Patent DE-2019486-A1 (DE)
Title: Conditioning of dough for pastry making
Inventor: SCHIFFMANN ROBERT
IPC: A21D6/00
Filed: 1970-04-22
Abstract: Pastry products such as dough-nuts are manufactured by kneading a suitable dough, containing yeast at ambient temperature to bring the gluten to the optimum edible state. The dough is extruded from a deivce which can move backwards and forwards across an endless belt which advances so that regularly spaced pieces of dough are deposited on the belt. The latter takes the pieces of dough through zones heated by a high frequency electric field. The pieces of dough, which have risen rapidly during the space of 25-360 sec, are then conveyed to the frying apparatus. The finished products have smooth, golden crusts with a white, collar cellular internal structure.
Patent DE-2029420-A1 (DE)
Title: Inductor for electric ovens with channels - for melting iron and non ferrour metals
IPC: H05B6/20
Filed: 1970-06-10
Abstract: The easily replaceable inductor, is shaped at its connection zone opposite the oven's boiler so that it forms a peripheral groove that is sealed with a suitable flame-proof material. The material completely fills the entire interior of the inductor body, and it is shaped onits side facing the connection zone so that a projecting stage is formed over the entire intermediate region of the connection zone. Thus, when the inductor is precisely mounted and bolted opposite the boiler, a peripheral groove is formed to encompass the entire circumference of the connection zone.

Title: Transformer with strip wound very low voltage output - uses subdivided cores and windings to attain correct ratio
Inventor: MUELLER WALTER DR
IPC: H01F27/28
Filed: 1974-05-24
Abstract: To bring the iron to copper relationship nearer to the optimum value in transformers with low voltage high current secondary windings. It is a number of turns, n, is used which is not a whole number, such that n = a + b/c where a is an integer and b/c a proper fraction. To realise the relationship the core is subdivided and wound with series parallel connected turns.

Title: Plastics waste disintegrator batch operating cycle control - by the temp. and power demand of disintegrator motor
Inventor: BRIXEL BERTHOLD
IPC: B29B17/04
Filed: 1974-07-09
Abstract: A batch disintegrator for waste plastics, where the matl. is fed into a disintegrator vessel contg. a rotor with beater arms, opt. simultaneously washed, heated solely by the energy of beating and disintegration, is agglomerated, compacted, cooled by spraying in liq. and then finally extracted from the vessel, is operated by regulating the commencement of the cooling stage not only by the temp. of the matl. in the vessel but also by the current demand of the electric motor driving the beater arms. Pref., the temp, of the vapour of the cooling liq. is utilised as a control parameter for the discharge stage. Since both the quantity and the type of matl. esp. its fusion temp., can vary considerably, it is possible with the conventional method where only the temp. of the batch is used as control parameter for commencing the cooling stage, that either too much cooling liq. is introduced due to the high heat content of the batch, or where the batch is very small, the contained heat is not sufficient to evaporate the cooling liq. completely. The use of the additional parameters as above improves the course of the process and results in an improved end product.
Patent DE-2434757-A1 (DE)
Title: Large capacity refuse container with sliding cover - has cover locking devices positively engaging with walls when shut
Inventor: STACHOWSKI JOACHIM
IPC: B65F1/16
Filed: 1974-07-19
Abstract: The container is particularly for refuse, and has locking devices (3) on the cover (1), working in conjunction with holding devices (4) on the walls (5). The cover positively engages in the latter in the shut position, and thus forms a cross-member for the rear opening in the container (1). The locking devices can be in the form of springs, engaging in grooves (6) in the holding devices inclined on one side. Thus they exert a tension load on the container walls. The design avoids the cover being affected by the tendency of the container walls to spread apart under load, while not affecting the loading operation.
