The rounded-up lumps may pass down an incline on to a conveyer 68. When it is desired to roll the roundedup lumps into cylindrical rolls, the lumps leaving the spiral member enter the flared pivoted end 78 of a stationary channel member 72, and are passed by the cone along the channel to be discharged down a shoot 76. The table 15 is provided with pockets 19 provided with plungers 20 carrying rollers in engagement with a cam track 23, 24, 25. In operation, when the table-brings an aperture 18 beneath a dough hopper 34 supplied with compressed air from a pipe 36, dough is forced into the corresponding pocket and depresses the plunger 20 which, in turn, depresses a portion 23 of the cam track against the action of springs, and against an adjustable stop operated by a hand wheel 33. The cam portion 23 is connected to the part 25 by a spring member 24. When the pocket has moved from beneath the aperture in the hopper, the roller 22 moves up the cam track, and the plunger 20 comes flush with the table. The ejected dough lump is then carried by the table to the rounding- up channel formed between the stationary spiral 62 and the rotating cone 47.

Abstract: 1,158,443. Determining vehicle wheel unbalance and ignition spark advance angle, electrically. G. DONATO. Feb.28, 1967 [March 5, 1966], No.9342/67. Heading G1N. A combined instrument for vehicle wheel unbalance and ignition advance angle testing using stroboscopic methods, comprises an inductive detector B Fig. 4 responsive to firing of a spark plug, an inductive vibration detector A for attachment to a vehicle body adjacent a wheel to be balanced and having two coils also two magnets on a swinging arm so that vibrations from the vehicle are transmitted to the arm and induce voltages in the coils. Ignition timing. To determine the spark advance angle, detector B is connected to terminal 12 and a selector switch 9 is switched to position 9'. When the plug fires a resulting pulse is shaped and levelled by a circuit including a valve VIa, the output pulse from the cathode of which is fed via line 10 to a thyratron V5 causing it to fire. This in turn lights a stroboscope lamp 4. The engine pulley illuminated thereby will appear stationary and the distance between a notch on the pulley and a datum mark on the engine block indicates the advance angle. To measure this angle in degrees the selector switch is switched to a position 9", thus introducing a time delay circuit, including valves V2a, V2b, V1b which makes it possible to delay the ignition of the strobe lamp 4 with respect to the spark plug firing, by adjustment of a potentiometer 13a b in the said circuit, until alignment of the pulley notch and datum mark is observed. A first scale on a meter 11 will then show the spark advance angle in degrees. Wheel unbalance test. To locate and determine unbalance in a wheel the detector A is connected to terminal 12 and the selector 9 is switched to position 9"'. A reference mark is made on the wheel and the wheel is rotated by the engine or by motor driven rollers. Vibration pulses from the detector A which is applied to the vehicle suspension adjacent the wheel to be balanced, are levelled, shaped and amplified in a circuit 1' including valves V3, V4a, V4b and the amplified pulses are fed to the meter 11 a second scale of which is calibrated to indicate the unbalance vibration magnitude. The amplified pulses are also fed to the thyratron V5 which causes operation of the strobe lamp 4. The lamp will illuminate the reference mark which will appear stationary. The observed position of the mark is noted and the wheel is stopped. The wheel is then rotated slowly until the mark is at the position observed by the strobe flash. A balance weight corresponding in magnitude to that indicated on meter 11 is then fixed to the wheel at a position diametrically opposite to a position adjacent the detector A to correct the unbalance. The power supply circuit includes a full wave rectifier V6 and a voltage stabilizer V7.
