Title: Improvements in or relating to automatic frequency stabilisation of electric oscillators
IPC: B60C7/00
Filed: 1952-10-14
Abstract: 712,584. Automatic frequency control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 14, 1952 [Oct, 17, 1951], No. 25733/52. Class 38(4) A tunable oscillator 5, which may be the local oscillator of a superheterodyne radio receiver, is stabilized at a frequency lying midway between any successive pair of harmonic components of a stable pulse source 15 by mixing the pulses with the oscillator output in a mixer 17 to produce beats. The beats of lowest frequency are taken from the mixer 17 to a further mixer 22 the output of which constitutes a control voltage for correcting the frequency of the oscillator 5. The oscillator 5 is first click-tuned to a frequency. say 23.5 mc/s. approximately midway between the 23rd and 24th harmonic components of the stable 1 mc/s pulse source 1. The pulses are applied in positive sense to the negative control grid of a pentode valve 17 to allow current to pass only during each pulse. The oscillator output is applied to the suppresser grid, and the anode circuit includes a resistance-condenser network 19, 20 which offers substantial impedance only to beats of the lowest frequency, say in the neighbourhood of 0.5 mc/s caused by the oscillator beating with the 23rd and 24th harmonic components of the pulses. If the click-timing of the oscillator has in fact tuned it to 23.48 mc/s. the respective beats are of frequencies 0.48 mc/s and 0.52 mc/s, and when these are mixed in the diode mixer 22, a comparatively lowfrequency beat of 0.04 mc/s appears at the output and is fed through a filter 24 to a reactance valve or like device 13 to frequency-modulate the oscillator 5. As the oscillator frequency reaches its correct value, the low-frequency beat disappears, and the mixer 22 supplies a D.C. voltage across its load resistor 23 to maintain proper frequency and phase relation. The network 19, 20 may be replaced by a circuit tuned to half the pulse recurrence frequency, or to an odd multiple thereof.

Title: Improvements relating to multi-cylinder two stroke internal combustion engines particularly those supplying exhaust gases to turbines
IPC: F02B3/06
Filed: 1946-08-28
Abstract: 616,112. Admission and exhaust pipes; combustion product plant. RICARDO, H. R. Aug. 28, 1946, No. 25738. [Classes 7 (i) and 7 (ii)] In a multi-cylinder two-stroke internalcombustion engine, particularly for supplying exhaust gases to a turbine and having an exhaust manifold comprising a plurality of tubular sections each connected to a cylinder or to the cylinder block and joined to the adjacent tubular section on each of the adjacent tubular sections by a telescopic sliding joint, a scavenging air manifold structure is secured to the cylinders or cylinder block, enclosing the exhaust manifold, and serves to convey the scavenging and charging air to the inlet ports of the cylinders. Each exhaust manifold C is surrounded by an air space F which communicates with the inlet manifold E by means of openings G<1> in a partition G, which latter acts as a heat deflector and thereby reduces the heat transfer from the exhaust manifold C to the supercharging air in the inlet manifold E. Dilution of the exhaust gases may be effected by leakage of air, which is under higher pressure than the exhaust gases, from the space F either through the telescopic sliding joints in the exhaust manifold, or passages provided therein. This may be convenient when the exhaust gases are used to drive a turbine.

Title: Improved process for extracting sulphur from sulphurous masses, particularly gas cleaning masses
IPC: C01B17/033
Filed: 1950-10-26
Abstract: <PICT:0694875/III/1> In the extraction of sulphur from masses containing it, particularly gas purifying masses, by treatment with sulphur solvents, particularly carbon disulphide, the residual solvent remaining in the mass is removed by the passage of superheated vapours of the solvent itself through the mass.  In the Figure sulphur-containing masses are contained in an inner vessel c spaced from an outer double walled vessel b through which double walls heated steam may be passed.  The upper part of the vessel c is provided with a coke filter e, sealing being effected by a coverplate g and water seal h.  The solvent enters through pipe i and passes down between the heated inner wall a of vessel b and that of container c and thus heated, enters through the perforated plate f into the sulphur-containing mass.  The sulphur laden solvent then passes to a distilling vessel k, the sulphur being deposited and the solvent vapour passing partly to the condenser l and partly to the extraction vessel through pipe p.  When the mass is freed from sulphur, solvent is withdrawn from vessel c to a container n through pipe o.  Solvent vapours from k are now passed in through pipe p and, superheated by the hot inner wall a, remove the remaining solvent in vessel c.  The vapours are exhausted by a jet c of liquid solvent and return via a cooler u to the solvent storage vessel n.  A final flushing with steam removes the solvent vapours.  Several extraction vessels may be arranged in parallel or, preferably, in series.

Abstract: 1316804 Winding webs EASTMAN KODAK CO 2 June 1970 [2 June 1969] 26560/70 Heading B8R Apparatus for winding a web or webs to a prescribed roll tightness comprises a plurality of slip clutches each having an output member of a larger radial dimension than the corresponding driven input members, the clutches being disposed on a shaft so that respective tandem combinations thereof may wind about their output members webs of corresponding widths; control means co-operaitve with the clutches for adjusting the coupling between the input and output members thereof; and means for producing a control signal or signals proportional to the radius of a roll or rolls being wound. With this arrangement the clutches co-operate in groups to provide wind-up torque commensurate with the widths of respective webs being wound. As shown, a wide web 10 is peeled from a supply roll 12 and is slit by cutters 14 into alternate narrow webs 18, 20, 22, 24, 26 which may be of any selected width and which are wound by respective drives 28, 30 each including a motor 32 or 38 driving a shaft 34 or 40 to which a plurality of electromagnetic clutches 36 or 42 are ganged. A control device 60, in response to a signal proportional to the radius of a roll being wound, increases the electrical power supplied as the torque requirements of a clutch increase, and a speed control device 62 operates to decrease the speed of the drive shaft gradually as the radius of the rewind roll increases. Thus a narrow rewind web such as 18 which is half as wide as another such as 20 is wound on, and by, half as many clutches as the wider rewind web, but since the rewind rolls in question similarly grow in radius, their respective clutch couplings are simultaneously similarly increased during rewinding. A computer arrangement for deriving the speed and slip-coupling control signals, and a suitable form of clutch are described with reference to Figs. 2 and 4 (not shown).
