading to be compensated at a low cost. The main transformer unit is made up of series-connected individual transformers (Tr1,Tr2) optimising the load circuits (L1,L2). The load circuit L1 includes the inductor Dr1 in series with the rectifier while a circuit L2 has a shunt capacitor C22. The inclusion of the inductors promotes maintenance of a constant current amplitude while the capacitor contributes to the equalisation of half-period cycles. Optimum operation of transformers is achieved by matching the load with a selection of the ratio of primary and secondary turns.
