Abstract: On décrit un appareil servant à disposer de manière feuilletée sur du verre une couche d'une feuille polymère en plastique (52, 60) - telle qu'un polyuréthane ou un polybutyral de vinyle non-orientés feuilleté avec du polytéraphtalate d'éthylène. On prévoit une étampe inférieure (12) présentant essentiellement le même profil que le verre (18) et qui entre en contact avec celui-ci au cours du procédé de feuilletage; et la surface de l'étampe tout au moins présente un coefficient de dilatation et de contraction thermiques sensiblement identiques à celui du verre (18) de sorte qu'il ne se produire pas de glissement significatif du verre par rapport à l'étampe lorsque le verre et la feuille polymère en plastique sont chauffés et refroidis. On peut utiliser une étampe segmentée, laquelle comprend des segments (44) présentant des coefficients de dilatation et de contraction thermiques sensiblement différents de ceux du verre, mais, comme ils sont isolés d'un point de vue spatial, la face de l'étampe ne subit pas de dilatation ou de contraction brutes par rapport à celles du verre. Un bélier de compression (14) s'appuie contre la feuille polymère devant être placée sur le verre. L'étampe et/ou le bélier sont chauffés (24); en général, il s'agit de l'étampe. Le bélier peut comporter une face dure et flexible (32) et un piston extensible (34) qui agit à l'encontre de la face pour assurer le contact intial, au centre du verre, du bélier et de la feuille avec le verre; et, comme le bélier continue à s'appuyer contre la feuille, le piston est enlevé de manière qu'un contact de surface entier soit produit. On décrit des procédés servant à faire fonctionner l'appareil, ainsi que des structures multicouches verre/plastique.

Abstract: In a dynamic logic circuit, an X decoder and a Y decoder receive a more significant bit portion and a less significant bit portion of an internal address generated by a sequencer, respectively. A precharge signal supplied to the X decoder is generated when the sequencer start signal is applied to the sequencer, or when the more significant bit portion of the address supplied to the X decoder changes or is incremented. Therefore, even when the less significant bit portion of the address supplied to the Y decoder changes or is incremented, the precharge signal supplied to the X decoder is not generated if the more significant bit portion of the address supplied to the X decoder does not change. Thus, the number of the precharge/discharge is reduced, and accordingly, the operating current of the dynamic logic circuit is decreased.

Abstract: In an expansion mandrel, in particular a test mandrel, an annular body is pushed over a core (1). In order to provide a large clamping range, conically running grooves (4-6) with a bevel (7) are formed from a tapered section (3) of the core, in which grooves (4-6) one clamping jaw (8-10) each is essentially axially displaceable, the clamping jaw having an axially parallel outer clamping surface (11-13) and an inner, bevelled sliding surface (14) which is adapted to the slope of the bevel (7) of the groove. The clamping jaws (8-10) are held in a radially displaceable manner in an axially movable guide ring (16). Accommodated in the guide ring (16) are profile springs (17) which press the clamping jaws (8-10) against the bevels (7) of the grooves (4-6).

Abstract: The invention relates to a snubber network for a branch pair (36) which consists of two power semiconductors (T1, T2) which can be switched off, said snubber network consisting of an RCD branch-pair snubber circuit (38) which contains two RCD snubber circuits (40, 42). According to the invention, a further diode (D1', D2') is connected electrically in parallel with in each case one resistor (R1, R2) of the RCD snubber circuits (40, 42), in such a manner that the anode of one (D2') of the further diodes is electrically conductively linked to a positive DC voltage connection (48), and the cathode of the other further diode (D1') is electrically conductively linked to a negative DC voltage connection (46) of the branch pair (36). An RCD<2> branch-pair snubber circuit for branch pairs (36) is thus obtained, which branch pairs (36) are used in multi-pulse converter bridge circuits, a pulsating voltage spike on an intermediate-circuit rail (32) being largely prevented. <IMAGE>

Abstract: A conveyor assembly (10) includes an endless conveyor (16) having ends supported by a drive drum/ sprocket (12) and an idler drum/sprocket (14) mounted on respective portions of a split conveyor frame. The frame portions (24, 26) are movable with respect to each other. Dual tensioning cylinders (28, 30) control the movement of the portions and thus the tensioning force acting on the conveyor (10). A hydraulic circuit (40) for the tensioning cylinders (28, 30) provides a first level of tensioning force to said conveyor upon initial start-up of the conveyor apparatus (10) and a second reduced level of tensioning force after a predetermined time. The first level of tensioning force is sufficient to overcome the breakaway friction between the frame portions (24, 26) while the second level of tensioning force is sufficient for proper and sustained tension during normal operation of the conveyor. A time delay control valve (60) in the circuit includes a movable valve element (72) actuable by a differential hydraulic force through a combination of restrictive orifices (81, 82), an accumulator (84), a return spring (68) and operating faces (88).

Abstract: In a colour television camera apparatus, a 2fs-rate luminance signal and fs-rate chrominance signals are selectively generated by a matrix circuit (8), in conformity with a plurality of standard systems, from 2fs-rate three-colour image pick-up signals generated by an image signal pick-up unit (3, 4). The fs-rate chrominance signals are modulated by a modulating circuit (12) into fs-rate modulated chrominance signals which are converted by a rate converter (13) into 2fs-rate modulated chrominance signals. The 2fs-rate luminance signals and the 2fs-rate modulated chrominance signals are combined by an adder (14) into 2fs-rate digital composite video signals which are converted by a D/A converter (15) into analogue composite video signals. In this manner, analogue composite video signals, in which the bandwidth of the luminance signals has been enhanced up to the sampling frequency fs, may be selectively output in conformity with a plurality of standard systems.

Abstract: An imaging apparatus equipped with a path for moving receiver sheets through the apparatus, has infrared sensors (18a, 18b, 18c) situated along said path. If a substantially transparent receiver sheet (15), having coated on at least a portion thereof an infrared absorbing material contained in a polymeric binder, passes along the path, the infrared sensors detect the presence of the infrared absorbing material on the substantially transparent receiver sheet. This process enables the use of substantially transparent receiver sheets in imaging apparatuses employing optical sensors or detectors for locating and/or positioning receiver sheets in the apparatus without the need for opaque strips on the transparencies or separate opaque sheets attached to the transparencies.

Abstract: A method and apparatus for improving the operating efficiency of a boiling water reactor is disclosed. Instead of coolant water being injected simultaneously at the bottom of the fuel rod assemblies and core bypass regions, the two flows then proceeding in parallel to the top of the reactor, the top of the bypass regions is sealed off and bypass coolant water is directed at the bottom of the sealing cover. This forces the bypass coolant water to flow down through the bypass regions. At the bottom of the bypass regions, provision is made to allow the bypass water to flow into the bottom of the fuel rod assemblies where it is entrained by the fuel rod coolant water flow. By converting flow through the core bypass region into a single series flow, increased operating efficiency is achieved.
