Patent DE-4308305-A1 (DE)
Title: Paper web heating cost effectively - uses perforated roller with inner hot stream feed to raise paper temp. before passing through press rollers
Inventor: STEINER KARL
IPC: D21F3/02
Filed: 1993-03-16
Abstract: The blower roller, to heat a paper web with steam before it passes through a roller gap, has at least a partially perforated roller mantle with a feed for hot steam to its interior. The blower roller is pref. directly in front of the gap between press rollers. The paper web is supported by an outer blanket or fourdrinier between the roller surface and the paper web. When working with thin paper materials, the leading drying cylinder can be operated at a higher temp., with paper preheating, without the risk of paper adhesion to the drying cylinder. USE/ADVANTAGE - The roller system is for the adjustment of the dry content of the web through the application of heat. The paper is sufficiently heated before passing through the roller press, effectively and cost effectively

Title: Pulse converter for pulse transmission to load capacity - has start of each input pulse triggering current pulse charging load capacitor via transformer
Inventor: NIGGEMEYER GERT GUENTHER
IPC: H03K5/02
Filed: 1993-04-15
Abstract: The circuit energises a FET gate electrode and has at least three transistors, two diodes, a capacitor and two transistors, separating a primary side circuit, generating current pulses, from a secondary (dis)charge circuit. The start of each input pulse (PWM) triggers a current pulse (11), charging in a single pass a load capacitor (CGS) via a transformer (XF1). At the end of each input pulse, a current pulse (12) is triggered, rendering a transistor (XR3) conductive via a second transformer (XF2), discharging the load capacitor and simultaneously generating an output pulse (UGS). USE/ADVANTAGE - For high performance, isolated gate drive. Facility for steep flank pulse transmission and high follower frequency, without IF conversion.
Patent DE-4317508-A1 (DE)
Title: Two-phase feeding unit
Inventor: ICKING PAUL
IPC: A01K5/02
Filed: 1993-05-26
Abstract: Since the two-phase feeding unit according to the invention consists of component parts which are known in principle in conventional sow-feeding units for dry feed, many operators of conventional units are thus also afforded the possibility of making ecological and economic improvements to their facilities. The distribution of separately stored ready-mixed feed via one and the same delivery unit to animals of different types is not only more cost-effective compared to two independent supply units; it also affords the advantage, by simple allocation of the dosing devices to the corresponding release station, to choose between the two phase-specific feed mixes involved, in order to supply both feed types at one feeding station in identical portions.

Patent DE-4329802-A1 (DE)
Title: Process for desalting salt water and sterilisation using an electrodialyser
Inventor: FINKE PETER OTTO
IPC: B01D61/44
Filed: 1993-09-03
Abstract: The novel electrodialyser serves for electrodialysis, but has an additional membrane upstream of the porous anode and porous cathode. Thus separate anode and cathode compartments and prechambers are formed through which the salt water passes through the overflow channels into dilution chambers, where the desalting process takes place by membranes which form the concentration chambers in which the salt brine which is discharged collects. At salt concentrations of < 1 g/l, salt brine is fed from the concentration chambers to the intake stream, from which salt brine, the water hardness salts have been previously been precipitated by addition of alkali from the cathode chamber, slow passing through from behind the porous cathode comprising sintered metal in order to prevent metal deposits on its surface from the dissolved salts. A part-stream of the desalted water exiting from the cathode prechamber is fed from the rear to the front to the anode chamber through the porous electrode which comprises sintered metal, where it absorbs hydrogen ions and then is admixed again with the end product, by which means its pH can be adjusted.

Title: Pattern cutter for sheet material correcting distortion errors
Inventor: JUNG ROLF DIPL ING
IPC: B26D7/01
Filed: 1993-12-29
Abstract: A pattern cutter for sheet material (20), e.g. cloth layers, has a conveyor table (2) comprising a driven transport belt (16) which runs round direction changing rollers (10,11). The belt is made of air-permeable supporting material (18) forming a placement mat for the sheet material on the upper side of a forward run region (14) which is included in an induced low pressure space.

Abstract: A process for drying a paper web and a drying section of a paper making machine. The drying section includes at least one drying group comprised of a plurality of drying cylinders, each at least partially wrapped by a web to be dried. The drying cylinders having peripheral surfaces heated for drying the web moving therepast. The peripheral surfaces of the drying cylinders in the drying groups are rotated at the velocity of the web along the web path. At least one of the drying cylinders in at least one drying group is driven to rotate at a speed that is different than the speed of the web moving past the at least one cylinder. The at least one cylinder may be selectively driven to rotate faster or slower than the speed of the web moving therepast, which applies more heat to the paper web. The invention is adaptable for a single tier drying section and/or for a double tier drying sections or for other drying section arrangements. The operation of a drying cylinder at a different speed than the other cylinders is useful for one or more than one drying cylinder in a drying group and where a drying section is comprised of more than one drying group, is useful for a drying cylinder in one or more of the drying groups.
