Title: Improvements in or relating to aircraft
IPC: B64C13/00
Filed: 1944-03-27
Abstract: 578,892. Controlling aircraft. MILES AIRCRAFT, Ltd., and MILES, G. H. March 27, 1944, No. 5642. [Class 4] A twin or multi-engined aircraft is provided with twin fin-and-rudder assemblies, the fins being movable under the control of the pilot from their normal parallel disposition into a position in which they converge forwardly to present a "toed-in" appearance in plan, in order to counteract the tendency to yaw in the event of failure of one or more engines, particularly during, or immediately after, takeoff, or when making an engine - assisted approach. In the case of a twin-engine machine, Fig. 1, the fin-and-rudder units are arranged on or substantially on the thrust centre lines 3 of the airscrews, and the fins 2 are capable of angular movement about the rudder hinge axes 5. Preferably the rudders also partake of the angular movement retaining their normal in-line relationship with the fins when the controls are centralised. The fin-and-rudder units may be capable of'differential operation to assist in directional control in the event of partial engine failure during normal flight. In order to augment the force exerted on the outer -surfaces of the fin-andrudder units when in the " toed-in " position, the thrust centre lines of the airscrews may diverge in the forward direction, Fig. 3 (not shown). According to the Provisional Specification the fins and/or the rudders may be capable of movement into the "toed-in" position.

Title: Improvements relating to the control of d.c. electric motors
IPC: H02P5/00
Filed: 1947-02-27
Abstract: 627,090. Motor control systems. TREWEEK, K. H., and FORREST, R. H. Feb. 27, 1947, No. 5701. [Class 38 (iv)] [Also in Group XXXVII] A control system for a D.C. motor comprises a resistance bridge, one arm of which contains the motor armature, the supply being connected across one diagonal and a detecting device being connected across,the other which is sensitive to variations in the back E.M.F. of the motor, and is used to control the direction, or the amount of the driving torque of the motor in accordance therewith. In Fig. 1, the armature of a D.C. motor M is connected in one arm of a resistance bridge. The detecting device consists of two coils Q and Z on a polarized relay which controls reversing switch G connected in the supply circuit. The bridge is arranged to balance at zero motor back E.M.F., so that when operating normally, the current through coil Q is proportional to the back E.M.F. This relationship is independent of the supply voltage, and with a permanent field the back E.M.F. varies only with motor speed. A controlling signal current is passed through coil Z which determines the direction of the motor rotation, and also the average speed around which hunting will occur. In an alternative arrangement, additional resistances are included in arms A and B of the resistance bridge which may be shorted out by a switch under the control of the polarized relay, instead of using the reversing switch G, whereby the series resistance in the armature circuit may be periodically reduced to provide a similar hunting operation. Fig. 3 shows a further alternative in which two valve-controlled relays are provided in the detector circuit in place of coils Q and Z, so that either a positive or negative control signal may be used. Valve VI controls contact PI, and valve V2 controls contact P2. The control signal is applied in push-pull to the two control grids, and the valve with the positive signal controls the periodic switching in the armature circuit, of the additional resistances C and E. A further arrangement is described in which the motor field is connected across the supply, and the speed control is effected by connecting the detecting device to an adjustable point on resistances K and L, which are now constituted by a potentiometer.

Title: Air cushion conveyors
IPC: B65G15/30
Filed: 1972-02-08
Abstract: 1413983 Endless belt conveyers UNITED KINGDOM ATOMIC ENERGY AUTHORITY 15 Jan 1973 [8 Feb 1972 14 March 1972] 5805/72 and 11755/72 Heading B8A Load carriers 53 for articles (not shown), are supported on an endless conveyer belt 52 by the action of air in a pressure manifold (not shown) passing through apertures 1 controlled by valves 1a. The air traverses the belt through perforations or other pervious means to pass into an annular chamber 57 of the carrier 53. The chamber 57 is defined by inner and outer annular bellows 55, 56. A valve 58 communicates pressure developed in the central space of the bellows 56, to the bellows 55, thereby extending the latter and forming a seal with the belt surface. Pressure passing from the belt perforations through perforations 62 to the annular portion of the bellows 56 is used to operate a bellows 61 controlling the valve 58. In a simpler modification (Fig. 5, not shown), the carrier consists simply of a flexible envelope having an aperture in its lower surface for receiving air coming up through the belt. In a modification of the latter (Fig. 6, not shown), the envelope is connected via a valve (72) with a source of pressure, and contains a rigid annular member (71). The upper and lower runs of the belt may lie in contact directly on top of the surface 51 (Fig. 7, not shown). The envelope may be secured to the belt as in Fig. 5 of the parent Specification. An additional number of apertures 1 may be provided in the surface 51 connected to a separate source of pressure. This is to provide hovering of the load at areas of discharge from the belt (Fig. 2, not shown, and Figure of Provisional Specification 1,413,983, not shown).

Title: Method of Measuring Very Small Differences in Field Strength by Means of a Nuclear-Resonance Magnetic-Field Measuring Instrument
IPC: G01R33/022
Filed: 1967-02-08
Abstract: 1,165,285. Measuring magnetic fields. LICENTIA PATENT-VERWALTUNGS-G. m. b.H. Feb. 8, 1967 [Feb. 8, 1966], No.5954/67. Heading G1N. The measurement of very small magnetic field variations, in the investigation of, e.g. the homogenety of the field between poles 1, Fig. 8, is carried out using two nuclear resonance magnetometor probes each including a sample situated in an h. f. field generating coil 4 or 6, connected together in series or parallel and forming part of an oscillator 8. Field modulating coils 5, 7, energised from a source 9 of frequency, e.g. 50c/s, which also supplies the horizontal deflection voltage of frequency 100c/s of a C.R.O. 11, are arranged round the samples so that the modulating fields Hm 1 , H m2  are 180 degrees out of phase. The output from the oscillator 8, after demodulation at 12 and amplification at 13, is fed to the C.R.O. 11 where a trace is produced whose form is dependent on the relative values of the Larmor frequencies of the samples and the driving high frequency, i.e. on the corresponding values of the fields, H 1 , H 2  and Ho. If the field Ho, corresponding to the driving high frequency, is slightly less than the fields H 1 , H 2  under investigation, Fig. 4, the trace consists of two pairs of peaks whose separations is proportional to the field difference provided that the modulating fields have equal amplitudes, see also Fig. 6 (not shown). As the field Ho is increased the four peaks will merge into two, Fig. 5, having the same separation as before when Ho is given by the mean value of H 1  and H 2 , this is so even if the modulating fields have different amplitudes, Fig. 7 (not shown). The separation of the peaks may be measured directly from the C.R.O. or may be measured by applying a further variable D.C. field to the modulating field of one of the probes until the pairs of peaks or the two peaks coincide, at which point the applied field, obtained by a measure of the current flowing through the field producing coils, is equal in magnitude to the field difference.

Abstract: 485,499. Wrapping machines. FORGROVE MACHINERY CO., Ltd., and GROVER, F. March 2, 1937, No. 6195. [Class 94 (i)] Relates to mechanism for driving the twist grippers of wrapping-machines such as are described in Specifications 396,212 and 442,803. The jaws 12 are driven by gearing 19, 20 and shaft 21 so as to have a speed varying from a maximum to nil. The main driving shaft 18 carries a crank to which is fixed a driving gear wheel 23, a pin 24 coaxial with which carries a link 25 having a floating spindle 26 at the other end. The spindle carries an intermediate gear 27 and the end of a link 28 pivoted at its upper end to the driven shaft 21. This shaft carries a gear wheel 29 meshing with the intermediate gear 27. As the driving shaft 18 rotates in a clockwise direction, Fig. 3, the gear 23 is carried bodily round, and imparts anticlockwise rotation to the intermediate gear 27 and causes the floating spindle to oscillate in an arc about the driven shaft 21. This causes a dwell in the rotation of the driven shaft sufficient for the introduction of the article and wrapper between the jaws, which are opened and closed at the appropriate times by a rack-rod 16 as described in Specification 442,803. The dimensions of the parts may be varied to obtain a slight reverse movement of the driven shaft.
