Abstract: In a known method of immunodiffusion, a sample containing a first agent such as an antigen is introduced into a well in a lamina of agarose gel containing a second agent such as a complementary antibody. The first agent diffuses through the gel and becomes releasably bound to the second agent and, when the concentrations of agents are optimal, the agents form an extended matrix incorporating light-scattering aggregates. The size of the visible matrix enables the concentration of one of the agents to be assessed when that of the other agent is known. Each aggregate comprises very large numbers of the molecules of the agents. The invention provides an improved method in which the second agent is attached to carrier means in the gel (3) so that the carrier means constitutes part of the visible aggregations. The carrier means may constitute the gel itself and/or it may constitute particulate material such as polystyrene particles.

Abstract: Production en continu de fromage blanc de type ''cottage cheese'' à partir de lait ultrafiltré, et préférablement, de lait écrémé. Le lait est soumis à un traitement par la chaleur et il est, éventuellement, préacidifié avant d'être ultrafiltré pour en arriver au contenu solide recherché au niveau de la phase finale de grains de fromage, à savoir 18,5-21 % en poids. Le reste est soumis à un autre traitement par la chaleur, il est ensuite ajouté et mélangé soit à une delta-lactone de l'acide gluconique (GDL) dans une proportion permettant d'obtenir une valeur finale de pH de 4,2-4,7, soit à une culture bactérienne thermophile. En cas d'acidification par le GDL, le mélange est immédiatement placé dans un coagulant. Si l'on emploie une culture bactérienne d'acide lactique, on maintient le mélange à 36-42°C jusqu'à ce qu'on obtienne une valeur de pH redescendue à 5,4, avant de la placer dans le coagulant. Eventuellement, on peut, dans les deux cas, ajouter une faible quantité de présure avant la mise en place dans le coagulant. Le coagulant est maintenu à une température de 25-35° lorsqu'un mélange a été ajouté le GDL, et à une température de 36-42° lorsqu'on a ajouté au mélange une culture bactérienne d'acide lactique; et la caillebotte obtenue avec un pH de 4,2-4,7 que le coagulant a pressé est divisée en grains. Les grains de fromage peuvent être directement versés dans une base de crème pour faire du fromage blanc ''cottage cheese'', ou encore recevoir un traitement ultérieur par la chaleur, le filtrage par l'ultrafiltration et le lavage à l'eau froide avant d'être mélangés à une base de crème.

Abstract: Thin thin film transistor comprises source and drain regions, (2,3) a channel forming region (1) formed between the source and drain regions (2,3), a first (main) gate (51) for turning on or off the transistor and in particular at least one second (sub-) gate (52) for reducing turn-off leakage current. When the n- channel transistor is turned off, for example, a negative voltage is applied to the main gate (51) to form a p channel layer in the channel forming region (1) under the main gate (51) and a positive voltage is applied to the subgate (52) to form an n channel layer in the channel forming region (1) under the subgate (52), for instance, so that a pn junction can be formed between under the main gate (51) and the subgate (52) to reduce the turn-off leakage current. The above-mentioned disclosure can be clearly applied to p-channel transistors. Further, the above four-termfinal transistor can be simply modified to a three-terminal transistor by connecting the main gate to the subgate via a diode or a capacitor or by directly connecting the drain region to the subgate. Further, the above three-terminal transistor can be manufactured in accordance with only the ordinary device manufacturing process.

Abstract: An overhead conveyor with a device for accumulating the trolleys is proposed, which can accumulate with the same space requirement several times as many trolleys in relation to conventional accumulation devices. To this end, the accumulation device (III) is formed from two lines (I, II) guided in parallel at a distance from one another and at least one of these lines (I) consists of a driven continuously revolving conveyor belt (1). On these two lines, the previously separately driven trolleys (20) can roll out. After the excess kinetic energy inherent in the trolleys has been converted, the trolley is drawn in the transport direction (T) via the static friction forming between the roller (4) and the conveyor belt (1) of the line (I), until the trolley (20) runs up against a stop (17) provided for accumulation or a trolley standing in front of it. When the trolley can no longer be transported further, the roller (4), via which the trolley (20) was previously drawn, is set in turning movement. By virtue of the design of the accumulation device (III), it is possible with the same horizontal space requirement as in conventional accumulation devices to accumulate a large number of trolleys behind one another. <IMAGE>
