Title: Coke oven charging gas purifier - with wide combustion chamber, conditioner and wet scrubber
Inventor: HOELTER HEINZ
IPC: C10B27/04
Filed: 1974-02-09
Abstract: Gases produced during the charging of coke ovens of the horizontal chamber type are extracted, burned and scrubbed by a carriage with an extractor tube contg. an ignition device. The tube diverges to a combustion chamber in which the gas velocity is less than 10 m/s. A conditioning chamber with water sprays is followed by a wet scrubber; steam nozzles produce the necessary motive power. This extends the residence time for the gases in the combustion chamber enough to ensure complete combustion. Tar, phenol and other substances producing any incrustation cannot enter the subsequent piping. The injected steam assists the precipitation of solid particles in the scrubber.

Title: Chill-cast aluminium alloy pistons mfr. - using directional solidification to obtain fine structure and high fatigue strength
Inventor: ANDERKO KURT DIPL ING DR
IPC: B22D27/04
Filed: 1974-05-24
Abstract: The parent patent described the prodn. of castings, esp. Al or Al-alloy pistons for internal combustion engines, using a round mould with an outer insulating jacket and a base-plate plus, if required, a core suspended in the mould. The melt solidifies from the base-plate due to indirect cooling and, after an adequate solid layer is formed, direct cooling is applied to the bottom of the casting. In the present invention, a limited, dosed amt. of molten metal at the correct temp. flows into the mould followed by heat-extn. at constant speed independent of the casting height so the temp. gradient in the solid layer near the junction with the molten metal remains constant. Provides directional solidification along the axis of the piston so a fine-grained structure is obtd. which, after heating for 5 hours at 230 degrees C gives an increased fatigue strength of 10.5-13 kp/mm2.

Title: Liquid trap in motor vehicle refrigeration circuit - made more effective by combining pressure regulator with trap
Inventor: SCHUMACHER ERNEST
IPC: F25B43/00
Filed: 1974-11-05
Abstract: Compressor-refrigerator cooling systems in motor vehicles are subject to failure, due to liquid coolant finding its way into the compressor, where it causes damage. Such failures commonly occur after the car has made a brief stop. It is usual to include a trap (2) in the connection between the evaporator and the compressor (1, 7) to hold this liquid and to serve the oil return circuit. The usual traps work adequately at low rates of flow, but produce too great a pressure drop at the highest rates, this difficulty is met by using a combined pressure regulator (10) and liquid trap.
