April 29, 1931, No. 12648. Convention date, April 29, 1930. [Class 38 (iv).] Systems depending on static transformers.- The degree of boost voltage introduced into an alternating current load circuit 5 from a transformer winding such as 9 is varied in accordance with an electrical condition of the circuit, such as voltage or current, by varying the current in the saturating winding of a reactor 11 in series with the primary winding of the transformer. The saturating current is obtained through a rectifier 16, and a resistance or reactance in series is varied in accordance with the load circuit changes by a solenoid 26 subject, for example, to the load circuit voltage. The reactance has two parallel windings both interlinked with the saturating winding in such a way as to avoid inducing an alternating voltage in the saturating winding. The Figure shows a body of conducting liquid 19 arranged to shortcircuit sections of resistance 17 as the container rises with decreasing load circuit voltage under dashpot control. In a modification the core of a reactance coil in the input circuit of the rectifier is moved by similar means.

Abstract: 929,773. Slewing devices. A. E. H. VELLE. April 5, 1962 [April 6, 1961], No. 13093/62. Class 78 (4). Part of the moment necessary to slew a ship's derrick is produced by rope tackle acting on a platform 5, Fig. 1, attached to the device 4 near its mounting 3. A hoisting winch 7 may be mounted on the platform 5 or the deck of the ship. Ropes 8, 9, Fig. 2, extend from the platform round a guide rail 14 to fixed lateral points 12, 13 and serve to slew the derrick. In addition top ropes may be passed from the tip of the derrick to a top mounted on the mast 2. In the embodiment of Fig. 1 ropes 8, 9 are attached at points 12, 13 and pass up to the tip of the derrick where they merge with the top ropes at a sheave 16. The top ropes are in known manner passed round two winches to provide luffing and slewing movements. The entire slewing moment may be provided by the platform ropes, a single luffing rope being provided in addition. In a further embodiment, Fig. 4, top ropes 18, 19 pass over a sheave at the derrick tip, down to the front of the platform 5 where they merge with the platform ropes 8, 9 and then via the fixed lateral points to the winches. Alternatively, the ropes 8, 9 may be fixed to the lateral points and the ropes 18, 19 extended down to the winches. The embodiment shown in Fig. 7 is similar to that of Figs. 1, 2 except that the ropes 8, 9 are attached to the front of the platform and extend via the lateral fixed points to the derrick tip where they merge with the top ropes 18, 19. The platform and top ropes may be kept separate, Fig. 8, the platform ropes being passed from the front of the platform via the fixed lateral points to a winch coupled to and having a smaller diameter than the topping winch. In Fig. 9 the top ropes pass down to the winches via sheaves to which one end of the platform ropes are attached, the opposite ends of the latter being fixed to the front of the platform. Alternatively, the platform ropes may be fixed to the lateral points. Bipod masts may be used throughout.

In a radio communication system of the type described in Specification 1,033,301 in which the receiver includes a parametric amplifier having signal and idler frequency resonant circuits, and the transmitter transmits two waves having frequencies corresponding to the signal and idler frequencies respectively which are each modulated by the same signal, the two waves are arranged as mirror image sidebands of an imaginary carrier wave signal and a carrier wave signal is transmitted which is phase-shifted from the imaginary carrier wave by an amount within the range 70 to 110 degrees. At the receiver the carrier wave is separated from the sidebands after amplification in the parametric amplifier and is used to control the phase of an oscillator which provides the pumping frequency to drive the amplifier. In one embodiment, Fig. 6, the incoming signal at the receiver is supplied to a parametric amplifier 53 through a circulator 52, the pumping frequency for the amplifier being supplied via a frequency-doubler 56 from an oscillator 55 providing oscillations at the frequency of the carrier wave. The amplified signal is supplied to the circulator 52 and a filter 58 selects the sideband signal for utilization at 59. A further filter 57 selects the carrier wave which is supplied to a phase detector 60 together with the output of the oscillator 55, any resulting error signal providing automatic phase control of the oscillator. In a modification, Fig. 7 (not shown) the incoming signal is supplied via a circulator 62 to parametric amplifier 63 and the carrier wave and sideband signals are selected by filters 64, 65 respectively, the sideband signal being supplied via a frequency-changer 67 controlled by local oscillator 68, I.F. amplifier 69 and demodulator 70 to an output circuit 72. The carrier wave is supplied to a mixer 66 receiving an input from a local oscillator 73 and the resulting I.F. signal, i.e. 30 Mc/s., is amplified at 74 and supplied to a phase detector 75 where it is compared with a 30 Mc/s. signal from a stabilized oscillator 76, the output of the phase detector being supplied via a filter 77 to phase-control the oscillator 73. The output of the oscillator 73 is also supplied to a mixer 78 together with the output of the oscillator 76 to reconstitute the carrier frequency, which is supplied via a filter 79, frequency-doubler 80 and phase adjuster 82 to drive the parametric amplifier 63.

Abstract: 514,490. Milling. INGERSOLL MILLING MACHINE CO. May 4, 1938, No. 13300. Convention date, Sept. 24, 1937. [Class 83 (iii)] Milling-machines; cutters.-In milling a plane or smooth surface, the edges of the cutter have individual lengths greater than the width of the layer to be removed, and feed takes place along a chord-like path at one side of the cutter axis and between the orbits defined by the inner and outer ends of the edges. The plane of the orbits is inclined at such a small angle to the plane of the finished work surface that very long thin overlapping chips of metal are removed. The length is preferably more than ten times the maximum thickness. A machine for carrying out the above method comprises a cutter having a series of radial blades lying ori a shallow conical frustum with its axis coincident with the rotational axis and means for supporting the work with the plane of the final surface tangential to the frustum and for feeding the work longitudinally of the plane and transversely of the line of tangency. Each blade 4 is held in a slot 3 of the cutter head by means of wedge 7 and screw 8. In one form of machine, Fig. 22, a number of work pieces 50 are held in sockets around the periphery of a table 51 adapted to rotate about an axis 53 inclined to the axis 9 of the cutter. A cam 55 on the housing operates clamping devices 56, by which the work is automatically clamped while passing through the arcuate cutting zone and unclamped in the-loading and unloading positions. The table and cutter may be arranged eccentrically as shown in Figs. 24 and 25.

[Class 40 (iv)] An electromagnetic telephone instrument, particularly suitable for use in testing other telephone instruments, comprises an electromagnetic unit of the balanced armature type, a stiff moving system including the armature 6 and diaphragm 9, a chamber in front of the diaphragm approximating in volume to that of the human external ear, and a closed chamber 14 behind the diaphragm. The diaphragm is of mica and is clamped between two recessed annular discs 11, 12, the recesses in which form part of the above-mentioned chambers. The rod 8 connecting the armature to the diaphragm passes through a bush 15 packed with a mixture of grease and graphite to render the rear chamber 14 air-tight to damp the diaphragm. The electromagnetic unit and the diaphragm assembly are secured rigidly together and resiliently mounted as a whole between a rubber block 18 and rubber annulus 20 in an inverted cup-like casing 21 secured to the base 19. The instrument to be tested is placed against the mouth of a rubber ring 25 sprung into a recess in plate 24. The total volume of the sound passage formed by the mouth of the ring 25, and the apertures in members 24, 21, 20 and 11 approximates to that of the human ear. The rod 8 is connected to the diaphragm 9 by similar conical washers 10 and nuts on each side of the diaphragm. The moving system has a resonant frequency near or above the upper limit of the operative frequency range and the associated circuit may have a resonant circuit tuned to the same frequency so as to nullify its effect. The output circuit of the instrument may also include a step-up transformer, the secondary of which in conjunction with a capacitance resonates at a frequency near the lower limit of the operative frequency.
