Title: Retaining freshness of bologna sausage in store - by handling and mixing ingredients so that the mass remains sufficiently coherent without becoming completely compacted
Inventor: HARTNER FRITZ
IPC: A23L13/60

Patent DE-2310941-A1 (DE)
Title: Impregnating tungsten cathodes with emission-promoting cpds. - esp. barium oxide opt. with other metal oxides, introduced as carbonates
Inventor: HOFMANN HORST
IPC: H01J1/28
Filed: 1973-03-05
Abstract: Porous W cathodes for electron-emission tubes and gas-discharge lamps are impregnated by depositing on a thin W substrate, BaCO3 or Ba and Ca carbonate mixt. and Al(OH)3 in the presence of NH4+ions, which enter the carbonate crystalline lattice and subsequently prevent the slight, but harmful, oxidation of W by CO2 or H2O during the thermal decompn. of the carbonate deposit. The vilatilisation of the oxidic contaminations is effected at 1000 degrees C; the rapid temp. rise (to 1750 degrees C) is stopped at 1000 degrees C for 15 mins.; a similar stoppage is applied during the cooling stage. By this method, oxidation of W, strongly reducing the emission, is eliminated in simple manner.

Title: Coke quenching hall fume extraction - by air curtain from quenching car towards inclined roof
Inventor: HOELTER HEINZ
IPC: C10B33/00
Filed: 1973-05-10
Abstract: A covered coke quenching hall on the discharge end of a coke oven battery of the horizontal chamber type has a roof which rises away from the oven doors. There is no vertical end wall and the coke quenching fumes are directed towards the extraction slots in the roof by an air curtain, created by nozzles mounted on top of the coke quenching car. This ensures that the operators are not exposed to toxic fumes even if some of the extractor fans in the roof should break down. The powerful draught ensures a reliable extraction of all developed coke quenching fumes.

Title: Safety circuit for motor vehicle additional heater - has flame monitor and a circuit for modifying charging of a capacitor
Inventor: HETZEL FRIEDRICH
IPC: H03K17/28
Filed: 1974-02-16
Abstract: The safety circuit for an additional heater is a motor vehicle has an RC circuit and a load side transistorised amplifier circuit. When the heater is switched on and in the case of absence of flame, or in the case of flame failure, it produces a delayed switching off signal. The response time varies automatically with the given fault and the delay is long for the absence of the flame on starting, and in the case of flame failure during operation the response time is short. The charging circuit has a transistor stage actuated by a low ohmic heating plug, and this system reduces the charging resistances of the capacitor.

Title: Simplified anti-blocking braking control - with brakes of non blocking axle isolated when control operates
Inventor: MOEDEKER OTTO
IPC: B60T8/34
Filed: 1974-06-08
Abstract: A simplified anti-blocking brake control is obtained by a separate control system for each axle. This reduces the number of interdependent variables to a minimum. In order to prevent extra braking pressure from being passed to the other, non-blocking axle, when the first axle brake pressures are modulated, a special set of isolating valves are fitted. These isolate the non-blocking brakes from the master brake cylinder, but do not vent these brakes. The brake pressure thus remains constant. The front wheels (1, 2) are each fitted with rotation sensors (11, 12), with the shut off valve (15) in the rear wheel (3, 4) brake supply line.
