Abstract: 1,033,322. Laminates. PITTSBURGH PLATE GLASS CO. Feb. 28, 1964 [March 1, 1963; April 24, 1963; Aug. 2, 1963], No. 8320/64. Heading B5N. Laminates of sheet glass, or of rigid transparent synthetic resin such as acrylic, polycarbonate or polyester resin, having interlayers, e.g. of polyvinyl butyral, contain at least one other component comprising a thermosetting resin reinforced with glass fibre, the resin being e.g. a condensate of formaldehyde with phenol, resorcinol, urea, dicyandiamide, or melamine, or a mixture thereof, and being flexible when uncured and rigid when cured and preferably having a thermal expansion coefficient when cured within the range 0À5-8À0 microinches/ inch/‹ F. The laminates may be used to make road vehicle and aircraft windscreen panels and may contain conductive coatings or grids for heating, connected by leads and bus-bars to terminal blocks; the fibrous components may be used as tapes to enclose and insulate the leads, but may also comprise (i) inserts set in the interlayers close to the edges of the panel to prevent delamination or edge chipping due to differential contraction of layers at low temperatures, (ii) stiffening inserts or frames in the edges of the interlayers, or (iii) protective cover strips for the edges of the panel. In Fig. 2 (not shown) glass plies 5, 7 have between them an interlayer 9 of plies of polyvinyl butyral consolidated by heat and pressure, the interlayer having a frame-like insert 11 of the thermosetting resin-impregnated glass fibre. The ply 5 has a conducting coating electrically connected by a bus-bar 12 and a lead 13 to a terminal block 1, the lead 13 being enclosed between tapes 15 of the resin-impregnated glass fibre, themselves secured to the ply 5 by a rubber latex, " Thiokol " (Trade Mark) or other elastic bonding medium 17. The interlayer 9 extends beyond the plies 5, 7 and is used to secure the panel in its mounting. Constructions showing similar electrical connections and insulating features are described in which (a) the glass ply 7 is extended with the interlayer and (b) the other glass ply is extended, without the interlayer, and comprises several plies bonded together with interlayer material, the terminal block being supported on the extended layers. In Fig. 7 (not shown), inserts 18 of the resinimpregnated glass fibres located in the interlayer 9 near the edge of one or both glass plies 5, 7, are treated with parting material 19 such as regenerated cellulose, a polyester or a polyfluorocarbon to weaken the bond and prevent delamination or chipping, elastic bonding medium 17, which may extend over the edges of the plies, being used to secure the inserts and the parting material. In Fig. 13 (not shown) thermosetting resin-impregnated glass fibres 27 may be used to seal the edges of a stepped or plain laminated panel. The material 27 may extend marginally over the face of the panel and may be secured by bonding medium 17.

Abstract: 903,903. Control of two motors; mercury switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd., and ELCOM Ltd., F. B. March 16, 1959 [March 18, 1958], No. 8603/58. Classes 38 (3) and 38 (5). [Also in Group XXXV] Opposite ends of a platform are lifted by two electric motors, and means responsive to tilting of the platform are provided for controlling the motor operation so as to restore the platform to its horizontal position. The platform is raised by actuating push-button R to energize contactors R1, R2, for operating both motors. Tilting of the platform is detected by a mercury switch MS, inclination of which causes either electrode E2 or E3 to emerge from the mercury pool and interrupt the circuit of the contactor R1 or R2. Thus, the motor which is tending to overtake the other is disconnected until the position of the platform is corrected, whereupon both motors are again energized. Operation during lowering of the platform is similar to that described. As shown, the electrodes E2, E3 comprise plates which form contact areas on the surface of the mercury pool. In another arrangement the electrodes E2, E3 are immersed, and, if two mercury switches are used, the depth of immersion is set to take into account inertia effects to prevent hunting. Each electrode E2 or E3 may be replaced by a pair of point electrodes at different levels and having a switch therebetween to alter the time of response. A further switch may disconnect both motors if the angle of tilt exceeds a predetermined limit.

Filed: 1955-03-25
Abstract: <PICT:0804346/IV (b)/1> <PICT:0804346/IV (b)/2> A continuous sulphonation process is described wherein a liquid sulphonatable material is progressively sulphonated in passing through an apparatus, said apparatus being disposed horizontally and comprising an inner tube surrounded by an outer tube with a space there-between for the passage of a cooling medium, a rotatable shaft with scrapers attached thereto and spaced from the shaft disposed within said inner tube which is contacted by the scrapers and which defines with the shaft and scrapers a reaction chamber having its inlet and outlet at opposite ends, said rotatable shaft having, at points closely in advance of the scrapers, a plurality of passageways through which material can be introduced into the reaction chamber.  The sulphonation process also comprises the features of introducing the liquid sulphonatable material at the inlet under sufficient pressure to maintain a continuous flow between the inlet and outlet and in an amount sufficient to partially fill the reaction chamber, a film of the sulphonatable material being deposited on the cooled surface of the inner tube by means of the centrifugal action resulting from rapidly rotating the shaft, introducing sulphur trioxide with or without an inert diluent through the passageways in the rotating shaft to impinge upon the film of sulphonatable material, the amount of sulphur trioxide introduced at each point being insufficient in itself to effect complete sulphonation, the partially sulphonated material being scraped from the cooled surface of the inner tube and replaced by a further film of sulphonatable material, repeating the partial sulphonation of the sulphonatable material during its progress through the reaction chamber until it is fully sulphonated and collecting the fully sulphonated material as it emerges from the outlet.  Figs. 3 and 4 show cross-sectional and end views of the reaction vessel wherein 12 is the inner tube or cooled surface and 11 is the rotatable shaft having scrapers 10 and inlets 13 for the sulphonating agent from passageway 9.  Specified sulphonatable materials are mono-and poly-dodecylbenzenes, nonylnaphthalene, other alkaryl hydrocarbons of the benzene, naphthalene and diphenyl series, phenols and petroleum oils or solvent extracts from petroleum.  The sulphonatable material used in the process may be a partially sulphonated material or it may be diluted with the sulphuric acid obtained at the end of the process by recovery of the excess sulphur trioxide.  The inert diluent which may be used with the sulphur trioxide may be liquid, e.g. sulphuric acid, or it may be a gas such as dry air, nitrogen, carbon dioxide, sulphur dioxide or a lower alkane.  In examples dodecylbenzene and nonylnaphthalene are sulphonated by the process described using sulphur trioxide diluted with dry air and neutralizing the product with sodium hydroxide. Specification 804,347 is referred to.
