Title: Preparation of halopyridines
Inventor: TITTLE BARRY
IPC: C07D213/61
Filed: 1965-01-19
Abstract: Highly fluorinated halopyridines of the formula C5FnCl5- nN where n is an integer from 3 to 5 are obtained by contacting at atmo spheric pressure less highly fluorinated fluoro chloropyridines, containing at least two fluorine atoms per molecule, with a melt containing potassium or caesium fluoride at a temperature above 700 DEG  C.  The reaction may be carried out using a melt which also contains potassium chloride, e.g. the potassium fluoride/potassium chloride eutectic mixture containing 45 moles per cent KF and 55 moles per cent KCl, and by passing the reactant fluorochloropyridine in a stream of an inert carrier gas, e.g. dry nitrogen, preheated to about 300 DEG  C. through a platinum tube into the bottom of the melt and so that the contact time between the reactants is about one second. Examples are given in which the starting materials are (a) trifluorodichloro pyridine and (b) mixtures of trifluorodichloro pyridine and difluorotrichloropyridine.  Reference has been directed by the Comptroller to Specification 914,933.

Title: Process for the production of valuable oxidation products from aliphatic hydrocarbons
IPC: C07C51/00
Filed: 1937-01-26
Abstract: <PICT:0489443/IV/1> Higher aliphatic hydrocarbons, such as solid and liquid paraffins and higher hydrocarbons from the benzine syntheses are oxidized by oxygen or oxidizing agents such as ozone or nitrogen oxides, with or without the use of catalysts, and fresh material is continuously supplied, a part of the oxidized product is continuously saponified, the unsaponified matter is continuously separated by centrifuging, and is returned to the oxidation process.  As oxidation catalysts there may be used manganese, cobalt, copper, iron, chromium, lead, or vanadium or their salts, or aluminium salts with or without alkalies, alkaline earths or their salts.  The metals may be in the form of soaps of saturated or unsaturated fatty acids, naphthenic acids or resinic acids. The oxidation temperature may be 90-200 DEG  C.  Catalysts may be omitted if some previously oxidized material is present.  The separated soap may be freed from remaining unsaponifiable material by treating with solvents such as acetone, or ethyl acetate.  In the apparatus shown, the hydrocarbon material is heated in a vessel A and further heated to reaction temperature in a pipe C leading to the reaction vessel D, air being injected by a pipe E.  The liquid is circulated by a vane rotor F.  The reaction product is passed through saponification vessels L1, L2, L3 having stirrers M1, M2, M3, to a centrifugal separator O from which unsaponifiable material is returned to the reaction vessel.  In an example, a semi-solid hydrocarbon synthetic paraffin mixture is oxidized at 105-115 DEG  C. by air in the presence of manganese palmitate, and the separated soap is dried and extracted with acetone.  Reference has been directed by the Comptroller to British Specifications 303,560, 324,189, [both in Class 2 (iii)], and 434,311, and U.S.A. Specification 1,987,208.

Abstract: 1,005,518. Newspaper vending machines. NEWSPAPER ENTERPRISE ASSOCIATION Inc. Jan. 20, 1964 [Jan. 28, 1963], No. 2351/64. Heading G4V. A vending machine for dispensing articles, such as newspapers and magazines, one at a time towards a discharge passage 13, Figs. 1 and 10, comprises a pusher 40, Fig. 3, which urges a stack of articles N against retaining means 60, means 85 operated as by a handle 11 for elevating the leading article to clear the retaining means for release and a guide 63 which is urged as by a spring 66 against the stack of articles and serves to prevent the released article from striking the retaining means. The pusher 40 is arranged to constantly push the stack along horizontal supporting bars 35 towards the retaining means 60 by a spring 57 which is secured at one end to a selected position in a bracket 58 and at the other to a rod which is bent into lengths 51, 52, 55, pivots in a bearing 53 and engages a slot 43a of a pusher plate 41. Upon insertion of coinage into a slot 8, the handle 11 is freed for rotating, through bevel gears 73, 76, a shaft 75 which carries at each end a plate 77 and a pivotable arm 77 for carrying the means, which is in the form of a bar 85, for elevating the leading article; depression of the handle causes the bar to move clear of both the retaining means 60 and the guide 63, from the position shown in Fig. 3 to that shown in Fig. 10. The bar is provided with adjustablymounted pins 105 and rubber lips 104, the lowermost lip being of such length that it serves to free the pin from the article upon reaching the position shown in Fig. 10 whereupon the article can then slide down under its own weight on to a platform 29 in the discharge passage 13; a recess 30 in the front panel 3 allows the customer to grasp the article. The bar is pressed against the leading article by a spring tape and reel 90, 91 provided at each end and a guide 150 is also provided for deflecting the bar towards the article upon the event of sudden operation of the handle. Fig. 21 shows an alternative form of bar 160, folded metal or plastic strips 169 being provided instead of rubber lips; upon the machine being operated when empty, the pins are arranged to enter corresponding holes in the pusher plate 41 and be locked therein by the folded strips. The front panel 3 can be lifted clear of the machine when a door 6 is opened thereby allowing the framework which carries the dispensing mechanism to slide into and out of the housing 2 and be secured therein by a single bolt 127.

The semicylindrical members divide a housing into inlet and outlet chambers, a diverter 23 being located in the outlet chamber 32 adjacent the active region to effect uniform distribution and pressure of the flowing liquid. Each chamber ineludes a respective manifold 18, 19 formed with ducts 71 through which the liquid is introduced into the inlet chamber and extracted from the outlet chamber. The manifold 19 may augment the diverter in obtaining uniform liquid distribution in the active region. The flash tubes 55, 56, Figs. 1 and 2, are mounted in removable support members 57, 58 by clips 68, 69, and are backed by U-shaped reflectors 63, 64 forming a duct for a circulated coolant such as water. Outlet and inlet pipes 67 and 73 are provided for the coolant, the latter being insulated from the housing and providing a high voltage electrical connection to the flash tube clips 69. A heat insulating material 65 fills the spaces between the support members and the semicylindrical members, and electrical insulating plates 59, 60 shroud the outer surfaces of the support members. Seals such as 35, 36, 45 and 46 are provided between the various structural components, and windows 25, 26 for the laser radiation are fitted to the housing end walls. External resonator mirrors 83, 84 are used, Fig. 3, adjustable tuning of the laser radiation being effected by angular adjustment of mirror 64 relative to a fixed chain 82 of dispersion prisms.

Manual exchange systems. -The degree of amplification provided by an amplifier incorporated in a cord circuit is adjusted automatically in accordance with the requirements of the two lines connected together at any time. As shown, the lines are arranged in four grades, and the completion of a connection results in the operation of two of the position relays 32 - - 35, or only one if the lines are of the same grade, to effect a combined gain setting by means of the relays 40 - - 43. For example, the gain setting may be determined by the value ¢(a + b), when a, b are figures representing the line gradings, a fraction being neglected. The usual manual gain control may be retained and may be arranged to supersede the automatic control. To connect two lines 1, 2, plugs 12 - - 15 are inserted, the additional pair connecting up balancing networks 3, 4, and key 16 is thrown to close the filament circuit of the amplifier 5.

Direct liquid-pressure apparatus.-Apparatus for storing oil and delivering it by means of pressure water comprises a tank 1 for the oil connected by a pipe 3 to one or more discharge nozzles at different levels, and by pipes 4, 5 to a water supply 6. The oil passes from the pipe 3 through a pipe 13, meter 14, and valve 24 to a hose 15, which is normally supported on a hook 40 on the meter panel. The water pipe 5 has a valve 18 which automatically closes when the apparatus is not working, and is opened by a solenoid 20 when a switch 23 is closed by the removal of the hose from its hook. The hook is mounted on a pin 44 pivoted in a sleeve 39 fixed to the panel and! is turned upwards slightly by a spring 45 when the hose is removed. This movement disengages' a latch 51 from a latch 36 on an arm 34 fixed to a spindle 29 which may be turned by depressing an arm 33 to open the spring-pressed valve 24.
