Patent EP-0221695-A2 (EP)
Inventor: EPWORTH RICHARD EDWARD
IPC: G02B6/28
Filed: 1986-10-10
Abstract: An optical fibre network which does not require the fibre (1) to be broken to introduce new terminals (nodes) (3). Information is introduced into the fibre by modulating, particularly by modulating mode coupling, optical power transmitted into the fibre from a source (2) at one or both of its ends. The nodes include tapping means for extracting information. If resonant mode coupling is employed a common grating (11,16) may be used for introducing and extracting information. Such a non-intrusive network may be overlaid on a conventional local area optical network (30 Fig.7) between two nodes (B,C) thereof, the fibre being common to both networks. The nodes (A-G) of the conventional network communicate in one direction along the fibre, whereas the nodes (31 to 36) of the non-intrusive network communicate in the opposite direction along the fibre.

Abstract: An optical communications system for providing wavelength division multiplexed communications with high spectral channel density and increased sensitivity and selectivity through coherent detection utilizes a fixed frequency source (14) for introducing at least one fixed frequency carrier for system-wide propagation through a system bus (12). Terminal devices (TD₀ . . . TD n ) coupled to the system bus (12) functioning as transmitters remove a portion of the system-wide carrier energy and effect a frequency translation and modulation of the translated carrier energy for return to the system bus as a modulated, frequency shifted information bearing signal. Terminal devices functioning as a receiver effect either synchronous homodyne or heterodyne coherent detection by removing a portion of the system-wide carrier energy, option­ally effecting a frequency translation, and combining the frequency shifted carrier energy with that of the frequency shifted information bearing signal to effect coherent detec­tion. Where the relative frequency translation of information bearing signal and the locally shifted demodulating carrier energy are the same, homodyne detection is achieved, and, where the relative frequency shift of the information bearing signal and the locally shifted carrier energy is different, an intermediate frequency is provided for subsequent process­ing.

Abstract: A papermaking machine is modified by replacing a conventional rotatable couch roll by a stationary couch device (14) that still serves the essential functions of the roll, namely dewatering of the furnish (12) carried by the web (10) and modification of the direction of travel of the web to turn it down towards the main drive roll (16). This stationary device is made of an abrasion resistant ceramic material and has a member (24) with a convexly curved upper surface (22) on which the web slides. Water is sucked from the furnish by a vacuum applied through perforations (34, 36) in the member. The majority of these perforations preferably take the form of slots that extend obliquely to both the transverse extent of the machine and the direction of web travel. The arrangement permits easier and more effective maintenance of the vacuum than with a couch roll and more efficient dewatering, with no rewetting of the web or furnish when leaving the couch device.

Abstract: A method for use in a modern slaughterhouse operation for testing carcasses to be processed for one or more characteristics indicative of a carcass containing harmful, questionable or undesirable matter is substantially automated using unique bar code labels (25) on test tube racks (17), test tubes (16) and microplates (40) along with a computer to record and display individual test results in an organized fashion. The computer reads optical density values from a spectrophotometer and calculates test results for the samples based upon these values. Positive test results are displayed prominently indicating that the corresponding carcass may contain questionable matter. The testing is done using an immunoassay which would be effective for the detection of trichinosis in swine, or a standard ELISA test effective for detecting a level of sulfamethazine in pigs indicative of the use of antibiotics. Test results are available well before the dismemberment and processing of a carcass, such that if a positive test result is encountered the corresponding carcass may be removed from the routine processing procedure.

Abstract: The invention resides in a Television Signal Transmission Security System which provides a higher degree of security then previously possible by utilizing encoding and decoding technology which effectively prevents pirating by amateurs or experimenters. The television signal transmitted is encoded by injecting one or more interfering carriers (24, 26) in specific frequency slots in close proximity to the video carrier (10). Interfering carriers (24, 26) can be injected either above or below the video carrier (10) between harmonics (41-44) of the horizontal frequencies. Combinations of interfering carriers (24, 26) provide coding techniques making the system virtually pirate proof. The interfering carrier (24, 26) is removed by very narrow band rejection filters (100-113) having a rejection band attenuation greater than about 40dB over bandwidth of up to 4000Hz and a 3db bandwidth of approximately 5kHz. The filters (100-113) are constructed using advanced technology to produce the quartz crystal bulk resonators or surface acoustic wave filters. Pre-compensation at the transmitter improves overall amplitude and phase response to provide a nearly perfect decoded picture.

Abstract: A tachograph for motor vehicles has a diagram-disc carrier mounted rotatably on a carrier plate, driven in rotation by a clock and intended for clamping at least one diagram disc. The diagram-disc carrier is arranged in a chamber of the housing when the tachograph is in the operative state and can be pivoted out of this chamber when the tachograph is inoperative. An output wheel of the clock meshes with an intermediate wheel, the axis of rotation of which extends transversely relative to the axis of rotation of the output wheel. The intermediate wheel is mounted in a first housing part which is pivotable about the axis of rotation of the output wheel. The intermediate wheel is connected fixedly in terms of rotation via a telescopic rod to a gearwheel which is mounted in a second housing part and which drives a driving wheel of the diagram-disc carrier. The second housing part is pivotable about the axis of the diagram-disc carrier, so that, in the operative and inoperative states, the diagram disc is always driven exactly according to time and, via the telescopic rod, the clamping and release of the diagram discs on the diagram-disc carrier can also be ensured. <IMAGE>
