Title: Method of and means for detecting variations in wall thickness of metal tubes
Inventor: NOLTINGK BERNARD EDWARD
IPC: G01B7/312
Filed: 1957-06-06
Abstract: 836,635. Electric tests. T.I. (GROUP SERVICES) Ltd. Sept. 2, 1958 [June 6, 1957], No. 18017/57. Class 37. The eccentricity of the bore of a tube 1 is determined by coils inside the tube generating fields which are detected by diametricallyopposite coils outside. As shown, coils A, A 1 , mounted on a support 3, enter the bore of the tube and are spaced from its walls by pins 6. Aligned with the coils A, A<SP>1</SP> are external coils B, B 1 , the spacing of which relative to the outside of the tube is determined by pins 5. Each coil B, B 1  is in two parts, B 1 , B2 and B  1 <SP>1</SP>, B 2 <SP>1</SP> respectively. The parts are so designed that the change in voltage in each part is the same if the coil moves away from coil A, although the absolute valve of these voltages differ. Thus, the effect of variation in the distance between coils A and B cancels out. The connections are shown in Fig. 3. Oscillator O feeds tuned coils A, A 1  and phasesensitive detector D. The two parts of each of coils B, B 1  (i.e. B 1 , B 2  and B 1 <SP>1</SP>, B 2 <SP>1</SP>) are mounted in opposition as are the coils themselves. The difference of output representing the eccentricity of the bore is amplified at P, fed to phase-sensitive detector D and indicated at M.

In lieu of the box, an insulating band carrying a metal band may be arranged around the indicator cylinder the piston of which is provided with a metal plate which makes contact with a metal pointer carried by the metal band. A switch for restarting may be arranged in the magneto connection.
Patent GB-770855-A (GB)
Title: Improvements in or relating to process of recovering glutamic acid
Filed: 1955-06-23
Abstract: Glutamic acid is recovered from Steffen's filtrate by treatment with sulphuric acid to precipitate inorganic sulphates, hydrolysis with a non-oxidizing mineral acid (e.g. hydrochloric), separation into fractions A and B (A containing 20-60 per cent of the hydrolysate), treatment of B with alkali to give a pH of 4-6, separation of insoluble material, concentration at least to point of incipient crystallization of salts, separation of the salts and addition of sufficient A to give a pH of 3.2.  Betaine hydrochloride may be separated by adding hydrochloric acid to pH 0.2-1.0 after precipitation of sulphates but before hydrolysis. The initial Steffen's filtrate is preferably concentrated to S.G. 1.2-1.4 and addition of sulphuric acid made to bring the pH to 2.0-2.9, preferably 2.6.  The separation into fractions may be done by filtration so that A contains, for example, 20-40 per cent of the liquid and B contains the solids and the remainder of the liquid. The solids (mainly humin) may be filtered off at this point or may be left until crystallization occurs; the concentration to effect this is preferably carried on until the solution has a viscosity of 325-425 (e.g. 375) centipoises. After mixing of the solutions at pH 3.2 glutamic acid crystallizes on standing.  It can then be pulped with water to remove residual inorganic salts and converted to monosodium glutamate.  Examples are given of the process.

In a Bourdon pressure gauge having a pointer a<SP>6</SP> rotated over a calibrated dial by the distortion of the pressure tube A, the free end of the pressure tube A is formed with a projection A2, Fig. 2, capable of engaging an adjustable resilient arm b<SP>2</SP> affixed to the frame A<SP>1</SP> of the gauge, the movement of the pressure tube A being restricted when the projection A<SP>2</SP> engages the resilient arm b2. This arrangement enables part of the dial range to have a different scale from the remainder of the range. The resilient arm b<SP>2</SP> may be part of a U-shaped member B<SP>1</SP> secured to a slotted arm B, a screw b<SP>1</SP> passing between the legs of the member B<SP>1</SP> and through the slotted arm B so that by adjusting the position of the screw b<SP>1</SP> the effective length of the resilient arm b<SP>2</SP> may be varied.

[Class 38 (ii)] The temperature of each winding 14, 15, 16 of a three winding transformer is indicated by an arrangement comprising three thermometers 22, 23, 24 the bulbs of which are immersed in the transformer tank and each associated with a resistance heater 25, 26, 27 through which currents proportional to the ampere-turns of the respective windings are caused to flow by connecting the heaters in the manner shown to two current transformers 20, 21 associated with the windings 15, 16. The current transformers are connected so that their voltages are additive in the circuit comprising the heaters 25, 26, and are arranged so that when no current flows in the winding 14 and the ampere turns of the windings 15, 16 are equal, the currents in the heaters 25, 26 are equal and no current flows in the heater 27. Thus when current flows in the winding 14, and the ampere turns of the windings 15, 16 become unequal, a current proportional to that in the winding 14 appears in the heater 27.

Abstract: Hydrocyanic acid is adsorbed and stored by substances such as activated charcoal and silica gel which have high adsorptive powers, the product being used for disinfecting and similar purposes.  The acid may be adsorbed in the liquid or gaseous state and may be selected from mixtures of gases containing hydrocyanic acid.

Liquids which have disinfecting and/or irritating properties and which may also adsorb the acid may be added to enable the presence of the hydrocyanic acid to be detected.  Tear gas such as chloro-carbonic acid ethyl ester and chlor-acetone are mentioned. The adsorption is assisted by cooling the product, and steam may be added.  The hydrocyanic acid is given up slowly from the product.ALSO:Substances having high adsorptive power, such as activated charcoal or silica gel are used to adsorb hydrocyanic acid in either the liquid or the gaseous state.

Abstract: 167,465. Choppinet, J., Gillon, G., and Defays, V. Aug. 5, 1920, [Convention date]. Shaft couplings.-In a coupling for rods and other members, particularly applicable to drilling-apparatus in which the drilling- tubes s deviate from a straight line, one coupling- part A carries a cylindrical head T engaging a cylindrical recess in the other coupling-part B, endlong movement in the recess being prevented by means of a lug on the head T engaging a recess in the part B and by the engagement with a peripheral groove K in the head T of blocks E engaging a non- circular recess L in the part B. The blocks are moved by a screw D, axial movement of which is prevented bv a screw F, into engagement with the head T so as to force it frictionally into engagement with the walls of its recess. Considerable lateral pressure, however, on either of the coupling parts overcomes the frictional action, relative rocking about the axis of the head T taking place. Peripheral recesses in the part A are provided, for allowing the free suspension of the assemblage of rods from any stand having points adapted to fit the recesses when the deflection of the rods is to be measured.

Patent GB-1046575-A (GB)
Title: Graft polymers of chlorinated ethylene polymers
IPC: C08F8/20
Filed: 1965-05-03
Abstract: Graft polymers are made by heating chlorinated polyethylene which has sites thereon activated for free-radical polymerization with at least 5% by weight of a vinylidene monomer in a liquid reaction medium. The activation of the chlorinated polyethylene may be effected by chlorinating polyethylene in the presence of oxygen or hydrogen peroxide, or by ozonizing chlorinated polyethylene.  Monomers specified are styrene, methyl, ethyl, hydroxyethyl and glycidylmethacrylates, acrylonitrile, acrylamide, n-octyl acrylate and divinylbenzene.  Polymerization may be carried out in aqueous suspension or in solution, e.g. in toluene. When polymerizing in aqueous suspension it is preferred to have present a solvent, e.g. methanol, which is a non-solvent for the chlorinated polyethylene, thereby minimizing the formation of vinylidene monomer homopolymer.
