Title: Method and apparatus for tamping railway track
IPC: E01B27/17
Filed: 1971-10-12
Abstract: 1344147 Ballast tamping machines CANRON Ltd - CANRON LIMITEE 12 Oct 1971 [12 Oct 1970] 47509/71 Heading E1G The common, e.g. hydraulic, drive means for the front and rear pairs 11, 12 of tamping heads of a tamper machine 10 adapted to squeeze the ballast beneath respective sleepers is arranged to complete the squeezing phase of one pair of heads, e.g. the front, before commencing the squeezing phase of the other pair so that the peak power demands of the pairs are thereby staggered. The front and rear pairs 11, 12 are simultaneously lowered into the ballast and the front pair perform their squeezing operation until a pressure sensitive switch 15 is operated which withdraws the front pair and initiates the squeezing of the rear pair 12 which continues until a pressure sensitive switch 25 is tripped which withdraws the rear pair. The withdrawal of the rear pair activates a further switch to move the machine foreward until sleeper indexes 19, 20 sense the next sleeper. A track lifting and aligning jack J operates simultaneously with the front tampers 11. The front tampers may be fixed on the machine 10 and the rear tampers movable. The tampers are electrically vibrated.

The  term "plastics material" is defined as a non-metallic dielectric substance capable of undergoing plastics flow, examples being crystalline or amorphous polymers, glasses and mica. The core may include a non-superconductor metal and the superconductor may be an elemental metal, an alloy, or an intermetallic compound. An alloy or compound super-conductor may be initially provided in the form of its components which are reacted together after drawing down the conductor to the desired size. An extrusion-can may be used and may be removed or left in position after the drawing step. The super-conductor material may be Nb 44 wt per cent Ti, Mo 50 atomic per cent Re, V 3 Si, InSb, PbBi, In, PbSn, Sn, CdPb, Pb. Rods of V embedded in silica glass may be heated to react the V with Si from the glass. A Nb tube containing Al powder may be used to produce Nb 3 Al. A core of mixed Nb and Cu powders may be used and when drawn down a sponge like structure of Nb with Cu in the pores is formed. When the core contains a plurality of filaments they may be twisted. Gaps up to 1Á long may be tolerated in the super-conductor filaments.

Title: The preparation of aryl esters of carboxylic acids
IPC: B01J31/04
Filed: 1963-12-09
Abstract: Aryl esters of aliphatic or alicyclic mono or poly-carboxylic acids are made by heating methyl esters of these acids to a temperature above 160 DEG  C. with the appropriate phenol, in the presence of a trans-esterification catalyst, the methanol formed being continuously removed from the reaction mixture.  The phenol is conveniently an alkyl phenol, an aralkyl phenol, an alkyl aralkyl phenol, a naphthol or phenol itself.  The methyl esters are derived from aliphatic or alicyclic mono- or polycarboxylic acids containing up to 20 carbon atoms which may also contain halogen atoms. The catalystsmay be polyphosphoric acids, acid phosphates of alkali metals, hydroxides of alkali metals or alkaline earth metals, or tertiary amines. Preferred catalysts are butyl titanate, tin stearate and fatty acid salts of a metal of Group II of the Periodic Table, e.g. calcium stearate or the zinc salt of the first fraction of coco-fatty acids. Reaction temperatures are generally in the range of 190 DEG  to 250 DEG  C.  An excess of up to 6 mols. of the phenol per equivalent of methyl ester may be used.  Mixed methyl aryl esters may be obtained by using the number of equivalents of the phenol equal to the number of methyl groups to be replaced, or using excess phenol and interrupting the reaction.  Specification 470,937 is referred to.

The shaft 2 of each rotary member 3 (Fig. 3) is rotatably journalled in ball-bearings 4, 8 housed in the harrow's frame 1, and carries a pinion 10 which meshes with the pinion of a neighbouring member 3. A support 11, for a single 5 cm. wide curved strip tool 16, is connected indirectly to shaft 2 via strip 12 and transverse support 15. There are cutting edges on blade 17, fastened to tool 16, and on the free end of tool 16. The tools 16 of neighbouring rotary members 3 are angularly offset by 180‹ about their axis of rotation (Fig. 1) to prevent fouling each other. A ground roller 23 (Fig. 2) acts as a soil compressor and as a harrow support, and its height, adjustable by means 21, 22, 24 determines the depth of penetration of the tool 16. The rotary members 3 are driven from the tractor via a telescopic transmission shaft 28, input shaft 27, change-speed gear 26 and gearbox 25 into which the central pair of rotary members upwardly extends. A triangular coupling member 29 has means 31, 32 at its apex for hitching to the tractor and for adjusting the harrow's angle of tilt. The rotary member 3 may include short tines integrally formed with bolt-heads 13 or may comprise a support 34 and tool 38 and having alternative means for interconnecting the support 34 and shaft 2, wherein a bridge portion 36, or sleeve portion [44] is bolted to a splined portion of shaft 2. The support 34 may, instead, have a square cross-sectioned upward extension for insertion into a bore of matching cross-section in drive shaft [52], to be held by a fastening nut at its top. Thus the support may be detached and replaced by an alternative, e.g. tined rotary member. The tool may be welded to the support, or formed from a single piece of metal, and the support may also bear a perpendicular projection, located higher than the tool, for ensuring enhanced soil aeration.
