Title: Improvements in machines for manufacturing netting with square meshes
IPC: D04G1/00
Filed: 1924-01-21
Abstract: 231,962. Sereville, L. de. Jan. 21, 1924. Net-making machines.-The knots of square - meshed netting are tightened in the direction of the weft by the application of pressure, to the weft at the moment of releasing the knots, which are thus tightened in both directions in the machine. The warp bar 28 is partially divided by parallel slits 28<1> and each division is perforated for the reception of a warp 1. A pusher 27 slidably mounted in each slit is notched at 42 to engage the weft between the knots. The pushers are mounted on a bar 27<1> maintained in place below the warp bar 28 by clips 29 which also act as stops. The bar 28 and the pushers are reciprocated at the proper times by cam action. The warp roller is fixed to a shaft 3 carrying a brake drum 26 and is reciprocated by a cam 6 acting through a lever 5, adjustable rod 4 and an arm 10, the hub 11 of which is loose on a sleeve 8 fixed to the shaft 3. The hub 11 has two notches 12 engaged by plates 13 the recesses 15 of which rest on the rim 9 of a disc 7 forming part of the sleeve 8. The warp roller is fed forward by the action of the cam 6 while the brahe 23 is removed and the plates 13 are wedged on the rim 9. The plates are released by the action of a cam 20 on a lever 19, a connecting rod 18 and an arm 17 forming part of a sleeve 16 carrying lugs 21. Stops 22 in the lugs contact with and release the plates 13 on the upward movement of the arm 10.

Title: Improvements relating to rectifier apparatus
Inventor: PERSSON JACK
IPC: H02M7/162
Filed: 1962-01-19
Abstract: 974,276. Rectifying. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Dec. 21, 1962 [Jan. 19, 1962], No. 2062/62. Heading H2F. [Also in Division G3] The output voltage of a rectifier apparatus is maintained constant by arranging that the output voltage of a main rectifier is boosted by the output voltage of a second rectifier the supply to which is regulated by controllable rectifiers, e.g. ignitrons, thyratrons, or semi-conductor controlled rectifiers, in dependence upon variations in the output voltage of the apparatus. As shown, a direct voltage at output terminals 2, 3 is derived from a main rectifier bridge D1 to D6 in series with a second rectifier bridge D7 to D12. A three-phase supply 1 feeds the main bridge over a transformer T1 and the second bridge over controllable rectifiers TS1, TS2, TS3 and a transformer T2. The conduction of the controllable rectifiers is regulated by a driver circuit 5 and a controller 4 in dependence upon variations in the output voltage at terminals 2, 3 as detected by a potentiometer R, the arrangement being such that any fall in output voltage caused, for example, by increased load current or a fall in the main rectifier voltage, is counteracted by a corresponding increase in the output voltage of the second rectifier, whereby the output voltage at terminals 2, 3 is maintained at a predetermined value.

Title: Polymerization of diolefines
Inventor: KIBLER RICHARD WINFIELD
IPC: C08F36/04
Filed: 1957-01-24
Abstract: Conjugated diolefines are polymerised or copolymerised with a copolymerisable unsaturated compound in the presence of a dihydrocarbon substituted lithium amide of the formula <FORM:0841691/IV(a)/1> where R is a hydrocarbon radical (see Group IV(b)).  Specified dienes are butadiene, iso rene, 2-methyl-1, 3-pentadiene, 2, 3-dimethyl butadiene and cyclopentadiene and they may be copolymerised with each other or with minor proportions, preferably less than 25 per cent by weight based on total monomers, of styrene or a -methyl styrene.  The monomers hould be of at least 90 mole per cent purity and are preferably purified by refluxing with sodium sand and distilling.  Non-polar, non-acidic organic solvents may be present such as propane, pentane, hexane, heptane, dodecane, petroleum ether, cyclopentane, cyclohexane, and methyl cyclohexane. Metallic lithium or lithium hydrocarbons may also be present with the catalyst which is preferably used in an amount to contain 0,001 to 1,0 gram of lithium element present in the lithium amide for each 100 grams of monomer.  The monomer and solvent are preferably introduced under an inert gas such as helium or argon and may be given a final purification by passing through a silica gel column.  Any oxygen may be purged from the system by evaporating a portion of the charge and sealing.  The catalyst is then introduced and the reaction carried out at 0-150 DEG C. for 3-60 hours.  A methanol, isopropanol or acetone solution of an antioxidant such as mercapto-benzimidazole is added; the alcohol also destroys the catalyst.  If the reaction is carried out in a solvent the product may be introduced into water at a temperature above the boiling point of the solvent which flashes off leaving the polymer as a crumb.  In an example isoprene is p lymerised in the presence of diphenyl lithium amide in petroleum ether.ALSO:Dihydrocarbon substituted lithium amides of the formula <FORM:0841691/IV(b)/1> where R is a hydrocarbon radical are prepared by reacting a lithium hydrocarbon with an appropriate secondary amine <FORM:0841691/IV(b)/2> The two R groups need not be the same and each may be a hydrocarbon group containing 1 to 40 carbon atoms such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, t-butyl, the various pentyl groups, n-hexyl, cyclohexyl, 2-ethylhexyl, nonyl, decyl, undecyl, dodecyl, mixed radicals derived by reduction of the fatty acid radicals of coconut oil or tallow, hexadecyl, octadecyl, eicosyl, heneicosyl, phenyl, benzyl, phenylethyl, the various tolyl, xylyl and xenyl groups and alpha- and betanaphthyl.  The reaction may be carried out at room temperature or slightly above. In an example diphenyl lithium amide is prepared by reacting pentyl lithium with diphenylamine in pentane at 18 DEG  C. for 6 hours.  The product is a dark purple suspension.
