Abstract: To cross-fold a moving web into one-third lengths, a cutter blade cylinder (1, 26) is at a cutting position with a counter cylinder (4, 28), which carries needles and may also carry cutting knives. The cutting knives are arranged to cut the web into a format of one-third/two-third length, respectively. The needles (5, 6) on the cylinder transfer the one-third cut element to a second needling cylinder (9, 32) which re-transfers the cut elements to a group of needles (6) on the first needling cylinder (4, 28) so that the one-third length portion is superimposed on the two-third length portion. These two superimposed portions are then transferred to a combination needling-folding blade cylinder (10, 33) which folds the two-third portion in half and transfers the fold to a folding jaw cylinder (14, 38) so that the one-third portion is interlaced into the two-thirds portion.

Abstract: It is proposed, in the case of at least one transport and discharge runner installed at a tapping orifice of the metallurgical furnace and a transfer station having a swivel or tilting runner in which the molten metal flows from the discharge runner by way of a distribution system into the outlet openings from which it flows into a preferably movable casting vessel, to cover the discharge runners conveying the molten metal from the tapping orifice of the metallurgical furnace with cover hoods, to screen off the transfer station in a substantially gastight manner, to sweep these interiors with inert gas and in addition to screen off the molten metal discharge stream from the outlet opening to the casting vessel by means of a pressurized inert gas covering which prevents air access and is substantally annular in cross-section. By these means, fume production is effectively avoided.

Abstract: A latch for retaining together two parts of a piece of luggage has a latch element projecting from one of the parts, a housing mounted on the other part and shaped to receive the latch element, and a latch dog movable in the housing between a retaining position preventing the latch element, when engaged in the housing, from withdrawing from the housing and a freeing position permitting the latch element to withdraw from the housing. At least one operating element in the housing is displaceable in first and second nonparallel directions between an actuated and unactuated positions for, on displacement in the first direction and thereafter in the second direction, displacing the dog into the freeing position and for, on displacement in only one of the directions, leaving the dog in the retaining position. Thus if the operating element is accidentally hit by something the latch will not open.

Abstract: To move folding jaws (4, 5) in a scissor-like or pincer-like movement symmetrical with respect to a center line (CL) and to permit adjustment of the gap or opening of the jaws, for acceptance of folded substrates of different thicknesses, the jaws are coupled together by a rotation reversal arrangement (14, 114, 112, 314) so that rotation of one of the carrier bodies (6) will be transferred as an equal and opposite movement to the other (7) of the carrier bodies. An axial position adjustment spindle (25, 125, 325), controllable by a hand wheel (29) or servo motor (30), changes the axial position of gears rotating or rotating with a shaft (2, 202, 402) of a folding jaw cylinder (1, 201, 401), at least some of the gears or gear pairs having inclined teeth, to thereby transfer a positioning movement into a relative rotary shift of the respectively rotating gear with respect to the gear driving the shaft, thereby causing rocking or tilting of the folding jaw carriers (6, 7).

Abstract: To provide for gentle braking by braking fingers (12) located in axial slots between paddle wheel vanes or blades (9, 10) of paddle wheels (8), the fingers have an outer contour which is shaped and dimensioned, at least in the inlet region of gaps (11) for the printed product forming an intersection angle (.alpha.) defined by the axial projection between the contour of the braking fingers and the adjacent inner surface (91) of a vane or blade to continuously increase during rotation of the paddle wheel vanes or disks, to thereby define effective gaps of continuously decreasing width during rotation of the paddle wheel vanes. Preferably, the position of the fingers is adjustable along a predetermined direction (X) by an electrical closed loop positioning system (13 -20, 43), receiving input signals (44, 45) representative of thickness of products and machine speed and, preferably, also emergency control signals (48) to control the position of the fingers with respect to the vanes or blades.

Abstract: To permit central control of shifting of folding blades and puncture needles on a combination collection or assembly and folding cylinder (9), the cams (23, 25l) have associated therewith rotatable cam cover disks (62, 61) which are driven from the main machine drive, for example via a drive gear (20) coupled to the cylinder (9). An additional rotary motion is superimposed to permit shifting of the cover disks and thus selectively different modes of operation, for collection or assembly, or non-collection of sequential sheet products placed on the cylinder. The superimposed motion arrangement comprises a hollow coupling gear (29) which is coupled to a worm (28) coupled therewith, the worm being engaged by axially shiftable roller bolts (36, 37), the axial position of which is controllable by an electrical positioning motor (57) via a shifting plate (47) upon rotation of a positioning spindle (52).

C. and in which the rotating furnace is heated in counter flow by a burner through the central nozzle of which oxygen and/or air is supplied. The burner is located at the reaction product discharge end of the furnace and 10 to 90% of the coal for the raw material mixture is introduced into the rotating furnace through the reaction product discharge end, with at least part of this coal being introduced through an outer nozzle of the burner.

Abstract: The invention concerns a float-controlled flow-control devie for the outlet from a sewage system, especially a rain basin. The bearings for the pivots (7 & 8) that the float arm (4) and the shutter (2) rotate on are mounted on a displaceable structure (3). This makes it possible to vary the outflow volume to be controlled even when the device is in operation, and hence to control it remotely as well.

Abstract: A process for the preparation of ammonium nitrate by the reaction of nitric acid with ammonia in two stages at elevated temperature, in which the first stage is carried out at elevated pressure and the second stage is carried out at atmospheric pressure. The heat of neutralization released in the first stage is used to vaporize a portion of the reactor contents, the remaining heat of reaction being utilized to produce steam. The vapor leaving the first stage develops a pressure which controls the valve regulating the amount of heat recovered by steam generation. The valve is opened when the pressure of the vapor exceeds a set value, usually in the range of 3.4 to 4.8 bars. Decomposition products of ammonium nitrate are also measured and override the pressure regulated control of the proporiton of heat recovered by steam generation, so as to maintain ammonium nitrate decomposition within acceptable limits. An apparatus for carrying out the process is also disclosed.
