Title: Automatically controlled distillation of alcohol liquors - using condensate drop counter to measure and control distillation rate
Inventor: HENNING GERD F DR
IPC: B01D3/42
Filed: 1974-04-20
Abstract: Micro process for distilling alcoholic liquors such as wines, brandies etc. has rotating table to collect the various fractions and electric heating on the distillation vessel. The rate of boil up is measured by a counter which counts condensate droplets and controls the heating rate to the vessel. The measurement of the actual rate is determined by a photo-electric droplet counter connected to a controller which compares the signal to a set value and adjusts the boil up heater accordingly, dependent on the fraction being collected. The set value for each fraction can be individually set and when one is complete can be automatically changed with the rotation of the collection table, to alter the heating rate for the fraction following.

Title: Grill with rotary spit and grill tray holder - has locking means preventing contact between heating elements and rotating food
Inventor: APPEL WOLFGANG
IPC: A47J37/04
Filed: 1974-05-28
Abstract: The grill has an electric heating element and a drive with a rotary spit motor and gearing mechanism and is used for continuous rotary spit grilling and for intermittent rotary grilling and turning with a flat tray for steaks, toasted sandwiches etc. So that during spit grilling the heating element cannot contact the food, the parts of the rotary spit and tray support which interact with the drive means are made different and the rotary spit when fitted into the drive hub of the drive means forms a part of the locking mechanism which prevents the spit nearing the heating element. The distance between the heating element and the food can only be narrowed when the flat grill tray holder is inserted in the drive hub of the drive means.

Patent DE-2548790-A1 (DE)
Title: Universal type burner for town gas - has gas meeting air supply between pair of perforated plates
Inventor: RAWE RUDOLF DIPL ING
IPC: F23D14/20
Filed: 1975-10-31
Abstract: Gas is fed to a burner through a pipe placed co-axially inside another, which conveys the air supply. The gas flow is much faster than the flame velocity, and must be reduced at the burner to give a quiet region to feed a stable flame. This is done by placing a disc across the gas pipe. However, for a stable flame, natural gas must be fed into the air supply upstream of the disc, but coal gas (containing hydrogen) downstream, if the frame is not to run back up the supply pipe. By placing a disc across the gas supply and a pair of perforated plates (1, 2) across the air supply, the gas is fed lateral into the space between the plates, through openings in the collar (4) that separate them.
