A nuclear fuel assembly comprises an array of spaced, parallel nuclear fuel pins supported by means of spacer grids at intervals along their length. Each spacer grid is composed of serpentine locating strips 14 interconnected by means of egg box type slots. The strips form the sides of generally rhombic pockets and midway along each side of each pocket there is a sinuosity 35 in the strip. This sinuosity comprises a straight length 36 lying along the line joining the centres of two adjoining pockets and curved pieces 37 blending the straight length 36 into the remainder of the strip. A support grid at the bottom of the assembly comprises a number of parallel strips which fit into open ended slots in the bases of the fuel pins and a number of rods which penetrate diametric holes in the pins. The ends 21 of the strips and rods are cranked at 22 so that they are parallel to each other and threaded into holes 23 in two casing parts 24, 25 which are slid along the ends 21 and then welded along their adjacent edges 33 to form an integral casing. The ends of the strips and rods are secured by brazing or welding to the casing.

Title: Improvements in chlorine containing derivatives of dicarboxylic acids
IPC: C07C69/34
Filed: 1948-08-25
Abstract: Dehydrobrominated adducts of formula <FORM:0653479/IV (b)/1> where R is alkyl, A is a substituted or unsubstituted hydrocarbon radical free from carbonyl double bonds and nitrile triple bonds conjugated with respect to the ethylenic double bond, B is a group-(CH2)n.H, where n is zero or an integer less than the number of skeletal carbon atoms in radical A, and D is hydrogen or methyl, are prepared by treating a mixture of trichlorobromomethane, a dialkyl ester of fumaric or maleic acid, and an unsaturated compound CDA=CHB either with actinic light or with a peroxidic polymerization catalyst at a temperature at which it decomposes to give free radicals.  It is preferred that R is lower alkyl, i.e. having 1-6 carbon atoms, and B is hydrogen; CDA=CHB is then, e.g., butene-1, heptene-1, butadiene, methallyl chloride, allyl alkyl ethers, diallyl, allyl esters of acids, and alkyl esters of vinylacetic acid or undecylenic acid. CDA=CHB may also be hexene-3, pentene-2, and alkyl esters of oleic acid.  It is stated that the reaction proceeds via the 1 : 1 : 1-adduct <FORM:0653479/IV (b)/2> and also that the dehydrobrominated product may be formed from this by heating either in the absence or presence of dehydrobrominating agents such as alkali metal alcoholates.  In the examples, bromotrichloromethane and dimethyl fumarate are together condensed with (1) octene-1 to give methyl 3-carbomethoxy-4-hexyl - 6 : 6 : 6 - trichlorohexenoate -2, reaction of which with sodium methoxide gives a -(1-carboxy-2-octyl)-fumaric acid; (2) butadiene; (3) styrene to give methyl 3-carbomethoxy-4-phenyl - 6 : 6 : 6 - trichlorohexenoate - 2; (4) allyl chloride to give methyl 3-carbomethoxy-4 - chloromethyl - 6 : 6 : 6 - trichlorohexenoate - 2; and (5) propene.  In all cases the products are hydrolysed to the tricarboxylic acids as in (1).  The Specification as open to inspection under Sect. 91 comprises also the use of the olefinic compound butene-2, and any bromomethane of formula CBrX2Y, where X is chlorine, bromine or fluorine, and Y is chlorine, fluorine, hydrogen, carbalkoxy or carbonitrile.  The reaction is not limited with regard to temperature.  This subject-matter does not appear in the Specification as accepted.

IPC: B41L47/02
Filed: 1949-08-31
Abstract: 684,235. Index tabs. ADREMA, Ltd. Aug. 17, 1950. [Aug. 31, 1949 ; May 9, 1950] Nos. 22586/49 and 11525/50. Class 16. [Also in Group XVI] A tab to engage in, and project from, the hollow edge of a printing plate for use in addressing or like printing machines, comprises a blank of resilient sheet metal folded over upon itself, one of the limbs (2b) so formed having its end turned in the direction away from the other limb (2d) to form a locking tongue (2c), and the other limb (2d) having its side edges turned in the directions towards the first limb to form side lugs (2e), whereby upon the tab being inserted into an edge slot of the plate, the tongue springs into a locking slot in one of the side walls forming the hollow edge of the plate to prevent withdrawal of the tab, the side lugs fitting in the edge slot to increase the rigidity with which the tab is held. The tab may be of copper-beryllium alloy. For insertion, the limbs are pressed together, the lugs 2e engaging the sides of the slot, and when inserted the main lower portion 2d of the rear limb may bend backwards or the lugs 2e may score grooves in the sides of the slot, according to the width of the hollow portion of the plate. A molehill 2h is bowed out of the tab to engage the top of the slot. The tab may be of double or greater length to fit into a plurality of slots when the cut-away parts 2j become recesses to fit over portions of the plate between slots. In this case there is a molehill and tongue for each slot, but only two lugs 2b. In another form the rear limb 2d extends lower than the limb 2b. Suitable printing plates for use with the tabs are described (sec Group XVI). According to the first Provisional Specification, vertical upwardly tapering ribs may be formed in the rear limb, and the lower edge of the front limb may be bent back before being bent forwards to form the tongue, the lower edge of the rear limb being cut away to accommodate the horizontal ridge thus formed. Specification 684,300, [Group XVI] is referred to.

Abstract: 1,153,608. Coating apparatus. GILLET THAON. 13 May, 1968 [16 Feb., 1968], No. 22628/68. Heading B2L. A gelatine film, mounted on a plastics sheet and carrying a negative image, is transferred to the surface of a copper cylinder, subsequently to be engraved, by apparatus comprising bearings for said cylinder mounted for transverse movement from an operative position to a position permitting cleaning of said cylinder, a presser roller carried by vertically-movable bearings, means for raising and lowering said bearings to apply a predetermined pressure to said cylinder, means for rotating the presser roller, and a table adapted to support said backing sheet for permitting the introduction thereof between said roller and cylinder. A cylinder C, to be engraved, is mounted in bearings movable transversely on slides 1 from an operative position in which cylinder C is engaged with a rubber-covered presser roller P to a retracted position in which cylinder C may 'be de-greased and cleaned, the products of cleansing being received in a container 18. Roller P is journalled in bearings 4 vertically movable on slides 5. A screw 24, carrying a handwheel 8 and passing in screwthreaded engagement through a lever 6, is rotatably attached to each bearing 4. Each lever 6 is pivoted at 22 to the machine frame and at 23 to the piston rod 6' of a double-acting pneumatic jack 7. Parallelism between roller P and cylinder C is obtained by manipulation of handwheels 8. The pressure exerted by roller P is governed by the air pressure applied to the jacks 7 via a reducing valve 10. A coated backing sheet F is supported on a table T and is held in adjusted position by solenoid-operated clamps 16. Table T is slidable in guides 14 and is tiltable by means of a telescopic strut 32 for correctly positioning the inner end of sheet F in the nip of roller P and cylinder C. On starting the machine, roller P is driven by roller and pulley means 25 from a motor 12, the clamps 16 are released, and warm water is sprayed on to cylinder C from a perforated pipe 17 mounted under the leading edge of table T. The gelatine film thereby adheres to cylinder C and separates from the backing sheet.

Abstract: 1,176,075. Lateral transistors. SPRAGUE ELECTRIC CO. 16 May, 1967 [17 May, 1966], No. 22660/67. Heading H1K. In a lateral transistor the emitter region is formed in the lateral surface of a recess, the base of the recess being covered by a non- conductive mask. This reduces the area of the emitter junction which does not face the collector region, and thus increases the current gain. As shown, Fig. 4, a lateral transistor is produced by etching a cavity 22 in one face of an N-type silicon wafer 21, covering the bottom of the cavity with a silicon dioxide mask 24 and diffusing a P-type emitter region 26 into the wall of the cavity and a P-type collector region 25 into the surface of the wafer surrounding the cavity. Emitter, base and collector contacts 26<SP>1</SP>, 27<SP>1</SP> and 25<SP>1</SP> are then applied.

Abstract: 378,642. Directive wireless signalling. RADIO-AUSTRIA AKT.-GES., 14, Renngasse, Vienna. Aug. 11, 1931, No. 22707. Convention date, March 6. [Class 40 (v).] A directional aerial system comprises groups of coaxial horizontal dipoles arranged one behind the other at a distance of substantially half a wavelength in the main direction of radiation each number of a group being excited cophasially from the wires of a parallel wire feeder with uncrossed conductors and the groups having alternately opposed phases. Groups of dipoles 1, 11, Fig. 1, are arranged at half wavelength intervals apart and excited from a parallel wire system 2, 3 fed through a coupling device 4 and carrying standing voltage waves. The main directions of radiation are shown at X. Two or more such systems may be arranged side by side and fed from a common source. Impedances 6, Fig. 4, or tuning or coupling elements may be inserted in known manner in the individual dipoles or sections 5, Fig. 3, of the dipoles may be bent back upon themselves. The system may be arranged so as to constitute one or more closed loops as in Fig. 4 so that hoar-frost and ice may be dispersed from it by the passage of a heating current, and to ensure constant current intensity of the H.F. currents in all the branches. For compensating any asymmetry and for exact adjustment of the voltage antinodes, loops 9, Fig. 5, of variable magnitude may be provided. The groups of dipoles may be arranged at different heights rising towards the favoured radiation direction which gives an increase in that direction and a decrease in the opposite direction; and also produces radiation at a steeper angle with the ground which is said to be an advantage for long distance communication. The groups may be arranged in planes one above the other and some may be excited by induction.

Title: Improvements in or relating to automatic weight recording devices for use in weighing machines
IPC: G01G23/18
Filed: 1932-08-15
Abstract: 389,383. Weighing-apparatus. SEITZWERKE GES. and DEPENBROCK, W., 3, Heinrichstrasse, both in Kreuznach, Germany. Aug. 15, 1932, No. 22842. [Class. 143.] Printed records, apparatus for giving.-Relates to an automatic weight-recording printing device for use with a weighing machine of the kind wherein type discs are adjusted by means of a rotary stepped disc and a finger or feeler the stepped disc lacking a step corresponding to the highest number or numbers on the type disc, and consists in compensating for the absence of the step by providing an auxiliary controlling device actuated from some other movable part of the machine, for setting the type disc in a position corresponding to the actual load. In Fig. 1 is shown the printing arrangements of a machine wherein the point of maximum load on the dial, viz. 400 kgs. coincides with the zero position. When the machine is in operation, a cam shaft 8 is rotated in known manner to slide a feeler 11 to the left and to slide a feeler 18 to the right. If the load is below the maximum the feeler 11 is arrested by a curved extension 3 of the weighbeam 1 and the feeler 18 engages the stepped disc 17 and sets the type disc 22 by means of a rack 20. If however the maximum load is on the machine, thus imparting a complete rotation to the stepped disc 17 and thereby restoring it to zero position, the beam 1 is sufficiently depressed for the feeler 11 to pass above the extension 3 and permit a rod 13 to descend. In its lower position the rod 13 presents a stop 28 in the path of a projection 29 on the feeler 18 and restricts the forward movement of the feeier so that the maximum digit is set on the type disc 22. To ensure accurate descent of the bar 13 a nose 15 sliding on a control disc 16 drops into a recess 16b at the critical point. In machines where capacity weights 30, 31, 32, Fig. 2, are placed on the beam 1 to increase the weighing range, a similar arrangement of mechanism may be used. In this case, the feeler 11, instead of abutting against an extension of the beam, abuts against those capacity weights which have not yet been placed on the beam, and the feeler 11 is provided with a series of steps for the rod 13 to rest upon. The upper end of the rod carries a stepped member interposed between the rack of the type disc and the feeler of the stepped disc so as to vary the setting of the type disc to correspond to the added capacity weights. In a modification, the distance between the rack of the type disc and the feeler of the stepped disc is varied according to the number of deposited capacity weights by means of an interposed spindle with oppositely screwed ends, actuated by a rack on the rod 13. In a further modification, the distance is varied by a toggle linkage actuated by the rod 13.

Abstract: 881,929. Cutting-machines. RUHRMANN, J. July 3, 1959 [Aug. 16, 1958], No. 22879/59. Class 31 (1). [Also in Group XXII] In a machine for removing coupling elements, formed by a continuous filament, from a continuous carrying tape of a sliding clasp fastener stringer, the tape is fed past at least one rotary cutting disc which severs the coupling elements. The tape is fed by a roller 7 over guide rolls 22, 24, 25 and a tensioner 26 between a pair of cutting discs 16, 17 having cutting edges along a portion of their peripheries. The discs 16, 17 are drivingly coupled for one revolution to the shaft 5 of the feed roller 7 by release of a spring- loaded detent 14 by energization of a solenoid 19 controlled by a switch 20 actuated by a cam 21 geared to the shaft 5. Adjacent the discs 16, 17 the tape is guided by a deflector 40 which causes the coupling elements to project from the tape. The severed coupling elements are ejected from the retaining stitches by fingers 28 on an arm 29 oscillated when a switch is actuated by the cam 21. Alternatively, the tape may be passed by an ejector having inclined faces which remove the severed coupling elements. In a modification, a single cutter disc co-operating with a guide roller is used.
