Title: Apparatus for reducing echo effects in picture transmission systems
IPC: H04N11/00
Filed: 1943-01-12
Abstract: 562,794. Television. PHILCO RADIO & TELEVISION CORPORATION. Jan. 12, 1943, No. 558. Convention date, March 19, 1942. [Classes 40 (iii) and 40 (v)] In a radio television system of the kind employing different carrier frequencies for the vision and the synchronizing signals, distortion of the received picture due to delayed reception of the synchronizing signals over a path involving reflection is substantially eliminated by proper choice of the difference between the two carrier frequencies. The echo signals give rise to alternate dark and light patches in each line of the picture as indicated in Fig. 3, and these may be caused to cancel each other out by choosing the carrier difference an odd multiple of half the line or frame frequency. In Fig. 4, the carrier generator 19 for the vision signal, and the carrier generator 20 for the synchronizing signals are alternately switched to the amplifier 22 by valves V1, V2 oppositely triggered by the synchronizing signals from the source 26. The carriers may be multiplied in frequency at 22 and are then 'amplitudemodulated by both vision and synchronizing signals supplied from 26, the modulated carriers passing to the aerial A through an amplifier 24 and side-band filter 25. The line synchronizing signal is fed from its source 26 to a frequency halver or divider 33, and thence to a multiplier 34 raising the frequency to an odd multiple, which is fed to the generator 20 to create therein a carrier frequency differing from the vision carrier frequency by an odd multiple of half the line frequency. Specification 562,707 is referred to.

Title: Improvements in or relating to methods of and apparatus for coating articles
IPC: B05D3/14
Filed: 1941-01-15
Abstract: 570,552. Coating processes. BRUSH DEVELOPMENT CO. Jan. 15, 1941, No. 573. Convention date, Jan. 15, 1940. [Class 95] A method of making a coated article, e.g. a coated piezoelectric unit, comprises subjecting the whole or a portion of the article, to which an excess of liquid coating material has been applied, to the action of an electrostatic force while the excess coating material is in a liquid state, and thereby removing the excess coating material from said article. In an apparatus for carrying out the method, the articles 11, to be coated, are held in spring clips 9 on a conveyer 1, and are carried through the liquid coating material 15 kept at constant level in the tank 13, and then between electrodes 19. A high potential difference is maintained between the electrodes 19 and the articles 11, and the excess coating material, which has accumulated under the action of gravity at the lower portions of the articles, is drawn off to the electrodes, usually in a fine stream or spray, while a thicker layer of coating is formed at the edges and corners of the article. By the time the articles have passed between the electrodes, the remaining coating material has set; and the articles may pass to a drying chamber, and to successive diping tanks and removing electrodes where additional coats are applied Other forms and arrangements of electrodes may be used. When the articles being coated are piezoelectric units a suitable coating liquid is a solution of shellac, and after application of two or three coats of shellac, one or more coats of a waterproofing vinyl resin composition may be applied.

Abstract: 1,088,421. Tubes coated with reagents; blood sedimentation rate tests. HARSHAW CHEMICALS Ltd. Dec. 29, 1964 [Jan. 7, 1964], No. 716/64. Heading B1X. [Also in Division B6] Capillary or small-bore glass tubes are provided with an internal uniform coating of powdered material by inserting a quantity of the powder 30 and a plurality of the tubes in each of two glass cylinders 24, 25 which are then coupled together by a threaded member 26 to which is secured a metal screen 27 through which the powder, but not the tubes, can pass, mounting the assembly at an angle to the horizontal, by means of rubber bands 20, on a wooden stand 14, and vibrating the assembly by means of a band of animal fur 13 having an enlargement 28 and mounted on a driven pulley 12 mounted obliquely so that the impact of the enlargement 28 on the assembly vibrates it and also causes it to rotate about its axis. Contact of the powder with the tubes, and also of the fur with the cylinders, produces an electrostatic charge which causes the powder to adhere to the inside of the tubes. (In order to obtain a uniform coating, the vibrating and rotating process is repeated several times with the cylinder assembly reversed in (the stand 14. The powder may be a mixture of disodium and dipotassium sequestrine. The coated tube is suitable for use in a sedimentation rate test for blood by placing the lower end in a drop of the blood at a small angle to the horizontal, so as to fill the tube. The Upper end of the tube is closed by the finger and the lower end embedded in plasticine, the tube being placed against a scale which measures the sedimentation after a given time. The tube may have an easily breakable intermediate zone, whereby it may be broken to extract blood for use in other tests, such as adding a drop to a copper sulphate solution for haemoglobin examination, or to obtain a tube of specific length filled with blood for a centrifugal packed cell volume test. The breakable zone may be a thin band of glass with a different co-efficient of expansion, formed by depositing a ring of a lithium salt, which ring is then fired.
