Patent EP-0262818-A3 (EP)
Title: A method and apparatus for constructing circumferentially wrapped prestressed structures utilising a membrane
IPC: E04G11/04
Filed: 1987-09-09
Abstract: The present invention is directed to improve tank structures and the processes and apparatus for their construction. The walls of the prestressed tank are formed by inflating a membrane, applying one or more layers of rigidifying material outwardly of said membrane and then prestressing the walls by circumferentially wrapping prestressing material to minimize the tension in the rigidifying material when subject to loading. In another embodiment, wall forms are placed inwardly of said membrane to aid in the forming of the walls and circumferential prestressing. In the best mode of the invention, the walls are of reinforced plastic, fiberglass, or resin sandwich composite construction. Seismic countermeasures may also be used to protect the structure against earthquakes and other tremors, by the anchoring of the tank walls to the base and permitting the seismic forces to be shared by the seismic anchors. When a seismic disturbance occurs, the force acting on the structure can be transmitted and distributed to the footing and around the circumference of the tank.

Title: Supporting framework for suspended roofs
IPC: E04B7/14
Filed: 1987-01-14
Abstract: To prevent the vibrations caused by wind in suspended-roof supporting frameworks, the suspended-roof supporting framework has main chains composed of bar-shaped main links of relatively small cross section. The ends of these main links are connected to one another at joint centers, and the ends of the main chains are fastened to a stationary perimeter structure. The joint centers of adjacent main chains are connected by means of supplemental links of larger cross section. The supplemental links are larger in cross section than the main links, so they form supplemental chains which are heavier than the main chains. The supplemental chains extend obliquely relative to the main chains, and their ends are fastened to the perimeter structure.

Patent EP-0307250-A3 (EP)
Title: Method of separating flat metal alloy particles
IPC: B03B1/02
Filed: 1988-09-12
Abstract: A method is described for separating a mixture of 
flat metal alloy particles in which the particles of one 
alloy are generally smaller and less conductive than 
the particles of another alloy, e.g. a scrap mixture of 
aluminum-lithium alloy and other wrought aluminum alloys. 
In this method, the scrap mixture is thermally pretreated 
and then crushed into relatively flat particles, such that 
the aluminum-lithium alloy is fragmented into smaller 
particle sizes than the other wrought alloys. These 
particles are then physically separated based on 
differences in particle size, density and/or electric 
conductivity. For instance, the separation may be done by 
an eddy current separator or a dense media separator.

Title: Display improvement of a picture signal
IPC: H04N5/44
Filed: 1989-02-03
Abstract: To improve the reproduction of a video image, particularly for avoiding edge flicker, line flicker, line crawl or large-area flickering, different methods are known in which it is necessary to switch between individual methods as a function of movements. To avoid switching between different methods as a function of movement, a progressively recorded frame is divided into two fields, the second field being formed from the arithmetic mean between the current lines and the preceding lines and these two fields are reproduced at twice the frame repetition rate as the original frame. The invention is applied in image reproduction devices.

Title: Fiber optic amplifier
IPC: H01S3/05
Filed: 1984-09-20
Abstract: A side pumped, fiber optic amplifier comprises an optical fiber (12), having a first refractive index, formed of a laser material, such as Nd:YAG. A jacket (14), which surrounds the optical fiber (12), has a second refractive index, lower than the first refractive index. This jacket (14) is cone shaped and tapers from a large end (16) to a small end (18). High power laser diodes are mounted on the large end (16) to produce collimated pump light to pump the optical fiber material. The cone shaped jacket (14) focuses this pump light to an interaction region at the small end (18), where the jacket material is quite thin, e.g. on the same order of magnitude as the diameter of the optical fiber (12). The focused light is absorbed by the optical fiber (12) in this interaction region, and causes an electronic population inversion in the laser fiber material. A signal propagating through the optical fiber (12) stimulates spontaneous emission from the optically excited laser material, thereby resulting in amplification of the signal.

Title: Optical communication system for simultaneous transmission of a baseband digital signal and multiple microwave subcarriers
IPC: H04J4/00
Filed: 1989-09-12
Abstract: An optical communication system (Figs. 1-4, 
6-7) which includes an optical transmitter (Fig. 1) 
for transmitting an optical signal through a 
single-mode optical fiber (22, 88) to an optical 
receiver (Figs. 3, 9, 10). The optical transmitter 
includes an optical source for generating a light 
beam. The optical source is preferably a high speed 
laser diode (20, 86) emitting in a spectral range of 
1.3 - 1.6 micrometers. The light beam is intensity 
modulated with a composite modulation signal 
comprising one or more modulated microwave 
subcarriers and a baseband digital signal. The 
microwave subcarriers are typically in the frequency 
range between 2 and 20 gigahertz, and the baseband 
digital signal is typically a time-multiplexed 
signal carrying multiple voice and data channels. 
By simultaneously transmitting a baseband digital 
signal and multiple microwave subcarriers on a 
single optical fiber, the information-carrying 
capacity of the optical communication system is 
increased.

Abstract: The all plastic can includes an upwardly extending 
open mouth portion (20) with an inwardly tapering exterior 
surface (21) and a molded plastic end closure member (30) 
having an integrally formed rim portion (40) extending 
downwardly therefrom. An outwardly tapering interior 
surface (42) is provided on the rim (40) and is inclined 
to mate with the inwardly tapering exterior surface (21) 
of the open mouth portion (20) of the can body. Relative 
rotation is imparted between the end closure member (30)

connects the inwardly tapering exterior surface (21) of the 
open mouth portion (20) and the interior surface (42) of 
the rim portion (40) of the end closure member (30). An 
integrally formed outwardly extending rib (22) is provided 
on the inwardly tapering exterior surface (21) of the 
open mouth portion (20) to enhance the spin-bond 
between the end closure member (30) and the can body. A 
bead of hot melt material (50) is applied around the upper 
portion of the inwardly tapering exterior surface (21) of 
the open mouth portion (20) and serves to prevent entry 
into the interior of the product filled can body of any 
plastic dust particles generated by the spin-bonding of the 
end closure member (30) to the can body. The spin-bonding 
of the end closure member (30) provides a tamper evident 
closure for the can.
Patent EP-0351095-A3 (EP)
IPC: F16H59/68
Filed: 1989-06-28
Abstract: The time rate at which pressure increases in a 
friction element (96, 74, 98) engaged to produce a gear shift is 
controlled through operation of an accumulator (256, 260, 262). Shift 
valves (232, 236) in a hydraulic circuit produce selectively a 
connection between hydraulic lines associated with the 
friction elements to be engaged and a source of line 
pressure. A first control pressure has a magnitude that 
varies according to a required torque transmitting 
capacity of the friction element. A line modulator valve (220) 
produces a second control pressure having a magnitude 
that varies with the magnitude of the first control 
pressure but at a different rate. An accumulator 
includes a piston movable within a cylinder defining a 
first volume connected to the second control pressure 
output by the line modulator valve, and a first volume 
communicating with line pressure. The accumulator 
control valve directs this pressure to the second volume 
of the accumulator through an orifice having a 
predetermined diameter that controls the flow rate of 
fluid into the second volume of the accumulator. When 
line pressure is removed from the accumulator control 
valve to disengage the friction element, the clutch or 
brake is vented through the shift valve.
