A disk of joined segments, having a water resistant sheet over the seams of joining, is mounted on a ring around the nozzle, and water tightly sealed against the ring by expandable rings. A circular portion of the disk that is concentric with the central axis of the nozzle is thinner than the central portion of the disk at the central axis of the nozzle, measured in solid cross section. The thinner circular portion is contoured for resistance to stress from pressure of fluid against the disk. Th...

A thrust vectoring structure is provided for VSTOL aircraft having a pressurized gas generator and at least one rearward facing outlet with an opening for discharging pressurized gas from the pressurized gas generator. The thrust vectoring structure has a plurality of horizontal dividers extending between the sides of the opening. A front flap is rotatably mounted adjacent the front edge of the dividers and a rear flap is rotatably mounted adjacent the rear edge of the dividers. The flaps are ro...

A segmented radio-frequency quadrupole accelerator (10) having a top segment (12), a bottom segment (14), a first side segment (16) and a second side segment (18), each segment having an elongated vane portion (20) arranged in diametrically-opposed pairs along a common longitudinal axis. Mounting arms (30) are integrally formed in the outer walls (28) of the vane portion (20), each end of each mounting arm (30) having a mounting surface (32) formed of a projection (34) having a surface (36) and ...

A segmented waveform generator comprising a plurality of ramp generators whose outputs are coupled to and summed in a summing circuit to provide a waveform having a desired harmonic content or shape. The ramp generators are triggered by the rising and falling edges of trigger pulses to provide symmetrical segmented waveforms.

A neon light display comprising seven segment modules of neon light tubes, and/or other segment configuration modules for special use. The neon light tubes comprise a serpentine configuration comprising a multi-row continuous tube. The serpentine configuration provides for improved visibility at night and at great distances. The modules are detachably secured to a housing which protects electric equipment such as transformers, inside a weather resistant structure. The modules are configured for ...

The disclosure shows a seal assembly for use with a rotating shaft. A fixed radially extending annular sealing face is positioned around the shaft. A segmented radial-type seal element also surrounds the shaft and has an outer radial face which is urged against the fixed annular face by a suitable spring. A garter spring surrounds the seal element to urge the inner surface of the seal element in sealing engagement with the rotatable shaft. The outer radial face is at the axial midpoint of the se...

A segmented ship and including a simple and reliable system for joining the cargo section of said ship with the propulsion section thereof. The connection is made by floating a tongue, forming a part of the power unit, into a slot, forming a part of the cargo unit. The connection is then secured by ballasting the power unit and simultaneously deballasting the cargo unit so that the two units wedge securely into place. The two units are then secured in the connected position by means of securing ...

Apparatus is disclosed for making sheet-plastic articles, such as lids for disposable drinking cups, by vacuum forming. The invention provides spacers that fit into the holes in the stripper plate of the apparatus for the purpose of matching the size of the hole closely to that of the die impression. The spacers are flanged and in three segments, the segments being so arranged that two of the segments can be first placed in the hole, their flanges being entered into a groove in the hole, then th...

A segmented geometric structure that when rotated serves as a functional mood-setting device or simply as a static or rotatable object d'art. The structure is comprised of a plurality of spirally formed curvilinear segments that are joined at their respective top and bottom to form a single rigid structure. The structure may take the form of a spheroid, ellipsoid or any other three-dimensional geometric form amenable to a segmented construction. The structure is suspended by means of a suspensio...

A chamber of a peristaltic pump is described wherein a segment of the stator is removed so that said chamber containing the rotor and resilient tube may be stored with the resilient tube not pinched by the eccentric rotor. When the chamber is to be used, a cap is snapped over the chamber which completes the missing segment of the stator and the rotor is engaged to the motor shaft. When the rotor turns in the stator with all segments snapped together, liquid is conducted from inlet to outlet port...
