Abstract: 622,359. Agricultural implements. GIRLING, A. H. G. Aug. 17, 1946, No. 27603/47. Divided out of 622,278. [Class 6(i)] [Also in Group XXXI] In walk-type tractor power is transmitted from the engine to the driving wheel or wheels through a clutch having driving and driven sections which tend to assume the disengaged position and engagement of which, is effected by operation of a twistgrip control associated with the steering handle. The same twist-grip control may be-used to operate an agricultural implement such as a hoe..The power unit 10, which may be a governor, - controlled internal combustion engine transmits the drive through clutch housing 22 to the driving wheel 11. The clutch housing 22, Fig. 4, includes a cone clutch whose two halves 12a, 12b, are normally kept separated by the compression spring 19. The clutch is engaged by rotation of the twist grip 252, Fig. 1, which moves the chain 26, bell-crank lever 24, rod 21 and so rotates the segment 201 whereby balls 23 held in recesses between the segment 201 and the casing cause axial displacement of the segment and of the clutch member 12a. The other'end of the chain 26 is attached to a second bellcrank lever 28 which actuates rod 29 to vary the height of the wheel 16 and hence the working depth of the hoe; the wheel 16 being mounted at one end of a centrally pivoted lever 15 the other end of which is quadrant-shaped and notched, the lever being locked in the desired position by a detent 171 on a lever 17 which is operable by rod 29. Specification 622,358 is referred to.

Title: Recovery of iodine
Inventor: WOOD PETER WORSLEY SPENCER
IPC: C01B7/14
Filed: 1964-07-08
Abstract: Iodine is eluted from anion-exchange resins containing it by using aqueous NaOH solution as eluent, the residual iodine then being removed by elution with aqueous NaCl solution.  The eluate from the elution step with NaCl may be chlorinated and acidified to produce elemental iodine crystals which are removed by filtration; the NaCl-containing filtrate, with or without neutralization with NaOH, is reused for elution of residual iodine.  This filtrate, before being re-used for elution, may be treated with activated carbon to remove dissolved iodine; the activated carbon carrying the removed iodine is contacted with aqueous NaOH to liberate iodine, the iodine-containing solution is neutralized with acid and chlorinated whereby elemental iodine crystallizes out and is separated by filtration.  The anion exchange resin may be a weakly basic resin on a strongly basic quaternary ammonium resin, e.g. "Amberlite" (Trade Mark).

Filed: 1962-07-23
Abstract: Organophosphonous diamides of the general formula R.P(NHR1)2, wherein R is a hydrocarbon radical having at least one electronegative substituent on the nearest possible carbon atom to the phosphorus atom, and R1 is hydrogen, alkyl or aryl, are prepared by reaction of a phosphonous dihalide of Formula RPX2, where in dihalide of Formula RPX2, wherein X is halogen, with ammonia or a primary amine.  R may be alkyl, when the electronegative group is on the carbon attached to the phosphorus, or may be aryl, in which case the said group is on the carbon ortho to the C-P linkage.  The preferred electronegative substituent is fluorine.  The reaction may be performed by simple admixture of the reactants, in a ratio of phosphonous dihalide to amine of from 1:4 to 1:10, at a temperature between - 80 DEG  and + 50 DEG  C., optionally in an inert solvent such as hydrocarbons, ethers, fluoro- and chlorofluoro-carbons.  Examples are given for the preparation of trifluoromethyl phosphonous diamide from the corresponding difluoride, dichloride and diiodide, and of 1,1,2,2-tetrafluorethyl phosphonous diamide.  The diamides may be polymerized by heating to provide heat-resistant polymers (see Division C3).ALSO:Heat stable polymers containing phosphorus and nitrogen are prepared by heating to a temperature above ambient, an organophosphonous diamide, of general formula RP(NHR1)2 wherein R is a hydrocarbon radical having at least one electronegative substituent on the nearest possible carbon to the phosphorus atom, and R1 is hydrogen, alkyl or aryl.  R may be alkyl, in which case the electronegative group is attached to the carbon linked to the phosphorus atom, or may be aryl, when the said group is on the carbon ortho to the carbon-phosphorus linkage; the preferred electro-negative group is fluorine.  Polymerization is suitably effected at a temperature above ambient to 200 DEG C., at sub-atmospheric pressure; either with or without an inert solvent, when ammonia or primary amine is liberated with accompanying formation of the polymer. Alteration of the reaction conditions may alter the composition of the polymer, but a typical empirical formula for a product from a diamide unsubstituted on the nitrogen atom is (R2P2N3)n, where n gives a mol. wt. in excess of 1000.  Examples are given for the preparation of polymers from trifluoromethyl phosphonous diamide under various conditions of temperature and pressure, and from 1,1,2,2-tetrafluoroethyl phosphonous diamide, and also for the preparation of these diamide starting materials (see Division C2).

Filed: 1951-12-01
Abstract: 709,758. Automatic volume control. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Nov. 10, 1952 [Dec. 1, 1951], No. 28220/51. Class 40 (4) In a pilot-controlled carrier current transmission system, changes in the level of the pilot change the voltage distribution across a potential divider, the output from which is amplified and applied to change the voltage distribution across a second potential divider having a fixed tapping connected to the input of a line amplifier to vary the overall repeater gain in accordance with the changes in pilot level. In the system employing two pilots for flat gain and slope control, Fig. 1, the flat gain pilot selected by a band pass filter PFF is applied via potential dividers comprising a directly heated thermistor TH1 and resistor R1 and thermistor TH2 and resistor R2, and rectifiers MR1 and MR2 to the grids of valves VI and V2 respectively. Heaters of thermistors TH3 and TH4 in the potential divider associated with the line amplifier input circuit form, with a common resistor R3, cathode loads for valves V1 and V2 respectively so that the arrangement of thermistors TH1 and TH2 and the valve circuits give a push-pull effect as far as overall compensation by the input potential divider is concerned. The resistances of thermistors TH1 and TH2 are very large compared with R1 and R2 and the arrangement results in potentials Ea, Eb, as shown in Fig. 2, Ec being the pilot voltage. The intersection of the curves is the normal working point and results in a constant pilot output over a wide range of variation of pilot input, and a steady value of stage gain within the working range in the event of pilot failure. A modification in which the flat control unit FCU is dispensed with and the second potential divider is connected across the line is also described. Slope control by the pilot signal selected by filter PFS is similarly achieved.
