Abstract: A method for the continuous production of a purified immunoglobulin preparation wherein the antibodies are substantially enriched by means of a selective two-step ammonium sulfate fractionation procedure employing centrifugation and ion depletion processes. The purified immunoglobulins are subsequently commingled with condensed skim milk and spray dried. The resulting product for example is employed in the formulation of milk replacers for artificial rearing of neonatal pigs to provide the passive immunity to disease normally provided by sows' colostrum and later milk.

Abstract: A method and apparatus for combustion of hydrogen to produce heat, for example to generate steam for power generation. Water is electrolyzed and the hydrogen and a fraction of the oxygen products of electrolysis are passed immediately to a first combustion zone where the immediate combustion of the oxygen products and a function of the hydrogen products is effected. The products from this first combustion zone are immediately passed to a second combustion zone where combustion is again effected with the remaining fraction of the oxygen products of the electrolysis and the remaining hydrogen products from the first combustion zone. The heat generated is thereafter applied to the desired use, for example by passing the products of combustion from the second combustion zone through water to boil the water, the steam thereby produced being used for power generation. Apparatus to carry out this method is also described.

Abstract: A street crossing signal device for blind pedestrians. The device indicates the directions of pedestrian crosswalks at an intersection, so that the blind person can orient himself in a desired direction for crossing the street at one of the crosswalks, and provides a signal to that person when that crosswalk is safe for pedestrian crossing. The device comprises a pair of rigid hand rails secured to a post at the corner of the intersection, each hand rail having at least a portion thereof oriented in the direction of a corresponding crosswalk. The device further comprises a vibrator means which is secured within each hand rail. The vibrator means when actuated causes its associated hand rail to vibrate. Also provided is means to mechanically isolate each hand rail from the post so that vibrations from the hand rails are not transmitted to the post.

Abstract: A miniature pneumatic punch for a strip of photographic print paper, to punch a hole between adjacent photographs at the exposure stage of the printing process. The punch comprises a cylinder body having a chamber and a piston seated within to be pneumatically driven between upper and lower limits in the chamber. For this purpose, actuation and retraction air inlet ports are provided through the wall of the chamber. Fluid communication within the cylinder chamber between the ports is prevented by the piston. An elongated guide of constant cross-section is secured centrally to the piston on the side thereof exposed to the air from the retraction air inlet port. A passageway is provided through the cylinder body below the chamber, the passageway being of constant crosssectional and flushly receiving the guide for sliding movement therein. An elongated punch of the same or less crosssection dimension than the guide is centrally secured to the free end of the guide.

Abstract: A weighing and supporting device for liquid container kegs, such as those for beer. The device comprises a flat, keg-receiving platform beneath which is located a weigh scale, the platform being pivotable between an inclined, dispensing position and a horizontal, weighing position. In the latter, the platform rests upon the scale and is free to move up and down on that scale to enable the platform and a keg supported thereon to be weighed. By taking periodic measurements of the weight of the keg supported on such a device, the need for a liquid metering device in the line of liquid flow from the keg is avoided.

Abstract: A system whereby use is made of a double bottom tank, in fluid communication with a bag made of reinforced elastomeric material to provide segregated ballast space in the cargo space of a ship. The double bottom space and bag are filled with ballast water when the cargo space is empty, thereby making use of the cargo space in which the bag is located to carry ballast water in space previously occupied by cargo, without having any cross-contamination of the ballast water by the cargo residues or gases. The outward and upward movement of the bag is restricted by a rigid guide cage. An open, or partially open, topped rigid container is placed around the guide cage to restrict the "free surface effect" of the ballast water in the unlikely event of failure of the ballast bag. A header tank is provided to keep a positive pressure head on the water in the bag when in the ballast condition. A semi-flexible float assists in guiding the bag during ballasting and de-ballasting operations.
