Title: Automated determination of sugar content - by compensating pH difference caused by acid converting bacteria
Inventor: POLLACH GUENTER DIPL ING DR
IPC: G01N33/14
Filed: 1974-04-02
Abstract: The content of saccharose, glucose and fructose in natural and processed products of the food industry (sugar beet press water) is determined by adding a certain sugar-contg. sample to a culture of microorganisms which convert sugar to acid and by measuring the pH-drop caused thereby. The sugar content is calculated from this record. Instead of the full pH-drop, the pH-difference caused by premature addition of an alkaline solution and/or lye is continuously compensated. The sugar content is determined by comparing the total lye consumption with a calibrated solution. This method is simple and requires little appts. It is suitable for a wide range of concentrations and is easily automated.
Patent DE-2430437-A1 (DE)
Title: Explosion-proof capacitor with inner and outer containers - has containers driven apart and supply disconnected by internal pressure increase
Inventor: NACHTIGALL EDUARD
IPC: H01G2/14
Filed: 1974-06-25
Abstract: The explosion-proof capacitor consists of two housing halves (1, 2) that engage one inside the other and are sealed at their junction. The housing halves are free to move axially relative to one another as the pressure inside the capacitor builds up. The both housing halves have each a fixed electric terminal (8) linked to a terminal (9) attached to the other housing half. When the two housing halves are forced apart by the inner pressure increase, the connectors are separated and disconnect the supply to the capacitor parts, thus stopping the condition causing the pressure increase and preventing an explosion. A rupturing fuse may be incorporated.

Title: Control device for small computer displays - combines control of oscillograph tube output and matrix printer
Inventor: BENYO ZOLTANNE
IPC: G06F3/153
Filed: 1975-04-24
Abstract: The system relates to the unified control of oscillograph displays and matrix printers for table-type computers. Picture spot formations for the video output are synchronised with the character formations for the printer. A counter unit is used in conjunction with pulsed signals to control the data output speeds of both the video and printed data output devices. Separate counting control devices are required to determine the spatial positioning of the characters to realign the data as the end of traverse position for the video display does not necessarily coincide with a similar situation arising in the line or column tabulation of the printer.
