Title: Loop applicator for high frequency electrodeless lamps
Inventor: LAPATOVICH WALTER P
IPC: F21S2/00
Filed: 1992-08-25
Abstract: A high frequency applicator for energizing electrodeless lamps is described. The applicators are made of two loops of wire electrically attached to the ends of phased feed points of a planar transmission line. The loops are face each other and are positioned so as to form a gap in which a lamp capsule is placed. Each loop is made of three partial turns, the first and second turns being parallel to each other, each partial turn having a first and second end and the third partial turn is attached to the second end of each partial turn and positioned orthogonal the first and second turns. The plane formed by the third turn makes a dihedral angle between 0 and 135° with the planar transmission line.

Abstract: An rf, phase-array, microstrip antenna having a slotted ground plane mounted on one surface of a dielectric substrate.  A network of strip lines  is  mounted on an opposed surface of the dielectric substrate.  The network includes eight parallel rows of coupling strip lines mounted in superposition with eight rows of radiating slots.   The slots in each row form a linear array. The slot spacing in each row is uniform and is different for different rows.  The network further includes an input/output strip line, a plurality of switchable microstrip circulators and a plurality of branching strip lines connected to the circulators in a tree network.  A scanning circuit is connected to the control terminals of the circulators for selectively completing an rf transmission path between the input/output strip line and the coupling strip lines.  Each linear array is directional, having a major lobe, and each major lobe is oriented in a different direction.  Periodic switching by the scanning circuit between the linear arrays causes the antenna to scan a region of space via the different  major lobes.

Abstract: A hydraulically operated edge-of-dock dock leveler including a deck plate having its rear edge hinged to the dock and an extension lip is hinged to the front edge of the deck plate. In the storage position the deck plate is located in a generally horizontal position and the lip hangs downwardly in a generally vertical pendant position. A hydraulic cylinder unit interconnects the frame of the dock leveler with the deck plate and extension of the cylinder unit acts to move the deck plate to a generally vertical position where a latch that is pivotally connected to the underside of the lip engages an abutment on the frame to lock the deck plate in the vertical position. Retraction of the cylinder unit will pull the deck plate down and the linkage between the deck plate, the lip and the frame enables the outer edge of the lip to move in a generally curved path into engagement with the bed of a carrier. The hydraulic system for operating the cylinder unit includes a valve mechanism and when the cylinder unit is fully extended, as the deck plate is pivoted upwardly, the pressure increase in the hydraulic system shifts the valve and automatically retracts the cylinder unit,

Abstract: process for removing volatile constituents from a polymer dispersion or solution by stripping with a carrier gas is disclosed.  The carrier gas being, in the case of a polymer solution, the vapor of the solvent used for the polymer solution as an inert gas saturated with said vapor.  In the case of a polymer dispersion, the vapor of the dispersing medium used for the polymer dispersion or an inert gas saturated with said vapor.          In both processes certain amount of the carrier gas is passed through the polymer dispersion or solution, the volatile constituents taken up the carrier gas on passage through the polymer dispersion or solution are then removed from the carrier gas in such a manner that the energy content of the carrier gas remains essentially unchanged.  The carrier gas thus obtained is then reused for further removal of volatile constituents from the same polymer dispersion or solution by stripping.

Title: Dehumidification apparatus
Inventor: BERNER ERLING
IPC: B01D53/26
Filed: 1993-03-24
Abstract: ABSTRACT    An apparatus and method for dehumidifying air includes at least one bidirectional duct with at least one port at each end which are regulated by valves.  A desiccant containing matrix is disposed within each bidirectional duct.  One or more fans are adapted to produce substantially axial air flow in two directions through each bidirectional duct: a first direction during a regeneration phase of the dehumidifying cycle and a second direction during a process phase of the dehumidifying cycle. In the process direction, air from the enclosure enters one end of the duct, passes through the desiccant containing matrix where moisture is adsorbed by the matrix and exits through the opposite end of the duct back to the enclosure.          The air is thus at a lower relative humidity when it leaves the apparatus.  Upon reversal of the air flow direction, the air is drawn into the duct from a source outside the enclosure, heated by a heater, either before or after entering the duct passed through the desiccant containing matrix where moisture is removed from the matrix and exits into the source of air. The air thus has a higher moisture content when it is exhausted from the apparatus.

Title: Electro-vac decontamination process
Inventor: MALOT JAMES J
IPC: E21B43/24
Filed: 1992-04-21
Abstract: A combination of a vacuum extraction source (3) (to withdraw volatilized contaminants and fluids) and electric current (to heat in situ volatile contaminants and geologic strata) to remove contaminants from the vadose zone. Raising the soil temperature and thereby imparting heat energy to the contaminants makes the vacuum extraction source (3) of the contaminants more effective. Also, heating certain geologic strata, such as a clay, that resist vacuum air flow, tends to speed volatilization within such strata, speed the drying of such strata, and improve the effectiveness of the vacuum extraction source (3) therein. Various placement strategies for electrodes (7) are used in this invention to accommodate specific site conditions.
