Patent DE-3334208-A1 (DE)
Title: Ketocarboxylic acid esters and their use in cosmetics
Inventor: KRAUSE HORST-JUERGEN DR
IPC: A61K8/37
Filed: 1983-09-22
Abstract: Suitable oil or fat components for cosmetic and pharmaceutical preparations are novel 3-oxocarboxylic acid esters of the general formula  R-CH2-CO-CHR-CO2-R', in which R represents alkyl or alkenyl radicals having 4-16 C atoms and R' represents alkyl or alkenyl radicals having 8-28 C atoms. Particularly useful compounds are those esters which have been prepared from fatty alcohol mixtures, and those which contain at least 25 mol % of C = C double bonds in R and/or R'. They are prepared by transesterification of a corresponding condensation product of 2 mol of fatty acid methyl ester with long-chain primary alcohols, preferably alcohol mixtures, without the use of a solvent.

Title: Packaging machine
Inventor: AMERES JOSEF
IPC: B31B100/00
Filed: 1983-12-12
Abstract: The packaging machine comprises a grouping station, an erecting station for folding boxes and, if necessary, a sealing station. A supply magazine (54) for the folding boxes, a pivotable and displaceable arm (86) for erecting the folding boxes and a transporting device (56) for transporting the folding boxes to the sealing station are arranged on a frame (52) at the erecting station (50). The arm (86), which has a vacuum device (90) at its free end, is articulated with a frame (84) at its rear end, which frame (84) is articulated in its turn via joints (80, 82) with a horizontally displaceable plate (78). To erect a folding box, the arm (86) pivots upwards and sucks up the folding box arranged at the front of the supply magazine. As it is being drawn from the supply magazine, the folding box is partially erected by means of fingers (66) arranged on the supply magazine (54). After the arm is lowered, the folding box comes to rest between a stationary supporting surface (94) and a pivotable supporting surface (100). Turning fingers (96, 110) and a hook (98) fold over 3 floor flaps of the folding box. In this half-closed state, the folding box can then be fed to the grouping station or it can be fully closed immediately by pivoting the frame (84) upwards about the joints (80, 82), the last flap on the ...

Title: Loudspeaker arrangement in electro-acoustic systems in churches and similar spaces
Inventor: GLEICHAUF KURT
IPC: E04B1/99
Filed: 1983-12-20
Abstract: To reduce room echo in churches and similar spaces, the loudspeakers are installed in the pews or other seats in such a way that the main direction of sound radiation passes from the front part of the seat to the listener. An extremely short distance to the listener results from this arrangement; the volume of the built-in loudspeakers can now be kept substantially lower. Thus, the interfering effects of room echo, which reduce the clarity and intelligibility of the sound pattern, are no longer evident. The physical arrangement of the loudspeakers in a channel with slit-shaped sound outlet apertures causes the sound to be radiated over a wider area. The sound outlet openings on the loudspeaker base are closed in order to improve low-frequency response.

Title: Method for mounting and/or sealing an element on a carrier part
Inventor: MURRAY JAMES ALEXANDER
IPC: F28F9/16
Filed: 1984-01-24
Abstract: A hollow element (10), for example a tube, is mounted and/or sealed on a carrier part (12), for example a tube plate of a heat exchanger, by firstly constructing in the carrier part (12) an opening (11) which has ducts (15) in its side wall. After insertion into this opening (11), the element (10) is widened in order to bring its outer surface (13) into close contact with the side wall of the opening (11), with the exception of the points at which the ducts (15) are provided. Thereafter, a flowable mounting/sealing means is applied to the lateral surface of the carrier part (12), with respect to which the ducts (15) are open, and caused to flow, entering the ducts (15) at least partially by capillary action (Fig. 2).

Title: Device for pivoting the yarn guides on ring spinning and ring twisting machines
Inventor: GEISLER HARALD
IPC: D01H13/04
Filed: 1984-04-28

Title: Process and apparatus for demineralising, in particular desalting water
Inventor: BOERS MANFRED KARL-HEINZ
IPC: C02F1/14
Filed: 1984-11-05
Abstract: The invention relates to a process and a plant for desalting/demineralising water. The vapour phase (3) available over an amount of water (1) is passed via a chimney system (8) from the height (G) to the height (H), the transport being effected by the chimney draught (4). By transporting the vapour phase to a height, its relative humidity is increased so that a condensation proceeds or can be carried out. The condensate is collected in elevated condensate stations (5) and can then be distributed on wide surface areas via a distributor system (18) utilising the pressure head (P) obtained. <IMAGE>

Title: Advertising ticket
Inventor: FRIESE PAUL
IPC: G09F1/02
Filed: 1984-11-22
Abstract: The features of the information-bearing advertising ticket invention are depicted such that the normally empty rear side of travel tickets of all kinds are provided with advertisements corresponding to the size of the ticket. If appropriate, the advertiser provides his approved advertisements on the blank ticket himself, or by means of machines provided for this purpose, or has them applied by stamping. The German railway does not incur any costs as a result of this process because the tickets are distributed to passengers anyway. As is right and proper, all preliminary costs and the advertising costs to be paid at the ticket counter or the like are thus charged to the advertiser.
