A radiation detector comprises an enclosure containing an electrode, insulated therefrom, and helium-3 gas under superatmospheric pressure, preferably 10-20 atmospheres, whereby thermal and epithermal neutrons impinging on the gas may be detected upon establishment of an electrostatic field between the electrode and the enclosure. The detector is highly sensitive to low energy neutrons at operating voltages of between 1500 and 2000 volts while being insensitive to gamma rays. As shown, a wire electrode 13 is supported by quartz or ceramic rings 16 in an aluminium enclosure 10. Electrodes 23, 24 are provided to minimize end effects. In order to detect only epithermal neutrons, the counter may be surrounded by a cadmium or boron shield 50 which absorbs thermal neutrons and transmits epithermal neutrons. In a method of well-logging, the counter, supported in a fluid-tight container, is used to measure the natural neutron activity of the earth formations or neutron radiations induced therein by a neutron source provided in the container. Prior art counters employing boron trifluoride gas are referred to.

Title: Improvements in or relating to fluid pressure control devices
IPC: B67C3/22
Filed: 1957-08-02
Abstract: 866,911. Valves. FARRINGDON WORKS & N. PONTIFEX & SONS Ltd., and HAMILTON, J. G. Aug. 1, 1958 [Aug. 2, 1957], No. 24595/57. Class 135. A fluid-pressure control device comprises a chamber adapted to receive a first fluid, an inner chamber disposed within the first chamber and adapted to receive a second fluid, the inner chamber comprising an axially compressible and extensible tubular element operatively associated with valve means for controlling the passage of the second fluid into the inner chamber, the tubular element operating the valve means in response to pressure variations in the first and/or second fluid to maintain a required differential pressure between the fluids in the two chambers. The invention is described as applied to counter-pressure bottling apparatus, the valve operating to maintain a constant differential pressure between the bottled liquid and the counter-pressure air or gas with which the bottles are initially charged. As shown, the control valve consists of a piston 11 working in a cylinder 10 and connected by a rod 12 to a weighted member 13 sealed to the upper end of a bellows element 17. The lower end of the latter is sealed to the base of a reservoir 2 which receives the liquid through an inlet pipe 3 and discharges it through an outlet pipe 7 to the filling head chamber 6. The interior of the bellows 17 is subjected to the counter-pressure of air or other gas in chamber 5, through a pipe 26 and a cylinder wall port 25. When the apparatus is working normally with a predetermined pressure differential between the outside and inside of the bellows 17 the piston valve 11 closes inlet and outlet ports 24, 30 in the cylinder wall; should the differential exceed this value contraction of the bellows results in valve 11 opening port 24 for the admission to the interior of the bellows of gas under pressure from an inlet pipe 23 and port 22, but should it fall below this value expansion of bellows 17 allows valve 11 to open outlet port 30 to vent the interior of the bellows to the gas return chamber 8 through outlet port 29 and pipe 28. The desired operating pressure differential may be varied by adjusting, by means of a hand wheel 36, the force exerted by a loading spring 31 connected to the valve 11.

Abstract: 788,333. Masking tape applying machines, MINNESOTA MINING & MANUFACTURING CO. Aug. 26, 1955 [Aug. 26, 1954], No. 24655/55. Class 73 Relates to a machine for applying adhesive tape to one or more edges of a sheet of paper used for masking purposes in painting operations, the tape being applied to overlap the edges of the paper., so that it can be made to adhere to the surface being painted. According to the invention the supply roll 10 for the paper and the supply roll 15 for the tape are so mounted that the wrap of the tape around a combining roller 20 is less than that of the paper. In the form shown the drum 10 has a brake 41 whereby the paper 11 is put under tension, and the drum is so disposed that the paper will extend through 180 degrees around the roller 20. A bar 40 supports the length of paper passing to the roller. The roll 15 is arranged so that the tape 16 will engage and overlap one edge of the paper, and so that its wrap around the roller 20 will be about 9 degrees. The combined web 31 is drawn off by hand, being supported by a roller 25 and severed by a knife 32. The two rollers may be made in sections so that neither the tape nor the paper will have a propulsion effect upon the other. As shown in the Figures a single machine may incorporate more than one set of supply rolls and associated mechanisms. If non-tacky tape is used a moistening or heating means is disposed between the roller 20 and roll 15, and the roll 15 is fitted with braking means and is placed in a lower position..

Title: Process for the preparation of para-di-isopropyl benzene and terephthalic acid
Inventor: MAX NICOLAAS
IPC: C07C51/265
Filed: 1953-09-09
Abstract: A continuous process for preparing p-di-isopropyl benzene comprises alkylating benzene or cumene to form an alkylation product containing o-, m- and p-, di-isopropyl benzenes, separating the p-di-isopropyl benzene and a fraction containing o- and m-di-isopropyl benzene and subjecting the fraction to an isomerization treatment and removing p-di-isopropyl benzene from the isomerized product.  The resulting p-di-isopropyl benzene may be dissolved in 5 times its weight of propionic acid containing as catalysts manganese acetate and cobalt acetate and oxygen passed through at atmospheric pressure and at a temperature of 135-137 DEG  C.  Methanol, formaldehyde and formic acid distil off and terephthalic acid of 99 per cent purity was obtained by washing with acetone and drying the precipitate which was removed from the mixture after 22 hours.  In the alkylation step, the catalyst may be sulphuric acid, aluminium chloride, boron fluoride, hydrofluoric acid, aluminium silicate, alumina impregnated with hydrofluoric acid, phosphoric acid and titanium tetrachloride. The catalyst used in the isomerization stage may be aluminium chloride or boron fluoride.  In a typical example of the isomerisation step a fraction containing 3 per cent para-, 33 per cent ortho-, and 64 per cent meta-, diisopropyl benzene was heated at 65 DEG  C. with anhydrous aluminium chloride.  The product, after removal of cumene and tri-isopropyl benzene was substantially free from o-di-isopropyl benzene and contained 32 per cent of the p-isomer and 68 per cent of the m-isomer.  Specifications 737,439, 749,186 and 749,187 are referred to.
