Title: Improvements in or relating to the polymerization of butadiene
IPC: C08F136/06
Filed: 1965-04-07
Abstract: Lithium (lithio) thiophenolates of the formula <FORM:1032875/C2/1> where a  is 1 or 2, R is a saturated aliphatic or cycloaliphatic radical in which the total number of carbon atoms in R does not exceed 6, and x is 0, 1, 2, or 3, are made by reacting an organometallic lithium compound with a halogenated thiophenol. Similar products are also obtained by reacting an alkyllithium compound with a halogenated benzyl mercaptan of the formula <FORM:1032875/C2/2> where R, a and x are as defined above and X is halogen.  The Specification contains extensive lists of thiophenolates, and benzyl mercaptans. In Example I, lithium (4-lithio) thiophenolate, is made by reacting in toluene 4-chlorothiophenol and n-butyllithium, and in Example IV, 4-chlorobenzyl mercaptan is reacted in toluene with n-butyllithium.ALSO:A polymerization catalyst composition formed by the interaction of an organolithium compound which is a lithium derivative of a halogenated mercapto-aromatic compound and an organotin compound in which a single tetravalent tin atom is bonded to at least one "allylic-type" organic radical and any remaining valencies are satisfied with aromatic radicals.  By "allylic-type" organic radical is meant an unsaturated organic radical in which the double bond is one carbon atom removed from the tin atom.  The organolithium compound may be (1) a lithium (lithio) thiophenolate of the formula <FORM:1032875/C3/1> where a is an integer of 1 or 2, R is a saturated aliphatic or cycloaliphatic radical, and x is 0, 1, 2 or 3, or (2) the reaction product of an alkyllithium with a halogenated benzyl mercaptan of the formula <FORM:1032875/C3/2> wherein R, a and x are as above, and X is a halogen.  The Specification contains extensive lists of catalyst components. Exemplified catalysts are lithium (4-lithio) thiophenolate (prepared by reacting n-butyllithium with 4-chlorothiophenol) and tetraallyltin, the reaction product of n-butyl-lithium and 4-chlorobenzyl mercaptan and tetraallyltin, the reaction product of n-butyl lithium and 4-chlorobenzyl mercaptan and diallyldiphenyltin, and the reaction product of butyllithium and 4-chlorobenzyl mercaptan and allyltriphenyltin.  The catalyst is used to polymerize butadiene, and it may be preformed, or formed in situ. The polymerization is effected in a hydrocarbon diluent, and the reaction terminated by the addition of an isopropyl alcohol solution of 2,21 - methylene - bis - (4 - methyl - 6 - tert -butylphenol.  The polybutadiene may be vulcanized using conventional mixes.

Title: Disc brake in particular for crane driving mechanisms
IPC: F16D55/224
Filed: 1975-04-11
Abstract: 1473464 Wear adjusting in disc brakes FRIED KRUPP GmbH 11 April 1975 [13 April 1974] 15050/75 Heading F2E In a disc brake of the type in which the pads 9, 10 are carried by levers 3 having parallel pivots 4 and applied by springs 29 acting on the free ends of the levers, the brake is released by a device 43 acting through link 46 and with lostmotion 48 on a control lever 33 the latter being connected by linkage 56, 53 having relative lostmotion a to free-wheel devices for adjusting the brake pads. The arrangement is such that during brake application lever 33 is rotated anticlockwise, any lining wear reducing the degree of lost-motion 48, and movement of linkage 56, 53 merely causes devices 50 to free-wheel. On subsequent brake release devices 50 are rotated to screw the brake pads towards the disc to the extent that the anti-clockwise rotation of lever 33 has exceeded a. Lever 33 is pivoted on a rod 23, about which the brake applying springs are mounted, and has a tapered nose portion 36 engaging between rollers 37 for urging the levers apart. The pads are pivotally mounted on members 14 and are relieved of circumferential braking forces by struts 59 acting between the pad pivots and pivots 4 of the brake levers. The struts incorporate resilient mountings for maintaining the pads parallel to the disc when the brake is released.

Title: Continuous stationery assemblies
IPC: B65H39/16
Filed: 1964-04-13
Abstract: 1,049,223. Record web assemblies. G. W. GIFFORD. Feb. 18, 1965 [April 13, 1964], No. 15073/64. Heading B6A and B6F. A group of record webs which are fed at high speed through a computer printer are held together in alignment by tongues punched from the webs and shaped to interlock, the tongues being displaced somewhat from the respective webs and extending through the apertures vacated by tongues of adjacent webs being out of alignment with each other. The group of webs is led into an aperture forming machine by pin-feed tapes 12, Fig. 2 (not shown), and at a roller 14 is turned backwardly about 135 degrees to a roller 16 where the webs are turned a further 360 degrees. Thence the webs pass through a pair of punch and die rollers 23, 24 and by means of rollers 17, 18, 19 and 20 are turned back until they finally emerge on the same path as originally. The extra distance travelled by the outer webs as they are turned by the rollers 14, 16, causes the webs to come out of alignment so the apertures can be punched. The reverse turning caused by rollers 17, 18, 19 and 20 realigns the webs but with the apertures displaced. The amount of displacement can be adjusted, e.g. for various numbers or thickness of webs, by swivelling the carrier 27 supporting the punch and die rollers 23, 24 and a guide roller 29. There may be a pair of punch and die rollers, transversely adjustable, for perforating the other margin.

Patent GB-673290-A (GB)
Title: Process for the preparation of ketocholanic acids
IPC: C07J75/00
Filed: 1950-06-21
Abstract: Ketocholanic acids are manufactured by dispersing a hydroxycholanic acid in an aqueous medium containing a quantity of acetone (e.g. 15-35 per cent by weight) sufficient to dissolve only a portion of the hydroxycholanic acid, and mixing the dispersion with a proportion of a water-soluble oxidizing agent greater than that required for reaction with the hydroxycholanic acid which is in solution.  The preferred oxidizing agent is chromic acid, which may be liberated in situ from a water-soluble chromate salt (e.g. sodium dichromate) and an acidifying agent present in the aqueous medium (e.g. 15-25 per cent of sulphuric acid).  The oxidation is preferably carried out at 28-37 DEG  C., which necessitates cooling or preferably careful regulation of the rate of addition of the oxidizing agent.  Examples describe the oxidation of cholic acid to dehydrocholic acid. Additional starting materials specified are cholalic acid, desoxycholic acids and lithocholic acids.  Specification 582,772 is referred to.

Title: Cloth folding and conveying apparatus
IPC: D06B17/02
Filed: 1963-04-19
Abstract: 968,488. Treating textiles; folding apparatus. KYOTO KIKAI KABUSHIKI KAISHA. April 19, 1963 [April 19, 1962], No. 15543/63. Headings D1L and D1S. A cloth folding and conveying apparatus comprises a roller conveyer arranged arcuately in a treating chamber and means by which cloth is fed to the conveyer, the said means being arranged to fold the cloth in both a horizontal and a vertical sense, the vertical folds being deeper towards that side of the horizontal folds adjacent to the roller conveyer. In the arrangement shown treating chamber 1 contains an arcuately arranged roller conveyer 2, two vertical guide plates 3 and 3<SP>1</SP> provided at the cloth inlet end of conveyer 2, guide rolls 4 and 5, a cloth folding wince roll 6, a rotary shaft 7 and a swinging lever 8 fixed to shaft 7 and rotatably secured to the rotary shaft 6<SP>1</SP> of the wince roll 6. The shaft 6<SP>1</SP> is driven by belt 12 from pulley 10 which is connected to another pulley 11 driven by belt 14 from driving wheel 13. A heart shaped cam 15 is mounted on shaft 16 driven from a driving wheel 18 and controls guide roller 21 of a swinging guide lever 20 fixed at its lower end to shaft 7. In operation rotation of cam 15 causes the wince roll 6 to be swung right and left as indicated by the arrows Y, Y<SP>1</SP> through the action of the swinging guide lever 20, shaft 7 and swing- ing lever 8. The profile of cam 15 is such that the wince roller 6 will travel further from its midpoint in the direction of arrow Y<SP>1</SP> than in the direction of arrow Y. The time taken by the wince in swinging in either direction is however the same and since the cloth feed rate is constant the same length of cloth is folded in a shorter distance in direction Y than in the opposite direction and hence the folds are deeper on the outer periphery t than on the inner periphery t<SP>1</SP> of the folded cloth. The folded cloth is then fed on to conveyer 2 and is led out of the chamber over guide roll 5. In a second embodiment the guide plates 3, 3<SP>1</SP> are swung to left and right by cam 15, the wince roller 6 remaining stationary. .

Filed: 1944-08-16
Abstract: 581,646. Machinery guards. FINE COTTON SPINNERS' & DOUBLERS' ASSOCIATION, Ltd., and BUNTING, J. T. Aug. 16, 1944, No. 15604. [Class 80 (iv)] The guard 7, Fig. 1, of a cotton combing machine is carried on arms 8 which are locked in the closed position when the machine is running by an arm A mounted on a rod B. The arm A has a cam surface a, Fig.. 7, engaged by the edge c<3>, Fig. 6, of a plate C, pivoted on a shaft c', and the edge c<2> of which is in turn engaged by a cam d, Fig. 5, on a lever D secured to the rod B. A quadrant E on the rod B is arranged adjacent the end of a bar G attached to the belt fork 6, the arrangement being such that when the belt is on the fast pulley, the rod B carrying the quadrant E cannot be turned; thus the guard 7 is locked in position. When the bar G is moved to put the belt on the loose pulley, the rod B may be turned by lever D and the plate C allowed to pivot under its own weight, thus freeing the arm A and permitting raising of the guard 7, which is then held in its raised position by a hook M, pivoted to the arm &, engaging the boss of the locking arm A. At the same time the quadrant E on the rod B is. moved into the path of bar G and prevents the belt being put on to the fast pulley. A supplementary device prevents the guard being opened until the moving parts of the machine have actually come to rest. An arm H, connected by links h, h<1> to an extension e<1> on the quadrant E,. has a slot h<2> adapted to engage a fixed stop i on. the frame of the machine. A pawl K is pivoted on the arm H and is adapted to engage a toothed wheel K<1> mounted on a rotating shaft 4 of the machine. When rod B is turned slightly so as to release the guard, while the moving parts are still rotating, the pawl K is moved forward by the arm H and the slot h<2> engages the stop i to prevent further movement, since the pawl K is merely oscillated by wheel K'. When wheel K<1> is at rest, however, if rod B be rotated, the pawl K engages the stationary wheel K<1> and acts as a fulcrum for the lever H, which therefore lifts slot h<2> rises over the stop i to permit further rotation of rod B to completely release the locking arm A, so that the guard may be raised.
