Title: Improvements in and relating to thermionic valve relaxation circuits
IPC: H03K3/10
Filed: 1947-03-11
Abstract: 628,409. Pulse generating circuits. GENERAL ELECTRIC CO., Ltd., and BRYDEN, J. E. March 11, 1947, No. 6762. [Class 40 (vi)] In a " flip-flop " circuit the time constant of the grid circuit of the valve which conducts in the unstable state is made longer than that of the grid circuit of the other valve by insertion of a resistor so that the " flip-flop " remains in the unstable state for a relatively long time period, the duration of which can be readily adjusted. The Figure shows a circuit in which in the stable state valves V1 and V2 are respectively non-conducting and conducting. The time constant of the grid circuit of valve V1 is increased by resistor R3 so that it is longer than that of valve V2, thus when a negative going pulse at terminals T3, T4 triggers the " flip-flop " into its unstable state capacitor C2 is only slowly charged up by grid current flow in valve V1 and the duration of the unstable state is determined by the value of resistor GL1 and capacitor C1. Capacitor C3 maintains the frequency response of the grid circuit of valve V1. Diode V3 limits the amplitude of the negative excursion of the pulse applied from the anode of valve V2 when the circuit changes back to its stable condition. The anode circuit of valve V1 may be decoupled by a resistor-capacitor combination having a time constant which is short compared with that of the other networks of the circuit but is long enough to ensure that when the " flip-flop " reverts to its normal stable state, if another triggering pulse is applied the anode potential of valve V1 will be low compared with its potential when the decoupling capacitor is fully charged. Specification 628,406 is referred to.

Title: Improvements in or relating to jet nozzles for jet propulsion purposes
Inventor: BROWN DAVID MORRIS
IPC: F02K1/56
Filed: 1956-03-05
Abstract: 814,136. Jet propelled aircraft. ROLLS-ROYCE Ltd. March 4, 1957 [March 5, 1956], No. 6925/56. Class 4. [Also in Group XXVI] An aircraft jet propulsion nozzle comprises thrust-reversing means having vanes extending at least partly round the nozzle axis, the vanes being adapted, when operative, to deflect the issuing gas to have radial and forward components and also, for at least some of the gas, tangential components, the resultants of the radial thrusts and tangential thrusts each being zero. In Fig. 1, a divergent conical duct 11 is joined to the jet pipe 10 and contains six equally spaced members 13 each composed of two triangular walls 13a joined together at an acute angle along one side 13c and with sides 13d contacting duct 11. Each member 13 is closed by a sector shaped wall 13b (see also Fig. 3) and contains partitions 15. Apertures 16 equalize the pressures on the sides of each wall 13a. Part of the outlet of duct 11 is blanked off by members 13, which leave intermediate sector shaped openings between walls 13b, and the dimensions are such that the available crosssection of the duct decreases in the downstream direction. The sides 13c at their downstream ends each contact a fixed central tube 14 on which is rotatably mounted a sleeve 17 bearing twelve radial plates 18, alternate pairs of which are bridged at their radially outer-ends by arcuate plates 19 (see also Fig. 3). The ducts 40 so formed are open at each end, and in normal use these ducts are aligned with the spaces between adjacent walls 13b, the gas stream passing straight through as shown by arrows 31. For thrust reversal, sleeve 17 and plates 18 are rotated on tube 14 through thirty degrees, so that the gas issuing from duct 11 passes into the sector shaped spaces between adjacent ducts 40. These spaces contain deflecting vanes 20 and 21. the latter being inclined as shown in Fig. 2, except for the upstream vane, so that the deflected gases have a lateral component of motion. The spaces are blanked off at their downstream ends by walls 22. Fig. 3 shows a pod-mounted engine supported by a strut 24 depending from a wing 23. To avoid deflecting gases onto the wing, the upper sets of vanes 21b are inclined so that the gases follow arrows 41. To balance out non-axial forces, the vanes 21a only deflect the gas forwardly and radially (arrows 42), and the lower vanes 21b deflect the gases as shown by arrows 43. To reduce drag, six members of sector-shaped section normal to the nozzle axis, each formed by radial walls 25, fairing 26, and a wall 28, are secured to tube 14 Fig. 1. Each wall 25 is continued outwardly of the fairing 26 to form an open trough 29. According to the Provisional Specification, each trough 29 may be closed by an outer fairing at the radially outer ends of walls 25 to form a duct. Bridge members 30 extend each wall 25 forwardly and are secured to duct 11. Specification 811,455 is referred to.

Abstract: 398,108. Preventing priming in boilers. STIRLING BOILER CO., Ltd., 32, Farringdon Street, and NOBLE, E. E., 3, Highcroft, Kingsbury, both in London. March 7, 1933, No. 6948. [Class 123 (ii).] Dry pipes for use in steam drums comprise a pressed plate 9 of trough or triangular shape in section extending across the outlet nozzles lengthwise of the drum and secured against the upper side of the drum shell. On one or both side walls at or near their upper edge ports 8 are formed and a deflecting plate or plates 11 attached to the side wall adjacent the ports direct steam downwardly towards the narrower portion of the pipe. The ports may be formed by folding in triangular flaps 10 made by incisions in the wall and welding them to the plate 11. The ports may be oppositely directed on the two sides of the outlet to direct steam therefrom. Baffles 15 are secured over drain pipes 14. Safety valve outlets may be located within the space bounded by the dry pipe and a tube may convey steam direct thereto from the drum.

IPC: G06C15/02
Filed: 1968-02-13
Abstract: 1,212,882. Currency-convertible calculator; transfer mechanism. BURROUGHS CORP. 13 Feb., 1968, No. 6989/68. Headings G4B and G4D. A printing calculator for calculating in sterling or decimal currency comprises an adjustable member 95 (Fig. 3) movable between a first and a second position in which it limits movement of the first and third order print bars, respectively, different type sleeves being attached to the first order print bar for the different settings of the member, an accumulator wherein the first order accumulator wheel has 12 teeth, one of which is a wide transfer tooth, and the third order accumulator wheel 63<SP>1</SP>, Fig. 5, has ten teeth of which alternate teeth project rightwardly to form transfer teeth 65 and one tooth projects leftwardly to form a transfer tooth 65<SP>1</SP>, and a co-operating transfer mechanism settable to operate from either the left or the right toothextensions of wheel 63<SP>1</SP>. The member 95, Fig. 3, has two projections 95A and 95B whereby projection 95A obstructs a lug 31C on the third order print bar, thereby restricting it to printing 0 or 1 when the slide is in a leftwards (sterling) position on shaft 97, and whereby projection 95B obstructs a lug on the first order print bar, thereby restricting it to printing ¢ new penny when the slide is reset in a rightwards decimal position. The first order print bar carries a type sleeve bearing the numerals 0-11 in the sterling mode and a type sleeve bearing the numerals 1-5, ¢, in the decimal mode. Transfer mechanism.-Co-operating with the transfer teeth of the third order accumulator wheel 63<SP>1</SP> (Fig. 5) are transfer pawls 67A and 67B which are rotatable about a shaft 71 and pivotally coupled to links 69A and 69B. Rotation of the links is transmitted to member 79<SP>1</SP>, rotatable about shaft 85, through a longitudinally slidable coupler 81, which rotation disengages a projection 79A from a projection 91A of a stop member 91, whereupon the fourth order add rack 39 moves forward, spring- urged, rotating member 91 about shaft 93, and produces a one-digit transfer in the fourth order accumulating wheel. For sterling operation coupler 81 is put in a rightwards position so that its stud 77<SP>1</SP> projects through an aperture 75 in link 69A and the transfer mechanism is operated when teeth 65 rotate pawl 67A. For decimal operation the coupler 81 is stationed leftwardly so that stud 77<SP>1</SP> is withdrawn from the link 69A, and the transfer mechanism is then operated only by tooth 65<SP>1</SP> acting upon pawl 67B.

Title: Improvements in or relating to multivibrator circuit arrangements
IPC: H03K3/12
Filed: 1938-03-07
Abstract: 514,940. Valve generating circuits. WHITE, E. L. C. March 7. 1938, No. 7067. [Classes 40 (iii) and 40 (v)] A multivibrator is arranged to give trains of impulses of different duration under control of two sets of control pulses. Negative pulses of duration G, Fig. 2, are applied to terminal A and so are fed to the grid of valve V2. Under control of these pulses, impulses of duration F are produced at terminal C, the duration being determined by the valves of condenser C2 and resistance R2 and by the potential at D. The potential at D is varied by a second series of control pulses B1, Fig. 2, applied at terminal B so that for the duration of these pulses the output pulses of the multivibrator have a duration H, the output waveform being of the form shown at C1 in Fig. 2. The mean potential at point D can be adjusted at P. Specifications 455,858, 456,840 and 470,495 are referred to. The invention can be used for the mixing and diffusing of line and frame synchronising pulses in television. Reference has been directed by the Comptroller to Specification 499,755.

Abstract: 940,357. Overload release and ratchet clutches. FORD MOTOR CO. Ltd. Feb. 23, 1962 [April 28, 1961], No. 7098/62. Headings F2C and F2U. A friction torque-limiting and overrunning clutch comprises driving 15 and driven 17 plates urged together by relative rotation of a pressure plate 25 and the driven shaft 11 due to torque from frictional drag between the pressure plate and the driving plate, means being provided to limit the pressure between the plates. The driving plate 15 is held between the driven plate 17 splined to the driven shaft 11 and the pressure plate 25 free for limited axial and rotational movement relative to the driven plate 17. Axial pressure to engage the clutch is provided by relative rotation of the pressure plate 25 causing tilting of spherical washered bolts between the pressure plate and a follower 29, the pressure being transmitted from the follower to the driven plate by a Belleville washer 30 having substantially flat stress-strain characteristics. Relative movement of the pressure and follower plates is restricted by studs 40 rigid with the driven plate and engaged in slots in the follower and pressure plate such that in one direction of drive torque capacity is limited and on torque reversal the clutch substantially frees. A tickler spring 44 ensures slight rotational bias between the pressure and driven plates to ensure engagement.

Abstract: 617,055. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Ltd., MURTAGH, H., and TAYLOR, J. A. May 28, 1942, No. 7250. [Class 97 (iii)] In a gyrovertical comprising a frame or rotor case carrying one or more stabilising rotors, the stabilized rotor case or frame is carried in a first gimbal frame which is itself carried in a second gimbal frame and means are provided for controlling at least one of the gimbal frames so that in all manoeuvres three degrees of freedom are retained. As shown in Fig. 1, an air-driven rotor 14 spins within a case 13 supported by a gimbal ring 10 and forked frame 7 rotatable respectively about axes C, C<1>, B, B' and A, A<1>, and all free to turn through 360 degrees. The rotor case is erected by pendulous U-shaped shutters 33, 331 and 39, 39<1>, Fig. 3, pivoted on the upper part of the rotor case and variably intercepting air jets issuing through orifices 30, 31<1> and 31, 31<1> provided in the floor of the rotor case. The forked frame 7 is rendered pendulous by a weight or as shown, by two mercury receptacles 41, 42, so as to urge the axes B, B<1> towards the horizontal and prevent the axis from coming into line with the spin axis, e.g. during 90 degree banks. The axle of the rotor case 13 carries at opposite ends a disc 47 or 48, Fig. 2, simulating the " nose " of an aeroplane and also carries two vertical pointers 49, 491 and 50, 501. The gimbal ring 10 carries part-spherical screens 43, 44 to serve as backgrounds for the indicators. A ring 51 surrounding the window 2 carries a strip 52, Fig. 9, simulating an aeroplane and also carries bank angle graduations 54. The indications of the altitude of the craft are provided by the relation between whichever of the discs 47 or 48 and its associated pointer is visible in the window 2. For example, a half-loop followed by a half-turn brings the rear disc 48 and the indicator 50, 50<1> to the front immediately behind the window. In Fig. 9 the dial shows level flight, whilst in Fig. 12 a combination of a climb and a right bank is shown, the " nose " 47 having moved up and the aeroplane figure 52 having banked to the right, the indications of this and other evolutions being correct in general direction as observed through the window. When, owing to a vertical dive the pointers 49, 49<1> and 50, 50<1> are no longer visible in the window additional pointers 55, 56, Fig. 2, carried by the rotor case come into view. An indication of the false vertical, for comparison with the approximately true vertical given by the pointers 49, 491 and 50, 50<1> is provided by pointers 60, 61 carried by the forked frame 7. The pointer 61 may be read against a scale of degrees 62, Fig. 12, and may be used as a correct-bank or side-slip indicator by noting its departure from the zero graduation. Specification 393,695 is referred to.
