Abstract: 924,069. Roads &c. surface treatment. RELIANCE STEEL PRODUCTS CO. May 5, 1959 [Oct. 30, 1958], No. 15413/59. Class 107. To form the wearing surface of a road &c., proportioned amounts of an epoxy resin and catalyst therefor are brought together, preferably in presence of a diluent for the resin such as a resinous or semi-resinous hydrocarbon, and mixed immediately prior to being spread on the road. Abrasive grains in excess of the amount the resin can wet are applied and the unattached grains removed. The resin cures in situ. As shown, Fig. 2, a tank truck comprises longitudinal compartments containing an epoxy resin/pine oil mix and a catalyst road oil mix respectively heated by flues 48. Pumps 53, 54, preferably driven at equal speeds by motor 64, force the respective mixes via valved outlets 55, 57, pipes 60, 62 and meters (not shown) to vertical pipes 68, 73, leading to a mixing column 71 which comprises a casing fitted with baffles or metal shavings. The fluid, further mixed in a trough 75 by a spiral agitator 76, is pumped to a spray pipe 84 by a pump 82 linked to the pumps 53, 54. The final mix comprises in parts by weight: epoxy resin, 100; road oil, 90; pine oil, 10; catalyst 14. The three-way valves 56, 58 enable the mixes to be recirculated around their respective pumps through by-pass lines (not shown). A third smaller compartment on the truck contains solvent which is circulated by pump 54 to flush out the system at the end of a run. A spreader device on a truck hitched to the back of the tank truck but travelling in an adjoining lane of the road distributes abrasive grains in excess of the amount which the newlylaid coating can contact. The surface is then rolled and the excess of unattached grains brushed off and re-used. In another embodiment shown diagrammatically in Fig. 6, compartments 101-104 contain resin, road oil witn or without pine oil, catalyst and solvent respectively. Resin and road oil pass through a common pipe 115 in which are one or more packed columns and which discharge into a mixing column 125. The catalyst is pumped through proportional feed pump 120 linked to the pump for the resin and road oil to enter the upper part 117 of the mixing column in counterflow to the incoming fluid from the pipe 115.

Filed: 1939-05-30
Abstract: 529,410. Photo-electric cells. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 30, 1939, No. 15964. Convention date, May 31, 1938. [Class 39 (i)] A television transmitting tube has a mosaic electrode and a photocathode adjacent to and substantially coplanar with each other and means for scanning the mosaic with a beam of electrons from the photocathode. In the form shown in Fig. 1, an optical image of the object 5 is focused on to a single-sided mosaic screen 4, the back coating 15 of which is earthed at 16 and connected to a triode amplifier 17. The scanning pattern on the fluorescent screen of a cathode-ray tube 8 is focused at 9 on to the earthed photocathode 7 and the two electrodes are separated by a coarse mesh accelerating electrode 10 (or in its place a ring electrode) which is maintained slightly positive with respect to earth. A focusing coil 12 of diameter equal to or greater than the maximum distance between the remote edges of the electrodes 4, 7 produces a substantially semicircular field, as shown in dotted lines, which intersects the electrodes 4, 7 normally to their surfaces. A recess 11 in the tube receives the coil so as to give this normal intersection. The slow velocity electrons emerging from the photo-electric layer 19 under the action of the scanning beam of the tube 8 form in effect a record scanning beam and are directed by the electrode 10 on to the mosaic 4, giving signals in proportion to the intensity of the image of the object 5. Since any low velocity electrons from the photocathode reach the mosaic, "dark spot" signals are not produced, and the coplanar disposition of the two electrodes 4, 7 precludes light from the flying light spot from reaching the mosaic. Fig. 2 shows a form in which the mosaic and photocathode 4, 7 are placed over a common flat part of the tube above the poles of a horse-shoe electromagnet 20.
