Abstract:
An aerofoil structure for a rotating blade-row in a casing, the aerofoil structure comprising a suction side, a pressure side and a tip therebetween, wherein at least a portion of the tip comprises a shaped feature provided on a surface of the tip, the shaped feature comprising a convergent portion orientated to reduce a gap between the tip and the casing in a direction from the pressure side to the suction side of the aerofoil structure.
Abstract:
A fully integrated drying or heating system utilizes forced air and electrical heaters. A solid cartridge heater is enclosed within a heater cavity of a block. The block includes a separate air cavity in heat transfer communication with the heater through a solid portion of the block. The blocks are shaped and configured to be used in banks of plural blocks, with the operating controls and all the components of the air distribution system and air heating system fully integrated into a modular package.
Abstract:
A tip-down indicator apparatus, for signaling a strike on a fishing rig, includes a casing for housing a battery, and a normally open circuit disposed within the casing for placement in electrical communication with the battery. When supplied with a battery, the normally open circuit is completable by proximity to a magnetic field. The indicator apparatus further includes an electrically powered signal generator attached to the casing and connected to the normally open circuit for signaling a completed circuit. The signal generator may be a light or a buzzer. In a preferred embodiment thereof, the indicator apparatus further includes a magnet support member connectable in pivotal relation to the casing, a magnet attached to the magnet support member, and means for drawing the magnet and the casing into proximity in response to a fish biting a hook or lure. This first embodiment may include a fishing rig including a base and a rod-reel assembly which is pivotally attachable to the base. In an alternative embodiment which is attachable to a conventional fishing rod, an apparatus includes a magnet adjacent the end of a spring arm, and an eyelet attached to the end of the spring arm near the magnet.
Abstract:
An apparatus and method for implanting within a human or animal body a surgical device which includes a tubular member with outside markings having a removable pointed end member mounted in the front end of the tubular member; a rod member slidably mounted within the tubular member and a removable handle member secured to the rear end of the tubular member. A pair of incision are made in the body adjacent the area in which the surgical device is to be implanted. The assembled device is inserted in one incision until the pointed end protrudes through the second incision. The pointed end member and the hand handle member are then removed. One end of the implantable surgical device is then attached to one end of the rod member which is then withdrawn from the tubular member together with the surgical device until the surgical device is properly positioned in the tissue. Once the rod member and one end of the surgical device has been withdrawn through the tubular member, the surgical device is removed, from the rod member. The surgeon stabilizes the surgical device at the second incision by holding one of the free ends of the surgical device. The tubular member is then withdrawn from the body leaving the surgical device in the desired implanted area.
Abstract:
A catheter for introduction and removal of fluids from a body and tunneling device therefor, the catheter has a body having a first conduit for removing fluid from the body and a second conduit for delivering fluid to the body wherein at least a part of each of the lumens is integrally formed within a first end of the body and extends along side one another. The first conduit extends beyond the second conduit and forms a terminal point of the first end and defines a first opening thereat and the second conduit extends to a point short of the terminal point defining a second opening. A bumper portion is adjacent the second opening extending toward the terminal point. Another part of each the first and the second lumens are disjoined and form part of a second Y-shaped end. The tunneling device has a channel to removably receive the catheter.

Abstract:
A fully integrated drying or heating system for the printing, coating, or painting industries that utilizes forced air and electrical heaters. The method for heating the forced air incorporates a solid cartridge heater within a specially designed air distribution system. The nature of this invention allows the operating controls and all the components of the air distribution system and air heating system to be fully integrated into a singular compact package, thus requiring only a pressurized air source and electrical power means to be supplied to the unit.
Abstract:
A fully integrated drying or heating system utilizes forced air and electrical heaters. A solid cartridge heater is enclosed within a compact air plenum with a circuitous air path arranged within the plenum in heat transfer communication with the heater. The plenums are shaped and configured to be used in banks of plural plenums, with the operating controls and all the components of the air distribution system and air heating system fully integrated into a modular package.
