Patent DE-4136112-A1 (DE)
IPC: H04N7/24
Filed: 1991-11-02
Abstract: To process picture source signals and/or sound signals for transmission purposes, the signals are individually digitised by means of A/D converters. The digital signals are then digitally modulated and transmitted in time-division multiplex. After the transmission, reconversion into a digital intermediate-frequency range or conversion (DFU1, DFU2, DFUn) into various frequency slots for forming a digital frequency-division multiplex signal can take place, which signal can be fed into a distribution network. The method according to the invention allows a high-quality transmission and/or distribution with reduced complexity, particularly at the receiving end. <IMAGE>

Title: Welding together long strips of sheet metal - by displacing strips transversely to form butt or slightly overlapping joint and passing to welding machine
Inventor: GUELDENPFENNIG WOLFGANG DIPL I
IPC: B23K26/08
Filed: 1992-05-09
Abstract: The method concerns joining of long sheet metal strips (1,3) along their longitudinal edge. The strips - before passing through a welding machine (7) - are displaced transversely to form a butt or slightly overlapping joint. The deviations of the edges from the ideal welding position are measured before welding, and compensating motions are applied to reduce the deviations. To produce such compensating motions, one or more strips are heated or cooled with different intensities, dependent on the magnitude and direction of the deviations.. The installation includes heating (16) and cooling (17) units, as well as a measuring devices (12,13) friction drives (10,11) with transverse movement, and a control unit coupled to a computer. The drives for lateral strip movement are pref. connected to the control unit. Any known measuring device suitable for determining the position of the strip edge can be used. For example, a light beamed from one side of the strips is directed into a diode cell camera located on the other side. Distance or thickness sensors can be used to determine the deg. of joint overlapping. USE/ADVANTAGE - In sheet metal prodn. and prods. industries. In comparison with known procedures, it better solves the problem brought about by strip edge deviations from a straight line.

Filed: 1992-06-26
Abstract: A cosmetic is disclosed for aiding the transport of oxygen in the skin, as well as a process for preparing the same and its use. The problem with known cosmetics is the insufficient oxygen supply to the skin and adjacent tissues. The object of the invention provides a means to go beyond the stratum corneum of the skin and the epiderm by penetration processes in order to increase the oxygen concentration in the corial zone and adjacent tissues and to activate the metabolic processes. For that purpose, a cosmetic with asymmetrical lamellary aggregates consists of phospholipids and an oxygen-loaded fluorocarbon compound or a fluorocarbon compound mixture. The proportion of fluorocarbon compound lies in a range from 0.2 to 100 % by weight/volume, and it is contained in an excipient appropriate for dermatological uses. This cosmetic is prepared by emulsifying its components and is used in salves, creams, lotions, liquids, alcoholic extracts, pastes, powders, gels, tinctures on or plasters and bandages, or in a spray.
