Abstract: For driving a three-phase ventilator motor (1) for the air-conditioning equipment of a railway vehicle, three-phase converters with a constant frequency have been used in the past. In order that there is no draught in the railway vehicle - with a different number of travellers - a three-phase converter is provided, the frequency and voltage of which are regulated by means of a temperature (10) and air humidity sensor (11), namely via a half-wave rectifier bridge (5) which is connected to both of the above-mentioned sensors (10; 11) and which is connected upstream of the three-phase converter. The rectifier bridge (5) is a converter with a converter transformer (2) connected upstream of it in an energy-saving circuit, which is driven with a high frequency and is connected to the on-board power system of the railway vehicle. By this means, it is achieved that the weight of the converter is kept low and, moreover, it has a small space requirement. <IMAGE>

Abstract: A connector for connecting the abutted end portions of two pipes (4,5) comprises a ring (1) having a pair of radially inwardly extending surfaces (2,3) directed towards each other and each for engagement with a radially outwardly extending surface (8,9) on a respective pipe end, the surfaces (8,9) on the pipe ends being directed away from the respective pipe ends. The connector includes operating means (12) for causing radial expansion of the ring to disengage the ring from one of the pipes (5), the ring remaining engaged with the other pipe (4). To this end the corresponding surfaces (2,8) on the ring and the pipe (4) have a greater radial extent than the surfaces (3,9) so that these surfaces remain engaged for all conditions of use of the connector. The connector is particularly suited for connecting the pipe sections of a pipe string for use in the drilling and/or completion of offshore oil or gas wells.

Abstract: A method of producing a cosmetic product containing an integrally molded powder cake. The product includes a casing 2 having an open top enclosed by a cover 3, and the casing defines a cavity 8 to contain the powder cake 10. In fabricating the product, the cover 3 is closed and the casing 2 is inverted and a slurry composed of an inert powdered material, a fatty alcohol and a vaporizable siloxane is introduced into the cavity 8 through an opening in the bottom of the casing. On cooling, the slurry is solidified to form a cake, and subsequently the cake is dried to evaporate the siloxane carrier. The opening in the bottom of the casing can be enclosed by a backing member 12. In an alternative embodiment the powder cake may be molded against a separate surface, such as the face of a purity seal 11, and the cover 3 subsequently closed. The cake may be molded against a surface having a three-dimensional shape.

Abstract: A television type display unit for use in a viewdata or teletext type system has a control circuit which is arranged to trigger the second of two scans which produce a picture frame such that the lines of the second scan substantially completely overlie the lines of the first scan. This arrangement removes flicker which can occur particularly when characters or graphics are being displayed on conventional displays. The result can be achieved by applying pulses to the output of the integrator of the sync separator 55 by means of a pulse generator 63. The timing of the pulses is such that the second scan overlies the first scan.

Abstract: The joining of pipes, especially large concrete pipes, has heretofore been a comparatively cumbersome procedure necessitating the use of special tools by means of which a pressure has been exerted on the back end of the pipe to push it towards the last of the previously laid pipes. In order to simplify the laying and joining of the pipes, it is proposed that a pipe (1) which is to be joined to the latest laid pipe (2) in the pipe line (3) is placed in alignment in front of the end of the latest laid pipe (2), that an asymmetrical two-legged lifting strap (10, 11) is used, the shorter leg (10) of which is attached to that pipe (1), which is to be joined to the latest laid pipe (2) in the pipe line (3), at the end portion which is nearest to the joining end, that the longer leg (11) of the lifting strap is attached to one of the previously laid pipes (2) of the pipe line (3), and that to the point of connection (7) between the legs (10,11) there is connected a hoisting device (15) by means of which a slight vertical heave is effected, resulting in the pipe (1) being pulled in the direction towards the latest laid pipe.

Abstract: The device (1a) (Figure 2) has a longitudinal cutting mechanism (1) and a transverse cutting mechanism (11) for photo-composed films (2). The film is thus cut column-wise and textblock-wise. The longitudinal cutting mechanism (1) has one longitudinal cutter (3) for each column edge corresponding to a defined position in the transverse direction of the film, which cutters can be moved selectively into the actual cutting position. This is controlled by a scanning device which detects markings (8) on the film (2), emits corresponding pulses to a control system (6) which in turn then activates the particular longitudinal cutter (3). In the transverse cutting mechanism (11), transverse cuts can be made in the film (2) in accordance with each textblock (9) up to the adjoining column width. If desired, however, the film can also be completely cut through in this way, so that textblocks (9) cut out by the device (1) as a whole can be removed. In place of a plurality of longitudinal cutters (3) corresponding to the number of columns, it is also possible to provide a single longitudinal cutter (3) in conjunction with a transverse positioning device for adjustment to different numbers and/or widths of columns. <IMAGE>
