Abstract: The present invention is related to a system which comprises a number of transmitting microcells sequentially disposed and integrated along the road. The system developed, the aim of which is helping drivers by supplying them with useful information on the route they shall follow, comprises a number of repeating stations wherein each of them is provided with a “Fi” frequency receiving antenna which is interconnected to a “Fi” frequency transceptor for “FM”, and the latter is interconnected to a 87.9 Mz directional antenna through low loss cables.

Abstract: An UHF antenna system having inner antenna conductor and an outer antenna conductor having end caps. The inner conductor is supported by one of the end caps. This provides an electrical short to the outer antenna conductor and a thermal short to ambient.

Abstract: A flat strip-like radiator is angled along the width of the strip to form radiating arms of predetermined length and angles to radiate a design radiation patter. The flat strip is secured to a ground plane such that the flat strip is perpendicular to the ground plane.

Abstract: An uncontrollable dehydrator where the uncontrollable discharge is augmented with a purge gas to increase the capacity of the dehydrator to achieve a target flow rate and dew point.

Abstract: A slot antenna has a generally cylindrical waveguide and a feed end. A plurality of slots are formed in the waveguide. A plurality of feed strips are secured to the feed end and are secured to the waveguide in spaced apart relationship from the outer surface of the waveguide. Exciters are in communication with the feed strips and extend over the slots.

Abstract: A two component connection system consisting of a female connector and a male connector. The female connector consists of three components joined together with a bolt. First is a cup that has the same inner and outer diameters as the tubing that forms the rest of the inner conductor. Second is a bushing stepped diametrically in three places. The first step accepts a standard anchor insulator. The second step is the same diameter as the outside of the inner conductor tubing. The third step has a diameter that allows it to fit snugly inside of the inner conductor tubing. The male connector consists of a cylinder with a bushing on one end that allows it to be assembled to inner conductor tubing and a diameter on the other end with a tandem pair of glands for watchband style springs that fits inside of the female connector cup. The cup of the female connector is fixed in position relative to the outer conductor by the captured anchor insulator.

Abstract: A capillary membrane gas dehydrator. A gaseous stream having water vapor therein flows into the tube side of the capillaries. Water vapor permeates through the fibers to the shell side. A portion of the dehydrated stream is used as a purge stream for the shell side of the dehydrator. A pressure valve meter combination is used in the bypass stream to ensure that the pressure of the purge stream is maintained at a constant level independent of any variation in the pressure of the feed stream. This ensures that if there is an increase in pressure in the feed stream there is no increase in the purge rate and no corresponding increase in purge losses.

Abstract: Reverse osmosis, particularly for manually operating water desalination, is achieved using semipermeable membranes which selectively permeate purified water from a feed solution pressurized by reciprocating piston or diaphragm pump. The manual pump action is assisted by using two pump pistons to provide a continuous flow of feed solution to the concentrate side of the membrane to continuously flush the membrane surface. The concentration polarization is controlled by exhausting the high pressure concentrate to atmosphere through an orifice and relief valve.

Abstract: A broadcast antenna that generates circularly polarized waves and comprises a pair of conducting arms having portions forming a normal mode helix with one arm interrupted by an insulator to permit the connection of an internal feed line.

Abstract: A process of and apparatus for determining when the effective bromine contained in a polybromide impregnated resin cartridge used in a water disinfection system is depleted. The bromine content of the supply water is measured. When the bromine content falls below a pre-determined level, a comparative circuit is actuated to initiate flow of the supply water through a bromine cartridge assembly. At the same time, a timing cycle is initiated. The bromine content is continuously monitored and if it does not rise above the pre-determined level during the life of the timing cycle then an signal is output to indicate that the bromine cartridge is depleted.
