Abstract: A method of desulfurizing coke oven gas comprises directing the coke oven gases upwardly and in a hydrogen sulfide scrubber tower, washing the coke oven gases in a cyclic ammonia washing including admixing sulfur compounds containing waste gases and without cooling with ammonia in a degasifying unit which is supplied with ammonia containing water which is advantageously obtained from a tar separator and using the heat content of the waste gases to expel the ammonia from the water, and directing the waste gases laden with the expelled ammonia into the tower. The waste gases advantageously come from a Claus plant process and they are laden with ammonia and they are advantageously directed into the upper portion of the scrubber tower. Ammonia water is circulated in an ammonia circuit from an outlet which is advantageously located in the upper portion of the tower to an inlet which connects to the tower above the outlet.

Abstract: A freight car is constructed with an undercarriage having a flat cargo floor and with an upright fixed end wall at each end of the floor. A gantry in the form of an arch extends upwardly from the floor substantially centrally between the end walls and a hood support rail extends between the fixed end walls on each side of the floor. The space above the floor is covered by a hood which is of a length to extend between the gantry and one end wall and which includes a roof portion which overlies the gantry and the one end wall and side wall portions which extend downwardly from each side of the roof. The side wall portions carry rollers or casters which are engageable with the rail for supporting the hood for movement along the rail. The hood may be moved when it is in an open position along the rail for example to completely uncover the space between the gantry and one end wall.

Abstract: An improved method for the automatic packing of articles in which bag sections are successively made of tubular plastics bag material which is intermittently conveyed. Goods are charged into a bag section formed at the leading end of the bag material. Thereafter the goods-charged bag section is heat-sealed at an opening portion thereof and separated from a subsequent bag section of the bag material. In accordance with the invention, before charging the bag section with goods, a piece of reinforcing sheet is inserted in and secured to the foremost bag section to form a reinforced handle portion having an opening for suspension of the finished bag.

Abstract: The spindle can be rotated by way of a set wheel, and thus displaced within the spindle guide. At the end of this displacement, the spindle butts against one of the set screws of a turret stop provided on the rest plate. The spindle can be locked to the respective set screw by way of a swing extension. The spindle may be hollow to pass therethrough a tool and finely adjust the set screw already locked to the spindle.
