Title: Girder mfr. by stamping from steel strip - followed by heat treatment to restore ductility to its required value
Inventor: HUFNAGL WALTER DIPL ING
IPC: C21D9/52
Filed: 1977-03-09
Abstract: Strip girders are made from steel strip contg. min. 0.02% carbon. The strip is stamped continuously or stepwise in a known way, e.g. in ints middle zone, to form an upper flange, whereas the sides are slotted and drawn out, possibly with further processing operations. The girders are then cut to length and heat treated by (a) 0.33-2.5 hours at 250-350 degrees C.; or (b) 0.17-2 hours at o50-450 degrees C. Heat treatment (a) may consist of specific times at the successive temps. 250 degrees; 300 degrees; and 350 degrees C. Treatment (b) may consist of specific times at the successive temps. 350 degrees; 400 degrees; and 450 degrees C. Alternatively, the treatment may consist of specific times at the decreasing temps. (a) 350 degrees; 300 degrees; 250 degrees C.; or (b) 450 degrees; 400 degrees; 350 degrees C. A further alternative is the use of a constant heat treatment temp. for a constant time. To obtain a desired combination of yield point, tensile strength, and ductility in the flanges and webs of the girders. The heat treatment may include a temp. equalisation process; and/or a protective gas can be used during any of the heat treatments mentioned. A hot bath or an air-circulation furnace is pref. used for cooling. The mfr. of the girder involves stamping, possibly followed by bending, pressing, straightening and deburring. The various cold working operations increase the strength but reduce the ductility, i.e. the elongation; heat treatments (a,b) provide stress relief, restoring the elongation to the desired value.

Title: IC engine catalytic converter unit - producing gaseous fuel from unusable liq. hydrocarbons by using linked converters
Inventor: MORITA TETSU
IPC: F01N13/04
Filed: 1977-03-25
Abstract: The catalytic converter unit for producing gaseous IC engine fuel from fluid hydrocarbons, comprises a number of converter units, working on the endothermic principle. These (4a-d) are arranged in parallel at the outlet from an exhaust gas mixing chamber (6) on the engine. Throttle valve (5a, b, c) control the gas flow into all but one (4d) of the converters; there are also throttle valves (10a, b, c) in all but one (8d) of the liquid-supply lines (8a-d) to the converters. Pressure variation in the engine inlet manifold is used to control these valves so that gas and liquid flow is to one converter only at idling, the others being brought in progressively until all are in use at full load. Gaseous fuel discharge is through a common line (9). Gas turbulence at exit from converters in use causes reverse flow into any that are shut off, pre-heating the latter so that they are ready to function properly when required.

Title: Slab roughing train for continuous hot strip rolling mill - where floor length of roughing train can be reduced
Inventor: KNUEHL HELMUT
IPC: B21B37/48
Filed: 1977-05-14
Abstract: Slabs are simultaneously rolled in the roughing train of a continuous hot strip mill, where train has six roll stands which are located very close to each other, pref. without using intermediate roller tracks for the slabs; the rolling is achieved by using min. tension on the slabs during the roughing passes. The slabs, initially 200-300m. thick, are rolled down in train to 40-60mm., but the front end of one slab must not touch the tail end of the next slab in front and so normally the roughing train is ca. 70 metres long. The tension regulators drive stand motors to obtain min. tension on the slabs travelling one after the other through stands. The result is that the stands need only be 5-6 metres apart from each other so there is a large saving in the length of factory required to house the roughing train.

Title: Stenter for thermal treatment of piece goods - is shorter in length but has increased capacity
Inventor: VOSWINCKEL GERHARD DIPL ING
IPC: D06C3/02
Filed: 1977-12-23
Abstract: Textile piece goods are processed continuously under tension by passing them first through a heat treatment zone and then through a cooling zone. In a first section of the heat treatment zone, the goods are tensioned laterally, whilst being raised to the required temp. In the second section the goods are maintained at the required temp. under lengthways tension. Thereafter they are fed to the cooling zone. Used for condensing and fixing, etc. of piece goods, the heating medium being blown through nozzles, whilst the goods are held in clips or on pins. The invention makes it unnecessary to have a plant of great length which is expensive both to install and operate. It provides the capacity for handling a large quantity of goods in a short structure, so that long contact times with a large throughput are possible. Lateral stretching to avoid deformation of the fabric is only essential in the first heat treatment section. Velvets can be treated by passing them after consolidation over rollers in a number of layers in the second section.
