Abstract: A culture blending vessel adapted for the preparation and containment of samples for microbiological analysis which includes a vessel body and a rotor assembly. The mouth opening of the vessel body is closed by a lid which threads onto the top of the vessel. The rotor assembly has a rotatable shaft extending through a port in the cylindrical side wall of the vessel body. Blending knives are fastened to the interior end of the shaft and may be used to blend the contents of the container by coupling the exterior end of the shaft to a blending motor. The blended sample may then be incubated without transfer to a separate culture vessel.

Abstract: A circuit for starting, operating and instant hot restarting of high intensity gaseous discharge lamps utilizes a conventional ballast, an ignition transformer and a pulse transformer. The ignition transformer is connected across the ballast output and is in circuit with a storage capacitor and a spark gap device which, in combination, provide high frequency, high voltage pulses to a pulse transformer which is in circuit with the high intensity gasesous discharge lamp. There are means to limit the duration during which the high frequency, high voltage pulses are applied to ignite the lamp and there is a current sensitive timing circuit breaker to protect the lamp and ignition circuit.

The card consists of a film laminate including a transparent core layer of biaxially oriented polymeric film on which is printed the second set of game indicia, which is then coated with adhesive, and laminated with a layer of transparent, grease and oil resistant, polymeric film. The game is played by removing the card or cards from the package and placing it in overlying register with the game board to determine whether that combination is a game winner.

Abstract: A system for handling refuse derived fuel (RDF) devised to make RDF fired power plants practical, that includes a method and apparatus for receiving, storing and discharging, distributing and feeding RDF at the plant that accepts such material for fuel, which has been shredded to a predetermined nominal size and usually has most of the ferrous metals removed therefrom, which system includes a relatively large activated bin for primary surge capacity purposes that initially receives and stores the RDF, to provide a binned quantity of same from which as continuous flow of the RDF can be generated that will result in a pulsation free, steady supply of RDF to the plant furnace or furnaces, for firing the power plant involved, with one or more trains located adjacent the locale of the plant furnace to be fired, each of which includes several metering activated bins that are actuated to supply an underlying vibrating feeder that conveys the RDF to the furnace fuel chute, with the activated metering bins of each tra

Abstract: A promotional game particularly adapted for use in connection with packaged food products, the game including a plurality of specially constructed game cards. Each game card consists of a transparent film laminate on which is imprinted a set of game indicia, which will vary from card to card. The card consists of a film laminate including a core layer of biaxially oriented polymeric film on which is printed the game indicia, which is then coated with adhesive, and laminated with a layer of transparent, grease and oil resistant, polymeric film. The game is played by removing cards from packages and placing them in overlying register with each other to determine whether that combination is a game winner.

Abstract: A bag pad arrangement, and method of making same from tube stock, for bagging a pair of liquid containers, such as containers for carry out for milk shakes, carbonated beverages, and other types of drinks, that are commonly available at fast food outlets, at the point of sale of such products, for easy and effective carry away by the customer, in which the bags of the bag pad are all the same and are incorporated in the pad in congruent relation, with each bag having a bottom fold that is gusseted for flat bottom shaping when open, front and back panels extending between side end seals that extend normally of the bag bottom that are spot welded together at the center of the bag but spaced from the bottom gusset thereof, and that define rectilinear side edgings forming the upper corners of the respective bags that extend to the bag end seals adjacent to but spaced from the bottom gusset thereof, and aligned handle forming openings formed in the bag front and back panels adjacent the upper end of each bag; as i

Abstract: A caster with a constant electrically conductive path defined from the pintle to the surface on which the caster wheels are supported to prevent the build up of static charges which may generate sparks and uncontrolled voltage surges that may damage electronic components or cause combustion in volatile environments.

Abstract: A tube connector used to connect conduits for fluid pressure to pressure testing equipment, the tube connector including a piston slidably disposed within a housing, the piston defining a chamber for containment of a seal which engages the outer periphery of the tube to be tested.

Abstract: A mounting arrangement for fertilizer coulters including a selective locking mechanism whereby, at the option of the operator, the coulter may be permitted to pivot about the coulter supporting shank or be locked in place.

Abstract: A container is provided for the mixing and storage of liquid and liquifiable ingredients which, when full, must be carried from place to place. The container has a constricted neck between an upwardly flared brim and a downwardly flared shoulder section to which is attached a vertically slidable handle assembly arranged to conform to the counters of the container when at rest and to maintain the container in a substantially upright orientation when full to avoid spillage of the contents.

Abstract: A tilt control arrangement for office furniture chairs of the type having a chair seat structure mounted on a supporting base for rearward and forward tilting movement of the chair seat about an essentially horizontal axis extending essentially crosswise of the seat. The tilt control arrangement comprises a bifurcated seat structure mounting member defining a pair of parallel arms for pivotally mounting the seat structure for its tilting movement. Depending from the underside of the chair seat structure 15 a lug that projects below the level of the chair seat tilt axis.
