Patent EP-0264281-A2 (EP)
Inventor: MYERS ROBIN D
IPC: H04N1/46
Filed: 1987-10-15
Abstract: A technique is disclosed for matching a color, applicable for example to printing a color on paper which matches a color on a CRT display. Quantities of toners which will generate the matching color are determined and then a pattern of toners which will approximate those quantities is applied. To determine the quantities, a definition of the original color, such as its RGB coordinates, is converted to coordinates in a linear mixing space, such as CIE coordinates. These coordinates, together with coordinates of the toners, are then used to calculate quantities of toners which will produce a matching color. The calculations match hue, saturation and reflectance so that the matching color appears like the original color, so that characteristics of an original image are preserved. A table containing the area coverages of available toner patterns is used in selecting the toner pattern. A separate pattern for each toner may be selected by comparing the quantity of that toner with the area coverages of its available patterns to find the separate toner pattern which will come closest to that quantity. The selected separate patterns of the toners are then combined to obtain a combined toner pattern, which is then applied.

Abstract: A process for rapidly and uniformly heat treating a conduit section of a heat exchanger tube which has a heat sink such as a support plate is disclosed herein. The process utilizes a radiant heater assembly capable of directing heat from a zone whose length is less than the length of the conduit section to be stress relieved, and generally comprises the step of actuating the heater assembly, and sliding it step by step between the ends of the tube section for known time intervals in order to heat the tube section having nonhomogeneous thermal conductivity to a temperature that is substantially uniform along its length despite conductive heat losses through the support plate. The process allows heat exchanger tubes to be readily and reliably stress-relieved in the vicinity of the support plates of a nuclear steam generator.

Abstract: A computer aided drafting (CAD) procedure presents, for a three dimensional (3D) object to be modeled in a general purpose computer, dimensional and tolerance parameters appropriate to changes of view or parameters. The procedure requires but one model, the three dimensional solid model, for producing both dimensioned displays of the model and dimensioned drawings of views of the model. Dogleg extension lines are used to express 3D dimensions without ambiguity. These dogleg extension lines facilitate the presentation of information on paper or on a display screen and permit convenient alteration of presentations of 3D illustrations, with automatic correction of dimension and tolerance presentation. The operator of the CAD system enters dimension and tolerance information on a plan or elevation view, and this information is automatically converted to an appropriately corrected and presented axonometric presentation.

This video signal processing circuit supplies to a television set a composite video signal which enables a plurality of pictures to be displayed simultaneously on the screen of the television set. Since the plurality of video signals are synthesized by insertion of color difference signals, no switching noise is produced when the video signal of the SECAM system using FM is outputted. Accordingly, a synthesized composite video signal of a high quality can be obtained.

Abstract: In a satellite communication system for carrying out communication between a central station and local stations, each local station includes a receiving apparatus (41) which comprises a converting unit (43) for converting a received radio signal of a received carrier frequency into a converted signal by using a reception carrier signal of a reception carrier frequency and a demodulating unit (44) for demodulating the converted signal into a demodulated signal. Connected to the demodulating unit, a deciding unit (45) decides whether the demodulated signal is normal or abnormal. The deciding unit produces an abnormal signal when the demodulated signal is abnormal. After reception of the abnormal signal, a timer circuit (47) measures a lapsed time to produce a time up signal when the lapsed time is equal to an integral multiple of a predetermined time interval. Responsive to the time up signal, a supplying section (49) alternately supplies first and second carrier signals indicative of first and second memorized frequency signal preliminarily memorized in a memorizing section (48), respectively, one at a time as the reception carrier signal to the converting unit.

Abstract: The regeneration of soiled air filters for internal combustion engines is technically possible; cleaned air filter elements satisfy the product specification of car manufacturers. Repeated cleaning and reuse are also possible, as long as no mechanical damage occurs. The technical prerequisites for multiple use are thus satisfied, with the following social and economic consequences: conservation of resources, reduction of the load on waste disposal and the environment, and reduction in cost of filter use. Process steps and technical apparatuses for the regeneration of used filter elements are described. Important characteristics of the process are: The process steps precleaning, cleaning, drying and inspection are carried out in one set-up, the cleaning medium flows through the filter medium from the clean air side, and regenerated filter elements are marked as such. The installation for carrying out the regeneration process takes into account different filter types: Annular filter elements are put on to a cylindrical filter element carrier in large numbers, and the treatment steps cleaning, drying and inspection are carried out by changing over the material flows in one station. Rectangular (cylindrical) filter elements are used in small numbers per circulating support; the treatment steps cleaning, drying and inspection are carried out in different successive stations. <IMAGE>
