Abstract: A suitcase has a retractable pull handle. The suitcase includes parallel front and back panels and a wall member which combine to define an enclosed volume. A rigid pull handle is mounted in juxtaposition to the top portion of the wall member. Rollers are mounted on the bottom portion of the wall member opposite the pull handle. The pull handle is extendable to pulling position extending generally parallel to the front and back panels. In the extended position, the pull handle is operable to enable a user to roll the suitcase across a surface on the rollers with the weight of the suitcase being distributed between the rollers and the pull handle. The pull handle is retractable into the inside of the suitcase when not in use. In the retracted position, the gripping member of the pull handle is received into a handle receptacle recessed into the top portion of the wall member. A closure secures the pull handle inside the handle receptacle to prevent accidental extension of the pull handle.

Abstract: The application discloses a continuous flow steam condensate removal device for use in a steam condensate removal system of a type which includes a steam condensate line, a Y-strainer for removing debris from the steam condensate line, and a condensate return line. The condensate removal device is an elongated unitary one-piece body having an entrance end, an entrance passageway, an intermediate passageway, an exit passageway, and an exit end. The intermediate passageway includes a cylindrical venturi tube, which is adjacent an exit of the entrance passageway, and a downstream cylindrical discharge-transition passageway which is adjacent an exit of the venturi tube. The downstream cylindrical discharge-transition passageway has a diameter larger than a diameter of the venturi tube and a length larger than a length of the venturi tube.

Abstract: The centrifugal force drive machine for generating force in a controlled direction is provided. The machine includes a machine frame having a shaft mounted thereto for rotation about its axis. The drive mechanism is provided to rotate the shaft about its axis. At least one mass is mounted on the shaft for rotation therewith. Each mass has a center of gravity which is moveable radially with respect to the shaft between the position in which the mass is rotationally balanced about the shaft and a position in which the mass is unbalanced. A control member in an operative connection between the mass and the frame is provided to constrain radial movement of the mass between the balanced position and the unbalanced position during each revolution thereof. When a mass is in the unbalanced position, the centrifugal force generated by the rotation of the mass is transmitted to the control member, thereby generating a linear force in the controlled direction.

Abstract: The application discloses a cutter member for use in a scrap reduction mill of the type which includes a rotating vertical shaft in a tapered shell. The cutter member is a unitary planar structure carrying cutter assemblies and having a central opening sized to fit and surround the shaft.

Abstract: A fuel supply control for an internal combustion engine designed to run on gaseous fuel (LPG or CNG) utilizes a feedback loop from a lambda sensor in the exhaust gases to a moving coil (82) mounted on a diaphragm (34) of a diaphragm-actuated valve (24) controlling the flow of gaseous fuel to the engine. The coil (82) is similar to the speaker coil of an audio speaker, and moves concentrically of a fixed permanent ring magnet (86) to impart a variable bias on the diaphragm(34) in accordance with the oxygen content of the exhaust gas stream as sensed by the lambda sensor, to control the fuel or air-and-fuel supply to the engine in accordance with desired engine operation parameters. The control has a sufficiently rapid and positive response that it can maintain the free oxygen content in the exhaust gases at substantially 2% for continuous operation of a catalytic exhaust purifier at or nearly at optimum efficiency.

Abstract: The specification discloses pollution control equipment for pollution generating industrial processes. A containment structure confines pollutants within the structure from which they are removed by cleaning equipment. An absorption refrigeration system removes heat from containment structure for co-generation.

Abstract: A suitcase having a pull handle. The pull handle is rotatably affixed to the suitcase with a bracket means to assist the user of the suitcase in pulling same across a flat surface in upright position.

Abstract: An adjustable golf club is provided having an elongated handle which is secured to a club head support, the club head support being pivotally secured to a club head. The club head has a planar striking face and a bottom surface. The pivotal axis at which the club head and the club head support are connected is perpendicular to the striking face. The pivotal connection permits the angular orientation between the handle and the bottom surface of the club head to be varied within a plane that is generally parallel to the striking face. A detent engaging the club head and club head support maintains the desired angular orientation between the handle and the bottom surface of the club head.

Abstract: Use of a mass flow cock with control units and pressure reducing systems results in an even output at changing exit dimensions respectively nozzle exit bores by an automatic balancing of the process volumes, reduces thereby the equipment expenditure and increases the maintenance intervals. This mass flow cock operates using a large pressure difference and an exact adjustment of a special cock piece at two diaphragms.

Abstract: An advertisement display device for use on the handle of a shopping cart is provided. The device has a versatile display area on which a set of inner advertisement frames and one larger, outer advertisement frame are located. Advertisement sheets may be removably mounted in the frames. Fastening members are provided for clamping the multipiece device onto the handle of an existing shopping cart without disturbing the handle.

Abstract: By means of an extended nozzle head having several excentrical nozzle receptions although the cutting oxygen is in line with the cutting jet bores, rotation of the nozzle head or of the total lower part of the burner can bring the working cutting nozzle into correspondence with a determined cutting line; being manifold equipped the thickness of a sample slice can be between two cutting nozzles selected by rotation or a spare nozzle can be put into operation quickly in case of breakdown. The nozzles for sample cutting or replacement are covered behind a protection plate against splash and flames. The protection plate can serve as well as a guide for a save pilot flame. The flexible connection of the adjustable burner and its gas supply is performed by metallic piping accordingly shaped and dimensioned.

Abstract: A water turbine is shown having a water transition member in the form of a partial cone which is positioned on the downstream side of the turbine runner. The cone is mounted independently of rotation of the turbine member and may be rotated by a motor. The partial cone may have ridges or blades which may be retractable.

Abstract: A method and apparatus for conducting exploratory procedures is disclosed. The apparatus includes a flexible steerable device which may alternately be stiffened along its entire length or a portion thereof and relaxed in order to effect movement of the device through a subject, such as the gut of a patient. The apparatus preferably comprises a pair of concentric conduits and is used by inserting the device into the subject, at least one of the concentric conduits being stiffenable. One of the conduits may be stiffened, acting as a guide for the other conduit. One conduit may be made flexible to be steered into the subject or follow the path prescribed by the other conduit or the path of least resistance. The device this minimizes the force exerted on the walls of the gut or other containment.

Abstract: An aircraft tire and an associated landing gear apparatus which rotate a wheel of a landing aircraft prior to contact between the wheel and a runway. The tire possesses an array of projections which have a forward face for catching air and which are molded into the tire in at least one channel circling the tire tread on at least one sidewall of the tire. The tire preferably possesses one or more belts underneath those projections situated in channels to protect the integrity of the tire's shape. A landing gear apparatus which may be used in conjunction with the aircraft tire comprises a duct mounted adjacent to the tire which receives air, reroutes it, and releases it into at least some of the forward faces of the projections so as to effect a further forward rotational force on the tire and wheel.
