Title: Optical telephone signal indicating system - controls isolating of earpiece during exchange signalling transmission
Inventor: KRAUSE ERWIN
IPC: H04M1/82
Filed: 1980-04-18
Abstract: The circuit is used to suppress acoustic signalling tones and substitute an equivalent optical display. The system is typically applied to a small switchboard, or instrument which is continually in use, and where constantly recurring acoustic signals would be unpleasant for the user. An incoming signal from the telephone line (2) is applied to an evaluator (1) and to the acoustic generator (3) via a switch (4). If the evaluator (1) detects a tone signal it commands (13) the switch to open and switch off the acoustic generator or earpiece. The tones are then further evaluated into, for example, calling tone, dialling tone, line engaged, line free, and used to switch on the appropriate signal lamp (9-12) in a signalling unit (8). The circuit can be added with relatively little difficulty to an existing installation.

Title: Pastry production process - in crust forming stage separated by deep freeze storage from final baking stage
Inventor: SUNDERMANN ERICH
IPC: A21D13/00
Filed: 1980-08-12
Abstract: Pastry is produced from dough mouldings with a dia. of 6-40 mm (8-34mm) which are exposed in perforated moulds to a vapour or gas heat carrier for a dough raising and form stabilisation stage in which a crust is formed by a first baking process. Such mouldings can be deep frozen and stored until required. They are then unfrozen and placed in a one- to three-layer distribution in perforated moulds where a second baking process with a gas heat carrier bakes them together to the desired shape. This saves time for the dough raising operation (up to 50%) and final baking and replaces the continuous raising-baking process by storing an intermediate prod. until required. It results in a tasty prod. with a greater proportion of crispy crust.
