Title: Removing foils from stack while removing intermediate protective layer - involves friction roller moving underneath raised edges of top foil and layer which are pressed down in centre.
Inventor: RASCHKE JOSEF
IPC: B65H3/40
Filed: 1992-05-25
Abstract: The top foil (F) is pressed down in the centre by the plate suction means of a foil lift unit (FH) so that the edges are raised and the friction roller is moved in. The roller is driven with a rotary direction (5) directed inwards at the circumference from the foil edge. The topmost intermediate layer is pressed down at the edge over the friction roller, the topmost foil (F) is lifted and the topmost intermediate layer is then removed. The intermediate layer released by the friction roller can be pressed further down by a brush on the roller and/or by blowing in air. USE/ADVANTAGE - Controlled automatic removal of intermediate layers of foils from stack for use in continuous production lines.

Inventor: AUGENREICH KLAUS DIPL ING
IPC: H02P3/04
Filed: 1992-06-16
Abstract: The invention relates to a drive circuit for a DC-operated brake of an electric motor, especially of a pole-changeable three-phase motor, having an electromagnet (which has one coil) for ventilating the brake, a rectifier circuit (which is connected to the voltage supply of the electric motor and supplies the coil and a switching system having electronic switching elements for the coil), and having a freewheeling circuit for the coil. In order to obtain a drive circuit which is of simple construction, makes possible minimum switching times of the brake and at the same time makes possible a high level of capability for the switching operation of the brake to be repeated, it is proposed according to the invention that an electronic switching element (15) for the coil (3) be controllable by the switching system (9) in such a manner that, when the electric motor (1) is switched on, said electric motor (1) is fully driven (thus producing overexcitation of the coil (3)) and, after a short time interval, is controlled to reduce the coil voltage to a preselected voltage, in a pulse-width modulated manner, and a further electronic switching element (14) is arranged in the freewheeling circuit, which switching element can be driven by the control system (9) in parallel with the switching element (15) for the coil (3) in order to switch the brake (2) on and off quickly. <IMAGE>

Inventor: KAUFMANN REINHOLD
IPC: B30B15/34
Filed: 1992-07-07
Abstract: The invention relates to a sealing calender and a method for producing sealing plates on such a calender, in the stands (1) of which there is mounted a heating roller (2) of large diameter which is heated by means of a flowable heating medium and a pressing roller (3) of smaller diameter, by inserting a doughy mixture, which is composed of premixed rubber, fibres and solvents into the nip, rolling this mixture in very fine layers during a large number of rotations of the heating rollers and fully vulcanising the rolled-on layer during the rotations of the heating rollers. The object of the invention is to make it possible also to process the sensitive mixtures of rubber compounds, fibres and solvents used today in such a way that the temperature of the surface of the layer is as homogeneous as possible, independently of its thickness, and remains equal to the temperature of the heating roller surface. The invention achieves this object by heating the rolled-on layer by means of outside heat sources (4) in addition to the heating roller heating system. To achieve this, the sealing plate calender is designed in such a way that at least one energy source which emits heat is arranged about part of the circumference of the heating roller in such a way that the part, which is additionally heated from outside in this manner, of the circumference of the heating roller is heated over the entire width of the heating roller. <IMAGE>

Title: Reinforced large dia. thin wall tube mfr. - by longitudinal or spiral seam welding simultaneously with stiffening rib welding
Inventor: TOMSEN HARALD ING GRAD
IPC: B21C37/12
Filed: 1992-09-16
Abstract: In the mfr. of a large dia. thin-walled tube having spaced external stiffening ribs, in which strip is formed to a tube and the ends are joined by longitudinal seam welding, the novelty is that either (a) strip, of length required to form a tube section, is bent outwardly at one or both edges prior to longitudinal seam welding and the individual tube sections are welded together at the raised edges (ribs); or (b) at least one sheet rib is welded onto each tube section simultaneously with welding together of the individual tube sections. In a similar process, employing spiral seam welding instead of longitudinal seam welding, the novelty is that either (a) the strip is bent outwardly at one or both edges prior to spiral seam welding and the raised edge is welded to an adjacent raised or flat strip edge; or (b) a sheet rib is welded onto the strip edge simultaneously with welding together of the strip edges. The fig. shows a tube formed of three tube sections (10,20,30) which are welded together at the raised edges (b) of their component strips and which are individually welded by longitudinal weld seams (a). USE/ADVANTAGE - Used e.g. for mfg. 1-3m dia., 1-4mm thick tubes useful as core pipes for concrete pipes. The shape stabilising ribs are welded simultaneously with tube mfr. so that the mfg. process is simplified.

Title: Thawing plate for deep-frozen food, in particular meat products, for microwave appliances
Inventor: WUELFING DIRK
IPC: H05B6/64
Filed: 1993-07-30
Abstract: The frozen food which is introduced into microwave appliances and is to be thawed starts to cook even if the level or wattage specified as favourable for the thawing is kept to. This leads, especially in the case of meat products, to a considerable impairment in taste or to the frozen food becoming unusable. The thawing plate helps to prevent this initial cooking. To avoid the initial cooking, the thawing plate has a structure similar to a bed of nails inside a dish-like moulding made of heat-resistant and microwave suitable material. The thawing plate may be made in one piece (e.g. glass). By virtue of the pin arrangement (rounded-off pins), the contact surface between thawing plate and frozen food laid thereon is kept as small as possible, thereby preventing the initial cooking, which in most cases takes place on the underside of the frozen food, i.e. at the point of contact with the support. The liquid produced during thawing flows down the pins and is collected in the dish moulding. The thawing plate finds application in all microwave appliances of the domestic and catering sector. <IMAGE>

Title: Contaminated soil treatment esp. to remove hydrocarbon(s) - involves layered storage in connected open-ended cells
Inventor: MUELLER ALFRED
IPC: B09C1/00
Filed: 1993-08-05
Abstract: Treatment of soil, contaminated by noxious volatile components (esp. hydrocarbons), involves comminuting the soil to a loose bulk material which is then delivered into a cell which is sealed around its sides and closed at the bottom by the loose soil itself, the soil being stored in layers within the cell and being repeatedly turned over vertically in layers. Appts., for carrying out the above process, comprises a silo battery (12) of connected cells (14), each of which has a discharge gap in its bottom region spaced from the bottom (10) of the silo battery. A transverse conveyor travels below the discharge gaps and is connected to a top conveyor (40) which is located above the cells (14) and which is opt equipped with dropping points (42) for each of the cells. Soil is constantly withdrawn in layers from the cell bottoms and returned to the cell tops. The soil has a dwell time of about 100 days in the cells and the soil is repeatedly wetted with a treatment liq. during this dwell time. USE/ADVANTAGE - For treating soil contaminated by hydrocarbon spills, e.g. at airports. Various solids with different contaminant contents can be separately treated without affecting the requisite dwell times.
