Abstract: A sealing arrangement is disclosed for sheet-like elements such as flat wall elements (e.g., pasta dryers). A separation joint can be sealed against penetration gases or steam by placing level sealing elements on both sides of the separation joint, the sealing elements being braced against each other by connections, such as screw connection.

Abstract: A roll mill for comminuting and homogenizing viscous masses, in particular for dispersing and uniformly distributing solid particles suspended in a binding agent. The roll mill has at least two rolls pivoted around their longitudinal axes, wherein the rotational axis of the first roll is fixed in place, and the rotational axis of a second roll is movably mounted, as well as at least one pressing device for pressing at least one roll against the other roll. Roll pressing takes place by way of a mechanical-pneumatic pressing device, which has a force transducer and a pneumatic drive. The roll surfaces or process surfaces are made out of a metal-free ceramic material.

A first plane defined by the rotational axis of the front roll or feeder roll and by the rotational axis of the middle roll, and a second plane defined by the rotational axis of the middle roll and the rotational axis of the back roll or transfer roll, are inclined relative to each other by an angle of between 10° and 90°. The roll surfaces or process surfaces are made out of a metal-free ceramic material.

Abstract: A pasta dryer comprising a conveyer belt for conveying and delivering dried pasta, the conveyor belt being configured as a continuous conveyor. To operate more efficiently, the conveyor belt has a delivery table in the vicinity of an idler, the table comprising an attached fixed or sliding product collection tray. The reinforcement elements of the conveyor belt are preferably S-shaped.

Abstract: A drier for continuous flow drying of food products, especially pasta, inside the drier with adjustable and/or conditioning zones along the continuous flow path of the product. The inside of the drier can be accessed by a maintenance technician and the respective horizontal segments of the side walls are sub-divided perpendicular to the direction of the continuous flow from top to bottom into respectively at least two vertical segments which are respectively curved in an outer direction and which can also be moved away from the housing in an independent manner, enabling the maintenance technician to have access to the inside from the respective point of a vertical segment moved away from the housing.

Abstract: An apparatus for cleaning pasta presses, particularly for the "in situ" cleaning of the screws of screw-type machines, kneader mixers and the like in the pasta industry.This is effected without dismantling the machine by conveying cleaning liquids through the screw-type machines which are closed in liquid-tight manner. The cleaning liquids are preferably recycled and filtered.

Abstract: This invention pertains to a process as well as an apparatus for the production of elongated pasta products, particularly lasagna, wherein the pasta products are formed via a pasta production apparatus in parallel lines, positioned on drying rods, dried and upon solidification, cut into packaging lengths and packed for consumer use. After cutting, the lasagna are moved, in series, via slides, and stacked in portions, of predeterminable numbers, at a conveyor. The conveyor preferably takes the form of a ring-type conveyor for the serial packaging of these portions, whereby inspections, additions and exact weight determination of these portions can be accomplished.

Abstract: The inventive method and apparatus suggests guiding the pasta directly into a drying climate after exiting from the die. Pasta strands of short goods are fed directly into the drying device from the extrusion die. The pasta strands can be cut either directly at the extrusion die or subsequently into packaging lengths after drying by means of an additional cutting device. It is possible to operate only the initial drying in this way, particularly to heat up the goods and then to carry out the final drying in a manner known per se, e.g. by portions. However, it is also possible to carry out the drying in its entirety, i.e. the pre-drying and final drying, according to the invention, particularly for short goods. The goods can be intensively dried at previously unaccustomed temperatures of 90.degree. C. to 120.degree. C., particularly during final drying from 15% to less than 13% product moisture.

Abstract: A roller mill, in which the milling rollers are pressed together with high pressures, has a fluidic device for imparting the respective pressure. This fluidic device comprises piston-cylinder units and a pressure line for the fluid. In order to obtain a skewing of at least one roller in dependency upon the pressure exerted by the fluidic device, pressure sensitive means are interposed between the pressure line and a displacing device for the skewing angle. In this way, a pressure signal may be transferred to a converter for converting the pressure into a corresponding displacement stroke. Preferably, at least one roller has a basic camber or crown which corresponds to a pressure within a lower range of the occurring pressures.

Abstract: A mobile subscriber station served by a telephone network is coupled by a radio link with an individually associated stationary relay station directly connected to that network. The tow stations are able to communicate with each other, over a radius of about 50 meters, on any of 40 channels available to all the posts of subscriber and relay stations in the neighborhood. Each station of a post includes a transmitter and a receiver operating at about 900 MHz; in the idle state of the post, the receivers of both stations continuously scan the available channels to determine their free or busy condition. A person wishing to make an outgoing call causes the transmitter of the subscriber station to send out a predetermined code word which is picked up by the receiver of the associated relay station in its scanning operation and, upon verification by a code comparator, initiates the emission of a handshake signal to the subscriber station whereupon the channel is seized to let the call proceed over the network.

Abstract: The actuation apparatus for the movable mold parts or halves of an injection molding machine, especially for the manufacture of foamed plastic articles, comprises pairs of toggle-lever rods with the toggle-lever rods of each pair being movable in essentially parallel planes which are spaced from one another. The toggle-lever rods of each pair are arranged between a movable mold support plate and a stationary toggle plate, and can be conjointly selectively extended or retracted by means of a driven toggle head. The planes within which the toggle-lever rods operate extend obliquely across the movable mold support plate and the toggle plate, and the pairs of toggle-lever rods are arranged symmetrically on opposite sides of a vertical plane of symmetry containing the central longitudinal axis of the machine.
