Title: An improved manufacture of monocyclic hydrocarbons and their derivatives
IPC: C07C2/00
Filed: 1941-11-12
Abstract: 558,555. Cyclic hydrocarbons. STANDARD OIL DEVELOPMENT CO. Nov. 12, 1941, No. 14552. Convention date, Dec. 12, 1940. [Class 2 (iii)] Cyclohexane, benzene, and their alkyl derivatives are prepared by subjecting an aliphatic mono-olefin of 3 to 4 carbon atoms to the action of a volatile halide of the Friedel-Craft type (AlCl 3 , BF 3 , or HgCl 2 ) and a substantially non-volatile solid catalyst, comprising molybdenum sulphide and copper, at 20-350‹ C. In an example substantially anhydrous propylene is condensed to benzene and other hydrocarbons using boron fluoride and a molybdenum sulphide-copper mixture as catalyst. Other materials which may be added to the reaction mixture are acetylene, and carbonyls of chromium, molybdenum or nickel. Condensation reactions are avoided by rapid removal of the aromatics as formed followed by rapid hydrolysis of the halide catalyst. The Specification, as open to inspection under Sect. 91, includes the use, along with the volatile halide, of metal such as nickel or compounds of Mo, W, Al, V, U, Cr, Cu or Ni. Alkylation of the aromatic products by means of the olefin feed stock may be suppressed by the introduction of small amounts of sulphur or sulphur dioxide or other condensation inhibitor. This subject-matter does not appear in the Specification as accepted.

Title: Radiation detecting device
IPC: G01V5/06
Filed: 1954-05-24
Abstract: 786,194. Detecting radio-active radiation. MARTIN, P. W., and PRINGLE, R. W. May 24, 1954, No. 15191/54. Class 40 (3). A device for detecting radio-active radiation comprises a signalling means responsive to the radiation in one container, a cooling medium in another container and a member of high thermal conductivity interconnecting the containers, the walls of which are of low conductivity. Scintillations from a crystal 19, e.g. of transparent NaI activated with Thallium in response to radio-active radiation from the borehole wall produce pulses in photo-multiplier 20 which are lengthened at 23, amplified at 24, fed via a matching device 25 into cable 14 and hence to the surface. The pulses are then fed via commutator 27 and a matching device into amplifier 28 and are recorded by camera cathode-ray oscillograph 31 or fed through pulse discriminating network 29, the output of which is smoothed, to a recorder 30. Crystal 19 and photo-multiplier tube 20 which are in intimate contact are enclosed in a cap 49 (Fig. 2), filled with silicone oil for protection against moisture. Resilient pads 52, 53, e.g. of rubber are provided between them and the cap together with a sealing ring 59. The cap is fixed to the photo-multiplier base by a sleeve bolted to heat conducting tube 45 in which the photo-multiplier base is mounted, and to a ring 51 which engages shoulder 57 on the cap. Resilient pads 57<SP>1</SP>, 58 are also provided between the cap and vacuum bottle 41 in which it is mounted. The tube 45 extends out of the bottle and has a closed end 46 within a second vacuum bottle 18. A wire of good heat conduction extends from end 46 into a mass of ice contained within a cap 60 sealed and bolted to the tube and a resilient pad 64 is between the cap and bottle. The mouths of the bottles are sealed by annular cork member 42 on tube 45. The tube ensures temperature stability of the crystal and multiplier by providing good heat conduction between them and the melting ice. Tube 21 is a voltage stabilizer for the photo-multiplier supply. The bottles are packed in glass wool within a sleeve in exploration unit 16 which may also carry insulated electrodes for electrical logging and a power supply. The latter may alternatively be at the surface. For neutron logging of formations the unit 16 may contain a neutron source shielded from the crystal by #-ray shielding, e.g. Pb, Wo and alloys of heavy metals, and neutron shielding, e.g. Cd and organic materials. The source emits neutrons through a neutron beaming device consisting of a conical lead layer between absorbing layers into the formations adjacent the crystal where they produce #-rays by nuclear disintegration mainly of hydrogen atoms in hydrogenous materials. Masking of the variations of induced #-ray intensities corresponding to different formations by fluids in the borehole is obviated by a lead shield surrounding the unit 16 adjacent the source which displaces the fluid. Specification 732,893 is referred to.

Title: Vaccination method using temperature sensitive virus mutants
IPC: A61P31/22
Filed: 1973-03-30
Abstract: 1390467 Viral vaccines RECHERCHE ET INDUSTRIE THERAPEUTIQUES 30 March 1973 15307/73 Heading A5B Non-human animals are vaccinated against exanthematous viral diseases by the intradermal administration of a temperature-sensitive and substantially non-pathogenic mutant strain of the virus responsible for the disease. Such diseases include cowpox, smallpox, varicella, zoster, measles, rubella and Herpes Simplex infections. The invention is exemplified in particular with the last-mentioned infection. The expansion "temperature-sensitive" means that the virus has a cut-off temperature such that it is capable of multiplying in a "cold site" (i.e. at a site of an animal which is at a lower temperature than its internal organs) but will not multiply at sites within the body where the temperature is above the cut-off temperature.

Title: Improvements in apparatus for manufacturing glass in continuous strip form
IPC: C03B13/00
Filed: 1923-06-12
Abstract: 211,775. Hart, H., (Ford Motor Co.). June 12, 1923. Rolling.-Relates to the production of sheet glass in a continuous strip, as described in Specification 196,293, and consists of a device for keeping the width of the strip constant. The glass issues from the spout of a tank on to an endless travelling table 1 and is carried by it beneath a roller, the edges of the pool of glass on the table and of the strip 2 being unconfined, the width of the strip being determined by the speed of the table and the rate of feed of the glass. The device consists of a frame 4 which is free to move transversely to the strip on wheels 5, and two rollers 7, 9, which make contact with the edges of the strip 2. The roller 7 is fixed relatively to the frame 4, although its position can be adjusted, but the roller 9 is carried on one arm 10 of a lever that is pivoted to the frame, the other arm 12 being loaded by a counterweight 13 or a spring. The arm 12 carries a movable contact 14 which can make contact with either of two fixed contacts 15, 16 of an electrical circuit controlling the feed or the speed of rolling. In operation, the device as a whole is free to accommodate itself to the position of the strip 2 on the table 1, but any variation in the width of the strip causes the roller 10 to move the contact 14 and thus vary the factors controlling the width. In place of the electrical contacts, the arm 12 may operate a valve in a hydraulic or pneumatic relay system.

Title: Process for the manufacture of dyestuffs of the triarylmethane series
IPC: C09B11/20
Filed: 1933-05-29
Abstract: Triarylmethane dyestuffs containing the grouping >N-alkyl SO3H are prepared by treating triarylmethane dyestuffs, triarylmethanes or intermediates therefor which contain the grouping >N-- alkyl OSO3H with alkali sulphites at elevated temperature, and in the case of the triarylmethanes and the intermediates transforming the products into the dyestuffs according to known methods.  When more than one sulphuric ester grouping is present, by treating with an insufficient quantity of alkali sulphite to transform all the said groups, and saponifying the products, dyestuffs containing hydroxyalkyl groups as well as sulphoalkyl groups are obtained.  In examples: (1) di-[2-chlor-4-(N-hydroxyethyl-n-butylamino) phenyl] - 1 - methane, obtained from formaldehyde and m-chlor-N-hydroxyethyl-n-butylaniline, is treated with sulphuric acid, and after neutralization is heated with sodium sulphite; the resulting diarylmethane is oxidized to form the carbinol, condensed with diethylaniline and converted to the corresponding dyestuff; (2) tri-[2-methyl-4-(N-butyl-hydroxyethylamino) phenyl]-1-methane, obtained by condensing the diarylmethane from formaldehyde and N-butyl-hydroxyethyl-m-toluidine with N - butyl - hydroxyethyl - m - toluidine after oxidation to the hydrol, is similarly transformed first to the sulphuric ester and then to the sulphoalkyl derivative, which is oxidized to the dyestuff; (3) the sodium salt of the sulphuric ester of the leuco base obtained from o - chlorbenzaldehyde and N - hydroxy - propyl-n-butylaniline is heated with sodium sulphite and the resulting leuco compound oxidized to the dyestuff; (4) the sulphuric ester of the dyestuff obtained from benzaldehyde and N-butylhydroxyethylaniline by condensation and oxidation is treated with sodium sulphite; by oxidizing the resulting leuco compound and salting out, the dyestuff is separated: (5) the hydrol obtained by oxidizing the diarylmethane from formaldehyde and N-butylhydroxyethylaniline is condensed with N-butylhydroxyethylaniline and the leuco compound transformed to the dyestuff; after sulphonation, the sulphuric ester is treated with sodium sulphite as in the previous examples.  N-Hydroxypropyl n-butylaniline, required in example 3 is prepared by acting with propylene oxide upon n-butylaniline.
