Abstract: The filter assembly includes a filter element (10) having an end surface and an end cap (20) connected to the end surface by spin welding. The end cap (20) has an outer diameter that need be no larger than the outer diameter of the end surface of the filter element. Prior to spin welding, the end cap (20) may have a surface with a sacrificial ridge extending from the surface. The end cap (20) is spin welded to the end surface of the filter element (10) by rotating the filter element (10) and the end cap (20) with respect to one another while contacting the sacrificial ridge with the end surface of the filter element, melting the sacrificial ridge by the contact with the filter element (10) to form a molten plastic, and joining the surface of the end cap (20) to the end surface of the filter element (10) with the molten plastic. Also disclosed is a method of spin welding a filter pack (11) to an end cap (20) without a sacrificial ridge.

IPC: F16F13/10

Abstract: A vibration isolating apparatus (10) in which a vibrating body (71), which is disposed within a pressure-receiving liquid chamber (34) and is connected to a mounting member such that a gap (84) is formed between an inner wall surface of the pressure-receiving liquid chamber (34) and the vibrating body (71), is disposed. An elongated limiting passage (80) is formed in the vibrating body so as to penetrate therethrough. The limiting passage communicates the pressure-receiving liquid chamber and an auxiliary liquid chamber (64) provided within the mounting member. When there is low-frequency vibration, there is liquid-column resonance of a liquid within the limiting passage. However, because the limiting passage is elongated, the liquid-column resonance of the liquid therein is large, and a high loss factor is obtained. Therefore, the low-frequency vibration is reliably absorbed. When there is high-frequency vibration, there is liquid-column resonance of the liquid in a vicinity of the gap. A dynamic spring constant decreases, and the high-frequency vibration is reliably absorbed.

Title: Terrestrial antennas for satellite communication system
Inventor: JHA ASU RAM
IPC: H01Q21/06
Filed: 1992-11-05
Abstract: Terrestrial antennas (10A, 10B, 10C and 10D) which are capable of transmitting and receiving radio signals directly to and from satellites in low Earth orbit are disclosed. The preferred embodiment of the invention employs circularly polarized, dual-frequency printed circuit antenna elements (136) measuring only a fraction of an inch in diameter. One embodiment (10A) includes an elevation array and an azimuth array which both reside on a trapezoidal, semi-conical housing that resembles a flattened pyramid. Both the top and the curved exterior of the pyramid support circular, slotted, printed circuit patches on their surfaces which bound individual radiating antenna elements (18). Since the entire antenna is only a few inches in diameter and is less than two inches high, it can be incorporated as an integral element of a telephone (T) or can be mounted at the end of a collapsible mast (CM). Other embodiments (10B, 10C, and 10D) of the invention employ hemispherical, cylindrical, and truncated hemispherical configurations. These unique antennas permit direct communication with satellites in low Earth orbit using the 20 and 30 GHz frequency bands. The antennas (10A, 10B, 10C and 10D) and their associated circuitry are sufficiently powerful to provide dependable service virtually anywhere on land, sea or in the air.
