Abstract: An apparatus for positioning a directional antenna (12) of a remote ground terminal (6) which transmits and receives signals to and from a satellite (4) via the antenna (12).      The apparatus includes a signal generator (52) for producing a frequency variable reference signal (35) having a variable duty cycle, and a controller (55) which operates to analyze the signals received from the satellite (4) and to vary the duty cycle of the reference signal (35) in accordance with an identification tag forming part of the received signals.  The apparatus further includes a detector which receives the reference signal (35) and produces an antenna pointing signal (77) having an average amplitude proportional to the duty cycle of the reference signal (35). The controller (55) commands the signal generator (52) to produce a reference signal (35) having a first duty cycle when a signal having an identification tag not corresponding to a designated central hub station (5) is received by the antenna (12), and a reference signal (35) having a second duty cycle when a signal having an identification tag corresponding to the designated central hub station (5) is received by the antenna (12). The reference signal (35) having the first duty cycle causes the average amplitude of the antenna pointing signal (77) to equal a first value, while a reference signal (35) having the second duty cycle causes the average amplitude of the antenna pointing signal (77) to equal a second value. During installation, the antenna (12) is rotated until the average amplitude of the antenna pointing signal (77) equals the second value.

Title: Optical information carrier
Inventor: TOMPKIN WAYNE ROBERT
IPC: G03H1/18

Granted: 2006-11-07
Abstract: An information carrier is in the form of a composite laminate (2) with a first, a second and a third layer (3; 4; 5) having respective refractive indices n3, n4, n5. The second layer (4) forms structures (7) by only partially covering the first layer (3). The third layer (5) covers over the second layer (4) or the first layer (3) respectively in direct contact. The surface of the first layer (3) has surface elements (14) with first and second diffraction structures (6a; 6b) which produce a visually verifiable authenticity feature or which serve for reading out the information contained in the structures (7). The refractive indices n4 and n5 are substantially real in the visible range and therefore the second and third layers (4; 5) are transparent. The differences ¦n4-n3¦ and ¦n5-n3¦ are greater than 0.2 over large parts of the visible range so that the first diffraction structures (6a) produce visible diffraction effects independently of the structures (7). The differences n4-n3 and n5-n3 are of approximately equal magnitude in the visible range so that the structures (7) are invisible. In a second predetermined spectral range L the absolute difference ¦n5-n4¦ is at least 0.1 so that in the reading operation using a suitable light beam the structures (7) produce a measurable change in the light beam which is diffracted at the second diffraction structures (6b).

Abstract: An electro-hydraulic operating system for an extensible boom includes one or more hydraulic cylinders for imparting relative motion between the boom sections to retract the boom according to an electronically stored program of sequences of movement and speeds. A source of pressurized hydraulic fluid is fed through appropriate control valves which include solenoid valves in fluid communication with a source of pressurized hydraulic fluid. The solenoid control valves are supplied with control currents proportional to the desired flow rates of fluid to the hydraulic cylinders in order to achieve speed and position control according to the stored program. A metering valve structure is provided for operation in conjunction with the solenoid control valves. The metering valve includes an associated pilot valve which receives variable pressure signals from the solenoid control valves to achieve the metering of fluid to the hydraulic cylinders in proportion to the characteristics of the control current supplied to the solenoid valves. The electrical control signals are such that the hydraulic cylinders may move associated boom sections at gradually increasing speeds during a starting period of any cycle of movement of the section, at a substantially constant speed during an intermediate period of movement and at a gradually decreasing speed during a stopping period preceding the end of the cycle of movement, thereby providing soft start and soft stop of the sections.

Abstract: A fluid damped bushing (10, 100) comprising a metallic sleeve (12, 112) and an annular elastomeric body (14, 114) mold bonded to the exterior of the metallic sleeve. The elastomeric body has a spaced apart pair of fluid containing recesses (18, 118 and 20, 120) in its exterior surface with a serpentine shaped inertia track (26, 126) in the outermost surface of the elastomeric body to provide communication between the recesses. A window metal sleeve (16, 116) is encapsulated within the elastomeric body by mold bonding, and the window metal sleeve has a longitudinally spaced apart pair of rings (30, 130 and 32, 132) above and below the level of the recesses, respectively, and a diametrically opposed pair of webs (38, 138 and 40, 140) extending between the rings. In a first embodiment, a plurality of outwardly projecting pads (28) is located in one of the webs in the region of the inertia track to prevent deformation of the inertia track under load. The annular elastomeric body is inserted into an outer metallic sleeve (36, 136), while the sleeve and the elastomeric body are immersed in a damping fluid, and the diameter of the outer sleeve is then reduced by a swaging process to tightly seal the sleeve against the annular elastomeric body and to seal the damping fluid in the recesses and the inertia track. In another embodiment of the invention the metallic sleeve (112) has a generally elliptical, axially short rigid polymeric collar (140) affixed to the central portion thereof. The radially longer lobes (140a) of the collar are aligned with the recesses (118, 120) and serve to limit the amount of radial deflection of the bushing (100).
