Title: Improvements in or relating to neutron flux plotting systems
Inventor: GRAY ALAN LYLE
IPC: H01J47/12
Filed: 1959-06-19
Abstract: 956,555. Ionisation chambers. PLESSEY CO. Ltd. Aug. 8, 1960 [June 19, 1959], No. 21175/59. Heading H1D. [Also in Division G6] An ionisation-type reaction detector comprises the electrodes 1, 2 of which the anode 1 has a coating 15 which emits particles, during neutron bombardment, which ionise the gas between 1 and 2. To maintain the sensitivity of the device constant, the burn-up of 15 is compensated by the increase in neutron transmission through the coatings 16, 17, 18 as the latter are burnt away by the neutron flux and thus absorb fewer neutrons. Boron 10 or uranum 235 may be used for layer 15. A pumping stem 12 is provided for evacuating the casing 4, and subsequently refilling with a gas.

Abstract: 694,370. Silencing gaseous currents. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. Aug. 28th, 1950 [Sept. 2, 1949], No. 21210/50 Class 7 (ii). In a device for silencing sound in a gaseous medium comprising a plurality of chambers having mainly parallel sides and closed at one end, such as tubes 2, and in direct communication with an annular channel of flow for the gaseous medium surrounding the tubes 2, and the longitudinal axes of the tubes being parallel to the longitudinal axis of the channel, the lengths of the tubes are so adapted that the natural frequencies of oscillation of the tubes coincide wholly or partially with the frequencies of the oscillating gaseous medium. A circular plate 1 has a flange 3 by which it is secured to a conical casing 7, whilst the.nested tubes 2 extend from the plate 1 into the casing 7, the tube of smallest diameter having the greatest axial length; the channels formed between the tubes 2 are of equal cross-section. The apparatus can be used as an intake or exhaust silencer, the air or other gaseous medium entering or leaving the silencer through an annular opening 9 between the flange 3 and the casing 7 and flow through the annular space between the casing and the tubes 2, which latter space is about twice the cross-section of the channels between the tubes and is of approximately constant area throughout its length. In a modification, the conical casing is perforated and surrounded by porous sound-absorbing material, such as asbestos or glass wool. In a further modification, the silencers of the kind illustrated in Fig. 1, are arranged back-to-back upon a common circular plate, the two conical casing parts being separated by a cylindrical portion. In another modification, a bi-conical casing covered with sound absorbing material houses a conical plate to which the tubes are secured. The radial depth of the annular space from any open end of a tube is small compared to the length of the tube; the free ends of the latter may be streamlined. The tubes may form a series having lengths of 1, ¢, 1/3, “, and so on where 1 corresponds to “ of the wave length of the fundamental tone in the medium to be damped. Parallel pipes or. cells may replace the nested tubes and the plate upon which the tubes are mounted may be carried by the surrounding housing through the intermediary of sound-insulating members.

Title: Improvements in or relating to anion-exchange resins
IPC: C08F8/44
Filed: 1953-07-31
Abstract: Water-insoluble polymers of aryl acetylene hydrocarbons containing a plurality of groups of the formula -A-NR3OH, in which A is an alkylene group and R is an alkyl or aralkyl group, are used as anion-exchange resins.  The polymers may be homopolymers of aryl acetylenes or copolymers of one or more aryl acetylenes and another monomer.  In the case of copolymers the groups may be attached to either the acetylenic or the other monomer unit.  The polymers may be made by (1) polymerizing aryl acetylenes containing aminoalkyl or quaternary ammonium alkyl groups and subsequently converting these groups to the quaternary ammonium bases by exhaustive alkylation treatment with sodium hydroxide; (2) copolymerizing monomers, e.g. vinyl aromatics, containing aminoalkyl or quaternary ammonium alkyl groups with aryl acetylenes and after-treating the copolymers to convert the groups present in the copolymers to quaternary ammonium bases; (3) chloromethylating aryl acetylene polymers, reacting the products with ammonia or an amine and forming the quaternary ammonium hydroxide groups by exhaustive alkylation and treatment with sodium hydroxide; or (4) reducing the cyano groups in polymeric aryl acetylenes containing such groups and converting the amine groups to the quaternary ammonium groups by exhaustive methylation and sodium hydroxide treatment.  The polymers may be mixed with inert material such as diatomaceous earth, alundum, coke, silica, cinders, or porous glass at any time prior to complete conversion of the polymer to the water-insoluble stage. The acetylenic polymers may be formed by polymerization of the monomers in bulk, solution, or aqueous emulsion or suspension preferably in the presence of a catalyst such as benzoyl, hydrogen, acetyl, acetyl-benzoyl, phthalyl, or lauroyl peroxide, t-butylhydroperoxide, ammonium persulphate, sodium persulphate or sodium perchlorate, or Friedel-Craft catalysts such as aluminium chloride.  Acetylene and substituted acetylene monomers mentioned are phenyl acetylene, tolyl acetylene, xylyl acetylene, naphthyl acetylene and para-phenyl-phenyl acetylene.  The other monomer may be styrene, o-, m-, or p-methyl styrene, dimethyl-styrenes, o-, m- or p-ethyl styrene, isopropyl styrenes, tolyl styrenes, benzyl styrenes, cyclohexyl-styrenes, methoxy-styrenes, phenoxy-styrenes, o-, m- or p-chlorostyrenes, o-, m- or p-fluorostyrenes, chloromethyl-styrenes, fluoromethyl-styrenes, trifluoro - methyl - styrenes, vinyl naphthalene, vinyl - methylnaphthalenes, vinyl - ethylnaphthalenes, vinyl - chloro - naphthalenes, vinyl - methyl - chloro - naphthalenes, vinyl diphenyl or vinyl fluorene.  In an example, a copolymer of phenyl acetylene and styrene in bead form is obtained by polymerizing phenyl acetylene and styrene containing dissolved benzoyl peroxide and t-butyl perbenzoate, in an aqueous medium containing hydroxy apatite and sodium oleate.

Title: Improvements in and relating to machines for slicing loaves of bread and like articles
IPC: B26D1/25
Filed: 1934-07-20
Abstract: 429,713. Slicing-machines. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. July 20, 1934, No. 21317. Convention date, Feb. 27. [Class 28 (ii)] A slicing-machine, particularly for loaves, comprises a rotary conical helical knife 112, a conveyer system 18, 19 with pusher plates 16 and clamp plates 17 between which loaves are held and fed along a table 12 towards and past the knife and along guides for the sliced loaf to the ejecting-plate 155. The loaves are fed to the table 12 over a shoot 10, and, until the loaves are received between the plates 16, 17, the loaves are moved over the table by an upper conveyer having pusher plates 79 which are pivotally attached to the conveyer chains and have roller ends 77 engaging with cam tracks for raising or lowering the plates, relatively to the chains, at the appropriate positions. The loaves on the table 12 are supported at the sides by guide bars 95, an adjustable side plate 21 and a spring-influenced adjustable plate 86 aligned with the plate 21. Adjacent to the cutting position, a pivoted weighted presser 99 bears on the top of the loaf, and one side is pressed by the plate 86 against a plate 103 having downwardly inclined grooves which tend to press the loaf firmly on the table 12. The plates 16, 17 pass along, a longitudinal slot between the table 12 and an auxiliary support, and are mounted on carriages having rollers which run in guide slots which keep the plates upright relatively to the conveyer 18, 19. At the cutting position, the loaf is supported, against the pressure of the knife, by a rotating cage-like member having upstanding bars 109, the knife working in the spaces between the bars. The sliced loaf is moved along adjustable guide members by the plates 16, 17 until it is engaged by the ejector 155 which has spring controlled pivoted ends 156 which yield if the plate 16 or 17 is fouled. The ejector 155 is carried on a shaft 149 rotated by a sprocket 148 to which it is slidably feathered. A roller 151 on a member secured to the shaft 149 works in a cam-groove 152 inside a stationary sleeve 153, so that the ejector follows the longitudinal movement of the loaf during its ejecting period. The motor is connected to the knife shaft 27 by a belt drive 25. The height of the shaft 27 is regulable by a screw-adjustment 166, 167, whilst the motor is slidably mounted for screw adjustment of the belt tension. The knife 112 comprises a spiral edged plate, having a radial slit between the leading and trailing edges, which is clamped to a helical backing plate 110 by a clamping-ring which is similarly split and distorted. To alter the slice-thickness, a knife assembly and cage 109 of different pitch are used, and the conveyer speed is altered correspondingly by a changespeed gear controlled by a lever 186. Specification. 419,615 is referred to.

Title: Improvements relating to electrode supporting means for electric furnaces
IPC: H05B7/107
Filed: 1951-09-11
Abstract: 700,218. Furnace electrode mounting. ELECTROKEMISK AKTIESELSKAP. Sept. 11, 1951 [Sept. 13,1950], No. 21375/51. Class 39 (3). A Soderburg or pre-heated vertical electrode 1 of a furnace to be occasionally lowered is gripped and supported by a main electrode clamp 3 which when loosened by remote control allows the electrode to slide, and a collar 3<SP>1</SP> clamped to the electrode moves down with it until the collar engages a fixed stop and so prevents further downward movement. The remote control for the tightening or loosening of the clamp 3 and collar 3<SP>1</SP> comprises a hydraulic or pneumatic system. The collar 3<SP>1</SP> carries compression springs 9 bearing on buffers 10 in the collar. The buffers engage the fixed stop, which comprises a part of the furnace or members 11 on the main clamp 3. The collar 3<SP>1</SP> and clamp 3 may be water-cooled and have movable arms 4 pivoted at 5 and embracing the electrodes, the outer ends of the arms 4 carrying co-operating parts of a cylinder 6 and piston 8. A compression spring 7 in the cylinder bears on the piston 8 so as to hold the electrode. When the electrode is to be lowered. compressed air or liquid is admitted by a pipe 12 under the remote control to force the piston against the spring and thus release the pressure of the clamp on the electrode. After the downward movement. the air pressure on the piston is released, whereby the clamp again grips the electrode. The collar 3 is then released by air pressure'on its piston. whereupon the springs raise the collar to its original position and on release of the air pressure, the collar again clamps the electrode ready for the next lowering. preferably from 2 to 10 cms. A valve supplies compressed air to only one cylinder at any one time, so that the electrode is always gripped ; but for removal of the electrode, air is supplied to both pistons simultaneously. Current is normally supplied only to the main clamp. but it may also be supplied to the collar which may be mounted below the clamp on bars projecting downwardly therefrom, said bars having enlarged heads and carrying buffer springs. Other types of clamps, e.g. those in which pressure pads are surrounded by a pressure ring may be used. The collar may be mounted on the upper part of the electrode casing 2 or its ribs.
