Abstract: The twin fourdrinier section of a paper-making or cardboard mfg. machine has a fourdrinier support surface within the closed loop of at least one fourdrinier, only at the start of the section where the rigid bars face the bars with a pliable support.     The support surface is only within the fourdrinier loop acting with the bars with pliable supports, or only within the fourdrinier loop with the rigid bars. The facing bars form at least part of the fourdrinier support surface to give a sandwich zone, where the length of the support surface is 10-60% of the sandwich zone. The support surface is partially within and partially outside the sandwich zone, or is wholly within the sandwich zone. The location of the support surface can be adjusted, parallel to the direction of fourdrinier travel. The fourdrinier support surface is a plate or box-shaped component on pliable supports such as springs, pneumatic cushions and the like, to bear against its fourdrinier with a selected pressure force. The leading edge of the support surface is supported by a linkage. The fourdriniers travel horizontally through the double fourdrinier zone, where one is the upper fourdrinier and the other is the lower level.

Patent DE-4305601-A1 (DE)
Title: Rotary closure for bottles and containers
Inventor: SCHEFFLER HELLMUT
IPC: B65D47/26
Filed: 1993-02-24
Abstract: Rotary closures for bottles and containers must either be screwed completely on or off or caps have to be pivoted up and down. In this case, there is no possibility of regulating an even outflow quantity.   The new rotary closure brings about total opening or closing of the outlet aperture by means of a limited rotation as well as partial opening as desired to regulate the outlet quantity. This is brought about by means of radial displacement of two apertures (7 and 13) relative to one another by rotating the closure sleeve (10). By means of the shaping (11) and an edge (12), the closure sleeve (10) is braced in a sliding manner against a bead (6) of an insertion or threaded sleeve (1). At the same time, together with a sealing ring (9) in interaction with round cutouts (8 and 14), the bracing brings about an elastic seal. Stops which are present bound the respective end positions. The rotary closure is either pressed into bottles (5) with a shank (4) or screwed onto bottles or containers (3) by means of a thread (2). The new rotary closure simplifies the use of bottles and containers and makes possible regulation of the outlet quantity or outlet speed. <IMAGE>

Title: Device for the removal of cleaning bodies at compensation stopcocks of dispensing systems
Inventor: BROGHAMMER RUDOLF
IPC: B67D1/07
Filed: 1993-06-19
Abstract: The invention relates to a device for the removal of cleaning bodies which have cleaning fluid washing over them, at compensation stopcocks, in the drinks line during cleaning operations. In this arrangement, a laterally projecting extension piece (22), which is supplemented by a screwed-in tube piece (23), is integrally formed on an intermediate piece (1) provided upstream of the compensation stopcock (3). Arranged in the extension piece (22) is a valve piston (32) which is subjected to the action of a helical spring (33) (Figure 1). In this position, a lateral through-passage opening (29) in the extension piece (22) is closed by the valve piston (32), which opening serves for the washing-out of the cleaning body (13). During the cleaning operation, the cleaning body (13) is washed into the intermediate piece (1) by the cleaning fluid and, there, comes to bear in front of a tapered portion (19) in the through-passage (18). In order to discharge the cleaning body (13), the valve piston (32) is displaced axially counter to the action of the helical spring (33) in the extension piece (22) and/or tube piece (23), and the through-passage opening (29) is thus opened. Consequently, the cleaning body (13), which is acted upon and advanced by the cleaning water in the drinks line, is displaced into the extension piece (22) and, therein, is washed out via the through-passage opening (29) and the tube extension (57). <IMAGE>

Title: Waste pyrolysis using superheated steam - with uniform controlled heat input and waste heat recovery
Inventor: SCHMIDT EDWIN
IPC: C10B13/00
Filed: 1993-08-23
Abstract: A waste pyrolysis process is carried out by directly contacting the waste with superheated steam which causes mixing, comminution and vol. redn. of the waste in a heating chamber, the resulting pyrolysed prod. being pressure impregnated with superheated steam in a cylinder and then autogenously compacted and briquetted by pistons by means of the vacuum effect of cooling the cylinder outer wall. The steam may be previously used or directly produced steam and is superheated by counter-current heating, its waste heat content subsequently being used for steam prodn. Also claimed is appts. for carrying out the process. Pref. the heating chamber contains a conveyor screw with an axial conical passage enclosing a rotor shaft and a cutting blade rotor mounted on the rotor shaft. An inner cylinder is located within and spaced from the cylinder and has bottom openings or perforations, a piston being moveable within the inner cylinder and having an outwardly extending piston rod. ADVANTAGE - The process has low heat losses and provides uniformly distributed direct heat input, precise maintenance of the preset pyrolysis temp. and max. utilisation of waste heat.

Title: Sludge dewatering and drying in oxygen-deficient atmos.
Inventor: ZACHER UWE DIPL ING
IPC: C02F11/12
Filed: 1994-03-07
Abstract: In a combined sludge dewatering and drying process, the oxygen content of the drying gas is reduced ahead of the dryer to below the limit for combustion and explosion, and part of the exhaust gas, after sepn. of dust, is returned to the drying gas circuit and mixed with de-humidified, hot, oxygen-deficient gas to form the drying gas. The process is of the type used for drying sludges having a dry content of 0.5-10%, such as industrial, brewing and sewage sludge treatment. The sludge is treated in a fully jacketed screw or sieve screw centrifuge to form a dense phase which is ejected at high velocity in the form of fine particles which are mixed during their trajectory with the drying gas, deflected, and at least superficially dried for subsequent pneumatic transport. Also claimed is a centrifuge dryer for sludges.
