Abstract: ABSTRACT OF THE DISCLOSURE   The activity of conventional iron-based ammonia synthesis catalysts is enhanced by supplying alkali to the finished catalyst by vapor transpira-tion, either during preparation of the catalyst or during its use in a synthesis operation, or during both.  The catalyst used may contain one or more conventional promoters, including alkali embodied in the catalyst during its manufacture.  The vapor transpiration provides increased effective alkali at the catalyst surfaces in the form of an inorganic compound, such as the hydroxide, carbonate or hydride.  It avoids the problem of loss of surface area which would result from adding more alkali during manufacture of the catalyst.  Vapor transpiration conditions, especially the relative tempera-tures of the vaporization chamber and hence the alkali vapor partial pressure in the catalyst chamber, are controlled to achieve an effective deposition while avoiding pore blockage or reduction of surface area.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to an electro-optical switch for switching optical radiation between two wave guides having a coupling zone. According to the inven-tion, the electrical control means incorporate two pairs of electrodes respectively associated with two guides and positioned so as to cover a variable fraction of the width of the guides. As a result, the electro-optical effects produced and therefore the propagation velocities in the two guides are made variable. As a function of the electrical connection mode of the electrodes, two switch-ing states are obtained with a considerable tolerance for the length of the guides and the control voltage.       The invention is used in optical telecommunications.

Abstract: METHOD AND MEANS FOR DEMAND ACCESSING      AND BROADCAST TRANSMISSION AMONG PORTS           IN A DISTRIBUTED STAR NETWORK                     Abstract A demand access broadcast transmission method and means capable of supporting random port access and any-to-any transmission at very high data rates.        A communication medium formed from an inverted tree network of nodes and full duplex connecting links permits the establishment of a path lock up-link through the network from a demanding port to a root node on a first-come first-serve demand access basis with arbi-tration at each distinct tree node level.  Broadcast transmission is perfected down-link over all fan-out paths from the root node.  Collision is avoided by locking a path to a port and by limiting race condi-tions among active ports to only the leading edges of messages.  Thus, relinquishment of a broadcast channel overlapped with retransmission of a message does not result in path seizure since the occurrence of message leading edges is the singular path connection invoking event.

Abstract: TITLE OF THE INVENTION      Process    for    beneficiating    and    stabilizing coal/oil/water fuels.                    ABSTRACT OF THE INVENTION    A coal slurry containing 10-60% solids by weight is optionally first coarsely ground to about 20-80 mesh. Contaminant matter released thereby, may be separated by conventional means such as froth flotation which would eliminate a large proportion of the ash which is energy consuming as well as abrasive in nature. The "clean slurry" would now have water added back and would be further ground to about 100-300 mesh particle size and would then be cavitated by sonic energy making the particle size even smaller and freeing any remaining contaminants including iron pyrites and ash.  To this, a mixture of oil is added and the coal, oil mixture is then sonified during which process spherical agglomeration of the coal and oil occurs. The agglomerate and water mixture is screened to separate out most of the water leaving behind about 10-40% water in the coal, during which process the contaminants are also discharged with the water.  The spherical agglomerates are mixed with a balance of oil to about .6 times the weight of the coal to produce a stable thixatropic fuel with excellent pipe travel characteristics due to a migration of a thin film of water to the boundry layer between the bore of the pipe and the fuel.  The process including the sonification steps is also useful generally in the separa-tion of solids by agglomeration.

Abstract: ABSTRACT OF THE DISCLOSURE           A standardized preparation of intestinal origin is provided herein for the prophylaxis of intestinal disturbances, especially salmon-ella infections, in poultry.  At least two bacterial strains of normal alimentary tract (i.e. intestinal origin) bacterial species are anaero-bically cultivated either separately or together according to known methods, after which the cultivated bacteria are isolated from the nutri-ent medium and finished to a preparation, e.g., by lyophilization.  The cultivation may take place in the presence of epithelial cells from the alimentary tract, for example, the crop of a poult.  The bacterial strains used for the cultivation of the preparation are essentially those whose adhesion efficiency onto the epithelial cells of the alimentary tract of the poult has proved to be at least 10 bacteria per epithelial cell.  In this way improvements are provided in bacterial preparations useful in preventing infection  in young poultry.  In addition, chicks treated with such preparation display an improvement in health and faster growth.

Abstract: ABSTRACT      A dispensing cap construction for hand-held dispensers, comprising a tubular cap body with a top discharge opening and a closure cap adapted to mount on the cap body by means of a flexible hinge.  The body has an upstanding spout which surrounds the opening and which is arranged to receive a depending pin disposed on the underside of the closure cap.   There are provided on the cap body and closure cap, cooper-able detent means which yieldably hold the closure cap in an assembled, sealing position.  The length of the pin on the closure cap is sufficiently great such that engagement with a guide wall portion of the spout occurs prior to the engagement of the detent means.  The advantage of the pre-sent construction over the devices of the prior art is that proper alignment and centering of the cap on the body is more easily attained, facilitating proper closing of the dispenser.  In addition, the length of the pin is such that it extends a substantial distance past the surrounding wall adjacent the discharge opening, thereby tending to break up accumulated product and preventing any residue from hardening over the opening and blocking the same.
