The disclosure is of a transportation system which includes an elongated guidebeam having three spaced apart running surfaces. Two of the running surfaces are substantially vertical to accommodate wheels rotating about vertical axes and the third running surface is substantially horizontal to accommodate wheels rotating on horizontal axes. Wheels which rotate on a vertical axis and wheels which rotate on a horizontal axis are connected to a rack which is adapted to move along the running surface...

An aquarium of transparent material and of prismatic shape, provided with a vertical elongated lamp or lamps adjacent a rear corner, with an opaque shield between the lamps and the corner. Light rays from the lamps enter the aquarium through its walls and are refracted and dispersed, leaving the front wall in dispersed spectral form, thereby providing unusual prismatic rainbow effects. Because of the angular relationship between the walls, internal reflection effects are also provided, multiplyi...

A glycol-pentaborate electrolyte, such as those commonly employed in photoflash capacitors, is improved by the addition of 0.0025-0.006 percent chromium ions thereto in the form of Cr0.sub.3. The addition of said chromium ions increases the breakdown voltage therein, and practically eliminates breakdowns during the aging process.

A process for the separation of xylene isomers which process employs a type X or type Y structured crystalline aluminosilicate adsorbent to selectively adsorb one of the isomers. Adsorbents included are the type X structured and type Y structured zeolites which contain any number of selected cations including Group IA and Group IIA metals. The operations involved are fluid-solid contacting operations in which the particular improvement resides in the use of a two-stage desorption step in which a...

A head and face protective enclosure for use by those working in contaminated environments. An inlet fitting for admitting respiration air to the enclosure located at the rear of the enclosure. A rearward extending air inlet projection that has a bottom wall formed with an opening for the air inlet fitting. The opening is positioned inside of the edge of the bottom wall so that the fitting is protected by the walls of the air inlet projection from impact by falling objects.

This invention relates to an igniter plug adapted for continuous sparking operation for extended periods of time at temperatures as high as about 2,000.degree. F. wherein the shell body constituting the ground electrode is provided with a ductile iridium metal insert ring having high oxidation and spark erosion resistance, the insert being positioned in the spark gap area and being either electron or laser beam welded to the shell in order to produce a narrow weld zone of well-alloyed material w...

An electrolytic capacitor is provided with improved sealing means comprising an adhesive seal between the primary, elastomeric seal and the secondary, hermetic glass-to-metal seal to prevent reaction between the electrolyte and exposed metallic portions adjacent the glass-to-metal seal.

Tire construction featuring as the principal reinforcement a combination of chopped bundles or cords, each composed of an assembled plurality of glass filaments held together, and chopped discrete glass filaments distributed throughout the rubbery matrix generally uniformly, preferably at a level of about two to about thirty-five parts of glass per one hundred parts of rubber and preferably with the bundles exceeding the discrete filaments in amount on a weight basis.

An arcuate housing defining a plenum with a valve for attaching a source of air under pressure thereto and jets in communication with said plenum forming a plurality of jets of air and directing the jets of air so they will enter the space between the bead of a tire and the upper rim when the housing is coaxially positioned adjacent the rim. The high velocity jets of air raise the pressure within the tire quickly to a value sufficient to seat the bead on the rim while the jets compose substantia...

Pallet made of wood members comprising upper and lower decks separated by side stringers and held together by adhesively bonded miter joints.
