Abstract: An electrodeless inductively-coupled fluorescent lamp which operates at radio frequencies and contains an induction coil (1) which is inserted in a reentrant cavity (2) of the envelope (7) and is spread along the length of the reentrant cavity (2). The coil (1) is disposed within a cylinder (14) of thermally conductive metal. The use of the spread coil provides for reduction of starting and operation voltages of the lamp and results in lowering of the energy of ions bombarding the inner surface of the envelope (7) and the cavity (2) and therefore improves lamp maintenance and increases lamp life.

Abstract: A new planar phased array antenna is disclosed having M by N antenna cells with only M+N phase shifters. A grid of M+N feed lines with the M feed lines at a first frequency having a uniquely controllable phase and N feed lines at a second frequency with each feed line having a uniquely controllable phase are provided separating adjacent cells in the matrix. By coupling an antenna element through a mixer to one row and column feed, a phase for each antenna element in the array can be uniquely controlled through a scan, thereby providing a simplified planar array to be implemented as a patch antenna.

Abstract: An electrodeless inductively-coupled fluorescent lamp which operates at ro frequency comprising a bulbous envelope (1) filled with rare gas and metal vapor. A reentrant cavity (4) and an induction coil (6) are disposed in the cavity (4). The inner walls of the envelope (1) and the cavity (4) have a protective coating (3) and a phosphor coating (2). A metal Faraday cylinder (12) welded to the lamp base (13) is disposed between the cavity (4) and the coil (6) to reduce capacitive RF voltage between the coil and the plasma to improve lamp maintenance and remove heat. A tubulation (16) is disposed on the lamp axis to evacuate the envelope (1). The proximal end of the tubulation (16) has an expansion (20) with the volume (23) where the initial capacitive discharge is ignited.

Abstract: A method of manufacturing a concentrate from juice that may be used to make a powder that can be reconstituted as a juice drink by addition of water to the powder or to make a taffy-like solid that may be consumed without being reconstituted and in which the juice is freeze or spray dried, includes the use of lubricants and/or dextran to improve the texture of the dried juice so that it may be packaged and stored for later consumption.

Abstract: In this roll control system, suspension means are provided for resiliently suspending the vehicle wheels with variable hardness/softness characteristics, each suspension means including an actuator with a pressure chamber which increases or decreases wheel suspension height according to the supply or discharge of working fluid. Working fluid supply/discharge means are provided for the actuators, to supply and discharge working fluid to and from actuator pressure chambers. The road speed, the steering angle, and the actual body roll angle are detected. Means for computing and control computes a steady state vehicle body roll angle .phi..sub..infin. from the vehicle speed and steering angle, advances the phase of a signal indicative of .phi..sub..infin. to compute a compensating roll angle value .PHI..sub..infin., and then computes a difference value .phi. based upon a desired roll angle .phi..sub.a, .PHI..sub..infin., and the actual roll angle .phi..sub.t, according to the equation:.phi.=.phi..sub.a -(k1.PHI..

Abstract: In this system for vehicle roll control, a plurality of actuator assemblies are provided, one corresponding to each one of the vehicle wheels and resiliently suspending it from the vehicle body. These actuator assemblies have pressure chambers, and each is adapted to increase or decrease the vehicle height at a location corresponding to its corresponding vehicle wheel as respective results of supplying or discharging of working fluid to or from its pressure chamber. A plurality of working fluid supplying and discharging valves are provided corresponding to the actuator assemblies and serve to supply working fluid to the working fluid chambers and to discharge working fluid from the working fluid chambers. A vehicle speed detector senses the road speed of the vehicle, and a steering angle detector senses the steering angle of the vehicle. A control computer computes a steady state roll angle .phi..sub..infin.
