Title: Method for the separation of plutonium from uranium
Inventor: HAEFFNER ERIK AXEL
IPC: C22B60/02
Filed: 1958-03-07
Abstract: 841,602. Separation of plutonium. ATOMENERGI A. B. March 7, 1958, No. 7409/58. Drawings to Specification. Class 39(4). Plutonium is separated from an organic solution containing uranium and plutonium by passing the solution through a solid having adsorbed thereon a liquid immiscible with the organic solvent, which liquid dissolves plutonium in preference to uranium. An organic solution obtained by extraction of a nitrate solution of irradiated uranium is passed through a column of solid which has been treated with dilute nitric acid. Uranium passes through the column and any remaining may be washed out with base organic solvent. Plutonium is removed from the column with organic solvent containing nitric acid or with an aqueous nitric acid solution. The preferred adsorbent is silica gel, but reference is also made to diatomaceous earth, fuller's earth, bentonite, and paper and cellulose products. Tributyl phosphate and the dibutyl ether of diethylene glycol are referred to as organic solvents and a number of others are mentioned. The solvent may be diluted with a hydrocarbon fraction or carbon tetrachloride. The process also effects a separation of plutonium from fission products.

Title: Process for reducing the feltability of wool
Inventor: PADGETT ERIC MCKINNEL
IPC: D06M11/09
Filed: 1948-03-15
Abstract: The feltability of wool fibres is reduced by treating material composed of or containing the fibres with gaseous chlorine, the material being progressively passed through a chamber, chlorine gas being continuously fed into the chamber, and water vapour being withdrawn from the chamber as and when necessary, the rate of passage of the material and the rate of feed of the gas being controlled so that each fibre is exposed in the chamber to the amount of chlorine which is required having regard to the particular nature of the material including its weight and its moisture content.  In the example a woven wool fabric containing 25 per cent total moisture is passed in open width piece form through a chamber of 1200 cubic feet capacity at a rate of 189 oz. per minute.  The fabric enters the chamber through a horizontal slot near the top of one wall of the chamber and passes over rollers in the chamber so that loops of the fabric extend down towards the bottom of the chamber.  At the end of its passage through the chamber the fabric emerges through another horizontal slot near the top of the same wall of the chamber.  The length of the path of the fabric in the chamber is such that each portion of the fabric is in the chamber 3.75 minutes.  Chlorine gas is introduced at the rate of 3.20 oz. per minute into the bottom of the chamber where it forms a "pool" into which the loops of fabric dip.  Water vapour is removed from the top of the chamber by means of a light exhaust fan, and the rate of feed of fresh chlorine into the chamber is so controlled with respect to its consumption that the "pool" of chlorine does not rise to the top of the chamber and little, if any, unreacted chlorine is exhausted from the chamber by the fan.  The chamber is at room temperature and atmospheric pressure.  Data are given for the potential felting shrinkage of the fabric before and after treatment and similar data are furnished for other fabrics together with the conditions under which they were treated.  Specification 417,719 is referred to.

Title: Improvements in breech loading rifles, shot-guns and like small arms
IPC: F41A17/76
Filed: 1929-03-11
Abstract: 330,599. Gardiner, R. M. March 11, 1929. Breech actions, sliding-breech block; firing-appliances. - The firing mechanism comprises a spring-pressed plunger engaging with a pivoted hammer and mounted in a carrier which may be moved so that the plunger acts alternately above or below the pivot of the hammer. The hammer 11 is pivoted at 11<a> and is actuated by a roller 15 mounted on a spring-pressed plunger 12 in a carrier 14. The carrier 14 is pivoted at 14a and is rocked on its pivot by a roller 16<1> which engages with a curved surface on the carrier. The roller 16<1> is mounted on a lever 16 which is moved by a hand-slide on the firearm through the medium of a rod 17. Rearward movement of this rod depresses the carrier and moves the roller 15 below the pivot 11<a> of the hammer 11 which, when released, strikes the firing pin 13. The surface of the hammer on which the roller 15 engages is so shaped that the roller automatically returns to the " safe " side of the pivot 11<a> when the hand-slide is returned to its forward position. The pivoting of the carrier below the axis of the plunger also helps the return movement of the carrier to its " safe " position. The hammer is held in its cocked position by the trigger-sear 18. Safety-mechanism is provided to prevent discharge when the breech-bolt is unlocked. This mechanism comprises a latch 20, pivoted at 20<a>, having a lip 24 which engages with a lip 23 of the hammer when the breechbolt is unlocked. In this position also, the trigger, which engages with a spring-actuated pin 19 within the latch, is prevented from moving by the engagement of the upper end of the pin with the breech-bolt. A lug 28 of the breech-bolt engages with a lug 26 of the latch when the breechbolt is locked, and rotates the latch about its pivot. This movement disengages the lips 23, 24 and brings the upper end of the pin 19 opposite a hole 22 in the breech-bolt and the gun may then be fired. The barrel is secured in the breech frame by a tapered spigot-and-socket connection and a transverse cotter pin.

Abstract: 1482323 Spectrofluorometer BAXTER TRAVENOL LABORATORIES Inc 25 Feb 1975 [20 March 1974] 7907/75 Heading G1A A spectrofluorometer comprises a source 20, a chopper 22 defining a first optical channel to transparent sample cell 17 and a second channel as beam 23; means including chopper 22 defining a second channel between the sample and a photocell 11, reference source 31 and means including chopper 22 to define a channel therefrom to photocell 11, time spaced with the second channel and means 14 controlling the response of photo-cell 11 in accordance with the energy content of beam 23 and the signal generated in photo-cell 11 by reference source 31. The embodiment of Fig. 1 is for a fluorescent sample. Beam 18 is time spaced with beam 23. Switch 36 is synchronized with chopper 22 to connect alternately measure and reference signal channel 37 and 38 respectively to photo-cell 11 mono-chromator 19 emits beam 21 of a selected wavelength or several wavelengths in time sequence. Cell 25 is of half the path length of cell 17 and contains material of the same absorbancy. Detector 26, whose surface charge difference varies with temperature, supplies an energy correction signal. Mono-chromator 29 selects an emission wavelength. Reference source 31 may supply light of 660 nm. Disc (22), Fig. 2 (not shown) has diametrically opposed notches (40), which simultaneously expose detector 26 to beam 21, and light pipe 33 to source 31. Opposed mirror spaces (42) are between two pairs of light absorbing spaces (41) adjacent notches (40) and simultaneously reflect beams 18 and 27. The measure signal is processed in current to voltage amplifier 43 and base line correction amplifier 44, coupled to mono-chromator 29 and dividing the signal by a term dependent on wavelength dependent factors for the omission optical path and photomultiplier 11. Conversion device 45 gives a change α wavelength or (wavelength) <SP>3</SP> to give a signal as the number of quanta per nm bandwidth or per cm<SP>- </SP><SP>1</SP>. Device 46 subtracts the signal produced by dark space (41). 48 is a current to voltage amplifier and device 49 changes the gain in proportion to the wavelength of mono-chromator 19. Device 50 subtracts a dark space signal. Device 51 subtracts the reciprocal of the energy correction signal, and the resulting signal controls the high voltage supply 14 hence the gain of photo-multiplier 11. The instrument may be modified to measure absorbance by placing a plane mirror beyond cell 17.
