Title: Nuclear reactor fuel pin and apparatus for sensing density pressure or concentration of a gas
Inventor: MAIDMENT LESLIE
IPC: G01N9/00
Filed: 1965-04-14
Abstract: 1,120,582. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 13 April, 1966 [14 April, 1965], No. 16108/65. Heading G6C. [Also in Division G1] A nuclear fuel pin comprises means for determining the density, pressure or concentration of the fission gas in the voidage space of the nuclear fuel pin, the means comprising a loose fitting piston which is moved through the voidage space at a rate dependent on the density of gas in the voidage space and means for sensing the completion of the movement of the piston. The piston is magnetic and is lifted through the voidage space by an electromagnet mounted towards the top of the voidage space. The electromagnet is energized to raise the piston under the known bias of the magnetic attraction creating a flow of gas through the clearance between the piston and voidage space. An acoustic transducer is connected to the fuel pin to detect when the piston strikes against the top of the voidage space to record the time of movement of the piston. Alternatively the time taken for the piston to fall could be recorded.

Title: Improvements in or relating to the production of films, foils, thin sheets and the like
IPC: C08L1/08
Filed: 1935-06-05
Abstract: <PICT:0436784/IV/1> In a method of reducing the tendency to curl of films or foils, produced by depositing a film-forming solution on a support, evaporating volatile solvent from the deposited solution and stripping the film or like product from the support, the film, or foil is subjected to the action of heat applied only to or in greater quantity to the air side of the film, i.e. that side of the film which is not in contact with the support during the film formation. The heat treatment is preferably effected by passing the film over heated surfaces, e.g. of polished metal drums.  The air side of the film may be subjected to a higher temperature than the other side or may be heated for a greater length of time. The films preferably have a basis of cellulose derivatives containing a suitable plasticizer in the proportion of 10--75 per cent of the cellulose derivative. Suitable compositions for the formation of films are (1) cellulose acetate 100 parts by weight, triphenyl phosphate 15, diethyl phthalate 15, acetone 300, methyl alcohol 50; (2) cellulose acetate 90, cellulose nitrate 10, dibutyl tartrate 15, ethylene dichloride 300, methyl alcohol 50, ethylene glycol mono-methyl ether 15; (3) cellulose nitrate 100, diethyl phthalate 15, butyl alcohol 15, ethyl alcohol 190, ether 130; or (4) cellulose nitrate 100, camphor 10--50, acetone 190, alcohol 130.  In suitable apparatus for carrying out the invention, a film 1 is cast on the wheel 2 stripped by the roller 3, and led under a drum 4, over a drum 5 and under a drum 6.  The air side of the film contacts with drums 4, 6 and the other with drum 5. A pipe 8 leads a heating fluid such as steam to drums 4, 6.  Drum 5 may be heated or not.  Drums 4, 6 may be of larger diameter than drum 5, the temperatures then being equal.  The drums may be heated electrically.  The apparatus may be installed in the driers of the film-forming machine, or may be used for flattening fully seasoned films.  The results of tests are quoted to show that the films remain flat substantially permanently after treatment.

[Class 40 (iv)] [Also in Group XXXV] A D.C. saturated inductance 1 acting as a relay and having a self excited winding 4, fed over a rectifier arrangement 7 by the traversing alternating current, and one or more independent D.C. saturating windings 5, 6 is arranged, when the winding 5 is energized through resistance 10 to oppose the winding 4, to pass either of two values of the traversing alternating current. If contact 11 is closed to increase the effect of winding 5, then on opening of this contact the inductance 1 permits the passage of the lower of the two values of the alternating current referred to above. The higher value is obtained by momentary closure of contact 12 to energize winding 6 which acts cumulatively with winding 4 and this higher value is sufficient to operate a device 2 in series with inductance 1 which device may be a signal bell or releasing coil or may comprise a rectifier in combination with a further D.C. saturated inductance. In another arrangement, Fig. 3 the winding 6 is omitted and the winding 5 is arranged to be connected to the rectifier arrangement 9 supplying it through push button switching means 15, 16 whereby it can be connected either to assist or to oppose the effect of winding 4. The winding 4 has a glow discharge tube 14 arranged in series therewith and is shunted together with this tube by a resistance 13. Alternatively the discharge tube 14 and resistance 13 are omitted, the rectifier arrangement supplying winding 4 having a saturable core inductance connected in its alternating current circuit and being shunted together with this inductance by an air cored inductance.

Abstract: 668,871. Casting composite articles; casting processes. STEEL CO. OF WALES, Ltd. May 19, 1950 [June 23, 1949], No. 16728/49. Class 83 (i). Steel ingots, suitable for rolling, are made by pouring commercial rimming or effervescing steel until the mould is over half filled and then introducing deoxidizing metal while pouring the remainder. About 84 per cent of the mould capacity may be filled first and, after a short pause, to allow rimming to commence, the remainder is poured with the de-oxidizer which controls the rimming action and gives a non- ageing steel except for the surface layer. This gives a satisfactory surface in sheet rolled therefrom so that it is suitable for deep drawing. The deoxidizer may comprise aluminium shot, 3 lbs. per ton of ingot, and be introduced into the stream of metal being poured about one inch above the surface in the mould.

Filed: 1939-06-08
Abstract: 529,760. Fluid-pressure servomotor-control systems. BRYCE, Ltd., and GARRETT, H. A. June 8,1939, No. 16798. [Class 135] A speed governor particularly adapted for use with internal combustion engines of the fuel injection type adapted to operate over a wide range of speeds comprising a spring loaded plunger subject to the pressure generated by a displacement pump driven at engine speed has a manually controlled leak-off for varying the control point and has means brought into and out of operation dependently on the control of the variable leak-off to modify the response of the spring-loaded plunger at a particular point in the speed range thereby to bring about greater percentage run-up at lower speeds with respect to the run-up at higher speeds. In the arrangement shown in the Figures the control rack 2 of a fuel injection pump 1 is operated by fluid from an engine-driven pump 13 acting on a plunger 3 against the action of a spring 6. A main leak-off port 12 leading from the pipe line connecting the pump to the plunger is controlled by a manually operated rotary cylindrical valve 8 having an inclined port adapted to co-operate with the port 12 and connected by radial and axial passages 16a, 16 with a pipe 18 leading to the suction side of the pump. An auxiliary leak-off port 20 formed in the wall of the cylinder for the plunger 3 is obturated by the inclined end of the plunger and leads by way of ports and passages 28, 29 16 in the manually controlled valve to the suction side of the pump. A rotatable plate 21, clamped in place by a ring 24 and nuts 25 has an eccentric pin 22 engaging a hole in the plunger for adjusting the angular position of the plunger. In this form the passage 29 is arranged to communicate with the port 28 and the port 20 made operative when the main leak-off port is adjusted to its minimum position. In a modification the inclined plunger end is replaced by a groove at the other end of the plunger with one inclined wall and the auxiliary leak-off is made operative when the main leakoff is in its maximum position. In a further modification the auxiliary leak-off port is replaced by an auxiliary loading spring acting on the plunger and subject to the pump delivery pressure, when supplementary ports in the variable throttle valve are brought into engagement. According to the Provisional Specification the plunger may have an axially extending projection wholly or partly tapered displaceable into and out of an auxiliary leak-off chamber. The outlet from this chamber extends to the return duct by way of two ports in the bearing for the spindle of the variable leak-off valve. This valve comprises a camshaped plate moved more or less over a discharge orifice.
