Title: Construction of continuous electrode for a reduction cell
IPC: C25C3/16
Filed: 1962-03-27
Abstract: In an electrolytic aluminium furnace the vertical Soderberg-type anodes 3 are held by interlocking horizontal members 145, 157 made of aluminium and movable vertically with the anode, and each provided with projections 21 or similar members engaging the anode, and preferably acting as electrical connections thereto.  The horizontal members 145, 157 are connected to end members 147 to form a continuous frame or the unit may be a one-piece aluminium casting. The frame members are supported by jacks 171 and link members, attached thereto, and as the carbon anode 3 is consumed, the frame and anode is lowered, the jack links 186 being connected to the next frame member, the freed bottom member then dissolving in the electrolytic melt.  New frame members and anode blocks are added to the top of the assembly.  The details described and illustrated (but not shown) include (a) the V-shaped cross-section to the interlocking frame <PICT:0990647/C6-C7/1> members may be channelled in other forms, e.g. a tongue and groove, (b) the projections 21 securing the frame members to the anode may be of aluminium integrally cast with the frame, or may be steel or aluminium studs inserted in holes in the frame; the projecting ends 36 may be formed to receive electrical conductors. A number of alternative stud designs are given, including a steel stud secured by casting aluminium metal around the stud inserted in an opening.  When the aluminium softens and melts, the stud is readily released.  In another form the studs are integrally cast with the frame member.  The frame members may be provided exteriorally with inclined fins to conduct away the heat, and also surrounded by a hood to collect furnace fumes.  The aluminium frame members may also be supported by vertical channel and rib elements to form a slideway.  A number of forms of flexible conductors and attachments are also described.

Title: Improvements in or relating to lasers
IPC: H01S3/223
Filed: 1964-03-19
Abstract: 1,027,920. Lasers. C.S.F.-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 19, 1964 [March 27, 1963], No. 11623/64. Heading H3B. A hydrogen laser utilizes the transition between the second lowest level of parahydrogen and the lowest level of orthohydrogen. Hydrogen liquefied at 8 is pumped through coil 9 and tank 10 containing a paramagnetic catalyst 12 for converting orthohydrogen into parahydrogen before being evaporated and heated to the surrounding temperature by re-heating device 13. The gas then passes into Fabry-PÚrot resonator 1 where stimulated emission occurs due to transitions between the L = 2 and L = 1 levels, the latter level corresponding to orthohydrogen, so that the parahydrogen molecules are converted into orthohydrogen during the lasing action and are evacuated through section 6 before being returned to the cooling circuit. Q switching may be achieved by using a Kerr cell to vary the effective reflectivity of the mirrors 2, 3. In the arrangement of Fig. 2 (not shown) a heat exchanger is disposed between the descending line section 6 and the rising line section 11.

Abstract: 350,136. Road vehicle springs. FOSTER, C. H., 1573, East 21st Street, Cleveland, Ohio, U.S.A. April 14, 1930, No. 11808. Convention date, Aug. 5, 1929. [Class 108 (ii).] With the object of preventing shimmying of the steering wheels of a motor vehicle, the spring connections to the axle on one side of the vehicle allow a limited fore-and-aft rocking movement while the spring on the opposite side is rigidly bolted to the axle. In the construction shown in Fig. 3, the spring 2 is held between curved plates 7, 14, the whole being clamped to the axle 5 by U-shaped clips 10 in such a way that the spring 2 may rock slightly on the axle but with a certain amount of resistance to such movements. In the modification shown in Fig. 6, the leaves are formed with a number of inter-fitting transverse ribs, the rib on the lower leaf bearing directly on the axle 17 while the depression on the upper leaf is engaged by the clamping plate 18. In a further modification, shown in Fig. 7, the ribs project upwards and the lowest leaf rests upon a transverse circular bearing member 20, resting in a recess in the axle. In this construction helical springs 21 ensure that the U-shaped clips 10 shall clamp the spring resiliently to the axle.

Title: Improvement in ethers of esters of lactic acid
IPC: C07C69/68
Filed: 1945-05-11
Abstract: Ethers of lactic acid esters are produced by heating a di-acetal of pyruvic aldehyde at above 100 DEG  C. in the presence of an acid catalyst such as hydrochloric, sulphuric, phosphoric and sulphonic acids, and an alcohol.  Instead of the di-acetal, there may be used its components, viz. pyruvic aldehyde and more than two molar proportions of alcohol.  The acetal may have the formula CH3.CO.CH(OR)2, where R is alkyl, alkoxy-alkyl, aroxy-alkyl or aralkyl, and the alcohol may correspond to the alkyl or substituted alkyl group thereof.  Specified acetals are the di-ethyl, isopropyl, butyl, 2-ethyl-hexyl, lauryl, methoxy-ethyl and b -chlorethyl acetals, the corresponding ether of lactic acid ester being ethyl 2-ethoxypropionate, isopropyl - 2 - isopropoxypropionate, butyl 2-butoxypropionate, 2 - ethylhexyl 2 - (2 - ethyl - hexoxy) - propionate, lauryl 2 - lauroxypro - pionate, methoxyethyl 2 - methoxyethoxy - propionate and b -chlorethyl a -b -chlorethoxy-propionate.  The products may be separated by selective acid hydrolysis of the unconverted acetal followed by fractionation or recovered as lactic acid ethers by saponification with alcoholic alkali metal hydroxide followed by addition of mineral hydroxide followed by addition of mineral acid.  They are useful as solvents and plasticisers for vinyl resins and cellulose esters and ethers. In examples, sulphuric acid is the catalyst used, temperatures being 130-150 DEG  C.

Abstract: 129,466. Japy, A. P. July 19, 1918. Periodic counter and like speed indicators.-An increment proportional to that to be measured is conveyed to the pointer through a planet pinion carried by a sleeve, upon which is mounted loosely a brake drum in gear with the planet wheel, and which has attached to it a second brake drum transmitting motion to a third brake drum carrying the pointer. The wheel 1, Fig. 1, loose on the shaft x is driven proportionately to the vehicle &c., the speed of which it is desired to measure. It gears with a planet pinion 2 carried by a sleeve also loose in the shaft x and in one with the drum 7. A drum 5 mounted loosely on the sleeve gears at 4 with the wheel 2, while a drum 10 carrying the pointer 12 is loose on the shaft x and is driven by a lug 9 on the drum 7 engaging a lug 11 on the drum 10. Both these drums 7, 10 have spiral springs which tend to return them to zero, a position defined by a stop not shown. The brakes are one-way band brakes operated by cams. The cams for operating the brakes are driven in any usual way for instance from a shaft driven at a constant speed. The cycle of operations is as follows. The drum 5 is held and the drive passes through the sleeve to the drum 7 which is free. The drum 10 meanwhile is locked by its brake and the pointer indicates the speed during the last period. If now the lug on the drum 7 catches up the lug on the drum 10, the pointer is moved to register increased speed. At the close of the interval, the drum 7 is held and drums 5 and 10 released, the drum 10 taking up a position defined by the lug on the drum 7, when it is again held by its brake, and the drum 7 released,

Title: Improvements in devices for detecting and identifying radioactive elements, in particular for geophysical prospection
Inventor: LALLEMANT CLAUDE
IPC: G01T1/178
Filed: 1960-04-07
Abstract: 931,515. Utilizing radiation detectors. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 7, 1960 [April 10, 1959], No. 12429/60. Class 40 (3). An apparatus for indicating the presence, and the relative proportions, of two or more gamma-ray emissive elements comprises a scintillation counter whose output passes to a pulse height analyzer unit. This unit provides two outputs corresponding to the pulse rates in two wide bands of the gamma-ray energy spectrum, these bands being so chosen that in one there is an energy peak of one of the elements which exceeds the energies of the second element in that band and in the other the second element shows a peak which exceeds the energies of the first element in this other band. The two outputs are passed to a ratiometer or a differential circuit whose output current feeds a pen recorder. A second track on the recorder indicates the total count rate over a further wide band which includes both the bands mentioned above. Gamma rays are detected by a scintillation detector 1 and photo-multiplier 2, Fig. 1. The photo-multiplier output is amplified at 3 and feeds discriminator and integrator units 5, 6, 7, 8. Unit 5 gives a signal proportional to the count rate over one energy band and units 6 and 7 to the count rate over two other bands: the two latter bands are selected to satisfy the conditions mentioned above. The signal from unit 5 is passed to a pen recorder 10, to produce a trace 16, while the signals from units 6 and 7 pass to a ratiometer or differential circuit 9. The unit 9 gives an output which decreases for increased counting rate in one of said bands and which increases for increased counting rate in the other band. This output is recorded as trace 17, Fig. 3. As the detector 1 is passed over samples, for example as in geophysical prospecting by air, trace 16 will show peaks 18, 19, 20, Fig. 3, indicative of increased total gamma count rate. The corresponding change in trace 17 indicates the element causing the increased count and its approximate proportion relative to the other element. Thus trough 21 corresponds to an increased count rate from unit 6, showing the presence of, say, thorium deposit. Likewise, the peak 22 shows the presence of, say, uranium, while the small peak 23, and large peak 20 of trace 16, show the presence of both thorium and uranium deposits, the latter slightly predominating.

Abstract: 703,543. Kinematograph apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 8, 1951 [May 19, 1950; June 10, 1950], Nos. 12542/50 and 14524/50. Class 97(1) Intermittent feed mechanism comprises a sprocket coupled to a driven shaft by a spring and means for holding the sprocket stationary while the shaft is rotated to tension the spring and means for releasing the sprocket to allow it to rotate under the energy stored in the spring, the sprocket holding means comprising a disc with a plurality of arcuate recesses round its periphery and a rotatable locking member co-operating with the recesses. In the form shown in Fig. 1, the shaft 3, carrying the sprocket 2, carries one end of a spring blade 10, the other being mounted in a sleeve 11 rotated by gearing 12, 13, 15, 16 from the driving shaft 17. The sprocket shaft carries a disc 18 with a series of arcuate recesses 19 in its periphery. These recesses co-operate with a segmental member 21, which is carried on the end of the shaft 17, and the member 20 which is driven from the shaft 17 by gearing 23, 24. The timing is such that the mem- 21 releases the disc 18 which is allowed to turn through 45 degrees before the member 20 arrests it. If both of the members 20, 21 were rigidly secured to their shafts this timing would not be achieved while the shaft 17 was accelerating initially. To take account of this the member 20 is allowed limited rotation on its shaft determined by the engagement of the end faces 28 of a cut-away portion of its hub and a key 29 on its shaft. Its hub also carries a projection 27. This projection is struck by one of the teeth 26, on a disc 25 rigid with the disc 18, if the member 20 needs accelerating into proper timed relation with the disc 18. In another embodiment the sprocket is mounted on a shaft carrying a maltese cross and driven through a spring. The shaft carrying the striker pin and locking disc of the maltese cross is driven through a lost motion device. The locking disc functions in the normal way, but as soon as the striker pin reaches the driving position the lost motion allows the energy in the spring to take charge and rotate the sprocket and striker pin rapidly.
