Patent GB-1492740-A (GB)
Title: Preparation of half-tone images
IPC: H04N1/40
Filed: 1973-12-17
Abstract: 1492740 Facsimile receiver CROSFIELD ELECTRONICS Ltd 12 Dec 1974 [17 Dec 1973] 58324/73 Heading H4F [Also in Division G2] A half tone facsimile receiver includes means for continuous variation of the light intensity emanating from an exposure head to provide a continuous variation of image dot dimension. The exposure head, shown greatly magnified in Fig. 5A, comprises a PLZT modulator in the form of six light modulating windows 43 to 48 which may be "opened" by the application of signals to adjacent electrodes in order to pass a common laser. The windows are staggered in both the line and frame scan directions, delays D apply the respective signals to windows 44, 45, 47, 48 to bring corresponding exposed portions of film into sideby-side relationship across a scan line. The windows are arranged in the frame scan direction (i.e. horizontally displaced as seen in Fig. 5A) to expose overlapping portions of film, each window yielding a triangular intensity profile as seen at the bottom of Fig. 5A. The line scan stagger (i.e. vertical displacement as seen in Fig. 5A) avoids interference in the overlap regions. The sum of these profiles provides a uniform exposure over the picture element reducing to zero intensity at the ends thereof in a continuous manner. By varying the signal applied to the end windows Fig. 3A to be opened, the composite profile of the elemental light intensity Fig. 3B may be varied to trigger the film threshold in a continuous manner resulting in the continuous variation in image dot area shown in Fig. 3C. The signals applied to the windows are derived from a circuit Fig. 4 in which the incoming picture signal P is added at seven summing junctions 21 to 27 to components S of a screen pattern signal. The outputs from adjacent pairs of junctions are processed by units 28 and 29 to produce the window control signals. In a second embodiment Fig. 5B (not shown) a conventional incoherent light source and condenser lens direct light through a PLZT modulator and an aperture stop placed between a pair of polarizing elements. The output is focused by a lens on to the film. In a third embodiment Figs. 6A to 6C (not shown) point light sources modulated by respective signals, are focused, in overlapping side by side relation across a line, through a diamond shape apertured lens. In a fourth embodiment Figs. 7A to 7E (not shown) l.e.d.'s are used as sources and focused through a square shape apertured lens having a positive or negative auxiliary cylindrical lens to effect a defocusing of images across the line to obtain the desired degree of light intensity variation and overlap in the frame scan direction. In each embodiment the film is mounted on a rotating drum and the scanning head on a relatively slowly rotating lead screw to effect a helical scan Fig. 1 (not shown).

Patent GB-660004-A (GB)
Abstract: 660,004. Knitting - machines. BATA, NARODNI PODNIK. June 29,1948 [July 14, 1947], No. 17418/48. Class 74 (ii). The picot bar and clocking point bar of a straight-bar machine are brought into or taken out of operative position by ratchet-and-pawl mechanism associated with transmission gearing. The picot bar 1 is actuated by ratchetwheels 14, 15 secured to a gear 12 in mesh with a further gear 10 having a spiral groove 9 in one face. A rack bar 7 has a pin 8 fitting in the groove 9 and rotation of the gear 10 causes the bar 7 to rotate a shaft 4 to raise or lower the bar 1. The direction of rotation is controlled by a bluff 16. The bar 1 swings down slightly past its working position to enable a catch 25 to engage behind an arm 24 on its shaft 4. A spring-loaded stop 31 presses the bar 1 back to the working position against the catch 25. The catch is released by longitudinal motion of one of the fashioning point bars 30, the bar 30 carrying a pin 29 which forces the catch 25 downwards. The clocking points 36 are raised and lowered in a similar manner to the picot points and their ratchet-wheels may be coaxial with the wheels 14, 15, one bluff controlling all four. The device is applicable to multi-section machines. The gears 10 may carry disc cams instead of grooves 9.

Title: Resealable Composite Road and Methods for Sealing and Resealing Concrete Using Microwave Energy
IPC: E01C19/48
Filed: 1978-12-14
Abstract: Portland cement concrete 12 at a roadbed, bridge deck or the like is quickly and deeply heated and dried by directing microwave energy into the concrete and by applying hot gas to the surface. A layer of thermoplastic sealant 16 is applied to the hot concrete followed by an overlayer of asphaltic concrete 17 having a higher softening temperature than the sealant layer. Compaction then produces a composite pavement which is sealed against water intrusion and which can be quickly, easily and economically resealed and resurfaced at a later time using little or no additional paving materials. Resealing and resurfacing is accomplished by deeply reheating all three layers by microwave irradiation followed by recompaction. If cracking and deterioration are severe, the asphaltic concrete layer may be remixed and rescreeded between the reheating and recompaction steps. <IMAGE>

Abstract: PCT No. PCT/DE79/00090 Sec. 371 Date Apr. 21, 1980 Sec. 102(e) Date Apr. 21, 1980 PCT Filed Aug. 18, 1979 PCT Pub. No. WO80/00423 PCT Pub. Date Mar. 20, 1980. A pulp suspension of waste paper which is laden with air bubbles is introduced into a flotation cell. Fine air bubbles rise through the pulp suspension toward the top. Printing ink and other impurities are deposited on the bubbles which form a foam layer on the surface of the pulp suspension. The foam which is laden with impurities is drawn off from the surface. The fibers which have been subjected to preliminary purification in this manner sink downwardly. For reducing the number of cells connected in series to fewer than a third, while obtaining the same degree of whiteness, the fibers which were subjected to preliminary purification are drawn off and are once again supplied to the flotation cell in the form of an air-laden pulp suspension. Alternatively, instead of the air-laden pulp suspension, a water-air suspension can be injected. The air bubbles which are thus introduced once again rise toward the top and traverse the sinking fibers in a counterflow. As a result, an intensive air-pulp contact is created.
