IPC: E04B7/20
Filed: 1938-04-30
Abstract: 500,398. Roofs ; tiles ; metal sheets. YEARSLEY, R. A. April 30, 1938, No. 4644. [Classes (ii), 20 (iv), and 87(i)] A roofing-construction comprises an underroofing of corrugated-metal sheets 7 which are disposed with the corrugations running in the direction from eaves to ridge and are each furnished on the outer surface with regularyspaced projections, indentations or channels adapted for engagement with the nibs of tiles 4 of clay, concrete or the like. The roof shown in Fig. 1 is provided with regularlyspaced projections in the form of transverse battens 15 over which the nibs 5 of the tiles 4 are hooked. The battens 15 may be secured by bolts 17 which serve to connect the adjacent corrugated-metal sheets 7, the bolt holes in the edges of the sheets being appropriately pitched. Each bolt 17 may have a cranked upper end terminating in a nib which is caused to bite into the top surface of the batten 15 ; alternatively, the bolt 17 is adapted to anchor a clip having a curved saddle portion to fit one of the corrugations of a sheet 7 and a cranked portion which overlaps the top surface of the batten 15 and is secured thereto by a nail, screw or prong. The roof shown in Fig. 2 is provided with spaced metal channels 20, 20a for receiving the nibs 5 of the two top courses of tiles 4 ; the next course of tiles is positioned by an angle-strip 21, and the lowermost course of tiles by a channel 22 which has a flange 23 to engage a lug 24 on the underside of the tiles in the next course. These channels and anglestrips may be secured by Aquare-headed bolts which also connect adjacent corrugated sheets 7 and are disposed with their heads on the said strips; alternatively, the bolts 17 may be used to anchor a clip having a saddle to fit over one corrugation of a metal sheet 7 and upstanding lugs which grip a channel strip between them. The roof shown in Fig. 3 comprises asbestoscement sheets 6 mounted on the corrugatedmetal sheets 7 which are secured to the purlins 8 by J-bolts 9 adapted also to secure the sheets 6. The projections for engaging the. nibs 5 of the tiles 4 are in the form of regularlyspaced channels or laths 10 which may be of asbestos-cement and secured to the sheets 6 by cement or other adhesive. The roof shown in Fig. 4 is arranged with each of the upturned tiles 4c in close engagement with a corresponding corrugation in the sheet 7, and the downturned tiles 4d overlie the edges of the tiles 4c. The nibs 5c, 5d of the tiles 4c, 4d are set in bitumen, mastic, or other suitable material in regularlyspaced pockets or indentations 13, 14 provided in the sheet 7. The tiles may be additionally secured to the roof structure by wires which are either passed over the outer faces of the tiles and covered by the tiles in the succeeding course, or engage lugs 12 provided on the underside of the tiles as shown in Fig. 3. Instead of the nibs 5 of the tiles 4 being integral therewith, they may be formed by pegs set in the tiles.

Filed: 1975-02-06
Abstract: 1477944 Cable grommet H SIMON 6 Feb 1975 5027/75 Heading H2E [Also in Division E2] A cable support grommet has a cable carrying passage 5 bounded in part by an intermediate wall 7 which is joined to the body by a resilient web 8. When screw 10 is turned it exerts pressure on wall 7 thereby gripping the cable between said wall and the bottom of the passage 5 and also distorting the grommet so that it is wedged in an aperture (Fig. 5, not shown). Any longitudinal force exerted on the cable is balanced by the component of the force exerted by screw 10 in that direction. The grommet is held in a somewhat oval aperture (Fig. 5, not shown) by rotation of the body through 90 degrees. In another embodiment (Fig. 10, not shown) the grommet is retained in place by two flanges (13, 14) which together are approximately cone-shaped and may be deformed sufficiently to snap into the aperture (Fig. 11, not shown). The intermediate wall (7) has serrations (71) to aid gripping of the wire.

Title: Improvements in or relating to cathode ray display tube apparatus
Inventor: JESTY LESLIE CONNOCK
IPC: H04N9/24
Filed: 1951-03-02
Abstract: 713,641. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 23, 1952 [March 2, 1951], No. 5149/51. Class 39(1) A cathode-ray display tube has a screen structure provided with a grid or pattern of discontinuities adapted when scanned by the beam to provide register signals which occur when the beam strikes the elements of the grid or pattern. In a tube with an aluminized screen fluorescent material may be deposited on the gun side of the screen in a pattern which may be a series of parallel lines, a grid, or a series of radial lines and concentric circles; the light produced when the beam impinges on an element of the pattern is detected by a photo-cell which may be inside or outside the tube and provides the register signals. In a colour television tube comprising a fluorescent layer in the form of coloured strips R, G, B, Fig. 2, covered with an aluminium layer 4, the aluminium layer may be cut away at the green-red junctions 4a and between each gap on the viewing side is provided an opaque strip 5; the light emitted by the exposed material excites one of two photo-cells, one for green light and one for red. In a further embodiment, Fig. 4, a pattern of four different coloured fluorescent materials R, G, B, Y, is deposited on the screen, the two pairs of colours providing register signals for the two scanning directions. The spacing of the strips of a grid or pattern need not be uniform and may be wider at the edges than at the centre. Instead of using fluorescent material a secondaryemitting material may be used and a collecting electrode provided. The register signals produced may be composed with timing pulses in the modulation signal and used to speed up or slow down the scanning when the registration is incorrect.

Abstract: 725,321. Frequency measurement. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 24, 1953 [Feb. 25, 1952], No. 5151/53. Class 37. In a device for supervising the frequencies of a multi-channel system in which the carriers are harmonics of a standard frequency but are not all derived from a common standard frequency oscillator, the output of a harmonic generator HG fed from a standard frequency generator is amplified in a linear amplifier F with one of the carrier currents to be supervised. The output of this amplifier is applied to a biased rectifier circuit (Fig. 1) in which the condenser C bypasses the HF components giving a demodulated signal across R at the beat frequency given by the carrier to be supervised and the harmonic from the standard oscillator nearest to it in frequency, any weak signal having been blocked by the bias voltage which also increases audibility of the beat frequency. The beat frequency is measured in a frequency meter fed by a low-frequency amplifier or aurally observed through a speaker.
