Abstract: Roller 10 has a cylindrical surface 12 from which project pins 16 inclined at an angle A between 20° and 80° to the tangent to the roller. The pins have a projection length of 0.5 to 2.0 mm and a diameter of 0.2 to 0.8 mm. They are arranged in double rows 14 with 25 to 34 pins to the inch arranged in a spaced staggered relationship in two adjacent lines. Each row is either inclined to a line parallel to the axis of the roller or of sinusoidal form. 
     A film to be fibrillated is advanced over the surface of the rotating roller for an arc length of contact of 30° to 37° with the ratio of the surface speed of the roller to that of the advancing film being between 1.8 to 1 and 2.2 to 1.

Abstract: Un montage destiné à éliminer la dérive ainsi que le pleurage et le papillotement dans un enregistrement sur bande consiste à enregistrer une tonalité de signal de commande dérivée d'une horloge de référence (159) dans un canal de commande spécialisé ou intégrée dans un canal de signal. Le signal de commande, en lecture (151), est comparé à un signal de référence dans un compteur croissant/décroissant (172) et l'écart sert à corriger la vitesse de l'entraînement de la bande. Le signal de tonalité de commande corrigé en dérive est relié à un convertisseur N/A (156) via une temporisation à RAM programmable (154) et une bascule (179). Le signal de commande analogique retardé et le signal de référence sont limités puis reliés à un compteur de comparateur de phase (158) qui est déclenché par le flanc de montée du signal de référence et lu par le flanc de montée du signal de commande élevé au carré pour mesurer le retard entre lesdits signaux sous forme d'un nombre d'échantillons (N) et de sous-échantillons (N) RAM (154). On utilise le retard mesuré pour faire avancer ou retarder l'adresse Lecture (155) par rapport à l'adresse Ecriture dans la temporisation à RAM (154) où une modification unitaire de l'adresse introduite (N) est égale à 20 mus par exemple. Le temps de retard restant (0-19 mus) est connecté à un circuit de retard de phase (178) servant à retarder la sortie de la RAM via la bascule (179) par intervalles d'une microseconde par exemple.

Abstract: An arrangement for recording the video information items of a video representation contains in the transmission path for recording frequency-modulated video information items a frequency modulator arrangement (10) having a control input (28) for control signals (S(Df)) which offset the frequencies allocated to the signal level of the video signal by a specific frequency amount depending on the type of control signal. The frequency is offset in accordance with a specific continuously repetitive program of a program circuit (29). The video information items thus recorded in frequency modulation and offset in frequency from track to track on the helical tracks of a tape-shaped recording carrier (1) do not form any disturbing interference in the scanning video heads (14,15) during the scanning of the helical tracks adjacent to a helical track to be replayed so that this recording method can be used for recording and replaying at very slow tape speed of the tape-shaped recording carrier (1). <IMAGE>

Abstract: 2.1 In a heat recovery boiler for a gas and steam turbine plant, there is risk that, when the output of the gas turbine is reduced, the heat output in the high-temperature zone will fall to a greater extent than in the low-temperature zone. Due to this imbalance in the heat output, there is the risk that the economiser heating surfaces and feed water preheating surfaces may dry out. 2.2 In this regard, the invention provides that the economiser heating surfaces (46) are arranged ahead of the low-pressure evaporator heating surfaces (50) in the direction of flow of the gas turbine exhaust gases and are connected on the output side both to the high-pressure evaporator heating surfaces (44) and, via a balance line having a reducing valve (70), to an intermediate-pressure water/steam separator vessel (72) positioned on the upstream steam side of the reheater heating surfaces (40). <IMAGE>

The preferred embodiment of the invention comprises a dielectric rectilinear adapter ring or platform [10] that intrudes upper and lower surfaces [10a] and [10b]. Four sidebars [12] enclose a central aperture [13]. Each pair of sidebars [12] terminates in a corner junction [14] which protrudes away from central aperture [13]. The sidebars [12] bear rows of conductors [15] which register with high density leads on the periphery of a TAB frame [22] and a printed circuit board [30]. Each corner junction [14] is designed to include a through-hole [16], which is surrounded by a threaded metal insert [18], and an alignment pin [20]. The platform [10] is a critical element of a novel TAB assembly [21] comprising a TAB frame [22] bearing a chip [24], an elastomer [26], a lid [28], and a PC board [30].

The conductors [15, 36] are deployed in two interleaved rows, one along the edge closest to central aperture [13], and another on the opposite edge. Any adjacent pair of draped conductors [36] is affixed to the top surface [10a] of the adapter [10] so that the lower portions [36b] of the pair are pointed in opposite parallel directions.
