Abstract: RADIALLY EXPANSIBLE COLLET FOR A TUBULAR SLEEVE          ABSTRACT OF THE DISCLOSURE A radially expansible supporting collet for a tubular light-weight sleeve upon which a continuous filament, yarn, or roving may be wound.  The collet comprises a plurality of axially extending, sleeve contacting bars carried on a generally cylindrical body which is rotated on its normal axis.  At least one generally annular, closed, pneumatically expansible bladder is carried by and rotates with the body.  The bladder is located inwardly of the bars and may be connected to a source of air under pressure. When the bladder is expanded by the air, it presses outwardly against the bars to move them radially outwardly against the interior of the sleeve in order to hold the sleeve concentric with the axis of the body, to prevent its axial movement and to transmit torque to the sleeve.

Abstract: REMOTE ACTUATED METERING VALVE              Abstract of the Disclosure A remote actuated metering valve system for supplying water to a washing fixture includes a main metering valve and at least one remote actuating relief valve connected to the main valve by tubing.  The main metering valve has an inlet and an outlet with a valve seat between them and a movable piston which when the valve is in the normal closed position has its front face seated on the valve seat and its elongated nose projecting through the valve seat.  The piston is maintained in the closed position by supply line pressure which is transferred via a bypass timing circuit to a pressure chamber behind the piston where it is sensed by the rear face of the piston.  The pressure chamber of the main valve is connected by tubing to a normally closed remote push button relief valve.  A second length of tubing leads from the relief valve to the supply source at a point downstream of the valve seat.  When the push button of the relief valve is depressed, the relief valve is opened allowing the pressure in the pressure chamber of the main valve to be reduced.  Inlet pressure acting on the front face of the piston forces it off the valve seat and forces fluid out of the pressure chamber out through the remote relief valve.  As soon as the push button is released, the relief valve closes and the timing of the flow period starts.  Inlet fluid flowing through the bypass timing circuit passes through a timing mechanism refilling the pressure chamber at a controlled rate.  The preferred timing mechanism comprises a disc of deformable material which is positioned in a bore in the bypass circuit and has an axial opening through which fluid must pass to reach the pressure chamber and an adjustable member which is employed to selectively exert an axially directed force upon the disc to deform the material of the disc into the axial opening thereby effectively reducing its effective diameter.  The more the disc is compressed the smaller the effective diameter of the disc and the longer the flow period.

Abstract: ABSTRACT      A roof is assembled conventionally from cladding supported by purloins or girders extending between end walls of the building. The cladding is often metal. By providing a single structural spanning member, the requirement for girders or purloins is avoided and construction work is simplified. The usefulness of the structural spanning member is measured by the unsupported span that can be erected when the member is formed from sheeting material of stock width, conventionally with steel 1 or 1.2 metres, of a given thickness and rigidity. This member achieves the desired solution by a novel configuration in which the whole width of sheeting is utilized to form a single member having a top chord spaced from a bottom chord by a strengthened web, wherein pairs of chords of adjacent members nest to provide a single pitch of the roof.

Abstract: Across the screen is a mosaic of spaced phosphor bodies which emit light of different colors when excited by electrons.   Phosphors which emit three different colors, e.g. red, green and blue, are used and are disposed in a regular repetitive array of groups of three, i.e. triads.   In every other triad the phosphor body which emits the color which has the least acuity to the eye, e.g. blue, is replaced by a nonluminescent black material.   The blue phosphor bodies are of a width substantially equal to the width of the penumbra of the electron beam which impinges on the blue phosphor bodies.   The red and green emitting phosphor bodies are of a width substantially equal to the umbra of their corresponding electron beams which is about one-half the penumbra of the beams.  The phosphor bodies are spaced apart such that the portions of the red and green impinging electron beams which do not impinge on their respective phosphor bodies impinge on nonluminescent spaces between the phosphor bodies and the center-to-center distances between adjacent phosphor bodies of like color are equal across the screen.

Abstract: Abstract of the Disclosure Method of recording X-ray images and imaging chamber suited therefor A method and an apparatus are described for making X-ray images by means of an  ionographic imaging chamber.   The  spherical  cap configuration of the electric field necessary to avoid image unsharpness in such a chamber is built-up with only one DC voltage supply. This may be realized by equispa-tially arranging the annular ring electrodes on or in the electrodes of the imaging chamber and by applying DC voltages to such annular ring electrodes which are integers of one basic voltage.  Also the DC voltage over the gap between the electrodes of the chamber may be an integer of the same basic voltage.  In contradistinction with the prior art imaging chambers only one DC voltage is necessary and the spherical cap configuration of the electric field is obtained in a more simple manner.
