IPC: C07C27/22
Filed: 1969-05-08
Abstract: 1,256,310. Aldehydes and alcohols by oxo process. BADISCHE ANILIN- & SODAFABRIK A.G. 8 May, 1969 [9 May, 1968], No. 23536/69. Heading C2C. Aldehydes and alcoholes are produced by the hydroformylation of olefinically unsaturated compounds with CO and H 2  at elevated temperature and superatmospheric pressure in the presence of a carbonyl complex of a Group VIII metal which has been modified by a trisubstituted phosphine in which two substituents are methyl or ethyl radicals and the third substituent is a C 8-30  aliphatic radical. Suitable unsaturated starting materials are aliphatic, cycloaliphatic and araliphatic compounds of 2-20 C atoms. The catalyst may be a Co or Rh carbonyl modified by methyl ethyl C 12-24  phosphine. The catalyst metal to P ratio is preferably 1 : 1 to 1 : 6. In the example ocetene is hydroformylated using a Co carbonyl catalyst modified with dimethyldodecyl phosphine.

Abstract: 805,330. Gas turbine plant. ROLLSROYCE Ltd. July 20, 1955 [Aug. 13, 1954], No. 23657/54. Class 110 (3). Air pressure is applied to the surfaces of gasturbine discs for axial-load balancing. As described, air from the compressor enters a chamber 25 ahead of the HP disc 10 and passes through ports 32 and bore 34 to a chamber 35 ahead of the LP disc 15. (The pressure in chamber 35 may be e.g. four fifths of the pressure in chamber 25.) Air also leaks through the labyrinth seal 37 to a chamber 39 at the back of the HP disc (where it may be at half the pressure of chamber 35), thus providing a pressure drop across each disc for balancing axial loading due to the compressor. Pressure-air leaks through the outer labyrinth seals 28, 43, 50 to prevent hot gases flowing inwardly.

Filed: 1929-08-03
Abstract: 316,946. Lorenz Akt.-Ges., C., (Assignees of Pohontsch, M.). Aug. 6, 1928, [Convention date]. Magnetic modulating systems; keying systems. - alternating currents, particularly high-frequency currents employed in wireless signalling, are modulated or interrupted by the use of a pair of iron-cored chokes, one in the aerial or load circuit, and the other in an absorbing circuit with similar constants, not coupled to the aerial circuit. As shown in Fig. 3, the generator circuit, which may be energized directly or through a frequency-multiplier from an alternator 1, or by a valve generator, is coupled by transformers 3, 4 to an aerial circuit V and to an absorbing circuit X. Iron-cored choke coils 9, 18 in the respective circuits are saturated in turn, the transmitting key or microphone, being arranged to vary the direct current in these windings. The windings 13, 19 may be arranged in the plate circuits of a pair of valves V1, V2, Fig. 4. For telegraphy, a keying -device or relay R is arranged to render these valves conductive and non-conductive in turn by biasing their grids, the switches U being in the vertical position. For telephony, the switches U are thrown horizontal to couple the grids of valves V1, V2 to the plates of valves V3, V4, the grids of the latter pair being controlled in push-pull fashion by a microphone circuit M. The purpose of the arrangement is to maintain a constant load on the oscillation generator, and so prevent surges and variations of frequency during the keying or modulating operation.

A silicone composition comprises an organopolysiloxane having, as terminal groups attached to the terminal silicon atoms of the siloxane chain, -OH groups or groups which are hydrolyzable to hydroxyl groups in the presence of ambient moisture, and further having a polymeric segment, derived from at least one ethylenically unsaturated monomer, grafted on to the siloxane chain through an organo side group of the chain. When the organopolysiloxane contains -OH groups, the composition is cross-linked by addition of a polyalkoxysilane or polyalkoxysiloxane, e.g. ethyl orthosilicate or decaethyl tetrasilicate, and a catalyst such as dibutyltin dilaurate or dibutyltin butoxychloride. Alternatively, a silane is added to the composition containing -OH groups and the resulting product is hydrolysed by moisture to yield a cross-linked composition. In Examples I to XI, hydroxyterminated polydimethylsiloxane is grafted with styrene and m-butyl methacrylate, vinyl triethoxysilane being present in Examples IX and XI and also n-butyl methacrylate in the latter. The resulting graft polymers are cured with (i) vinyl triacetoxysilane; (ii) methyl triacetoxysilane, in the presence of (a) clay and ground silica; (b) fumed silica and calcium silicate; or (c) fumed silica and ground silica; (iii) partially hydrolysed ethyl silicate and dibutyltin dilaurate; (iv) dibutyltin butoxychloride; or (v) stannous octoate.
