Abstract: AN ELECTRODEPOSITION   COATING APPARATUS             Abstract of the Disclosure An apparatus used in the electrodeposition coating of a continuous sheet of metal as it travels in a horizontal pathway between a pair of electrically charged electrodes and through a bath of liquid coating solution that is continuously circulated to the bath through a pair of liquid seals which are disposed adjacent opposing, aligned openings through which the sheet of metal enters and exits a chamber containing the bath.  The liquid seals are each comprised of a pair of nozzles for directing con-verging streams of liquid coating solution against the traveling sheet of metal in the direction of the chamber and have a three-fold purpose.  They are designed to, (I) prevent the escape of liquid coating solution from the chamber through the openings, (II) provide a liquid support for the sheet of metal at the openings in the opposing end walls of the chamber, and (III) direct fresh liquid coating solution along the sheet of metal into the critical area or space between the electrodes to main-tain and keep uniform in this area, the concentration of the liquid coating solution that becomes diluted as the coating material of the solution adheres to the sheet of metal during its travel between the electrodes.  A pair of blow off nozzles are supplied adjacent and outside each of the liquid seals to direct air, under pressure, angularly against the sheet of metal in the direction of the chamber to aid in. the prevention of the escape of liquid coating solution from the apparatus, to provide an additional fluid bed for supporting the sheet of metal and to minimize and control the thin film of liquid coating material which adheres by surface tension to the sheet of metal.

Abstract: ABSTRACT           Heretofore gas contained in solution in beverages in sealed containers has been carbon dioxide so that upon opening of the package the carbon dioxide readily comes out of solution and the beverage effervesces to form a head of froth.  By the present invention, however, release of carbon dioxide is expedited by forming a sealed package of the beverage in which the beverage has in solution therewith at least one of the gases selected from the group consisting of an inert gas and carbon dioxide;  opening the sealed package and subjecting the beverage to an excitation medium to an extent and for a time sufficient to cause some of said gas or gases to come out of solution and cause or contribute to the formation of the head of froth.

Abstract: FISH COUNTER WITH SCANNING TRANSDUCER         ABSTRACT OF THE INVENTION     A system for counting fish in a body of water uses one or more acoustic focusing liquid lens transducers each of which includes a large number of individual piezoelectric elements arranged in an arc to create a fan-shaped pattern of adjacent beams, each of which has a narrow beam width.  An electrical counting circuit includes a clock producing a series of timing pulses supplied to a plurality of binary coded decimal (BCD) actuated switch circuits, one of which initiates sequential operation of transmit pulses from individual transducer elements.  Timing of receiver operation is also controlled by said timing pulses after a delay to minimize "ringing" of the transducer elements from the transmit pulses.  Received echo signals are amplified, threshold detected and converted to uniform pulses.  A second BCD actuated switch circuit cooperates with a series of range gates also connected to receive said timing pulses to control the distribution of the uniform echo pulses to one of a series of counters each of which receives and counts pulses from a single transducer element.  Display means connected to the counters makes it possible to read out counts on individual sectors individually or collectively or to print out counts from the counters at specified time intervals. Where a plurality of liquid lens transducers are used, they are connected to the same clock pulses such that they operate in synchro-nism.

Abstract: ABSTRACT OF DISCLOSURE                    This invention relates to an improved coupling for articulated vehicles that reduces or prevents jack-knifing of such vehicles when braking hard or on slippery surfaces.        Jack-knifing usually occurs where all four wheels of the tractor portion of the vehicle lose traction and the whole vehicle skids in a straight line until any slight imbalance in the rolling resistance of the wheels imparts a force to the tractor or trailer having a component normal to the direction of travel causing the vehicle to swing about the point of coupling between the two units into the fully jack-knifed position.  Jack-knifing can also occur where the rear wheels of the tractor portion of the vehicle lose traction.        Any force normal to the direction of travel will in this case cause sudden and serious jack-knifing that is very difficult if not impossible to correct.  The invention comprises a simple releasable coupling between the tractor and trailer of an articulated vehicle which allows articulation of the vehicle but incorporates a braking system that can prevent or inhibit rotation about the point of coupling between the tractor and trailer in circumstances likely to produce jack-knifing.  The braking system of the coupling may be connected to the braking system of the articulated vehicle so that when the braking system of the articulated vehicle is operated the braking system of the coupling is also operated and prevents or inhibits any further jack-knifing of the articulated vehicle. Two pairs of locating members locate the trailer with respect to the tractor and are arranged so as to provide reactive moments of force that oppose any tendency of the trailer to overturn when cornering or travelling on uneven roads.

Abstract: Abstract A first solution of an electrolyte is injected underground into a volume of soil having negative surface charges on its particles.  A cationic surfactant suspended in this solution neutralizes these surface charges of the soil particles within the volume.  Following the first solution, a cationic asphalt emulsion suspended in a second solution is injected into the volume.  The asphalt emulsion diffuses through the volume and electrostatically bonds with additional soil surrounding the volume such that an electrically conductive water repellent shell enclosing the volume is formed.  this shell prevents the leaching of electrolyte from the volume into the additional soil.  The second solution also contains a dissolved deliquescent salt which draws water into the volume prior to the formation of the shell.  When electrically con-nected to an electrical installation such as a power line tower, the volume constitutes a grounding electrode for the tower.
