Patent DE-2448302-A1 (DE)
Title: Capacitor discharge system - for electronically regulated high tension ignition systems has sensing unit to determine capacitor charge
Inventor: DEINES KENT L
IPC: F02P3/08
Filed: 1974-10-10
Abstract: the circuit contains a voltage trigger switch an impulse producer and a sensing or charging indicator switch. The circuit receives its energy from the storage battery and builds up a charge in the ignition capacitor via the impulse generator. There is a zener diode in connection with a resistor which maintains a reference voltage which is fed to a trigger capacitor, which charges itself to the full zener diode tension. The sensor to determine the size of the charge consists of a voltage divider with resistors of a relatively high impedance, so that if the charge is low, current will flow from the trigger capacitor to the transistor base. The transistor forms with the transformer a blocking oscillator to give a tension in the third winding to regenerate a positive polarity on the transistor base.

Title: Formed coke prodn. - from brown coal briquettes in four-stage shaft retort with separate hot gas circuits
Inventor: LORENZ KURT DR
IPC: C10B53/08
Filed: 1975-02-22
Abstract: Abrasion-resistant formed coke is produced from brown coal briquettes which are preheated, dewatered or dried, carbonised and cooled in several (over three) stages. The gas in the hot gas circuits consists of the lean gas from the carbonisation operation, it circulates in each stage in a separate circuit, each with its own combustion chamber. This facilitates an adequate dedusting of the hot gases so that the condensation is not disturbed and clogging is eliminated. The coke mouldings retain their shape and are abrasion-resistant. An economical operation is ensured without mechanical partitions such as dampers.

Title: Compsn for determining urea in biological fluids - comprising urease, indicator dye and mixed buffers
Inventor: CHANG MICHAEL
IPC: C12Q1/58
Filed: 1976-01-05
Abstract: A new compsn. for determining urea level in biological fluids comprises urease, buffers and an indicator dye, the buffers being mixed and comprising >=1 buffer which increases in pH as the temp. increases and >=1 other buffer which decreases in pH with the temp. increase. The compsn. may also contain stabilisers. The urea level in urea-contg. fluids is determined by adding the above compsn. and measuring the absorbence of the soln. just after the urease has catalysed the total conversion of urea to ammonia. The method of determining urea is simpler and faster to perform than the previously known urease methods, it does not require elevated temps. for reaction, utilises harmless chemicals and is quantitative.

Title: Low temp. carbonisation oven - with heated rhomboidal refractory blocks for zigzag charge flow in thin layers
Inventor: GRAETZER GEORG
IPC: C10B1/04
Filed: 1976-01-09
Abstract: A low-temp. carbonisation oven contains rhomboidal refractory blocks, arranged across the vertical oven chamber. They are so arranged that the coal is forced to descend in a thin layer in a number of zigzag paths. The gas extn. tubes are arranged along the apices of the rhomboidal blocks. This prevents incrustations of the upper zones of the charge by the ascending low-temp. carbonisation gas. The flow of coal is heated extremely uniformly. The oven operates continuously and the charge is in constant motion which prevents clogging.
