Patent GB-914053-A (GB)
Title: Process for the preparation of hydrocarbon compounds of aluminium and of ª--olefins
IPC: C07C29/54
Filed: 1961-04-17
Abstract: Metallic aluminium, hydrogen and an olefine with a non-terminal double bond are reacted together at elevated temperature under pressure to give a hydrocarbon aluminium compound containing secondary or tertiary alkyl residues, and if desired, this product may be rearranged at elevated temperatures to a compound having primary alkyl residues.  This compound containing primary alkyl residues may in its turn be split at elevated temperature under conditions such that the olefine split off is quickly removed from the reaction mixture.  Olefines specified include 2-butene, 3-pentene, 3-heptene, 4-octene, 4-nonene, 5-decene, 3-dodecene, 4-dodecene, 6-dodecene, 6-hexadecene, 7-hexadecene, 9-octadecene, 10-eicosene, 14-octacosene, and mixtures obtained in the Fischer-Tropsch synthesis or in the catalytic cracking of petroleum. The presence of paraffins in these mixtures has no detrimental effect on the reaction.  a -olefines which may be present react more rapidly than the olefines with a non-terminal double bond, and they may be reacted first, the unreacted hydrocarbon mixture being distilled off and used according to the process of the invention.  The aluminium, preferably comminuted may be activated in known manner by such compounds as alkylaluminium compounds, alkyl halides or alkylaluminium halides. Organic aluminium compounds may be used as catalysts.  The reaction may be conducted at a hydrogen pressure between 100 and 300 atmospheres and 90 DEG -150 DEG C.  The conversion to organic aluminium compounds having primary alkyl residues may be carried out between 160 DEG  and 180 DEG C. in the presence of stabilizers such as the olefines with nonterminal double bonds used as starting materials.  The third stage, (splitting off of olefines) may be carried out between 150 DEG  and 300 DEG C. using nitrogen, argon or other inert gas as entrainer to remove the olefin formed rapidly from the reaction zone.  This pyrolysis reaction may be promoted by the presence of small quantities of aluminium powder or aluminium shot.  Specification 913,358 is referred to.

Abstract: 725,871. Controlling aircraft. MOORE, J. D., WOOD, B. S., and ROE CANADA, Ltd., A. V. May 16, 1953, No. 13786/53. Class 4. An aircraft control system includes a normally manually operable lever having restraining means coupled thereto for restraining free manually controlled movement of the lever, releasing means coupled to the restraining means and actuated when it is desired that the restraining means should be released from the lever, and a remotelycontrollable apparatus adapted to operate the lever on the closure of a switching means, the switching means being also arranged simultaneously to release the restraining means. A normally manually operated throttle lever 11 may have its free movement restrained by operation of a lever 12 which is held in its restraining position by a spring loaded rod 15. Axial movement of the rod under the action of the spring is prevented by a two-part lock 16, the locking bolt being movable in the direction of the, arrow to free the rod 15 by a solenoid 17. A remotely controlled servomotor 18 may be energized to operate the lever 11 and to this end the unit 18 and the solenoid 17 are coupled in parallel to a source of electrical energy 19 through a switch 20. Closure of the switch energizes the solenoid to release the rod 15, and to remove restraint to movement from the lever 11, which is then free to be operated automatically by the energized unit 18.

Abstract: 636,868. Gas turbine plant. JANES, R. May 25, 1948, No. 14172. [Class 110(iii)] An arrangement for extracting gas from the exhaust of a gas turbine has a portion of the exhaust duct defining wall formed with its leading edge spaced into the duct away from the adjacent part of the duct defining wall to form a gap leading to a collector chamber which increases in cross-sectional area from its inlet to its outlet so as to convert the velocity of the extracted gas into pressure. The exhaust passage 11 is formed between a conical fairing 15 and an outer wall consisting of a double-skinned structure 12 and a frustoconical sleeve 13. The upstream edge 13a of the sleeve 13 is spaced from the structure 12 by locating pins 33 to form an annular gap 13b leading to a collector chamber 18. The continuation wall 12a of the structure 12 diverges from the sleeve 13 so that the chamber 18 has a gradually increasing cross-sectional area. The downstream end of the wall 12a carries a ring 14 having a cylindrical extension 14a which cooperates with a spherical-surfaced ring 19 mounted on the end of the sleeve 13 to form a gas seal between the chamber 18 and passage 11 and to permit expansion of the sleeve. The outlets from the chamber 18 are controlled by means of butterfly valves operated by hydraulic rams. To ensure that the valves are fully closed, one end of each ram is connected to the valve and the other to a rocking lever arranged to load a compression spring by additional travel of the ram after the valve reaches its fully closed position. Specification 619,390 is referred to.

Title: Nitrogen-containing thioesters
IPC: C07D277/74
Filed: 1966-03-30
Abstract: Novel thioesters of cyanoformic acid of the formula NC-CO-SR, where R is an optionally substituted aliphatic hydrocarbon, aromatic hydrocarbon or aralkyl group, or a 2-thiazole, 2-benzthiazole or 2-benzimidazole group, are prepared by the acid hydrolysis of a cyanoformimido acid thioester of the formula NC-C(=NH)(-SR), preferably in an aqueous reaction medium at a pH below 6.  The hydrolysis may be effected with a mineral acid, e.g. HCl or phosphoric acid, or with an organic acid. The reaction may be applied to the preparation of thioesters of cyano-formic acid generally, and may be carried out between 0 DEG  and 100 DEG  C. in aqueous medium, the product being subsequently extracted with an organic solvent, or may be effected in a two-phase system, one phase being an aqueous acid phase and the other being a water-immiscible organic solvent. Suitable solvents are ethers, aromatic and aliphatic hydrocarbons and chlorinated hydrocarbons. The substituents which may be present when R1 is aliphatic or aromatic may be halogen, OH, OR11, COOH, COOR11, CONH2 or SR11, wherein R11 is C1-C8 alkyl, or the substituent may be NR111R1111, in which R111 and R1111 are C1-C8 alkyl or together with the N atom represent a heterocyclic ring.  The products are useful as intermediates and as pest control agents.  The starting cyanoformimido acid thioesters are prepared by the reaction of dicyanogen with the appropriate mercaptan.  The reaction may be carried out in the presence of magnesium, aluminium, or heavy metal compounds such as cadmium acetate as catalyst, or in the presence of an excess of dicyanogen and an organic amine, quaternary ammonium salt or alkali metal compound as catalyst.ALSO:Cyanoformic acid thioesters of the formula NC-CO-SR, where R is an unsubstituted or substituted aliphatic hydrocarbon, aromatic hydrocarbon or aralkyl group, or a 2-thiazole, 2-benz-thiazole or 2-benzimidazole group, are useful as pest control agents.  They may be used, e.g. as 0.5% solutions in mineral oil, for the destruction of mosquito larvae in water, or, as 0.5% aqueous emulsions which may contain emulsifying agents, for spraying, and act as contact-, stomach- or respiratory poisons.
