Title: Improvements in or relating to aircraft instruments
IPC: G05D1/00
Filed: 1962-04-24
Abstract: 965,308. Aircraft instruments. M. E. H. GRANT. July 16, 1963 [April 24, 1962], No. 15617/62. Heading B7W. An instrument for use during the landing or take-off run of an aircraft, indicates when the acceleration or deceleration falls below a reference value determined by the time or distance elapsed from the beginning of the run. The speed may similarly be compared with a reference speed. In the Figure, a mechanical differential 25 has one input shaft 18 positioned in accordance with the indicated airspeed detected by a device 15. The other input shaft 24 is rotated at a rate corresponding to a programmed acceleration by a constant speed drive 21 through cam mechanism 23. The output shaft 26 is connected to a switch 28 through a one-way ratchet device 27. As long as shaft 18 rotates faster than shaft 24, the ratchet device 27 slips. As soon as shaft 18 rotates more slowly than shaft 24,.the direction of rotation of shaft 26 reverses, the ratchet 27 engages, and switch 28 operates an indicator 29 to give a visual or audible warning to the pilot. Similarly, a differential 32 is used to compare a programmed speed with ground speed derived from a generator 11 on the nose wheel. Different settings of a gear box 22 and cam mechanism 23 are used for monitoring take-off and landing. The accelerations may be compared electronically. Ground speed may be measured by the Doppler frequency shift of a beacon on the ground.

Patent GB-786020-A (GB)
Title: Organopolysiloxane nitriles
IPC: C07F7/18
Filed: 1956-05-22
Abstract: The invention comprises polysiloxanes of the formula: <FORM:0786020/IV (a)/1> wherein R1 is CH3 or H, n has an average value of 1 to 3, and R is a monovalent hydrocarbon radical free from aliphatic unsaturation.  They may be prepared by (1) reacting the corresponding unsaturated nitrile with a silane of the formula RSiHCl2 in the presence of platinum dispersed on charcoal, and then hydrolysing; or (2) condensing a chloromethylalkoxysilane with an ethyl cyanoacetate in the presence of sodium, hydrolysing and decarboxylating the product to give a cyanoethyl siloxane. Copolymers containing 0.1 to 99.9 mol. per cent of the above units, the remainder being units of the formula R11mSiO 4-m/2 , where R11 is a monovalent hydrocarbon radical, may be prepared by cohydrolysing the corresponding chlorosilanes or by catalytic interaction of the siloxanes.  In the above formul , R may be alkyl, cycloalkyl, aryl or aralkyl.  R11 may be similar and also includes alkenyl radicals.  The polysiloxane nitriles form rubbers when vulcanized with, for example, peroxides; combinations of alkyl polysilicates with carboxylic acid salts; combinations of hydrogen-containing siloxanes and carboxylic acid salts; or, when the siloxane contains alkenyl groups, sulphur with or without accelerators.  Fillers may also be incorporated, e.g. silica aerogel, fume silicas, diatomaceous earth, titanium dioxide, clay, zinc oxide, ferric oxide and crushed quartz.  In the examples: (1) the compound MeSi(Cl)2(CH2)4CN is prepared from CH2 = CHCH2CH2CN and MeSiHCl2, and is hydrolysed to a syrupy polysiloxane of unit formula NC(CH2)4Si(Me)O.  This is copolymerized with an equimolecular amount of octamethylcyclotetrasiloxane; (2) the compound (EtO)2 SiMeCH2C.(CN).HCOOEt is prepared by refluxing chloromethylmethyldiethoxysilane with ethyl cyanoacetate in ethyl alcohol containing sodium.  This is hydrolysed with KOH in ethanol, the ethanol is removed and the siloxane neutralized with HCl.  This is decarboxylated by heating at 185 DEG  C. to give a rubbery siloxane of unit formula NC(CH2)2Si(Me)O; (3) the compound NC(CH2)3SiMeCl2 is prepared from MeSiHCl2 and allyl cyanide, and is hydrolysed to a viscous siloxane NC(CH2)3Si(Me)O; (4) NC.CHMeCOOEt is used instead of the ethyl cyanoacetate in Example (2) and a polysiloxane NC.CHMeCH2Si(Me)O is obtained; (5) PhSi (Cl2)(CH2)4CN is prepared from PhSiHCl2 an CH2 = CHCH2CH2CN, and is hydrolysed to a viscous siloxane NC(CH2)4Si(Ph)O.  This is reacted with 0.01 mol. per cent of hexamethyldisiloxane in the presence of Me3SiOK to give a liquid trimethylsilyl end-blocked polysiloxane; (6) a resinous copolymer of NC(CH2)3 Si(Me)O, monovinylsiloxane, octadecylmethylsiloxane, phenylmethylsiloxane and monomethylsiloxane is obtained by hydrolysis of the corresponding chlorosilanes.

IPC: C07F9/00
Filed: 1963-04-23
Abstract: An improvement of the process of the parent Specification involves reacting an alkali- or alkaline earth-metal in highly reactive form with a tantalum or niobium salt, an ether, which is also a solvent for the reactants, and carbon monoxide under a pressure between 3000 and 8000 p.s.i., at a temperature between 60 DEG  and 150 DEG  C. and in the presence of a catalyst selected from iron, ruthenium or osmium, or the oxides, halides, or carbonyls of these metals, or mixtures thereof.  The alkali- or alkaline earth-metal employed as a reductant is generally employed in at least a 50% excess over that theoretically required to reduce the Group Vb metal salt to a valence state of minus one.  The ether may be a cyclic or straight chain ether, and is preferably a tridentate ether. About 5-20 parts by weight of ether per part of the metal are generally used. The catalyst is used in amounts equivalent to 0.01 to 30% by weight of the tantalum or niobium salt (expressed as weight of free iron, osmium or ruthenium metal).
