Title: Calendar timepiece
IPC: G04B19/253
Filed: 1954-07-15
Abstract: 781,767. Date indicators. ELBERG, B. July 11, 1955 [July 15, 1954], No. 20722/54. Addition to 718,896. Class 106 (4). A calendar clock comprises a central hand for indicating the day of the week and rotating tens and units dials for displaying the date through two adjacent windows in the clock dial above its centre. The calendar mechanism of the parent Specification is adapted for use in clocks with weaker springs, e.g. 8-day clocks, by doubling the number of teeth of the gear-wheels 35, 64 and 70, Figs. 6, 7, thus not only halving their speed but halving the power required to overcome the restraint of the springs 37, 65 and 41 since they bear on teeth half the distance apart. In a further modi, fication the cams 33, 42 are made double cams, thus further reducing the power required to drive the calendar mechanism. To protect the gears and cams from breaking by manual adjustments of the date and day at inappropriate times the manual pinions 49, 75 are mounted on the manual adjustment shafts 22, 62 by means of friction spring clutches. The calendar indications may be distinguished from the clock indications by the use of contrasting colours.

Title: A process and apparatus for the preparation of open-pored foamed plastics materials
IPC: B29C44/56
Filed: 1963-05-24
Abstract: Open-pored formed plastics material, specifically polyurethane, is obtained by subjecting sheets or strips of closed-pored material on either or both sides to brushing or shearing forces brought about by motion of the plastics material relative to static brushing means or by motion of brushing means relative to the plastics material. The brushing means may comprise true brushes, rubber rollers with rubber projections or wooden rollers covered with, e.g. napped coarse muslin, rough towel cloth or foam rubber.  Sheets up to 10 mm. thickness or greater may be treated.  With stationary brushes, it is advantageous to arrange for the brushes to be in increasingly harder contact with the strip in the direction of forward motion, e.g. by using progressively harder or shorter bristles.  The angle between the bristles and the sheet in the direction of forward motion may decrease from 110 to 70 degrees, preferably from 100 to 80 degrees. Figs. I and V show two forms of apparatus with stationary brushes. <PICT:0983733/C3/1>

Filed: 1922-08-02
Abstract: 204,460. A.M.A.C., Ltd., and Stokes, F. Aug. 2, 1922. Spray carburettors.-Several coaxial Venturi or equivalent tubes are employed, each tube being provided on its inlet side with a separate and coaxial control member adapted to regulate the air flow through it. The body A converges internally as at A2 and encloses fixed tubes B, C spaced apart by longitudinal ribs thereon. The fuel nozzle D secured by a band clip E and to which fuel may be supplied through a control nipple D3, passes transversely through the body and tubes and discharges into the inner Venturi C. The tubes B, C have control plugs G, F and the passage A2 has a plug H. These plugs are mounted telescopically on tubular members G2, H2, A5, are spaced some distance apart when closing the tubes and are loaded by springs J2, J3, J4. The tubular members G2, H2 are ported at G4, H3 to register with radial ports F2, G3 in the plugs as they are moved axially to open the tubes, thus admitting air from the interiors of the plugs to the choke tubes which they control. The plugs are actuated in the construction shown in Fig. 1 by a cable J attached to the smallest plug F. Each plug as it is withdrawn from its tube slides over the tubular part of and ultimately strikes against and opens the next largest plug until all are open. Air enters through ports A7 in a cap A6. The smallest plug may control the outlet from the fuel nozzle. The fuel may be discharged into the space between two tubes. Each plug may have an independent actuating cable, each loading spring then bearing either against the cap A6 or a port carried thereby, but generally it is only desirable to apply such a cable K to the plug H. Such a construction with all the plugs open. so as to produce one approximately stream-line plug, is shown in Fig. 5.
