Abstract: 418,300. Variable-speed gearing. FODENS, Ltd., WHITTLE, R. W., and TWEMLOW, E., Elworth Works, Sandbach, Cheshire. March 18, 1933, No. 8232. [Class 80 (ii).] Relates to gearing of the kind comprising constant-mesh gears on main and lay shafts adapted to be operated by clutches all engaging in one direction and provided with chamfered teeth to prevent engagement if the speed of a driven element exceeds that of its driving element. The clutches are engaged by dogs 34-38, Fig. 3, slidable to the left, Fig. 4, by a tappet 46 carried by a rod 47, which is rotated to preselect the desired gear by an arm 48 connected to the gear-lever, and then slid to the left by the clutch-pedal. Each dog, such as 34, carries a slide 45 adapted to contact with the tappet 46 and to urge the dog resiliently towards the clutch engaging position through a compression spring 49 against the action of the weaker disengaging spring 44. The clutch is retained in engagement by a detent 52 engaging a projection 51 on the slide 45. A quadrant 56 is splined on the draw-bar, and initial movement of the engine clutch pedal, acting on the collar 61 moves the quadrant to the left so that its flange 65 trips the tails 55 of all the detents 52 except the one corresponding to the selected clutch, a gap 60 being provided in the flange opposite to the tappet 46. During this disengaging movement the bar 47 is held by one arm 72 of a bell-crank. The other arm, not shown, is then struck by a lug on the engine clutch lever so as to lift the arm 72 and permit movement of bar 47 to engage the selected clutch. Rollers or balls 87, Fig. 3, held in cages 86 so as to engage opposed grooves on the sides of the dogs, contact with pins 89 passing through holes in the dogs, the total length of the rollers and pins being such that when one dog is shot into the engaging position the others are locked.

Abstract: 1,208,273. Yeast &c. BRITISH PETROLEUM CO. Ltd. Feb. 9, 1968 [Feb. 22, 1967], No. 8357/67. Heading C6F. In a process which comprises cultivating in a broth a micro-organism capable of growing on at least some straight chain hydrocarbons, in the presence of a hydrocarbon feedstock which consists at least in part of straight chain hydrocarbons, an aqueous nutrient medium and a gas containing free oxygen, (a) ammonia and (b) a sterilized aqueous nutrient medium which contains a free phosphoric acid, are added to the broth, each either intermittently or continuously. An example is directed to the cultivation of Candida lipolytica on gas oil n-paraffins containing disclosed preparations of C13-C19 hydrocarbons. Ammonia was continuously injected into the culture broth in order to maintain the pH at 5À5. The aqueous nutrient medium fed to the fermenter was continuously sterilized for 2 minutes with steam at 140‹ C. and the inclusion in the nutrient medium of 1À2 grams/litre of orthophosphoric acid considerably reduced the incidence of blockages in the sterilizer. Many species of micro-organism are particularly mentioned.

Abstract: 766,243. Pulse amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 24, 1955 [March 26; 1954], No. 8597/55. Class 40(6) In a circuit having an adjustable phase response characteristic, a current proportional to the input signal is supplied to a network comprising a resistor in parallel with the series connection of a variable resistor and a reactance, the voltage produced in the circuit of the reactance, decreased by a voltage proportional to the current, providing the output signal. A step function is applied to the grid of discharge tube 1 having a resistor 2 in the anode circuit, across which is connected a variable resistor 3 and tuned circuit 4. A resistor 5 of half the value of resistor 2 is arranged in the cathode circuit and feeds a signal to one grid of a mixing tube 6, to the other grid of which is fed the signal from circuit 4. The vector V<SP>5</SP>, Fig. 2, is combined with the vector V<SP>4</SP> to give the output vector V<SP>6</SP>, the vector V<SP>4</SP> passing round the circle c but giving a constant amplitude vector V<SP>6</SP>. The phase characteristic may be adjusted by variation of resistor 3, or the resonance frequency of circuits 4. The reactance 4 may be replaced by the series combination of a number of parallel resonant circuits having equal capacitors (Fig. 4, not shown) the resonant frequencies constituting an arithmetical series. Alternatively, a number of series resonant circuits may be employed (Fig. 5, not shown), all the inductors having equal value.
