IPC: H01Q1/36
Abstract: 930,382. Aerials. GENERAL ELECTRIC CO. April 13, 1960 [April 16, 1959], No. 13191/60. Class 40 (7). A wide - band aerial comprises inner and outer conductors, the outer being formed in a number of turns around the inner conductor. In one embodiment the aerial comprises an upper and a lower section, the sections being mirror images, Fig. 1. The inner conductors 22, 24 are wound as a helix of triangular cross-section, Fig. 2, and are of mesh. The outer conductors 26, 28 are wound as a helix of circular cross-section spaced radially from the inner conductor by insulators 52. The spacing between the inner and outer conductors varies cyclically and at the minima there is capacitive loading of the aerial. A coaxial feeder carrying a signal is connected to the inner and outer conductors at terminals 30, 31. A second signal to be diplexed with the first signal is fed in at both the top and bottom of the aerial. The aerial radiates omnidirectionally, and several aerials may be stacked to form an array. The crosssection of the outer helix may be elliptical or polygonal, for example square, Fig. 3 (not shown), and may be loaded by stubs. The inner conductor may be formed of sheet instead of mesh metal.

Title: Vibration compensation for IC engine - uses balance weights and compensation weights moving in different planes on single balancing shaft
Inventor: KREUTER ING PETER
IPC: F16F15/26
Filed: 1996-10-14
Abstract: A reciprocating-piston internal-combustion engine has a crankshaft 6 driving a balancing shaft 12 at twice crankshaft speed through gears 8, 10. At least one balancing weight 31 performs a substantially linear, oscillating movement, driven by slide member 27 and a throw of the balancing shaft. Compensation weights 20, 26 are similarly driven by slide members 18 and 24 on throws 14 and 16 of the balancing shaft, performing a similar movement to the balancing weights, but out of phase with them, and with each other. The time of minimum speed of the balancing weight coincides with the time of maximum speed of the compensation weight. In the example shown, the compensation weights move laterally on guides 22, while the balancing weight 31 moves vertically. Figures 2 to 4 show arrangements using connecting rods and pivoted mounting levers; figure 5 shows an arrangement for a three cylinder engine. The dual weight system minimizes energy transfer between shafts, thus minimizing noise and vibration.
