Title: Improvements in and relating to devices for suspending electric conductors
IPC: H02G7/05
Filed: 1930-07-11
Abstract: 354,955. Suspending cables. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hawley, K. A.; c/o Locke Insulator Corporation, P.O. Box A, Baltimore, U.S.A.) July 11, 1930, No. 21061. Convention date, July 11, 1929. [Class 36.] A suspension clamp for an overhead cable 1 comprises a cable-carrying cradle 2 pivoted to suspension links 14, relative rotary motion between the cradle and the suspension links causing a clamping member 8, which is resiliently connected to the cradle 2, to decrease its clamping action on the cable, so that the clamp will release the cable in the event of breakage of the cable. In the construction shown in Figs. 1 and 3, the clamping member 8 is retained in the cradle 2 by U-bolts 11 which engage yielding extensions 10 formed on the member 8 and pass through bosses 4 formed on the cradle to receive nuts 12 and spring washers 13. The suspension links 14 are formed with elongated holes 15 to receive the trunnions 6 of the cradle 2, downwardly extending heads 7 being provided on the trunnions to prevent lateral displacement of the links 14. The links 14 are formed on their inner faces above the holes 15 with shoulders 17 adapted to engage pairs of laterally projecting lugs 18 formed on the clamping member 8. Relative motion between the suspension links 14 and the cradle 2 causes the shoulders 17 to bear on one pair of the lugs 18, thereby raising the clamping member 8 and releasing the cable. In a modified construction the U-bolts 11 which clamp the member 8 to the cradle 2 are replaced by J-bolts. Specification 291,968, [Class 36, Electricity, Conducting &c.], is referred to.

Title: Process for the epimerisation of diastereoisomeric amino diols
Inventor: HEYWOOD BASIL JASON
IPC: C07D263/14
Filed: 1950-08-25
Abstract: Epimerization of erythro - 2 - acylamino - 1 - nitrophenylpropane - 1 : 3 - diols (optically active or racemic) is effected by forming a dinitric ester thereof, treating this with alkali to hydrolyse the 1-ester group with cyclization to an oxazoline, opening the oxazoline ring by the action of acid, treating the resulting propanol with alkali to hydrolyse the 3-ester group and again form an oxazoline ring, opening this by the action of acid and finally neutralizing the reaction mixture with a base.  The acyl radical in the 2-acylamino substituent may be, for example, a lower aliphatic acyl radical (acetyl being mentioned in the Provisional Specification), a halogenated lower aliphatic acyl or a benzoyl radical.  The formation of the dinitric ester of the erythro diol may be effected by treating this compound with nitric acid (s.g. 1.50) at about 0 DEG  C. (not above 5 DEG  C.), or by the method illustrated in example 1 below. The remaining stages are likewise preferably carried out in the cold, the alkali treatments advantageously in aqueous alcohol.  In examples (1) the dinitric ester of DL-erythro-2-dichloracetylamino - 1 - o - nitrophenyl - 1 : 3 - diol is prepared by treating DL-erythro-5-di-chloracetylamino - 4 - phenyl - 2 - methyl - 1 : 3 - dioxan with nitric acid (s.g. 1.50) at a temperature rising from -40 DEG  to 0 DEG  C. and is treated with aqueous methanolic caustic soda, the resulting oxazoline is treated with concentrated hydrochloric acid, the last two steps are repeated and the final reaction mixture diluted and neutralized with solid sodium bicarbonate; (2) DL - erythro - 2 - dichloracetylamino - 1 - p - nitrophenylpropane - 1 : 3 - diol is treated with nitric acid (s.g. 1.50) at a temperature rising from -30 DEG  to +10 DEG  C., and the resulting dinitrate treated as in (1); the caustic soda in the first alkali treatment may be replaced by caustic potash, potassium carbonate or triethylamine and the sodium bicarbonate in the final neutralization by ammonia; (3) the DL-compound in (2) is replaced by the L-isomer, the final product being chloramphenicol; (4) the aqueous methanolic caustic soda in the second alkali treatment in (2) is replaced by aqueous caustic soda, and the product is further treated without isolation. Specification 692,265 is referred to.  The Provisional Specification comprises generally the epimerization of compounds of the general formula <FORM:0699808/IV (b)/1> wherein R3 and R4 are the same or different and each represent a hydrogen or halogen atom or a lower alkyl or alkoxy radical, R5 represents hydrogen or a nitro group and R6 an acyl radical.  Specification 673,864 also is referred to.

Title: Nuclear reactor fuel elements
Inventor: SAUNDERS ALLAN CHARLES ANTHONY
IPC: G21C17/10
Filed: 1963-05-28
Abstract: 1,075,633. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. May 13, 1964 [May 28, 1963], No. 21375/63. Heading G6C. A fuel element of the type comprising fissile material enclosed in a protective sheath and having positioning members projecting from the sheath for engagement in longitudinal grooves in a reactor fuel channel has spring locating means for preventing vibration in one direction transversely of the fuel element, said means being carried by one or more of the positioning members and each bearing against one wall of said groove. The vibrations are caused by coolant flow, and the clearance is necessary between the positioning members and the grooves to ensure easy withdrawal of elements from the channels. The springs 28 (Fig. 6) are mounted on the sides of the positioning members 19 (see also Fig. 4) by means of rivets 26. It is preferable to include some means of preventing the springs from jamming a fuel element if they break at the point of contact; one such means comprises a spring 33 of weak opposing tension secured to the spring 28 by wire 34. If the spring 28 breaks, the spring 33 bows inwards, thus withdrawing the broken ends from the jamming position. Alternatively, a stainless steel shoe may be fitted over the spring 28 (Figs. 7, 8, not shown) to hold the broken ends in their unbroken. position. An alternative form of vibration preventing spring (Figs. 10, 11, not shown) comprises a helical compression spring mounted across the width of the fuel element ends, the ends of the spring each bearing on angle faced plungers which in turn force angle faced locating. members into engagement with the channel groove walls. The fuel element comprises natural uranium 1 in a herring-bone finned magnesium alloy can 2. Sintered alumina thermal insulators 16 are placed between the fuel 1 and end cap plug 6, seal welded to the can at 9. The end plugs 6 and fuel 1 are grooved, and the can 2 is pressed into these grooves, after assembly, by external pressure. End fittings 11, 13 are welded to the cans and have V-shaped recesses and projections respectively for axial load bearing contact. A graphite block 10 is placed between each lower end fitting 13 and the recessed end plug 6, so that after initial creep distortion of the end cap 13, the compressive load is taken by the creep resistance graphite block 10, thus obviating any possibility of radial forces ultimately splitting the seam weld 9. A further feature which reduces the possibility of seam weld failure is that lifting lugs 37 are integral with the canning, instead of being a part of the end plugs.
