As shown in Fig. 1, sheets 3 of bituminized fibreboard are laid in a floating manner on a layer 2 of sand and the covering 5 of linoleum, tiles, rubber, wood or synthetic plastic is attached by cementing to the layer 4 of hardwood, fibreboard or other organic or inorganic material. The'sheets 3 have a roughened under-surface to create a frictional resistance on the sand, and the layer 4 has a rough upper surface to ensure good adhesion of the covering 5. In modifications, (a) the insulating layer 3 is applied directly to the supporting member 1 and the layer 4 may be of asphalt which is resilient or rendered unimpressible by a solid filler, and (b) the layer 4 is of resilient bitumen or asphalt sheets or webs rendered unimpressible by quartz sand granules applied directly to a bituminized paper layer 3. The sheets comprising the layer 4 may be inter-connected by chamfering and cementing together the edges thereof. A layer 4 of asphalt or bitumen may be rendered resilient by the addition of a synthetic material such as a phenolic resin or resin and be combined with a backing of sand-paper, synthetic resin such as a polyvinyl chloride foil, or textile material; also, materials, such as wood, glass ceramics, metal or synthetic materials in the form of granules, waffle or lattice or grid-type structures may be embedded in the layer.

Abstract: 1443562 Electron microscopes ONTARIO RESEARCH FOUNDATION 14 Aug 1974 [14 Aug 1973] 38483/73 Heading H1D [Also in Division H4] In a scanning electron microscope for producing stereo signals, whereby the specimen may be viewed stereoscopically, and in which the electron beam is, as shown in Fig. 3, deflected in sequence in opposite directions to pass through an aperture 11 and subsequently impact the specimen 12, and the scanning system scans the beam across the specimen in a plurality of adjacent parallel lines and receives, in addition to the line scanning waveform, a square wave which, for one set of lines-e.g. one line, or the set of odd lines, or one frame-changes the effective angle of the scanning beam with respect to that for another set of lines-e.g. an adjacent line, or the set of even lines, or an adjacent frame, respectively (compare beams 19a, 19b and 20a, 20b of Fig. 3, for example)-the square wave is additionally applied to a further deflection device between the aperture and the specimen-coil 21 in Fig. 4-to ensure that at any given point of the scan, for both sets of lines the beam is incident upon the specimen at the same point, Fig. 4. An amplifying or attenuating device included between the square wave generator and coil 21 permits accurate adjustment of this convergence of beams 19 and 20 at the specimen. The normal line scan waveform may be applied to coils 13 and/or coil 21, or to additional coils (not shown); an amplifying or attenuating device included between the line scan waveform generator and coil 21, and suitably varied during scanning, can keep constant the angle incidence of the beam on the specimen as the point of impact moves towards the microscope axis, thereby keeping the angle of view constant. Electrostatic rather than electromagnetic deflection may be employed; in the latter case, provision is made for permitting slight relative rotation of the fields of coils 13 and 21, either by mechanical rotation of one or other of the coils, or electrically by the use of quadrupole deflection coil systems to permit adjustment of the vertical convergence of the beams despite the spiral path they pursue below the aperture 11. A variety of methods of displaying the stereoscopic image are described (see Division H4).

A gripper device 40 pulls tufts from successively presented spools 16 and then rotates through 90‹, and in doing so, bends the tufts against a cam surface 75 to the U-formation, and then pushes the bent tuft against the backing 2, which has been previously coated with adhesive. A tuft rake 76, Figs. 6 and 7, is actuated to cover and protect the previously deposited tufts while the next row is being applied. The gripper device 40 is pivotable on a shaft 48 which is movable vertically by a cam 70 to pull tufts out from the spools, and horizontally by a pneumatic cylinder 68 to deposit the tufts on the backing after rotation of the gripper device. The spool from which tufts are being withdrawn is locked in position by an arm or arms 30 having a notch 29 which is raised to engage a projection 28 on the spool yarn guide. The gripping device 40 has two gripper bars (41, 42) Fig. 2 (not shown) extending across the width of the machine, and one of which (41) about which the tufts are bent into the U-shape, extends further from the gripper axis (45) than the other (42) to prevent bar (42) touching the adhesive on the backing. The adhesive is cured by heaters 10. The tufts may be bonded to the backing by ultra-sonic welding, in which case gripper bar 41 acts as an electrode. The backing sheet 2 may be hessian. A Jacquard device may provide for programmed selection of desired colours to make the pattern.
