Abstract: X-ray film feeding magazine usable in a film handling automatic apparatus, comprising a tray (3) in which is defined a housing (26) to receive an x-ray film packet (F). The film housing is delimited by a front gauge (17) and at least a side gauge (28) which can be shifted between a stand-by position and a work position to reduce the housing dimensions to prearranged values. The shifting of said movable front and side gauges from the stand-by to the work position is controlled by means of contrast elements (15) which are associated with the front gauge and accessible from the outside to apply an external thrust to the front and side gauges.

Abstract: In each branch of the transistorised push-pull output stage (1, 2), a sensing element (4, 5) is arranged across which in each case a voltage measured with respect to reference potential can be picked up. These voltages are connected to one input each of a differential amplifier (10). The output voltage is connected to a comparator (13) which compares it with a reference voltage (Uref). The output of the comparator circuit (13) controls an electronic switch (16), in such a manner that it charges an electric store (18) the charging voltage of which controls the quiescent current of the push-pull output stage (1, 2). <IMAGE>

Abstract: Current flow through the base region (3) of a hot charge-carrier transistor is by hot majority charge-carriers (i.e. hot electrons for a hot electron transistor) which are injected into the base region (3) at an emitter-base barrier region (2). This barrier region (2) is doped with impurity of the opposite conductivity type ( p  type for a hot electron transistor) and is sufficiently thin as to form a bulk unipolar diode with an adjacent part of the base region (3). In accordance with the invention, the emitter-base barrier region (2) is of different bandgap semiconductor material (for example, gallium aluminium arsenide) compared with that (for example, gallium arsenide) of the base region (3) so as to form a heterojunction (23). The barrier height ( h ) of this barrier region (2) is determined in part ( h  -  x ) by the opposite-type doping and in part ( x ) by the heterojunction (23) and can be made large so as to increase the energy of the injected charge-carriers and hence the collector efficiency of the transistor. Furthermore the bandgap structure of the different materials can provide a step ( y ) in the minority-carrier band edge (i.e. the valence band edge for a hot electron transistor) which reduces the depth of a potential well for the minority carriers thereby effecting a reduction in the trapping of minority charge-carriers in the barrier region (2) while a desirably high barrier height ( h ) for the majority carrier injection is still obtained.

Abstract: A fuel filler pipe seal (50) includes upper (54) and lower (58) portions and a sealing lip (52) positioned at the juncture of the upper and lower portions to engage an outer surface of a fuel nozzle and prevent the escape into the atmosphere of fuel fumes during a fueling operation. The lip (52) lies in a plane (64) which intersects a groove (68) formed in an outer surface of the seal to receive a seat (30) formed on a mounting bracket (22) mounted in an upper end of the filler pipe (l2), and the upper portion (54) of the seal has an umbrella valve (70) formed integrally with it which covers a vent opening (28) in the bracket and is preloaded to release at a predetermined pressure. By positioning the sealing lip adjacent the seat-receiving groove a better seal with a fuel nozzle is formed, premature release of the umbrella valve is avoided, and damage to the seal when the nozzle is thrust into the filler pipe is minimized.

Abstract: A wobble plate type compressor with a capacity adjusting mechanism is disclosed. The compressor includes a housing (2) having a cylinder block (21) provided with a plurality of cylinders (24) and a crank chamber (23). A piston (13) is slidably fitted within each of the cylinders and is reciprocated by a swash plate mechanism (10,11) driven by a shaft (6). The swash plate has a hinge mechanism (91) for changing its slant angle. The slant angle is controlled by the pressure situation in the crank chamber which in turn is controlled by a control mechanism comprising a passageway between the crank chamber and the suction chamber (40) and including a valve mechanism (17) to control the closing and opening of the passageway. The valve mechanism includes a valve element (177) directly controlling the closing and opening of the passageway, a first valve control device (171), which controls operation of the valve element in response to pressure in the suction chamber, and a second valve control device (175) which controls the predetermined operating point of the first valve control means. The operation of the second valve control means is controlled in response to external control signals.

Abstract: Process and/or system for programming a video-recorder (Fig. 2) with data required for the recording of desired broadcasts, using a televison receiver (Fig. 1) suitable for receiving and replaying videotex signals, whereby the required data can, via a settable marking system, be taken, on instruction, from tables (videotex tables) which have the program annoncements and are transmitted by videotex signals, and can be fed into a program memory (T) of the video recorder. On an instruction the videotex signals allotted to the required data are stored in an intermediate memory of the television receiver and the necessary data are removed immediately or a special instruction from the stored videotex signals and transmitted without wires to the video-recorder where they are stored in the program memory of the video-recorder. Programming of a video-recorder is thus further improved.

Abstract: Un procédé de production de bouteilles plates à un fond plan ou concave par libre extrusion d'un tube en matière plastique comprend le soufflage d'une forme intermédiaire (2) à section transversale circulaire et sa conformation essentiellement mécanique en une bouteille plate, associée à une finition par soufflage pour obtenir des rayons nettement rendus. Il est essentiel de souffler la forme intermédiaire de sorte que sa longueur soit à peu près égale à la hauteur de la bouteille plate, que la circonférence au niveau de son corps soit comprise entre -1 et -10% environ de la circonférence de l'endroit correspondant de la bouteille plate, mais que la circonférence des parois latérales près du fond soit comprise entre 0 et +10% environ de la circonférence de l'endroit correspondant de la bouteille plate. En outre, le rayon de courbure (R) de la zone de transition entre la paroi du corps et le fond est à peu près égal au rayon de courbure de la zone de transition entre la paroi du côté large de la bouteille plate et son fond. La partie du fond qui correspond à l'extrémité comprimée (2a) du tube est séparée par compression pendant le formage. Pour appliquer le procédé, on utilise une machine d'extrusion-soufflage qui comprend un moule de soufflage de la forme définitive composée de deux moitiés dont chacune est formée de deux moules mobiles perpendiculairement au plan de joint du moule. Le premier moule forme le goulot, le côté étroit et le fond de la bouteille plate, le deuxième forme les côtés larges de la bouteille plate.

Abstract: A method for preparing and maintaining an electroless plating bath. Seeded surfaces (14) include a palladium and tin coating which receives plating from an electroless plating bath. The plating bath conditions are maintained by measuring the open circuit potential of the bath with a potentiostat (20). The chemical constituent concentration levels are adjusted to a first open circuit potential for the bath. Air is removed from the bath and the open circuit potential increases to a second level representing a bath chemical activity which produces optimum electroless plating on the seeded surfaces. Parts having seeded surfaces are inserted in the bath and a flow of air is re-established in the bath, rendering less negative the open circuit voltage potential during plating of the parts.
