Abstract: A spray coating apparatus that applies a coating material onto outer surfaces of glass objects includes a coating material source that includes a coating material. A spray nozzle assembly includes a spray nozzle fluidly connected to the coating material source. The spray nozzle is arranged and configured to direct the coating material in a first direction toward the glass object and provide an overspray amount of the coating material by the glass object such that the overspray amount bypasses a non-line of sight area of the glass object. A turn nozzle assembly includes a turn nozzle fluidly connected to a pressurized gas source. The turn nozzle is arranged and configured to direct pressurized gas in a second direction different than the first direction toward the non-line of sight area of the glass package to redirect the coating material onto the non-line of sight area.

Abstract: An optical fiber draw furnace muffle includes a body portion defining a substantially cylindrical cavity extending along a centerline axis of the muffle. A tapered portion has an interior surface which defines a first curved portion with a first radius of curvature and a second curved portion with a second radius of curvature. At least one of the first and second radii of curvature has a radius greater than a radius of the cylindrical cavity.

Abstract: An apparatus including a first substrate, a second substrate, an inorganic film provided between the first substrate and the second substrate and in contact with both the first substrate and the second substrate, a laser welded zone formed between the first and second substrate by the inorganic film, where the laser welded zone has a heat affected zone (HAZ), where the HAZ is defined as a region in which ?HAZ is at least 1 MPa higher than average stress in the first substrate and the second substrate, wherein ?HAZ is compressive stress in the HAZ, and wherein the laser welded zone is characterized by its ?interface laser weld>?HAZ, wherein ?interface laser weld is peak value of compressive stress in the laser welded zone.

Abstract: A stationary strength training equipment includes a frame assembly, a lockable bilateral user interface installed on the frame assembly, a balancing structure connected to the lockable bilateral user interface, a plurality of user selectable weights supported by the frame assembly and connected to the balancing structure, a load detecting strain gauge disposed on the user selectable weights to detect a weight of the user selectable weights being lifted, and an informing device connected to the lockable bilateral user interface to detect and show a warning signal to a user. The lockable bilateral user interface further includes a locking mechanism assembly and a central pivot assembly; the balancing structure is able to rotate along the central pivot assembly, and the locking mechanism assembly selectively restricts a rotation of the balancing structure.

Abstract: A stationary exercise equipment has a supporting structure, a movable user interface connected to the supporting structure, and a force-resisting device. The force-resisting device with a hub mounted continuously variable transmission configured therein provides a variable resistance force that varies an amount of force with a movement of the movable user interface. The hub mounted variable transmission is operably to vary the resistance force of the movable user interface in a manner of varying a rotational rate of the user interface to increase or decrease as required.

Abstract: A wide band travelling wave amplifier including an input waveguide coaxia disposed about an interaction waveguide. Both waveguides are tapered with the same direction of increasing cross-section. The interaction waveguide is a high-pass filter while the input waveguide is a low pass filter. The input waveguide is positioned relative to the interaction waveguide so that each cutoff plane in the input waveguide corresponding to a given frequency, .omega..sub.c, is displaced in the direction of increasing cross-section from a cutoff plane in the interaction waveguide corresponding to .omega..sub.c where .omega..sub.c is any frequency in the frequency band of the amplifier. A slot, disposed between the cutoff planes corresponding to .omega..sub.c couples the .omega..sub.c frequency component of an input wave from the input waveguide to the interaction waveguide.

Abstract: A coupling circuit for use at microwave frequencies comprising two conductors each having substantially the shape of a W, which conductors are deposited on a substrate in a manner so that the bases of W's oppose one another to form two semi-lumped capacitances of different susceptance, separated by phasing line lengths.

Abstract: A proximity coupler is provided for high frequency circuits wherein conductors are deposited on a substrate in the shape of a hollow dumbbell intersected by an X. Coupling is provided primarily across sawtoothed shaped gaps in the dumbbell center section and secondarily across a gap formed by spaced parallel connectors in said center section. The parallel conductors have phase delaying loops at opposite ends, and the resulting coupling characteristics of the proximity coupler can be modified by dimensional changes of the loops.
