Abstract: ABSTRACT OF DISCLOSURE         Method and apparatus are disclosed for filling open-top containers with material capable of flowing such as liquid while preventing contamination of the container exteriors by liquid overflow.  The containers are advanced along a predetermined path.  The liquid is discharged towards the open tops of the containers to be filled in a sub-stantially continuous sheet, descending adjacent the predetermined path.  The containers are advanced beneath the liquid sheet with the containers tilted at a predetermined angle to a vertical.  The tilted containers are overfilled and the overflowing liquid leaves the tops of the containers generally at the tilted lower top portions thereof.  Streams of air are directed towards the tilted containers below the open tops thereof to cause the air to pass around the peripheries of the containers adjacent the container tops.          The air flow prevents the liquid from escaping the open tops of the containers except substantially at the lower tilted top portions thereof, where the air flow causes overflowing liquid to be deflected away from the sides of the containers.          The exterior of each container is thereby kept free of liquid.

Abstract: Abstract A table surface member is movable between a vertical storage position against a wall and a usable position  horizon-tally extending from the wall.  The table member connects to the wall by means of a hinge assembly which permits folding of the table with the underside of the table folding against the wall in the storage position.  The preferred hinge assembly includes upper and lower hinge arms pivotally connecting the wall and the table.  The pivotal connection of the lower arm to the table is offset below a plane passing through the pivot axis of the upper arms to the table and parallel with the table surface.  This offset plus intentional length mismatching of the hinge arms pro-vides an overcenter resistance force which holds the table in its storage position without the need for a separate latch or counter-balance. In a preferred embodiment latch means are provided for latching the edge of the table to the wall or wall mounting brack-et in the usable position, so that no supporting legs for the outer end of the table are required.

Abstract: Abstract of the Invention A case-packing apparatus for assembling packages or trays of fragile objects, such as eggs or fruit, into layer arrays, assemblying the layer arrays into case filling stacks, and depositing the stacks into cases.  Packages or trays are transported  by a conveyor to a transfer plate on which they are assembled in layer arrays that the transfer plate lifts from the conveyor and deposits sequentially on superposed pairs of opposed retractable support ledges on the opposite inner sides of an adjacent vertically movable stacking cabinet.  When a set number of layer arrays has been assembled in the cabinet, the support ledges are retracted sequentially, uppermost first, to cumulatively lower the layer arrays into a solid stack form and lastly to lower the solid stack onto a pair of opposed flexible aprons extending horizontally from the sides of the cabinet under the stack and held taut by bowed flat springs each attached at one end to the corresponding cabinet wall below the upper reach of the extended apron and enveloped by the extended outer reaches of the apron.          The aprons are formed of flexible sheet material that is wound in rolls supported on the cabinet for unwinding and winding exten-sion and contraction of the aprons, with unwinding permitting the aprons and springs to move downwardly into a case therebelow and thereby gently lowering the supported stack into the case.          The apron and spring are straight and flat when fully extended to permit handling of case filling size stacks with easy retraction of the aprons and springs from between the stacks and case walls.          A stack stabilizing plate acts on the top of the uppermost array of packages or trays during the stack assemblying lowering of the layer arrays.  For reorientation of trays or other layer arrange-ments when desired for proper stack assembly, a pair of conveyor belts are used for transporting and one belt is driven while the other is stopped to effect pivoting of the layer arrangement thereon, with an elevating cam under the driven belt enhancing the friction of layer engagement by the belt to assure proper pivoting reorientation.

Abstract: CONTROL VALVE HAVING REDUCED CRACK-OPEN PRESSURE     Abstract of the  Disclosure A control valve having relay and proportioning pistons  has an intermediate piston which controls air pressure access to a blind flow chamber.  At a relatively low value of control air pressure, the intermediate piston is shuttled into a position which closes add traps the existing value of control air pressure in the blind flow chamber.  The trapped constant value of air pressure in the blind flow chamber operates on a larger area piston whose force is added to the forces derived from further increases in control air pressure to provide a first region of output air pressure having incremental increases smaller than the input.  When the input air pressure reaches a certain value, a second region of output air pressure is reached where further increases in input air pressure cause metered addition to the air pressure in the blind flow chamber and thus produces incremental output increases greater than incremental input increases.  At a high value of input air pressure, a third region is reached in which output and input air pressures become and remain equal.

Abstract: ABSTRACT OF THE DISCLOSURE        AUTOMATIC SYSTEM AND METHOD FOR TESTING MARINE    STREAMERS OF SEISMIC EXPLORATION SYSTEMS     In accordance with the present invention, a marine streamer test system and method (MARSTEST) is disclosed for testing field-worthiness of hydrophone sections within the streamer under both passive and dynamic operating conditions.  With regard to a passive operating state, five (5) test parameters are automatically generated and compared with upper and lower limits stored within a mini-computer housed aboard the marine exploration boat.  Any out-of-specification values trip an alarm network and a printer to warn of the malfunctioning streamer section.  Result:  replacement or other repair can be effected.          With regard to dynamic operating conditions, acceptable "signature" characteristics of the streamer (such characteristics can be 2 or more of the above 5 parameters) are stored within the computer aboard the exploration boat and are compared with actually generated field parameter values acquired during operations, say between "shots", i.e., between the sequential activation of the seismic source used in the generation of the seismic data.  Result:  any seismic data acquired by the suspect hydrophone section can be properly inter-preted in view of the malfunctioning state of that section.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a power generating system which includes a wind turbine driven source of energy.  The wind turbine has a wind driven rotor with a plurality of variable pitch blades, and a control for minimizing mechanical stresses in the system during rapid angular momentum changes of the rotor such as during start-up and shut-down.  In accordance with the invention, the generating system includes a sensor for sensing the rotational speed of the system and for producing a first signal indicative of the rotational speed.  A second sensor senses the velocity of the wind driving the rotor and produces a second signal indicative of the velocity.  A scheduler receives the first and second signals and produces, as a function of these signals, a desired blade pitch angle signal.  A controller for the blade pitch angle receives the desired blade pitch angle signal and, in response to this signal, regulates the pitch angle of the rotor blades.  The controller includes an angle measurer for measuring the actual pitch angle of the rotor blades and producing a third signal indicative of the pitch angle.  A comparator compares the desired blade pitch angle signal with the actual blade pitch angle signal and produces a blade pitch angle error signal.  An actuator, which is responsive to the error signal, regulates the blade pitch angle.
