Title: Pontoon bridges
IPC: E01D15/14
Filed: 1931-04-08
Abstract: 368,554. Bridges. TOURCHETTE, J. H., 1557, West 8th Street, Oakland, Cali. fornia, U.S.A. April 8, 1931, No. 10403. [Class 20 (i).] A pontoon bridge is so arranged that the road level is maintained approximately level for varying conditions of tide. Two forms are shown, one, Fig. 1, in which the span is relatively short and the upper and lower bridge members are arranged to diverge from the centre of the span to the towers 11 so as to form a rigid structure against vertical distortion, while the other, Fig. 2, shows the arrangement for longer spans, the upper and lower bridge members being disposed parallel there being no arrangement to prevent vertical distortion. The bridge sections 15 .. 19 are each supported on bases 32, which are provided with aprons 38 adapted to be guided by rollers 41 in recesses 39 disposed at the centre portions of pontoons 36, interacting pistons and cylinders 34, 35 being disposed on the bases and pontoons respectively. The cylinders are connected to an accumulator 73 and the relative levels of the pistons and cylinders is maintained by means of compressed air supplied from a tank 55 through a non-return valve 66 and hand-operated valve 56 to a manifold 54 connected by pipes 53 to chambers 51 disposed under the cylinders and to which they are connected by depending pipes 52, Fig. 9. A stop valve 81 and safetyvalve 59 are disposed in a parallel connection between the non-return valve 66 and the manifold 54 which renders the pneumatic control of the hydraulic support for the bridge automatic according to the varying heights of the tide in a bridge constructed to withstand vertical distortion as in Fig. 1. As the tide falls the pontoons fall and the pressure of the pistons on the water in the cylinders is less, so that the pressure in the compressed air system tends to become less, so that the one-way valve 66 opens and the air pressure is maintained from the accumulator 55 and more liquid is forced into the cylinders and the pistons are again supported. As the tide rises the reverse action occurs and the excess pressure of air is relieved by the automatic opening of the blow-off valve 59. The hand-operated valve 56 is closed for the automatic control. For bridges of the type shown in Fig. 2, the automatic control may be effected through float mechanism operating in reference to a fixed point on the shore or on the bed of the river. Indicators for levels and gauges for pressures are supplied on the various components of the systems. The pontoons are supplied with ballast tanks 42 whereby their levels may be adjusted and they are shaped to provide as little resistance as possible to the flow of water past them and are connected together by chains 45 which are at a sufficient depth to allow of the passage of shipping. The pontoons may be surrounded by floating bulkheads 47.

Title: Improvements in the manufacture of metal billets, blooms, ingots or the like and theproduction of hollow bars therefrom
IPC: B22D7/04
Filed: 1928-04-05
Abstract: 320,316. Gordon, F. F. April 5, 1928. Tubes; cased forms. - Billets, blooms, ingots &c. for the production of hollow bars or tubes are made by casting molten metal round a metal core which is capable of subsequent withdrawal by reason of its being of such a character that it will not weld to the metal cast round it and which will elongate more or less uniformly if stretched for removal from the blank thus enabling it to be withdrawn intact. The crosssectional area of the blank may be predetermined so that the quantity of molten metal will not be sufficient to heat the core to welding temperature. For immediate or subsequent finishing the blank into a hollow bar it is forged, rolled, drawn &c. so as to elongate it and the core removed by stretching. The blank may be first reduced into a smaller blank prior to subsequent reducing. Such a core may consist of manganese or austenitic steel, a suitable austenitic steel containing about 0.1 per cent of carbon, 16 per cent of chromium and 12 per cent of nickel. Another core may be of steel containing from 18 to 40 per cent of nickel, or other alloy steel, or a low carbon steel. To prevent the core adhering to the billet it may be coated with graphite, graphite and clay or magnesia or other refractory material. The core may have a metallic layer which welds to the blank during casting. Such layer may consist of high or low carbon steel, non-corrosive metal or alloy such as rustless steel or iron, preferably containing chromium, or chromium and nickel, or chromium nickel and copper, or chromium, nickel, copper and silicon. Other ferrous alloys may also be used or non- ferrous metals or alloys such as nickel. One layer may consist of steel containing 25, 33, or 40 per cent of nickel. Casting may be performed upwards by apparatus as described in Specification 188,201.

Title: Process of making cellulose acetate
IPC: C08B3/28
Filed: 1930-04-02
Abstract: To improve the condition of precipitated cellulose acetate an acetylating mixture is employed containing a liquid which boils above atmospheric temperature, is immiscible with the liquid precipitating-bath, and is inert to the acetylating agent, the mixture being introduced into the bath heated to a temperature at or above the boiling point of the volatile liquid.  The volatile liquid is associated with a limited quantity of acetic acid. Ethylene chloride, chloroform, and trichlorethylene are suitable liquids.  In an example, cotton fibre is pretreated with glacial acetic acid containing a mixed catalyst composed of sulphuric acid and orthophosphoric acids; excess of liquid is then removed by pressing or centrifuging to bring the ratio of acetic acid to cellulose approximately 1/1 , after which is added a mixture of acetic anhydride and ethylene chloride, and esterification effected at a temperature between 33-55 DEG  C.  The reaction mixture is introduced into a bath of water at a temperature near the boiling-point whereby the ethylene chloride is almost instantly evaporated and the cellulose acetate is precipitated in a porous or flocculent form. The ethylene chloride is condensed and separated from any water for re-use.  Specification 345,235 is referred to.
