Abstract: Pull-out sliding unit for installation in a motor vehicle has a sliding unit that can be pulled out like a drawer, which may, for example, be constructed as a drinks holder or as a tray surface, provided for installation in a fascia of a motor vehicle. In order to be able to remove the sliding unit easily from the device and exchange it, a sliding block engages the sliding unit and disengages by two wedges onto which the sliding block slides when the sliding unit, after being unlocked, is pulled out of the device beyond its open position.

Abstract: A holder for drink containers in a motor vehicle has a slider member that can be pulled out and on which are mounted pivot arms which, when pulled out, pivot laterally outward, and which, with cut-away portions in the slider member, form insertion openings for drink containers, and has supports which pivot downwards when the slider member is pulled out. In order to support securely drink containers of different sizes which are inserted, the supports are pivoted outward, forcibly controlled, by the pivot arms through half the pivot angle of the pivot arms.

Abstract: A method and apparatus is provided for air conditioning two passenger decks in an aircraft, especially a high capacity aircraft. The engine tap air stream is provided for air conditioning the upper deck passenger cabin and the lower deck passenger cabin. The air stream is cooled in at least one air conditioning plant, mixed with recirculated air from the lower cabin in at least one premix chamber, and then mixed with recirculated air from the upper cabin in local mixing chambers. The finished air streams are directed to the upper deck and the lower deck passenger cabins. The upper deck exhaust air is essentially completely used as recirculation air being mixed with the conditioning air in the local mixing chambers. The lower deck exhaust air is partially used as recirculation air being mixed with the conditioning air in the premix chambers, and is partially exhausted overboard.

Abstract: In the operation of the rotary kiln provided at its charging end with a central burner, solid reducing agents having a high content of volatile constituents are used and the charge and the gas atmosphere are conducted in cocurrent streams. To avoid a high heat load per unit of volume in the heating-up zone and yet to increase the heating-up rate, a solid carbonaceous reducing agent having a high content of volatile constituents is charged together with the iron oxide-containing material into the charging end of the rotary kiln, oxygen-containing gases are blown through nozzle blocks into the free gas space and into the charge in the heating-up zone, and oxygen-containing gases are blown through nozzle blocks into the free kiln space in the reducing zone.

Abstract: A procedure and an apparatus for the quantitative determination of cations and anions by ion chromatography is described which can be used, for example, to test drinking water, river water or water in drains. The sample is injected into a buffer stream which comes through a chromatography column. The eluate from the column is measured in a conductivity detector, the background being suppressed in a new cell. The cell consists of two ion exchange membranes which are not permeable to the ions to be measured and two electrodes which set up an electric field across the membranes. The highly dissociated ions of opposite charge in the eluate are exchanged into compounds of low conductivity and removed from the cell.

Abstract: A device for varying the angular setting of the blade of an earthmoving vehicle by means of a pair of double acting hydraulic cylinders in which only one of the cylinders receives pressure direct from a pump. The piston of that cylinder acts on one end of the blade and at the same time transmits pressure fluid through a hydraulic circuit to the piston of the other cylinder acting on the other end of the blade whereby the two pistons move in opposite directions. The hydraulic circuit includes a control valve for reversing the direction of movement of the pistons, the same cylinder being pressurized by the pump in both directions of movement of the pistons. Pressure fluid leakage loss compensating means are provided in each piston.

Abstract: A center support member for a tiltable swivelling grading blade on an earthmoving machine which prevents the occurence of internal stresses in the blade generated by tilting of the blade is in the form of a ball and socket joint attached to the center rear of the blade and to a carrier frame on the machine. A shaft slidable in a sleeved mounting carries the ball portion of the joint at one end and the other end of the shaft is spring urged towards the blade by spring means in the sleeved mounting. Stop means in the sleeved mounting limit the stroke of the shaft. Additionally, a piston engaged by the spring means in a chamber in the sleeved mounting is arranged to force lubricant through a feed line to the shaft in response to axial movement of the shaft.

Abstract: An adjustable time fuse includes an electrolytic cell with the anode and cathode connectible in two circuits with opposite polarity and a battery connected in the circuits. One of the circuits causes an element of the electrolyte to be deposited on one of the electrodes to activate the cell and the other causes the same element to be removed from the electrode. When this element is completely removed, the internal resistance of the cell increases rapidly. This increase in resistance triggers a thyristor to allow a condenser to discharge through a primer to produce the desired action.
