    Abstract: 345,761. Filters. LAMORT FILS, E. ET M., Vitry-le-Francois, Marne, France. Feb. 12, 1930, No. 4766. Convention date, Feb. 22, 1929. [Class 46.] Apparatus for filtering the feedwaters of industrial apparatus comprises a filtering surface within a chamber, an inlet to and an outlet from the space between the filtering surface and the walls of the chamber, an outlet for filtered liquid from the interior of the filtering surface, and movable partitions making joint with the filtering surface and with the chamber walls to divide the space into parts, so that the inlet opens into one part and the outlet into the other and the filter may be cleansed by cutting off the supply to one of its parts and causing the clean liquid coming from the other part to be directed against the clean side of the first part, the clean liquid traversing the first part in a direction opposite to the normal flow and carrying off the impurities. The apparatus comprises a cylindrical cage 4 mounted in a coaxial cylindrical chamber 1 having three pipe connections furnished with cocks 10, 11, 12. The cage makes tight joints at its ends with the chamber 1 and is rotatable by means of a handle 5 projecting through the cover 2 of the chamber. One end of the cage is solid and the other apertured, while the cylindrical wall is perforated all over. Two diametrically opposite bars 6, 7 are secured by screws 8 and make tight joints when in contact with the walls of the chamber 1. Removable sleeves of wire gauze or fabric are gripped between the bars 6, 7 and the cage 4. In the normal filtering position the bars are directly opposite the centre of the pipes, the cock 10 is closed, and the cocks 11, 12 open. One part of the filter may be cleansed by turning the cage into the position shown in Fig. 4, closing the cock 12, and opening the cock 10, so that the water passes under pressure inward through one part of the filter and outward through the other. To cleanse the other part the cage is moved so as to bring the bars 6, 7 to the other side of the inlet and outlet pipes. The space between the sleeve and the chamber wall may be flushed out by opening the cock 10 and closing the cock 12 with the cage in normal filtering position. Alternating movements of the cage may be effected mechanically. Several filters may be connected to one feed pipe, which may be under pressure or vacuum.

    Abstract: 362,933. Filters ; toothed gearing. BARTLETT HAYWARD CO., Scott Street, Baltimore, U.S.A.-(Assignees of Center, A. L. ; c/o Bartlett Hayward Co., Scott Street, Baltimore, U.S.A.) Sept. 5, 1930, No. 26575. Convention date, Oct. 2, 1929. [Class 46.] In apparatus comprising a rotary filter element partially immersed in the liquid to be filtered, means are provided for giving to the element an oscillatory movement relatively to the liquid container, such oscillatory movement being approximately perpendicular to the vertical paths of settlement of the solid particles in the liquid. Tubular filtering elements 19 are mounted in end members 14, which are rotated so that each element is submerged in the material under treatment in a trough 12 and then raised for the discharge of separated solid matter from the element. The rotational movement is oscillatory, each forward step being succeeded by a shorter backward step, and the elements themselves keep the material under treatment in agitation. Each tubular element comprises filtering material 25, Fig. 7, wound or stretched over a tube 20 which has external ribs or corrugations 21 and is slotted so that the spaces between the ribs communicate with the inner space 24. The tubes are attached to the end members 14 by means of screws 27, and one end member is formed with passages 30, Fig. 2, which connect the elements to a distributing valve 36, by means of which each element is successively subjected to suction and supplied with fluid under pressure to discharge the solid matter from the element. To facilitate communication between the elements and the passages 30, the elements are made to taper slightly towards the opposite end. Solid matter falls from the elements into a hopper 50, Fig. 3, and is passed by a conveyer 54 to a discharge shoot at one end. The material is supplied to the trough through a pipe 86. Longitudinal bars 88 and vertical bars 89 prevent rhythmic movement of the material. The removal of the cakes from the elements is aided by a flexible wiper 92 attached to a rigid support 90 which can be adjusted on brackets 91, so that the wiper is not in actual contact with the filtering material. An auxiliary wiper 97 hinged to the support 90 may also be provided. The end members 14, which are carried by annular runners 15 engaging rollers 16 on frames 17 supported on flanges on the edges of the trough 12, are rotated by toothed wheels 57 meshing with gear wheels on a longitudinal shaft 59, Fig. 3. Suitable gearing for giving the shaft 59 the desired motion is shown in Fig. 12. A driving shaft 63 carries an eccentric 66 with a pinion 69 fixed thereto. The pinion gears with a wheel 71 on a shaft 72 which also carries a wheel 73 gearing with a wheel 74 on the shaft 59. The shaft 72 is mounted in a casting 75 which is free to oscillate on the shaft 59. An arm 78 connected to the shaft 72 and to a disc 81 connected to the stub shaft of the pinion 69 keeps the pinion in gear with the wheel 71. As the eccentric 66 rotates with the shaft 63, the shaft 72 is rotated by the pinion 69 and is at the same time oscillated about the shaft 59, and the shaft 59 is rotated discontinously each forward step being succeeded by a shorter backward step.

    Abstract: An information transfer system includes a transmitter for transferring to a receiver an information signal having main data and sub data. The sub data includes coded text lines having a plurality of character codes. The receiver is provided with a character display unit for displaying characters corresponding with the character codes in the coded text lines. The number of character display positions is less than the number of character codes in the coded text line. The receiver is further provided with display control means for controlling the display of characters corresponding to the character codes included in the coded text line in dependence on serial control codes included in the coded text line. Parts of the text in the sub data may be shown on both a full multi-line display units for displaying full text lines and a 1-line display with a relative small number of digits.

    Abstract: The application relates to an information transfer system, comprising a receiver (3) and a transmitter (1) for transferring an information signal to the receiver (3) via a transfer medium (2). The information signal comprises main data and sub data. The sub data comprises coded text lines having a plurality of character codes. The receiver is provided with a character display unit (10) for displaying characters corresponding with the character codes in the coded text lines. The number of character display positions is less than the number of character codes in the coded text line. The receiver is provided with display control means (9) for controlling the display of characters corresponding to the character codes included in the coded text line in dependence on serial control codes included in the coded text line. The system enables that significant parts of the text information available in the sub data can be shown on both a full multi-line display units for displaying full text lines and a 1-line display with a relative small number of digits. The invention is very suitable for systems with small sized receivers, such as e.g. portable players and car radios, and receivers with a display on its remote controller, because there is not much space available for a display unit.
