Abstract: 1428610 Pontoons for offshore structures; ballasting pontoons BROWN & ROOT Inc 18 Feb 1974 [25 April 1973] 7281/74 Headings B7A and B7M [Also in Division E1] A steel jacket 20 for an offshore platform is transported from its building dock to the offshore site on a pontoon raft 100 of floatation tanks and upon reaching this site a first set of chambers are flooded so that one end of the raft performs a crash dive to rapidly pitch the jacket 20 from the initial horizontal position to the inclined position in which two spherical buoyancy tanks 260, 262 located on a base portion of the jacket 20 are awash (Fig. 13B) and thereafter further chambers within the tanks constituting the raft 100 and the spherical tanks 260, 262 are flooded to firstly place the jacket 20 in a vertical position and then lower it on to the sea bed. The raft 100 is detached from the jacket 20 by detonating a first set of explosive charges to release connections between the raft 100 and jacket 20 and thereby permit the raft 100 to pivot about pivot connections 236 into a vertical position (Fig. 19B) and then further charges are detonated to fracture the connections 236. The raft 100 is then towed away still in its vertical position until clear of the jacket 20 and then the tanks are vented to raise it into the horizontal position on the surface. Construction of raft.-The raft comprises two mutually inclined floatation members 106, 108 internally divided into chambers 150 by bulkheads 148, two outboard auxiliary floatation members 110, 112 also internally divided into chambers 168 by bulkheads 166, bifurcated floatation members 114, 116 constituted by tubular parts 170, 172, 174, 176 again internally sub-dividedby bulkheads 202, 204 and interconnecting tubular columns 122, 124, 126, 128, 130, 132, and 138, 140, 142, 144, 146. These floatation members and columns are provided with conventional ballasting and deballasting valves, ballast sensing devices and control lines therefor as are aslo the spherical tanks 260, 262. The jacket 20 is connected to the raft by vertical pillars 222 spaced along the length of the members 106, 108 and similar pillars 223 on the columns 122, 124 126, 128, 130 and 132. The free ends of the bifurcated floatation members are interconnected by bridges 230, 232 which carry vertical columns 234 including the pivots 236. The explosive charges surround these pillars 222, 223 and columns 234.

Title: Improvements relating to silicones
Inventor: EMBLEM HAROLD GARTON
IPC: C08G77/06
Filed: 1949-03-17
Abstract: The Specification describes a number of particular methods of preparing organopolysiloxanes using the general method of the parent Specification in which the siloxane links are built up by reaction of molecules containing halogen directly bonded to silicon with molecules containing alkoxy or aroxy groups directly bonded to silicon with elimination of alkyl or aryl halide.  The Specification describes the use of (a) compounds containing three halogen or alkoxy or aryloxy groups; (b) silicon tetrachloride; (c) ethyl orthosilicate; (d) compounds containing both halogen and alkoxy or aryloxy groups attached to the same silicon atom; (e) partially polymerized, i.e. partially hydrolysed and condensed halogeno- or alkoxy or aryloxy silanes, and the carrying out of the reaction with the addition of a small quantity of water insufficient to cause substantial hydrolysis of the reactants.  In the last case the effect is similar to the use of partially polymerized reactants.  In examples: (1), (2), (6) and (7), silicon tetrachloride and a partially polymerized ethoxy ethyl silane are condensed; (3) and (8) diethyl silicon di-chloride and a partially polymerized ethoxy ethyl silane are condensed; (4) and (9) diphenyl silicon dichloride and a partially polymerized ethoxy ethyl silane are condensed; (5) and (10) a mixture of ethoxy methyl silanes and methyl chlorosilanes are condensed in ether and acetone containing a small quantity of water; (6) phenylmethylethoxychlorosilane is self-condensed.  Catalysts referred to are aluminium, ferric and zinc chlorides. Specifications 290,717, [Class 1 (i)], and 609,841 also are referred to.

Abstract: 766,891. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 25, 1955 [March 12, 1954], No. 7328/54. Class 38(3) In a system for operating two or more dynamo-electric machines in mutual synchronism, a polyphase-wound receiver machine B, b, is started from standstill and accelerated into synchronism with a polyphase-wound transmitter A, a. Two terminals of the primary winding A of the transmitter are short-circuited, and the primary windings A, B, are connected to a single-phase supply. With the transmitter machine in operation, the machine B, b is started by closing switch S1 to interconnect the secondary windings, and switch S2 is engaged with contact 1, thus connecting impedence Z in series with one phase of the winding B. The controlled machine will thus accelerate and automatically synchronize with the controlling machine, whereupon, the switch S2 is changed over to the contact 2 to short-circuit two of the terminals of the winding B and to provide symmetrical connections for the machines. The impedance Z may consist of a resistor, capacitor, or choke, or any combination thereof. In another arrangement, the connection of the primary windings of the machines to the single-phase supply is provided by a contactor having its operating winding controlled by a push-button switch. A contact of the control switch alternatively completes a circuit for the operating winding of the contactor of forms a short-circuit across two phase windings of the controlled machine, Fig. 2 (not shown). In the latter embodiment, the switch S1 is omitted. The windings of the machines may be delta-connected. Impedance may be connected in each phase of the controlling machine to cause the ratio of the synchronised torque to the motoring torque of the controlled machine to be maintained at a high value during the accelerating period.
