Abstract: U-dipole radiating elements (10) and associated feed conductors (20, 22) are cut or stamped from brass sheet stock. Each U-dipole (10) is then bent up at 90 degrees to the signal distribution conductor (22) which is supported in front of a reflector (12). The U-dipole element (10) includes a first dipole-type conductor segment (14) connected near one end to a feed segment (20) which is the sole signal feed path to the U-dipole element. A second dipole-type conductor segment (16), which is spaced from and parallel to and coextensive with first segment (14), is connected to the other end of the first segment (14). An antenna may include one or more individual U-dipole elements cut from sheet stock and connected to feed points. In a linear array antenna configuration, a group of U-dipole elements (10a-10b) and associated signal feed network components may be cut in a unitary form from a sheet of conductive material and supported in front of a reflector surface.

Abstract: An oscillating belt sander or spindle sander is disclosed. The sander includes a motor shaft that extends upwardly through a worktable that supports a workpiece. The motor shaft supports a belt sander or spindle sander sanding surface. A combined motor and mechanical drive transmits rotational and reciprocating motion to the motor shaft which includes input and output motor shaft ends. The motor operates to impart rotational motion through the output motor shaft end while the mechanical drive is connected to the input motor shaft end and also imparts reciprocating motion through the output motor shaft end. The output motor shaft end facilitates interchangeable mounting of a spindle sander sleeve or a sanding belt. Thus, the sander is readily adaptable for conversion to a belt sander or spindle sander, as may be desired.

Abstract: In a process for making detergent tablets comprising spraying a coating of a water-soluble organic polymeric binder onto the exterior of particles of detergent composition containing detergent active and detergency builder and compacting the composition, the improvement comprises spraying an external coating of a film-forming water-soluble organic polymer onto the tablets. The coating on the tablet exterior reduces friability and abrasion and provides extra enhancement of strength while permitting disintegration/dissolution in a wash liquor.

Abstract: A method and system are provided for finishing a concrete floor that exce approximately 50 feet in width. A riding trowel of the type that forms a windrow of loosened concrete material in its wake is positioned on the concrete floor. The riding trowel has a straight edge coupled thereto by a support assembly that positions the straight edge to cross the windrow at a substantially perpendicular angle thereto within line-of-sight of an operator. A power assembly is coupled between the straight edge and the riding trowel for independently controlling vertical and pivoting movement of the straight edge. The riding trowel is driven on the concrete floor and the straight edge is moved along the concrete floor simultaneously with the riding trowel.

Abstract: In a cellular type communication system a sector antenna 12 provides coverage of a sector with a relatively low receive gain. A multi-beam antenna 20 covers the same sector with a plurality of narrower beams 21', 22', 23' and 24' providing higher gain. A multi-beam antenna system 10 provides higher gain operation by selecting the one of the narrower beams 21', 22', 23' or 24' currently providing best reception of a signal transmitted by a user and coupling that selected beam to a system receiver 18. Beam selection is accomplished by sequentially coupling each narrow beam to a microprocessor based control unit 40 and storing samples of user signals as received in each narrow beam on a continuing repetitive basis. The stored samples are then analyzed in order to select the beam currently providing best reception.

Abstract: A refrigerant air analyzer and purge system for detecting and purging air within a refrigerant system or supply. The analyzer includes a vented test chamber, means for controlling a flow rate of refrigerant and an oxygen sensor. The means for controlling receives refrigerant from the refrigerant supply and provides the refrigerant to the test chamber through an inlet of the test chamber. The means for controlling limits the pressure and flow rate of refrigerant provided to the test chamber. The oxygen sensor is coupled to the test chamber and produces a signal which is a function of the oxygen level within the test chamber. The means for controlling is connected to the oxygen sensor for receiving the oxygen signal and providing a display.

Abstract: Aircraft-mounted Identification Friend or Foe (IFF) antennas employ a linear array of radiator elements positioned transverse to the boresight axis. With an azimuth determination capability, but lacking elevation resolution, such antennas are subject to coning errors in determining the azimuth bearing of a target at an altitude differential. With use of a linear array (10) of multi-radiator elements (11, 12, 13), an output signal (23) having the characteristic of an amplitude which increases for off-boresight targets is provided. That signal is compared to a typical form of antenna system output signal (22), which has an amplitude which decreases for off-boresight targets. By such amplitude comparison, the angle (.beta.) to a target is determined and used to provide an azimuth correction factor (53). An apparent azimuth bearing (54) subject to coning error can then be corrected (55) to provide the true azimuth angle to a target (56).

Abstract: An assembly, preferably comprising a clearance pole, includes a first pole element with a first horizontal portion and a second vertical portion, and a second tubular pole element mounted to the ground, extending vertically, and receiving the first pole second portion. The first and second pole elements are mounted so that the first element is rotatable with respect to the second about a vertical axis. The slanted surface of an ultra-high molecular weight polyethylene block acts as a cam follower engaging a rod, bar, or tube which acts as a cam, the structures biasing the first pole element first portion to a home position. A dry lubricant is provided between the pole element bearing surfaces to provide relatively friction-free rotation between them.
