IPC: G05G7/10
Filed: 1958-04-15
Abstract: 873,990. Ultrasonic inspection devices. KELVIN & HUGHES Ltd. April 14, 1959 [April 15, 1958], No. 12009/58. Class 40(7) [Also in Group XXIV] An arrangement of gearing for positioning the probe of an ultrasonic inspection device, in three dimensions comprises a control box 13, Fig. 2, coupled by Bowden cables A, B, C to the probe adjusting mechanism, Figs. 3 and 4, supported on a bracket 21a. The probe 10 is fixed to a horizontal spindle 11 which is rotatable in a bracket 12 to vary the angle of elevation or tilt of the probe in relation to the workpiece. This rotation is effected through gearing 38-41 from a shaft 34 geared at 32, 33 to a spindle 31 carrying a drum 30 actuated by the cables A. The bracket 12 is rotatable as a whole about the vertical axis to vary the bearing of the probe by a concentric tubular shaft 35 geared at 60, 61 to a spindle 59 carrying a drum 58 actuated by the cables C. The height of the probe is adjusted by movement up or down of another tubular concentric shaft 22 carrying the bracket 12 and the elevation and bearing adjusting mechanisms. This is effected by a pinion 20, operated by the cables B on a drum 19 and supported on the bracket 21a, engaging rack teeth on the shaft 22. This vertical movement through the cables B is effected at the control box 13 by a handwheel 14. Both elevation and bearing of the probe is effected by a handwheel 15. For elevation the handwheel 15 drives the drum 29 for cables A only but if bearing adjustment is required a knob 50 of layshaft 45 carrying gears 47, 53 must be pulled out from the position shown in Fig. 2 to mesh gear 53 with a gear 56 on spindle 28 of knob 15. Gear 53 also meshes a gear 55 on a spindle 44 carrying a drum operating the cables B. Rotation of the probe bracket 12 is thereby effected together with a compensating movement from the elevation drum 29 and cables A to maintain the elevation the same owing to the action of gear 39 rolling around gear 38. A differential 78 is provided between the spindle 28, gear 47 and an elevation indicating disc 42 so that this compensating movement of the elevation mechanism does not move the disc 42 whilst elevation adjustments alone do. Height and bearing indicator discs 25 and 69 are also provided. In a modified arrangement separate spindles are provided at the control box for the bearing and elevation adjustments and a differential incorporated in the probe adjusting mechanism to compensate the elevation on bearing adjustments. Specifications 845,797 and 865,573 are referred to.

Abstract: A pressure-sensitive adhesive tape or sheet having a hydrophilic backing, has a primer coating thereon comprising at least one elastomer and a titanate having the formula <FORM:0861215/IV (a)/1> wherein R, R1, R11 and R111 are all alkyl radicals, and on the primer coating is a coating of a compatible normally tacky and pressuresensitive adhesive.  The elastomer may consist of polyisoprene such as milled crude rubber, or a copolymer of butadiene and a monovinyl monomer such as styrene comprising at least 40% by weight of butadiene.  The preferred titanate is either tetra-isopropyl or tetra-n-butyl titanate, but tetra-ethyl, tetra-pentyl, tetra-decyl, or tri-isopropyl-n-butyl titanate are mentioned as alternatives.  Preferably the primer composition is prepared by dissolving a milled elastomer or mixture of elastomers in an organic solvent, and adding one part by weight of the titanate per 1 to 100 parts of elastomer.  In the manufacture of the adhesive tape or sheet the composition may be applied to a hydrophilic tape or sheet as a coating of about 0.01 to 0.25 ounce dry weight per square yard, and dried for a short period at moderate temperatures.  A pressure-sensitive adhesive compound may then be applied to the primed sheet or tape as a coating of about 0.5 to 5 ounces per square yard.  The organic solvents in the primer and adhesive compositions are preferably the same or compatible.  Both compositions may be applied to the sheet or tape by spraying, printing, knife coating, or reverse roll coating.  The sheet or tape may consist of a film of regenerated cellulose, hydroxy alkyl cellulose ether, methyl cellulose, or a hydrophilic ethyl cellulose.  In one of the described examples the primer composition is prepared by dissolving milled pale crepe rubber in toluene, and adding to the solution 0.5 parts by weight of tetra-isopropyl titanate per 99.5 parts of rubber.  The primer composition is applied to a sheet of "Cellophane" (Registered Trade Mark) and is dried.  There is then applied a pressure-sensitive adhesive composition comprising (in parts by weight) milled pale crepe 100, polybetapinene resin 75, petroleum oil 5, and polymerized trimethyl dihydroquinone 2, as a solution in heptane.  In a further example the primer composition comprises 90 parts butadiene-styrene copolymer, and 10 parts tetra-butyl titanate, and in other examples it contains various proportions of pale crepe and tetra-isopropyl or tetra-butyl titanate.  Three other pressure-sensitive adhesive compositions B, C and D are described, viz., solutions in toluene of (B) milled smoked sheet 100, zinc oxide 50, dehydrogenated rosin 75, sym. dibeta naphthyl para-phenylene diamine 2. and lanolin 100; (C) butadiene-styrene copolymer 50, smoked sheet 50, ester of hydrogenated rosin 50, polybetapinene rosin 16, polymerized trimethyl dihydroquinoline 2, and petroleum oil 20, and (D) polyvinyl ethyl ether resin 100, hydrogenated rosin 5, phenyl alpha-naphthylamine 0.35, and polyethylene glycol ricinoleate 1.5.
