Title: An improved method and means for advancing and retarding a driven shaft relatively to a driving shaft
IPC: F02P5/155
Filed: 1924-04-10
Abstract: 236,657. Constantinesco, G. April 10, 1924. Fire between aircraft propeller blades, controlling and synchronizing. - Centrifugally-operated pawls on a driving shaft, engaging notches in a driven shaft, are employed to effect one or more stages of lost motion, and thus to vary the phase relation between the shafts at one or more definite speeds of rotation. The invention may be applied to cams for operating synchronizing gears controlling fire of aeroplane machine guns. A pawl 2 carried in a rotating driving-member 1 is provided with two projections 4, 7, one 4 of which engages a notch on the driven member 5 under the action of a spring 3 at low speeds. At a predetermined higher speed, the pawl is thrown outwards, the notch is disengaged and the member 1 moves in advance of the member 5 until the projection 7 strikes the notch and resumes the drive. To secure a smaller advance of a driven shaft, the members 1, 5 may be geared up from the driving and driven shafts. In the modification shown in Fig. 3, pawls 22, 20 each carry only one projection for engaging the notch on the driven member 29, but the pawl 22 also carries a projection 25<1> for engaging a lug on the pawl 20, and the latter carries a projection 33 for engaging a lug on a third pawl 24, which carries two projections 34, 35 for engaging the notch. Springs 27 of graded strengths tend to engage the projections 25, 32, 34 with the notch. The weak spring 27 first connects the projection 25 with the notch, the remaining pawls being locked by the interengaging projections. At the predetermined speed, the pawl 22 swings outwards and releases the pawl 20, of which the projection 32 is brought into the path of the notch, so that the shaft 29 is relatively retarded for nearly a revolution before the drive is resumed. At a further increase of speed, the pawl 20 lifts and releases the pawl 24, so that after further relative rotation of the parts, the projection 34 engages the notch. As a final stage, the strong spring controlling the pawl 24 is overcome and the projection 35 engages the notch. The projection 35 may be dispensed with so that the driving member is finally completely disengaged from the driven shaft 29. Two or more notches may be provided on the driven member, so modifying the extent of the lost motion between the parts. The driven member may be moved axially in relation to the driving member in order that complete disengagement between the members may be effected, or, as shown in Fig. 1, the driven member 5 may be movable axially by operating means 11, 12 into a.nd out of clutching engagement with a sleeve 14 secured to a sleeve a which may carry a cam operating a wire d acting on the trigger of an aeroplane machine gun. According to the Provisional Specification, the angles of the notches and projections may be so formed that the parts slip over each other at low speeds, so as to stop the drive. Specification 236,686 is referred to.

Abstract: 1474511 Fuel elements; control elements COMMISSARIAT A L'ENERGIE ATOMIQUE 6 March 1975 [28 March 1974] 9395/75 Heading G6C A device for supporting a cluster of fuel or neutron-absorbent pins 11 within the casing 2 of a fuel or control assembly comprises, at the lower end of the vertically disposed casing 2, a supporting member 6 for a series of parallel rails 15 with ribs 14 on their upper extremities which are slidably engaged in grooves 13 formed in the end caps 12 of the pins 11. The supporting member 6 has vertical parallel slots 16 in which are engaged the lateral extremities of the rails 15, the rails being secured by locking means mounted within grooves 9 formed in the sides of the supporting member 6 and through which extend the vertical slots 16, the locking means co-operating with those portions of the rails 15 which pass through the grooves 9 within the vertical slots 16. In the illustrated embodiment, the locking means comprise locking rods 17 engaged within the grooves 9 and penetrating into notches 18 formed in the rails 15 at the level of the grooves 9. In the case, as illustrated, in which the supporting member 6 is mounted within a casing 2 having a hexagonal cross-section, the grooves 9 comprise two diametrically opposite grooves 9a, 9b each extending along two consecutive sides of the cross-sectional hexagon. The spacing of the pins in each row is ensured by means of a wire 11a helically wound on the external surface of the cam of each pin 11. Positional locking of the rails 18 is completed by a comb 19 mounted within a recess 20 formed in the supporting member 6 and extending at right angles to the plane of the rails 15 so that the slots 21 formed between the teeth of the comb are traversed by the rails. In alternative embodiments, suitable spacing of the pins 11 from one row to the other is ensured, not at the level of the rails 15, but at the level of the pins themselves. This may be effected, as described in Specification 1,474,321, by displacing the points of attachment of the wires 11a to the end caps 12 by 60 degrees with respect to the planes of the grooves 13 or, alternatively, by forming overthicknesses of either cylindrical or prismatic shape on the end caps 12.

IPC: H04L1/04
Filed: 1960-03-17
Abstract: 880,673. Radio receiving systems. STANDARD TELEPHONES & CABLES Ltd. March 17, 1960, No. 9399/60. Class 40(5). In a dual diversity system the two path signals are combined according to the noise received on frequencies adjacent to the modulating frequencies in such proportions that the combined signal has a better signal to noise ratio than either of the two path signals, this ratio being the difference between the level of a given test signal applied at the transmitter and the level of noise in the demodulated signal, measured at an appropriate point in the receiver. In the embodiment described the path signals are applied to receivers 2A, 2B, Fig. 2, and thence through low pass filters 4A, 4B and variable attenuators 5A, 5B to a combining circuit 6 and output circuits 7. Noise on adjacent frequencies is fed via bandpass filters 3A, 3B to noise level equalizing networks 8A, 8B, and thence to a combiner 11. A known A.V.C. device 13 controls the gain of amplifiers 14A, 14B whose outputs are applied to rectifiers 15A, 15B, and thence to a subtracting network 16, the resultant difference signal being applied to a low pass filter 17 to control the said two variable attenuators 5A, 5B. To compensate for errors due to the combining process, a pilot signal is transmitted and derived by using a local oscillator 18, whose frequency is higher than the modulating frequency band, is applied via a combiner 19 to the outputs of filters 4A and 4B, and thence to output circuits 7 which have A.V.C. applied. In a further embodiment the pilot signal is derived locally by an oscillator 28 (Fig. 4) the signal from which is applied together with the noise signal through a limiter, discriminator and differentiator. The noise phase modulates the local signal. Noise amplitude variations are thus reduced. In a further embodiment rectified noise is fed to a commutator 49, Fig. 5, which reverses the phase of the output from rectifier 47. The commutator is supplied from a local oscillator 50 with a test wave of frequency F above the pass band of filters 3A, 3B. The commutator output is filtered, amplified, and the positive and negative voltages appearing at 54A, 54B are rectified and combined such that either a positive or a negative control voltage adjusts the attenuation of circuits 5A, 5B. The test wave is superimposed on the control voltage by transformer 60.

Title: Improvements in or relating to control devices for hydraulically actuated jacking orparking mechanisms
IPC: B60S9/21
Filed: 1958-03-24
Abstract: 852,124. Jacking motor vehicles. BUTTERWORTH, A. J. March 23, 1959 [March 24, 1958], No. 9433/58. Class 79(3). In a hydraulically operated jacking or parking mechanism wherein a hydraulic ram on each side of a vehicle is connected through a valve mechanism to a pump driven by the vehicle engine, the valve mechanism comprises detent means which are released only when the vehicle is stationary or travelling at slow speed and means are provided for automatically cutting off communication between the ram and the pump when the engine stops. The valve comprises. ports 11, 12, 13 and 14 and spool 29, the port 11 being connected to a fluid reservoir 7 and inlet of the pump 5. The outlet of the pump 5 is connected to port 13 and port 12 is connected to the hydraulic ram cylinders 36. Port 14 is connected to the reservoir 7, through a filter 35. In the position shown in Fig. 1, the pump is energizing the hydraulic ram through 13 and 12, ports 11 and 14 being cut off. Movement of the valve spool to the right, Fig. 3, connects 11 to 12 and 13 to 14 allowing the pump to short circuit through the reservoir. The spool is normally held in the latter position by engagement of a detent 22 with a groove 23. The detent may be retracted by an electromagnet 25 which is energized by a switch which may only be closed when the engine is in a low or reverse gear-dependent upon the position of the change speed lever or selector. When the detent is withdrawn the valve spool is operated manually through a cable connection to the facia panel. The cylindrical portion 19 of the valve spool is smaller than the portions 20 and 21 and when the spool is in the position whereby the pump is operating the ram, the pressure difference due to the differing diameters holds the spool in the operating position against the pressure of a retaining spring 31, in which position it will remain until the engine stops or the spool is manually returned. Sealing rings 33 and 34 are provided. The hydraulic ram mechanism may comprise one or a pair of ground engaging rollers, Figs. 5 and 8, and may comprise a roller 47, Fig. 4, engaging a rim 48 of a driven wheel and through which and a pair of bevel gears, the drive may be transmitted to the ground engaging roller. Specifications 832,679 and 842,331 are referred to.

Abstract: 107,600. Barbet et fils et Cie, E. Oct. 19, 1914, [Convention date]. Addition to 107,599. Multiple-effect apparatus; alcoholic liquids &c., distilling.-The multiple-effect distilling plant of the parent application is modified by the provision of means for degasifying the liquors before distillation and for purifying the resulting phlegms by means of the waste heat from the apparatus. To degasify the liquor, it is passed from the heater C<2> into a heater C<3> receiving vapours generated in the column C, and thereafter is led on to the plates E to which vapours from the column C are also admitted by a valve U. The gases flow to a cooler T. The phlegms formed by condensation of the vapours from the column C in the heater C<3> are led to a phlegm purifier D. The degasified liquor from the plates E is directed partly by a pipe controlled by a valve R<111> to the column C, and partly by a pump P to a heater A<2> receiving vapours generated in the column A. The liquor from the heater A<2> passes under the control of valves R<1>, R<11> to the columns A, B. The column A receives a supply of heat which is regulated as in the parent invention. The exhausted liquor from the column A is led into the column B or its boiler B<1>, and the united liquors are similarly led into the column C or its heater C<1>, the completely united liquors then flowing to the heater C<2>. The uncondensed gases and vapours from the heaters A<2> and boilers B<1>, C<1> are united and led to a heating-coil at the base of the purifier D. The phlegm thus obtained enters the top of the purifier, which also receives the phlegms from the boilers B<1>, C<1>, and that from the cooler T, either directly or by way of the heater C<3>.
