  • Patent number: 5461791
    Abstract: A method for rotationally positioning a rotor for balancing procedures uses an instrument within a housing that is temporarily mounted to the axial face of a rotor for determining rotational locations with respect to a reference mark located on the rotor. The instrument has a needle indicator which is responsive to gravity, and is mounted such that it can rotate independently of the position of the housing. Tick marks representing degrees are arranged in a circle around the edge of the needle indicator. Two sets of numerical scales are provided, each in a different color, one increasing in a clockwise direction, and the other increasing in a counter clockwise direction. Two arc shaped arrows are provided, one each in the two colors used for the two sets of numerical scales. The color of the arc shaped arrow that points in the direction of incremental rotor rotation indicates that the set of numerical scales printed in the same color should be used for reading the degree of rotation.

  • Patent number: 5460608
    Abstract: A balloon catheter having an outer shaft and an inner shaft in which the inner shaft is constructed to protect itself over its entire length and especially in its most vulnerable areas without adversely effecting its flexibility, trackability, or pushability or the catheter's deflation time. The inner shaft can be reinforced to prevent it from collapsing or breaking throughout its length and also improving the deflation time of the balloon.

  • Patent number: 5459896
    Abstract: Pressure relief for wheelchair patients is improved by use of a relatively higher density foam, such as 2.4 pounds per cubic foot or above and a 25 percent ILD characteristic of at least about 50 pounds, together with independently acting cube shaped segments. The segments have predetermined respective separation and rounded upper edges with a predetermined radius of curvature which is larger about the periphery of the wheelchair pad. A relatively lowered pad thickness of about 3 inches facilitates patient movement onto and off from a wheelchair cushion. A removable covering of laminated materials is stretchable so as to slide over the rounded edges of the segments and down into separations therebetween to maintain independent action of such segments during use with the covering. An upper layer of the covering comprises a base layer of woven fabric of elastic synthetic fibers. A lower layer of the covering comprises a water resistant coating of urethane generally at least about 1 mil thick.

  • Patent number: 5461282
    Abstract: An advanced center post (ACP) gun is provided which is capable of producing either a large orbit or small orbit electron beam. The gun comprises an annular shaped cathode, a control electrode adjacent the cathode, and an annular anode having an opening therethrough. A center post is disposed axially within the center region of the cathode and the control electrode along a center line of the electron gun and interaction region of a microwave device. The anode is shaped in conjunction with the center post to control position of equipotential lines of an electric field provided in an inter-electrode space between the cathode and the anode so that an electron beam emitted by the cathode converges at the anode opening. The control electrode provides electrostatic focusing of the beam to further control the beam convergence. Multiple polepieces provide accurate control of the magnetic field in the interaction region to shape the beam and control the orbit size and velocity spread.

  • Patent number: 5461329
    Abstract: A method and circuitry for sampling periodic amplitude modulations in a nonstationary periodic carrier wave to determine frequencies in the amplitude modulations. The method and circuit are described in terms of an improved motor current signature analysis. The method insures that the sampled data set contains an exact whole number of carrier wave cycles by defining the rate at which samples of motor current data are collected. The circuitry insures that a sampled data set containing stationary carrier waves is recreated from the analog motor current signal containing nonstationary carrier waves by conditioning the actual sampling rate to adjust with the frequency variations in the carrier wave. After the sampled data is transformed to the frequency domain via the Discrete Fourier Transform, the frequency distribution in the discrete spectra of those components due to the carrier wave and its harmonics will be minimized so that signals of interest are more easily analyzed.

  • Patent number: 5461407
    Abstract: Marking apparatus is provided for carrying out the marking of programmed character strings upon brittle surfaces such as glass. The lines forming the characters are generated by a gas entrained stream of abrasive particles which are expressed from the opening of a nozzle located in close adjacency with the surface being marked. Switching of this abrasive particle string between marking and non-marking orientations is carried out by a diversionary flow of gas under pressure which is expressed into the stream at a rate effective to integrate with the abrasive particle and divert the marking stream away from a marking axis. A suction port is provided which removes particles subsequent to marking or having been diverted to a collection location. In one embodiment, the nozzle from which the marking particulate stream is expressed is maneuvered between lifted or retracted positions and marking positions in close adjacency with the surface being marked.

  • Patent number: 5461283
    Abstract: A magnetron transition apparatus is provided which permits transmission of a microwave RF signal between a magnetron and an output waveguide. The transition apparatus is connected to the magnetron and receives the RF signal from the magnetron, while maintaining a substantially vacuum environment therein. The transition apparatus further comprises an RF interface between the substantially vacuum environment and a non-vacuum environment within the output waveguide. The microwave RF signal from the magnetron is transmitted through the transition apparatus into the output waveguide. The transition structure comprises an adapter having a first portion of generally circular cross-section and a second portion of generally rectangular cross-section. A conductive loop electrically connected to an anode structure of the magnetron is disposed within the first portion and inductively couples the RF signal from the magnetron into the transition apparatus.

  • Patent number: 5460058
    Abstract: An apparatus (10) and method are provided for inspecting an air bag module (12) having a deployment door (15). The apparatus (10) includes a plurality of sensors (55), a base structure (52), and a pneumatic motor (56). The base structure (52) supports the air bag module (12). The pneumatic motor (56) moves the base structure (52) relative to the sensors (55), and thus moves the base structure (52) to and from an inspection station. The sensors (55) sense a characteristic of the air bag module (12) when the sensors (55) are actuated. A controller (62) actuates the sensors (55) when the air bag module (12) is supported at the inspection station by the base structure (52). The controller (62) provides an electrical signal in response to the sensing by the sensors (55). The electrical signal provided by the controller (62) indicates the characteristic of the air bag module (12) that is sensed by the sensors (55).
