The slit-like aperture of the dispenser is formed by a fixed front wall and a moveable rear wall selectively moving toward and away from the fixed front wall.

Abstract: A method and apparatus for providing secure communication on open networks. Each port of the network is provided with a security entity which monitors the communication between one port to the other. End stations connected to the ports communicate with other end stations by transmitting data to the port and receiving data from the port. The data is sent out in data packets with a destination address and a source address. Each port has its own unique address. The security entity checks data packets coming into the port for a destination address. The destination address of incoming data packets is compared with the port address of the affiliated port. Also, outgoing data packets from an end station to a port are also monitored by the security entity. The security entity compares the destination and source address of the data packet with the affiliated port address.

Abstract: A process for determining coordinate values of touchdown sites of a needle for forming sewing patterns with an electronically controlled sewing machine, which is equipped with a feed dog performing only relatively small amounts of displacement and with a needle pivotable in one direction of displacement of the feed dog. The coordinate values for a straight seam section, the consecutive touchdown points of the needle, are determined when the maximum amount of feed of the feed dog in the X coordinate direction and/or the sum of the maximum amount of the lateral movement of the needle which is possible at a given needle position and the maximum amount of feed of the feed dog in the Y coordinate direction is exceeded. The seam section is subdivided by equidistant intermediate touchdown sites, the distances between which in the direction of movement of the needle are composed of a constant percentage of the lateral movement of the needle and of a constant feed percentage of the feed dog.

Abstract: In a process known of per se for manufacturing plastic pipes, in which a liquid resin, a catalyst and sand and glass fibres are introduced into a centrifugal drum where the pipe is formed as the plastic sets, it was previously customary to start or stimulate the thermosetting process by blowing hot air into the centrifugal drum. The air escaping thereby from the inside of the drum contains solvent vapours which pollute the environment. The improved process consists in that the heat required to start the thermosetting process is no longer supplied from the inside by means of hot air, but by means of hot water which is sprayed onto the outside of the centrifugal drum and is fed through a hot water circuit and, after the exothermic thermosetting begins, heats up again in the latter to at least the original temperature, thereby drawing off heat released by the process. Further cooling is achieved by a cold water circuit, which can be switched on selectively to spray the centrifugal drum.
