Abstract: 158,322. Vessot, C. H., Vessot, C. U., and Pilkey, G. A. Oct. 29, 1919. Flax - pulling machines.-The pulling- belts of a flax harvesting machine are driven through depending shafts connected to a transverse driving-shaft by driving-connections which permit the depending shafts to rock slightly. The pulling - belts a r e mounted in double and single frames comprising upper and lower angle-irons 19, 20, connected to shares or dividers 21. The flax is delivered to the pulling-belts 29 by toothed belts 26 driven by leather-covered pulleys 24 on the shafts of the large end rollers carrying the belts 29. The coacting faces of adjacent pulling-belts are pressed together by spring-mounted rollers 30 which are divided into two sets for each belt. Both sets are positively driven from a large roller 36 mounted on a depending shaft 37 and provided with two sprockets 38, 39 for the driving-chains 40, 44 which are covered by the pulling-belt and are provided with tighteners 43. The uppermost roller for each belt is not driven by the chain but is adjustable for tensioning the belt. Each shaft 37 fits into a square hole in a bevel-wheel 51 gearing with a bevel-wheel 55 on the transverse shaft 18. Integral with the bevel-wheel 51 is a sleeve 52 having a conical bore. This sleeve is rotatably mounted in a flanged bearing 53 bolted to the machine frame 10 and fitting into a casing on the angle-iron 20, in which it is secured by setscrews. This arrangement allows of each pulling- elment being removed as a separate unit.

Title: Improvements in or relating to gas turbine installations
IPC: F02C3/28
Filed: 1951-11-15
Abstract: 713,553. Gas turbine plant. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES. Nov. 15, 1951 [Nov. 16,1950], No. 26820/51. Class 110(3) [Also in Group XII] A gas turbine plant fed with gaseous fuel from a liquid cooled gas generator using solid fuels, has the gas generator supplied with gasifying air taken from the circuit of the gas turbine plant bv a compressor driven by a turbine actuated by vapour from the generator cooling system and means for automatically varying the supply of vapour to this turbine in accordance with the load on the output shaft of the gas turbine. The gas turbine plant comprises compressors 1, 2 arranged in series which supply air to the combustion chamber 10 feeding gas to the turbines 4, 5 driving the compressors. The turbine 5 drives an output generator 6. An intercooler 3 is arranged between the compressors 1 and 2 and a reheat combustion chamber 11 between the turbines 4. 5. Gaseous fuel is supplied to the combustion chambers 10, 11 by a gas generator comprising a reaction chamber 12, a cooling jacket 13 to which is connected an equalising vessel 14. a coal charger 15, an ash or slag receiver 16 and a washing tower 17. The fuel gas from the generator is passed through a pressure transformer 18 and then further heated in the slag receiver 16 before being expanded down to the pressure of the combustion chambers 10, 11 in turbines 19, 20. The gasification air for the gas generator is taken from the discharge of the compressor 2 and further compressed in a compressor 21 driven by the turbines 19, 20. An intercooler may be arranged between the compressors 2, 21. Steam from the vessel 14 is supplied to a turbine 27 which assists the turbines 19, 20 to drive the compressor 21. Changes of load cause the governor 7 to actuate the fuel gas throttle valves 23. 24 to vary the fuel supply which results in a change of pressure in the pressure transformer 18. This change of pressure causes a larger change of pressure in the space below the transformer piston 26 which is connected to the equalising vessel 14. These changes of pressure cause automatic variation of the steam supply to the turbine 27. This effect may be amplified by connecting the governor 7 to a throttle valve 28 in the steam pipe leading to the turbine 27 and to a throttle valve 30 controlling a heating means 29 arranged below the accumulator 18. The feed water to the cooling jacket 13 may be preheated by the exhaust gases of the turbine 5, by the hot waste water of the washing tower 17 and by a heater burning tar separated out in the tower 17 or waste gas from the coal charging device 15. The fuel gas may pass direct to the combustion chambers 10. 11 from the generator in which case the compressor 21 is only driven by the steam turbine 27 and an electric motor. The electric motor may be used for starting. The exhaust steam from the turbine 27 may be used to cool the blade rims of the initial stages of the gas turbine 4 and additional output may be obtained by expanding steam with the combustion gases.

Title: Improvements in devices for checking the accuracy of watches, clocks and like timepieces
Inventor: BEVAN NOEL THOMAS JUSTIN
IPC: G04D7/12
Filed: 1961-07-26
Abstract: 1,033,824. Testing timepieces. ALTAIR ELECTRONICS Ltd. Oct. 26, 1962 [July 26, 1961], No.27120/61. Heading G3T. A device for checking the accuracy of a timepiece comprises a mechanical resonator, means responsive to the tick of the timepiece to apply a a series of impulses to the resonator at a frequency equal to the tick frequency or a sub-harmonic thereof, and means for determining the amplitude of vibration set up in the resonator. A piezoelectric transducer 10 or microphone, Fig. 1 (not shown) converts the ticking, e.g. at 1/ 5  sec. intervals, into a signal applied to an amplifier 11 such as a three-stage transistor amplifier having variable gain under manual control. The amplified signals A, Fig. 2 (not shown), are applied to the triggering input of a blocking oscillator 12 which has a relaxation time B, Fig. 2, somewhat greater than that between two consecutive ticks at the nominal rate. Thus each alternate signal becomes a short rectangular positive going pulse, e.g. of four milliseconds as at P(G). The negative going overshoot of the pulse is clipped by a germanium diode 13 shunted across the blocking oscillator with a resistor 14, the resultant output being fed to a solenoid 15 which excites a mechanical resonator or reed 17 resonant at 30 c/s. Co-operating with the reed is an inductance 18 in the circuit of a transistor oscillator 19 arranged to generate an output frequency which is high compared with the resonator frequency, e.g. 50 Ko/sec,and so that this output is modulated at the reed frequency to a depth dependent on the amplitude of the reed. The modulated oscillation is fed through demodulating and filtering means 20 to extract the reed frequency component which is applied to a frequency selective amplifier 21 tuned to 30 c/s, the output being fed to a visual indicator or A.C. pointer type instrument 22. A discriminator circuit may be provided in the output from the demodulator 20 to identify the sign of the error of the timepiece. This error is corrected by adjusting the timepiece regulator until the resonator amplitude is maintained at a steady value for a few seconds. The device will cope with the usual tick frequencies of 2, 4, 5, or 6 per sec. which are sub-harmonics of the reed frequency, provided that the reed has a decrement value of several seconds.
