Title: Process for the production of cis, trans-conjugated dienes
IPC: C07C51/09
Filed: 1964-02-07
Abstract: Cis, trans-conjugated dienes of general formula <FORM:1004959/C2/1> where R represents -COO-alkyl, -COOH, -CH2OH or -CH2O Acyl, m is 0 to 12, and n 4 to 12, and m + n 4-16 are prepared by reacting a triaryl phosphonium halide,  [Ar3P-CH2-(CH2)n-R1]+X-where Ar is a phenyl radical, R1 is -COO Alkyl or -CH2O Acyl, and X is Cl, Br or I with a proton acceptor to produce a phosphorane Ar3P = CH-(CH2)n-R1 and reacting with an aldehyde <FORM:1004959/C2/2> If R1 represents -COO Alkyl the acid R1= -COOH is prepared by alkaline hydrolysis, and the alcohol -CH2OH, is then prepared by reduction with a complex metal hydride, e.g. lithium aluminium hydride, or alternatively by direct reduction or alkaline hydrolysis of the compounds when R1 is -COO Alkyl, and -CH2OAcyl respectively. The reaction takes place at a temperature of between - 10 DEG  C. and 40 DEG  C., preferably in an anhydrous solvent, with an alkali metal or alkaline earth metal alkoxide or amide as proton acceptor.  The products are purified by fractional distillation and the trans-trans dienes separated from the product by fractional crystallization, or in the form of urea or thiourea addition compounds.  Examples describe the preparation of 10-cis, 12-trans hexadecadiene-1-oic acid, alcohol, and methyl ester, 11-cis, 13-trans-heptadecadiene-1-oic acid, alcohol and methyl ester, pentadeca-11,13-diene-1-oic acid methyl ester, 10-cis, 12-trans-tetradecadiene-1-ol, 10 - cis, 12 - trans - octadecadien-1-ol, and octadeca - 10,12 - diene - 1 - oic acid methyl ester, 9 - cis,11 - trans - pentadecadien - 1 - ol and pentadeca - 9,11 - diene - 1 - oic acid ethyl ester.  The cis,trans-diene products are used as insect attractants and exhibit an anticatabolic activity.  The triaryl phosphonium halides of general formula [ArP = CH-(CH2)n-R1](+)X(-), are prepared by reacting a triaryl phosphine with the halogen compounds X-CH2-(CH2)n -CH2O acyl and X-CH2-(CH2)n-CH2-COO alkyl at an elevated temperature in the presence of a solvent such as benzene, toluene, xylene, or dimethylformamide, and examples describe the preparation of [9-carbomethoxynonyl]-triphenyl phosphonium iodide, [10-carbomethoxy - decyl] - triphenyl phosphonium iodide, and [10 - acetoxy - decyl - triphenyl phosphonium bromide.

Title: Improvements in or relating to machines for making glass bottles, jars and other hollow ware
IPC: C03B9/14
Filed: 1924-03-01
Abstract: 234,203. Cargo, W. F. March 1, 1924. Blowing.-A machine for making glass bottles, jars, and other hollow ware has two sets of reciprocating moulds, the parison moulds being alternately brought to the charging position and returned to the transfer position, and the finishing moulds alternately advanced to the transfer position and withdrawn to the blowing position. The parison moulds are secured to holders 8, 9 carried by drums 10, 11 each mounted on brackets on a carriage 15. An air cylinder 46 causes the movable carriage 15 to reciprocate between the charging position, which is in the centre of the machine, and a position at one end of the table 6. Each drum 10, 11 is provided with a spur wheel 12 which meshes with a, rack secured to the table 6. The reciprocations of the carriages 15 causes inversions of the parison moulds when travelling between their positions of rest. The parison moulds are opened and closed by air cylinders 18 mounted at the, ends of the table 6, and other cylinders 62 open and close the ring moulds. The finishing moulds are supported by carriages 25, 26 which slide along tracks 21, 24, respectively, at right angles to the table 6, and are reciprocated by air cylinders 28. Each mould is secured to holders 30, 31 carried by racks 32, 33 respectively, which slide in the carriages and are moved by air cylinders 34 to open or close the moulds. In operation, a parison mould is brought to the mid position and receives a. charge of metal through a funnel 44. The funnel is then swung to one side and a blow head 45 moves over the mould. The blow head delivers compressed air above the metal to compact it into the ring mould, and then serves as a mould cover when the parison is blown up to fill the mould. The mould is next moved to the end position of the table 6 and is turned over during the movement, the other parison mould being moved to the charging position at the same time. The first parison mould is then opened by the cylinder 18, and the finishing mould is moved inwards along the track 21 or 24 to receive the parison.

Filed: 1959-02-18
Abstract: 876,644. Toy road-vehicles and track; race games. TEMPEST, M. C. Feb. 12, 1960 [Feb. 18, 1959], No. 5584/59. Classes 132(2) and 132(3). A toy or model road vehicle is steered by means of current collected from a track, the extent of the steering being in correspondence with the potential applied and in lefthand or right-hand direction depending on the polarity. As shown, a toy or model vehicle is steered by an electromagnet 18, Fig. 2, and is driven by an electric motor 7 both receiving current from a track, the steering being controlled remotely by a steering wheel 44, Fig. 7, and the motor by a reversing handle 45 and a pedal accelerator. Individually controlled tracks, may be arranged side by side so that a corresponding number of vehicles can be raced one against another. The steering electromagnet 18 pivots a permanent magnet 14 to left or right to move a tracking bar 13 connecting the front wheel stub axles and the magnet 14, when not influenced by the electromagnet, is returned to a central position by permanent magnets 20. The magnet 14, instead of being pivoted at 15 separately from the tracking bar as shown in Fig. 2, may be secured to it. The motor drives the rear wheel axle 4 through a worm 6 and a worm wheel 5, The track comprises strips S and M, respectively supplying current for steering and for the motor, and also a raised strip C common to both. The strips S and M are contacted by conductive discs 8, Fig. 3, forming parts of the front wheels and the strip C is contacted by a trailing loopshaped weighted collector 21. Insulating feelers 25, Fig. 3, prevent the wheel discs 8 from touching the sides of the strip C, and if a vehicle is steered too far to one side of its track, it will be arrested when its feeler contacts an abutment adjacent the strip C, serving as a hazard. The track may be provided with side walls. The current supply to the track as shown in Fig. 6, the potentiometer 42 being controlled by the steering wheel 44, Fig. 7, the switch 40 by the reversing handle 45 and the sliding resistance 39 by the pedal accelerator (not shown). According to the Provisional Specification, the common conductor strip may be flush with the track surface or in the form of a groove and the permanent magnet which steers the wheels may be restored to its straight-ahead position by spring means.

Patent GB-420506-A (GB)
Title: Method of and means for obtaining inorganic acid gases from gaseous mixtures
IPC: C01B32/50
Filed: 1933-02-27
Abstract: <PICT:0420506/III/1> Inorganic acid gases, such as carbon dioxide, sulphur dioxide and sulphuretted hydrogen, are separated from gaseous mixtures by absorption in a substantially anhydrous undiluted difficulty volatilizable organic amine (other than a pure aromatic amine or a heterocyclic amine possessing similar properties), the acid gas being subsequently driven off with the aid of a vapour of an organic solvent which is insoluble in water and which forms with water an azeotropic heterogeneous vapour mixture.  Suitable amines include the amino-alcohols such as mono-, di-, or tri-ethanolamine, mono-propanolamine (aminoisopropyl alcohol) or phenylethanalamine, their homologues such as ethyl diethanolamine and the morpholine bases obtained from multiamine alcohols by dehydration, such as oxyethylmorpholine and its homologues.  The organic solvents referred to are benzol and its homologues, benzene, and halogenized hydrocarbons such as carbon tetrachloride and chloroform alone or in admixture; a mixture of benzol and carbon tetrachloride is particularly referred to.  The vapour of the organic solvent removes from the amine base any water it absorbs from the treated gases, in addition to the acidic gases.  A carbon dioxide containing gas enters an absorption tower 1 through a port 2 and passes up the tower in counter current to a stream of anhydrous amine alcohol, the carbon dioxide free gas passing away through a pipe 4.  The base, containing carbon dioxide, is pumped by a pump 7 through a preheater 8 into an extracting column 10 at a temperature of about 60 DEG  C.  The base descends the column in counter current to benzol vapour entering p through a pipe 12, is heated by a coil 15 to 140 DEG  C. to remove traces of benzol and is pumped by a pump 16 through the preheater 8 and a cooler 17 to re-enter the tower 1 via a pipe 3.  The benzol vapour containing carbon dioxide and water vapour passes through a pipe 13 to a cooler 14 which condenses the benzol and water.  This liquid mixture passes to a separator 18 while the pure carbon dioxide flows away through a pipe 22.  The layer of benzol passes from the separator through a pipe 20 to an evaporator 21 for the production of further benzol vapour for the tower 10.  The towers 1 and 10 may contain either column apparatus or coke or like fillings. Specification 344,786 is referred to.

IPC: A61K31/59
Filed: 1950-03-08
Abstract: A lipoid soluble, normally water-insoluble and substantially fat-free vitamin, e.g. vitamin A, D, E and K is solubilized by means of a water-soluble hydroxy-polyoxyethylene ether, containing 10 to 150 oxyethylene groups to the molecule, of a long chain aliphatic alcohol containing 12 to 22 carbon atoms to the molecule.  The hydroxy-polyoxyethylene ethers have a melting point of 40 DEG  to 100 DEG  C., and preferably 40 DEG  to 65 DEG  C., and typical examples are hydroxy-10 (15, 23, 45, 105, 150)-oxyethylene lauryl ethers, hydroxy-20-oxyethylene cetyl ether and hydroxy-20-oxyethylene stearyl ether.  The vitamin may be dissolved in the molten ether, if desired, in the presence of an inert atmosphere and the solution so formed may then be diluted with water in all proportions.  Generally 2 to 20 parts, and preferably 5 to 12 parts, of the ether are used for each part of the vitamin and the final composition contains 2 to 10, and preferably 3 to 8 parts of the ether per 100 parts of the finished solution.  The vitamin compositions when dissolved in water may be mixed with water-soluble vitamins, e.g. thiamine, riboflavin, pyridoxine, ascorbic acid, and nicotinic acid or its amide. Viscosity increasing materials, sweetening agents, flavouring agents and colouring agents may be added.  The compositions may be incorporated in human and animal foods.ALSO:A vitamin composition for incorporating in animal foods comprises a lipoid-soluble normally water-insoluble and substantially fat free vitamin e.g. A, D, E and K, or a vitamin-containing material, dissolved in a water-soluble hydroxy - polyoxyethylene ether containing 10 to 150 oxyethylene groups to the molecule and being a long chain aliphatic alcohol containing 12 to 22 carbon atoms to the molecule.  The polyoxyethylene ethers have a melting point of 40 to 100 DEG C, and preferably 40 to 65 DEG C, and typical examples are hydroxy -10 (-15 23, 45, 105, 150)-oxyethylene lauryl ethers, hydroxy-20-oxyethylene-cetyl and -stearyl ethers and hydroxy-23-oxyethylene oleyl ether.  Generally 2 to 20 parts, and preferably 5 to 12 parts, of the ether are used for each part of vitamin.  The vitamin may be dissolved in the molten ether, if desired in the presence of an inert atmosphere.  An example is given in which the solid produced from vitamin A and hydroxy-23-oxyethylene lauryl ether is incorporated in an animal food containing 90 per cent of a mixture of oil-expressed soyabean meal, alfalfa meal and oatmeal and 10 per cent of a mixture of calcium phosphate, potassium phosphate, sodium chloride and essential trace elements.
